Nondisjunction occurs when chromosomes do not properly separate during cell division, which can lead to?.(please no links just written answers)
Group of answer choices
Duplications
Translocations
Aneuploidy
All the above
Answer:
Option C, Aneuploidy
Explanation:
Aneuploidy is defined as the condition when offspring/daughter cell has abnormal number of chromosomes.
In the process of nondisjunction, the pair of homologous chromosomes do not separate and hence the sister chromatids fails to separate.
Hence, option C is correct
why is cycling carbon important
Answer:
The carbon cycle describes the way the element carbon moves between the Earth's biosphere, hydrosphere, atmosphere, and geosphere. It is important for a few reasons: Carbon is an essential element for all life, so understanding how it moves helps us to understand biological processes and factors that influence them.
Explanation:
Answer: Emissions of Carbon and other greenhouse gasses are a majoy factor in Gloabal Warming.
Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

explain why the concentration of FSH in the blood increases after day 1
Answer:
As the levels of FSH and LH in the blood increase with puberty, the eggs begin to mature and a collection of fluid — the follicle — begins to develop around each one. The first day of menses is identified as cycle day one. Estrogen is at a low point. ... This increase in estrogen begins to inhibit the secretion of FSH.

State the function of centromere
Answer:
The primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis.

What would you tell a classmate who claims that food is destroyed when you eat it?
Answer:
I would say "yes true", when you swolowing your food, your stomach is breaking down all of the pieces that you ate and taking apart all the nutrients that are in your burger or your hot dog or whatever you just ate.
Explanation:
Hope this helps
"Yes true," since your stomach is dissolving all of the food bits you ate and dissolving all of the nutrients in your hamburger, hot dog, or whatever you just ate.
How does food break down in the stomach?Peristalsis forces the food into your stomach after you have swallowed it. Stomach. Your stomach's lining contains glands that produce stomach acid and digestive enzymes.
These digestive liquids are mixed with the meal by the muscles in your stomach.
The meal is broken down into much smaller, digestible bits by the stomach muscles as they churn and combine it with digestive secretions that include acids and enzymes.
Therefore, the digestion that takes place in the stomach requires an acidic environment.

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase
their possibility of survival. This is an example of:
a. Artificial Selection
b. Adaptation
c. Biodiversity
d. Homeostasis
Answer:
B adaption
Explanation:
The scenario in which the Pandas evolve longer wrists to better eat bamboo over a long period will increase the possibility of artificial selection. The correct option is A.
What is artificial selection?Artificial selection, also renowned as "selective breeding," is the practice of selecting for positive traits in agricultural products or animals rather than allowing the species to change and evolve naturally, as in natural selection.
The process by which organisms can choose individual lifeforms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve.
Adaptation entails dealing with both the physiological abiotic environment such as light, dark, temperature, etc. but in addition to the intricate biotic environment.
Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase their possibility of survival. This is an example of artificial selection.
Thus, the correct option is A.

If a physician orders that a patient be given 4 grams of a medication that it is only available in 1000
milligram tablets, how many tablets should the natient hominen?
Answer:
4 tablets
Explanation:
Based on the information in this question, a doctor/physician orders that a patient be given 4 grams of a medication. However, the medication is only available in 1000 milligram (mg) tablets.
Since 1000mg = 1g
This means that one of the available tablet is 1g.
Hence, in order to give exactly 4grams of a 1g tablet, 4/1 = 4 tablets must be given to the patient.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube
Answer:
Diffusion and active transport.
Explanation:
Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

The moray eel and grouper fish hunt together. When both hunt together, prey barely stands a chance: hide in the reef, the eel eats you; dash for open water, the grouper grabs you. Which symbiotic relationship is described above?
A. Coevolution
b. Mutualism
c. Parasitism
d. Commensalism
Answer:
We can immediately cross-out C
We can also cross-out A.
Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
I would say D: Commensalism. Both fish can survive without each other.
