Answer:
False
Explanation:
Gregor Mendel, who was referred to as the FATHER OF GENETICS, discovered the principles that governs heredity. One of those principles which he called LAW OF INDEPENDENT ASSORTMENT states that the alleles of a gene randomly segregates into gametes independently of the alleles of another gene. This means that during gamete formation (meiosis), the separation of the alleles of one gene doesn't affect the separation of the alleles of another gene.
Mendel discovered this principle when he worked with two genes that was responsible for two distinct characters. Hence, in a cell that contains two genes responsible for two different characters in the organism, independent assortment will always occur during gamete formation. Although, in an organism that is homozygous for both traits (AABB or aabb), only one type of allelic combination will be produced in the gamete. However, the alleles will still randomly align and separate independently of one another during Metaphase and Anaphase stages of meiosis.
Answer:
An Optic Chiasm
Explanation:
The optic chiasm is an X-shaped structure formed by the crossing of the optic nerves in the brain. The optic nerve connects the brain to the eye. This can affect vision.
I’m pretty sure the answer is agar.
Answer:
The option which is not responsible for the cause of urban migration is the search for suitable land for agriculture. Hence the answer is option D.
Explanation:
The land for agricultural use is available in rural areas and it is not available in urban areas. The land in urban areas is suitable for infrastructure and buildings and houses. Hence there is no land available for the agriculture purpose.
Also, we know that there is much pollution in urban areas which is not suitable for the growth of crops. In rural areas the atmosphere and all the condition is favorable for the growth of crops. Hence, we can see that it is not a cause for migration to urban areas.
