Answer:

This question lacks options, the options are:

a) Negative primary production

b) Net primary production

c) Secondary production

d) Negative secondary production

e) Positive primary production

The correct answer is b.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.

Explanation:

Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).

When cells perform photosynthesis, they transform energy from one form to another, what takes place during photosynthesis?
Oxana [17]

During photosynthesis, solar/light energy from the sun is transformed into C6H12O6, or glucose (chemical energy). Photosynthesis is defined as the process by which green plants and some other organisms use sunlight to synthesize foods (glucose) from carbon dioxide (CO2) and water (H20). Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen (O2) and glucose.

Draw the structure of DNA aand write a short note about it.​
artcher [175]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Tom [10]

Answer:

Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.

In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.

In photoperiodism flowering and other developmental processes are regulated in response to the photoperiod, or day length.

Explanation:

there are some key points, hope that helps :)

When you're old enough to vote, will you be influenced by celebrity endorsements ? Why or why not?
liubo4ka [24]

Celebrity endorsers can influence the portion of the public (increasingly small) who otherwise do not have strong candidate preferences and pay so much attention to politics. If the celebrity has huge interest and knowledge of politics so i may get influenced.

<h3></h3><h3>When was celebrity endorsement started in United states?</h3>

Celebrity endorsements in the U.S.  were started in 1920, precisely a hundred years ago, with film stars publicly supporting candidate Warren G. Harding in the presidential election. From then on, many  other celebrities raised their political opinions among their fanbase for electoral candidate.

Celebrities themselves, by making an endorsement may risk losing a share of their audience and inviting public joke and anger.
