How are unicellular protists and multicellular protists similar?
Answer:
Most protists are so small that they can be seen only with a microscope. Protists are mostly unicellular (one-celled) eukaryotes. ... Multicellular protists, however, do not show cellular specialization or differentiation into tissues. That means their cells all look the same and, for the most part, function the same
Explanation:
Most protists are so small that they can be seen only with a microscope. Protists are mostly unicellular (one-celled) eukaryotes.
What is protists?Protists are a diverse group of organisms that do not fall within the categories of an animal, a plant, a bacterium, or a fungus. Although there are several exceptions, most are tiny and comprised of just one cell (unicellular).
Because they have a nucleus and other membrane-bound organelles, protists are eukaryotes (structures that perform a specific job).
Simple creatures like amoebas and one-celled algae were once included into the kingdom Protista, a single taxonomic category. Protists can get their food in a variety of ways. Protists can be heterotrophs or photosynthetic, according to Simpson.
Therefore, Most protists are so small that they can be seen only with a microscope. Protists are mostly unicellular (one-celled) eukaryotes.

genetic drift always causes an allele to increase in frequency from one generation to the next. group of answer choices true false
The statement that genetic drift always causes an allele to increase in frequency from one generation to the next is false. Genetic drift is defined as a random change in the frequency of an allele in a population.
It is a mechanism of evolution that happens in populations that are small and isolated from other populations. In small populations, genetic drift can result in the loss of an allele or the fixation of an allele. In the case of the loss of an allele, it means that the allele disappears from the population, and in the case of fixation, it means that the allele becomes the only allele present in the population.
Alternatively, a rare allele may become fixed in a population if it gets a selective advantage, and its frequency becomes higher than any other alleles present in the population. Genetic drift is more likely to have a significant impact on the genetic composition of small populations.

Consider the image of the female reproductive organs. Where in the diagram would a fertilized egg implant and develop into the fetus?
In the uterine lining, the fertilized egg implants. The uterus grows to accommodate the growing and developing foetus as it develops.
What is Uterine lining?The deepest layer of tissue line the uterus in females of reproductive years is referred to as the uterine lining or endometrium. The endometrium is a highly specialized tissue that changes cyclically throughout the menstrual cycle in response to hormonal signals.
In order to be ready for potential implantation of a fertilized egg, it thickens and fills out with blood vessels and nutrition. In the absence of fertilisation, the process restarts when the thicker endometrium is removed during menstruation. The endometrium, on the other hand, supplies nutrition and care for the growing embryo and foetus during pregnancy if a fertilised egg does settle in the endometrium.
Therefore, in the uterine lining, the fertilized egg implants. The uterus grows to accommodate the growing and developing foetus as it develops.

organism under the microscope first? ws Robert Hooke Rudolf Virchow Anton van Leeuwenhoek 5 um Photo by Brudersohn
Answer:
The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke. Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb. Hooke made the drawing in the figure below to show what he saw. As you can see, the cork was made up of many tiny units, which Hooke called cells.
Soon after Robert Hooke discovered cells in cork, Anton van Leeuwenhoek in Holland made other important discoveries using a microscope. Leeuwenhoek made his own microscope lenses, and he was so good at it that his microscope was more powerful than other microscopes of his day. In fact, Leeuwenhoek’s microscope was almost as strong as modern light microscopes. Using his microscope, Leeuwenhoek was the first person to observe human cells and bacteria.

wallet)
Ribose
ОАТР
ADP
Adenosine
Answer:
It's definitely "ADP" the third choice
The correct answer from the available option as to which can be compared to a battery in need of recharging would be ADP.
ADP, Adenosine Diphosphate functions in the metabolism of energy in the body system of living organisms. ADP is comparable to a battery that needs recharging because further phosphorylation of the compound will yield ATP, a molecule that can be used for energy activities in the body system of organisms.The hydrolysis of the ATP release energy through the breakage of the high energy phosphoanhydride bond, resulting in the formation of ADP which is then ready for another recharge.

is traditional ecological knowledge important to consider in the
scientific study of nature? Provide a example
Traditional Ecological Knowledge (TEK) is important to consider in the scientific study of nature because it provides valuable insights into local ecosystems, biodiversity, and sustainable practices.
Traditional Ecological Knowledge refers to the knowledge, practices, and beliefs developed by indigenous and local communities based on their interactions with the environment. This knowledge encompasses a deep understanding of local ecosystems, including the behavior of plants, animals, weather patterns, and ecological interdependencies. Integrating TEK into scientific studies brings several benefits.
Firstly, TEK provides a holistic view of the environment, considering the social, cultural, and spiritual aspects intertwined with nature. This perspective can contribute to a more comprehensive understanding of ecological systems and help identify sustainable practices.
Secondly, TEK offers insights into the impacts of climate change and other environmental disturbances. Indigenous communities often possess detailed observations and long-term records of environmental changes, which can supplement scientific data and improve predictions and mitigation strategies.
For example, indigenous communities in the Arctic have traditional knowledge about ice formation, wildlife migration patterns, and weather changes. This knowledge has proved invaluable in understanding the impacts of climate change and developing adaptive strategies for Arctic communities.
Overall, incorporating Traditional Ecological Knowledge in scientific research fosters a more inclusive and multidisciplinary approach, respecting the wisdom and expertise of indigenous and local communities while enriching scientific understanding and promoting sustainable conservation practices.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?
A.
Both blood and intestinal cells take in glucose by passive transport.
B.
Blood cells take in glucose by active transport and intestinal cells take in glucose by passive transport.

bob's father is a universal blood donor and his mother is an universal blood receiver (homozigote rh). what two possibilities of blood types can bob have?hint - write like this: x-, x-
Bob's father is a universal blood donor, meaning he has blood type O-. His mother, on the other hand, is an universal blood receiver (homozygous) , which means she has blood type AB+. Since blood type is determined by the genes inherited from both parents.
It's important to know the blood types of both parents to determine the possible blood types of their offspring. There are four major blood types, which are A, B, AB, and O. Each blood type is determined by the presence or absence of certain antigens on the surface of red blood cells, and each blood type is either Rh positive or Rh negative. Bob's mother, as stated earlier, is AB+ (homozygous), which means she inherited an A allele and a B allele from her parents.
Since both parents are universal donors and receivers, it's safe to assume that they do not carry the dominant O allele. Thus, Bob inherited either an A allele, a B allele, or both from his mother.On the other hand, Bob's father has O- blood type. This means that he is homozygous recessive for the blood group O. In this case, it's safe to assume that Bob inherited an O allele from his father.
So, considering the blood types of Bob's parents, we can determine the two possibilities of blood types that Bob can have:AB-: Bob could inherit the A and B alleles from his mother, and the recessive allele O from his father. This would give him blood type AB-.O-: Bob could inherit the recessive O allele from both parents, which would give him blood type O-.
In conclusion, Bob could have either AB- or O- blood type based on the blood types of his parents.

what is photosynthesis
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
Describe how ATP is produced in the light reactions.
Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
Light energy splits the water molecules into hydrogen and oxygenThis process is called photolysisThe hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product .
2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis
)
Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called Adenosine Triphosphate (ATP)
Hope this helps.
The process of how ATP is produced in the light reactions is explained below.
The light-dependent reaction often absorb energy through the help of sunlight and then it is is stored by two types of energy-carrier molecules which are ATP and NADPH.The energy gotten by the hydrogen ion stream gives room for ATP synthase to attach a third phosphate to ADP. Through this attachment, a molecule of ATP is formed in a process called photophosphorylation.
Light absorbed during this reaction and the energy, is used to drive electrons from water to generate NADPH and to drive protons across a membrane.
These protons that are driven often return through ATP synthase to make ATP.
Cellular respiration also produce ATP and water, that is used in different chemical reactions in the plant cell.

Which of the following processes occurs in the cytoplasm of a eukaryotic cell?
A). translation and transcription
B). DNA replication
C). transcription
D). DNA replication and translation
E). translation
translation occurs in the cytoplasm of Eukaryotic cell
correct option is E .
In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The entire process is called gene expression
In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell. The ribosome facilitates decoding by inducing the binding of complementary tRNA anticodon sequences to mRNA codons. The tRNAs carry specific amino acids that are chained together into a polypeptide as the mRNA passes through and is "read" by the ribosome.
Translation proceeds in three phases:
1.Initiation: The ribosome assembles around the target mRNA. The first tRNA is attached at the start codon.
2.Elongation: The last tRNA validated by the small ribosomal subunit (accommodation) transfers the amino acid it carries to the large ribosomal subunit which binds it to the one of the preceding admitted tRNA
3.Termination: When a stop codon is reached, the ribosome releases the polypeptide. The ribosomal complex remains intact and moves on to the next mRNA to be translated.
