The serous fluid within the pericardial cavity works to:__.
a. eliminate blood pressure spikes.
b. equalize the pressure in the great vessels.
c. lubricate the membranes of the serous pericardium.
d. slow the heart rate.

Answers

Answer 1

The serous fluid within the pericardial cavity works to lubricate the membranes of the serous pericardium.

The pericardial cavity

The pericardial cavity is a space that is enclosed by the two layers of serous pericardium around the heart.

The pericardium is a thin, two-layered, fluid-filled sac that covers the outer surface of the heart. it is divided into 2 namely:

fibrous pericardium and

serous pericardium.

The serous fluid which is also called pericardial fluid helps to decrease friction between the pericardial layers. This is because, they lubricate the membranes of the serous pericardium.

What is some information about Photosynthesis?

Answers

Answer:

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Explanation:

The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll.

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals.Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.Photosynthesis starts when chlorophyll absorbs energy from sunlight. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.Photosynthesis is very important because almost all living things depend on plants for food. Photosynthesis is also important because of the oxygen it produces. Humans and other animals need to breathe in oxygen to survive.Some living things other than plants also make their own food through photosynthesis. They include certain types of bacteria and algae.

When the color of the light changes, the number of light red kidney beans will also change Write a hypothesis about the effect of the red light on the population. Use the "if . . . then . . . because . . ." format, and be sure to answer the lesson question: "How does natural selection change the phenotypes within a population over time?"

Answers

Answer: If red light is shined on a population of red walking beans then they would not be as red as when started because they need light to survive and red light is present but they reflect it until they need it to survive.

Mutations that naturally occur can change phenotype and if it is beneficial to the species then it will be past on if it is no then it will die before passing it on.

Answer:

Explanation:

Natural Selection is defined as the evolutionary process in which organisms better suited to the environment tend to survive and reproduce.

If red light is shined on the population of red walking beans, then the population of light red kidney beans will increase because they will be camouflaged in the light and would not be able to see. The red light will make the beans invisible to other organisms and animals, which increase the population and survival rate of the beans.

Answer:

D

Explanation:

A and C are so incorrect. The reason why D is the correct answer is because DNA does not determine what gets inherited, just what gets added to the gene pool.

DNA does however control the synthesis of proteins by acting as instructions. Then these instructions are read and carried out by RNA to finally complete the process.

6. Based on the food web above, hunting of sharks by humans has increased in international waters. How
will the increase in humans hunting sharks affect the rest of the food web? (5 pts)

Answers

Answer:

Short term: The fish (that sharks feed on) increase, the aquatic plants decrease

Long term: The fish (that sharks feed on) decrease, the aquatic plants increase

Explanation:

Short term: The fish increase because the sharks that used to feed on them decrease hence they get eaten less. The increased fish eat a lot of plants hence aquatic plants decrease.

Long term: The increased fish will then compete for the few aquatic plants present. Only the stronger fish survive hence most fish starve and die. Less fish means that the aquatic plants are being eaten less thus the aquatic plants increase.
