Human females produce egg cells through a process called oogenesis. This process involves stages of meiosis and maturation. Only a small number of egg cells will actually mature and be released during a woman's reproductive years.
Human females produce egg cells through a process called oogenesis. Oogenesis begins during fetal development, where billions of egg cells form in the ovaries. However, only a small number of these cells will actually mature and be released during a woman's reproductive years.
Oogenesis is a complex and regulated process that involves several stages. The primary stage is called meiosis, where the chromosomes in the developing egg cell undergo DNA replication and cell division to create haploid cells with half the number of chromosomes. These haploid cells are then referred to as secondary oocytes. The secondary oocytes undergo further maturation and, when fertilized by a sperm cell, can develop into a human embryo.

Answer:
Glucagon hormone from pancreas serves to raise the blood glucose level.
Explanation:
The glucagon hormone from pancreas is secreted under the conditions of lower blood glucose level. The hormone stimulates break down of glycogen into glucose to increase the blood sugar level. On the other hand, insulin hormone from pancreas serves to raise the blood glucose level when it is dropped below the normal range.
supported by an ecosystem?
Answer:
umm chile
Explanation:
me dont understand because im slow
In order to increase the rate of photosynthesis in a plant, a plant should be developed with many broad leaves. The broad leaves will have increased surface area and more chlorophyll. The increased number of the leaves in the plant will also contribute to the overall increased rate of the photosynthesis.
A strong and thick stalk will support the plant but will have no effect on the rate of photosynthesis. Narrow leaves will decrease the photosynthesis rate. Bright flowers will aid in pollination via the honeybees but not increase the photosynthesis rate.
Hence, the correct answer is 'many broad leaves'.
prop the trees up above the water line
b.
excrete excess salt
c.
absorb carbon dioxide from the air
d.
none of the above
Correct answer: A). Prop the trees up above the water line
Mangrove pneumatophore is the specialized root structures that are known to grow out of the water surface and help in the respiration of mangrove plants. They allow the collect oxygen from the atmosphere.
It mainly grows in mud and there the conditions are anaerobic means lack of oxygen. Oxygen is necessary for their survival that is done by the mangrove pneumatophore roots.
Hence, the correct answer would be option A.
Mangrove pneumatophore roots mainly prop the trees up above the water line to intake necessary oxygen from the air for survival, but they do not practically absorb carbon dioxide from the air.
Mangrove pneumatophore roots have a distinctive function in the survival of Mangrove trees in their saline, oxygen-poor environments. The correct answer to your question is that mangrove pneumatophore roots indeed prop the trees up above the water line (option a). These roots emerge from the water, allowing Mangrove trees to intake the necessary oxygen for survival. While they also partake in the limited excretion of excess salt, their main function is undeniably oxygen absorption from the air and supporting their physical structure.
However, the roots do not absorb carbon dioxide from the air (option c). Thus, although options a and b reflect partial truth, option a accurately captures the characteristic function of pneumatophore roots.
