Answer:

The membranes of winter wheat are able to remain fluid when it is extremely cold by Increasing the percentage of unsaturated phospholipids in the membrane

Explanation:

In winter ,cell membrane can freeze but presence of unsaturated fatty acid make it movable because they have Double bond which make them unable to pack tightly due to kinks.

State the unique characteristics of epithelial tissue.​
erica [24]

Answer:  

Characteristics of epithelium tissue

1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)

2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.

3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.

4.Avascular– Epithelium typically lacks its own blood supply.

5.Regeneration– Epithelium cells can regenerate if proper nourished.

6.Absence of nerves (except for a few axons in the deeper layers)

Classification scheme of epithelial tissue:

Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

Kay [80]

Answer:

(A) Sex-linked dominant

(B) Sex-linked recessive

Explanation:

This type of representation is used in pedigrees that express the inheritance of sex-linked characters, that is, those that are inherited through one of the sex chromosomes, which are the X or Y chromosomes.

For this reason it is necessary to represent males and females differently in the scheme

Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons f
denis23 [38]

Answer:

from glycolysis to electron transport.-glycolytic pathway

NADH  and FADH2 are the major electron carrier   from glycolysis through the Kreb Cycle to the electron transport chain.

Note-NADH  alone transports electron  from glycolysis  to the Kreb Cycle. while both   NADH and FADH2  transport electrons   from the kreb'cycle  to the electron transport chain.

from citric ac id cycle to the electron transport chain.

as explained above both NADH and FADH2.

The electrons are  in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial

Note.

Nicotinamide Adenine Di nucleotide Hydrogen(NADH)

Flavin Adenine Dinucleotide Hydrogen(FADH)

Anestetic [448]

Diet and weight-loss companies create the illusion of isolation, as if everyone else has met the ideal beauty standard and that “you aren’t right now, but you can too!” Instead of focusing on the health of the customer, these companies promote their methods of weight-loss before any other. Use skepticism if an advertisement makes claims that seem “too good to be true”, are scientifically unsubstantiated, only provide one perspective/way of thinking, or appear to prioritize sales over health.
