If 25 km3 of sand is deposited on a beach yearly and 28 km3 of sand is removed by wave action, the size of the beach would be decreasing, not increase.

First, there is a need to understand that the size of a beach is a function of the amount of sand deposited into it. The more the sand deposited, the more the beach would increase in size.

In this case, 25 km3 of sand is deposited annually but 28 km3 of sand is washed away by waves. The net amount of sand deposited can be calculated by subtracting the amount washed away by waves from the amount deposited. Thus

Net sand deposited = 25 - 28

                                     = -3 km3

Hence, the net amount of sand deposited annually is negative, meaning that the beach would decrease in size.

Answer:

Coral Reefs are filled with life with their extraordinary colors. As they supply other marine life with homes and hide out's , they are very fragile and delicate. Estuaries are wide and big, they can give homes to much more than the coral can but they can be dirtier than the coral reefs because it's a river unlike the coral reef's beautiful characteristics.

Answer:

Without friction, the equation of motion for a pendulum of length L is,

md2θdt2+mgsin(θ)L=0.

Or for small oscillations, (i.e., sin(θ)≈θ),

md2θdt2+mgθL=0.

Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to this differential equation is,

θ(t)=θ0cos(gL−−√t).

Frictional force adds an additional damping term into the equation of motion,

md2θdt2+λdθdt+mgθL=0,

where λ is a coefficient of kinetic friction.

Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to the damped differential equation is,

θ(t)=θ0e−12λmtcos((gL−λ24m2−−−−−−−−√)t).

(Note: If you would like to consider closed form solutions for large angles, I would recommend consulting the mathematics section. The solutions to that problem are called elliptic integrals of the first kind.)

Friction decreases the total time that a pendulum is in motion.

If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.

In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.

In the real world, the surface of objects cause friction which causes moving objects to stop.

Answer:

Both processes require energy cuz respiration produces energy

Explanation:

The statement that is not true is that both processes occur in mitochondria as photosynthesis happens in chloroplasts. So the correct option is B.

While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots respire slowly.

Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.

Plants produce glucose molecules during this process of cellular respiration by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.

Therefore the correct option is B.

Answer:

A. It loses an electron

Explanation:

An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

Answer

viruses kills cells and microorganisms can thrive where other species have been wiped out.

Explanation:

Microorganisms can flourish in areas where other species have been  off because viruses damage cells.

Viruses are the most prevalent creatures in the water, despite their seeming insignificance. One milliliter of coastal water that has been gathered from the ocean's surface contains up to 10 million.

In oxygen and hydrogen—which make up the water molecule—abound in large quantities. A typical salt that includes both sodium and chlorine is called sodium chloride. Many of the dissolved substances found in the ocean come from the crust of the Earth.

Through the process of photosynthesis, which involves the use of sunlight, nutrients, carbon dioxide, and water, phyto plankton produce oxygen and food for other organisms. the planet's seas, which cover 71% of it.

The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.

The system that contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products. The lymph system, which connects with the blood system, is often considered part of the circulatory system.

Answer:

Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division

Interphase is the part of time which mostly the cell utilises for its functionality.
