In the lab, you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating

form. If you released that mutant into a small pond shaded by trees, would the mutation spread, and why?
A) Yes, because the xanthophylls prevent the production of reactive oxygen species.
B) No, because the xanthophylls prevent the production of reactive oxygen species.
C) No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.
D) Yes, because the heat released by the xanthophylls would warm up the cells and enhance photosynthesis.
E) No, because mutations never spread in nature

Answer:

No, because xanthophyll dissipates absorbed light as heat, and in low light environments, such dissipation would decrease photosynthesis and therefore growth.

Explanation:

Xanthophyll is one of the accessory pigments present in organisms. Being an accessory pigment, the function of xanthophyll is to dissipate the absorbed visible light. Since it dissipates the visible light, the light cannot be used by Chlorella to drive the light-dependent reactions of photosynthesis.

When a mutant Chlorella is grown in the shady region, the dissipation of light by xanthophyll would further reduce the rate of photosynthesis. This mutation is not an adaptive feature in shady regions where the rate of photosynthesis is already lower due to limited availability of light and therefore, would not be favored by natural selection and would not spread to the future generations.

Answer:

Option B

Explanation:

Complete question -

Following their sixteen-week, closed-ended, grief and loss psychotherapy group with adults as reported by Price et al, which of Yalom's therapeutic factors was most identifiable?

a. recapitulation

b. altruism

c. universality

d. imagery

Solutions -

Out of the eleven therapeutic factors the one that will be easily recognizable will be the one which will involve some kind of action and interaction or any visible signs. Altruism would affect a person positively and help him/her to gain confidence. This confidence will be visible by the person’s action when he/she will help other people in the group to gain value and significance in the same way as he/she has done.  

Hence, option B is correct

How do CAM plants differ from C3 and C4
algol13

Answer:

C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

What letter is the second layer of the rock? ​
Vadim26 [7]

Answer:

Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.

Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.
