Details about Neurotransmitters are described below.
Explanation:
1.Neurotransmitters are referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles.
2.Terms in this set
- acetylcholine. A neurotransmitter used by neurons in the PNS and CNS in the control of functions ranging from muscle contraction and heart rate to digestion and memory.
- norepinephrine.
- serotonin.
- dopamine.
- GABA.
- glutamate.
- endorphin.
3.Neurotransmitters are made of the following :
- The amino acid neurotransmitters glutamate, GABA (γ-aminobutyric acid), and glycine. All of these are amino acids, though GABA is not an amino acid that's found in proteins. ...
- The biogenic amines dopamine, norepinephrine, epinephrine, serotonin, and histamine, which are made from amino acid precursors.
4.Neurotransmitters can impact a specific area of the brain, including behavior or mood, their malfunctions can cause effects ranging from mood swings to aggression and anxiety. ... Understanding the way neurotransmitters function in the brain could lead to better treatments for mental disorders.
Answer:
by testcrossing with a homozygous recessive partner
Explanation:
<u>If a pet cockroach exists whose zygosity is unknown, this can be determined by a test cross. A test cross involves crossing an organisms whose zygosity is unknown with a partner that is homozygous recessive for the same trait.</u>
Let us assume that brown body is represented by the allele B, the dominant allele. The homozygous recessive version would be bb.
The genotype of a brown cockroach whose zygosity is not known can be denoted as B_, where '_' can be a 'B' or a 'b'.
When B_ is crossed with bb:
B_ x bb
Progeny
2 Bb
2 _b
The phenotype of Bb would be brown (since B is dominant over b) while the phenotype of _b would depend on the zygosity level of the cockroach.
If the unknown genotype is BB, then _b becomes Bb and the phenotype will be a brown body. This means that all the progeny will appear brown. (<em>see the first attached image for the Punnet's square</em>)
In other word, if the unknown genotype is bb, then _b becomes bb and the phenotype will be a alternate color (non-brown) body. This means that 50% of the progeny will appear brown while the remaining 50% will be in the alternate color. (<em>attached</em>
Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis.
This is because toxins are ingested by organisms and accumulate in the fatty tissues. Theses toxins then become more concentrated in successive trophic levels of a food web biological magnification. Magnification occurs because the biomass at any given trophic level is produced from a much larger biomass ingested from the level below and therefore, top-level carnivores tend to be the organisms most severely affected by toxic compounds.
