Can you succeed if you don't get good grades?The truth is that grades are really not that significant. Regrettably, valedictorian status doesn't carry much weight in the actual world. After having less than outstanding academic careers, some of the world's most successful individuals have gone on to have amazing careers in business and public life.
Are grades crucial to success?When it comes to getting into college, high school grades are most important. When considering whether to admit or reject a student, institutions may take into account their grade point average (GPA).

Answer this please ASAP FOR 30 POINTS!!!!
Answer:
A
Explanation:
Hello, so we can do this question two ways. 1, we can know what kind of relationship the two types have or 2, we can analyze each relationship and see if it would increase or decrease.
Starting with option 2, we can look at A. A says the population would stay stable because of a commensal relationship. In a commensal relationship, one party benefits and the other neither gains or loses anything. Thus, A could be true because the population would stay stable in this case.
Looking at B, we see it says the population would increase because it has a mutualistic relationship. However, in a mutualistic relationship both species benefit. If the wrasse population died more, that would NOT benefit the other species in a mutualistic relationship, thus B can be eliminated.
Answer C says it would decrease because of its predator and prey relationship. Depending on which one was the predator and which was the prey, one species could benefit from the death of the other while the other didn't. For example, if the wrasses were the prey, the predators would also decrease because they could not eat as well, but if the wrasses were the predators they other population would increase because they would be eaten less. Thus we cannot rule out answer C.
D for an answer is like C, depending on the roles of which was which D could or could not be the answer.
Although method 2 helps eliminate B it still does not tell us the answer, so we look to our knowledge of wrasses and titan tigerfish. Wrasses and titan tigerfish have a commensal relationship. Therefore, one can benefit and the other is neither harmed nor benefited. This relationship is also called symbiotic. Thus, the wrasse population could decrease and since the titan tigerfish do not experience benefits or harm from that species their population will remain the same.

Photosynthesis is the process by which autotrophs produce their own food. It is an anabolic reaction in which energy is stored (endergonic). Consequently, Cellular Respiration is the opposite of Photosynthesis. In Cellular Respiration, heterotrophs consume food to produce energy. It is a catabolic reaction in which energy is released (exergonic). Both metabolic processes are essential to sustain life. Describe the similarities and differences between the biochemical pathways of Aerobic Respiration and Photosynthesis in eukaryotic cells. Include in your discussion the major reactions, the end products, and energy transfers.
The similarities between aerobic respiration and photosynthesis are that they are both metabolic reactions and ATP is used at some point in each of the reactions.
The difference between aerobic respiration and photosynthesis is that:
aerobic respiration produces carbon dioxide and water as an end-product whereas photosynthesis produces oxygen and glucose as an end-product. aerobic respiration uses oxygen and glucose as starting materials whereas photosynthesis uses carbon dioxide and water as starting materials ATP is used by photosynthesis, whereas ATP is produced in cellular respirationThe equations of photosynthesis and celli=ular respiration are given below:

Cell theory describes the basic function of all living things. Why is this considered a theory and not a law? Responses It was based on observations and does not require math calculations. It was based on observations and does not require math calculations. It is based on opinion and not facts. It is based on opinion and not facts. It can only be changed if a law is developed first. It can only be changed if a law is developed first. It was developed by a single person and not a large group of scientists.
Answer:
What is the cell theory? It has three main parts:
1. All living things are made up of cells.
2. Cells are the basic building blocks of life.
3. All cells come from preexisting cells created through the process of cell division.
As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:
4. Energy flow occurs within cells.
5. Hereditary information is passed from cell to cell.
6. All cells have the same basic chemical composition.
So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.
The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the action!

2) Jessica and Maria are both making slime with different recipes. Jessica’s recipe calls for \large 1\frac{1}{2} cups of flour and Maria’s recipe calls for \frac{2}{3} cups of flour. How many cups of flour will they need in order to make both of their batches of slime?
With the help of fraction addition it is found that 13/6 cups of flour will be needed to make both of Jessica and Maria's batches of slime.
How are fractions added?
There are three easy steps to add fractions:
Step 1: First, ensure that the denominators (bottom numbers) are the same. If the denominators are not same take their LCM to make the denominators same.
Step 2: Add the higher numbers (the numerators), then multiply the result by the denominator.
Step 3: Simplify the fraction.
Amount of flour required in Jessica's recipe = 1 and 1/2 cups (mixed fraction) = 3/2 cups Amount of flour required in Maria's recipe = 2/3 cups.
Here the denominators of the fractions 3/2 and 2/3 are not same, therefore we need to find the LCM (lowest common factor) of 2 and 3 in order to make the denominators same for addition. The LCM of 2 and 3 is 6.= 3/2 + 2/3 = 9/6 + 4/6 = 13/6
Thus 13/6 cups of flour are needed to make both of their batches of slime

Pesticides and fertilizers create water and air contamination and significant health consequences. Chemicals are regulated to reduce water contamination.
What are pesticides?Insecticides, fungicides, and nematicides are all examples of pesticides. It is essential to exercise population control over the unwanted organisms and insects that cause severe damage to the crops. On the other hand, pesticides can never be used in excess, as this would have a negative impact on living things.
Fertilizers are added to the soil in order to improve its fertility and thus the development of plants. In addition, they contain hazardous substances.
Both insecticides and fertilizers are known to include compounds that are potentially harmful. These chemicals almost certainly will lead to the contamination of water and air, in addition to causing health problems for the organisms in the surrounding area.
Contamination of water is a critical problem that has been on everyone's minds for a considerable amount of time. It is possible to lessen the amount of water contamination by lowering the amount of pesticides and fertilizers that are used.

What important function can elodea cells perform that onion cells cannot?'
Elodea cells is capable of photosynthesis, while onion cells cannot
difference between elodea cells and onion cellsElodea cells and the plant itself serve as producers in natural settings because they are photosynthetic plants. Plants use light energy to transform carbon dioxide and water into sugars and oxygen through a process known as photosynthesis. It is the primary pathway for energy to enter an ecosystem.
Elodea cells photosynthesize because they develop in sunlight and are frequently categorized as waterweeds.
Onions cells, on the other hand, grow below the surface, therefore their cells cannot photosynthesize. Additionally, elodea cells have a vacuole that is filled with cell sap, a fluid that is mostly composed of water.
Conclusively, Elodea cells are structurally distinct from onion cells. Elodea cells are arranged in two layers, one of which is long and narrow and the other of which is short and wide. The cells of an onion are bigger and arranged in a single layer.

Based on its anatomy, infer which animal requires more energy: an Earthworm or a Salamander? Justify your answer.
Based on its anatomy, the animal that requires more energy is the Salamander. This is because it has a more complex anatomy and physiological structure.
Why do living organisms require energy?Living organisms require energy because they have to perform metabolic activities for proper and ideal survival of organisms. Such organisms use numerous strategies in order to accomplish the task.
An earthworm delivers energy from the environment more easily than compared to salamanders. This is because they extract food energy from decaying organic matter like plants and animals that have died.
On the other hand, Salamanders deliver energy by consuming small insects and other tiny living entities. It uses a mechanism more similar to human beings.

Calculate allele frequencies in 5th generation. Record in Lab Data
Calculate genotype frequencies and number of moths in 5th generation. Record in Lab Data
Allelic frequencies ⇒ q = 0.9, p = 0.1. Genotypic frequencies ⇒ q² = 0.81, 2pq = 0.18, p² = 0.01. Number of individuals with each genotype ⇒ homozygous recessive = 850.5 individuals. Heterozygous = 189 individuals. Homozygous dominant = 10.5 individuals.
To answer this question, we will assume this moth population is in Hardy-Weinberg equilibrium.
What is the Hardy-Weinber equilibrium?
Hardy-Weinberg equilibrium is a theory that proposes that when populations are in equilibrium they are not evolving. And if populations are not evolving, their allelic and genotypic frequencies remain the same generation after generation.
Assuming diallelic genes code for a particular feature,
Allelic frequency
f(X) ⇒ p ⇒ frequency of the dominant allelef(x) ⇒ q ⇒ frequency of the recessive alleleGenotypic frequencies
F(XX) ⇒ p² ⇒ homozygous dominant frequencyF(Xx) ⇒ 2pq ⇒ heterozygous frequencyF(xx) ⇒ q² ⇒ homozygous recessive frequencyIn populations that are in Hardy-Weinberg equilibrium, the addition of allelic and genotypic frequencies will always equal 1.
p + q = 1p² + 2pq + q² = 1Now, we will use this framework to get the allelic and genotypic frequencies of the 5th generation.
We know that,
1000 moths were released in a forest (N = 1000). 250 were white (Typica), and 750 were black (Carbonaria).A diallelic gene codes for color. The dominant allele -D- codes for black (carbonaria), and the recessive allele -d- codes for white (Typica).Once released, these individuals produced five new generations, G1, G2, G3, G4, G5.G5 is composed of 851 white individuals (typica) and 199 dark individuals (carbonaria). The total number of individuals is 199 + 851 = 1050.1) Phenotype frequencies
Now that we have the number of individuals expressing each color and the total number of individuals, we can get the phenotypic frequencies.
To calculate them we just need to divide the number of individuals with each phenotype by the total number of individuals in this generation. So,
Total number of individuals in G5 → 1050White = Typica = 851 individualsBlack = Carbonaria = 199 individuals⇒ F(Typica) = 851 / 1050 = 0.81
⇒ F(Carbonaria) = 199 / 1050 = 0.189 ≅ 0.19
Notice that these frequencies were already given in the Phenotype Frequency table.
2) Allelic Frequencies
Now, we will use the phenotypic frequencies to get the allelic frequencies.
Carbonaria (black) is the dominant phenotype, so it includes homozygous dominant individuals (DD) and heterozygous individuals (Dd). We can not get the allelic frequencies from this data.
So, to get the allelic frequencies we will use the recessive phenotypic frequency because it only includes homozygous recessive individuals, dd.
Homozygous recessive Gentoypic frequency = Recessive Phenotypic frequencyGenotypic frequency → F(dd) → Represented as q²F(Typica) = F(dd) = q² = 0.81Recessive allele → dRecessive allelic frequency → f(d) → Represented as qf(d) = q = ??
q² = 0.81
q = √ 0.81
q = 0.9
0.9 is the recessive allelic frequency.
With this data we will calculate the dominant allelic frequency. To do this, we will clear the following formula,
p + q = 1
p + 0.9 = 1
p = 1 - 0.9
p = 0.1
So, now we also know that
⇒ f(D) = p = 0.1
⇒ f(d) = q = 0.9
3) Genotypic Frequencies
Now, we need to get the genotypic frequencies, F(xx)
⇒ F(DD) = p² = 0.1² = 0.01
⇒ F(Dd) = 2pq = 2 x 0.9 x 0.1 = 0.18
⇒ F(dd) = q² = 0.9² = 0.81
4) Number of individuals
Finally, we need to tell the number of individuals with each genotype. We just need to multiply each frequency by the total number of individuals in G5.
F(DD) = p² = 0.01F(Dd) = 2pq = 0.18F(dd) = q² = 0.81Total number of individuals = 1050
⇒ DD Black -Carbonaria- individuals → 0.01 x 1050 = 10.5
⇒ Dd Black -Carbonaria- individuals → 0.18 x 1050 = 189
⇒ dd White -Typica- individuals → 0.81 x 1050 = 850.5
From this results, we can conclude that the moths population is not in H-W equilibrium, because their allelic and genotypic frequencies changed through generations.
