Answer: flows INTO the synaptic knob.

When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows into the synaptic knob.

In a neuromuscular junction, there are three parts. They are the presynaptic terminal or synaptic knob, the synaptic cleft and the postsynaptic terminal. The calcium ions will work in the synaptic knob when the nerve impulse arrives.

Once that the nerve impulse reaches the end of the axon, it will affect the presynaptic terminal. In there, it causes the opening of voltage-gated calcium channels. As a result:

In conclusion, the nerve impulse causes the opening of voltage-gated calcium channels, and calcium flows into the synaptic knob.

Answer:

it increase the genetic diversity through meiosis , crossing over and random assortment of chromosome

Explanation:

There are two main processes during sexual reproduction: meiosis, involving the halving of the number of chromosomes, and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes.

while asexual reproduction doesn't form any reproduction that involves neither meiosis nor fusion of gametes

The flow rate through Branch 2 is 8·√2 ml/min

Reasons:

Radius of Branch 1 = 0.5 cm

Radius of Branch 2 = 1.0 cm

Flow rate, Q = Velocity, V × Area, A

The area of the Branch 1 = π × 0.5² = 0.25·π

We have;

[tex]\dfrac{v_1^2}{r_1} = \dfrac{v_2^2}{r_2}[/tex]

Which gives;

[tex]v_2 = \mathbf{\sqrt{\dfrac{v_1^2}{r_1} \times r_2}}[/tex]

[tex]The \ velocity \ of \ Branch 1 , \ v_1 = \dfrac{2}{\pi \times 0.5^2} = \dfrac{8}{\pi}[/tex]

Therefore;

[tex]v_2 = \sqrt{\dfrac{\left(\dfrac{8}{\pi} \right) ^2}{0.5} \times1} = 8 \cdot\dfrac{\sqrt{2} }{\pi}[/tex]

[tex]The \ flow \ rate, \ Q_2 = 8 \cdot\dfrac{\sqrt{2} }{\pi} \times \pi \times 1^2 = 8 \times \sqrt{2}[/tex]

The flow rate through Branch 2 = 8·√2 ml/min

The structure of DNA resembles a twisted ladder because both strands are linked by hydrogen bonds.

Deoxyribonucleic acid (DNA) is a double helix composed of two long chains of nucleotides linked by hydrogen bonds.

In DNA there exist only four different types of nucleotides (i.e., Guanine, Cytosine, Thymine and Adenine).

In conclusion, the structure of DNA resembles a twisted ladder because both strands are linked by hydrogen bonds.

The stage of meiosis at which the alleles separate is anaphase. The correct option is B.

Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.

It entails two rounds of division, resulting in four cells with only one copy of each chromosome.

Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.

The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.

The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.

Thus, the correct option is B.

b. Ovulation is the release of a mature ovum, which occurs once each month.

Explanation:is correct. post protected

Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.

The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.

Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.

Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.

Thus, the correct option is B.

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.
