Answer:
b) Apical surface
Explanation:
Apical surface is the portion of an epithelial cell in the stomach that food wouold be in contact with.
Answer: A. The hydrogen bonds cause water to resist a change in temperature.
Explanation:
Heat of vaporization is defined as the amount of heat required to convert 1 mole of liquid to gaseous state.
Water has high heat of vaporization due to the presence of strong hydrogen bonds between hydrogen and a electronegative element oxygen. As the water molecules are strongly bonded to each other, large amount of heat is required to raise the temperature of water.
The molecules will not be able to gain enough kinetic energy and thus temperature changes slowly.
Answer:
D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.
Explanation:
Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.
However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.
Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
Answer:
True
Explanation:
It is correct to say that the deeper in the ground we go, the older things get. This statement is specifically valid in a terrain that has not been disturbed by tectonic activities.
<em>According to the law of superposition of strata "in a sequence of sediment, the oldest layer is usually at the bottom and the youngest is on top provided the area is undisturbed". </em>
Based on this law of superposition of strata, it clearly seen that the deeper we go down in the earth, the older things get.
