Why isn't mitochondrial DNA a unique identifier? a. Mitochondrial DNA is inherited through the maternal lineage. b. All female offspring inherit their mother's mitochondria, and therefore the same mitochondrial DNA. c. As a result, all female family members that share a maternal lineage would have the same mitochondrial DNA. d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual. e. All offspring inherit their father's mitochondria, and therefore the same mitochondrial DNA.

A mutated sperm cell will always be destroyed during meiosis before it leaves the testes, while skin mutations remain within the skin.
There is little chance that a sperm mutation will affect the testes, while skin mutations almost always develop into cancer.
The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
Answers
Answer:
The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
Explanation:
There are two types of mutations: germline mutations (which affect the ovules or sperm), and somatic mutations (they occur in certain cells, for example, in the skin). Each one is defined below:
-Germinal mutations are inherited from a parent and are present throughout life in each cell of the body. These mutations are located in the ovules or sperm of the parents and are transmitted as inherited mutations.
-Somatic mutations can occur at any given time and only in certain cells. These mutations may be due to, for example, environmental factors, such as radiation from the sun, in this case affecting skin cells. These types of acquired mutations are not transmitted to the next generation.

A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.
Answer : According to the octet rule, sodium wants to lose an electron.
Explanation :
The given element is sodium with atomic number 11 that means it has 11 electrons.
The electronic configuration of sodium will be,
From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.
According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).
Hence, according to the octet rule, sodium wants to lose an electron.

diffusion occurs due to differences in concentration of substances in different regions. then substances will naturally spread out (due to innate Brownian kinetic energy). the spreading I. e. diffusion will stop until equilibrium is achieved.
note: those substance particles are still moving due to the innate Brownian kinetic energies!
Final answer:
Diffusion is the process where molecules move from higher to lower concentration areas. It continues until a state of equilibrium is reached, at which the particles continue to move but their distribution remains constant.
Explanation:
In biological terms, diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This passive movement continues until it reaches a state we refer to as equilibrium. At equilibrium, there is a uniform concentration across the space, and diffusion continues, albeit without any net change, as particles continue to move randomly but their overall distribution remains constant.
