D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
Answer:
A. Phytoplankton
Explanation:
They as producers contribute the most. Others do too, but not as much.
Answer:
Answer in Explanation
Explanation:
Before we proceed to explain the relation between the two, we need to understand what these terms are.
Acidification of the ocean simply refers to an increase in the acidic content of the ocean due to increased level of dissolved carbon iv oxide.
When we talk of climate change, we are talking about the overall and continual change of the atmospheric conditions of the Earth.
The reason why there is a climate change increase is because the atmosphere which is supposed to serve as a sink for green house gases is not serving this purpose and as such there is a retention of the green house gases such as carbon iv oxide within the sun-atmospheric level on the earth.
These green house gases such as carbon iv oxide which does not find a way out of the earth’s atmosphere will be retained in bodies within the earth crust serving as a sink for them. An example of this sink is the ocean which thus takes in the carbon iv oxide which when dissolved increases the acidic content of the ocean causing acidification
<h2>c) is the correct option </h2>
Explanation:
- All vesicles which are involved in protein targeting are protein coated that assemble on cytosolic surface
- Clathrin coated vesicles are those types of vesicles which are involved in both retrograde as well as anterograde transportation
- Retrograde transportation is the one where transportation occurs from Golgi to Endoplasmic Reticulum whereas Anterograde transportation is the one which involves transportation from Endoplasmic Reticulum to Golgi
- Vesicles originated from either Trans Golgi Network or plasma membrane and fuse with either lysosomes or plasma membrane
- Proteins transportation occurs from Trans Golgi Network to lysosomes, Trans Golgi Network plasma membrane and from plasma membrane to endosome
Answer:
Because each daughter cell must contain an equal and correct amount of genetic material (DNA)
Explanation:
Mitosis and Meiosis are both types of divisions that cells undergo. They both involve the production of new daughter cells. Each cell contains the information needed by it for its life processes. This information is stored in the genetic material known as DNA.
However, when a cell divides during mitosis and meiosis, two and four new daughter cells results respectively. These daughter cells need to contain the genetic material (DNA) that stores the genetic information needed for their survival. The cell ensures that each daughter cell that will result from the process of mitosis and meiosis contains this genetic material by undergoing a process called DNA REPLICATION before the start of the divisions (mitosis and meiosis).
DNA replication is the process of doubling or duplicating the information in the DNA. Hence, at the end of the replication process, the cell contains two copies of the genetic material (DNA) which separates into the daughter cells equally during cell division (mitosis and meiosis).
Protein synthesis does not need DNA replication as it involves using the information in the genetic material (DNA) to synthesize useful products (protein).
