The circulatory system includes which of the following? a. the heart only c. the heart and the brain b. the heart and blood vess
Arisa [49]
The answer should be C, the heart and the blood vessels.

The heart acts as a pump in the circulatory system. It pumps blood to organs and tissues all around the body. Meanwhile, the blood vessels (arteries, veins, and capillaries) help transport the blood to tissue and cells and back to the heart. Each type of blood vessel has their own function.

The brain is not involved in this system, as the whole circulation process does not require any us to make any decision.

In addition, there's also one structure that is in the blood vessels, but technically not another item for the circulatory system. That's valves, they are like flaps that ensure blood flowing in one wag direction and to prevent the back flow of blood.

So, the answer is C.

Why is photosynthesis an example of a chemical reaction, and why is it classified as endothermic? (2 points)
Elan Coil [88]

Photosynthesis is an example of a chemical reaction <u>because it is a process in which carbon dioxide and water are combined to form glucose and oxygen.</u> It is an endothermic reaction because <u>it requires solar energy. </u>

<u> </u>

Further explanation:

Photosynthesis is the process by which green plants and some organisms convert solar energy into chemical energy. This <u>process takes place in the chloroplast</u> of the cell. Chlorophyll is the green pigment found in the chloroplast that helps in the absorption of sunlight. The plants use this <u>light energy to transformed carbon dioxide and water into glucose and oxygen.</u> This process is known as an endothermic chemical reaction.

The tiny pores present on the surface of green leaves help in the exchange of gaseous such as carbon dioxide enters the plant for the process and oxygen is removed from the plant after the process is completed. These tiny pores are called stomata. Glucose is the end product of photosynthesis which is utilized by the plant as a source of energy. It helps in the growth and development of the plant. The remaining sugar molecules are combined to form a complex substance called carbohydrate.

<u>The complete process occurs in two steps: light-dependent reaction and light-independent reaction</u>. The light-dependent reaction occurs in the thylakoid membrane in the presence of solar energy. The light-independent occurs in the absence of solar light or usually in the dark. It occurs in the stroma of the cell. It is a carbon fixing reaction in which sugar molecule is produced.

Which condition is necessary for a mold fossil to form
Sindrei [870]
First, the organism needs to be buried quickly so the bones do not rot, sinking in tar, sand storm sinking in mud etc. Over time more sediment will cover the organism, preventing decay. Being buried quickly and preserved away from predators are one of the reasons why marine life fossils are much more common <span>the terrestrial animals as they are rarely preserved.</span>

Natural selection in a population leads to evolution when:
Phoenix [80]
D) allele frequencies of some traits change in the population

Alleles can be phenotype (how they appear) and natural selection is when an organism changes in a way that helps them survive.

It can be the way their beaks are formed that gives them a better chance of catching food among other stuff (Darwin's investigation)
Or how they change their color to adapt to the sudden change in tree coloration (Pepper moths)
