Answer:

Option C . Flip-flops are very rare for phospholipids.

Explanation:

Flip-flop means that movement of phospholipds upside down. This phenomenon occur in cell membrane but very rarely. I have attached a picture for you to under stand how flip-flopping occurred.

<h2>Transforming Bacteria</h2>

Explanation:

  • Archaea and bacteria are different in the qualities of the cell wall and in the lipid composition of their cell membranes
  • <em>Bacterial cell dividers contain peptidoglycan</em>
  • Archaean cell wall don't have peptidoglycan, yet they may have <em>, polysaccharides, glycoproteins, or protein-based cell dividers </em>
  • Bacterial cell walls are made of peptidoglycan (likewise called murein), which is produced using polysaccharide chains cross-connected by abnormal peptides containing D-amino acids

Pea plant clones are given different amounts of water for a three week period.
pentagon [3]

Answer:

independent variable: the different amount of water

Explanation:

The independent variable would be the <u>different amount of water supplied to the pea plant clones.</u>

<em>The independent variable is the variable inputted by the researcher during an experiment whose value directly affects the dependent variable. It is the variable that is manipulated during experiments in order to see the kind of effects they produce on another variable - the dependent variable.</em>

In this case, <u>the amount of water supplied to each pea plant would directly affect the height of the pea plants.</u> Hence, the amount of water supplied to the pea plants is the independent variable while the height of the plants is the dependent variable.

What is the primary product of light independent reactions
SOVA2 [1]

The primary products of the light independent reactions  (after one turn of the cycle) are:

a)  two G3P molecules

b)  three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions.  Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of  the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there  remains only one carbon for the next turn of the cycle.

One  molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.

Plant cells __________.
quester [9]

Answer: Option B) have mitochondria and chloroplasts.

Plant cells have mitochondria and chloroplasts.

Explanation:

Unlike animal cells, plants cells possess mitochondria and chloroplasts. Mitochondria serves as site for respiration giving off oxygen as by-product while chloroplasts are site of photosynthesis, where sugar molecules are formed from simple inorganic molecules like atmospheric carbon dioxide, water and sunlight trapped by chlorophyll.
