Answer: Unlike other bacteria listeria germ usually grow and spread in the refrigerator thereby contaminating the refrigerator and spread to the foods stored in the refrigerator
Listeria are known to be causative agent of rare bacterial
diseases called listeriosis. This infection are usually caused by eaten foods
that are contaminated by listeria.Thus, Listeria can cause serious illness in
newborns , pregnant women and adult with weaked immune system. unlike other
bacteria listeria germ usually grow and spread in the refrigerator thereby
contaminating the refrigerator and spread to the foods stored in the
refrigerator which consequently cause sickness in the family.
Answer:
The Serengeti is a vast ecosystem in east-central Africa.
Explanation:
I know how to do punnet square. What is the problem?
N the brain<span>, dopamine functions as a </span>neurotransmitter<span>—a chemical released by </span>neurons<span> (nerve cells) to send signals to other nerve cells. The brain includes several distinct </span>dopamine pathways<span>, one of which plays a major role in </span>reward-motivated behavior<span>. Most types of rewards increase the level of dopamine in the brain, and many </span>addictive<span> drugs increase dopamine neuronal activity. Other brain dopamine pathways are involved in </span>motor control<span> and in controlling the release of various hormones. These pathways and </span>cell groups<span> form a dopamine system which is </span>neuromodulatory<span>.</span>
Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.
Explanation:
Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.
Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.
Failure of separation or segregation of:
- Homologous chromosomes occur in Anaphase I, affects four daughter cells.
- Sister chromatids during Anaphase II, affects two daughter cells
This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.
