Answer:
tongue; middle of the back
Explanation:
- In physiology, the two-point threshold means that there must exist a threshold distance, above which any given subject can differentiate between two different sensations.
- In physics, the two-point threshold is the smallest distance that exists between two points where the person can distinguish those two points as distinct and not one.
- This two-point threshold work by Weber found that the most sensitive area where the threshold distance was the smallest was the tongue and the least sensitive area where the distance was largest was the middle of the back.
He tells her that often scientists do not favor pyramid of biomass because obtaining biomass requires advanced technology
The option C is correct.
Explanation:
The pyramid of biomass is the measure of the amount of biomass of living organisms present at every trophic level or unit area.
The biomass of pyramid is often not preferred by scientist because calculating the biomass is a tedious process.
It requires the heating of dead organism at high temperatures until a dry mass with constant value is obtained.
Although for biomass the size of the organism is taken into account but obtaining biomass requires advance technology.
The rate of biomass increase in organism in growth period is also tedious to measure.

Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).
<u>Function: -</u>
The advancement of the central nervous system, the growth and operation of the reproductive organs, and also the metabolism and blood sugar level, are all regulated by the endocrine system, which is made up of all the various hormones produced by the body from conception and via adulthood and into old age.
Metabolism- The alterations in an organism's or a cell's chemistry. These modifications generate the ingredients and energy that cells and organisms require to develop, procreate, and maintain health. Anabolism and catabolism are components of metabolism.
Hormones- Chemicals called hormones function in the body as messenger molecules. They are created in one area of the body and then go to other areas where they assist regulate how cells and organs function.
