Answer it right plz

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).

Answer:

chemical evolution

Explanation:

This type of evolution is what we believe started the origin of life. Chemical evolution is when something changes to have different abilities (which in this case would be true).

Have a great day everybody!

Answer:

cytoplasm

Explanation:

The cytoplasm's job is to hold organelles in place and it is a jelly-like substance.

Answer:

Hydrogen disulfide

Explanation:

Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.

It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.

Answer:

Hydrogen monoxide

Explanation:

It is very toxic to smell in farts

Answer:

Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface

Explanation:

Q1: The term "salinity" refers to the concentrations of salts in water or soils.  Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold.  Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense.  As more solids are dissolved in water, the water becomes more dense.  Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.  I really need brainliest please do so.

I'm not 100% sure what you're asking but is this what you mean?

All plants are tall.

        r           r

R      Rr         Rr

R      Rr         Rr

Answer: In pea plants, a tall stem is dominant (R) over a short stem (r).

This means the genotype of the tested plant is RR so that one would be on top of the Punnett's square.

The Punnet's square would be as follows:

Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.

Explanation:

The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.

Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.

Symptoms of sickle cell anemia include infections, pain and fatigue.

Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

Explanation:

Answer:

Purple, waxy (R_W_) = 6

Purple, dull (R_ww) = 6

Yellow, waxy (rrW_) = 2

Yellow, dull (rrww) = 2

Phenotypic ratio = 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull)

Explanation:

This question involves two genes coding for kernel color and kernel appearance or ‘shine in corn plants. The alleles for purple kernel (R) and kernel waxy (W) are dominant over the alleles of yellow color (r) and kernel dull (w).

According to this question, a geneticist cross two corn plants that have the genotype: RrWw and Rrww. The following gametes will be produced by each parent:

RrWw - RW, Rw, rW, and rw

Rrww - Rw, Rw, rw, and rw

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Purple, waxy (R_W_) = 6

Purple, dull (R_ww) = 6

Yellow, waxy (rrW_) = 2

Yellow, dull (rrww) = 2

The phenotypic ratio expected from crossing these two parents is 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull).

Answer:

A. Individual organisms are able to change their genetic adaptations in

order to better survive in changing environments.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

The statements which are consistent with the concept of natural selection includes;

I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.

II. There is genetic variation within populations. This simply means that tere is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.
