Marianna [84]

Answer:The image to this question is attached.

Answer is the ovary

Explanation: the process by which egg is produced is called oogenesis. It involves the mitotic division of the primodial germ cells to from a oogonia. The oogonia becomes enveloped by follicle cells . Oogonia grows to become the primary oocyte. Each primary oocyte is diploid. It then undergoes the first meiotic division to form the secondary oogonia and a smaller polar nody. all this process of development occurs in the ovary.

After it is released from the ovary, fertilization occurs and it undergoes the second meiotic division to from a polar body and an ovum.

The primary oocyte however remains in prophase of meiosis l throughout childhood.

Think about how acids and bases would affect the water quality in the two lakes. which set of ph data would you expect to see ba
myrzilka [38]

Water first-rate has significantly laid low with the presence of acid and base within the water. So answer is lake a: ph = 6.6; lake b: ph = 6.8.

The water isn't always precise for fitness whilst its exceptionally acidic or exceptionally basic. If the pH of water is almost impartial, this water is nice for consuming purpose. In the choice 3, each lake A and lake B has pH almost impartial so this water reasons no awful impact at the fitness of the human body. Highly acid water has low water first-rate because of the presence of metals which adversely have an effect on our body.

<h3>What is pH of lake water ?</h3>

The pH degree of the water in rivers, lakes, and wetlands is critical to plant and animal life is 7.

Hence explained.

AlexFokin [52]

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

How high can creatinine and bun levels go before death?
wel
Creatinine is a by-product of muscular metabolism. In the natural and normal scheme of things, this substance or waste product can be eliminated from the body. A high-serum creatinine level may cause kidney damage. In relation to the above question as to how high can creatinine levels go before death, it must be noted that kidneys have strong compensatory ability and by that as long as its still 50 percent functional, creatinine level won't be that high. Which leads us to a conclusion that, the lesser the kidney function level is, the higher the creatinine level.

On the other hand for the blood urea nitrogen (BUN) is the most stable blood constituent following death as it reaches antemortem (before death) levels and even after moderate decomposition.

Therefore, as long as the kidneys are functional, regardless of other factors such as the patient's condition/ diagnosis, these blood constituents are nearly normal.
