Answer:

Option B, Cladistics

Explanation:

In a biological classification system, organisms are grouped into different groups based on the similarity of physical (as per traditional classification systems) and genetic characteristics (as per modern classification systems).

Whittaker has grouped the organisms into five kingdoms - Monera, Protista, Fungi, Plantae and Animalia based on their cellular structure, reproduction, feeding pattern and many other physical characteristics.

However, Linnaeus’s classification group organisms into eight texas which are as follows -domain, kingdom, phylum, class, order, family, genus, and species.

However, Cladistics involves development of cladograms which are more or less similar to phylogenetic trees. Caldograms group organism based on the shared ancestry and descendants at each clade (group of organism also including ancestor species)

Hence, option B is correct

How do convection currents in the atmosphere form?

victus00 [196]

Answer:

B. Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down.

Explanation:

The options D and A can be eliminated because when a gas expands without gaining additional mass, it will become less dense; when a gas contracts without losing mass, it becomes more dense. Therefore, these two options conflict with the idea of density and cannot be true.

Option B is superior to Option C because convection currents are typically portrayed as beginning with the rise of warm air, which displaces/is replaced by cooler, dense air from the upper atmosphere. While Option C is similar, it describes the opposite series of events.

An engineer is developing a new prosthetic leg to help patients who have lost limbs to walk. The engineer is focused on making t

Karo-lina-s [1.5K]

Answer:

the engineer needs to consider alternatives for all of the areas of the design process that are considered costs

Explanation:

In order to accomplish this, the engineer needs to consider alternatives for all of the areas of the design process that are considered costs. This includes materials, marketing, manufacturing, etc. Many times the material that is being used alone can skyrocket the cost of making a specific product. Therefore changing to a new material may lack some of the wanted benefits but will reduce the overall cost. Manufacturing techniques can also drastically reduce costs by simplifying the process you save on electricity costs and worker wages, while still outputting the same amount of product, which in term reduces the overall costs of the item.

A geneticist claims that four species of fruit flies should appear in the ratio

Gemiola [76]

There are sufficient evidences which are of 5% significance level to reject the claim.

<h3>What is chi-square test?</h3>

A statistical test used to compare observed results with expected results is referred to as the chi-square test.

According to the given scenario,

Ratio = 1:3:3:9
Sample size = 2000
Samples = 110, 345, 360, and 1185

To calculate:

Evidence to make conclusion to the geneticist's claim.

Total fruits = 1 + 3 + 3 + 9 = 16

As per the expected number of fruit flies

Each species = 1/16(2000) = 125.3/16(2000) = 375.3/16(2000) = 375.9/16(2000)

Each species = 1125

According to Chi-Square test -

$X^{2} =\epsilon\frac{(O_{i}-E_{i})^{2} }{E_{i}}$

$X^{2}$ = ( 110 - 125)²/125 + ( 345 - 375)²/375 + ( 360 - 375)²/375 + ( 1185 - 1125)²/1125

$X^{2}$ = (15)²/125 + (30)²/375 + (15)²/375 + (60)²/1125

$X^{2}$ = 8

with df = 4 - 1 = 3, and P( x² > 8) = 0.0460.

Thus, with a P-value, it is small, indicates 5% significance level to reject the claim.

Which optical phenomena are formed by water droplets?

maw [93]

One of the most common and well known atmospheric optics, the rainbow is formed when sunlight is refracted and reflected by water. A collection of droplets in the atmosphere — whether from rain, a waterfall, a sprinkler, etc. — disperses the entire visible light spectrum at an angle, resulting in the circular shape.
