1. Name two biological processes that require cell division
2. Describe the relationship between the following terms: Chromosome, DNA and gene.
3. Why do you think it’s important that the DNA is copied before a cell divides?
Answer:
1.) Mitosis and Meiosis
In mitosis, a somatic cell divides in order to create two identical daughter cells. In meiosis, a germline cell divides twice to create four gametes.2.) A chromosome consists of two sister chromatids, each made up of tightly wound DNA. On these DNA strands are genes, which are specific sequences of nucleotides.
3.) It is important that the DNA is fully copied before the cell divides because cells always need DNA. If the DNA is not copied, one of the new daughters cells would not contain any DNA. Without DNA, the cell will no longer have the instructions necessary to perform its normal functioning.

Farmers can trigger uniform ripening times in fruit by treating plants with ________. Ethylene ethylene oligosaccharins oligosaccharins jasmonates
Answer:
ethylene is the blank word
Explanation:
Farmers can trigger uniform ripening times in fruit by treating plants with 2. ethylene.
Ethylene is a plant hormone that plays a crucial role in the ripening process of fruits. It is a gaseous hormone that acts as a signaling molecule, influencing various physiological processes in plants, including fruit ripening.
When plants produce ethylene naturally, it acts as a signal to initiate and coordinate the ripening of fruits. Ethylene triggers a cascade of biochemical and physiological changes that lead to fruit softening, color development, flavor enhancement, and aroma production.
Farmers can exploit the role of ethylene in fruit ripening by treating plants with exogenous ethylene. By applying ethylene to fruit crops, farmers can induce uniform ripening times, ensuring that the fruits in a crop reach the desired stage of ripe-ness simultaneously.
This technique is particularly useful for commercial fruit production, where uniform ripening is desirable for efficient harvesting, storage, transportation, and marketing purposes. It allows farmers to coordinate the timing of fruit ripening, leading to more consistent quality and appearance across the crop.
It's worth noting that other methods can also be used to manipulate fruit ripening, such as the use of synthetic plant growth regulators or other hormones. However, ethylene is one of the primary hormones involved in the natural ripening process, and its exogenous application is a commonly used method to trigger uniform ripening times in fruit crops.

Answer:
Bear shedding fur
Explanation:
Like dogs, bears lose some of their soft, dense insulating underfur as well as some of their coarse outer guard hairs when temperatures climb. That’s why bears can look very scruffy by late summer. As the weather cools and they layer on fat for hibernation, their underfur and guard hairs grow back.
2. How do the parts of the circulatory system work together
Answer:
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.

Greenhouse effect is caused by:
trapped carbon dioxide
trapped infrared energy
trapped greenhouse gasses
too many greenhouses.
Answer:
The answer is C. trapped greenhouse gasses
Explanation:
The greenhouse effect is the warming of the Earth's surface and troposphere (the lowest layer of the atmosphere) produced by the presence of water vapour, carbon dioxide, methane, and other gases in the atmosphere. Water vapour has the greatest impact of the gases classified as greenhouse gases.

just two of them, please and thank you
Type 2 Diabetes and different types of Cancer (colon, breast, endometrium, kidney, esophagus, and more are all linked to obesity.)
type 2 diabetes - when your body becomes resistant to insulin, cells are not able to absorb glucose and convert it into energy as a result of this resistance. it causes high blood sugar.
people who are obese have higher risk of several types of cancer, including colon, breast (in woman who have gone through menopause), endometrium, kidney, rectum, pancreas, gallbladder, etc

Which of these statements are true of DNA replication during the cell cycle?
Answer:
Explanation:
The statements that are true with respect to DNA replication are:
A. DNA replication is semiconservative.
D. The cell leaves S phase with two copies of each of its chromosomes.
DNA replication can be defined as a semiconservative biological process, through which two (2) identical replicas of deoxyribonucleic acid (DNA) molecules are produced from an original deoxyribonucleic acid (DNA) molecule, especially during cellular division.
Hence, DNA replication is a semiconservative biological process which involves the duplication of a double-stranded DNA to produce two (2) identical deoxyribonucleic acid (DNA) molecules i.e one (1) original and one (1) new strand.
We can deduce the following points from the above:
DNA replication is a semiconservative biological process.
During the S phase, the cell leaves with two (2) identical replicas of deoxyribonucleic acid (DNA) molecules i.e two (2) copies of each of its chromosomes.
