how many amino acid hormones what are
Answer:
Amino Acid Derivatives
There are two groups of hormones derived from the amino acid tyrosine: Thyroid hormones are basically a "double" tyrosine with the critical incorporation of 3 or 4 iodine atoms. Catecholamines include epinephrine and norepinephrine, which are used as both hormones and neurotransmitter

Why would your force of gravity increase if you went to a larger planet?
Answer:
Objects with more mass have more gravity.
The chemical bond between amino acids is called a bond.
Answer:
Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
The chemical bond between amino acids is called a peptide bonds.
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction) and usually occurs between amino acids.
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of neighboring amino acids.

DNA is bound into this shape for storage and replication before mitosis.
chromosomes
Triangles
Circles
Ovals
Answer:
chromosomes
Explanation:
Deoxyribonucleic acid, also known as, DNA, is the genetic material in living cells that stores genetic information. However, DNA is supercoiled around certain proteins called HISTONES into an X-shaped threadlike structure called CHROMOSOMES.
Chromosomes are the forms in which DNA is stored and undergoes replication in the nucleus (eukaryotic cells) or nucleoid (prokaryotic cells).

Juan and billy hooked a science book on the end of this spring scale. What is the force of gravity pulling down on the books?
A) 23 grams
B) 2300 grams
C) 23 Newton’s
D) you cannot determine the force of gravity
Answer:
D) you cannot determine the force of gravity
Explanation:
Answer:
23 Newtons
Explanation:
Well, the type of measurement that is being used is called Newton. So that eliminates A and B. You can determine the force of gravity, that's pretty much common sense, Therefor the Answer is C.
Whatstatement accurately names and describes the function of the organelle labeled B?
The correct answer is Option A .
Organelle B = Mitochondrion.
A mitochondrion converts food into energy for cellular functions.
Explain functions of mitochondrion?According to the diagram, the organelle labelled A absorbs solar light energy and transfers it to the mitochondria ( organelle labelled B )The energy that the mitochondrion receives is put to use by the organelle to break down the food that has been consumed and produce the energy (ATP) that powers every other cell.Thus, we can deduce that the statement "A mitochondrion produces energy from food to power cellular processes" accurately describes the function of organelle B.Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, movement, and homeostasis, ATP is used as the main energy source in turn.To learn more about mitochondrion refer to :

g Define nitrogen balance and describe how it is used to assess protein requirements in humans. Give examples of positive, zero (equilibrium), and negative nitrogen balance in humans.
Answer:
The nitrogen balance refers to the ingested nitrogen, one gram of nitrogen is equivalent to 6.25 g approx of protein.
Nitrogen in our body must be in balance, for that a large part is eliminated in urine, in the form of urea, and the rest through sweating, breathing and in epithelial expressions.
Explanation:
The nitrogen balance if it has a positive value is because we lose less than what we ingest in the day, if its value is zero, it is because the same thing that we ingest is we lose it in the day.
Instead, the problem is usually when the value is negative, here we are talking about the organism releasing more than we ingest, therefore some systemic failure will be happening.

The large object in the picture above is a single bacteria cell. The many small structures attached to it are viruses called
bacteriophages which are attaching to the receptor sites on the bacteria cell. Which of the following is one important
difference between a virus and a bacteria cell?
Answer Options:
a. a virus is much larger in size than a bacterial cell
b. a virus always causes more severe disease than a bacterial cell
c. a virus can never reproduce on its own, but a bacterial cell can
d. a virus does not contain genetic material, but a bacterial cell does
Answer:
c. a virus can never reproduce on its own, but a bacterial cell can
Explanation:
A virus is not cellular, and is significantly smaller than bacterial cells. Because they aren't cellular, to reproduce, viruses have to infect other cells. Inside the cell, they hijack the cell's machinery to allow their genome to be replicated and new viral particles to form. This is how viruses reproduce. Bacteria reproduce by asexual reproduction.

Answer: you suppose to use your own living state but..
sample answer
(Answers may vary.)
I live in Kansas City, Kansas. Kansas has the following characteristics:
Annual high temperature: 17.9°C
Annual low temperature: 5.8°C
Average temperature: 11.8°C
Average annual precipitation (rainfall): 867.2 mm
Kansas City has all four regular seasons. In spring, there is frequent fluctuation in the weather. The summer season has hot days and mild, warm nights. During the fall, the city has mild weather with sunny days and cool nights. Winters arrive by late October, with the first freeze. However, winters here are not severely cold. We rarely have snowfalls of 10 inches or more at any one time.

58. What do you think would happen if a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles
Answer:
Molecules or proteins will not be transported within the cells from organelles to organelles
Explanation:
If a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles, proteins will not be transported within the cell from one organelles to another because clathrin is a protein that lead to the formation of coated vessicles and these coated vessicles play a major role in vessicular transport by allowing the transport of proteins or molecules with the cells from organelles to organelles like organelles in the post-Golgi network connecting the trans-Golgi network endosomes and also cell membrane and lysosomes.

match each part of a virus with the best description of it.
Answer:
Envelope protein - proteins that stick out from the virus body
Envelope - protein shell around the virus
DNA/RNA - instructions to make more viruses
Capsid - container holding the DNA/RNA
Capsomeres - building blocks of the capsomeres
Explanation:
The envelope is the outermost layer of the virus. Envelope proteins are attached to the envelope and stick out. These are the proteins that bind to cell receptors to allow viruses to enter cells.
The capsid is made up of capsomeres, and it surrounds the genome of the virus. The genome is either made up of DNA or RNA, and contains instructions to make more viral particles.
