What happens when an antibody and antigen react?
Answer:
Antigen-antibody interaction, or antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction. The immune complex is then transported to cellular systems where it can be destroyed or deactivated.
Explanation:
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of
Answer:
absorption and circulation
Explanation:
While digestive enzymes are produced in numerous parts of the digestive system, the pancreas produces the majority of them.
What is the important role of metabolism in digestive tract?In the digestive tract, digestion and absorption take place. All body cells may access the nutrients after they are absorbed, and the cells use them for metabolism.
The six actions, or functions, of the digestive system prepare nutrients for use by body cells.
The gastrointestinal tract, which was previously mentioned in this study, is a specialized sensory system.
In charge of detecting ingested glucose and relaying information to peripheral tissues or the brain to control glucose metabolism.
Therefore, In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of absorption and circulation.

Which of the following is true about natural selection? Choose 1 answer:
Answer:
It can only act on traits that are heritable and show variation.
Explanation:
For natural selection to act on a trait, there must already be variation for that trait. In addition, the trait must be heritable, or able to be passed from parent to offspring.

Why do you think
organisms in the
same kingdom are
not all identical?
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
Though they are in the same kingdom which makes them makes the species they are built of different genes received from each parent.

All Hawaiian honeycreeper bird species have similar skeletal and muscle structures. However, each Hawaiian honeycreeper species has a bill specialized for eating certain foods. What would a scientist most likely conclude based on this observation? Artificial selection shaped the bill for eating certain foods. Increased genetic variation resulted in similar skeletal and muscle structure. Changes in each honeycreeper species occurred independently, but resulted in similar traits. Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.

In your own words, describe the base-pairing rules in any DNA molecule (Hint: Think about the BFF's)
Answer:
There are four different bases, each of which pairs with only another. Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C). This rule is universal to all DNA. A good way to remember is apples in the tree (adenine and thymine), cars in the garage (cytosine and guanine) (credit to the Amoeba Sisters)
Which of the following is involved in the opening of stomata for the gas exchange of the plant?
Answer: Osmotic Pressure, lb/in2
Explanation:
Osmotic pressure is involved in the opening of stomata for the gas exchange of the plant.
What are stomata?In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Transpiration and gas exchange is made possible by stomata. It is surrounded by two guard cells that regulate how the stomata open and close. Stomata open during the day for gaseous exchange and to release water vapour during transpiration. The stomata open and close in response to changes in the turgor pressure within the guard cell.
Hence, osmotic pressure is responsible for the opening and closing of stomata.

Refer to the given strand of DNA: CTG ACG GCC ACC
1. Which of the following mRNA triplets compliments ACC?
a. GAC c. UGC
b. CGG d. UGG
2. What process was involved in number 1?
a. Fertilization b. Replication
C. Transcription d. Translation
Answer:
d
Explanation:
a goes with u
c goes with g
The mRNA triplets compliments ACC is UGG and the process involved is transcription.
DNA transcription
DNA transcription is a process carried out by messenger RNA, which has as its ultimate goal the formation of proteins.
This transcription occurs with the combination of nitrogenous bases, which combine in such a way:
C - G
G - C
A - U
T - A
So, the transcription of the ACC base would be equivalent to UGG, and the process is called transcription.
