which parts of the monomers involved in the dimer formation
Answer:
A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).
helper t cells secrete ________ to stimulate the proliferation of b cells.
Answer:
Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.
Helper T cells secrete cytokines to stimulate the proliferation of B cells.
What are Helper T- Cells?Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.
Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.
They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

Describe prokaryotic cells. Include general characteristics and indicate the one feature that eukaryotic cells have that prokaryotic cells do not.
Please no links!
Answer:
prokaryotic cells — e.g. Bacteria
eukaryotic cells — e.g. Animal/Plant cells
Prokaryotic Cells are unicellular organisms that don’t have a nucleus, but have their DNA unbound (or uncompressed) within the cells cytoplasm, they also have circular structures (or rings) called plasmids which carry additional Genetic Information.
Specific Example: A bacterium is an example of a prokaryotic cell, and it has a cell wall, cell membrane, and even a capsule.
One feature that Eukaryotic cells have which Prokaryotic cells don’t is a Vacuole (this is just one feature).
Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and don’t have organelles. Many also have a capsule or slime layer made of polysaccharide (ignore this word if you havent learn about it yet).

How does a mutating virus impact vaccinations? What would happen to the effectiveness of the current vaccination if a mutation in the virus caused the protein spike to change?
A vaccine is a medical product. Vaccines, though they are designed to protect from disease, can cause side effects, just as any medication can. When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes. Most viral mutations have little to no impact on the virus’s ability to cause infections and disease.

Why is it important that mitosis occurs like this
Answer: The cell divides upon these processes during a process known as mitosis. In mitosis, two daughter cells are formed. It is important that each of the daughter cells contain genetic information that is identical to that of the mother cell, as well as that there be no mutations. Mitosis is Important for three main things:
> Growth
> Repair
> Reproduction

Explanation:
describe the path that oxygen travels when you breathe.
Answer:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

How to read a pedigree.
Answer:
Explanation:
One trick for identifying a recessive trait is that if a trait skips a generation in a pedigree, it is often an autosomal recessive trait (although a trait can be autosomal recessive and not skip generations). These traits appear with equal frequency in both sexes.
A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.
Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.
WHAT IS ACTIVE TRANSPORT?Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.
This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

what determines how closely related 2 species are?
Answer:
Before: (Darwin did) Physical features and behavior
Now:
DNA Testing
Explanation:
Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are. However, now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive. One example of looks being deceptive is: The bat and the crow both have wings, and the squirrel does not. From this, one may think that bats and crows are more closely related than bats and squirrels, while the opposite is indeed the case.

which receptors respond to stimuli within the body?
Answer:
Sensory receptors respond to stimuli.
Explanation:
They can be classified by their location, the type of stimulus they detect or by their structural complexity.
Sensory receptors are the receptors which respond to stimuli within the
body. The body have five major sensory organs which include the eyes,
nose, tongue, ear and skin.
These organs have receptors which is responsible in the transmission of
signal to the brain for action. The brain acts depending on the signal
received which is usually in the body's best interest.
This makes our sensory organs important and very delicate and as a result

termination of transcription in bacteria occurs when ________.
Transcription is the process of synthesizing the RNA transcript from DNA.
The termination of transcription in bacteria occurs when RNA polymerase comes in contact with some particular terminator sequences that stalls the RNA polymerase letting it fall off.
In transcription, there is its initiation (start) and its termination (and end). Unlike humans with stop codons that terminates the process, the bacteria uses a terminator sequence which it transcribes and cause its fall off the DNA and releasing the RNA transcript.Learn more about transcription in bacteria: https://brainly.com/question/25408927

The following images are shown in this diagram:
A T-Rex dinosaurA drawing of the planet EarthA drawing of grassA drawing of a cowA drawing of a humanThese 5 pictures can be related to finding the main message of the diagram. This diagram can be interpreted as the evolution of species on planet Earth because a dinosaur is shown first, a species that lived millions of years ago.
An image of the Earth is then displayed showing the familiar shape of the continents to demonstrate evolution on the Earth's surface.
Then show the grass because this represents the evolution of plant species that were expanding throughout most of the Earth.
Subsequently, a cow is shown as an example of the mammalian animals that exist today and finally the human who is the product of various evolutionary processes that resulted in the society and the world that we know today.
