Answer:
This question lacks options, the options are:
A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.
B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength
C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat
D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch
The answer is:
As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.
Explanation:
Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.
Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.
These proteins allow substances to enter that wouldn't be able to otherwise. Only small hydrophobic substances can enter cells. However, these proteins aid crucial substsances in entering the cell.<span />
Answer:
Thymosin
Explanation:
Thymosin is the term used to refer to a set of thymus polypeptide hormones that influence the maturation of T lymphocytes intended to play an active role in cell mediated immunity. Thymosin may serve as an immunotransmitter by modulating the hypothalamic-pituitary-adrenal and gonadal axes. It also helps to counteract the harmful effects of cortisol.
<u>Answer:</u> C. A plant absorbing carbon dioxide during photosynthesis
<em>A plant absorbing carbon dioxide during photosynthesis can be considered as assimilation in the carbon cycle.
</em>
<u>Explanation:</u>
<em>The process of carbon fixation is called assimilation in carbon cycle. In the atmosphere carbon occurs in the form of carbon dioxide. </em>
By the process of carbon fixation this carbon dioxide is converted into carbon compounds and these act as source of energy in an ecosystem.
Photosynthesis is an example of carbon fixation process. Other processes like chemo-synthesis also fix carbon. <em>Majority of carbon fixation takes place in marine environments. </em>
<span>If star A is farther from Earth than star B, but both stars have the same absolute magnitude, the option which is true about their apparent magnitude is that star B has the greater apparent magnitude.
Apparent magnitude refers to the magnitude of an object in space as it is actually measured from the earth, whereas absolute magnitude refers to the star's brightness.
