Answer: The correct answers are 1) Endocytosis and 2) Receptors are specific for the cells.

White blood cells are specialized cells of the immune system. They play important role in protecting body from foreign agents like bacteria . For this, they recognize the bacteria and forms a covering around it, pinching off the vacuole. By this, the cell performs a process called as Endocytosis ( specifically phogocytosis).

The receptors present on the white blood cells are quite specific. Due to this, they recognize specific foreign particles. For example B- cells produce antibodies which bind to specific antigens ( foreign protein) and therefore mount specific immune response. In other words, specific foreign particles are recognized by specific white blood cell. This indicates that the receptors on these cells are specific.

Thus, the correct answer is 1) Endocytosis and 2)  Receptors are specific for the cells.

Answer:

The correct answers are endocytosis and the receptors are specific for the cells.

Explanation:

The white blood cells are the unique cells of the immune system. They perform an essential function of safeguarding the body from foreign agents like bacteria. In order to do so, they identify the bacteria and produces an envelope around it, pinching off the vacuole. With the help of this, the cell performs a procedure known as endocytosis.  

On the white blood cells, the receptors found are very unique, as because of them they identify the particular foreign particles, like B cells generate antibodies that combines with the particular antigens, and thus, impart specific immune response. Or it can be said, that specific foreign component is identified by the unique white blood cell, which shows that the receptors on these cells are unique.

Fruit flies have a diploid number of 8, and honeybees have a diploid number of 32. In which case will crossing over have greater
Yanka [14]

Answer:

            The correct option is A.

Explanation:

              As we know that genetic variation that result from crossing over depend on the number of genes and their alleles. When there are more genes in genome the chances of polymorphic loci will increase, which will result into more genetic variation during crossing over.

Forexample:

                    Drosophila melanogaster is a common fruit fly having diploid number of 8 chromosome composed of 122,653,977 base pairs, and about ~17,000 genes.  Honey bees have diploid number of 32 chromosomes composed of approximately 2360000 base pairs, and 10,000 genes.    

Conclusion:

                      As fruit fly genome contain more genes and polymorphic loci, so genetic variation is more likely to be greater in fruit fly.

Daniel is studying feeding relationships in a neighborhood pond. He observes several organisms that feed on one another, and he
vichka [17]

So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.

The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.

Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.

If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.

So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.
