Answer:
a. the segmented body plan of the annelids
Explanation:
lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods. This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life. Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.Answer:

what is hormone injection and subcutaneous implants??
Explanation:
The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.

The active site of an enzyme is damaged, leaving it nonfunctional.
How would this change to the enzyme's function be best described using the graph above?
Choose 1 answer.
The reaction originally proceeded through the path of Y, but now proceeds through the path of
Х.
B
The reaction would continue to proceed through the path of Y.
The reaction originally proceeded through the path of X, but now proceeds through the path
of Y
The reaction would continue to proceed through the path of x
Answer: The reaction originally proceeded through the path of y but now proceeds through the path of X is the answer
Explanation:
Since the enzyme works based on a lock and key model, the reaction will continue through path X (the path of the uncatalyzed reaction).
An enzyme is a biological catalysts that promotes many biochemical reactions in the body. Enzymes are specific. Only a given enzyme can catalyze a particular reaction.
Owing to the fact that enzymes function based on a lock and key model, When active site of an enzyme is damaged, it can no longer fit into its substrate hence, the reaction will continue through path X.

1. There are 2 types of rabbits in a population: those that eat grass, and those that eat flowers and berries. One
year, a drought occurs, and the plants have a hard time producing extras such as flowers or berries. They
can only try and keep themselves green. All year the rabbits have had babies, but many get eaten by
predators like foxes and hawks. Due to the drought, though, many have also starved. Explain what type of
natural selection will occur to this population of rabbits, including what trait is selected FOR and which is
selected AGAINST, and how the population will evolve as a result of the natural selection.
Answer:
Answer:
Against: rabbits that eat berries or flowers
For: grass eating rabbits

Answer:
I'll explain it to make it easier on you :)
Explanation:
This type of natural selection is called disruptive selection. Because of the drought, foxes, hawks, and other animals eating the rabbits, the population of them is being disrupted Think of when a student is being disruptive in class. The teacher usually has to stop the class to 'punish' the student. This situation is similiar. There are things disrupting production and population of the rabbits.
FOR: The population of rabbits
AGAINST: The drought and predators
As a result of disruptive natural selection, the population of rabbits will only decrease due to predators and the drought.

Which organisms are secondary consumers in a temperate coniferous forest?
Complete question:
Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:
moose lynx wolf elkAnswer:
The lynx and the wolf are the only secondary consumers on the list.
Explanation:
In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.
The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.
The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.
On the other hand, the moose and the elk, are both first consumers.
Answer: Wolves
Explanation: Wolves eat primary consumers like rabbits, Lynx are also secondary consumers!

A 50-year-old man became lethargic and drowsy with flushed dry skin after eating a large meal. His family became concerned when he was difficult to rouse, and he had a fruity odor to his breath. He was transported to an emergency facility, where he gave a history of extreme thirst, hunger, and frequent urination. He recently had an upper-respiratory infection that was slow to clear. Adult-onset diabetes mellitus is suspected.
Required:
Which blood test would be ordered?
Answer:
A fasting blood sugar test will be ordered.
Explanation:
A fasting blood sugar test or a glycated hemoglobin test is ordered in such situations. Additionally, tests to determine the insulin level as well as an ophthalmic investigation to determine diabetic retinopathy are ordered. Blood sugar level less than 100 mg/dl is classified as normal. A person is pre-disposed to diabetes if his blood sugar level is between 100-125 mg/dl.
A confirmed case of diabetes mellitus will have a fasting blood sugar level, 126 mg/dl and higher. Insulin administration and a proper management of diet are essential in managing the condition.

A couple receives DNA analysis, which determines that they are both heterozygous for the gene responsible for Tay-Sachs disease. Should doctors or the government have a role in deciding if the couple can have children together? Construct an argument to explain why or why not.
Answer:
The correct answer should be - no doctors or government can not decide if they can have children together or not, it is their personal decision and one can explain complications and consequences only.
Explanation:
Tay-Sachs disease is autosomal recessive disorder it means for the affecting an individual it requires both copy of the affected allele and in heterozygous condition individual act as a carrier and pass the affected gene to next generation. In this case, both parents are heterozygous which means there are 25% chances to have an affected child.
A genetic counselor or doctor can explain the problems parents can have with the affected child and what are the chances of the affected child, however, they can not and should not decide if they both should have children together or not as it is their personal choice and they should be responsible for pro and cons.
The amoeba breaks down food into byproducts and releases usable energy. How is this energy stored most efficiently?
The amoeba breaks down food into byproducts and release usable energy. This energy is stored most efficiently in the form of ATP in cell. Thus, the correct option is B.
What is cellular respiration?Cellular respiration is the process by which cells breakdown complex food materials into simpler byproducts and release energy from it. This process takes place in the mitochondria of cells.
Cellular respiration involves different processes such as glycolysis, citric acid cycle and oxidative phosphorylation of sugars (carbohydrates). Various forms of sugars such as fructose and sucrose are simple carbohydrates. They are the small molecules which can be broken down and absorbed by the body quickly and used as a source of energy.
Therefore, the correct option is B.
