The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.

Answers

Answer 1

Answer:

It's active transport

Explanation:

Answer 2

The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.

What do you mean by Ion uptake?

Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.

Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.

Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.

Imagine for a moment that a large artery formed two branches carrying blood to two different organs. Branch 1 has a radius of 0.5 cm and Branch 2 has a radius of 1.0 cm. If the blood flow rate in Branch 1 is 2ml/min, what do you expect the blood flow rate of Branch 2 to be

Answers

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

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

Answers

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:

Calcium flows into the presynaptic terminal.The calcium makes the vesicles (with neurotransmitters) descend and fuse with the terminal membrane to release the neurotransmitters to the synaptic cleft.

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

mendel’s law of segregation states that the two alleles for each gene separate during gamete formation. during which stage of meiosis do the alleles separate?

Answers

anaphase (the chromatids pull apart to opposite ends)

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

What is meiosis?

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.

Explanation:is correct. post protected

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

What is ovulation?

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.
