Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment?
Answer: Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment.
In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.
Answer:
A sewing needle floats when it is placed gently on top of water in a bucket - surface tension
Water molecules ding to plant cell walls - adhesion
A water strider runs across a pond without breaking the surface - surface tension
A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion
Water molecules cling to the side of a beaker - adhesion
Water molecules are attracted to each other - cohesion
Explanation:
The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.
The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.
Hence,
<u>Surface tension</u>
- A sewing needle floats when it is placed gently on top of water in a bucket.
- A water strider runs across a pond without breaking the surface.
<u>Cohesion</u>
- A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface.
- Water molecules are attracted to each other.
<u>Adhesion</u>
- Water molecules ding to plant cell walls
- Water molecules cling to the side of a beaker
<u>Answer</u>: B) centrosome - food storage
<u>Explanation</u>: The organelles known as centrosomes have the purpose of organizing microtubules and thus provide the structure of the cell. They also play a vital part during cell division by pulling the chromatids apart.
Answer:
Explanation:
f(a) = freq of recessive allele
f(A) = freq dominant allele
f(a)^2 = (140/500) = 0,28 -> f(a) = 
= 0,53
f(A) = 1 - f(a) = 0,47
f(aa) = f(a)^2 = 0,28
f(AA) = f(A)^2 = 0,22
f(Aa) = 1- 0,28 - 0,22 = 0,50
