"alejandro had his cholesterol checked recently. his results showed a total blood cholesterol concentration of 260 mg/dl. based
Setler [38]

Answer:

The correct answer would be - high risk of developing CHD.

Explanation:

Every animal and humans need some cholesterol to regulate bodily functions such as creating hormones, vitamin d forming, cell membrane and many more. But if someone have too much cholesterol in his body, he must have developed a higher risk of coronary heart diseases or CHD.

The total cholesterol level under 200 mg/dL (milligrams per deciliter) is classified as normal for the adults. Reading between 200 to 239 mg/dL is considered as a borderline where is above 240 mg/dL is considered as high. Alejandro's reading falls under high cholesterol level so he has a higher risk of developing CHD.

Thus, the correct answer is - a higher risk of developing CHD.

Why are sedimentary rocks found as a veneer
anyanavicka [17]
Sedimentary rocks are made from eroding other rocks and they are deposited on other rocks, they are younger than the underlaying rocks hence could only be formed on older underlaying rocks. If u have any more questions feel free to ask!

Karolina [17]

Answer:

This is what I put (its kinda bad so don't judge)

Explanation:

A) Examining Table 1 with cancerous cells and HeLa cells we can see that with both HeLa and cancerous cells when treated with EGF increase in cells. Examining Table 2 we can see that HeLa cells create the most cells when treated with a concentration of 25 ug of EGF.

B) Normal cells increased by 33 when treated with a concentration of 10 ug of EGF. Cancerous cells increased by 405 when treated with a concentration of 10 ug of EGF. We can conclude from this that the cancerous cells multiply faster than normal cells with  a concentration of 10 ug of EGF.  

C) The mitotic index of HeLa cells with zero EGF treatment is 11 mitotic figures noted per 73 high power fields. The mitotic index of HeLa cells with 10 ug of EGF treatment is 8 mitotic figures noted per 90 high power fields. The mitotic index of cancerous cells with zero EGF treatment is 22 mitotic figures noted per 60 high power fields. The mitotic index of cancerous cells with 10 ug of EGF treatment is 27 mitotic figures noted per 465high power fields.
