Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.

Why are dark colored pocket mice found in the dark, rocky areas of the desert?
their fur is that color so they can camoflaugue with their surroundings
Answer:
Because God put them there on purpose. For example, they could hide in little tunnels in the ground to hide from predators, and also, so it could camoflauge with it's surroundings. Have a great day!

Explain the relationships and trade-offs among amounts of skin pigmentation, Vitamin D production, and protection from UV radiation.
Answer:
Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D
Explanation:
Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.
compare and contrast the processes of mitosis (asexual reproduction) and meiosis (sexual reproduction).
Answer:
Diffrence:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

What data provides the strongest evidence (most valid) that early Earth conditions provided what was necessary for life?
A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.
Answer:
A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.
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.

Nabeel is trying to determine whether the slope of the ground affects the growth rates of plants. He just finished taking measurements of plant heights in various locations over a period of time. Now, he is starting to compare his measurements and look for patterns. Which step of the scientific method is Nabeel on?
Answer:
Experiment
Explanation:
Scientific methods includes the step by step procedures in science of solving problems.
It has four basic steps this include, Characterizations which is the observations, definitions, and measurements of the subject that is involved in the research.
Hypotheses is formulated which is the theoretical explanations of the problems to be solved.
Predictions are made from the hypothesis formulated and
Experiments which is done to validate the hypothesis. It includes DAT collection, data analysis, interpretation of results. Nabeel is at the experiment stage where he is collecting data on plant and comparing the data so he can make inference that can help validate his hypothesis.

What is speciation ? List four factors that could lead to speciation. Which of tjese cannot be a major factor in the speciation of a self-pollinating plant species? Explain. Give reason to justify your answer.
pesto ica está.
➜ Speciation is the formation of new species from the pre-existing population.
Factors responsible for speciation:
Genetic drift. Natural selection.Geographical isolation. Mutation.Geographical isolation cannot be a major factor in the speciation of a self-pollinating plant species because physical barrier cannot be created in self-pollinating plants.
Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
