Suppose that we study a gene that has been linked to coronary heart disease. We find in a pilot study that in subjects with the

C/ C genotype 20 events have occurred in 200 individuals over a period of 10 years, whereas in subjects with the T/ T genotype 30 events have occurred in 250 individuals in 10 years. Which genotype appears to be associated with a higher prevalence of heart disease?

Answer:

T/ T genotype

Explanation:

To know which genotype appears to be associated with a higher prevalence of heart disease, you must know which genotype appeared in the highest percentage in the population tested.

For this, we will do the following calculations.

  • C/C Genotype:

200 people = 100%

20 people = X

X = (20 * 100) / 200

X = 10%

This means that the C/C genotype appeared in 10% of the tested population.

Now we must to know the percentage of the T / T genotype, we must consider 200 of the 250 people tested.

  • T/T Genotype:

250 people = 100%

200 people = x

X = (200 * 100) / 250

X = 80%

----

200 people = 80%

30 people = X

X = (30 * 80) / 200

X = 12%

Thus, we can say that the T / T genotype appeared in a higher percentage within the tested population, being considered the genotype that seems to be associated with a higher prevalence of heart disease.

What is the smallest or most specific level of organization organization you and your neighbors all have in common
bixtya [17]

Answer:

The cell

Explanation:

<em>The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is </em><em>the cell.</em>

This is in accordance with the cell theory which has three basic components, including:

1. The cell is the basic unit of life

2. All living organisms are made up cells

3. Cells arose from pre-exsiting cells.

<u>Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.</u>

Is autism more common in a certain group of people?
Inessa [10]

Answer:

Explanation:

# Boys are four times more likely to be diagnosed with autism than girls.

# Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.

# 31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).

# Autism affects all ethnic and socioeconomic groups.

# Minority groups tend to be diagnosed later and less often.

# Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.

# There is no medical detection for autism.

If a wildfire destroyed all the trees in a forest, what might happen to the ecosystem? Select all that apply.
bija089 [108]
Okay, I googled it because I wasn’t sure but, according to the article *ahem* “Destructive as forest fires may seem, forests often regrow in their wake. In some cases, however, forest fires become so intense they cause severe damage to the soil that may take years or even decades to repair”.

Hope this helped!

nlexa [21]

Answer:

The onset of puberty  in girls by the release of these two hormone is an example of typical signal transduction pathway

Explanation:

Specifically Luteinizing Hormone (LH)  along with the Follicle stimulating Hormone (FSH) released from pituitary gland gets attached to the receptors present in the cells of ovary and generate a series of chemical reaction or cascade of biochemical reaction in a cell (activation of secondary messengers like cAMP) to produce estrogen and progestrone that will help in follicle formation and ovum maturation.
