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).What are the issues / concern of cell research list five

Answer:
C.) 2
Explanation:
Just a side note, I just assigned a random letter to work through this problem. It does not matter what you choose.
The carrier genotypes are Aa while any non carriers are AA, and any affected would be aa.
You would go through each of the pairs and do a pedegree to find out the genotypes of the offspring they produce. For 1 it would be a pedegree for Aa from the mom and AA from the dad. There offspring would be 1/2 Aa and 1/2 AA.
For number 2 it would be Aa for the mom and Aa for the dad. There offspring would be 1/4 AA, 1/2 Aa, and 1/4 aa.
For number 3 the mom would have AA and the dad would be aa. There offspring would be 4/4 Aa
For number 4 the mom would be Aa and the dad would be AA. There offspring would be 1/2 AA and 1/2 Aa.
Group #2 are the only set of parents that would produce a offspring that would be affected by the genetic condition, so the answer is C

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.

Explanation:
took test (k-12 student)
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.

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).

As a result of the general stress response, blood concentrations of epinephrine.
Answer:
THE STRESS RESPONSE. Increased concentrations of cortisol, glucagon, and epinephrine serve to increase blood glucose levels and to redirect metabolism so as to increase concentrations of fuel substrates. Finally, there appears to be a tendency towards hypercoagulability, which would likely improve hemostasis.
Explanation:
Dose this help you?
As a result of the general stress response, blood concentrations of epinephrine and cortisol rise.
What metabolic changes occur during the stress response?When the body is under stress, the hormone cortisol, stress and steroid, is released. As a result, the body's sugar level rises, and the extra sugar aids in tissue healing.
Adrenaline is another name for epinephrine. It is a hormone used in medication. When the body experiences an emergency, this is released. When something unexpected happens, like getting stung or bitten by a dog, taking medicine, etc.
They come with charges that include faster heartbeats, higher blood sugar, and improved accuracy.
Therefore, blood concentrations of epinephrine and cortisol increase during the stress response.

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.
