Answer and Explanation:
Mutation:
It is the sudden variation that occurs in the sequence of our DNA either due to factors related to environment or mistakenly. These are inheritable changes in our genes.
Effects:
a. It results in the ability of an organism to adapt to the environmental variations.
b. It can also cause disorders and diseases in an organism.
c. It results in the evolution of organisms.
d. It also results in the variation in an organisms' phenotype.
d. It helps to carry out scientific research.
Patterns of Inheritance:
The inheritance in mutation only occurs when it is in germ cells which leads to the production of gametes and this mutation is known as germ line mutation.
Data analysis:
As only few cells are effected mostly in mutation it can not be detected.
Answer:
If our upright bones were not strong and sturdy then we will be very weak to do work and to do small work also our body didn't support us and we will be always afraid of our body
Majority of animals on earth are classified as invertebrates. They are the cold-blooded animal that do not have a backbone. They can be found on land or water. 98% are invertebrates while 2% are vertebrates.
Mammals are vertebrates and humans are the most common mammals on Earth. Radial symmetric does not possess left and right sides. An example is a jellyfish.
Answer - Option 4 - Invertebrate
Answer:
There are many ways.
Explanation:
Humans have a combined respiratory and circulatory system, whereas insects do not. In humans, the air is brought in through the mouth/nose, through the windpipe, and into the lungs, the oxygen is absorbed into the bloodstream where it can be transported to muscles and organs. However, insects take in air through tiny holes in their thorax and abdomen. These are called spiracles. The oxygen is stored in many dorsal air sacs to be used. Then carbon dioxide is expelled through the spiracles.
