There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?

Answers

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

The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?


Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.​

Answers

Answer:

earthquakes occur when the edges suddenly become unstuck and slip along a fault

Which of the following changes takes place during the third trimester of a womans pregnancy

A.) the fetus begins to form teeth
B.) the fetus develops toenails,lips, and eyelashes
C.)The mothers uterine contractions begin
D.) the fetus’s hands and feet appear

Answers

Answer:D

Explanation:

The fetus develops toenails, lips, and eyelashes is the change that takes place during the third trimester of a woman's pregnancy.  Therefore, option (B) is correct.

What happens in third trimester?

By the third trimester, which begins around the 28th week of pregnancy and lasts until birth, the fetus has already formed most of its organs and body parts. During this stage of pregnancy, the fetus undergoes significant growth and development. This includes the development of toenails, lips, and eyelashes. Additionally, the fetus begins to accumulate body fat, and its brain undergoes rapid development.

To answer the other options, the formation of teeth begins during the embryonic stage, which occurs in the first trimester. The mother's uterine contractions typically do not begin until labor, which occurs at the end of the third trimester or later. The fetus's hands and feet appear during the embryonic stage, specifically around the 6th week of pregnancy.

Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?

Answers

Answer:

The correct answer would be - 25%.

Explanation:

It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.

BbTt is a heterozygous condition and a cross with itself will produce :

Gametes: BT Bt bT and bt

          BT       Bt       bT       bt

BT     BBTT   BBTt   BbTT   BbTt

Bt      BBTt    BBtt    BbTt   Bbtt

bT     BbTT   BbTt    bbTT   bbTt

bt      BbTt     Bbtt    bbTt     bbtt

Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

How does the tRNA-mRNA interaction ensure that the amino acids are added in the correct order?

Answers

Answer:

Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA.

This system ensures that amino acids are added to the chain in the correct order. At the beginning of translation, the ribosome and a tRNA attach to the mRNA.

Perennial plants in the genus Asclepias (milkweeds) contain compounds called cardiac glucosides (cardenolides) that can be toxic for animals. Monarch butterfly larvae feed on Asciepias sp. but are not harmed by the cardenolides. Instead these molecules accumulate in the tissues of the caterpillar and are present in the tissues of the adult butterfly. Because of these toxins in their tissues, Monarch butterflies are unpalatable to insectivorous birds. Another species of butterfly, the Viceroy, looks very similar to the Monarch in its bright coloration and distinctive patterning but was thought to lack a toxin. Because Monarch butterflies are toxic it was long thought that the similar appearance of nontoxic Viceroy butterflies was an example of:

Batesian mimicry

Explanation:

Batesian mimicry refers to a form of biological resemblance by which a harmless prey species evolved in order to imitate another harmful species for a common predator, thereby increasing its chances of survival. This defensive behavior was described by Henry W. Bates, who made ecological observations of butterflies in the Brazilian rainforest. Thus, an innocuous species that show harmful signals against a predator will gain protection against this predator. Batesian mimicry is a type of mimicry that benefits from the predator's learned avoidance behavior.
