How do chloroplasts get energy from sunlight?

Biology

erastova [34]3 years ago
5 0

Plants are special in the manner that they possess the tendency to generate their own food with the help of energy they get from the sun. A component in the plants known as chloroplasts receives energy from the sunlight with the help of molecule chlorophyll. Chlorophyll along with certain other accessory pigments possesses the tendency to absorb a specific kind of wavelength of energy from the sun.

The molecule chlorophyll is located within the thylakoid. It has the tendency to absorb energy from the Sun, and it is also a specific pigment, which provides plants their green color.

Thus, the correct answer is chlorophyll and other pigments absorb energy from certain wavelengths of visible light.

<h2>Answer </h2>

Lactic acid fermentation ocurrs in muscle cells when oxygen is in low supply

<u>Explanation</u>

The lactic acid fermentation in the muscles cell occurs when muscles work faster and it occurs due to the lack of supply of oxygen in the cell. The lactic acid fermentation is a type of aerobic respiration. The lactic acid formation is due to excessive exercise by individuals and oxygen which is essential for living, is less in the muscle which causes the feeling of burning in the muscles.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What i
zavuch27 [327]

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

p^{2} + 2pq + q^{2} =1

p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\

Thus, the individuals homozygous for the allele can be calculated by q^{2} = (0.7)^{2} \\= 0.49

Is the space between the bottom of the objective lens and the surface of the slide.
Svetlanka [38]

WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.

The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.

The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the  working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane

If the bacterium staphylococcus aureus experiences a cost for maintaining one or more antibiotic-resistance genes, then what sho
djyliett [7]
The bacteria must be outcompeted and substituted by bacteria that have gone this genetic factor. In addition, antibiotic resistance is a natural phenomenon.  Once an antibiotic is used, bacteria that can fight that antibiotic have a greater chance of existence than those that are vulnerable. The vulnerable bacteria are exterminated or inhibited by an antibiotic, subsequent to a selective weight for the existence of resilient tensions of bacteria. Around opposition happens without human deed as bacteria can yield and use antibiotics in contradiction of other microorganisms, prominent to a low-level of the natural assortment of opposition to antibiotics. Though, the presently advanced points of antibiotic resilient bacteria are credited to the abuse and abuse of antibiotics.
