Answer:

tumor suppressor gene

Explanation:

A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?
Scorpion4ik [409]

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

BabaBlast [244]

Answer:

50

Explanation:

A punnet square can be described as a diagram which illustrates all the possible outcomes of a cross. It is used to tell about the percentage chances for the kinds of genes being transferred to offsprings.

In order to check the percentage of red flowers we can draw a punnet square. As red flower is a recessive trait and pink flower a heterozygous trait,the punnet square shows that a cross between them will give 50 percent red flowers and 50 percent pink flowers.

According to MacArthur and Wilson's hypothesis of island biogeography, species immigration and extinction rates on a particular
lozanna [386]

Answer:

The correct answer will be- Option-A

Explanation:

The Theory of Island Biogeography was proposed by the MacArthur and Wilson's in 1967 which proposed that the number of species-immigration and extinction rates are determined by the size of the island and distance of the island from the mainland.  

The suggestions made by them are:

1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.

2. Smaller island shows a high rate of species extinction as compared to the larger island.

Thus, option-A is the correct answer.
