If chemical bonds did not exist, or were so strong that they never broke apart, there would be no movement of ______, which is r

ch4aika [34]

Answer: Energy

Explanation:

If there is no chemical bonds in the substance or the bonds in the substances are so strong so there would be no energy released.

This is because there is a need of energy when any bond is formed and energy is released when bonds are broken down.

Energy is stored in the bonds which is released when bonds are broken down.

There would be no energy available for various processes and no movement of energy will take place.

6) If a mutation happens in a cancer-causing gene to change the subsequent protein's function,

Aneli [31]

Explanation:

B) False

Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer

Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.

Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

somatic: these only occur within certain cells, and arise from environmental factors such as UV light
hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Snapdragons are a type of flower. When red snapdragons are crossed with white snapdragons the resulting flowers are all pink. A

Akimi4 [234]

There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.

The genotypes and phenotypes that we will employ to address this issue are as follows:

RR - Red

RW - Pink

WW - White

They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross

RW x RW

The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)

This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.
