Answer:
one with the largest poplation because they can cook,protect, and get supplies .
Explanation:
In a changing environment, the species which will have the best chances for survival are the one with the biggest genetic variation. Thus, the correct option is C.
What is Genetic variation?Genetic variation is the difference in DNA present among different individuals or the differences between the populations. The multiple sources of genetic variation include mutations and genetic recombination in species. Mutations are the ultimate source of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Variation allows some individuals within a population to adapt better to the changing environmental conditions. Because, the natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation in a population.
Therefore, the correct option is C.

What is the molecule that is formed as a result of the acceptance of hydrogen ion and the final acceptor molecule.
Answer:
Water (H2O)
Explanation:
The final acceptor molecule in the electron transport chain is oxygen. When oxygen accepts hydrogen ions, it forms water. This is why water is released as a byproduct of cellular (aerobic) respiration

Which organism turns nitrogen back into nitrogen gas?
A. denitrifying bacteria
B. nitrogen fixing bacteria
C. decomposers
D. nitrifying bacteria
Answer:
b
Explanation:
part of the nitrogen cycle
Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.
What is nitrogen fixation?Any natural or artificial process called nitrogen fixation causes free nitrogen, a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites.
Chemically, nitrogen fixation transforms atmospheric nitrogen into ammonia, which is ingested by living things.
In essence, nitrogen fixation transforms atmospheric nitrogen into a form that plants can use more easily.
Nitrate is transformed back into nitrogen gas by denitrifying bacteria, which then reenters the atmosphere. Runoff and fertilizer-related nitrogen enters the ocean, where it interacts with marine food webs.
Thus, the correct option is A.

A force of 240 N causes an object to accelerate at 3.2 m/s2. What is the mass of the object?
A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?
Answer:
B.75 kg
Explanation:
Given parameters:
Force on the object = 240N
Acceleration of the object = 3.2m/s²
Unknown:
Mass of the object = ?
Solution:
Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;
Force = mass x acceleration
The unknown here is the mass, simply input the parameters and solve for it;
240 = mass x 3.2
mass = [tex]\frac{240}{3.2}[/tex] = 75kg
The mass of the object is 75kg

Describe an example of acceleration and explain how velocity is changing
The velocity is changing because the acceleration is present which is non-zero.
What is acceleration?The rate of change of velocity of an object in a particular direction is known as acceleration. The acceleration is a vector quantity and its SI unit is a meter per second square. The acceleration is given as,
a = dv / dt
Where dv / dt is known as change.
According to Newton's Second Law, the amount of an element's acceleration is the joint result of two reasons:
The strength of the net resultant force, which is directly proportional to the sum of all external forces exerted on that item;Depending on the components used to create it, an object's mass is inversely related to its magnitude.The velocity is changing because the acceleration is present which is non-zero.

Cellular division
Answer:
Cellular division
Explanation:
it's because abnormal production (mutations) causes leukemia
cellular division is most likely affected by this new drug in case of leukemia. Thus option D is correct.
What is leukemia?Leukemia is a cancer related abnormal division in blood or blood-forming cells. It is other wise known as blood cancer.
The exact cause is not known, major risk factors are radiation exposure, chemotherapy for cancer, smoking, family history of leukemia, and exposure benzene.
Leukemia cells, do not clump to form tumor, due to this leukemia is not diagnosed through imaging tests.
Common symptoms include pain in the bones, swollen lymph,, bleeding and bruising nodes, feeling weak, fevers or night sweats etc.
Leukemias can be acute or chronic.

The diffusion of water molecules in and out of cells is very common.
Which of the following is the process by which water moves across a
membrane, from an area of high concentration to low concentration,
without the use of energy? *
osmosis
hydrolysis
photosynthesis
cyclosis
Osmosis is the process; it is essentially diffusion, which is a spontaneous (no energy input required) process as applied to water.
----------------------------
Hydrolysis is incorrect; that describes a type of chemical reaction in which water breaks a chemical bond.
Photosynthesis is incorrect; that describes the complex process in which energy in light is converted into chemical energy.
Cyclosis is incorrect; that describes the movement of cytoplasm within a cell. There is no spontaneous, net movement of water across a concentration gradient.

eukaryotic cells differ from prokaryotic cells in that eukaryotic cells
Answer:
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον. The domain Eukaryota makes up one of the domains of life in the three-domain system; the two other domains are Bacteria and Archaea. Eukaryotes represent a tiny minority of the number of living organisms; however, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.
Explanation:
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
