Answer:
-They do not use live viruses
-The vaccine with mRNA never enter the nucleus
-The vaccine ilicits an immune response
-The cell breaks down the mRNA after it delivers its instructions.
Explanation:
mRNA vaccines are a new class of vaccine which can be used to fight against infectious pathogens such as, for example, viruses. These vaccines are based on the design of a messenger RNA (mRNA) sequence that is introduced into de body to encode a protein of the pathogen (or even just a fragment of a protein) and consequently elicits an immune response after infection. Since pathogens need to produce many different proteins to be harmful to the host organism, a single mRNA molecule of the pathogen can trigger an immune response but does not cause the disease. mRNA vaccines don't enter into the nucleus of the cells and therefore they never interact with DNA. mRNA vaccines don't need viral vectors (e.g., adenoviruses) to be introduced inside the body. Moreover, traditional vaccines are those that use inactivated versions of the pathogen in order to trigger immune responses.
Why is ocean acidification dangerous?2-3 complete sentences
Answer:
Carbonate is important to marine life, especially those with exoskeletons and shells, who form their protective casings from carbonate. Ocean acidification reduces the amount of available carbonate, and can cause their shells to crumble and dissolve. Animals then have to spend extra energy either repairing their shells or thickening them to survive.

Answer:
I guess it consumes food.
Explanation:

Answer:
Each parent contributes, on average, half of the genetic material of each child. If a parent has n children, what percentage of the parent’s genes exist in total across all n offspring?

Answer:
Both are harmful for the organism in case of point mutation. In case of deletion or insertion of a particular fragment of the gene, deletion could be more harmful than insertion, because the deleted fragment of the gene will never be replaced at exact size and exact position of the disabled gene.

1. A cool piece of iron gets warm when a red-hot piece of iron is placed a few inches
away. How is heat transferred in this scenario?
Answer:
Convection currents in the air between the pieces of metal transfer all the heat. The air between the two pieces of iron emits thermal radiation that is absorbed by the cool iron.
There you go, hope this helped.
Heat energy is transferred from one matter to another through various modes and methods. A cool iron piece heats due to convection that transferred the heat from the hot iron.
What is convection?Convection has been one of the modes of thermal heat transformation that uses matter to transfer the heat from higher to lower concentrations, unlike the radiation mode. The matter particles move from hot to lower temperatures.
The air present between the cold and hot iron piece acts as the medium by which the cold iron piece absorbs the heat transferred by the hot iron piece. This thermal energy is emitted and absorbed due to the difference in temperature.
Therefore, the process of convection facilitates the thermal heat transformation from hot to cold iron objects.

A grasshopper is an arthropod. Based on the grasshopper’s characteristics, which other animal likely belongs to this group?(1 point)
The grasshoppers are a group of insects that belong to the Califera suborder. The grasshoppers are arthropods. Another animal that shares similar characteristics to a grasshopper and belongs to this group is the crayfish.
What are the characteristics of grasshoppers?Grasshoppers are plant eaters and over time they may become pests for various cereal crops and vegetables. They are herbivores insects with hind legs that are very powerful.
Like other insects, grasshoppers breathe through tiny holes called spiracles that connect to trachea tubes. The air is carried through the grasshoppers' bodies by smaller tracheoles that branch off from the larger trachea tubes. The grasshopper breathes air through its body with every movement. Grasshoppers don't have lungs.

Considering the most important ecological issue of the future, what is the biggest challenge the world will face in its dedication to conservation and restoration in the future?
The number of species in an extinction vortex
Spread of disease and parasites via corridors
The amount of land and energy resources
The pressures of its growing population
Answer:
its the amount of land and energy resources or the pressure of its growing population.
Explanation:
It is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.
What is population growth?As the population grows, there will be an increased demand for food, water, energy, and land, which will lead to habitat loss, deforestation, pollution, and climate change. These factors can exacerbate other ecological issues, such as the number of species in an extinction vortex and the spread of disease and parasites via corridors. Therefore, it is crucial to address the root cause of these problems by promoting sustainable practices and reducing our impact on the environment.
Hence, it is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.

1. State three ways in which protein are important to plant
(3marks)
Proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).
Proteins are fundamental biomolecules composed of amino acids linked by peptide bonds.In cells, proteins can play diverse structural and enzymatic roles.For example, structural proteins are required to synthesize ribosomes, which serve to assemble other proteins that form the cytoskeleton of cells. Moreover, enzymes are proteins capable of catalyzing chemical reactions such as photosynthetic reactions.In conclusion, proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences have a genetic basis, predict what will likely happen to the songs of the two frog populations.
A. You cannot predict a change in the courtship songs at the two lakes.
B. Disruptive selection will cause the songs to differentiate even more.
C. The songs will become more similar to each other.
D. Males will become louder.
E. Genetic drift will cause the songs to differentiate even more.
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
