Imagine that a researcher claimed to have created a genetically modified plant that produces twice as much energy as it harnesse

s from its environment. how could this be possible

Virty [35]3 years ago

According to the Law of Conservation of Energy, energy is neither created nor destroyed. Technically, it is impossible for the plant to produce energy twice this input. It could only be possible if an external energy is required to create a reaction that would create more energy. This external energy could in the form of energy or another chemical containing potential energy.

What variables should the scientists control in the experiment
Drupady [299]

Answer:

It's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variable. When possible, control variables should be identified, measured, and recorded.

Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of the following
kodGreya [7K]

Answer:

a video that shows penguin species that have different mating dances

Explanation:

The question is incomplete as it does not have the options which are:

  • a video that shows a large river that has penguin populations on both sides
  • a video that shows penguin species that have different mating dances
  • a video that shows a penguin that is laying eggs
  • a video that shows penguins in a tidal pool and an open ocean

Answer:

a video that shows penguin species that have different mating dances

<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>

<em><u /></em>

<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>

<em><u /></em>

<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>

<em><u /></em>

<em><u>Thus, the selected option is correct.</u></em>

<h3><em><u /></em></h3>

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers
fredd [130]

Answer:

we will know that the allelic frequencies are for R 0.95 and r 0.05

Explanation:

We know that the population is in Hardy-Winberg equilibrium, we deduce the following formula:

p + q = 1

p2 + 2pq + q2 = 1

data

R: red flower allele

r: allele blor blanca

p would be equal to the allelic frequency R

q will be equal to the frequency allelic r

2p = RR

2q = rr

2pq = Rr

If there are 25 white flowers in 1000 plants, their frequency will be:

2pq frequency of the Rr genotype

white flower = 25/10000 = 0.0025 = rr = 2q = 0.0025

we deduce that q is equal to 0.05

we replace the data with the previous formula

p + q = 1

p = 1-0.05

we get as a result

  p = 0.95

if p = 0.95 and q = 0.05

we will know that the allelic frequencies are for R 0.95 and r 0.05

13. Which layer would have the oldest fossils, a layer deep underground or a layer close to
Irina-Kira [14]

Answer:

I believe a layer deep underground would have older things, because the ground could erode over time causing the fossil to sink into the ground.
