<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
1) cells are the smallest units of life
2) living organisms are made up of cells
3) all cells come from existing cells
Answer:
The Gram-negative diplococci <u>Neisseria </u>are pathogenic microbes that infect mammalian mucous membranes, and include the species which causes gonorrhea.
Explanation:
Options for this question are:
- <em>Streptococcus
.</em>
- <em>Coxiella
.</em>
- <em>Neisseria
.</em>
- <em>Listeria
.</em>
- <em>Haemophilus.</em>
Bacteria of the genus Neisseria are Gram-negative, with a rounded morphology that are associated in pairs, so they are called diplococci. They are aerobic microorganisms, no more than 1 micrometer in diameter, immobile and not sporulated.
Their biological importance is due to the fact that they cause diseases in humans, such as bacterial meningitis -caused by N. meningitidis- or gonorrhea, associated with N. gonorrhoeae.
