Answer:
D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.
Explanation:
Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.
However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.
Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
The hereditary form of hypertension is detected when the adrenal gland produces too much aldosterone.
<u>Explanation:</u>
Hypertension is an important risk factor for several cardiovascular disease. If prolonged it damages the blood vessels causing malfunctioning of the heart, kidneys and brain. Hypertension can be caused due to various genetic or environmental factors.
There are cases where familial hypertension are detected. This is caused due to the mutation in a single gene which is passed on to the generations where even in young age the children are seen affected with hypertension.
This in medical terms is termed as familial hyperaldosteronism type II. This is occurred due to the mutation in CLCN2 gene. It tends to produce too much of aldosterone hormone which causes high blood pressure.
Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
<span>Letter A is the answer. Almost all plant cells have single large central vacuole. These large central vacuoles of the plant cells are filled with water and can take over 80% of its cell volume. This is surrounded by a single membrane called tonoplast. The role of the central vacuole is maintaining the plant cell's pressure.</span>
