The classes of chordata which are warm-blooded are birds and mammals.
Explanation:
Warm-blooded animals are those which can maintain their body temperature at a constant.
These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.
The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.
Warm blooded animals cool themselves with the help of sweat glands.
The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.
These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.
Whale living in water is the fish which is also warm blooded because it is a mammal.
Answer:
1. It seeps in the ground and becomes ground water.
2. It falls back down to earth as Rain, Hail and Snow.
3. Water moves through the living organisms in an ecosystem
4. Transportation is the process that moves things like water from one place to another.
Explanation:
I passed Biology last year in 10th so I recalled my biology stuff.
Answer:
B. It is a nucleic acid
F. It allows parents and their young to have similar characteristics.
Explanation:
The genetic material refers to the molecule which acts as the coding material of the organism as it contains the code of protein and thus controls the basic function of the life.
The genetic material of the organism belongs to a class of molecule called nucleic acid as they are found in the nucleus of the cell. There are two types of nucleic acids called DNA and RNA.
The genetic material gets passed from the parents to the offspring through reproduction therefore the offsprings develop the same character as of their parents.
Thus, the selected options are correct.
Answer:
b. cis test
Explanation:
A test that is used to determine if the mutation associated with a given phenotype is due to mutations in two different genes or due to different alleles of the same gene is called a complementation test.
A complementation test is also called as a cis-trans test.
If the mutations in a complementation test are located on the same position then the genes are termed as being on the cis position otherwise on the trans-position.
A cis test, that is if the genes are located on the same position serves as a control for the complementation test.
