It’s A forested park in a desert city

An example of a place with a microclimate is a forested park in a desert city. The correct option is b.

What is a microclimate?

A microclimate is a small and distinctive climatic area that can be artificial or natural. It is present in between another big climatic area. Examples are a park, a valley, a part of a city, etc.

A desert is an area where only sand is present because these areas are very dry and very less vegetation is present here. The vegetation is adapted to the desert climate.

A forested park will be a green area that contains trees and animals. The deserted area is different from the forest area. So a forested area will be a microclimate in the deserted areas.

Thus, the correct option is b. a forested park in a desert city.

b. Producing gametes (sperm and egg cells) that
unite inside the female reproductive system.
c. Removing nitrogenous wastes and excess water
from the blood.
d. Producing gametes (sperm and egg cells) that
unite inside the male reproductive system.

Answers

Answer:

b. Producing gametes (sperm and egg cells) that unite inside the female reproductive system.

Explanation:

The "gametes" refer to the sex cells in humans. The female sex cells are called "egg cells" and these are being produced by the ovary. The male sex cells are called "sperm cells" and these are being produced by the testicles. After copulation, there's a probability for the egg cells and sperm cells to unite. They unite inside the female's reproductive system, specifically inside the "fallopian tube."

Georgie believes that a special juice will increase the productivity of his workers. He creates two groups, two workers per group. Both groups are assigned the same task, stapling a set of papers. Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Georgie counts how many stacks of papers each group has stapled. Group A stapled 1,320 stacks while Group B stapled 2,200 stacks. Georgie concluded that the juice was not effective in improving productivity.

How would you improve Georgie's experimental design to produce a more valid conclusion?

Select one:
a. Georgie should use more than two people per group.
b. Georgie should also consider employee attendance as a variable.
c. Both groups should take the juice, just a different amount of it.
d. Georgie should not do this experiment as it has no practical implications.

Why have American's portion sizes become larger in the last decade?

Answers

Answer:

American's portion sizes have become larger in the last decade due to the expanding of food industries and marketing campaigns that tell us to eat more.

Explanation:

The growth of food industries in the last decades to obtain more money in combination with the media influence has led us to eat more, thus why the size of our portions has increased their size.

Another theory states that people always want to eat more, and the industry has only fulfilled this demand, but it is not clear why, in the past, this did not happen.

Answers

Answer:

An arctic fox changes its fur color to blend in with its surroundings

Explanation:

This is a defense mechanism because  when it blends into its surroundings it can hide from its predators and help defend itself

The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.

What is arctic fox?

An arctic fox changes its fur color to blend in with its surroundings and this is a defense mechanism because  when it blends into its surroundings it can hide from its predators and help defend itself.The brown color camouflages the brown fox in the forest.

Adaptation is changing of character of an organism for a short time to survive in severe environmental conditions.The brown color camouflages the arctic fox when the snow melts during the summer. The white color camouflages the arctic fox during the winter.

There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes. Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.

Therefore, The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.

Carbon (C)
Atomic #: 6
Atomic Mass: 12

Answers

Question:  Calculate the number of electrons using the information given. Write the number on the line and then draw the electrons into the Bohr model.

Assuming the atom has a neutral charge, the number of electrons will be the same as the number of protons.  The number of protons is given by the atomic number, 6, so there are six electrons.

The first "ring" of the atom (closest to the center) can take two electrons, so draw two electrons there.  The second (outer) "ring" of the atom can take the remaining electrons, so draw four electrons there.

Atomic mass is irrelevant in this specific problem.

If at any given time the Earth's axis was not tilted with respect to the plane of its rotation, the weather would be approximately the same throughout the world. So, the correct option is (D).

What is Rotation of Earth?

Earth's rotation or Earth's rotation is defined as the rotation of the planet Earth around its own axis as well as the change in the orientation of the rotation axis in space, where the Earth rotates eastward, in prograde motion. . As seen from Polaris, the North Pole Star, the Earth turns counterclockwise.

This is the movement of something through one complete circle which the daily rotation of the Earth upon its axis. The Earth's axis runs from the North Pole to the South Pole which takes the Earth 24 hours, or one day, to make one complete rotation around this invisible line.

If the earth's axis was not inclined to the plane of its orbit, there would be no seasons and humanity would have to suffer.

Thus, if at any given time the Earth's axis was not tilted with respect to the plane of its rotation, the weather would be approximately the same throughout the world. So, the correct option is (D).
