Answer:
1. law of Independent Assortment; metaphase I; independent of.
2. law of Segregation; meiosis I; in separate gametes.
Explanation:
Between 1856 and 1863, Gregor Mendel developed a series of mating experiments using pea plants, which enabled the discovery of some basic principles of inheritance. These principles/laws are stated as:
1) Law of segregation: this principle states that the inheritance pattern of phenotypic traits is characterized by the presence of a gene pair and each gamete carries only one allele for each gene pair so offspring inherit one gene variant (allele) from each parent
2) Law of independent assortment: this principle states that the genes responsible for the inheritance pattern of different traits are independently sorted from one another and thereby different traits are independent one from another.
3) Law of dominance: this principle states that the dominant allele will always be expressed in heterozygous individuals (this law is only applicable in cases of complete dominance).
The last stage of embryonic development where the embryonic stem cells are found is the blastocycst. In this stage the cell differentiates and group themselves into different body parts and specialized cells. This stage is reached with in the period of 3 to 5 days of the embryo development.
Answer:
Yes
Explanation:
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. ... Elemental mercury is an element that has not reacted with another substance.
Answer:
Vascular dementia
Explanation:
This is a neurologic condition that is brought about as a result a brain injury caused by ischemic damage e.g ischemic damage with atherosclerosis. Vascular dementia is disease of no known cure but it's effect can be treated or suppressed. It is characterized by patient or client suffering from it to have loss of memory, laughing or crying when it's unnecessary or at awkward times e.t.c it occurs as a result of damage of blood vessels in our brain or break down and it occurs as a result of stroke, diabetes and other factors.
Answer:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base., thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges.
