Answer:
D. ability to survive
"The central concept of natural selection is the evolutionary fitness of an organism. Fitness is measured by an organism's ability to survive and reproduce, which determines the size of its genetic contribution to the next generation."
Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.
What is Fitness?Fitness may be defined as the situation of survivability of an organism under a given condition.
It is the concept of natural selection that it is only the relative fitness that estimates the existence or extinction of species in a particular habitat.
The Relative fitness of an organism overall depends on relative survival and relative reproduction.
Therefore, Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.

Which of the following is not a functional group that can bond with carbon?
а
carbonyl

phosphate
Sodium is not a functional group that can bond with carbon (Option C)
A functional group is a combination of atoms in a molecule that is capable of conferring particular chemical and physical properties.The most common functional groups include the carboxylic acids groups (CO2H), carbonyl groups (C=O), alcohol groups (-OH), ester groups (CO2R), and amine groups (NH2).Functional groups are observed along the carbon backbone of the biomolecules.This carbon backbone is made up of chains/rings of carbon atoms with the occasional substitution of an element (e.g., N or O).Learn more in:

As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

which orgnaisms transform nitrogen to a form that is useful to plants
Answer:
Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
Explanation:
Answer:
Nitrogen fixing bacteria
Explanation:
Atmospheric nitrogen is in the form of
N
2
. This molecule is exceptionally stable and unable to be used by plants. The Lewis dot structure of
N
2
is
: N :::N:
The triple bond between the two nitrogens is very strong. However nitrogen fixing bacteria can attach to the the unused paired electrons on the outside of the nitrogen molecule. The bacteria use the energy from the broken bond for life functions and produce Nitrates and Nitrites as by products. Nitrates (
N
O
3
) and nitrites (
N
O
2
) can be used by plants for nutrition.

How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.

In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
Which of the following conclusions is most likely to be CORRECT?
A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

Answer:
Science Question: When the plant is exposed to light for longer periods of time, it's height increases more than those plants that weren't exposed to light for as long.
Control: I think the control would be a plant that was exposed to light for 24 hours (all day). Not completely sure, but that's what i would say. (If you aren't sure what a control is, it's just a sample that you don't change at all. It's used to compare other samples' results.)

The brain stem consists of the ________. Group of answer choices midbrain, medulla, and pons cerebrum, pons, midbrain, and medulla midbrain only pons, medulla, cerebellum, and midbrain
Hey there! I'm happy to help!
The cerebellum is in the back of the brain and it helps with balance and reflexes, but it isn't part of the actual brain stem, so that is not the right answer choice.
The cerebrum is the front part of the brain made up of the many different lobes. Its ultimate goal is to help with thought, movement, and language. This is not part of the brain stem.
The brain stem consists of the midbrain, medulla, and pons. The midbrain is the uppermost part with the pons below it and the medulla oblongata below the pons.
The midbrain is important for functions such as eye and body movement. The pons aids with body signaling and the medulla oblongata also aids with reflexes and involuntary actions (as it is close to the cerebellum). The brain stem as a whole helps with respiration, heart rate, and blood pressure.
