Cellular division (Mitosis) is the biological process whereby a parent cell breaks itself into different parts called daughter cells.

This process is important because it helps to divide cells so that they can:

Experience growth Repair broken cells Reproduce, etc

Cellular differentiation is the process of a cell going from one form to a more specialized cell.

A good example of this is the process of a fetus being formed from a single celled zygote.

What occurs if kelp is not present to absorb CO2 or produce O2?

Answers

there won't be fresh oxygen and CO2 will be dangerous for out health and we may not have some of the energy that we have today because kelp also can produce energy.

All other living organisms in the aquatic environment will be negatively affected if Kelp is not present to absorb CO2 or produce O2.

ROLE OF PHOTOSYNTHESIS:

Kelp are living organisms in the kingdom Protista, which possess the ability to photosynthesize or use energy from sunlight to produce food.

Photosynthesis is a process that absorbs CO2 from the atmosphere and release O2 as a gaseous product.

Kelp is a producer of aquatic environment, which means it helps to absorb CO2 and release O2 into the atmosphere. This O2 is used for cellular respiration by other living organisms.

If kelp is not present to absorb CO2 or produce O2, other other living organisms in the aquatic environment will be negatively affected.

five (5) kidney diseases their symptoms and their effect​

Answers

Answer:

Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:

toxic exposure to environmental pollutants or certain medications

certain acute and chronic diseases

severe dehydration

kidney trauma

Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.

Usually, someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:

a reduced amount of urine

swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste

unexplained shortness of breath

excessive drowsiness or fatigue

persistent nausea

confusion

pain or pressure in your chest

seizures

coma

Symptoms of early-stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:

decreased urine output

fluid retention that leads to swelling in limbs

shortness of breath

A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:

a heart attack

heart disease

scarring of the liver or liver failure

dehydration

a severe burn

an allergic reaction

a severe infection, such as sepsis

High blood pressure and anti-inflammatory medications can also limit blood flow.

When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:

prostate (a most common type in men)

colon

cervical

bladder

Other conditions can interfere with urination and possibly lead to kidney failure, including:

kidney stones

an enlarged prostate

blood clots within your urinary tract

damage to your nerves that control your bladder

Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.

The following may cause ischemia:

severe bleeding

shock

renal blood vessel obstruction

glomerulonephritis

Which of the following will impact a populations equilibrium ?

. Random Mating
. No mutations
. Small population
. No Migration

Answers

Answer:

". Small population"

Explanation:

      The conditions to maintain the (Hardy-Weinberg) equilibrium are no mutation, no gene flow, a large population size, random mating, and no natural selection. This can be disrupted by changes from any of its five main factors. No migration, no mutations, and random mating are all a part of this equilibrium, so the answer will be a small population.

There is a strong relationship between organism complexity and genome size in eukaryotes. Select one: True False

Answers

The statement 'There is a strong relationship between organism complexity and genome size in eukaryotes' is FALSE. The genome of an organism is all genetic information of that individual.

The genome is represented by all nucleotide (DNA) sequences that form the genetic makeup of an organism.

The genome is composed of protein-coding genes and non-coding sequences, which often exhibit regulatory functions.

The proportion between protein-coding sequence and non-coding sequence is not linear, thereby the complexity (i.e., the amount of different types of proteins encoded by the genome) and genome size in eukaryotes is variable among species.

Compare the population growth rate in industrially developed countries to that in developing countries

Answers

Answer:

The worlds developing regions will see 1.2 billion people added, a 20.7% increase; while the population of developed countries will increase a mere 3.3% adding 41 million to the current 1.3 billion people. ... There is a difference of more than ten years between the median age in developing and developed regions.

The population growth rate in industrially developed countries is much lower than that in developing countries.

The population growth rate is the number of births per 1,000 people in a population in a year. The population growth rate in industrially developed countries is typically around 1%, while the population growth rate in developing countries is typically around 2%.

There are several reasons why the population growth rate is lower in industrially developed countries. First, people in industrially developed countries tend to have fewer children. This is due to a number of factors, including the availability of birth control, the increasing participation of women in the workforce, and the rising cost of raising children.

Second, people in industrially developed countries tend to live longer. This is due to advances in medicine and healthcare. As a result, the number of people in the population who are of childbearing age is lower in industrially developed countries than in developing countries.

The lower population growth rate in industrially developed countries has a number of implications. First, it means that the population in these countries is aging. This is because the number of people who are of working age is shrinking, while the number of people who are retired is growing.

Second, the lower population growth rate means that there is less pressure on resources such as land, water, and food. This can help to reduce poverty and improve the standard of living in these countries.

However, the lower population growth rate also means that there is a smaller pool of workers to support the economy. This can lead to labor shortages and economic problems.

Overall, the lower population growth rate in industrially developed countries has both positive and negative implications. It is important to carefully consider these implications when making policy decisions.

What is the % of water inside the cell
Will osmosis occur
If so , which will water move (into or out of the cell )?
Will the cell swell or shrink ?
The cell is In what type of solution ? (Hypertonic , hypotonic ,isotonic ) help pls

Answers

The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

What is osmosis?

Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.

Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.
