1. Describe how radio telescopes are used to explore space.

Answers

Answer 1
Answer:

Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.

Answer 2
Answer:

Answer:

Radio waves from space are sensed by a giant parabolic reflector which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space.

In the image, two cookies are used to model tectonic plates. Which plate boundary does this model represent? A.) Convergent Boundary

C.) Transform boundary

D.) none of these

Answers

The correct answer is the divergent boundary.  

A divergent boundary, in plate tectonics refers to a linear characteristic, which prevails amid the two tectonic plates that are moving away from each other. The Mid-Atlantic Ridge and the Great Rift Valley are the examples of divergent boundaries.  

Iceland is an illustration of a country going through a continental divergent boundary. The Mid-Atlantic Ridge differentiates Iceland and is the boundary between the Eurasian and the North American tectonic plates.  


Answer:I believe the answer is C. Transform plate boundary. Search up three of the names and see how they look and compare it to the picture up above.

Are the offspring of parents who are both homozygous dominant for normal red blood cells in danger of getting sickle-cell anemia?

Answers

Answer:

If both parents do not have sickle-cell anemia, than the possibility is low.

Explanation:

If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.

If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.

When both parents have sickle cell anemia, their child will definitely have it.  

Answer:

No, 0% chance

Explanation:

none of the parents are carriers of this disease, and are homozygous dominant to the normal red blood cells, so they will not inherit this disease

What mutation is harmful to the organism?

Answers

Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts and digestive organs.

What is a positive effect that predators have on a prey population?A.

C.
They eliminate the prey population in order to maintain competition over resources such as food and water.

D.
Prey are able to increase their populations and use of food, shelter, and water when predators are on the hunt.

Answers

A. They keep the prey population low so they will be less likely to deplete resources such as food, water, and shelter.
