Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves

jarptica [38.1K]

Answer:

The correct option is;

Water absorbing energy in large amounts to increase energy by a degree of temperature

Explanation:

The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls

Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose

The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds

The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.

Explain Ionic and covalent bonding

Lesechka [4]

Covalent bond is when two atoms share one or more pairs of electrons, an example of this could be H20 or C02.

ionic bonds are when one or more electrons from am atom are removed and attached to another, which can result in positive or negative ions which attract each other, an example of this could be table salt.

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.

How do life forms change over time

DIA [1.3K]

Look up Dawrin's theory of evolution. Basically, fossil records show how life forms change over time through evolution.
