The correct answer is Collenchyma.

The collenchyma cells are lengthened cells with uneven thick cell walls, which are responsible for structure and support. Their thick walls comprises of the compounds pectin and cellulose. These cells are generally found below the epidermis, or the outer layers of cells in leaf veins and in young stems.

These cells provide structural support, mainly in developing leaves and shoots. The strength of the tissue comes from these condensed cell walls and the longitudinal meshing of the cells.

ziro4ka [17]

Answer:

Bb and bb

Explanation:

The most likely genotypes of the parental generation would be Bb and bb.

If Bb and bb are crossed, such that:

                       Bb    x    bb

offspring:     Bb   Bb   bb   bb

Bb = 2/4 = 1/2 = 50%

bb = 2/4 = 1/2 = 50%

hence;

<em>1/2 or 50%% of the offspring would express the dominant condition in the form of Bb and the remaining 1/2 or 50% of the offspring will express the recessive condition in the form of bb.</em>

Which is most likely not a beneficial contribution made by biologists?
Elodia [21]

Answer:

The activity that does not represent a beneficial contribution made by biologists is to improve the durability of non-stick coatings (option C).

Explanation:

The development and improvement of non-stick coatings does not correspond to an activity within the field of biology. Anti-stick coatings, such as Teflon, are products developed through industrial activity.

Biologists' activity is focused on living organisms and their interaction with the surrounding environment. Improving arable soils and food quality, as well as increasing life expectancy are activities that fall within the field of study of biology and its related disciplines.
