Which of the following choices best describes ‘ovulation?'
A. An egg is released from the ovary.
B. An embryo sinks into the uterus lining.
C. The sperm and egg nuclei fuse.
D. The ejection of sperm through the penis.
Answer:
An egg is released from the ovary
Ovulation is a crucial process in the female reproductive system, occurring as a part of the menstrual cycle. It involves the release of a mature egg (ovum) from one of the ovaries. The correct option is A. An egg is released from the ovary.
1. **Menstrual Cycle**: The menstrual cycle is the regular hormonal cycle that occurs in women of reproductive age. It typically lasts around 28 days, although the length can vary from woman to woman. The cycle is divided into different phases, with ovulation occurring during one specific phase.
2. **Follicular Phase**: The menstrual cycle begins with the follicular phase, where hormones, primarily follicle-stimulating hormone (FSH) and luteinizing hormone (LH), are released by the pituitary gland. These hormones stimulate the growth and maturation of follicles in the ovaries.
3. **Ovarian Follicles**: Within the ovaries, multiple tiny sacs called ovarian follicles contain immature eggs. Each month, one of these follicles becomes dominant and continues to grow while others degenerate.
4. **Mature Follicle Development**: As the dominant follicle grows, it secretes estrogen, a hormone that prepares the uterus for a potential pregnancy. The rising estrogen levels also trigger a surge in luteinizing hormone (LH) around the middle of the menstrual cycle.
5. **Ovulation**: The LH surge triggers the final stage of ovulation. It causes the mature follicle to rupture and release the mature egg from the ovary. The egg is swept into the fallopian tube by tiny hair-like structures called cilia.
6. **Fertilization**: The released egg remains viable for about 12-24 hours. If sexual intercourse occurs during this time and sperm are present in the fallopian tube, fertilization may occur. Fertilization is the process where the sperm penetrates the egg, resulting in the formation of a zygote (fertilized egg).
7. **Implantation or Menstruation**: If the egg is not fertilized, it will eventually disintegrate, and hormone levels will drop. This leads to the shedding of the uterine lining, causing menstruation to occur. On the other hand, if fertilization occurs, the resulting zygote will undergo several divisions and travel down the fallopian tube to the uterus, where it may implant into the uterine lining and develop into a pregnancy.
Ovulation is a crucial event in the female reproductive cycle, marking the release of a potential egg for fertilization. It is a key factor in determining fertility and the ability to conceive a child.

Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.
Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.
Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.
In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the _____.
Answer:
The axonal membrane (place as brainliest so others know its correct)
Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the Axonal membrane.
What are Neurotransmitters?Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.
The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.
Some examples of neurotransmitters may include serotonin, GABA, dopamine, acetylcholine, etc.

Explanation:
dna is a double-stranded molecule made up of complementary, antiparallel strands. based on what you know about complementary base pairing, fill in the rest of the details in the figure.
The details in the figure correspond to the elements that the DNA strands have in their ends. Also, they correspond to the antiparallel strand with the complementary bases.
The DNA has two antiparallel strands with complementary bases (thymine, adenine, guanine, and cytosine). That is to say, that T pairs with A and G with C. Also, they have specific elements in their ends.
The 3' strand in its end has a hydroxyl (OH) group.The 5' strand in its end has a phosphate group.There is a complementary strand with its respective nucleotides that will pair with the other strand according to their specific bases (A-T; C-G)
In conclusion, the top left end of the 3' strand has a hydroxyl group, while the top right, the 5', has a phosphate group. The complementary strand will go the other way round, from 5' to 3', so the hydroxyl and phosphate groups would be on the right and the left, respectively. The bottom strand is the complementary one, and it runs from 3' to 5'.
