Amal was on a picnic to Hatta with his parents and family friends. While playing, he collected some muddy water from the Wadi in his beaker, which he wanted to make pure and clean. A) What do you think will happen to the mud in his beaker if left overnight? B) What is this process called?

Answers

Answer 1

Answer:

See the answers below

Explanation:

A) The mud in Amal's beaker will settle down at the bottom of the muddy water if left overnight with clear water occupying the surface. This is because the particles of mud are insoluble in water and will settle down at the bottom of the muddy water if left undisturbed for a while.

B) The process is called sedimentation. The settled mud particles are referred to as the sediments and the clear water at the top can be decanted off to separate the sediment from the water.

In your own words, describe the role of the scientific method in scientific investigation.

Answers

The role of the scientific method would be to test your hypothesis

The scientific method serves as a structured framework for conducting scientific investigations.

How does the scientific method shape investigative processes?

The scientific method involves a series of steps, starting with observation and formulation of a research question. Researchers then formulate hypotheses, educated guesses about the outcomes of their experiments.

These hypotheses are tested through carefully designed experiments, allowing for the collection of empirical data. The collected data is then analyzed to draw meaningful conclusions. The scientific method promotes objectivity, consistency, and reproducibility in research, enabling scientists to build upon existing knowledge and refine their understanding of the natural world.

Sickle-cell anemia is caused by a mutation that changes the second nucleotide of the codon from GAG to GUG. This results in a change of the amino acid from glutamic acid to valine. If the mutation affected the third nucleotide of the codon and changed GAG to GAU then the amino acid would change from a glutamic acid to aspartic acid. Would you predict this change to have the same effect

Answers

Answer:

This change would be predicted to have less effect compared to the change of the amino acid from glutamic acid to valine.

Explanation:

A conservative mutation is a type of mutation that leads to the replacement of one amino acid by another with similar properties. Both glutamic acid and aspartic acid are similar in size and biochemical properties. These amino acids are acidic dicarboxylic acids (i.e., they contain two carboxyl groups or ―COOH). The side chains of both glutamic acid and aspartic acid are similar, with the exception that glutamic acid contains one additional methylene group in its side chain.

Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)


Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots

Answers

Answer:

a. The letters Na with one dot

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.

A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.

Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.

For example, the Lewis structure diagram for Sodium (Na) is •Na.

Na with 1 dot

How does latitude affect a climate zone?

A. Climate zones at high latitudes are cooler because they are closer to the equator.
B. Climate zones at high latitudes receive a lot of precipitation because they are farther C. from the equator.
D. Climate zones at low latitudes receive little precipitation because they are closer to the ocean.

Answers

None of the options is entirely correct about latitude and climate zone.

Latitude and climate zone

Latitude is one of the main factors that affect climate, along with elevation, ocean currents, and prevailing winds.

Generally, the farther away from the equator a location is, the colder its climate is. This is because the angle of the sun's rays hitting the Earth's surface is more oblique at higher latitudes, resulting in less heat being delivered per unit of surface area.

However, precipitation patterns are not solely determined by latitude. They are also affected by other factors such as prevailing winds, ocean currents, and topography. For example, areas located on the windward side of a mountain range tend to receive more precipitation than those on the leeward side, regardless of their latitude.

Therefore, while latitude is an important factor in determining climate zones, it does not fully determine precipitation patterns or temperature.

Some of the smallest cells in the human body are red blood cells. They make up nearly half the volume of blood. A typical red blood cell is 8 µm across. The largest artery that blood flows through is the aorta, which is about 20 mm (2 cm) across. How many red blood cells would fit side-by-side across the aorta? Show your working.

Answers

Answer:

[tex]$1.6 \times 10^{-3}$[/tex]

Explanation:

Given data :

Size of a typical red blood cells = 8 µm

                                                     = 0.0008 cm

The size of the largest artery through which the blood flows, known as aorta

                                                     = 20 mm

                                                     = 2 cm

Thus the number of the red blood cells that would fit side by side across the aorta would be =   2 cm x 0.0008 cm

                          =    [tex]$1.6 \times 10^{-3}$[/tex]

While you and your little cousin are walking through a natural history museum, she points out the skull of an australopithecine with a large crest on the top and asks you what its purpose was. How might you correctly sum up this complicated evolutionary trait for your little cousin

Answers

Answer:

The purpose of the crest was to provide a surface for masticatory muscle attachment or insertion.

Explanation:

This crest is called the sagittal crest. It is present in extinct hominids, such as Australopithecus and Paranthropus, and can also be found in living animals such as gorillas or lions and some reptiles.

The sagittal crest is a bony structure that crosses the hominids´ skull longitudinally, and it is so well-developed that it stands out notoriously.

This crest, like others in the skulls, provides an attachment surface for many muscles. In the particular case of the sagittal crest, it is believed to provide an insertion area to mastication muscles.

It seems that Australopithecus had a special diet composed of tough items. The hominid probably needed to strong bite while eating. The strong jow muscles gave them the possibility to bite but needed a wide area for insertion. The sagittal crest provided that wide surface. There was a direct relationship between the size of the crest and the muscle mass. The bigger the crest was, the more developed the muscle was.

It is believed that in living animals, such as gorillas, the development of the crest in males is for sexual selection and reproductive success. The bigger the crest is, the more attractive the male is, and the more chances to be selected by the female to mate it will have. Some hypothesize that the development of the crest in Australopithecus could also be related to sexual selection.
