The answer would be A

Because

The sense of smell is part of our chemical sensing system, or the chemosenses. Sensory cells in our nose, mouth, and throat have a role in helping us interpret smells, as well as taste flavors. Microscopic molecules released by the substances around us (foods, flowers, etc.) stimulate these sensory cells. Once the cells detect the molecules they send messages to our brains, where we identify the smell. Olfactory, or smell nerve cells, are stimulated by the odors around us--the fragrance of a gardenia or the smell of bread baking. These nerve cells are found in a small patch of tissue high inside the nose, and they connect directly to the brain. Our sense of smell is also influenced by something called the common chemical sense. This sense involves nerve endings in our eyes, nose, mouth, and throat, especially those on moist surfaces. Beyond smell and taste, these nerve endings help us sense the feelings stimulated by different substances, such as the eye-watering potency of an onion or the refreshing cool of peppermint.

What type of solution is this cell sitting in?

Dafna1 [17]

Answer:

The correct option is A. The cell is sitting in a hypertonic solution.

Explanation:

A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.

As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.

Climate change in the form of global warming (an abiotic factor) has slowly decreased habitat for the arctic seals. What are the

almond37 [142]

The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

<h3>What is population dynamics?</h3>

Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.

Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.

With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

How does mitochondrion contribute to the protein synthesis

snow_tiger [21]

Mitochondria use proteins to break down sugars and produce cellular energy in the form of ATP. ... No matter where mitochondrial proteins are made, they are synthesized on ribosomes that translate messenger RNA into the amino acids that form the protein chain.

the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes i

Helga [31]

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.

Many molecules are moved through the body by

Solnce55 [7]

Question: Many molecules are moved through the body by?

Answer: The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules. Carrier proteins blind and carry the molecules across the cell membrane. They provide an open channel of passageway through the cell membrane for molecules to move across.

Hope this helps!.
