Answer
Upper and Lower motor neurons, and Voluntary muscles.
Explanation:
Structurally,the motor neurons in the Brain are called the upper motor neurons.While the motor neurons in the spinal cord and the brain Nuclei are called the lower motor motor neurons.
Therefore, transmission of sensory impulses from the brain through the upper motor neuron are sent to the spinal cord through the lower motor neurons. These are eventually sent to the muscles(voluntary muscles) the effectors to bring response.
However, in ALS both the upper and lower motor neurons degenerate and die.Therefore transmission of action potential is impeded.Thus the voluntary muscles are made redundant with no sensory information and therefore they twitch (this is called fasciculations) and progressively undergo waste away.
As this progress the ability of the brain to initiate action potential for sensory information and its propagation is lost.
Therefore weakness of muscles and stiffness results,followed by complete loss of sensory transmission and inability of the individual to respond to sensory stimulus of walking, standing, eating, and breathing.Slurred and nasal speech,and muscles cramps are other symptoms
At advanced stage loss of life usually results from the respiratory failure.
it occurs mostly in the Caucasians and non-Hispanics between the age of 55-75,and common in males than females.It causes are blend of genetic and environmental factors.
Medication,therapy-physical and speech therapy are some means of treatments.

What did the comparative study on chytridiomycosis teach scientists studying white-nose syndrome in bats?Select one:a. Humans were responsible for the spread of chytridiomycosis, but not white-nose syndrome.b. A novel fungal infection could spread to colonies and cause dramatic population crashes, as seen in the comparative study.c. Chytridiomycosis affected only certain amphibians, so the comparative study could not teach the scientists anything useful.d. White-nose syndrome affects bats but does not cause death in organisms like chytridiomycosis does in amphibians.e. It was probably not a fungal infection affecting the bats and scientists needed to look elsewhere for a cause.
Answer:. A novel fungal infection could spread to colonies and cause dramatic population crashes, as seen in the comparative study
Explanation:
fungal diseases of wildlife, amphibian chytridiomycosis and bat white-nose syndrome are diseases in bat that have emerged rapidly and unexpectedly over the past several decades.
These diseases have lead to unprecedented local and global decrease in population of amphibian and bat species the infection colonize their territory and pose serious threats to biodiversity and ecosystem stability due to loss of many of them.

The fossil record is best at preserving visible changes in organisms through geologic time. This visible change is referred to as the evolutionary change.
The importance of fossil recordFossils are the remains or impressions of a historical organisms which are preserved as a mold or in rocks due to pressure.
Fossil records are information made concerning these historical organisms about:
the structure of the organisms, what they ate, what ate them, in what environment they lived, and the order in which they lived.When these rocks are studied, visible changes in organisms through geologic time are observed which is that simple life forms gradually evolved into more complex ones.
Therefore, evolutionary change. is that visible changes noticed in fossil records.

5. Count the number of hydrogen ions, oxygens,
and electrons on both sides of the equation
shown. Are they the same?
Answer:
1 hydrogen ion, 2 oxygen atoms and 4elctrons
The number of hydrogen, ions, Oxygen and electrons on both sides of the equations are:
Hydrogen = 4
Oxygen = 2
Electrons on both sides are the same.
What are atoms?Atoms are the smallest unit of matter. Particles inside atoms are referred to as subatomic particles. These can be found throughout the atom in various places. The particles are charged.
A neutron is neutral, a proton is positively charged, and an electron is a negatively charged particle that revolves around the nucleus. The nucleus contains protons and neutrons.
The reaction is when hydrogen attaches with oxygen, it forms water. The formula of water is [tex]\rm H_2O[/tex].
Therefore, Hydrogen = 4, Oxygen = 2 and there are the same numbers of electrons on both sides of the equation.

The neuronal serotonin reuptake transporter 5HTT1 is of great interest to the pharmaceutical sector. Your lab has recently isolated two compounds that bind directly to and act as inhibitors of serotonin uptake; these inhibitors have been named L2001 and L2002. Both L2001 and L2002 seem to reduce serotonin uptake 10-fold when added to cells individually. To characterize how L2001 works, your friend has discovered that L2001 does not affect the ability of 5HTT1 to bind serotonin, but instead seems to decrease the rate at which 5HTT1 is able to change its conformation. Another graduate student in the lab has been working on how L2002 affects 5HTT1 and has determined that L2002 acts in a manner consistent with its being a competitive inhibitor of 5HTT1 (i.e. competes with serotonin for its binding site). Given this information, would you predict that adding L2001 and L2002 together to cells would have a greater effect, a smaller effect, or no effect on 5HTT1 transport compared with the addition of only one of these inhibitors onto cells? Explain
Answer:
Adding L2001 and L2002 together to cells would have a greater effect on 5HTT1 transport compared with the addition of only one of these inhibitors onto cells

when neither allele contains instructions for a long tail
when at least one allele contains instructions for a long tail
Answer:
When both parents have a long tail :)
Explanation:
the short tail trait is now recessive so it cant happen on its own. The offspring will most likely have a long tail just like thae parents :)
Have an amazing day!!
Please rate and mark brainliest!!
Answer:
When at least one allele contains instructions for a long tail
Explanation:
Gregor Mendel discovered that an organism receives two forms of a gene called ALLELE for a particular trait. Each allele encodes or represent a different trait in that same gene. However, according to Mendel, one allele called DOMINANT allele is capable of masking the expression of the other allele, called RECESSIVE allele. This means that in a heterozygous state i.e. combination of the two different alleles, the dominant trait encoded by the dominant allele will always be expressed.

Answer:
Anabolism is the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy.
Examples of anabolism: bone growth and mineralization, and muscle mass build-up.
Catabolism: the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy.
Examples of Catabolism: glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.
Select choices that result from hydrogen bonding.

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Which of the following does not occur in an aquatic ecosystem as a result of nutrient loading?
a. acidification of the water
b. algae growth as a result of eutrophication
c. degraded quality of water for human and livestock consumption
d. improved water habitats for human recreation
Answer:
D
Explanation:
Overdosing on nutrients, especially nitrogen and phosphorus, can act as fertilizer and promote an excessive quantity of algae development in water bodies. Thus, option C is correct.
What is nutrient loading?Eutrophication, a process wherein water bodies get an excessive amount of inorganic nutrients, mainly N and P, promotes an excessive growth of plants and algae, is caused by nutrient enrichment in aquatic water bodies.
The calculation of annual loads involves multiplying daily flow by daily nutrient concentration and averaging throughout the course of the year.
Since samples were only taken once a week at most, daily concentration measurements are not available; therefore, daily concentration data must be entered to calculate loads.
Therefore, improved water habitats for human recreation.
