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 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.

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.

John is in his forties and his blood pressure reading shows consistently 160/100 mm of Hg. Name the disease. Mention any four reasons for such a condition?
Answer:
Stage 2 hypertension
Explanation:
Hypertension is a body circulatory system condition whereby the pressure of the blood vessels are raised persistently. The heart pumps blood to the different organs of the body through the blood vessels, each time it beats
The normal blood pressure in the vessel = 90/60 mmHg to 120/80 mmHg
The blood pressure of a prehypertension person or person at risk of having hypertension = 120-139/80-89 mmHg
The blood pressure at Stage 1 hypertension = 140/90-99 mmHg
The blood pressure at Stage 2 hypertension = 160/100 mmHg.
Help me plsssss!!!!!
Answer:
b
Explanation:
Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes. The differences in permeability between artificial lipid bilayers and cell membranes arise from variations in phospholipid content. Transporters are similar to channels, except that they are larger, allowing folded proteins as well as smaller organic molecules to pass through them. Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Answer:
CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.
Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Explanation:
CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.
Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.

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.

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.

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.

Your senior thesis project involves working out the taxonomy of Florida skinks. To accomplish this you examine skink specimens for morphological differences compare nucleotide and amino acid sequences and observe the skinks reproductive behavior and habitat types. Once you have completed the taxonomy and written the thesis you give it to your professor for comments. She tells you that you did a great job and should try to get your work published. However she suggests you indicate in the introduction what species concepts you used to make your classifications. What statement would you add
Answer:
I will add the following statement:
Taxonomic determinations were made based on the general lineage species concept.
Explanation:
Taxonomic determinations show inferred evolutionary relationships in the form of multiple branching lineages connected by nodes. So, the sequences can easily be identified at the end of branches. And these taxonomic determinations were made based on the general lineage species concept.
Hence, I will add the following statement:
Taxonomic determinations were made based on the general lineage species concept.

While all zebras have stripes, no two zebras share the same pattern. Variation, overpopulation or adaptation
Answer:
Variation
Explanation:
"Overpopulation" describes an issue in which there are too many of a certain organism.
"Adaptation" describes a phenomena where an organism evolves to adapt in its environment.
Well, lets compare zebra stripes to fingerprints. Fingerprints have nothing to do with overpopulation, and unique fingerprint patterns have nothing to do with adaptation, but the seemingly infinite variation in both fingerprints and zebra stripes is definitely there. So, the uniqueness of the patterns throughout each zebra individual is variation.
