Answers
The digestive system is a major body system affected by blood vessels and heart problems. thus option C is correct.
What is the circulatory system?To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.
Heart and blood vessels problem directly affect the circulatory system. Blood vessel disease (Vasculopathy) The blood arteries that transport oxygen and nutrients throughout your body and eliminate waste from your tissues are affected by vascular disease (also known as vasculopathy). Plaque, which is composed of fat and cholesterol, slows or obstructs blood flow in your arteries and veins, causing common vascular issues.

There is more of a variation in temperatures in cities that are on the coast is ability of water to absorb and release heat. Thus, the correct option is D.
Why are the most extreme temperatures experienced inland away from the coast?Because rock and soil have a smaller heat capacity than water, temperature variance is greater in inland places. As a result, land areas lose and absorb heat at a far faster rate than coastal areas.

What does oxygen poor blood deliver to the

A. carbon dioxide
B. glucose
C. water
D. ATP
Answers
Answer:
A.carbon dioxide
Explanation:
oxygen poor blood means the blood is rich with Carbon dioxide
The oxygen poor blood delivers to the lungs carbon dioxide out of the body organs and cells. Thus, the correct option is A.
What is oxygen poor blood?The heart is divided into two separate pumping systems, which include the right side and the left side. The right side of the heart receives oxygen-poor blood that is deoxygenated blood from the veins and pumps it to the lungs, where the blood picks up oxygen gas from the alveoli and gets rid of carbon dioxide gas.
Deoxygenated blood has less oxygen or it is oxygen-poor and contains is carbon dioxide rich. The right heart pumps this deoxygenated blood to the lungs where it picks up additional oxygen gas.
As the blood travels through body, oxygen gas is used up, and the blood becomes oxygen poor or carbon dioxide rich. Oxygen-poor blood returns from the body to the heart by the superior vena cava and the inferior vena cava, the two main veins which bring blood back to the heart.
Therefore, the correct option is A.

In which squares should the phrase "Green pods" appear?
O A and D only
OB and E only
O A, C, and D only
O A, B, C, D, and E
Answers
The inheritance pattern of pods color in pea plants is complete dominance. H0m0zyg0us dominant and heter0zyg0us plants have green pods. Option C) A, C, and D.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
When you cross an individual who is h0m0zyg0us dominant with an individual who is h0m0zyg0us recessive, the whole progeny among the first generation -F1- will express the dominant phenotype since they are heter0zyg0us for this trait.
However, if you let individuals from the F1 cross with each other, the second generation -F2- will be composed of individuals expressing the dominant and the recessive phenotypes. This is because some individuals are h0m0zyg0us recessive and can express the recessive trait.
According to this information, and based on the attached flowchart, we can assume that,
Parentals ⇒ A (gray square) and B (white square)F1 ⇒ C (gray square)F2 ⇒ D (gray square) and E (white square)Since the F1 is completely gray, we can assume this color identifies the dominant phenotype (green pods).
The cross was performed between plants with yellow and green pods, so they must be h0m0zyg0us individuals (dominant and recessive) and the whole F1 must be heter0zyg0us for the trait. So,
A ⇒ h0m0zyg0us dominant because it is gray ⇒ green pods
B ⇒ h0m0zyg0us recessive because it is white ⇒ yellow pods
C ⇒ heter0zyg0us because it is gray and the product of A x B ⇒ green pods
Now, the F2 is composed of D and E which represent plants with yellow and green pods. This means that there are h0m0zyg0us recessive individuals, and the recessive trait -yellow pods- can be expressed again among the second generation.
D ⇒ h0m0zyg0us dominant and heter0zyg0us ⇒ green pods (gray square)
E ⇒ h0m0zyg0us recessive ⇒ yellow pods (white square)
Now, the phrase "Green pods" should appear i all gray squares. These are A, C, and D.
Option C is correct. A, C, and D only.
