TSH level, because if we are testing the levels of TSH with a person who has Hashimoto's disease and one who does not have Hashimoto's disease.
Rock 2- volume=30cm3, mass=60g, and density=2g/cm3
<u>Answer:</u>
The Earth has got its tilted axis and this is the reason for different seasons to be formed. Communities are a set of population found in that particular area and are of two types.
A) Terrestrial (Land)
B) Aquatic (Water).
These communities to flourish need a perfect environment with a perfect season. Hence according to the season formed due to the tilted axis influences the terrestrial community which forms in that particular region and have the ability for the region specific community growth.
The terrestrial community of a tundra or desert or rain forest all depends on the particular season that can be formed due to the position of the earth facing the sun.
Forests would be able to survive a disease better.
<h3><u>
Explanation:</u></h3>
Many studies have taken place for many years to determine what type of ecosystem can best survive diseases effectively. A recent study has concluded that the forests are the viable ecosystem which can survive a disease better then any other ecosystem; followed by grasslands as the second best.
The study states that the chances of forests are better as the ecosystem contains many different species of trees and plants. The mix of several species in an ecosystem helps in surviving climate changes, pests and severe diseases. According to the study, the diversity of different biological species have a better rate of production than an environment which has only one species in it. The biodiversity will help produce the amount of energy that would best suit the needs of population.
Answer:
e. cutin
Explanation:
Plant exhibit many variations to withstand the temperature variations, desiccation and increased UV exposure which are some of the factors associated with land habitat. Cutin is a waxy substance that is found in the outer walls of the epidermal cells of plants. Cuticle in plants serves to make the outer most covering of aerial parts of the leaves and non-woody stem of herbaceous plants. The cuticle is made of cutin.
Cutin serves to protect the plant’s aerial surfaces from excess water loss. It also filters the excess UV light and thereby protects the underlying plant parts. The thickness of the cuticle varies in different plants depending upon the environmental conditions. The leaves of plants adapted to hot, dry climates have thick cuticles. The thickness of the cutin layer also varies in different parts of a plant. For example, the upper epidermis of leaf generally has a thicker cuticle than the shaded and relatively cooler lower epidermis.
