Answer:

The given statement is false.

Explanation:

The mammals can be differentiated into three main groups on the basis of the development of their babies. These three groups are marsupials, monotremes, and placental mammals, which is the largest group. The monotremes refer to the mammals, which lay eggs. The marsupials refer to the mammals, which give birth to young ones that are not developed completely. While in a placental mammal, the development takes place within the body of a mother until and unless its systems of the body start to work on their own.

STALIN [3.7K]

Answer:

Option A

Explanation:

As we all know, energy can never be created . Also it can never be destroyed. However, it can only be changed from one form to the other. In this case, when a pool ball is striked by a stick, the kinetic energy of stick is transferred to the ball along with release of sound. Sound is just another form of energy.  

Now, when this ball strikes other balls, the same process is repeated i.e the ball strikes another ball and passes on its kinetic energy along with release of sound energy. Every time sound is released, the amount of kinetic energy transferring from one body to other reduces.  

Option A is correct

Red-green color blindness is a recessively inherited disorder that affects 7% of the male population but only 0.4% of the female
Vesnalui [34]

Answer:

Men express all the X-linked genes present in their genome.

Explanation:

Human males have one copy of X and one copy of Y chromosomes. They express all the alleles present on their X chromosome irrespective of its dominant or recessive nature. This occurs because males do not have a second copy of the X chromosome to carry another allele for the same gene. Color blindness is caused by a recessive allele present on the X chromosome. Males carrying one copy of this allele exhibit the disease while females need two copies of the allele of color blindness to express the disease. Therefore, males are more frequently affected by this disease.
