Modern humans have traits a high vertical forehead, a round and tall skull, and small browridges

The lighter skeletons of modern humans can be used to identify them anatomically from ancient humans. Modern humans have extraordinarily large brains, which vary in size from population to population and between males and females. The average size of these brains is approximately 1300 cubic centimetres.

Many of the physical and behavioural traits that modern humans have evolved share some similarities with other early human species, though not to the same extent. Modern humans were able to connect with their environment and one another in novel and unusual ways thanks to their complex minds. Our predecessors were better able to survive as the environment got more unpredictable thanks to larger brains.

Note that using the discrete distributions, it is found that the mean and standard deviation are given by: μ=5.28 and σ=1.67 (Option C)

A discrete distribution has data that can only take on particular values, such as integers. A continuous distribution is one in which data can have any value within a certain range (which may be infinite).

= 2.98

Var[tex]_{w}[/tex] (X) = 0.05 (0-2.98)² + 0.06 (1-2.98)² + 0.18(2-2.98)² + 0.35 (3-2.98)² + 0.3(4-2.98)² + 0.05 (5-2.98)² + 0.01 (6-2.98)²

= 1.4596

For Grubs:

E[tex]_{g}[/tex] (X) = 0.05(0) + 0.21(1) + 0.27(2) + 0.38(3) + 0.05(4) + 0.03(5) + 0.01 (6)

Var[tex]_{g}[/tex] (X) = 0.05 (0-2.3)² + 0.21(1-2.3)² + 0.27(2-2.3)² + 0.38(3 - 2.3)² + 0.05(4-2.3)² + 0.03(5-2.3)² + 0.01 (6-2.3)²

= 1.33

The sum, therefore, is given as:

E (X) = E[tex]_{w}[/tex] (X) + E[tex]_{g}[/tex] (X)

= 2.98 + 2.3

μ = 5.28

σ = √ (Var[tex]_{w}[/tex] + (Var[tex]_{g}[/tex] (X)

= √ (1.4596 + 1.33)

= √2.7896

= 1.67020956769

Carbon dioxide is a crucial greenhouse gas that helps keep heat in our atmosphere. Without it, our planet would be too cold to support life. But other aspects of Earth's climate are being impacted by an increase in average global temperatures spurred on by growing CO2 levels in our atmosphere.

Carbon dioxide is the source of carbon, the fundamental component of all life. Just as plants require carbon dioxide to thrive, animals eat plants to obtain the carbon they require to survive.

When incoming solar radiation is reflected back to space near the earth's surface, the atmosphere's carbon dioxide absorbs and stores the energy. The earth's surface would be cooler than it is now if there were no carbon dioxide because there would be no solar energy absorption.

Limestone is an example of sedimentary rock. It forms when ocean water evaporates and leaves calcium carbonate behind.

One of the most prevalent categories of chemical rocks is limestone. When calcium and bicarbonate ions erode from the remains of shells, coral, crustaceans, and mollusks in the water, they form limestone. These structures are gradually broken down by wave action into calcite and other calcium carbonate-based minerals, which build up in the ocean's water. These solutes can precipitate to form sediments rich in calcium carbonate as they are transported from the deep ocean environment to shallow areas like lagoons and tidal pools. For instance, calcium carbonate can precipitate in lagoons to form ooids, which are spherical nodules that cling together to form oolitic limestone, or limestone that has the shape of an egg.

Option A disruptive is the correct answer. This pattern of selection is disruptive because it favours the two extremes of a phenotypic characteristic, which results in sexual dimorphism.

Sexual dimorphism is the systematic shape difference between individuals of different sexes within the same species. For instance, the male in some species, such as many animals, is bigger than the female. The female of some species, like some spiders, is larger than the male. This sexual dimorphism has been noted in early development studies, childhood, adolescence, and maturity. On average, males' total brain size is around 8%–15% greater than females' (uncorrected for body size).

As a result, we can conclude that Option A disruptive is the best choice. Sexual dimorphism results from selection toward the two extremes of a phenotypic characteristic, hence this pattern of selection is disruptive.

Answer:

Plate tectonics is the theory that Earth's outer layer is composed of a number of large, rigid plates that move relative to one another. The movement of these plates is responsible for the creation of landforms and the shaping of Earth's surface over time.

There is a lot of evidence for the movement of these plates. For example, the distribution of earthquakes and volcanoes around the world is consistent with the movement of plates. In addition, the way that the rocks on the Earth's surface are arranged and the way that they have been deformed over time also provide evidence for the movement of plates.

There are three main types of plate boundaries: convergent boundaries, where two plates are moving toward each other; divergent boundaries, where two plates are moving away from each other; and transform boundaries, where two plates are sliding past each other.

At a convergent boundary, one plate will usually be pushed beneath the other, a process known as subduction. This can lead to the creation of mountain ranges, as well as the formation of volcanoes.

At a divergent boundary, the plates are moving away from each other, which can create gaps in the Earth's crust. This can result in the formation of new crust, as well as the creation of features such as rift valleys and mid-ocean ridges.

At a transform boundary, the plates are moving past each other, which can cause earthquakes and the formation of faults. This type of boundary is often associated with the creation of strike-slip faults, where the ground on either side of the fault is moving in opposite directions.

Overall, the theory of plate tectonics helps us to understand how the Earth's surface has changed over time and how landforms are created. The movement of the plates is a slow process, but it is ultimately responsible for the shaping of Earth's surface and the creation of the landforms that we see today.

Answer:

sequence of the RNA transcript produced from this part of the gene would be:

5' A A G C U U G G C U C 3'

Explanation:

The RNA transcript is produced by transcribing the DNA sequence into RNA using the enzyme RNA polymerase. During transcription, RNA polymerase reads the DNA sequence and uses it as a template to synthesize the complementary RNA sequence. Because RNA is single-stranded and DNA is double-stranded, the RNA transcript is complementary to the non-template strand of the DNA, not the template strand.

In the given DNA sequence, the non-template strand would be:

3' A A C G T T G G C T G 5'

The RNA transcript is produced by transcribing this non-template strand, so the resulting RNA sequence would be the complementary sequence:

5' A A G C U U G G C U C 3'

This RNA transcript would be the sequence of the RNA produced from the given DNA sequence.

Carbohydrates are made up of monosaccharides, which are simple sugars such as glucose. When two or more monosaccharides are joined together, they form a disaccharide or a polysaccharide. Polysaccharides are long chains of monosaccharides that are joined together by glycosidic bonds.

In order to break apart a carbohydrate made of 27 glucose monomers, you would need to hydrolyze the glycosidic bonds that hold the monomers together. Hydrolysis is the process of breaking a chemical bond by adding water molecules. For each glycosidic bond that you want to break, you would need to add one water molecule.

Since a carbohydrate made of 27 glucose monomers would have 26 glycosidic bonds (one less than the number of monomers), you would need to add 26 water molecules to break it apart. This is because each water molecule would be used to hydrolyze one of the 26 glycosidic bonds in the carbohydrate.

It's worth noting that the number of water molecules needed to break apart a carbohydrate would depend on the length of the carbohydrate and the type of glycosidic bonds it contains. For example, a carbohydrate with more monomers or with different types of glycosidic bonds might require more water molecules to be hydrolyzed.
