What factor distinguishes the experimental group from the control group

1 answer:

7 0

A control group take no part in any experiment, they simply do what they do normally in order to compare the results from someone who has done something differently (experiment) and someone who hasn't. Hope this helps

the __________ __________ is made up of two concentric membranes and is continuous with the membrane of the endoplasmic reticulu

Kobotan [32]

Answer:

The nuclear envelope is composed of two concentric lipid bilayer membranes separated by an intermembrane space of about 20-40 nm. The outer membrane is continuous in many places with the rough endoplasmic reticulum. Like the rough ER the outer membrane of the nuclear envelope is dotted with ribosomes.

A botanist has acquired a group of sweet pea plants. All of the plants have yellow pea pods (the recessive trait), except for on

Julli [10]

Answer:

Cross the green-pod plant with a yellow-pod plant.

Explanation:

To determine the zygosity of a particular individual, the best way is to cross it with a phenotypically recessive individual.

Such a cross in which an individual with unknown zygosity possessing a dominant trait is crossed with an individual possessing a recessive trait is termed as a test cross.

Therefore, in the given situation the zygosity of the green pod needs to be determined and the green pod is a dominant character. Further, it is given that a yellow pod is a recessive trait, therefore a test cross can be performed between the green pod and yellow pod, and then the offsprings can be observed.

if the offsprings are all phenotypically dominant then the green pod is homozygous and if there are phenotypically recessive offspring also present then the green pod is heterozygous genotypically.

Mountain ranges form along ___ plate boundaries via orogenic processes.

Tamiku [17]

1. Mountain ranges form along convergent plate boundaries via orogenic processes.

<h3>What is tectonic plates?</h3>

The formation of mountains is caused by tectonic plates. A mountain is formed when two tectonic plates move towards each other and collide, resulting in altitudes that can take years to reach but that eventually create massive mountains through what are known as convergent plate borders.

2. Rift valleys formed through the stretching of divergent plates occurs through a divergent boundary process.

When tectonic plates separate, they can leave low ground areas like the Rift Valley, which are produced by diverging continental plate borders. They can be found on the surface of the Earth or at the bottom of the ocean, and they are formed by the expansion of the seabed.

3. The formation of mountain ranges occurs as a result of orogeny.

This process occurs when one continental plate dips and the other rises, allowing mountain ranges to form. Orogeny is the name given to this process.

4. Scientists observe an extremely long deformation area in a continental plate during an orogenic process..

Scientists use tectonic plate simulations to study this deformation in order to better predict natural disasters such as earthquakes.

5. Epeirogenic process causes vertical plate motion along tectonic plates.

The vertical movement of a continent that generates soft arcs or rises parts uniformly is known as epeirogeny.
