"In humans, five days after the fertilization, the blastocyst performs zona hatching; the zona pellucida degenerates and decomposes, to be replaced by the underlying layer of trophoblastic cells. The zona pellucida is essential for oocyte growth and fertilization."
The zona pellucida supports communication between oocytes and follicle cells during oogenesis; protects oocytes, eggs, and embryos during development, and regulates interactions between ovulated eggs and free-swimming sperm during and following fertilization.
Answer:
Calvin cycle is the term which is used for the process by which the light reactions of photosynthesis produce energy in the form of Adenine tri phosphate (ATP).
Explanation:
Calvin cycle is an important phase of photosynthesis which consists of two stages. In the first stage, ATP and NADPH are produced from chemical energy in the presence of sunlight. In the second stage, water and carbondioxide combines with each other forming glucose molecule.
Answer:
Organisms depend on other members of an ecosystem to live and grow. For example, in a symbiosis, buffalo birds will lay eggs in the nest of other birds. These chicks then depend on the parent birds to raise them.
Explanation:
For Anna’s case, my preliminary idea of the species of bacteria
responsible for Anna’s infection is a Gram-negative bacterium as observed in gross examination of the
colony. With this, my <span>idea has not changed since the last activity for the bacteria was
rod-shaped when we view it through a
microscope and the color of the colonies was
pink after we Gram stained it, which indicate that it is Gram-negative.</span>
