3.Each onion plant begins as a single cell containing 16 chromosomes. How many chromosomes are present in each of the cells that you observed
Answer:
In somatic cells, 16 chromosomes are present whereas in sex cells, there is 8 chromosomes.
Explanation:
In the somatic cells, the replication of chromosomes occur and after the replication is completed, the parent cell is divided into two daughter cells having double number of chromosome by each daughter cell i.e. 16 chromosomes while on the other hand, in sex cells, first the parent cell divides into two daughter cells and after sometime, these daughter cells are again divided having total four daughter cells each receives half number of chromosomes i.e. 8 chromosomes.
Discuss how important you think it is to protect ecosystems from human-induced change, such as changes in habitat or introduction of invasive species. Should natural conditions be preserved at all costs, should human needs always prevail, or is the answer somewhere in between? Discuss the negative consequences of taking an approach that you disagree with.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits.
Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air. Protecting wildlife and preserving it for future generations also means that the animals we love don't become a distant memory. And we can maintain a healthy and functional ecosystem.

What is the phase that not all cells enter, but it is a phase where cells are not actively dividing
Answer:
The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.
Answer:
G₀ phase
Explanation:
Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.

In a test cross, a pure-breeding plant is crossed with a plant suspected to be heterozygous (Aa). What is the genotype of the pure-breeding plant?
Answer:
aa
Explanation:
In genetics, a test cross is a cross performed to determine the unknown genotype of a phenotypically dominant organism. The test cross is done by crossing the unknown genotype with a homzygous recessive organism. The result of this cross tell us whether the unknown genotype is heterozygous or homzygous dominant.
According to this question, a test cross was conducted involving a pure breeding plant with a plant suspected to be heterozygous (Aa). Based on the explanation of a test cross above, the genotype of the pure-breeding plant will be "aa". Note; it must be recessive.

Which R group would most likely be found in a hydrophobic area of the tertiary structure of a globular protein?
Answer:
CH2-Aromatic ring
Explanation:
Amino acids with aromatic R groups are relatively hydrophobic and therefore don't interact with water molecules surrounding the protein. Tryptophan (Trp), phenylalanine (Phe) and tyrosine (Tyr) are amino acids with aromatic R groups. Since these amino acids are relatively nonpolar or hydrophobic, they participate in hydrophobic interactions that are strong when there are several residues with aromatic R groups which are stacked on one another. In this regard, it is also important to highlight that Tyr and Trp are more polar than Phe due to the hydroxyl (OH-) group in Tyr and the nitrogen in the Trp ring.

In pulsus paradoxus, even if the pulse cannot be palpated, it can still be heard by using a BP cuff and stethoscope.
a. True
b. False
Answer:
False.
Explanation:
Pulse can't be heard by using a BP cuff and stethoscope because these devices are used to measure the heartbeat and blood pressure of the body. Digital monitors display both blood pressure and heart rate, but you can determine the pulse by checking your pulse by using hand while on the other hand, heartbeats can easily be heard using a good stethoscope so we can say that pulse can't be heard through BP cuff and stethoscope.
Warfarin acts by inhibiting the activity of the VKORC1 protein, which helps to produce functional clotting factors. There is a variant in the VKORC1 gene that lowers the dose of warfarin required for treatment, and individuals with this variant have increased risk of bleeding when they are treated with warfarin. This variant is found 1639 base pairs upstream of the translational start site. This variant likely:______.
a. decreases the activity of the VKORC1 protein.b. increases the activity of the VKORC1 protein.c. decreases expression of the VKORC1 gene.d. increases expression of the VKORC1 gene.
Answer:
The correct answer - c. decreases expression of the VKORC1 gene.
Explanation:
Mutation of Guanine nucleotide into Adenosine is the reason for this particular type of mutation. This mutation expresses the less expression of the VKORC1 protein.
The mutation results in a decrease in the affinity of the binding site of the transcription factor which causes less expression. Since the VKORC1 protein is less in the body so Warfarin doses are decreased
Thus, the correct answer is - decreases expression of the VKORC1 gene.

What are the functions of leaves? (Select all that apply.) PLEASE ANSWER ASAP AND GET 25 POINTS
release water vapor
absorb water and nutrients
store water and glucose
perform photosynthesis
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Conifer Leaf.
Microphyll Leaf.
Megaphyll Leaf.
A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

Solutions having osmotic pressures more than those of body fluids are called Group of answer choices hyposmotic. neosmotic. hyperosmotic. magnosmotic. isosmotic.
Answer:
hyperosmotic
Explanation:
Osmosis across a membrane occurs in nature as a result of concentration gradient i.e. difference in the solute concentration. Based on the concentration of solute in a solution which determines the osmotic pressure, a solution can either be hyperosmotic, hypoosmotic or isosmotic.
A hyperosmotic solution is that solution which contains more solute concentration in relation to another solution. In essence, a hyperosmotic solution will have more osmotic pressure than that of the body fluid. This will cause water to flow out of the body into the solution.
1. A week after returning from a backpacking trip, four teenagers developed nausea and severe diarrhea. All had consumed untreated water from a stream which doctors concluded was infested with the organism, Giardia. Think about the symbiotic relationships that you studied in this unit. What type of relationship exists between the teens and the organism?
2. As humans burn fossil fuels for energy, the percent of carbon stored in fossils is reduced while the carbon in the atmosphere is increased. If green plants are also being removed, how might the carbon cycle and greenhouse effect be influenced?
3. How are decomposers critical to the carbon cycle?
Answer:
Explanation:
1) The relationship that exists between the teens and the organism (Giardia) is Parasitism. Because in such symbiotic relationship one species (the parasite-Giardia) benefits while the other species (the host- the teens) is harmed.
2) Plants remove Carbon dioxide (a major green house gas) from atmosphere during photosynthesis. But, if plants are also being removed with increase in use of fossil fuels, the CO2 that escapes the fossil fuels will remain in the atmosphere for longer as there are not enough plants to "suck" them back into a stored form of Carbon. Carbon Dioxide increases green hourse effect thus green house effect will increase and earth's temperature might rise due to this.
3) Without decomposers we would not be able to continue the carbon cycle because we could not release the stored carbon from plants and animals into the atmosphere. Decomposers break down dead material from organism and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. Without them, we could not recycle nutrients or carbons in our ecosystem and thus, they are critical for the carbon cycle.
