Answer:
Lamellae
Explanation:
Chloroplasts are plant (also found in algae) organelles in which photosynthesis occurs. These structures contain pigments (such as chlorophyll) that have the ability to absorb light energy and convert it to sugars necessary for the growth and development of the plant.
Structure of the chloroplast: They are disc-shaped with outer and inner membranes and intermembrane space between them. Inside the chloroplast there is a fluid-filled space called stroma. Stroma contains membrane discs – thylakoids that are arranged in interconnected stacks called grana. In the thylakoid membrane is chlorophyll and inside the thylakoid disc is the space called the thylakoid space.
Answer is Crescent
When the Moon appears smaller than a quarter, we call it a crescent. When the Moon appears larger than a quarter, we call it gibbous. When the moon is getting bigger (phases New to Full) it is waxing. When it is getting smaller (phases Full to New) it is waning.
Answer:
lungs:
The blood first enters the right atrium.
The blood then flows through the tricuspid valve into the right ventricle.
When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
It then leaves the lungs to return to the heart through the pulmonary vein.
The blood enters the left atrium.
It drops through the mitral valve into the left ventricle.
The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.
Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.
The vena cavas pump blood into the right atrium and the cycle begins all over again.
<span>The statement which accurately describes the phases of the menstrual cycle in humans is : B. FSH in the blood is highest during the luteal phase. Keep in mind that when the luteal phase takes place LH from the anterior pituitary gland stimulates the corpus luteum inorder to produce progesterone. The option C, which is suggested above, is incorrect because ovulation occurs at 14th day of the cycle. </span>
Answer:
<u><em>Active Transport</em></u>
Explanation:
<u><em>active transport
</em></u>
During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
