Explanation:

If Carl worked m less than 25, 25 - m would represent the amount of time Davis worked minus the difference in the amount of time that he and Carl worked, which would equal the amount of time Carl worked.

Answer:

The correct answer is B

Explanation:

A natural resource will always come from nature and it can be used for economic gain.

Yes, they can be used by people, but so can other resources, so the answer is not A.

Not all natural resources are unlimited, such as coal, are unlimited in quantity, so the answer is not C

Lastly, we do not leave natural resources untouched; we use them, so the answer is not D.

Answer:

Some researchers classify Australopithecines into gracile australopithecines and robust australopithecines, while others argue that differences are enough strong to classify robust australopithecines in their own genus called 'Paranthropus'. In my opinion, it seems reasonable to obtain more fossil data in order to support this division  

Explanation:

The term Australopithecines comes from the genus Australopithecus, which are the closest known relatives of our genus Homo, and arose around three (3) million years ago. Australopithecines can be classified into two major groups called gracile australopithecines and robust australopithecines. However, robust australopithecines have also been classified in their own genus, Paranthropus, in order to distinguish them from the gracile australopithecines. The major differences between gracile and robust species are associated with facial and cranial features. Paranthropus species had a large sagittal crest, enormous cheek teeth, robust jaws, and strong jaw muscles (suggesting they were herbivores that ate tough food). However, these main features may not be conclusive evidence that supports the separation of Paranthropus in its own clade, thereby in my opinion it should be reasonable to wait until more fossils are found in order ​to correctly classify Paranthropus species as a different group.

Answer:

This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis directly enters the glycolysis pathway as DHAP.

Answer:

Speech audiometry assesses your ability to hear and comprehend spoken words. ... They are also charted on an audiogram, which measures the decibel level, frequency and gravity of hearing loss.

Pure-tone audiometry only measures audibility thresholds, rather than other aspects of hearing such as sound localization and speech recognition. ... However, there are benefits to using pure-tone audiometry over other forms of hearing test, such as click auditory brainstem response pure tone audiometry, which only gives an indication of absolute perceptual thresholds of tonal sounds (peripheral function), whereas speech audiometry determines speech intelligibility and discrimination

Answer:

N = 187.55

Explanation:

Here you just need to replace the terms and clear the equation.

You already know that,

You let these animals leave and then you made another capture.

To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.  

Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch

So now, we need to replace terms

25 / N = 18 / 135

25 / N = 0.1333

N = 25 / 0.1333

N = 187.55

Answer:

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

Explanation:

I assume the plants with the yellow seeds are dominate (YY) , while the ones with green seeds are recessive (yy) (Since it would need to be recessive to be a different color than the dominate). The genes will always be heterozygous then, since it combines the genes from both parents.

1) If rTMS is deemed a success, it could be applied to other disorders by;

Option C; Increasing activity in the brain region involved.

2) The treatment most likely to help your aunt who has parkinson's is;

Option B; DBS

       1) rTMS is an acronym that means repetitive transcranial magnetic stimulation. The way it is used is that a coil is held above a part of the brain and recurring high magnetic pulses are targeted at specific brain structures.

This means that the activity of the region of the brain involved is stimulated.

Thus, when applied to other disorders, it could also be a success by increasing the activity in the brain region that is involved.

      2) Parkinson's disease is a neurological movement disorder. Now the best way to treat it is to transmit electrical impulses to a specific area of the brain that is responsible for the movement/motor symptoms that Parkinson's disease caused. This is done because electrical impulses interrupt the abnormal activity that occurs in the brain's circuitry which causes the symptoms of the Parkinson's' disease.

The treatment that goes through this process is called Deep Brain Simulation (DBS)

Answer:

Option C

Explanation:

Granite is composed of coarse-grained quartz and feldspars in varying proportions and due to the varying proportions of these two constituent materials, the texture of granite varies as shown in the image.

Thus, option C is correct

Options A and B  and D are incorrect because the constituent material of granite is not fixed. It  varies from from place to the  other.

Succession is the series of changes in an environment which results into making the environment more favorable for the organisms to live in. Pioneer species in the succession after fire will be lichens, fungi, and bacteria.

Ecological Succession is the process by which the species and habitat in an area changes over time. Succession is of two types depending upon the condition of the area which are Primary Succession and Secondary Succession. Primary succession is the succession in the area where no organism ever existed whereas secondary succession is the succession in the area where life has existed once but it has been destroyed due to catastrophic activity.

The pioneer species in this area are lichen, fungi, and bacteria. The establishment of organisms in a primary succession starts with the rocks or lava flow that has been hardened, then lichen goes on to the rocks and spews acid which dissolves the rock.

Big cats like tigers and other carnivores are often the to predators in an ecosystem. The trophic level do they most likely belong to is tertiary consumers. Thus, the correct option will be C.

Tertiary consumers can be referred to as the carnivore at the topmost level in a food chain which feeds on other carnivores in nature, which is an animal that feeds only on secondary consumers.

Tertiary consumers are those organisms that eats the secondary consumers (large predators) in nature. For example, owl species that eat snakes.

Answer:

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries."

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.
