How is the process of carbon fixation in CAM plants different from the process in C3 and C4 plants? a. CAM plants require a larg

er exchange of gases in the atmosphere than C3 and C4 plants. b. CAM plants are better adapted for moist, low light areas than C3 and C4 plants. c. CAM plants conserve water by allowing transpiration to occur at night rather than the day like it does with C3 and C4 plants. d. All of the above

Answer:

The correct answer would be option C.

Plants evolved different methods to prevent or reduce the effects of photorespiration.

The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.

The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.

In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.

The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.

Explain why studying microorganisms such as bacteria can help scientists understand how evolution works.
Nezavi [6.7K]

Answer: New research shows that colonies of Escherichia coli can demonstrate a form of learning.

Explanation: Bacterial colonies can evolve the ability to anticipate changes in their immediate environment, say researchers led by Saeed Tavazoie at Princeton University in New Jersey. Other types of bacteria could too. This skill could give them the edge over other bacteria that merely adapt themselves to current conditions.

An epithelium with a single layer of tall cells would be classified as which type of epithelium?
lions [1.4K]

The epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.

Epithelium is one of the major types of body tissue that line the outer surfaces of organs and blood vessels throughout the body.

The epithelium performs the following functions that include:

  • protection,
  • secretion,
  • secretion, absorption,
  • excretion,
  • filtration,
  • diffusion, and
  • sensory reception.

There are also different types of epithelium found in different parts of the body. A typical example is the simple cuboidal epithelium.

Simple cuboidal epithelium are single layered epithelium that are as tall as they are wide (cuboidal in shape).

They are found lining areas that are active in secretion and absorption.

Therefore, the epithelium with a single layer of tall cells is classified as simple cuboidal epithelium.

What is agricultural monoculture and why is that bad for crops?
Katarina [22]
<h2>EXPLANATION:</h2>

<h3>Modern monoculture requires vast amounts of rain for irrigating crops as moisture retention is limited in the soil. A lack of topsoil also increases rain runoff. To achieve this vast amount of extra water it means draining from lakes, rivers, and reservoirs, which is exhausting natural resources and aquatic ecosystems.</h3>
