When arginine is added to a culture already growing exponentially in a medium without arginine, what occurs?.

Answer:

Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.

All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.

The formation of gametes for a dihybrid involves the crossing of the two traits involved.

Thus: Aabb is equivalent to crossing Aa and bb

                           Aa   x   bb

                       Ab   Ab   ab   ab

Hence, all the gametes would be Ab or ab.

For AABb:                     AA   x   Bb  =   AB   Ab   AB   Ab

The gametes are either AB or Ab

For AaBB: the gametes are either AB or aB

For AAbb, only Ab gametes are produced

For AaBb: the gametes would be AB  Ab   aB and ab

For aabb: only ab gametes are produced.

Information about the four organisms can be found on the Internet. Use credible websites to find answers to the questions you developed in part A. Based on this data, draw your own dichotomous key. Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.

Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms. For example, Does the organism have cells? would be an inappropriate question, because all the organisms have cells.

When the tubular fluid leaves the distal convoluted tubules, it must travel through a series of small collecting tubules that empty into the collecting duct.

The structures described in the question are a part of the organ in charge of filtering the blood and producing urine, the kidney. Within the kidney, the filtered plasma, in the form of urine, travels through a series of tubules and ducts in order to reach the ureter.

Therefore, we can confirm that when the tubular fluid leaves the distal convoluted tubules, it must travel through a series of small collecting tubules that empty into the collecting duct.

An error is to describe arteries as the vessels that always transport oxygenated blood instead of describing them as vessels that take blood away from the heart.

An artery is a big blood vessel that transport enriched oxygen blood to all part of the human body.

This rich oxygen blood is used by human tissues to carry out cellular respiration (aerobic cell respiration).

Moreover, veins are other types of blood vessels that are also capable of carrying blood toward the heart.

Explanation:

Water’s density increases as it freezes or at lower temperature which is a unique property of water that enables aquatic animals to survive.

Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.

So we can conclude that cold water is more dense and will sink in room-temperature water.
