Meiosis is a kind of cell division.
it's used to reduce half of the chromosomes and prodouce 4 gamete cells, which we call these cells haploid.
for example, it is used in human reproduction, for the sperm and ovum, in order to have a sexual reproduction.
the offspring of them are genetically non identical to the parent.
This finding indicates the damage of the mid-brain
This is evident due to the Decerebrate posturing, which is characterized by abnormal extension in response to painful stimuli, that indicates damage of the midbrain. On the other hand, damage to the diencephalon or cortex, abnormal flexion, occurs when a painful stimulus is applied. While medulla damage results in flaccidity.
<h2>Gram Negative and Positive Bacteria</h2>
Explanation:
- The cell wall of <em>gram-positive bacteria is a peptidoglycan macromolecule </em>with joined adornment molecules, for example,<em> teichoic acids, teichuronic acids, polyphosphates, or sugars</em>
- <em>Gram-negative bacteria</em> organisms are not destroyed by specific cleansers which easily <em>kill Gram-positive bacteria </em>
- Surface displayed proteins on microbes play key role in <em>pathogenesis </em>as they elevate bacterial attachment to have tissues, acquisition of essential nutrients, evasion and suppression of<em> immune response and host cell entry</em>
