Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds.

mrs_skeptik [129]

Answer:

d. None of these  

Explanation:

Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>

An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.

These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.

It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.

IgorC [24]

Answer:

Its is a lysosomal storage disease!

Explanation:

<u>Hurler syndrome:-</u> is also known as mucopolysaccharidosis-I .

It Is due to the mutation on chromosome 4 .

There is a lack of of enzyme called alpha-L-iduronidase.This enzyme is present in lysosomes

It causes accumulation of mucopolysaccharides because of the absent of the enzyme in the lysosome

<u>Hunter syndrome:- </u>is also known as mucopolysaccharidosis-II

It occurs due to mutation in iduronate-2-sulfatase (IDS) gene.It is an X-linked disease
