Answer:
A. 60 grams protein
B. 74 grams of protein
Explanation:
The amount of protein needed depends on weight and lifestyle. The daily minimum recommended by the National Institutes of Health is 0.36 grams per pound for a sedentary person. But the daily optimal intake for this same sedentary person is 0,8 grams of protein per kg of body weight. On the other hand hand, adults with a more active lifestyle need more protein in their body, the intake should be between 1,2 and 2,0 grams of protein per kg. For example, endurance runners need up to 1,4 and strength training athletes need up to 1.8 g of protein per kg.
The first step for calculating protein requirements is calculate the weight in kilograms, so we need to divide the weight in pounds by 2,2.
154lb/2,2= 70 kilograms
Then we have to multiply the weight in kg, times the number of protein needed per day, 0,8 for a sedentary healthy adult.
70kg x 0,8= 56 grams
Part A:
165-pound (lb) male who is healthy but sedentary
165 lb/2.2 = 75 kg
75 kg x 0,8 = 60 grams protein per day
Part B. Sarah is moderately active so we need to use a number between 1,2 and 2, since shes active but not very active we can use the 1,2.
136-lb/2,2= 62 kg
62 kg x 1,2 = 74 grams of protein
Answer:
two capillary beds
Explanation:
Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.
Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU
