The client has experienced a stroke, and her speech is now garbled. The client may have experienced damage to which of the following?
A. Brainstem
B. Medulla oblongata
C. Frontal lobe
D. Cerebellum

Answers

Answer:

C

Explanation:

A person with garbled speech may have experienced damage to the frontal lobe portion of the brain.

This is because the left portion of the frontal lobe of the brain is an area that has been touted to be responsible for the control of speech in humans. Research in the past has shown that damage to that region of the brain affects the formation of spontaneous speech as well as motor speech control.

Hence, garbled speech in someone that has experienced stroke can be attributed to damage to the frontal lobe.

What is a biological approach to determining when a mother and her conceptus become separate individuals?

Answers

Answer:

Electroencephalography.

Explanation:

Electroencephalography is used to measure brain activity in terms of electrical activity. It is done by attaching electrodes on the scalp, or sometimes by placing electrodes directly in the brain. Using electroencephalography can help determine when the fetus starts having its own brain activities, which means that it is now a separate entity distinguishable from its mother. Using electroencephalography to see brain waves can give us a deeper insight into the age old complicated issue of when a mother and her conceptus become separate individuals.

Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA

Answers

Answer:

Total ATP molecules produced = 94 molecules of ATP

Explanation:

Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.

Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and  FADH₂ and NADH molecules.

The overall yield of ATP from the various enzymatic steps is shown below:

Acyl-CoA dehydrodenase = 6 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 6 NADH

Isocitrate dehydrogenase = 7 NADH

α-Ketoglutarate dehydrogenase = 7 NADH  

Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)  

Succinate dehydrogenase = 7 FADH₂

Malate dehydrogenase = 7 NADH

Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,

Total ATP  from FADH₂ molecules = 13 * 1.5 = 19.5  

Total NADH molecules = 27 * 2.5 = 67.5

Total ATP molecules produced = 19.5 + 67.5 + 7  = 94

Total ATP molecules produced = 94 molecules of ATP

Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
a. cloning by complementation
b. direct sequencing of the mutant genome
c. PCR of the gene and transformation of an organism
d. cloning using a specific cloning vector

Answers

Answer:

Option a (cloning by complementation) `would be the correct choice.

Explanation:

In species containing extremely efficient transforming techniques as well as comparatively small genomes, cloning by rearrangement testing is performed to clone gene products mostly by a mutated gene as the rearrangement test was being used to detect mutations.This strategy for cloning through mechanism begins with identifying another yeast mutant that affects something like a plasmid representing a cloned genetic material.

The other options in question aren't relevant to the particular circumstance. Therefore the answer to the above seems to be the right one.

How does your body know when cells are missing

Answers

Answer:

Receptors provide information to nervous system about missing cells.

Explanation:

Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.

The body knows cells are missing as a result of the receptors sending

to the central nervous system.

The human body consists of cells which have neurons. These neurons are

responsible for the passage of messages and information to other parts of

the body.

When a cell is missing from the body, signals are passed to the central

nervous system which consists of the brain and spinal cord and they then

relay impulses which helps to fix the issue so as to ensure optimal

functioning of the body.

D. matter from the Sun is recycled after many years
by consumers, such as a Bachman's sparrow.

Answers

Answer:

There is no food web attached to this question but it can be answered because matter flows uniformly through trophic levels in all food webs.

The correct answer is;

A. matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.

Explanation:

A food web is an interconnected series of food chain showing how organisms feed on one another to obtain energy. A food web always start with a unique set of autotrophic organisms i.e. capable of producing their own food called PRODUCERS. Producers such as the cutleaf daisy in this question create the organic matter via the process of photosynthesis, which gets transferred to organisms that feed on them called CONSUMERS e.g green lynx spider

Consumers are heterotrophic i.e rely on other organisms for source of energy. As they feed on other organisms and get fed on, the matter gets transferred until the last consumer dies. The dead matter in the dead organism gets decomposed by organisms called decomposers e.g fungi and it gets recycled back into the soil as nutrients for use by plants.

Therefore, dead matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.

Explanation:

Answer:

The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.

When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.

A. There will be no difference as compared to an area that has saprotrophs and detritivores. •

B. There would be nothing left, it will have completely decomposed. •

C. The body would remain, and be just as it was when it died except for weathering. •

D. The body would be decomposing at about half the normal speed.

The correct option is C.

The body would remain, and be just as it was when it died except for weathering.

Explanation:

"If an organism were to die in an environment that had no saprotrophs or detritivores, The body would remain, and be just as it was when it died except for weathering because detrivores and feed on organic matter and excrete the nutrients, without detrivores and saprotroph the the organic matter in the dead organisms will still remain the same.

Detrivores are organisms that feed on dead organic matter and releasing nutrients to the ecosystem through it's wastes.

Saprotroph are decomposers that survive on or in dead organic matter secreting enzymes and releasing nutrients to the ecosystem. Examples is fungi.

Without detrivore and and saprotroph the dead organisms will remain the same except from weathering be side weathering is carried out through the activities of air, water or some agents.

Homeostasis is the biological process by which living organisms maintain a stable internal environmetal condition despite changes in their external environment. Homeostasis is an important phenomenon for the optimal functioning of any living organism.

A vivid example of homeostatic process is the regulation of temperature in humans or some animals. Self-r regulating mechanisms help keep their temperature at a stable state irrespective of temperature changes in the external environment i.e. hot or cold external conditions. The steady state of internal temperature is very important for some physiological processes in living systems.
