Answer:
THE CHANGE LIKELY 10 AND 30
Explanation:
Changes to the classification system have meant that the classification of some species of organisms has changed too. The system had to be changed to incorporate this new group or organisms.

<em>B. Has the same allele on both chromosomes in a chromosome pair. </em>
<u>Here is why:</u>
Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.
There can be two types of homozygous alleles.
~
<em>Homozygous Dominant</em>: BB
<em>Homozygous Recessive</em>: bb
<u>Notice in both of these they were the same alleles.</u>
~
<em>Heterozygous</em>: Bb
<u>Notice how both are different alleles.</u>

Below I have attached a diagram of a Punnett square I have made.
On the left is a homozygous recessive allele pair.
On the top is a heterozygous allele pair.
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.
They show all or part of earth.
<u>Explanation:</u>
Maps are the pictorial representation of earth. The people who draw maps are called cartographers and the maps are represented usually as 2D images. A map of earth gives an idea about the differences in sizes of the countries of the world and various geographical features.
A map usually uses a scale which gives an idea about the relationship between distances on the map and actual distance on earth. Scales can be of different types like verbal scale, representative fraction, graphic scale etc.
