Scientists recently discovered a species of bacteria that’s capable of photosynthesis, but it’s anaerobic and doesn’t produce or use oxygen for respiration. Which process will be absent in this organism?
A.
Calvin cycle
B.
electron transport system
C.
glycolysis
D.
Krebs cycle

Answers

Answer 1

Explanation:

The answer is D. Krebs cycle. the Krebs cycle only occurs when oxygen is present, and so it would seem to be the same for the electron transport system... although, in anaerobic bacteria, it is still used as a respiratory electron transport chain called physolmere.

Answer 2

Answer:

Krebs cycle

Explanation:

all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks​

Answers

Answer:

Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.

As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

How does a rain shadow affect the weather?

Answers

Answer:

Energy

Explanation:

Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

Why is it important that the seedling’s true leaves grow quickly?HURRY IM BEING TIMED

to help disperse seeds to areas where they can grow
to shield the seedling from too much water or rain
to protect the seedling from receiving too much sunlight
to make food for the seedling’s continued growth

Answers

Answer:

The correct answer is - to make food for the seedling’s continued growth.

Explanation:

The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.

Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.
