What is not a trigger for juxtaglomerular granular cells to release renin?
The provided question is incomplete as it lack the group of choice required to answer, however, the correct options are as follows:
A) increased extracellular fluid water levels
B) decreased filtrate NaCl concentration
C) sympathetic stimulation
D) decreased stretch due to decreased blood pressure
Answer:
The correct answer is option A) increased extracellular fluid water levels
Explanation:
Juxtaglomerular granular cells are the group of cells present in the kidney that produce, store and release the enzyme known as the renin. These cells are present in the walls of the afferent arterioles mainly.
Renin is the enzyme release in order to release angiotensin I in order to increase the blood pressure. The release of the renin is depend on various triggers sense by juxtaglomerular granular cells such as decreased filtrate NaCl concentration , decreased stretch due to decreased blood pressure and sympathetic stimulation or other stimuli. However, increased extracellular fluid water levels is not responsible for the release of renin.
Thus, the correct answer is option A) increased extracellular fluid water levels

The majority of thyroid hormones are secreted as ______but small amounts of _____is also secreted from the follicle.
Answer:
The correct answer is - T4, and T3.
Explanation:
The Thyroid glands are butterfly shape glands madeup of microscopic spherical structures known as thyroid follicles made up of cuboidal follicular cells. These cells produces the both major hormones of thyroid gland T4, and T3.
The majority of thyroid hormones are produced as T4 hormones approximately 80% but a small amount of 20% is released in the form of T3 hormones. However, the most active form of the thyroid hormone is T3 and to act on target cells, one iodine molecule have to be removed to convert T4 to T3.

A molecule that binds up excess hydrogen ions in a solution is called a(n) ________.
1. acid
2. isotope
3. base
4. donator
a base
isotopes have nothing do with binding hydrogen ion
acids donate hydrogen

A BASE is a molecule that binds up excess hydrogen ions in a solution.
WHAT IS A BASE?
According to the Bronsted-Lowry theory of acids and bases, a base is a substance that accepts hydrogen ions (H+) which was donated by an acid.For example, in the chemical reaction below:
HCl (aq) + NH3 (aq) → NH4+ (aq) + Cl- (aq)
NH3 (ammonia) is the base because it accepts the hydrogen ion (H+) donated by hydrochloric acid (HCl) to form ammonium (NH4+).Hence, in a solution, a base binds up any excess or released hydrogen ion.

What is 0.55 hectometers expressed in decimeters?
550 dm
b. 5.5 dm
c. 55 dm
d. 0.00055 dm
Answer:
A 550
Explanation:
0.55 hectometers is equivalent to 550 decimeters.
Since 0.01 hectometers and 10 decimeters (1 meters) are both equal to one meter, :550 decimeters (55 meters) are equal to 0.55 hectometers. Thus, option A is correct.
What are hectometers and decimeters?
The International System of Units (SI) defines the hectometer (International spelling as used by the International Bureau of Weights and Measures; SI symbol: hm) or hectometer (American spelling) as a unit of length that is equal to 100 meters and one tenth of a kilometer.
The ruler, which is 12 inches (0.3 m) (in) or 30 centimeters (cm) long and equals one foot or slightly under one-third of a meter, is visible. 100 meters make up a hectometer.
To produce one hectometer or 328 feet (99.97 meters), that would need about 328 rulers. That is a lot of rulers, I must say. Here is a simpler method for recalling a hectometer's length.
Decimeter measurements are uncommon in everyday life. It is simpler to use 0.1 m or 0.5 m when the length is less than a meter because one meter is not a particularly length.
Therefore, 550 decimeters (55 meters) are equal to 0.55 hectometers.

In a nutrient medium that lacks histidine, a thin layer of agar containing around 10^9 Salmonella typhimurium histidine auxotroph produces around 13 colonies over a two day incubation period at 37 degrees centigrade. How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of 0.4 micrograms of 2-aminoanthracene. The number of colonies the number of colonies produced over 2 days exceeds 10,000. What does this indicate about 2- anthracene? What can you surmise about its carcinogenicity?
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at loci responsible for the synthesis of histidine.

O AtRNA template is used to create an mRNA strand.
O An mRNA template is used to create an amino acid chain.
Answer:
[tex]\huge\boxed{Option \ 4}[/tex]
Explanation:
In translation process, the messenger RNA (mRNA) template is used to create amino acid chain by which a protein is formed. Translation is the process of synthesis of proteins from amino acids which the help of mRNA.
The option that best describes something that occurs during translation is an mRNA template being used to create an amino acid chain.
Translation, also known as protein synthesis, is one of the steps in gene expression. It involves the translation of genetic codes in an mRNA molecule to their respective amino acids in the ribosome.
The first step in gene expression is the transcription of genetic information on DNA into codes in the form of an mRNA. The mRNA then undergoes some processing before the genetic codes are translated, with the help of the tRNA which carries the anticodons, in the ribosome.
The codes are not just translated to their respective amino acids but the latter are joined together by peptide bonds to form the primary structure of proteins.

precipitation, which can lead to
Answer:
Increased evaporation and transpiration dries out the ground leaving less water to move to the atmosphere fewer clouds and less precipitation, which can lead to drought conditions.
In some areas evaporation and transpiration from plants can be so high that the amount of water available to move to the atmosphere is significantly reduced. This is usually the case in areas that are lacking in open water resources.
As there is less water moving to the atmosphere, there will be less water condensing into clouds and thus less rain. If this persists, it can lead to a drought.
Proteins can buffer a drop in pH by their _____ side groups and can buffer an increase in pH by their _____ side groups.
Answer:NH2 side group and COOH side group.
Explanation:
Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.
What are Proteins?Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.
Many thousands of amino acids, which are smaller building blocks of proteins, are linked together in lengthy chains to form proteins. To create a protein, 20 distinct kinds of amino acids can be mixed. Each protein's precise function and distinctive 3-dimensional structure are determined by the order of the amino acids.
Combinations of three DNA building units (nucleotides), which are dictated by the order of genes, are used to code for amino acids.
Therefore, Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.
