Answer: Natural Selection. Natural Selection leads to an evolutionary change when some individuals with certain traits in a population have a higher survival and reproductive rate than others and pass on these inheritable genetic features to their offspring.
Explanation:
which of the following is a complementary base pair ?
A . guanine - thymine
B . guanine - guanine
C . adenine - cytosine
D . guanine - cytosine
Answer:
D is the anwser
Explanation:
I took the test and the answer was Guanine and cytosine!
A complementary base pair in DNA is guanine-cytosine (Option C).
The deoxyribonucleic acid (DNA) molecule is a double helix composed of two long (polynucleotide) opposite chains that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each having one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).
According to the base pair rules, Guanine always pairs with Cytosine by three hydrogen bonds, whereas Thymine always pairs with Adenine by two hydrogen bonds.
In conclusion, a complementary base pair in DNA is guanine-cytosine (Option C).

How do stressed corals respond to disease?
Answer:
Much of the time, microorganisms as of now exist in the wild, and as corals become focused from human as well as common unsettling influences, their safe framework is debilitated and they are thusly more defenseless to illness.
Explanation:
Answer:
Brainliest pls!
Explanation:
In many cases, pathogens already exist in the wild, and as corals become stressed from human and/or natural disturbances, their immune system is weakened and they are therefore more susceptible to disease.
Why do continents rise above the ocean floor?
Answer:
This increase is linked to the continental crusts rising above the oceans. ... As Earth's land plates began to shift and move, less dense rock may have been forced upward, shaping the continents we see today on Earth's crust.
Explanation:
Answer:
the second one
Explanation:
As a result, the rock that forms from that melt is less dense than the original rock.

Answer:

Cellular Respiration: Mitochondrion: Animals
Avanços no conhecimento científico levantaram dúvidas sobre as ideias da criação divina e do surgimento da vida por mecanismos não reprodutivos. Em meados do século XIX, experimentos científicos ocasionaram alterações no entendimento sobre a origem dos seres vivos. Marque a alternativa que contempla o experimento que forneceu evidências irrefutáveis de que os seres vivos surgem somente pela reprodução de seres da mesma espécie.
Answer:
Tiger with lion.
Explanation:
Living beings arise only through the reproduction of beings of the same species. For example, tiger did not mate with lion because both are different species. Tiger can mate with their female tiger and produce fertile offspring while the lion only mate with their female lion and produces fertile offspring which belongs to the same species so we can conclude from this discussion that living beings formed only reproduction of same species.
Name two other subcellular structures that can be found in an animal cell.
1. ......
2. .......
Answer:
Any two other subcellular structures that can be found in an animal cell are:
nucleus.
mitochondria
The two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.
An animal cell is a type of eukaryotic cell which lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles which are present.Animal cells range in size from a few microscopic microns to a few millimetres.
Animal cells are eukaryotic cells with a membrane-bound nucleus. Furthermore, these cells exhibit the presence of DNA inside the nucleus. They also comprise other membrane-bound organelles and cellular structures that carry out specific functions necessary for a cell to function properly.
A nucleus is defined as a double-membraned eukaryotic cell organelle that contains the genetic material.It contains the cell’s hereditary information and controls the cell’s growth and reproduction.
The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.
A mitochondrion is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.
Thus, two other subcellular structures that can be found in an animal cell are nucleus and mitochondria.

Consider a population of 100 fox squirrels. The population is increasing exponentially, by a rate of 30% each year. If this rate continues, how many fox squirrels will there be in this population after two years?
Answer:
Future population = 169 squirrels
Explanation:
Given:
Current population = 100
Rate of growth = 30 % = 0.30
Time = 2 year
Find:
Future population
Computation:
Future population = 100(1+0.30)²
Future population = 100(1.30)²
Future population = 100(1.30)²
Future population = 169 squirrels
From the information that two atoms have two different proton counts, you can conclude that the atoms _____.
a - belong to two entirely different elements
b - represent different isotopes of one element
c - are likely to react violently with each other
d - might be different ions of the same element
Taking into account the constitution of an atom and the definition of atomic number, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.
AtomAn atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
Every atom consists of a nucleus in which neutrons and protons meet and energy levels where electrons are located.
In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.
Atomic numberAtoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom.
This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. Then it is possible to say that the atomic number Z determines its identity.
This caseFinally, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.
