Which of the following is a measure of the biodiversity of an ecosystem?

Compared to the amount of genetic information

miskamm [114]

Answer:

c. One half as much.

Explanation:

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that reduces the number of chromosomes in half, generating haploid daughter cells.

0. Summarize the effects of progesterone and estrogen

tino4ka555 [31]

Answer:

Estrogen and progesterone are both involved in preparing the endometrium for embryo implantation. Estrogen helps to ensure conception by increasing the amount of secretory glands in the uterus. Estrogen also increases blood supply to the endometrium.

Progesterone is crucial for embryo implantation and maintenance of pregnancy. Progesterone also enlarges secretory glands that produce carbohydrates, proteins and mucin that are required for embryo nourishment before implantation. Progesterone stabilizes endometrial muscles to prevent them from contracting during pregnancy.

Explanation:

Estrogen and progesterone are steroid hormones of the reproductive system. Estrogen helps in conception whereas progesterone maintains pregnancy.
Estrogen is secreted during the follicular phase of the menstrual cycle that promotes the growth and maturation of follicles in the ovary.
Estrogen also induces oestrous behavior in females.

Secreted by the corpus luteum, progesterone is also a steroid hormone, responsible for implantation of the embryo in the uterus.

What are 2 real life examples of cytoplasm?

s344n2d4d5 [400]

Cytoplasm is the thick fluid solution that fills each cell and is enclosed by the cell membrane. It is made up mostly of water, salts, and proteins.

The cells within your own body, and within plants contain cytoplasm. So two real life examples of cytoplasm would be the fluid in your own cells, and the fluid inside the cells of a tree.

A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants. Whi

Gnom [1K]

The provided question was incomplete as it lacks the options. However, the correct option for this question is as follows:

an electronic balance to measure the volume of soil in which each corn plant is grown

a graduated cylinder to measure 30 mL of water for each plant daily

a metric ruler to determine the mass of each plant each week

a Celsius thermometer to determine the pH of the soil

Answer:

The correct answer is - a graduated cylinder to measure 30 mL of water for each plant daily

Explanation:

The basic knowledge requires to answer this question, as it is not asking about the photosynthesis or temperature of the air but the tool which is correctly matched, so let's get the answer from the options:

the first option is talking about the electric balance and measuring the volume of soil with it, as wee know electric balance measures mass or force on the pan downwards which is the mass of the substance. so it is an incorrect match.

Graduated cylinder to measure the 30 ml water which is correct as this tool measure volume of liquid or substance.

A metric scale measures distance or length of an object, not the mass thus, it is an incorrect match.

A thermometer measures the temperature, not the pH of a substance so it is also an incorrect match.
