Independent variable in a investigation is the factor you control and change (e.g. in plant biology it could be light intensity, a concentration level of substances in added water or soil) that influence the dependent variable (in plant biology this would be the rate of photosynthesis).
There must be a number of groups to prove the influence of the independent variable on the dependent variable and trials to increase credibility of the results. Remember to include a control group where independent variable is not changed. (e.g. in measurement of light intensity on the rate of photosynthesis there must be a control where the light intensity is not manipulated to present the regular rate).

What happens when light energy excites electrons in photosystem II?
Vlada [557]

Answer:

C. Electrons are released into the electron transport system.

Explanation:

Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.

<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.

Hence, the correct option is C.

The  offspring  that  can be  described  by  the genotype  is  Gg   while  for the  phenotype  is  green  pod color

  The cross between  GG  and  gg  give   a  heterozygous  offspring  that Gg  offspring.    The  offspring  are  have a green  pod  color  since  the   green  pod  color  is dominant over  yellow  pod  color    and  therefore  the offspring  have  a  green  pod color. The  cross  is  as the  punnet square  below.

Paneth cells ________. A. are absorptive cells in the small intestine B. secrete enzymes that kill bacteria C. are located next
dedylja [7]

Answer:  B. secrete enzymes that kill bacteria

Explanation:

Paneth cells, so-called because they were first described by Dr. Josef Paneth in 1888, are pyramidal cells, with the nucleus in the basal position, and with large granules in the apical position. Its first isolated specific product was the lysozyme, a bactericidal substance, by Alexander Flemming. These cells play an important role in innate immunity in the small intestine, producing a wide diversity of antimicrobial peptides and enzymes such as lysozyme itself, cryptidines, defensins and a lectin with bactericidal properties.
