Learning through Art: Human Pedigree the genotypes in this human pedigree shown here are homologous chromosomes, gene locus, recessive allele, centromere, sister chromatids, alleles, and dominant allele.
One chromosome from the mother and one from the father are often inherited in a pair. Homologous chromosomes, for instance, are two copies of Chromosome 1 in a cell.
Each gene has two copies, one from each parent, and they are each found at a distinct locus (place on a chromosome). However, the copies are not always the same. Gene copies that differ from one another are referred to as alleles.
When a cell divides, the centromere, which has a similarity with a constrictive area of a chromosome, is crucial in assisting DNA division (mitosis and meiosis). To be more precise, it is the area where the cell's spindle fibers are attached.

A significant shift in the environmental conditions over a very short period of time caused most groups of dinosaurs to become extinct because of their inability to adapt fast enough. This allowed for a variety of niches to open providing current organisms new opportunities. Mammals were one group of organisms that took advantage of this environmental change, filling niches that were unoccupied and eventually developing new species that were specifically adapted to their particular environment. Which of the following is a term that most correctly describes this process?
A. Adaptive radiation
B. Gradualism

Answer the lab question, "What is the effect of the
inheritance of one trait on the inheritance of a
second trait?" with a hypothesis. Remember that
you can either assume that the two genes are
independent or that they are linked. What results
would you expect in either case?
Hypothesis:
DONE
Answer:
Hypothesis: An inherited characteristic is not able to interfere in the inheritance of another characteristic in the same organism.
Explanation:
An inherited feature does not interfere with another inherited feature. This is because the genes are inherited by joining the gametes, which contain the genes of the organism's parents. Each gene is distributed in gametes completely randomly and independently. Inheritable characteristics are represented by these genes. In this way, genes are inherited independently, they do not interfere with inheritable characteristics. However, in genes inherited together, we can consider that only one inheritable trait would be presented, since these genes would interfere in the construction of another trait. This can be studied through hybrid crossings in living beings.

Prozac, Zoloft, and Paxil are called SSRIs because they a decrease the release of oxytocin in the endocrine system in anxiety disorders. b slow the normal reuptake of excess serotonin from synapses in depression. c successfully level the emotional highs and lows of bipolar disorder. d stimulate the release of norepinephrine into the bloodstream in depression. e increase the number of receptor sites for dopamine in schizophrenia.
Answer:
b slow the normal reuptake of excess serotonin from synapses in depression
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Although other neurotransmitters are involved in depression affection, alteration in serotonin levels is an important cause of the disease.
Affected people that express depression show an alteration of the normal serotonin levels in the interneuronal space. There is a noticeable decrease in molecule concentration due to an increase in its reuptake.
The substances used in the depression treatment belong to the SSRI group. SSRI means Serotonin Selective Recapture Inhibitor. It means that these substances inhibit the reuptake of serotonin that usually occurs in affected patients.
ISSR treats depression by enhancing serotonin levels and its transmission by blocking the reuptake in neurons. In this way, there is more serotonin available to improve communication between neurons.
ISSRs are selective because their principal target is the serotonin molecule and not the other neurotransmitters.

Use two examples for plants to explain how the development of new technologies such as radioisotopes has increased our knowlegde of reactions in plants.
Answer: The radioactive isotopes can be used to track many physiological functions and chemical reactions occurring within the cells of the living organisms including plants.
Explanation:
Phosphorus uptake by the plants: Phosphorus is an essential mineral required by the plants for their growth and metabolism. The radioactive phosphorus-32 can be used to track back the rate at which the plant absorbs the phosphorus from the soil. This can help scientists to identify plants that can absorb phosphorus more quickly.
Pesticides levels in the plants: The pesticides levels in the plants can be traced by using radioisotopes such as chlorine-36. This can be used to trace the fact that how much of pesticide is present in the soil and how much of it is utilized by the plants. This is helpful identifying the fact that which pesticide is useful for the growth of the plants.
List the four codes for RNA and show how they are paired.
Answer: adenine (A), uracil (U), guanine (G), and cytosine (C). When this base-pairing happens, RNA uses uracil (yellow) instead of thymine to pair with adenine (green) in the DNA template below.Bases. ... The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine1.

replication has a structure similar to that of remdesivir?
Answer:
RNA nucleotide.
Explanation:
RNA nucleotide is the part of RNA replication that has similar structure to Remdesivir. Remdesivir is covalently bonded to the replicating RNA, which blocks further synthesis of RNA. This Remdesivir work against the viral polymerase and prevents viral spreading by blocking the synthesis of RNA. Remdesivir has similar structure to RNA nucleotide but different in their functions. Remdesivir is used against many viral infections due to its effectiveness on the RNA replication.
Multiple sequence alignment is a method that can be used to compare three or more biological sequences to determine homology and evolutionary relationships between species. This is done by selecting a target protein or DNA sequence (consensus) and comparing it across other species’ sequences. Conservation is a statistical analysis that describes how much the target sequence is observed across the selected group of species. A higher conservation score indicates that the protein or gene is more ancient or more critical across species.

bacteriocytes
phagocytes
complement system
antibodies
Answer:
thx but the answer is D
Explanation:
A pill formulated to attack a specific type of bacteria that infects the throat would best follow the operations of antibodies.
What are antibodies?Antibodies are chemicals produced by the immune system of the body in response to external attacks by foreign substances.
In other words, antibodies are like weapons deployed to defend the body from external attacks.
A pill designed to attack a specific type of bacteria that infects the throat will be most effective if it follows the operations of antibodies.
Since different antibodies are produced for different external invasions, the pill will also be most effective by being specific in its actions.
