If a student had a single peanut before this lab, how many times would a student have to run upstairs in order to burn the energ

If the student has mass 75 kg, and if the stairs are 3 m high, then 
<span>work = mgh = 75kg * 9.8m/s² * 3m = 2200 J </span>
<span>so I'd say "one one-hundredth." </span>

Because the fish are now able to swim in deep water, their ___________ in shallower water will have less food. Likewise, competi
aliina [53]

Answer: Predators, increase

Explanation:

Because the fish are now able to swim in deep water, their Predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.

Predation is the biological term used to describe the interaction between organisms whereby one  organism which is a Predator kills and devour another organism which is its prey.

In shallow waters, Fishes are more susceptible to predators like man, eagle etc who catch and kill them and  because of that many of these fishes have acquired anti--predator adaptations to prevent being caught and killed and so are now able to swim in deep waters leading to the predators having less food. The fishes who can now swim deep into waters  will increase the already populated deepwater and will cause an increase in competition for the fishes that eat same type of food with the new fishes

Why does an adult plant require more water than a baby plant?
ASHA 777 [7]

Superficial and tender roots require more water to encourage root stability and development.

Grown plants don't need water as often; rather, they need a bigger part at one time so that the established roots can flourish deep in the ground.

<h3>Why do plant cells that transport water against the force of gravity contain many more mitochondria than other plant cells?</h3>

The mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration take place.

The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane.

The mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.

Thus, Superficial and tender roots require more water to encourage root stability and development.

In a two-point test cross, 36 of the offspring were recombinant types. The remaining 64 offspring were parental types. How many
Maksim231197 [3]

Answer:

36

Explanation:

A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
