c. glucose, energy
d. glucose, oxygen

Answers

Answer:

C. glucose, energy

Explanation:

Glucose is ‘raw material’ in cellular respiration. It passes through the glycolysis cycle, in the cytoplasm of the cell. This occurs in virtually all cells. In eukaryotic cells, with mitochondria, the product of glycolysis (usually pyruvate) is channeled to the organelle and pass through the Citric acid /Krebs cycle that produces even more ATPs than glycolysis.

An individual invested $5,000 into two accounts. They placed part of it into an account that earned 4.5% and the rest in an account that earned 6%. The total annual income generated from this investment in simple interest was $270. How much was invested in each account?

Answers

Based on the total annual income from simple interest, $2000 was invested in Account 1 while $3000 was invested in Account 2.

What is simple interest?

Simple interest the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest = Principal × rate × time

In simple interest, the principal amount is always the same.

Given that the principal is $5000

This amount was invested into two account at the following rates:

Account 1 at 4.5% interest rate

Account 2 at 6% interest rate

Total income from simple interest = $250

Let amount invested in Account 1 be y; amount invested in Account 2 will be 5000 - y

Interest on Account 1 = y × 4.5% × 1 = 0.045y

Interest on Account 2 = (5000 - y) × 6% × 1 = 300 - 0

06y

0.045 y - 0.06y + 300 = 270

-0.015 y = -30

y = 2000

5000 - y = 3000

Therefore, $2000 was invested in Account 1 while $3000 was invested in Account 2.

Answers

Several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.

What are the differences between the mammoth and the elephant?

The mammoth is an animal that was once extinct and belonged to the genus Mammuthus and the family Elephantidae which included the proboscidians. Elephants differ from mammoths in that mammoths had their bodies covered with hair. Also, elephants are slightly smaller than mammoths.

What are the differences between the mastodon and the elephant?

Both were herbivores, but the mastodons had conical-shaped teeth designed to crush leaves and branches more easily. Mammoths had rough molars, allowing them to cut through vegetation and graze like modern elephants.

Whit this information, we can conclude that several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.
