Some kidney diseases cause a change in the permeability of glomerular capillaries making them more permeable to plasma proteins. This changes the colloid osmotic pressure, thus drawing water out of the blood and into tissues. The result is
Answer:
The correct answer is edema.
Explanation:
When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.
However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.

Suresh and Gail are students in a lab working on mice with defects in the function of the HOX3A gene. In the special mouse line they are working on, no sequence changes are present in the genomic DNA of HOX3A, but the gene is not expressed properly and a mutant phenotype results. In one mouse line, an mRNA is produced in normal amounts, but no HOX3A protein can be detected.
Suresh thinks the absence of protein results from a change in RNA processing that prevents the inclusion of an exon in the final mRNA. Gail thinks the absence of protein results from some second gene that produces a protein that binds to the 3'UTR. Which of the two could be correct?
A) Only Suresh could be correct.
B) Only Gail could be correct.
C) Both Suresh and Gail could be correct.
Answer:
C) Both Suresh and Gail could be correct.
Explanation:
The pre-messenger RNA (pre-mRNA) transcript obtained after transcription of eukaryotic genes must undergo several processing events, including a process known as intron splicing, where introns (i.e., the non-coding sections of an RNA transcript) are removed and exons (coding regions) are joined to form a mature mRNA molecule. The three prime untranslated (3′-UTR) region of this mRNA can also bind to regulatory non-coding RNAs such as, for example, miRNAs which inhibit gene expression by inhibiting translation and/or by triggering its degradation. Moreover, the 3′-UTR region may also contain silencer sequences that bind to repressors in order to inhibit gene expression. On the other hand, translation refers to the process by which an ordered polypeptide chain (i.e., a protein) is synthesized by using the information contained in an mRNA molecule. In consequence, in the case under consideration, the mutation in the second gene could affect both RNA processing and the regulation of translation, thereby equally affecting HOX3A protein synthesis.

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
Answer:
constant region of the light chain.
Explanation:
The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.

Answer:
Both earthquake and volcanoes are concentrated in specific regions.
Explanation:
The distribution of earthquake on earth is concentrated in specific zones where the plate tectonic meets or fuse with each other. Volcanoes are also concentrated in specific regions on the earth. Most volcanoes are concentrated on the edges of continents, on island chains, or long mountain ranges beneath the sea. There is a great relationship between earthquake and volcanoes because volcanic eruptions is the cause of earthquake in a region.
Explain Newton’s First Law and give an example of it
Answer:
When a person jumps out of a moving vehicle, he falls forward due to inertia of motion. One example of Newton's first law in real life is, when you are walking with a glass filled with water, you will notice that the water spills at certain locations when you walk at faster pace. The water inside the glass will remain at rest until you move.
Explanation:
Answer:Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
An object at rest stays at rest.

what are the names of the three domains
A.bacteria,archaea,eukaryotic
B.bacteria,archaea,animalia
C.archaea,plantista,animalia
D. Life,animals,plants
Answer:
A. bacteria, archaea, and eukaryotic.
Explanation:
Bacteria, archaea, and eukaryotic are the three domains of life.
The three domains system was globally implied. The three domains were Archae, Bacteria and Eukarya. The correct answer is option A.
The three domains of Carl Woese's categorization system are archaea, bacteria, and eukaryotes. The six kingdoms are archaebacteria (ancient bacteria), eubacteria (actual bacteria), protozoa, fungi, plants, and animals.
This classification system divides life into several groups based on differences in the 16S ribosomal RNA (rRNA) structure, the lipid composition of the cell membrane, and antibiotic sensitivity. The main distinction from earlier classification schemes is the division of Kingdom Monera into Archaea and Bacteria.
Therefore, the names of three domains given by Carl Woese were Archae, Bacteria and Eukarya i.e. option A.

12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments
Answer:
D
Explanation:
Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
What is Acid Precipitation?Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.
Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.
Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
