How does a radio use radiant energy

Answers

Answer 1
Electromagnetic waves carry energy
Answer 2

Answer Explanation:

A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.

When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.

Explain why you cannot draw a conclusion about the effect of one variable in an investigation when the other variables are NOT controlled.

Answers

Answer:

Because you don't know which variable caused the effect.

Explanation:

It's always important to have a control because you need to be able to pinpoint exactly what variable caused the specific effect to take place. This is also why multiple variables can not be tested at once.

What would occur if a nitrogen base in the RNA strand is mis-matched? How would that affect the protein? How could that affect the organism?

Answers

Answer:

Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer.

In mismatch repair, mistakes that happen during DNA replication are recognized, cut out and replaced. ... This mismatched base pair causes a point mutation, which you can think of as a typo in the DNA sequence of the new strand.

Explanation:

Incorrectly paired nucleotides cause deformities in the secondary structure of the final DNA molecule. During mismatch repair, enzymes recognize and fix these deformities by removing the incorrectly paired nucleotide and replacing it with the correct nucleotide.

Eukaryotes have solved the end-replication problem by locating highly repeated DNA sequence at the end, or telomeres, of each linear chromosome. In humans and other vertebrate organisms, the sequence of nucleotides in telomeres is TTAGGG, is repeated between 100 and 1000 times.

Which phrase describes organisms that formed index fossils?
(a) Are extinct
(b) Had soft parts
(c) Were generally large
(d) Lived in a narrow geographic area​

Answers

Answer:

A.) Are extinct

You should mark me brainliest because I think I'm cool

Options (1), (2), and (4)

Index fossils are usually defined as those fossils that were present on earth for a very short period of time. They were very broadly distributed in almost all parts of the world. They were comparatively smaller in size and comprised of hard parts that were preserved under favorable conditions which are found at many places in the present. These are extinct species. For example, trilobites and ammonites.
These index fossils are very useful because it helps in determining the age of the fossils as well as rocks by applying the radioactive dating method.
thus, the correct answers are options (1), (2), and (4).

A particle of rain water has just reached the ocean. In what order will the particle now complete the following steps of the water cycle?

Answers

Evaporation will probably be the next step. The water cycle consists of a few steps. Most of which you should know. But yeah evaporation would most likely be next.

Answer:

evaporation - condensation - precipitation - surface runoff

Explanation:

For a water particle that has just reached the ocean, the correct order of the water cycle is as follows: evaporation (liquid water changes to water vapor) → condensation (water vapor changes to liquid water) → precipitation (water falls to the Earth's surface) → surface runoff (water travels along the surface of the Earth into a reservoir, such as an ocean). The water cycle is a continuous cycle with no strict beginning or end.

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.

Answers

Answer:

See the answer below

Explanation:

From the illustration of the experiment, the question that Carson can best answer  is that "Do bananas develop more brown spots if they are kept in bags with holes  compared to bags without holes?"

The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.

Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes.

Which effect does the sun's energy have on a comet?
A. It causes the comet to form a bright tail.
B. It causes the core of the comet to melt.
C. It causes the comet to turn toward earth.
D. It causes the comet to break apart.

Answers

Answer:

The answer is B because the sun melts the core of the comet

The sun's energy causes the comet to form a bright tail. The correct answer is A.

When a comet approaches the Sun, the Sun's energy causes various effects on the comet.

As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.

This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.

Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.

So, the correct option is A.

Sex-Related inheritance: X chromosome; Non Sex-Related inheritance​

Answers

What we already know:

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex. That means that the gene codes for more than just the sex.

Building on that knowledge:

Sex-Related Inheritance that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas Non-Sex-Related Inheritance is carried on the other thirty chromosomes that the individual also carries.

Sex-Related inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

Vocabulary:

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?

Answers

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

How do the circulatory and nervous systems work together to maintain homeostasis | ASAP

Answers

The cardiovascular system helps maintain homeostasis by continually supplying the central nervous system--the brain and spinal cord--with oxygen and glucose. Brain cells start dying after just one minute without oxygen. The brain is the control center for all of the body's homeostatic processes.

Answer:

The circulatory and the nervous systems work together to maintain homeostasis because the circulatory system gives your brain a lot of oxygen and glucose while your brain regulates your heart rate and blood pressure. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain  homeostasis.
