A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.

The energy an organism requires to transport materials and eliminate wastes is obtained directly from
nirvana33 [79]

Answer:

ATP

Explanation:

ATP is regarded as 'root of energetics' for living organisms. So, the organisms utilizes ATP to transport material and eliminate wastes from the body. Not only these functions are carried out by ATP but also several others infact all energy requiring processes are carried out ATP. e.g. muscle movements, neurotransmission, heart beats and various chemical reactions in the body all are carried out with the help of ATP.

In animals ATP is produced from the breakdown of glucose in the cellular respiration, glucose is obtained from the diet we take in. In plants ATP is generated from the process of photosynthesis. The source of energy within ATP is phosphate bonds, the breakdown of one phosphate bond while conversion of ATP into ADP produces or releases 30.6 KJ/mole of energy.

A student claims that if the animal producing the spermatozoa has a mutation in a mitochondrial gene, the probability that any o
galina1969 [7]

Answer:

The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring

Explanation:

Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring

In humans the genetic commonality of height and skin tone is that they are both
lubasha [3.4K]

Answer:

In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>

Explanation:

Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.

Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.
