Answer: 3. in the icecaps. 2. temperature. 1. the second one
Explanation:
As you stated before, cellulose is found throughout the cell walls of plant cells. Cellulose makes cell walls rigid, so that would indicate that cellulose is a carbohydrate.
The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
Answer:The best explanation is;
The materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials
Explanation: A protoplanet is an embryo formed in a protoplanetary disc which has passed through a melting phase that enables the formation layered interior
In protoplanets the effects of partial melting of the components due to heating produced by radioactive decay and pressures from forces of gravity there is segregation of the melt and igneous composition such that the heavier melted metal can sink and be over laid by the lighter igneous rocks
Therefore, the best explanation is that the materials undergo decay when they collide, which results in the heating and subsequent melting and segregation by the sinking of the heavier melted materials and rising of the lighter igneous materials.
