When does DNA replication happen and why?
Answer:
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions
What are some helpful and harmful examples of dna mutations
Answer:
Examples of helpful mutations embrace HIV resistance, milk sugar tolerance, and colored vision.Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes.Marine dead zones can form when nutrient run-off causes certain types of algae to grow very quickly and then die off. As dead algae decompose, oxygen is removed from the water. With less oxygen available, fish and other marine animals can die. What would be one practical way to reduce marine dead zones?
A: Add bacteria that are able to eat the fast-growing algae.
B: Harvest marine fish in dead zone areas to reduce oxygen use.
C: Pump oxygen into the water using equipment on fishing vessels.
D: Prevent fertilizer and other wastes from entering rivers and streams.
Answer:
The answer is D.
Explanation:
The practical way for reducing the marine dead zones should be that it prevented the fertilizer.
What is fertilizer?It is the type of natural material or the synthetic origin that should be applied for soiling or to plant tissue for supplying the nutrient of the plants.
It should be distinct from material liming for non-nutrient soil amendments.
Therefore, we can conclude that the option d is correct.

Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar levels normal, but hormones produced during pregnancy deactivate the cells. After pregnancy, hormone levels return to normal, and so do the pancreas cells. Is this an example of DNA or the environment controlling gene expression? Explain your answer
Answer:
environment controlling gene expression
Explanation:
Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.
The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.
Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.
This it is a result of the environment control gene expression.
Is It possible for two parents with a round jaw to have a child with a square jaw? Why or Why not
Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.
Meiosis I involves separation of homologous chromosomes but meiosis II involves separation of chromtids.
Answer:
Meiosis I: in meiosis I there is pair of chromosomes called homologous chromosomes which are to be seperated so one of that two chromosomes right pole of the cell and the second one goes to the left pole so each pole gets a chromosome with two sister chromatids.
Meiosis II: While in meiosis II homologous pair is not formed and single array of chromosomes are arranged to form metaphase plate as formed in Mitosis so, when the spindle fibres contracts each sister chromatids went to their respective poles.

Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.

ASAP The levels of water and salt in the blood are controlled by the ________, which is controlled by the ________.
Answer:
the hormone that regulates the salt and water levels is aldosterone found on the adrenal gland that sits above the kidney
Explanation:
Aldosterone, a hormone found in the adrenal gland above the kidney, regulates salt and water levels which are usually regulated by the renin-angiotensin system.
What is aldosterone?Adrenal glands secrete aldosterone, a steroid hormone. Its primary function is to regulate salt and water in the body, thereby influencing blood pressure.
It is actually regulated by a system namely the renin-angiotensin system.
Thus, aldosterone, a hormone found in the adrenal gland above the kidney, regulates salt and water levels which are usually regulated by the renin-angiotensin system.

All animals must be able to take in information and react to their environmental conditions. Describe the organs and organ systems in humans that work together to collect information about the external environment.
Answer:
Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses. When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.
All animals must be able to take in information and react to their environmental conditions through the Nervous system.
What are the 4 main functions of the nervous system?
Control of the body's internal environment to maintain 'homeostasis'.Programming of spinal cord reflexes. Memory and learning.Voluntary control of movement.Thus, the nervous system is the answer.

Question 1(Multiple Choice Worth 4 points) (01.03 LC) Organic molecules are sometimes found within meteorites that crash into Earth. Which meteorite condition in space is similar to what most likely was present in Earth's early atmosphere? Abundance of oxygen Very cold temperatures Presence of inorganic molecules Low levels of ultraviolet radiation
Answer:
Presence of inorganic molecules
Explanation:
Earth's primitive atmosphere contained a mix of different inorganic compounds (gases) including, among others, water vapor (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), etc. It has been proposed that these inorganic molecules would generate the conditions needed to form a "primordial soup" of organic molecules (i.e., RNA nucleotides, amino acids, etc). Subsequently, this soup would accumulate in water bodies of the primitive Earth due to endogenous abiotic syntheses and the delivery caused by comet/meteorite collisions.
Answer:
C. Presence of inorganic molecules
