Class I MHC molecules B. activate cytotoxic T cells.

Antigen presented in class I MHC molecules interacts with the T cell receptor (TCR) of cytotoxic T cells. There is also an interaction of CD8 on the T cell with MHC I.

Cytotoxic T cells have receptors that recognize and bind to specific peptide-MHC complexes, and when they encounter a cell presenting an abnormal peptide, they become activated and initiate an immune response against the infected or abnormal cell. This response can include the release of cytokines and the killing of the infected or abnormal cell by the cytotoxic T cell.

On the other hand, B cells are activated by helper T cells, while MHC I molecules are found on each and every nucleated cell in the body, and MHC I molecules present endogenous antigens.

Therefore, The correct option is B. Activate cytotoxic T cells

Explanation:

Plants have two major structural systems: the root system and the shoot system. ... The shoot system transports water and nutrients to leaves and flowers. The leaves of the plant are the main location for photosynthesis. Plant reproduction occurs through pollination of the flower and fertilization.

Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on). Most plants are vascular, which means they have a system of tubules inside them that carry nutrients around the plant.

Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells. Each of these cellular structures plays a specific role in plant structure and function.

Answer:

Since you didn't put answer choices, the answer you are looking for should be in the explanation.

Explanation:

Protein synthesis is needed to create new proteins for the cell. Proteins are essential because they perform functions for the cell, such as catalysis and communication, and form important structures like the cytoskeleton. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes these steps:

(1) Activation of amino acids:

(2) Transfer of amino acid to tRNA:

(3) Initiation of polypeptide chain:

(4) Chain Termination:

(5) Protein translocation:

Answer:

mRNA strand is formed, mRNA is processed, polypeptide chain is formed, protein is modified

Explanation:

Here it is:

1. DNA is used as a template to create mRNA

2. mRNA molecule binds to a ribosome

3. tRNA binds to the ribosome (specific tRNAs bring individual amino acids reading mRNA codons)

4. Amino acids are bonded together to make a poly peptide

5. The ribosome releases both the mRNA molecule and the polypeptide ( when it encounters translation termination codon on mRNA).

Answer:

Explanation:

In s phase, the dna replication take place in interphase, The dna in the nucleus replicates so that each chromosome consists of two identical chromatids, then in mitosis they are pulled apart in anaphase in which both cells have half of the chromosomes, in Telophase each chromatid contains one dna molecule, which will replicate itself during interphase before the next division.

The new cells are similar from the original ones in interphase as these will have same amount of DNAs.

The interphase phase of the cell cycle is where the majority of the life of a typical cell occurs.

Interphase is the cell's "daily living" or metabolic phase, during which it obtains and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.

The cell cycle's longest phase is interphase. This is the stage at which the cell grows and copies its DNA before entering mitosis.

Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.

In interphase, the new cells are similar to the original ones because they have the same number of DNAs.

Thus, this can be the similarity between these two.

When we compare the same gene on different organisms, those who have the least nucleotide differences are more related to each other.

Let's look at the table for the Hoxc8 gene.

We can see that the mouse and the blue whale have 4 differences in this gene, while the mouse and the chicken have 8 differences.

This means the right answer is D) A mouse is more closely related to a baleen whale because they only share 4 nucleotide differences.

A network-tree concept map can be used to compare the excretory functions of the kidneys and the lungs.

The network-tree concept map organizes information in a hierarchical manner, with the main topic at the top of the tree and the subtopics branching out from it. In this case, the main topic would be "excretory functions", with the kidneys and lungs as the subtopics branching out from it. Under the "kidneys" subtopic, one can include the functions of the kidneys in excretion, such as removing waste products from the blood, regulating electrolyte balance, and maintaining acid-base balance. On the other hand, under the "lungs" subtopic, one can include the excretory function of the lungs in removing carbon dioxide from the body.
By using a network-tree concept map, one can easily compare the excretory functions of the kidneys and the lungs side by side, and see how they differ in terms of their roles in excretion. Overall, both the kidneys and lungs play crucial roles in the excretory system of the body, and work together to maintain homeostasis.

Water flows out the cell

A microorganism that has been used in the production of sour mash whiskey is Lactobacillus bacteria.

In the production of sour mash whiskey, a portion of the spent mash (the leftover grains from a previous batch) is added to the new batch of mash along with water and cornmeal or other grains. This creates an acidic environment that is favorable to the growth of Lactobacillus bacteria. These bacteria produce lactic acid, which helps to control the growth of harmful microorganisms and contributes to the characteristic sour flavor of the whiskey. After the mash is fermented with yeast and distilled, the resulting whiskey is aged in oak barrels to develop its distinctive flavor and color.

The neuron will fire if "excitatory-signals" are stronger than inhibitory  signals.

The neuron will fire if the summation of excitatory signals exceeds the summation of inhibitory signals, which leads to net depolarization of neuron's membrane potential.

Neurons receive inputs from other neurons through synaptic connections, which can be either excitatory or inhibitory in nature. Excitatory signals, often mediated by neurotransmitter glutamate, cause depolarization of neuron's membrane potential, making it more likely to generate an action potential.

The inhibitory signals, mediated by neurotransmitter GABA, cause hyperpolarization, making it less likely for neuron to fire. The balance between these excitatory and inhibitory inputs determines the overall activity and firing behavior of neuron.

The estimated time it will take for the population to reach 5000 bacteria is approximately 13.4 hours.

To estimate when the population will reach 5000 bacteria, we can set up the equation P(t) = 5000 and solve for t.

The given equation for population growth is P(t) = 1000e^(0.12t). To solve for t, we can substitute 5000 for P(t):

5000 = 1000e^(0.12t)

To isolate the exponential term, we can divide both sides of the equation by 1000:

5 = e^(0.12t)

Next, we can take the natural logarithm (ln) of both sides to remove the exponential:

ln(5) = ln(e^(0.12t))

Using the property of logarithms, ln(e^(0.12t)) simplifies to 0.12t:

ln(5) = 0.12t

Now, we can solve for t by dividing both sides by 0.12:

t = ln(5) / 0.12

Using a calculator, we find that ln(5) is approximately 1.6094. Dividing this by 0.12 gives us an approximate value for t:

t ≈ 1.6094 / 0.12 ≈ 13.4117

Rounding to the tenths place, the estimated time it will take for the population to reach 5000 bacteria is approximately 13.4 hours.
