Answer:

The RARA gene on chromosome 17 provides instructions for making a transcription factor called the retinoic acid receptor alpha (RARα). A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity (transcription) of particular genes.

Explanation:

Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.

Answer:

Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick

Explanation:

mRNA Vaccines Are New, But Not Unknown

This means the process can be standardized and scaled up, making vaccine development faster than traditional methods of making vaccines. mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV).

The answer is A

Explanation:

All the the different limbs all have an upper arm bone which is the humerus and two forearm bones which are the ulna and the radius.

The limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.

A common ancestor may be defined as an ancestral organism that is significantly shared by two or more descendent lineages. In a more simple term, an ancestor that they have in common. These ancestors follow each taxon's lineage back in time until all the lineages meet up.

A Common Ancestor is a lineage that undergoes cladogenesis, that is, branching evolution, such that more than one species can trace its ancestry back to the common ancestor or, more accurately, to multiple common ancestors.

Therefore, the limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.

The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."

Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

The release of oxygen gas will be the slowest under the red colored bulb.

It should be noted that phycoerythrin is a red pigment that's present in cryophytes and red algae. It's vital for the main chlorophyll pigments that are necessary for photosynthesis.

It should be noted that phycoerythrin reflects red light. Therefore, the release of oxygen gas will be the slowest under the red colored bulb.

In conclusion, the correct option is D.

Explanation:

A.

The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.

B.

The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.

Answer:

2. octopuses

Explanation:

A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus.

Octopuses belongs in class Cepholopoda. So, the correct option is (B).

A cephalopod is defined as any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus where specifically marine animals with bilateral body symmetry, a prominent head, and arms modified from primitive molluscs or is characterized by a set of tangents foot. These animals use gills to breathe and are invertebrates (lack backbones).

Cephalopods are most notable for their many arms and soft bodies, while ancestral cephalopods are known mostly from their shells because they are well preserved as fossils. The octopus, squid, cuttlefish, and chambered nautilus are familiar representatives.

Thus, Octopuses belongs in class Cepholopoda. So, the correct option is (B).

The “recommended temperature limit” indicates limit of the temperature that is good for our world and above this limit causes adverse affect.

Explanation:

The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..
