Why is there a higher rate of skin cancer in Australia than in other
parts of the world?
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.

What do hypothesis, theories, and laws have in common ?
Which of the following describes the relationship between genes and
chromosomes?
Chromosomes form into genes during cellular reproduction
Genes are special sequences of nucleic acids found on chromosomes
Every gene an organism has is found on every one of its chromosomes
All of an organism's chromosomes can be found next to its genes in the cell nucleus
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.

Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant
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.

Answer:
maco shark
Explanation:
It is a fast speed-swimming shark that has been called “the peregrine falcon of the sharks” in allusion to the fastest bird in the world. It is considered an animal dangerous to humans because of the speed which can attack and its ability to jump into the fishing boats.

Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

What happens to cause air to be exhaled from the lungs?
A)The rib muscles contract and move upward
B)The chest cavity expands and grows larger
C)The diaphragm relaxes and moves upward
D)The lungs contract and expand
Answer:
The answer is C.
Explanation:
When you breathe out or exhale, your diaphragm relaxes and moves up into your chest cavity. As the space in your chest cavity gets smaller, the air rich in carbon dioxide is forced out of your lungs and windpipe, and then out your nose or mouth.

A solar eclipse happens when --
the sun is directly between Earth and moon
the moon is in Earth's shadow.
the moon is directly between Earth and sun.
the sun blocks out light from Earth.
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.

The pancreas is an organ connected to the digestive tract of humans by a
duct (tube) through which digestive enzymes flow. These enzymes are
important to the digestive system because they
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.

Describe how the lizard population is changing
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.
