Answer:
Hey there!
Some consequences would be rising sea levels, hotter summers, colder winters, melting icecaps.
Hope this helps :)
Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.
In dim light, the iris expands the pupil to allow more light to enter the eye. So, when we come out of a darkroom into the bright sunlight, a large amount of light enters into our eyes and due to glare feeling, we are not able to see the things clearly. Gradually, the iris contracts the pupil to allow less light to enter the eye to see the objects clearly. It take some time for the pupil.For that time interval, person is unable to see the things.
Answer:
A. The new cells each receive an exact copy of all the chromosomes from the original cell.
Explanation:
Answer a)
The students should only have changed one variable to test for germination of seeds. They should have just changed the seed types and rest all factors like temp, pH should be kept constant for all of them.
Answer b)
The procedure could be changed as follows. The students should place three of each types of seeds in the petri dish. They should keep all the conditions like nutrients, temperature, pH constant for all the three dishes. After this observations should be made to check which seed germinates faster.
