Hello!
Glad to tell you that you answer will be A.
Only Eukaryotic Cells have DNA which is stored inside of the nucleus. If the cell contains no DNA, then it has no need for a nucleus.
Hope You Pass Your Test!!
Answer: The right answer is -
A) Gene flow
Explanation:
Gene flow is a process of gene migration or the transfer of gene variant (also called allele, which is responsible for genetic variation in population) from one population to another population.
As a consequence of gene migration, new alleles are introduced or added in the already existing population, thereby increasing genetic diversity.
Thus, option A) is the right answer.
Answer:
(look at the explanation below)
Explanation:
A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages.
Answer:
Elements: H (hydrogen) He (helium) Li (lithium) Be (beryllium) B (boron)
compounds: H2O (water) H2O2 (Hydrogen peroxide) NsHCO3 (baking soda) NaCI (salt)
Element compound or mixture?: 1. Element 2. compound 3. Mixture of elements 4. mixture of compounds 5. mixture of elements and compounds.
Rewrite the sentences:
1. all matter is made up of tiny particles calles atoms and molecules
2. right
3. right
4. compounds are chemically joined together
task 2:
1. i know this is element
2. i know this is compound
3. i know this is mixture
task 3:
In this lesson i have learned that Atoms are in everything and are what makes up most of the stuff on earth. They are tiny molecules that make up me and everything around me. I have also learned that atoms are made up of Elements. Elements are chemical molecules that make up things like the air we breathe. However, when more than one element joins together a compound is formed. Compounds make up more physical things around me such as drinking water and salt for cooking. When many different compounds are joined together a mixture is formed. An example of a mixture can be sand and water.

Explanation:
The physiology of the brain is closely related to how we think and feel. The limbic system in the brain, for example, is the center of all our emotions. Understanding how this part of the brain functions will greatly help in understanding the psychology of the human being. There are certain hormones that have an affect on our moods and behavior so it is important to gain knowledge of physiology and genetics in order to grasp the science behind emotional responses, memory etc.
