Answer:

The correct answer is "Red shift"

Explanation:

Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.

Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.

The air temperature rises in the stratosphere because of:

Anna71 [15]

Answer:

E. ozone layer.

Explanation:

The pattern of temperature increase with height in the stratosphere is the result of solar heating as ultraviolet radiation in the wavelength range of 0.200 to 0.242 micrometre dissociates diatomic oxygen (O2).

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life pr

lesya [120]

Answer:

Two processes were described in this question, hence, the location of the two processes are as follows:

synthesize energy-rich organic molecules- CHLOROPLAST

Break them down to extract energy- MITOCHONDRIA

Explanation:

Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.

However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.

Enzymes lower the activation energy for a chemical reaction to proceed.

seropon [69]

Answer:

The statement is true since one of the main functions of the enzyme is to lower the activation energy so that a chemical reaction to proceed.

Explanation:

Enzymes are specialized protein molecules that contribute to faster chemical reactions. One of the functional characteristics of an enzyme is that it reduces the activation energy for a reaction to occur.

Activation energy is the amount of net energy required for a reaction to occur. By lowering the activation energy, a reaction occurs faster, which is achieved with a biocatalyst such as enzyme.
