It's C. A blastocyst implants into the uterine wall.
c. hydrogen
b. energy
d. glucose
The correct answer is b - energy
Chlorophyll is a green pigment that has light absorbing ability. Light from the sun contains energy in the form of photons.
The photons are trapped by chlorophyll and are used to provide power to split water molecules in the leaf in the process of photosynthesis.
Because chlorophyll is a pigment that absorbs light, it is called a photoreceptor. By absorbing light energy, chlorophyll is vital in the photosynthesis and without it, green plants would not be able to get power to run photosynthesis.
cells! A newly-made cell will grow, but once it reaches a certain size it will divide to form two
new cells rather than growing bigger. Why is this? Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions? Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? In this lab, we will investigate this question using model cells.
Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

A Septum separates the heart's left and right sides to keep oxygenated and deoxygenated blood from mixing.
The septum of the heart is the wall that divides the left side of the heart to the right side.
The septum that divides the upper chambers of the heart is called the atrial septum.
The ventricular septum divides the lower chambers of the heart.
Thus., the correct option is b.) It separates the heart's left and right sides to keep oxygenated and deoxygenated blood from mixing.
