A zoology student is investigating whether it is true that the gender of turtles depends on the temperature at which the turtle eggs are kept before they hatch. He will test if turtle eggs incubated at 29–30 degrees Celsius produce females, and eggs at 24–26 degrees Celsius produce males. What is the independent variable?

Answers

Answer 1

Answer: The independent variable is the temperature. Independent variable refers to the variable in an experiment that can be changed by the scientists or the one making the experiment. A good experiments has a single independent variable and the changes observed will be the dependent variable. In this case, the dependent variable is the gender of the turtle.

Which of the following is a true statement about tectonic plates?a.they located in the molten layer beneath the earth first.
b.all tectonic plates are located at the earth's core
c.they're located approximately 10 meters below the surface of the ocean.
d.all of the earths landmass rests on tectonic plates.

Answers

The true statement is - d. all of the earth's landmass rests on tectonic plates.

The Earth’s lithosphere is a rigid outer part of the earth comprise of crust and top or upper mantles. The lithosphere is made up of tectonic plates. It constitutes all floor plates including oceanic floor plates and continental plates.

The tectonic plates are present on the top of the hot molten layer of the mantle.
It starts at the seafloor of the ocean.
As it is the part of the lithosphere it all landmasses rest on tectonic plates
Tectonic plates contain sediments that contain information about the Earth’s history

Thus, the true statement is - d. all of the earth's landmass rests on tectonic plates.

I would go with D as it is closest to correct. Every part of the surface of the Earth is a tectonic plate though. The plates vary in thickness, but all of the surface of the Earth is made up of tectonic plates, including the parts under the ocean. Technically, the Earth's landmass does not rest on the tectonic plates, it IS the tectonic plates, but it is the closest to correct here in my opinion.

Steroid hormones ________. begin their action outside the membrane usually diffuse through the plasma membrane into target cells bind to receptors in the plasma membrane are water soluble

Answers

Steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.

What are Steroid hormones?

Steroid hormones may be defined as a type of hormones that are synthesized in the adrenal cortex, the gonads, and the placenta. They are all derived from cholesterol and many are of clinical importance. Steroid hormones are synthesized in the mitochondria and smooth endoplasmic reticulum.

According to the context of this question, lipid-derived (soluble) hormones such as steroid hormones diffuse across the membranes of the endocrine cell. Once outside the cell, they bind to transport proteins that keep them soluble in the bloodstream.

Therefore, steroid hormones usually diffuse through the plasma membrane into target cells. Thus, the correct option for this question is B.
