Help muh please I will give Brainliest

Answer:

Earth is not heated in a uniform manner, there are hit and cold spots, e.g you have a desert inland the Sun heats it, hot air rises. Since there can't be a vacuum, colder air from the surroundings must fill the gap, then you get convection.

Explanation:

Explanation:

the answer is B. Convection currents drive atmospheric circulation at the global scale. The Earth is heated most intensely near the equator, where this air rises as part of the intertropical convergence zone. It then reaches high altitudes and diverges poleward as part of the Hadley cell, a permanent circulation cell in the tropics. This is the primary means in which excess energy is transported poleward via the atmosphere. This air and its energy tends to subside in the subtropics, and eventually move poleward again in the Ferrel cell of the mid-latitudes and polar cell of the polar regions through eddy diffusion.

Mitosis is a type of cell division that produces cells that are identical to the parent cell. Meiosis is a different type of cell division that produces cells that carry half the genetic material of the parent cell.

Based on the information provided, how do the purposes of mitosis and meiosis differ?
A.
Mitosis produces cells used for growth and repair, while meiosis produces cells used for reproduction.
B.
Mitosis is only used by single-celled organisms, while meiosis is only used by multicellular organisms.
C.
Mitosis creates cells used for reproduction, while meiosis produces cells used for growth and repair.
D.
Mitosis is only used by multicellular organisms, while meiosis is only used by single-celled organisms.

Evolutionary theory predicts that related organisms will share similarities that are derived from common ancestors. Which of the following CANNOT be concluded from the fossil evidence?

OPTIONS

The chronological sequence in which different organisms first appeared.

Evidence of every species that has ever existed

Links between groups leading to various modern species

Relation through common descent from older organisms

For how many two-digit primes is the sum of the digits equal to 8?

Which of the following best describes how an observation of the fossil record supports the theory of evolution?

OPTIONS

Hard parts of animals, such as bone and teeth, are much more likely to become fossilized than other parts made of soft tissue.

The fossils found in rock layers of different ages are related to, but different from, fossils found in rock layers above and below.

The fossil record has many more examples of organisms that lived in water where their remains were more likely to be buried quickly.

Close examination of fossils can reveal details and the diet, environment, and even behaviors of the organisms the fossils represent.

What changes in adaptations would you most likely see over many generations if a species of plant that is adapted to a warm, dry climate was moved to a very wet climate?

C. The leaves would become small.
D. The seeds would become winged.

Read the excerpt from The Mother of America:

Martha Washington's promotion of democratic values as America's original first lady also proved her worthy of the name "Mother of America." She realized that the way she treated the role of first lady would set precedents for future women. Martha had to figure out how to create an atmosphere that reflected democracy and commanded respect from the rest of the world. To accomplish this, she held a reception once a week where different people could enjoy refreshments and exchange ideas. Unlike other events, Martha's reception was representative of democracy, as it was open to different groups of people, including both men and women. Overwhelming respect for Martha led to others calling her "Lady Washington." Despite praise for her work, Martha disliked the restrictions put on her as the first lady and missed her son. In spite of these concerns, Martha did her duty and remained to support the president and her country. Her role in defining America's first lady—the figurative "Mother of America"—was invaluable.

Martha attempted to establish a democratic tone that also invited respect from other nations. She missed her son greatly but continued to fulfill her duties as first lady and representative of America.
