A nurse is talking about an essential mineral that is stored in human bone. which mineral is the nurse describing?

1 answer:

7 0

There are actually 2 kinds of minerals mainly in our human bone. They're calcium and phosphorus.
There are also other types of minerals, but they're in very small amounts. Mainly are those 2.
We can take in these 2 minerals by eating food such as diary foods, meat, eggs etc.
Also, if we have a lack of intake of calcium or phosphorus, one of the deficiency disease can be rickets, like soft bones, legs may bend outside as a child or bones may crack easily in adults.

Answer:

1. False

2. True

3. True

4. True

Explanation:

Negative feedback (or balancing feedback) happens when some capacity of the yield of a framework, cycle, or system is taken care of in a way that will in general decrease the variances in the yield, regardless of whether brought about by changes in the input or by different unsettling influences.

Though certain feedback will in general prompt unsteadiness through outstanding development, wavering or disorganized conduct, negative feedback for the most part advances steadiness. Negative feedback will in general elevate a settling to balance, and diminishes the impacts of bothers. Negative feedback loops in which the perfect measure of adjustment is applied with ideal planning can be entirely steady, exact, and responsive.

According to Mendel’s law of dominance, we would expect _________ percent of the offspring to have white flowers.

Marysya12 [62]

Answer: The correct answer for the fill in the blank is A) Zero.

According to Mendel's law of dominance, in a cross between parents that are true breeding for a contrasting trait (like plant with pure purple and white flowers), only one form is expressed in the next generation and that form is called dominant trait.

As per the Mendelian inheritance, purple flower color is dominant over white flower color. When parents that are pure breeding for purple and white flower ( PP and pp) are crossed, they will produce all purple flowers ( Pp) in the first generation as purple is dominant trait.

Thus, percent of offsprings with white flowers is zero.

In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of

Oksana_A [137]

Answer:

What are the allele frequencies in this population?

Frequency of S = 0.625
Frequency of s = 0.375

In the next generation of 1000 hamsters, what are the expected genotype frequencies?

Frequency (SS) = 0.39
Frequency (Ss) = 0.47
Frequency (ss) = 0.14

What are the expected number of each genotype in the next 1000 hamsters?

Individuals SS = 390
Individuals Ss = 469
Individuals ss = 140

Have the allele frequencies changed? No, they are the same

Is the population in Hardy-Weinberg equilibrium? Yes, it is.

The expected genotype frequency of Ss (2pq) in the next generation is expected to be: 0.469 (option a)

The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is: 390
