Four identical plants are grown under
different colored light bulbs. Under which
color will the release of oxygen gas be the
slowest?
A. Blue
B. Orange
C. Green
D. Red
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.

These limbs provide evidence of common ancestry because they -
Answer
A have the same basic structure
B pedom the same function
С
are the same size
Dare parts of mammals
Answer:
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.
What is a common ancestor?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.

How do vaccines generally work?
What is the difference between traditional vaccines and mRNA vaccines?
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).
1. Do you think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved? Why or why not? Think about your opinion and then back it up with at least one fact.
Answer:
No.
Explanation:
I don't think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved because all other scientists also contributed in the work and work harder for it so the credit must be given to all scientists. If the credit will not given to other scientists so it is an unfair act so my opinion is against the credit given to Watson and Crick.
Water can travel upwards in the small tubes within plants. This is:
A. Surface Tension
B. Adhesion
C. Cohesion
D. Capillary Action
Answer:
D i think maybe right not sure
Answer:
D. Capillary action
Explanation:
Capillary action is defined as "the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension." All of the other answers are technically right because they are all present when the water is traveling upward, but Capillary Action is the most correct answer provided because it is the description of what is hapeneing as a whole.

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.

Help me on this please
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.
How can climate change be reduced? How can climate change be fixed? Is there any evidence for us to see that climate change has been affecting us?
Answer:
We can easily reduce and fix climate change by Using less greenhouse gasses and by switching to all electric. Unfortunately global warming has started to affect us in ways such as extreme weather, wildfires and even Global warming has shown to cause infectious diseases to spread more rapidly.

Calico cats are almost always female because the gene for coat color is
carried on the X chromosome. The Y chromosome in cats has no color
gene. Explain how a calico cat might be a male. *
Answer:In rare cases, a male cat can inherit two X chromosomes in addition to his Y chromosome (Klinefelter Syndrome). ... If the two X chromosomes do not carry the same allele (i.e., the cat's genotype is XBXbY), then the male will express calico coloration, just as a female would.

Which of the following animals belongs in class Cepholopoda?
1. snails
2. octopuses
3. glass sponges
4. jellyfish
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).
What is Cephalopod?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).
