alexira [117]

Answer:

C. glucose

Explanation:

Dark reaction takes place outside the thalakoid membrane (stroma and cytoplasm). During dark reactions, energy is released from ATP and NADPH to fix carbon dioxide into <em><u>glucose</u></em>.

Option A and B are not correct because they are produced during light reactions. Likewise, chlorophyll is the part of cell and is not prepared during light or dark reactions at all.

In a membrane, the________of the phospholipids in one monolayer face the________of the phospholipids in the other monolayer.
matrenka [14]

In a membrane, the tail of the phospholipids in one monolayer face the tail of the phospholipids in the other monolayer.

<h3>What is cell membrane?</h3>
  • The cell membrane is a biological membrane that separates and protects the inside of all cells from the outside environment.
  • It is also known as the plasma membrane (PM), cytoplasmic membrane or plasmalemma (extracellular space).
  • The cell membrane consists of a lipid bilayer, which is made up of two layers of phospholipids interwoven with cholesterol (a lipid component) to maintain  proper membrane fluidity  at different temperatures.
  • Furthermore, membranes are composed of membrane proteins, such as those that cannot be separated across the membrane and function as membrane transporters, and peripheral proteins that simply attach to the  outer membrane of the cell and function as membrane transporters. enzymes to help the cell interact with its environment.
  • The integrated glycolipids of the outer lipid layer perform a similar function.

eimsori [14]

Answer:

Height is affected by multiple pairs of genes on different chromosomes.

Explanation:  

The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.

mihalych1998 [28]

Answer: Option D.

Genotype by environment interaction.

Explanation:

Genotype by environment interaction refer to a situation where two different genotypes react differently in an environment. Light skinned humans are at greater risk of skin cancer because they lack melanin which the dark people have and this melanin protect the skin from sun.

All the choices are correct. Differences in the norm of reaction I.e they react different way.

Epistasis is when the effect of a gene suppress the other.

Pleiotrophy is when a gene influence another genes phenotipically. These are all genotype enviromr interaction.
