The diploid cells of a polar bear contain 74 chromosomes.
How many chromosomes are there
Answers
Haploid cells only have one copy of each chromosome. So we can find the number of chromosomes in a haploid cell by dividing the number of chromosomes in the diploid cell by 2.
76/2 = 37
So the haploid cell contains 37 chromosomes.
The genetic material that is passed from a parent to a child is called a chromosome. With a diploidy of 74 chromosomes, the haploid cell of the polar bear will have 37.
What is the difference between haploid and diploid cells?The number or ploidy of chromosomes in the somatic or germinal cells determines whether a cell is diploid or haploid. A twofold set of chromosomes is referred to as diploidy and is symbolized by the number 2n.
Haploidy, which is denoted by the number n, refers to the single or partial set of chromosomes found in germinal or reproductive cells. They describe the gametes that participate in fertilization.
If a polar bear's diploid cells (2n) have 74 chromosomes, its haploid cells (n) will have the following chromosome makeup:
2n = 74
n = 37
Therefore, option C is correct.

A
Differences in density caused by temperature differences create buoyant forces.
B
Gravity pulls cold air downward more strongly than warm air.
C
High-energy particles bounce upward off the ground in large numbers, causing convection.
D
Gravity acts on particles but not on energy, so thermal radiation rises.

Answer:
A) Density
Explanation:
cold air is more compact than warm air since particles aren't as active, therefore it is more dense and heavier than warm air.

What function of the cell does cancer mainly affect?
A. Cell division
B. Photosynthesis
C. Cell transport
D. Cellular respiration
Answers
A) Cell Division
Explanation:
When someone has cancer their cells grow abnormally and spread very fast ( which is bad because these cells have cancer in them which spread around your body it’s why most people who are in late stages of cancer usually develop it in other places) . Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.
Cancer cells usually group or clump together to form tumors.
Answer:
A. Cell division
Explanation:
Cancer cells are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair.

List one abiotic and one biotic factor that humans use to limit pest population.
Answers
Answer: temperature, animal
Explanation:
Abiotic factor is a non-living environmental factor like soil, water, temperature, humidity, sunlight, and others. Biotic factor is a living factor including living beings like microbes, humans, insects, and others. A limiting factor is the one which can reduce the abundance and growth of living organisms. A limiting factor can be abiotic or biotic.
Temperature is one of the abiotic factors which can reduce the abundance of pests. Increase in temperature can kill pests, which cannot tolerate the rise in temperature. Animal that feed on pests can also reduce the abundance or population of the pests. Like lizards, frogs, and others.
why has CO2 and other greenhouse gases increased so much since 1850

How have the factors that trigger an asthma attack changed since the 1900s? As a researcher, how would you put together the clues given here to explain the emerging epidemic?
Answers
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.

Explanation:
In most natural populations rapid exponential growth is unsustainable. As populations
increase, environmental resistance causes the growth rate to slow down, until carrying
capacity is reached. Brainstorm several factors that could be considered as environmental
resistance.
Answers
Carrying capacity is defined a the ability of the natural ecosystem to take care of the environment which does not necessarily cause the resistance in population increase.
Explanation:
The earth indeed has a mechanism of delivering changes to the system and keeping it intact but as the case of the rapid growth of population arises the mother nature sees this as an exponent of unsustainable growth as the resource used to sustain large populations is no longer available or are exhausted.
A population increase so does the carrying capacity and workload of the natural environment which at the time gets slow due either due to the man's artificial technology or the natural process like hurricane or earthquake itself.
But seeing the nature as providing possibilities for the existence of the societies throughout ages and hence trying to maintain its originality may break those activities that it considers resistance as several biotic factors like predators, disease, competition, and lack of food.
