The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
A copy of each chromosome In the cell is copied I’m pretty sure
Answer:1. They allow the movement of molecules from one cell to another, enabling communication between cells.
Explanation:the cell wall is a rigid and cellulose containing wall, which surrounds the plasma membrane.
During lignification, small pores appear on the cell wall through which cytoplasmic strands extend.these pores are the plasmodesmata,which provides connections between plant cells
Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
1. The water will leave the cell.
Hypertonic solution
2. There will be no net movement of water.
Isotonic solution
3. The water will leave the cell.
Hypertonic solution
4. The water will enter the cell.
Hypotonic solution
5. I predict that the water will move into the cell because inside the cell, the concentration of water molecules is less than that of outside the cell. According to the process of osmosis, water moves from a region of high water concentration to a region of low water concentration.
Thank you
