Answer:

Explanation:
Please correct me if im wrong
The endocrine system generally uses negative feedback to maintain homeostasis. true.
The endocrine systemThe endocrine system has the function of coordinating and integrating the activity of cells throughout the organism by regulating cellular and organic functions and by maintaining homeostasis (maintenance of a constant internal environment) throughout life.
Negative feedback is one of the most important mechanisms for maintaining our body's homeostasis, that is, for internal balance. This mechanism guarantees an opposite change in relation to the initial alteration, that is, it produces responses that reduce the initial stimulus.
Whit this information, we can conclude that the endocrine system generally uses negative feedback to maintain homeostasis.

B. humans and other multicellular organisms that are about the same size as humans
C. plants and animals that are smaller than humans but still visible
D. organisms that are microscopically small and each made of a single cell
Answers
humans and other multicellular organisms that are about the same size as humans.
What are 6 kindgoms?
The greatest classification for all organisms in biological taxonomy is called a kingdom. In taxonomy, there are 6 kingdoms. These six kingdoms comprise all forms of life. Eubacteria, Archae, Protista, Fungi, Plantae, and Animalia are the six kingdoms.
Most scientists believed that all living things could be categorized as either plants or animals up until the 20th century. However, most biologists realized in the 1950s and 1960s that this approach was insufficient for fungus, protists, and bacteria.
A classification scheme known as the "Five Kingdoms" came to be acknowledged as the standard by which all living things may be arranged by the 1970s.
Therefore, humans and other multicellular organisms that are about the same size as humans.

I need a Multiple Alleles trait for an animal!!!
Answers
Answer:
Fury can be a allele trait in an animal anything that you can see in the physical appearance on the animal can be a alleles trait
Answer:
Anything you see physically on an organism can be considered as an allele.
Explanation:
An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Let's use one example: a white bunny with red eyes. One allele for this animal would be that it has white fur color. Another allele would be its red eye color.
Let's use another example, but with two people. Person A has straight hair and freckles. Person B has curly hair and no freckles. Person A's alleles would be straight hair and freckles. Person B's alleles would be curly hair and no freckles.
Any physical characteristic trait on an organism can be considered as an allele for that organism.

Starvation, suffocation, and dehydration are all root causes of death in human beings. Dehydration can take 3-10+ days, starvation can happen in weeks to months, and suffocation occurs in a manner of minutes. How do these processes negatively impact homeostasis so severely that they cause death? Why is there such a discrepancy in the time involved? How are these processes all connected?
Answers
Answer:
Starvation, suffocation, and dehydration takes different time to death of human.
Explanation:
Starvation takes more time to put the human into death because there are reserves of food in our body which can be used by our body in order to survive when these reserves ends up, the human die. In suffocation, human die in less time because oxygen is needed by our body to produce energy for doing activities so if there is no oxygen leads to no energy so the cells die, while on the other hand, dehydration also takes less time to starvation because our body need water to remain turgor and for the circulation of blood in the body if there is no water, no circulation occurs that leads to death.

Although the number of genes in the human genome is surprisingly low compared to less complex organisms, the number of possible products from those genes is greatly amplified by _____.a. coordinate control of genes on different chromosomesb. alternate arrangements of exons from a primary transcriptc. differential activation of genes in different cell typesd. each gene being activated by a unique combination of control elements and activator moleculese. the congregation in specific sites in the nucleus of genes involved in related metabolic processes, but on different chromosomes
Answers
Answer:
alternate arrangements of exons from a primary transcription.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Although, the number of genes contained in the human genome is surprisingly low in comparison with less complex organisms such as bacteria, protozoa, salmonella, etc.
However, the number of possible products from those genes is greatly amplified by alternate arrangements of exons from a primary transcription.
An exon refers to the coding portion of a gene that contains the information required for transcribing and translating (encoding) the final part of a mature RNA, after one or more DNA sequences (introns).
Simply stated, an exon is a nucleotide sequence in DNA and RNA used for encoding a part of the final mature RNA.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
