Answer:
Image result for How do cells get energy from glucose?
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Paramecia that live in freshwater have contractile vacuoles, while those that live in salt water do not. Why do you think this is the case?
Answer:
water enters by osmosis, vacuole is used to pump out excess water.
Explanation:
Paramecia that live in freshwater would have contractile vacuole because they will need to get rid of excess water unlike those that live in salt water.
The vacuole primarily functions to get rid of excess water from the cell.
Freshwater is hypotonic to the cytosol of paramecia. Thus, water will always enter the paramecia cells by osmosis. If the excess water is not excreted from the cell, turgidity will result and the cell may burst.
On the other hand, salt water is likely hypertonic to paramecia cells. Thus, instead of having vacuoles for water excretion, a mechanism would have to be put in place so as not to lose too much water to the surrounding salt solution. In other words, a vacuole would be totally redundant in the hypertonic solution.

Which best explains why sexual reproduction produces greater variations among offspring? *
A The DNA come from two genetically different parents.
B The DNA cells from one parent that is genetically identical.
C The sex cells are produced by mitosis.
D The sex cells undergo self fertilization
Answer:
A The DNA come from two genetically different parents.
Explanation:
Everyone has different genetics. They are determined by sex cells that are produced by MEIOSIS NOT mitosis. Meiosis allows for genetic variation amoung offspring along with the genetically different parents.
The DNA come from two genetically different parents explains the best reproduction greater variations among offspring.
What is sexual reproduction?Reproduction is the act of one or more parents creating a new individual (offspring), frequently within the same species. It is among the characteristics of a living creature.
Sexual reproduction, we mean a process where two parents' genetic material is combined to create a child. When two haploid gametes combine, a genetically unique diploid child is produced.
The word "sexual" has a Late Latin etymology that stems from the word sexus, which means "of copulation or generation." The word reproduction is also derived from the Latin words re, which means "again," and productio, which means "creation." Alternative: syngenesis.
Therefore, The DNA come from two genetically different parents explains the best reproduction greater variations among offspring.

Barnacles and mussels are filter feeders that attach themselves to rocks in the ocean. They eat by filtering small particles of food from the ocean water as it flows over them. A scientist observed a dense colony of barnacles covering the surface of a rock. The mussels were only able to attach to a few, small crevices on the same rock.
Evaluate this observation and explain a limiting factor that is affecting the barnacles and mussels on the ocean rock
Answer:
The barnacles are only able to attach themselves to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
Explanation:
Oysters and cockles are related to mussels and barnacles. These species can be found in both salt and fresh water. They are marine creatures.
What is limiting factor?A limiting factor is anything that restricts the size of a population and slows or stops its growth. Limiting factors include biotic factors such as food, mates, and resource competition with other organisms.
These creatures have evolved to live on rocky shorelines. The mussels are filter feeders that take in seawater and filter out particles.
The barnacles are gonochoristic, whereas the mussels are hermaphroditic.
The mussels' zonation is the area around the intertidal zones of rocks, as they require food to grow.
Mussels and barnacles are related to oysters and cockles. These species are found in both fresh and salt water. They are marine creatures.
Thus, this is the limiting factor in the give scenario.

Knowing how food choices impact the function and productivity of cells, why do you think it is important to maintain a healthy diet? What can happen if someone continually eats junk food?
Answer:
healthy diet prevents and protects from diseases like obesity, heart disease, diabetes, cancer and stroke. constantly eating junk food can lead to obesity and chronic diseases like cardiovascular disease, type 2 diabetes, non-alcoholic fatty liver disease and some cancers.
Explanation:
Maintaining a healthy diet is important because food provides the energy and nutrients that cells need to function properly.
What is health?"Health is a positive concept that focuses on both social and personal resources as well as physical abilities."
This means that health is a resource to assist an individual in carrying out their societal function, rather than an end in itself.
Junk food can have an impact on cell function and productivity in a variety of ways. A high-sugar diet, for example, can cause insulin resistance, which impairs cells' ability to absorb glucose and produce energy.
This can result in fatigue and reduced productivity. A high-fat diet can also have an effect on cellular function by increasing inflammation in the body, which can interfere with immune system function and increase the risk of chronic diseases.
Thus, maintaining a healthy diet is important for supporting cellular function and promoting overall health and well-being.
