Which of the following units is used in the household measurement system?
At what blood alcohol level do most social drinkers quit drinking?
Rachel grows pea plants in her backyard. Some of the pea plants have purple flowers, whereas others have white flowers. What does this indicate about Rachel's pea plants?
Answer: The correct answer would be "the plants have genetic variation for flower color".
Genetic variation, as the name suggests, refers to the variety or differences present at gene or DNA level among different individuals or population.
More the genetic variation more are the traits or phenotype of the characters.
Different in DNA sequences and different combination of alleles or genes lead to increase in genetic variation.
For example,different shape, size, colors, appearance, texture, et cetera.
Similarly, the different flower colors also show the presence of genetic variation in a population.
Different combination of alleles lead to expression of different flower colors such as purple and white.
What characteristics of DNA results in cell differentiation in developing embryos? A. What protein is produced by a gene.
B. Which genes are active.
C. How many copies of each gene are present.
D. Which genes are present.
The correct option is B. Which genes are active.
Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.
But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.
Hope this helps!
Your hair is composed of live cells that need vitamins and nutrients. Please select the best answer from the choices provided.
false. ur hair is made of up dead cells
false just took the test and because your hair is made up of dead cells
How does water change earth surface?
Water can affect the surface by erosion because over time it slowly carries away dirt and rock. This is how the Grand Canyon was created. The Colorado River slowly carried away rock and earth to create the Grand Canyon that we know today.
Rainwater Causes Weathering and Erosion, Rainwater Causes Deposition, Deposition Helps Form New Rocks, River Water Weathers and Erodes and Ice Causes Weathering and Erosion
Twenty points Which movement of molecules would be most affected by a disorder that causes damage to carrier proteins Osmosis
The answer would be Active Transport
A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects. The 1st group of dogs receives plain water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd group receives 50 mg of caffeine each. He will measure their activity levels by recording how long each dog runs without stopping, after giving them the pills. What is the control group in this experiment?
The control group are the dogs that receive plain water
In every research experiment we need a standard or control group in which we can compare the effects of the treatments. The control group is tested in normal conditions (we always know what’s is going to happen), in this case, the normal condition is that the dog dirk plain water. The tested group is in which we want to know the effect of the treatment, we do not know what is going to happen ( we want to know what happen if the dog consumes caffeine before runs).
We all have different forms of genes from our parent(s).what are these different forms called? A.alleles
the answer is allele
Allele. Genes come in more than one form. The different forms are called alleles.
