The correct answer is A) Chlorophyll absorbs sunlight energy for photosynthesis.
Answer:
The correct answer is c) The first statement is true; the second is false.
Explanation:
To be able to perform its role, a hormone must bind a specific receptor in its target cell. The receptor can be located inside the cell (in cytosol) or in the surface of the cell (transmembrane receptor). By regulating the expression of the receptor, the target cell regulates the hormonal activity.
The number of hormone receptors in a cell is not constant, it can vary depending on sereral factors, such as the age of the organisms, the effect of several drugs, mutations or diseases.
Farming is an agriculture practice, in which crops are harvested, cultivated, and yielded over a period of time. It can be of several types such as contour, terraces, nomadic, and sedentary farming.
<h3>What is Contour Farming?</h3>
Contour farming refers to the cultivation and growing of crops in sequential rows. The rows are level around the hill. Contour farming is found in hills and mountainous farmlands. The farming practice is common in European countries.
<h3>What is Terrace farming?</h3>
Terraces are the farming practice, in which the farmlands are formed by turning hills to form a ridged platform. Terraces are also found in the hilly regions are common in the countries China, Japan, and Southeast Asia.
Thus, contour and terraces farming is the type of agricultural practice done in the hilly and mountainous regions.

Full question:
Several parts of an animal cell are involved in the processes of protein synthesis, packaging, and export. Which of the following correctly places the cell parts in the order in which they are involved?
- nucleus → vacuole → cell membrane
- mitochondria → vacuole → cell membrane
- ribosome → endoplasmic reticulum → Golgi complex → cell membrane
- lysosome → endoplasmic reticulum → Golgi complex → cell membrane
Answer:
ribosome → endoplasmic reticulum → Golgi complex → cell membrane
Explanation
First, the DNA is transcribed into mRNA in the nucleus. The mRNA then moves to the cytoplasm. Here, it encounters the ribosomes.
At the ribosomes. the mRNA is translated into protein. It gets folded in the endoplasmic reticulum and then is transferred to the Golgi complex.
At the Golgi complex, proteins are modified, packaged, and transported to their destination in a series of vesicles, which if it is outside the cell, is the cell membrane.
