Answers
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.

Why is there a higher rate of skin cancer in Australia than in other
parts of the world?
Answers
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
Answers
Answer:
The answer is C.

the screws and nails that hold your desk together
Answers
Answer:
The correct answer is - 1. a metal hammer
4. the metal frame of your chair
6. the screws and nails that hold your desk together.
Explanation:
Bar magnets are rectangular objects made up of ferromagnetic objects or substances and must carry the north and south pole ends. These objects show ferromagnetism and attract any ferromagnetic metal such as iron, steel or ferromagnetic composite.
In the case of the same ends, for instance, the north-north pole of two magnets repulse and opposite attract to one another. From the given options the correct answer is a metal hammer, the metal frame of chair and screws and nails that hold the desk.

Describe how the lizard population is changing
Answers
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.

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.
Answers
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

Answers
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.

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
Answers
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.
