Answer:

The correct answer will be option-C

Explanation:

Haemophilia is an X-linked recessive disease which expresses its effect only when both the alleles carry the recessive gene that in homozygous condition.

In the given question, according to the standardized rules and symbols to study the pedigree of disease suggests that the affected person should be represented by the filled male and female boxes with dark color.  

So, by looking at the pedigree, one can conclude that John is not affected by the disease and does not carry the alleles for the disease.

Thus, Option-C is the correct answer.

Answer:

The correct answer is C. does not have hemophilia

Explanation:

In the given pedigree John has an XH chromosome, which means that he has the dominant chromosome. As males have one X, they can either be affected or unaffected. So, in this case John could not be carrier. Also, the Dominant chromosome is fully functional and does not show the characters of the disease, so, John would be free of hemophilia.

How are the lytic and lysogenic cycles similar and different in terms of process and infection?
ELEN [110]

Answer:

<h2>Lytic cycle: involve that there is rupture( lysis) of the host cell and release many copies of virus. </h2><h2>Lysogenic cycle:  involve the insertion of the nucleic acid of a bacteriophage into host genome, known as prophage. </h2>

Explanation:

There are many  similarities and differences between lysogenic and lytic cycles that;

1. Lysogenic cycle of bacteriophage :

i)  in lysogenic cycle:  bacteriophage insert its DNA with that of a host, known as prophage and it replicates with host.

2. Lytic cycle of bacteriophage:

i) lytic cycle is that it results in many copies of the virus very quickly and the cell is ruptured and many copies of virus are released.

4. Similarity is that in both cycles bacteriophase inter into the host and use their machinery.

The blastocoel and blastopore are both found in the blastula stage of development.
Andreyy89

Answer:

False

Explanation:

Cleavage in zygote forms a hollow ball of cells known as a blastula. The blastocoel refers to the fluid-filled cavity present in the blastula stage of early embryonic development.

Blastula undergoes gastrulation during which some of the cells exhibit inward movement and form a sac. The blastopore refers to the opening of this sac present in the gastrula stage of embryonic development.

Blastopore of gastrula develops into the mouth in protostomes and becomes anus in deuterostomes.

Assessing biodiversity:
Helen [10]

Answer:

The correct answer will be option-A

Explanation:

Biodiversity refers to the diversity of the biological entities present in an ecosystem. Biodiversity has a wide spectrum which not only includes the number of the diversity of the organism but also the interaction between them.

The biodiversity is assessed to study the changes that are taking place in an ecosystem, to study the causes and how the changes affect the human well being.

The assessment decisions ignore the personal interests and the biasness as the aim of the approach is not fulfil the personal needs but to maintain sustainable management of the ecosystem.

Thus, option-A is the correct answer.
