Len [333]
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.

Which best describes oogenesis and spermatogenesis?
pochemuha
The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>

Why is exponential growth usually very rare in nature
olchik [2.2K]

Answer:

Explanation:

The scarcity of natural examples is due to the fact that there are population controls due to a limiting amount of resources such as food, light, shelter, water as well as to factors such as predation, climatic change, and disease.

juin [17]

Incomplete question. The remaining part of the question read;

Words in the left column:

  • Yes
  • No
  • Observational
  • Manipulative

1. A physiologist incubates eggs in the lab at a range of temperatures to see what temperatures produce males and what temperatures produce females.

2. A biologist predicts that shade might influence ground temperature, and therefore turtle sex ratios. He records the sex ratio of turtle hatchlings in shaded and unshaded regions

3. An ecologist predicts turtles grow larger when no predators are around. She places turtles in an experimental pond system where half the ponds have predators and half the ponds have had the predators removed.

4. A climatologist predicts that concentration of CO2 in a city will be negatively correlated with the amount of wind in that city. He collects data and looks at the amount of CO2 in a city as a function of the wind speed in the city.

5. A sociologist conducts a survey in Hawaii to describe people's attitudes about global climate change.

6. A scientist determines the average wind speed, and variation in the amount of wind, in a number of locations to see which locations would be most suitable for wind turbines

<u>Answer/Explanation:</u>

1. <u>Hypothesis-driven?</u> Yes!

<u>Observational or Manipulative?</u> Observational.

We can make this conclusion here that the physiologists' research is hypothesis-driven since we are told he wanted to <em>"see what temperatures produce males and what temperatures produce females." </em>In other words, he wanted to know whether the temperature used in incubators can influence the sex of an egg by means of observation.

2. <u>Hypothesis-driven?</u> Yes!

<u>Observational or Manipulative?</u> Observation.

3.  <u>Hypothesis-driven?</u> Yes!

<u>Observational or Manipulative?</u> Manipulative.

We can make the conclusion that is the ecologist used the manipulative method in her research since she decided to place the turtles in two different types of ponds; one where half the ponds have predators while in the other the pond the predators have been removed. In other words, she manipulated the independent variables.

4. <u>Hypothesis-driven?</u> Yes!

<u>Observational or Manipulative?</u> Observational.

Note, the use of the word, "predicts" in most instances underscores the tone of hypothesis-driven research, hence we can say Yes! And remember, we are told the researcher "collects data", meaning he is merely observing differences that occur naturally.

5. <u>Hypothesis-driven?</u> No!

<u>Observational or Manipulative?</u> Observational.

<u>6. Hypothesis-driven?</u> No!

<u>Observational or Manipulative?</u> Observational.
