Explanation:
Thanks OP for answering your own question!
The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.
What are genetic comparisons in evolution?Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.
Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

Termites are unable to digest some plant materials (fiber). Termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
commensalism
mutualism
parasitism
competition
The relationship between the termite and bacteria is called mutualism.
What is mutualism?Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.
According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.

The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.
What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.
Therefore, the correct option is B.

what is made when a sperm cell combines with the polar nuclei?
Answer:
Explanation:Two of the nuclei (the polar nuclei) move to the center of the embryo sac and fuse together, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm, which will ultimately provide nourishment for the developing embryo (analogous to yolk in animal eggs).
Answer:
endosperm
Explanation:
The second fertilization results in the endosperm, which is a special tissue used to nourish the embryo.

Which theory of development do you prefer: Piaget or Erikson's stages? Why?
Answer:
Differences between Piaget and Erikson
Alternatively, Piaget examined the thought process of the child and how their brain responded to the environmental factors around them, rather than just crises. While Piaget focused on cognitive development, Erikson's thoughts were more focused on emotional development.
Explanation:
please give me brainlist and follow
Answer:
*This was my answer* the sections are actually really interesting if you read them.
I prefer Erikson's stage of development because Erickson really goes in-depth about each stage of life and how the challenges faced in those stages have a huge impact on human development. I also appreciate that he includes what would happen if those challenges weren't faced and how that could affect that person's future in the long run.
What characteristics do all living things share?
A: They contain DNA
B: They are made up of many parts
C: They reproduce by mitosis
D: They need oxygen to survive
Sea stars can reproduce sexually and asexually. In sexual reproduction, fertilization
occurs in the water with males and females releasing sperm and eggs into the
environment.
Asexual reproduction is by fragmentation, a part of an arm and part of the central
disk becomes detached from the "parent" and develops into an independent
individual sea star. In the past, many sea stars have been "killed" by chopping them
into pieces but they have been able to regenerate and grow into more sea stars. This
happend on the Great Barrier Reef in early attempts to control the Crown of Thorn
Sea stars.

Answer: 0.5
Explanation:
Number of people with traits = 900
Total number of individuals= 1800
To find the probability with regards to the question, we divide the number of individuals having the traits by the total population of individuals. This will be:
= 900 / 1800
= 0.5

Using the second picture below,label the x-axis ‘‘Year of Study’’.Label the x-axis with data listed in the first picture.(pls make sure that the grid your using is same as picture two below)
Based on the sizes of the numbers for each population, create a scale on the two separate y-axes. The snowshoe hare population ranges in size from 5000 to 95000. Label the y-axis on the left side of the x-axis as “Hare population (in thousands)." Number this y-axis from 0 to 100, in intervals of 10. The lynx population ranges in size from 500 to 6000. Label the y-axis on the right side of the x-axis as "Lynx population (in thousands)." Number this y-axis from 0 to 10, in intervals of 1.

15. Normally, tumor suppressor genes inhibit the cell cycle. How do mutated tumor suppressor genes affect the
cell cycle?
Answer:
Abnormal growth of cells.
Explanation:
Mutated tumor suppressor genes result in a loss or reduction in cell function, causing the cell to grow abnormally.
Tumor suppressor genes are the genes that regulated the cell cycle and cell division. The mutated tumor suppressor genes lead to abnormal cell growth and cancers.
What are tumor suppressor genes?Tumor suppressor genes are the anti-oncogene that regulates the cell cycle and replication. MADR-2, APC, and p-53 are the tumor suppressor genes that produce proteins that regulate the growth of the cell and cell division.
The mutation in tumor suppressor genes leads to loss of the function of suppressing abnormal cell growth resulting in tumors and cancers. This list is due to an increase in the proliferation of the cells that leads to loss of cell function showing contact inhibition.
Therefore, a mutation in the tumor suppressor genes leads to uncontrolled cell growth.
