If a population is already well-adapted to its environment, will most mutations be helpful or harmful? Explain.
Most mutations will be helpful if a population is already well-adapted to its environment.
What is Mutation?This is defined as a change in the DNA sequence of organisms. These changes occur as a result of the ever changing environmental conditions.
When there is a high adaptability by the population, then it infers that the mutation is a helpful one.

Answer:
B i think or C
Explanation:
Because in the way I am thinking it's B, "School cooks should be educated on allergies to peanuts." It makes the most sense
Answer: b
Explanation:
it can't be a since source 2 says "few people recognize..." which contradicts "students know what to do..."
it can't be c because there is no source comparing peanut allergies now vs. past.
it can't be d because you cannot infer this from the given data.
leaving us with b because since a majority of peanut allergies happen at school and not many know how to deal with an event with a peanut allergy, then teaching cooks about peanut allergies will help students in the case of an allergic reaction in school.

If nondisjunction occurs during meiosis I, how many of the daughter cells will have an incorrect number of chromosomes after meiosis I and meiosis II are complete
If nondisjunction occurs during meiosis I, then four (4) daughter cells will have an incorrect number of chromosomes after meiosis.
What is non-disjunction?Non-disjunction refers to the faulty separation of chromosomes during cell division (either meiosis or mitosis).
Meiosis is a cell division that produces four daughter cells having half of the genetic material of the parental cell.
Non-disjunction in meiosis I is known to cause an imbalance in all daughter cells (i.e., in 4 daughter cells).

A student is investigating the strength of electromagnets she created using batteries, wire, and nails.
She uses two different-sized nails and varies the number of coils of wire around the nail to determine how many paper clips each configuration can lift. She makes a data table of the results.
The student hypothesizes that the number of coils has a cause-and-effect relationship on the strength of the magnetic devices she made. Which would be the best way for the student to test the devices to be sure that her hypothesis is accurate?
Explanation:
You will change two variables to make different electromagnets: the number of wire coils around the nail (10 or 20) and the number of D cell batteries.

Why is cellulose important for explaining how carbon atoms get "locked up" (stored) in a tree as long as it is alive?
O Cellulose is what is produced in photosynthesis.
O Cellulose is used to make new cell walls, when tree cells divide, which become part of the tree.
O Cellulose is made up of CO2 molecules from the atmosphere that stay in the tree.
O Cellulose is what the trees use to make starch, which stores energy for the tree to use later.
Cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.
What is cellulose?It is a biopolymer, that is, a long chain of carbohydrates, composed exclusively of glucose molecules (β-glucose) linked together by hydrogen bonds.
It is synthesized by the photosynthesis of plants and whose main function in plant tissues is support, that is, it is part of the cell wall of plant cells.
Therefore, we can conclude that cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.

What prior species of hominids did homo sapiens encounter in europe approximately 40,000 years ago?.
Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

Answer:
Mark me brainliest please I really need itExplanation:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually chamge over time.Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.Evidence that supports the theory of evolution are fossils, embryological studies, anatomical and morphological characteristics (homologous organs, analogous organs, vestigial organs), molecular biology (comparing DNA sequences).Which of the following are examples of habitats where sympatric speciation could occur?
