Scientific investigations often lead to the formulation of new scientific questions. The observations Charles Darwin made during

his time aboard the H.M.S. Beagle prompted him to ask which question?
Do living organisms change over time and, if so, how?
Are the finches of the Galapagos Islands the same as those on the mainland?
Can selective breeding occur in nature?
Can the accumulation of gradual changes in a population lead to a new species over time?

The production of egg and sperm cells follows a certain sequence of events.
Maru [420]
The production of egg and sperm cells follows a certain sequence of events.

The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.

Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.

Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
uranmaximum [27]

Answer: the factors that increase cardiac output include:

--> Nervous stimulation and

--> Hypertrophy of the heart.

Explanation:

Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:

--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:

• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.

• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.

--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.

Vladimir79 [104]

Out of the following choices given;

A) II only

B) I and III only

C) I, II, and III

D) I and II only

The answer is B. Cells spend most of their life cycle in the interphase stage.  It is during this stage that the cells prepare itself for mitosis. Interphase of a cell cycle is divided into the G1, S, and G2 stages. The DNA duplicates in the S phase while growth of the cell occurs in the G1 and G2 stages.
