Varicella-zoster is the virus that causes chickenpox. The average incubation period is 14 to 16 days after exposure. A person usually experiences a mild fever and fatigue for 1 to 2 days before rashes appear all over the body. A person having had chickenpox as a child may have the virus lay inactive in the nerve cells for many years only to reactivate much later as an adult in the form of shingles, which results in a very painful rash. This information suggests that the reproductive cycle of the varicella virus is -
a)lytic for shingles because the virus causes rashes to appear on the skin.
b) lysogenic for chickenpox because the virus attacks the mucous membranes.
c) lysogenic because the virus is a varicella-zoster virus.
d) lytic for chickenpox because the symptoms appear soon after infection.

Explanation:
Consider the impact of each substance on cellular respiration. Each substance has an influence at the cellular level, and has no effect on hunger. Assume that the substances have no other impact on the cell other than the one described. Substance’s Effect: Makes the lipid bilayer of the inner mitochondrial membrane highly permeable to (H+) protons. Does it cause weight gain or loss?
Answer:
The correct answer is "Weight loss".
Explanation:
If the influence of material is such that it adversely affects the attachment of NAD+ to electrodes, it can help people lose weight. This because it will indeed necessarily imply that perhaps the ATP throughout the cells would've been whittled down unless the compound NADH could not have been established. This also suggests that because the body doesn't obtain adequate ATP, this also contributes to the breakdown of fat into some kind of type of stored energy which always promotes weight loss throughout the turn.i searched up tim and moby fan art. my eyes did not like what i saw.

The area where an ocean meets land is called the ____ zone.
aphotic
photic
intertidal
benthic
Answer:
the area where ocean meets land is called the intertidal zone
The area where an ocean meets land is called the "intertidal" zone. Therefore, option (C) is correct.
What is intertidal zone?The intertidal zone, also known as the littoral zone, is the area of the shoreline that is exposed to air at low tide and submerged underwater at high tide. This zone is the boundary between the land and sea and is constantly affected by the ebb and flow of the tides. The intertidal zone is characterized by its unique physical and environmental conditions, such as the exposure to air and sunlight, the fluctuations in temperature and salinity, and the constant pounding of waves.
Due to these environmental conditions, the intertidal zone is home to a diverse range of plant and animal species that have adapted to the harsh and dynamic environment, such as barnacles, mussels, crabs, and seaweed. The intertidal zone is an important ecosystem that provides habitat, food, and breeding grounds for many marine species, and is also a popular area for recreation and scientific research.

There are several ways to produce the amino acids that build a protein. What does this mean?
Answer: Some MRNA codons code for multiple amino acids. So they can produce amino acids many ways, that build a protein.
There are several ways to produce the amino acids that build a protein because the genetic code is DEGENERATE or REDUNDANT.
In a given messenger RNA (mRNA) sequence, the triplets of nucleotides or 'codons' indicate specific amino acids to be added during protein synthesis.
The genetic code is said to be 'degenerate' or 'redundant' because different codons may encode the same amino acid.
For example, both the AUC codon and AUA codon in mRNA specify isoleucine, so alterations (i.e., mutations) in the nucleotide sequence do not always alter the protein sequence.
In conclusion, there are several ways to produce the amino acids that build a protein because the genetic code is DEGENERATE or REDUNDANT.

The following statement compares different starches: Because it is branched and can be broken down to ________ by multiple enzymes at the same time, _________ is digested more quickly than _________. The following statement compares different starches: Because it is branched and can be broken down to ________ by multiple enzymes at the same time, _________ is digested more quickly than _________. lactose; amylose; amylopectin fructose; cellulose; amylopectin monosaccharides; amylopectin; amylose simple sugars; cellulose; amylose amylopectin; amylose; glycogen
Answer:
monosaccharides
amylopectin
amylose
Explanation:
Monosaccharides is any of the class of sugars such that it cannot be hydrolysed into a simpler sugar.
Amylopectin is the non-crystallizable form of starch that consists of a branch of polysaccharide chains.
Amylose is the crystallizable form of starch that consists of an unbranched polysaccharide chains
The following statement compares different starches: Because it is branched and can be broken down to monosaccharides by multiple enzymes at the same time, amylopectin is digested more quickly than amylose.

Answer:
C) are sequence-specific DNA endonucleases
B) degrade foreign DNA that enters a bacterium.
Explanation:
Restriction enzymes are the proteins that cut the DNA at a specific sequence.
Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. So, Restriction enzymes are sequence-specific DNA endonucleases.
The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.

what are the importance of planting and propagating trees and fruit bearing trees?
Answer:
Planting and propagating trees and fruit bearing trees are important because without these we won't have fruits to eat, our land will suffer from soil erosion, there will be landslide and flooding and we won't have fresh air to breathe.
Planting and propagating trees and fruit-bearing trees is important in a variety of ways:
Many fruits from trees serve as food for other organisms, including man. Fruits are rich in important nutrients that are essential for the health and survival of man.Trees are sources of timber for various construction works for man. Trees serve as habitats for other living organisms like insects, birds, etc. These organisms serve important ecological functions in the ecosystem.Trees are important for tackling water erosion. The roots of trees hold the soil structures together while their leaves reduce the force with which raindrops hit the ground.Trees help with carbon fixation. Thus, they help rid the environment of pollution and purify the air.Branches of trees also act as breakages during wind, thus, protecting the environment.More on the functions of trees in the environment can be found here: https://brainly.com/question/23108922
Your airways are coated with a thin layer of liquid called ASL and a mucus gel layer, both which neutralize foreign particles to prevent infection. In people with
Cystic Fibrosis, a gene has an error, which causes the cells of the airways (lungs, etc) to have defective plasma membranes The ASL and mucus are much
thicker than usual near the defective cells, causing a lot of lung congestion because the defective cells allow too much salt into the cells Why would allowing too much salt into the cells create thicker ASL and mucus?
À. The increased salt in the cells makes the person thirsty, leading to thickened ASL and mucus in the lungs
B. The increased salt in the cells causes water from the airways to move into the cells by osmosis, thickening the ASL and mucus in the lungs.
