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.
Answer: 14
Explanation:
(-4) + (-4) + 6+6+5 + 5
Recall that BODMAS rule must be obeyed
Address bracket first, and note that plus sign multiplied by minus sign becomes minus
so, (-4 - 4) + 6+6+5 + 5
(-8) + 6+6+5 + 5
= (-8) + 6+6+5 + 5
= (-8) + 22
= 14
Thus, the answer is 14
Answer:
P(purple, short) = 3/16
Explanation:
Purple flowers require genotypes Pp, pP or PP
Short pollen grains require genotype ll
The genotypes are
PPll (1/16), Ppll (1/16), pPll (1/16) for a total of 3/16
Normally it is seen that objects with more mass accelerates during their free fall than objects having smaller mass. The frictional force of air also known as the drag force get negated by the massive object and so the object gets acceleration during the free fall. If the mass of the object is small, then the frictional force or the drag will slow the object during free fall. In case of vaccum the mass of the object does not matter as there is no drag or frictional force working against it. The objects with greater or smaller mass will then free fall with the same speed in the vaccum.
I belive they studied rocks because that is what geological stands for.However they also studied glaciers and ice caps for seeds that contained pollen. The prehistoric 4imes often help us understand out history.
