Effects of ecto-parasites of cattle​

Biology
1 answer:
erik [133]3 years ago
6 0
Data have shown significant differences in nitrogen retention, blood cortisol concentrations, vital signs, water con- sumption, and urine production. Implications are that total energy balance is altered when an animal is exposed to ectoparasite infestations, thereby resulting in decreased productivity.

Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and some types of beetles. This
docker41 [41]

Answer:

Luciferase transforms luciferin into oxyluciferin while consuming ATP and O₂, and causes the emission of light.  

<em>luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light</em>

Explanation:

Fireflies are organisms that emit cold light by the process of bioluminescence. It is a chemical reaction of male individuals to attract the females that also respond by emitting light.

Luciferin is the molecule responsible for light emission. The chemical reaction involves the luciferin molecule, ATP molecule, enzyme luciferase, and oxygen molecule. Luciferin, the responsible molecule for light emission, is transformed into oxyluciferin by the enzyme luciferase. The enzyme consumes oxygen and ATP, which is the principal source of energy in living beings. Finally, a light of about 560 nm is released.

luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light

Almost the entire amount of energy involved in the reaction turns into luminous energy. ATP used for this light production process comes from the photosite´s mitochondrial electronic chain, responsible for the organism´s energy production.

Photosites are the cells responsible for light production, and many of their mitochondria are placed near the plasmatic membrane to catch oxygen.

Oxygen gets in the organisms through the lantern trachea. During the respiration process, photosites consume oxygen. Mitochondria placed in the cell periphery near the cell membrane catch the oxygen molecules and produce ATP. ATP produced by oxidative phosphorylation is involved in the production of oxyluciferin, turning into AMP.

Posteriorly, the oxyluciferin molecule is recycled back to luciferin. This process shows how chemical energy turns into luminous energy.

Our brain has an amazing ability to adapt to changed inputs and to brain damage. We call this ability _____
Serhud [2]

The question is incomplete as it does not have the options which are-

a) plasticity.

b) lateralization.

c) pruning.

d) myelination.

Answer:

a) plasticity.

Explanation:

Neuroplasticity is the ability of the mind to the adapt which involves the physiological responses in the brain. This ability of the brain arises due to the fact that the brain continually reorganizes the neuronal connection from the uterus to the death which allows us to learn and experience various things with the same capacity of the mine.

The changes in the physiology of the brain due to neuroplasticity allows to survive in different conditions, learn new thing and experience new events which show the effect on the behaviour of the person.

Thus, a) plasticity is the correct answer.
