Explanation:

Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.

Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)

Answer:

Guanine

Explanation:

C to G and A to T

In RNA, cytosine (C) forms a base pair with guanine (G).

This pairing is based on complementary base pairing rules, where cytosine always binds with guanine through three hydrogen bonds.

In RNA, as well as in DNA, the base pairs play a crucial role in the structure and function of genetic material.

The pairing between cytosine and guanine, along with adenine (A) pairing with uracil (U) in RNA (or thymine (T) in DNA), creates the double-stranded structure of nucleic acids.

These base pairs provide stability and ensure accurate replication and transcription of genetic information, contributing to the essential functions of RNA and DNA in various biological processes.

Explanation:

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

After an RNA (Ribonucleic Acid) molecule is transcribed from a eukaryotic gene, portions called introns are removed and the remaining exons are spliced together to produce an mRNA molecule with a continuous coding sequence.

Plant parts are flattened and at least some of the original plant material remains. Leaves are often preserved as compressions.

C. Is travelling on a curve in the road.

Explanation:  the two vehicles behind the truck is moving at a constant speed because there is no change in velocity. The truck is changing directions AND speed (Acceleration/Velocity).

The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound).

Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.

The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).

Therefore, The  pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.

Answer:

Sperm have a well-protected head and a motor to help them travel.

Explanation:

Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.

- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.

Answer:

All living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.

In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.

What is fusion?

Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.

Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.

Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.

Water as a constructive force: It is involved in the deposition of sediments. It transports rock fragments, soil, and other debris at a particular area. This process eventually causes them to accumulate and form land features. Water as a destructive force: It is involved in weathering and erosion.

Explanation:

(pls mark brainliest if u can)

:)

Water can be both a destructive and a constructive force.

• The forces, which form or create an existing landform are known as the constructive forces. While the force, which tears or lowers down the surface features of the Earth are known as the destructive forces.

• Water can be considered as the constructive force as it carries sediment down the river and with the river becoming shallow, the deposition of the sediments takes place giving rise to landforms called deltas.

• On the other hand, water can also be considered as a destructive force as it takes part in processes like erosion and weathering. It breaks down and wears away the rocks and land masses.

Thus, water can be both destructive and constructive.

Wolves from the same pack are all feeding on the same deer. What type of species. In this, the type of the species is intraspecific competition.

Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce.

Interspecific competition may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species.

Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area.
