What evidence that supports Darwin theory of evolution was not known until after he died
Answer:
The term "genetics" wasn't even coined until 1905, long after Darwin's death in 1882. And though the first fossil recognized as an ancient human—dubbed Neanderthal Man—was discovered in Germany just before Origin was published, he could not have known about the broad and varied family tree of ancestral humans.

Water is a polar molecule because?
A. It has a charge
B. It does not have a charge
C. Contains two hydrogen atoms for each oxygen atom
D. Different parts of the molecule have slightly different charged
Answer:
D. Different parts of the molecule have slightly different charges
Explanation:
Water is a polar molecule because different areas of the molecule have different and opposite charges
Oxygen has a higher electronegativity than hydrogen, which means the electrons of the water molecule will stay closer to the oxygen than the hydrogen.
This creates an uneven distribution where the oxygen has a partial negative charge and the hydrogen has a partial positive charge.
So, D is the correct answer.
which process converts light energy to chemical energy to form food
Answer:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

which graph best represents the percentage of lighted Side of the Moon that can be seen by an observer in the northern hemisphere when the moon is at the position shown
Answer:
4
Explanation:
The graph that represents the percentage of lighted side of the moon is ; ( 4 ) i.e. The fourth graph .
Given that the observer is stationed at the Northern Hemisphere, as the moon orbits around the sun following a parabolic path, the observer will observe a fully lighted moon ( i.e. 100% ) when the moon get to the center of its parabolic path because at this position the earth cannot cast a shadow on any part of the moon.
Hence we can conclude that the graph that represents the percentage of the lighted side of the moon is Graph 4

Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parental hyphae. What is the BEST explanation for this observation?
A.
The spores inherit half their genes from each parent.
B.
The spores inherit haploid nuclei from their parents.
C.
The spores inherit mutations as a result of meiosis.
D.
The spores inherit mutations as a result of mitosis.
Answer:
A
Explanation:
The correct answer would be that the spores inherit half of their genes from each parent.
The ascospores start their journey through the fusion of 2 haploid nuclei (karyogamy) to form a diploid zygote nucleus. The zygote nucleus develops and then divides by meiosis to produce 4 haploid daughter cells. Each daughter cell then divides mitotically, making it eight haploid nuclei at the end.
Hence, each spore inherits half of its gene from different nuclei.
The correct option is A.
Answer:
A. The spores inherit half their genes from each parent.

Explanation:
Cellular contact inhibition is important in wound healing.
What is contact inhibition?Contact inhibition is the process whereby a normal cell's unchecked proliferation is inhibited as a result of its contact with neighboring cells.
What is wound healing?The process by which a living creature replaces lost or injured tissue with newly formed tissue is known as wound healing.
What happens when contact inhibition is lost?When this property is lost the cells undergo uncontrolled division and they form cancerous growth.

What is the sexual reproduction process of angiosperms?
Answer:fertilization
Explanation:
Answer: Sexual reproduction occurs in three stages: pollination, fertilization, and dispersal. During pollination, pollen is transferred from the anther to the stigma. Once the pollen is stuck to the stigma, it produces a pollen tube that grows down the style to the ovary and into the ovule. A sperm cell then travels down the pollen tube into the ovule and fertilizes the egg cell. The fertilized egg is called a zygote. This zygote grows into a plant embryo. The embryo is located inside the seed along with the seed coat and stored food. The ovule develops into the seed. The ovary develops into the fruit that protects the seed. The fruit also helps disperse the seed. Seeds are dispersed, or spread, to new locations, where they grow into seedlings. or pollen is taken to the stigma. i took the test
The depolarization of the ____________ normally generates the action potential that leads to depolarization of all other cardiac muscle cells.
Answer:
The depolarization of the ___SOMA NEURONAL_________ normally generates the action potential that leads to the depolarization of all other cells of the heart muscle.
Explanation:
The depolarization of the neuronal body, that is, the body of the neuron, generates an action potential that is transported throughout the axon, until in the motor unit (union between neuron and muscle) the action potential is transmitted to the cardiac cell, depolarizing the membrane of the myocardial cell and thus effecting cardiac contraction.
Cardiac contraction occurs in a controlled, rhythmic and systematic manner, with autonomic character and as a consequence of the release of calcium from REL to LIC
Which of the following are examples of active transport that cells use to maintain homeostasis? (mark all that apply)
Pinocytosis and phagocytosis are examples of active transport that cells use to maintain homeostasis, hence option A and C are correct.
What is homeostasis?The propensity to oppose change in order to preserve a stable, largely constant internal environment is known as homeostasis. Negative feedback loops are frequently used in homeostasis to combat deviations from set positions in a variety of properties.
Moving uphill is considered active transportation. A cell must expend energy to transport materials against a concentration or electrochemical gradient.
This is precisely what active transport systems do they use energy, frequently in the form of ATP, to keep the proper concentrations of ions and molecules in living cells.
Therefore, option A and C are correct.

After an earthquake, a small group of beetles from a much larger population becomes trapped in a cave. They are able to persist (continue living and reproducing) in the cave, but they cannot migrate back to the source population outside the cave. What would most likely result from this scenario
Answer:
They will evolve into a new species
Explanation:
The most likely result from this scenario is that the now isolated group of beetles will evolve and become a new beetle species that is unique from the old population.
The beetles have become geographically isolated from the original population and this makes them become a new species through the process of allopatric speciation. Allopatric speciation is an evolutionary mechanism of species formation as a result of being geographically separated from the old population. It is as opposed to sympatric speciation in which a new species is formed within a population of species without being geographically barred from the original population.
The fact that the isolated species are now in an environment that is different from that of the original population means that they will take a different route to evolve in terms of trying to adapt to the changes that would be occurring in their environment.

Among the three types of protists, which one produces spores?
Protozoa
Ciliates
Red algae
Slime molds
The spore-producing protists amongst the given answers are red algae, i.e., option C.
What are spores?Spores are reproductive cells that protists and other organisms produce. When two protist spores come into contact, they can fuse to form a diploid zygote. The zygote then goes through meiosis, producing haploid cells that continue the cycle.
Red algae reproduce both sexually and asexually. Asexual reproduction can occur via spore production as well as vegetative reproduction.
