Answer:

to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Explanation:

Firstly, let us calculate the number of calories burnt in 2 hours

in 10 minutes; 30 calories are burnt

∴ in 1 minute 30/10  calories are burnt = 3 calories are burnt

2 hours = 120 minute

∴ in 120 minutes 3 × 120 = 360 calories are burnt.

Next, let us calculate the amount of trail mix that contains 360 calories

100g of trail mix = 450 calories

450 calories = 100 g

1 calory = 100/450

∴ 360 calories = 360 × (100/450)

=  360 × 0.222 = 80g

∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Which of the following is true concerning cancer cells?
Iteru [2.4K]

Answer:

a.They evade the normal controls that trigger programmed cell death.

Explanation:

Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.

Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.

How closely do Mendel insights into dominant and recessives traits match up with the ratios that punnett calculated in his Punne
elena-14-01-66 [18.8K]

Answer:

Perfectly in theory, except there is chance involved

Explanation:

The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.

However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.

However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
