It increases the rate of a chemical reaction.
Answer:
The correct answer would be : formed nucleus is that of Mn.
Explanation:
Alpha decay is a process that is exhibited by unstable molecules to be more stable. During the alpha decay nucleus of the unstable element removes its two protons and two neutrons in a bundle that researchers call an alpha molecule.
Since a particle loses two protons during alpha decay, it changes starting with one component then onto the next.
Co has 27 protons and neutron in its nucleus emits a alpha molecules that contain 2 protons and 2 neutrons
27=2+z
z =25 in periodic table 25 atomic number of Mn.
Thus, the correct answer would be : formed nucleus is that of Mn.
Answer:
It represents an acceleration.
Explanation:
The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. If the line slopes upward from left to right, this means the object is speeding up.
Answer:
a. Coded for on the X and Y chromosomes
b. Coded for on the X but not Y chromosome
c. Coded for on the Y but not X chromosome
Explanation:
The X and Y chromosomes are the sex chromosomes as they are involved in sex determination. All the genes that are present on the X and Y chromosomes are inherited along with these chromosomes and therefore, exhibit sex-linked inheritance.
X and Y chromosomes share a homologous region. Therefore, the sex-linked genes are defined as the ones present on both X and Y chromosomes as well as the ones that are present on either X or Y chromosomes.
For example, the gene for hemophilia is present on the X chromosome; but not on the Y chromosome. The SRY gene is present only on the Y chromosome.
