Prokaryotic cells have _____ DNA than eukaryotic cells and _____ chromosomes.
Yuri [45]

The answer for this question I will say is LESS and CIRCULAR.

https://answers.yahoo.com/question/index?qid=20081120175341AAMbjhd

Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself.

here is some information if you need more evidence follow the link and read the paragraph above!! I hope this helps you a lot!!!

The phases of the moon are caused by the sun is wearing distance from the moon moon’s revolution around the earth moves very dis
Inga [223]

Answer:

October 17, 2019

The Moon, otherwise known as Luna, is the only natural satellite of Earth. It was created 4.6 billion years ago, and it is widely accepted that it was created when Earth collided with a planet-sized object called Theia. It’s the fifth-largest moon in our solar system and is the second brightest object in the sky (after the Sun).

Explanation:

History of The Moon

Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.

The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon’s phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon’s orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that time.

Which statements describe functions of antibodies? Select two options.
vodomira [7]

Answer:

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

Which force primarily acts on a natural or artificial satellite to keep it in orbit around a planet
rjkz [21]

Answer:

Gravity

Explanation:

When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.

By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
