The correct option is B.
Having short breath and sharp pains in the chest are indications of cardiac distress and it indicate that the heart is been exerted upon. The first thing the nurse should do is to ask the patient to sit down in order to reduce the exertion force on the heart. Resting will allow the patient to become stabilized, the nurse can then check the patient's need for oxygen application.

The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
It is because leaves are the main users of photosynthesis in a plant. The sunlight seeps into the leaves, and the leaves transform the sunlight's energy into sugar; their food.
I hope this helps! :)
The answer is dominant.
A monohybrid cross involves organisms that are heterozygous for only one character. In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (A) are present (homozygous individuals AA) or only one copy of the dominant allele is present (heterozygous individuals Aa). <u>Thus, t</u><span><u>he characteristic that results from a monohybrid cross is the dominant trait.</u></span>
Answer:
See explanation
Explanation:
Fossil records contain an extensive detail of the evolution of various species on earth which have been preserved in the remains of these organisms or imprints that organisms that existed long ago must have left in sedimentary rocks.
Fossil records basically tell us about the past. They tell us about the species that once existed on earth. They also tell us how long these species existed and how the were related to other species.
This information help us to work out how these organisms lived and the environment where they lived.
