Answer:

In Austrailia there is the highest rate of skin cancer because there is so much sunlight and most austalians have the wrong skin type for thier environment meaning people with pale skin get burnt more easily

Explanation:

Australia has a high rate of skin cancer because there's something different about the sunlight in Australia, and most people in Australia have skin that is easily damaged by light from the sun. Light carries energy that can make materials change. Therefore, Australia has a high rate of skin cancer because the ozone layer is damaged by the energy carried from the UV Light, being absorbed by the ozone and damaging allowing that light to transmit through and damage the genetic material of those individuals with lower levels of melanin.

Answer: The enzymes are important to the digestive system because they help in BREAKING DOWN of food substances that contains fat, carbohydrates and proteins.

Explanation:

In the process of digestion, several substances are secreted into the duodenum which is the first part of the small intestine. The pancreas, through the pancreatic duct, secretes pancreatic juice. This juice contains several digestive enzymes which include:

--> Amylopsin- This helps in the breaking down of starch( CARBOHYDRATES) to maltose.

--> trypsin: this is a protease that helps in the breaking down of PROTEIN into polypeptide.

--> Lipase: This helps in the breaking down of FAT to carboxylic acids and glycerol.

All the above enzymes of the pancreatic juice require an alkaline medium to work in. This is provided by the bile which is secreted in the fall bladder.

Answer:

C. The green allele is recessive to the yellow allele

Explanation:

Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

In eukaryotic cells or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. These events include the duplication of its DNA (DNA replication) and some of its organelles, and subsequently the partitioning of its cytoplasm and other components into two daughter cells in a process called cell division.

In cells with nuclei (eukaryotes, i.e., animal, plant, fungal, and protist cells), the cell cycle is divided into two main stages: interphase and the mitotic (M) phase (including mitosis and cytokinesis). During interphase, the cell grows, accumulating nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the mitotic phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells. To ensure the proper replication of cellular components and division, there are control mechanisms known as cell cycle checkpoints after each of the key steps of the cycle that determine if the cell can progress to the next phase.

In cells without nuclei (prokaryotes, i.e., bacteria and archaea), the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells.

Answer:

Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Answer:

spectroscopy.

Explanation:

The use of light to determine composition of a star is known as spectroscopy. When astronomers look at an object's spectrum, they can find out its composition based on the wavelengths of light. Spectroscopy is the most common method astronomers use for knowing the composition of stars, planets, and other objects so we can conclude that spectroscopy is the method which is used to determine the composition of stars.

Answer:

Genes are special sequences of nucleic acids found on chromosomes.

Explanation:

A single DNA molecule is a chromosome. A gene is a certain chromosome region of DNA.

All cells of the body are genetically the same, but cells are different from others because specific gene sets are expressed. Different cells, therefore express different genes, which enable them to perform a specific function.

The deoxyribonucleic (DNA) genes are segments that contain a code for a certain protein that works in one or several cell types in the body. Chromosomes are cellular structures that contain the genes of a person. Genes that are in the cellular nucleus are contained in chromosomes.
