The correct answer is A. Apical meristem
Explanation:
In plants, the primary growth refers to the type of growth that increases the length of the stem or toots in opposition to the secondary growth in which the stem thickens and that occurs as the result of the vascular cambium. However, in the case of primary growth, this can be explained mainly due to the action of apical meristem that is a type of tissue located in the tips of roots and the stem and therefore the type of tissue in which the growth takes place mainly through cell division. Considering this, it can be concluded primary growth is due to the action of the apical meristem.
Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.
As the question is incomplete and there are no statements available based on which the question can be answered. But based on the knowledge it can be answered.
Answer:
Most of the corals contains photosynthetic algae which are known as zooxanthllae which lives in the tissues of the corals. Algae and corals have mutualistic relationship.
The corals provide algae space to live and algae provides coral food such as glucose and glycerols to them which are considered as products of photosynthesis.
If the producers are hampered by the catastrophic event then the main source of the food will be hampered. There will be less or no food source for the corals which covers a large area in the marine ecosystem.
There are chances that there will be more load on the other photosynthetic organism in water as there will be more population dependent on them for food.
Hence, if there is a loss of habitat for these protist other levels of food chain will be affected due to inter connection.
Answer:
The greenhouse effect is caused by the atmospheric accumulation of gases such as carbon dioxide and methane, which contain some of the heat emitted from Earth's surface. This radiation, unlike visible light, tends to be absorbed by the greenhouse gases in the atmosphere, raising its temperature.
Explanation:
Just search it up- you can look at that and re-write it if you want
Answer:
The force that holds the gases in the sun. The force that causes a ball you throw in the air to come down again. The force that causes a car to coast downhill even when you aren't stepping on the gas. The force that causes a glass you drop to fall to the floor.
