Answer:

Both provide organisms with usable energy.

Explanation:

Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.

During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.

  • Both processes furnishes an organism with energy in the end.
  • Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy.
  • This energy is used by both plants and animals for their living activities.

Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

A frog with a mass of 0.29kg hops up in the air. At the highest point in the hop, the frog has a gravitational potential energy
PtichkaEL [24]

Answer:

0.27m

Explanation:

To get the energy

Potential energy= Mgh

M is Mass

G is acceleration due to gravity

H is height..

M= 0.29kg, h= ?

P=0.759. g=9.8m/s

Therefore,

0.759=0.29×9.8×h

H= 0.759÷2.842

H= 0.27m

How can humans reduce<br> the impact of a storm surge?
Xelga [282]

Explanation:

reducing the impact Global climate change may result in increased storm surge flooding in some areas, through intensification of the cyclones driving the storm surges and as a result of sea level rise. Mangroves can reduce storm surge water levels by slowing the flow of water and reducing surface waves.

What is the determining factor for the transcription of structural genes of the trp operon?
padilas [110]

The right answer is 3. the availability of tryptophan in the environment

The TRP operon regulation depends on the availability of the tryptophan molecule (it depends if the cell need tryptophan or already has it).

There are two modes of regulation of the trp operon: Suppression and Mitigation

*Repression

The synthesis of operon mRNA is controlled by a repressor that blocks transcription when bound by tryptophan, which acts as a co-repressor.

The repressor, a 108 aa homodimer (ie 2 apo-repressor), has helix-turn-helix domains that interact with inverted repeats at the major groove of the operator, thus allowing its fixation.

In the absence of trp, the repressor is inactive and does not attach to the operator. The RNA polymerase can bind to the promoter and transcribe the trp E, D, C, B, A structural genes.

In the presence of trp, the repressor changes conformation and becomes active, so it binds to the operator, preventing RNA polymerase from accessing the promoter so transcription will not occur.

* The Attenuation

This is a premature termination of transcription that is a function of Trp concentration. It takes place at a late moment of transcription while regulation by repression is done during the initiation.

1st Case: Low Trp Rate, Continuous Transcription, → Formation of the Anti-attenuator in the absence of trp, and therefore the synthesis of tryptophan is continued.

2nd case: High rate of trp, stop transcription, → Formation of the attenuator in the presence of trp. This one will attenuate the synthesis of tryptophan.
