Answer 1
Answer: Good evening Aixa,

An experiment is designed so that you can observe the differences between the experimental group and the control group.

The experimental group is the group of specimens you're exposing to the experiment and the control group is a separate group of specimens that is not being exposed to the experiment, but are also being observed.

-Hope this helps!

A cell turns glucose from thefood we eat into energy for our
body to use. What cell function
does this describe?


Answers

Answer:

\boxed {\boxed {\sf Cellular \ respiration}}\n

Explanation:

The process of cellular respiration occurs in the mitochondria of cells. It goes through 3 stages: glycolysis, the citric acid/Krebs cycle, and the Electron Transport Chain.

The equation is:

C_6H_(12)O_6+6O_2 ->6CO_2+6H_2O+38 \ ATP

In this aerobic process (requires oxygen), glucose (C₆H₁₂O₆) from the food animals eat or produced from photosynthesis and oxygen are converted into carbon dioxide, water, and useable energy (ATP).

So, the cell function described is cellular respiration.

Explain how a species can evolve through natural selection.

Answers

Different members of a species may have different traits, and some will be better than others in helping the organism survive. Basically, the traits that help one survive will let it live on to pass that trait to its offspring, but the organisms with traits that make life harder or possible will not live to be passed on.
So with natural selection, NATURe SELECTs the best-fit organisms of a species to live. Over time as the bad traits die off and the good ones prosper, that's them evolving

So in an enviroment the ones with a better adaptations will survive and pass on thier traits to the next generation. If a group of rabits have smaller feet and hop faster than other jack rabbits, then they will survive when chased by predators, and pass on thier traits, while others would get eaten. Over time the generations would have more rabbits with small feet and faster speeds until all rabbits have that trait.  

The type of insects and the stage of the insect's life can give some indication on how long a body has been dead. True False

Answers

In general, no, it is false that the type of insects and the stage of the insect's life can give some indication on how long a body has been dead. 

Answer: True

Explanation:

Forensic entomology is a sub-discipline of forensic science. It deals with the study of insects and their life cycles which are found in close proximity of the dead body. The type of insects grow over the body depends upon the stage of decomposition of the body. Also the life cycle varies depending upon the feeding nature of the immature stages of the developing insect on the dead body. More deformed body by the insects as evident by the colonization of eggs, and other immature stages as well as the mature insects can give indication of the time since death.

On the basis of the above description, the given statement is true .

What do gradualism and punctuated equilibrium have in common?

Answers

Answer:

its A

Explanation:

shorter version :)

Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Therefore, the correct answer is A

Gradualism and equilibrium are two different ways in which the evolution of species can take place.

Further Explanation

Gradualism is a variation that occurs gradually and can be cannot be recognized easily over a short period.  Evidence of gradualism has been found by scientists in the geologic process. Scientists describe gradualism as some of the processes that are going on in earth’s landforms and surfaces. They also pointed out that the mechanisms it contained, erosion, plate tectonics combines the processes that in some aspects appear destructive and others constructive.

Punctuated equilibrium, on the other hand, has to do with the notion that since no changes can be seen in a species, there must however be a period when no changes take place. Punctuated equilibrium maintains that evolution happen in a short burst with a longer period of equilibrium.

One of the scientists that proposed punctuated equilibrium is William Bateson, he argued that species can only evolve rapidly and not gradually. He believed that evolution occurs rapidly in a species with a long period of stability.

Thus, Both Gradualism and punctuated equilibrium are explanations of the rate of evolutionary change. Both are accepted ideas of how evolution occurs in a species.
