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.
D) Contour plowing is used to reduce erosion and sediment pollution.
Explanation:
Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.
Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.
- The rate at which rain water and precipitation moves along slope terrain is very fast.
- This causes the washing off of the the topsoil on hills to eroded very fast.
- Contour plowing breaks the slope and farming is done along movement on the contour.
- This prevents topsoil erosion.
- It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.

Answer:
Zooplankton(A)
Explanation:
Because the toxic mercury builds up in the bigger organsims
Answer:
d.
Explanation:
Pruning is the process by which unused connections between neurons are eliminated. This has been studied and scientists believe this process takes place in order to get rid of any damaged or degraded neurons, allowing specific areas of the brain to improve their networking ability. Which is why it is a big area of study in regards to child development.
