Answer:
Explanation:
The immune system is there to develop a strong answer for infections and diseases that can occur in the body. The system is comprised also of gastrointestinal immune cells. These cells secrete lymphocytes that are there to attack whatever is attacking our body. The gut immune cells and the microflora located inside it are responsible for preventing the growth of other microbes that are bad for us in the gut and to fight ingested pathogens that we can get on our food.

An organism's DNA determines the traits it will haveWhich statement correctly explains how DNA determines the organism's traits?
Answer:
This question is incomplete as it lacks options, the options are:
1- The sugar and phosphate groups that make up the backbone are used in different sequences to encode an organism’s traits.
2- The bases A, T, C, and G are always present in equal amounts, so each organism is unique.
3- The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
4- The bases A, T, C, and G are always in the same order in each organism, so each organism is unique.
The answer is 3. The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
Explanation:
Deoxyribonucleic acid (DNA) is the genetic material in the cells of living organisms. It is a polymer biomolecule made up of nucleotides monomers. The DNA contains information that encodes the synthesis of useful products (proteins), which determines the traits in organisms.
A DNA molecule is made up of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). These bases, which are used in different sequences, carry the information that encodes an organism's trait.

what is an important step in the process of translation?
Answer: There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5' end of mRNA. It then moves in the 5' → 3' direction.

Compare and contrast the TWO classes of "seeded "plants.
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.
Why do we need the brazilion forest
Answer:
We need the Brazilian forest because it produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink.
Parelaphostrongylus tenuis is a parasitic brain worm that infects members of the Cervidae family, such as deer and moose. The worm's most common host is the white-tailed deer which lives in

quently in mouse populations. How will the moose populations be impacted by these changes?
Moose populations would decrease as the moose emigrate to safer habitats
Moose populations would increase since the moose and deer can breed creating resistant moose.
Moose populations would decrease as the worm is a biotic factor that will limit the growth of their population
Moose populations would increase as weak moose are killed allowing stronger moose to give birth or immigrate into the area.

Explanation:
Considering the connections between Yellowstone’s wolves, aspen and willow trees, and elk; which one is the keystone species.
Answer:
The keystone species is the wolf.
Explanation:
Every species of organism is important to the ecosystem, so if just one species gets extinct for whatever reason there will be consequences for the other species. How big the consequences will be, depends on the species and on how big of an effect it has on the ecosystem. Some species have relatively small importance, while some have huge importance, and the ones that have huge importance are called keystone species.
The keystone species have such big importance to an ecosystem that with their presence everything is under control, but if they go extinct then the ecosystem suffers badly and changes dramatically. In this case, a keystone species is the wolf. The wolves control the elk population, which in turn means that there is no shortage of food for the elk and they don't damage the young trees. By not damaging the young trees, they grow, so there is a much larger area covered by forest. More forest means less erosion, the water of the streams is better controlled, and there is less meandering. If the wolves are out of the picture, as they were for some time, the picture is totally opposite.
what is a large structure that directs the cell’s activities and contains DNA?
Answer:
That would be the nucleus!
Explanation:
A ball bounces on the ground. How do the ball and the ground act on each other?
Explanation:
It will continue to fall under the influence of gravitational acceleration, but now, a normal force from the ground surface, opposing the force due to gravity, will act on the ball.This all means that the ball is pushing on the ground with a force greater than its own weight, so acceleration must point upward.
The properties of carbon atoms allow carbon to easily bond to other carbon atoms to form _____ and complex macromolecules with unique structures and special functions.
Very Large or
Very Small
The properties of carbon atoms allow carbon to easily bond to other carbon atoms to form very small and complex macromolecules with unique structures and special functions.
What do you mean by Macromolecules?Macromolecules may be defined as biological molecules which carry a large number of atoms in them.
A Carbon atom has the unique ability to form bonds with other atoms of carbon, hydrogen, oxygen, nitrogen, etc. to form small or large and complex molecules.
Therefore, the properties of carbon atoms allow carbon to easily bond to other carbon atoms to form very small and complex macromolecules with unique structures and special functions.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?
Answer:b
Explanation:
The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
How net force will be calculated?
The net force acting on the bicycle is:-
F net = Total force acting on bicycle
In above question,
Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)
So,
Fnet = F1 + F2
Fnet = 150 N -84 N
Fnet = 66 N
Now the acceleration will be
Fnet = mass X acceleration
In above question,
Fnet = 66 N
Mass = 100 Kg
So,
Acceleration = Fnet/Mass
Acceleration = 66/100
Acceleration = 0.66 m/sec^2
Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
