Which pathway represents the most common sequence of information flow through a neuron?
love history [14]

Answer:c. Dendrite → cell body → axon hillock → axon

Explanation:a neuron has many cytoplasmic extensions called dendrites.the dentrites enter into the cell body at one end . the cell body also leads to axon at the other end, which extends toward another dentrite.axon hillock connect the axon to the cell body.

Impulses are usually transmitted along the neuron in one direction.

From the dendrites to the cell body,to the axon hillock and then to the axon.

The nurse is caring for a 10-year-old child who weighs 82.2 lb (37.3 kg) and is to receive 2.5 ml/kg/hr of 0.45% nacl solution.
Vitek1552 [10]

Answer:

The correct answer would be 93 milliliters.

The same can be explained with the help of the unitary method.

The volume of solution required for 1 kg of weight in one hour = 2.5 milliliters (given in the question).

Thus, the volume of the solution required for 37.3 kg of weight in one hour = 2.5\times37.3 milliliters

It comes out be 93.25 milliliters.

Thus, around 93 milliliters of the solution should be given to the child of weight 37.3 kg in one hour.

Why does photosynthesis require water? a. because water provides oxygen atoms. b. because water provides electrons . c. because
katovenus [111]

Answer:

The correct answer would be b. because water provides electrons.

During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.

The overall reaction can be written as:

2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂

It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.

The oxygen is released as the byproduct of photosynthesis.

The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).

The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.

The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.

The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.

A single-stranded DNA molecule has the sequence TCAACTTGA. The equivalent sequence in an RNA molecule would be ________.
Black_prince [1.1K]

Answer:

UCAACUUGA

Explanation:

Since the question is asking for the <u>equivalent</u><u> </u><u>sequence</u> and not the complementary sequence, this is the answer. Thymine (T) base pairs are replaced by uracil (U) in RNA.

If the question were asking for the <u>complementary</u> RNA sequence, then your answer would be AGUUGAACU.
