A) Crossing over occurs in : Meiosis I ( D )

B) DNA replication would occur : Prior to meiosis I and meiosis II ( B )

C) The embryo's development represents ; meiosis and cell differentiation ( D )

D) Some organisms reproduce aseggsually ; To rapidly produce like offspring

Crossing over involves the swapping of genetic materials, and it occurs in prophase I of meiosis before meiosis II the crossing over of genetic materials are over. while DNA replication is the process whereby DNA make an exact copy of itself during the process of cell division and this process occurs prior to meiosis I and meiosis II

The development of an embryo in the missing diagram represents meiosis and cell differentiation.

Hence we can conclude that the answers to your questions are as listed above.

Answer:

Back Pain and Stiffness; kind of relation to Hunchback?

Explanation:

It happens when we have poor posture; positioning our arms & shoulders not how we normally position them - it can also happen when carrying heavy stuff or slouching.

Answer:

The ligaments and muscles that support the vertebrae can extend as a result of poor posture in childhood, such as leaning back in seats and carrying heavy backpacks. Kyphosis occurs when the thoracic vertebrae are pulled out of their usual position.

Answer:

No they cannot fly

Explanation:

Penguins dont have any feather to fly with

Answer:

Well, in a sense they really do fly, only through the water, not through the air. Their wing bones are fused straight, making the wing rigid and powerful like a flipper. Penguins don't really need to fly because they dive deep, and swim so that they can catch their prey. Their bodies have huge fat supplies, heavy muscles, and densely packed feathers. There’s no way they could fly with such short wings and heavy bodies.

Answer:

The answer is The substrate will not be able to attach to the enzyme's active site.

Because the function of inhibitors is to block the enzyme's activity

Explanation:

PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT

The substrate will not be able to attach to the enzyme's active site. So the correct option is A.

The inhibition is carried out by inhibitors that do not advance the product's development. The inhibitors may affect the enzyme as well as the substrate. Enzyme inhibition is the term used to describe the cessation of enzyme activity.

These enzyme inhibitors can bind to active regions and prevent further action by stopping it. Both reversible and irreversible forms of binding are possible. The ability of an inhibitor to block an enzyme may be irreversible or reversible depending on its unique function. Enzyme inhibitors can block the binding site, which reduces the enzyme's catalytic activity by preventing the substrate from binding to the active site.

Reversible inhibitors bind to enzymes by non-covalent interactions such as ionic bonds, hydrogen bonds, and hydrophobic contacts. Reversible inhibitors do not conduct chemical reactions when they are linked to an enzyme and are quickly removed by dilution or dialysis.

However, irreversible inhibitors usually covalently change an enzyme, making it impossible to reverse inhibition.

Therefore, the correct option is A.

The bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.

The population of bug decrease because the invasive plants reduce the population of native plants on which the bug feed. If the food for the bug decreases then the population of the bug is also decreases.

So we can conclude that the bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.

The best explanation for the change in the bugs after the introduction of invasive plants is that bugs with longer mouthparts have a survival advantage.

Natural selection is the process by which individuals of a population that are better suited to their environment are more likely to survive and reproduce.

According to this question, a population of bugs have experienced an increment in the following features:

This suggests that the bugs have become more adapted since the introduction of the invasive plants to enable them survive, hence, they developed longer mouthparts and body length.

In systemic circulation, a drop of blood that is rich in oxygen in the left atrium will first travel through the bicuspid valve to reach the left ventricle. From there it will be pumped through the aortic semilunar valve to reach the aorta which will branch into arterioles.

The blood exiting the capillaries is poor in oxygen and will first travel in venules, which will fuse into bigger veins. Eventually the blood will enter into the right ventricule via either superior vena cava or inferior vena cava.

This involves blood vessels supplying oxygenated blood to and returning deoxygenated blood from the tissues of the body.

Answer:

Genetic engineering is deliberate modification of genome to gain desired traits.

The main steps of genetic engineering:

Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.

Answer:

C. The process occurs in the mitochondria of Eukaryotes.

Explanation:

Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.

Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.
