Answer: c

Explanation: makes sense

The Earth's outer core is mainly composed of the liquid metals such as iron and nickel. Thus, the correct option is C.

The outer core begins approximately in the range of 2,889 km or 1,795 miles beneath the Earth's surface at the core-mantle boundary of the Earth and ends at 5,150 km or 3,200 miles beneath the Earth's surface at the inner core boundary of the Earth.

The outer core of the Earth is mostly composed of liquid iron and nickel. The Nickel and Iron alloy of the outer core is very hot, between 4,500° and 5,500° Celsius temperature. The outer core of the Earth is mostly made up of iron and nickel elements. This alloy is often written as NiFe because it is a combination of their chemical element symbols.

Therefore, the correct option is C.

1.)___A__sugar=deoxyribose

2.)__A___double helix strands

3.)__A___thyamine

4.)__C___adenine

5.)__C___guanine

6.)__C___cytosine

7.)__B___sugar=ribose

8.)__B___single genes strand

9.)___B__uracil

10.)___C__genetic blueprint

Explanation:

Deoxyribose sugar is present only in the DNA molecule whereas in RNA molecule the sugar found is ribose sugar.  DNA molecule is generally found in a double-stranded helical form that consists of adenine, guanine, cytosine, and thymine bases.

In RNA molecule there is all bases present that found in DNA instead of thymine, RNA has uracil in place of thymine. Both nucleic acids are known as the genetic blueprint of organisms as they contain genetic codes or information.

Answer:

The cell membrane controls the substances that enter and exit the cell

Explanation:

The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.

The membrane is a semi-permeable barrier that lets some substances in and out, but not others.

Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

Answer:

Explanation:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.

Answer:

The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of polymers of amino acids. It is made up of long chains of fatty acids.

Explanation:

The biomolecules that make up this surface of leaves differ from other biomolecules by the fact that they are made up of long chains of fatty acids. Thus, the correct option is A.

Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.

The long chains of fatty acids typically consist of a hydrophobic arrangement that prevents the movement of water from one part to the other. This specific property of forming a water barrier is only present in fatty acids.

Due to this, the surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable, which means to prevent the migration of water.

Therefore, the correct option for this question is A.

Explanation:

Answer:

In this relationship , the role of wolves is  as Secondary Consumers .

Explanation:

A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.  

A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).

PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.

SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.  

In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are  producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .

Hence, the correct answer is  OPTION D.

Answer:

The correct model is D.

Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.

Explanation:

A water molecule is composed of one atom of oxygen and two atoms of hydrogen.

A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.

The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

A collection of stars, dust, and gas bound together by gravity is called galaxy.

A galaxy is a collection of stars, dust, and gas bound together by gravity. Galaxies vary in size and shape, and can contain anywhere from a few hundred million to trillions of stars. They also contain other celestial objects such as planets, asteroids, comets, and nebulas. The Milky Way, in which our solar system is a part of, is an example of a galaxy.

A universe is the entirety of everything that exists, including all matter, energy, space, and time, including all galaxies, stars, and all other forms of matter and energy.

A solar system is a group of celestial bodies that orbit around a star, including planets, moons, comets, and asteroids. The sun and all the objects that orbit it, including Earth, are part of the solar system.

A planet is a celestial body that orbits around a star, is spherical in shape and has cleared its orbit of other debris. They do not emit light and heat like stars do, but rather, reflect the light and heat of their host star.
