Identify and explain one potential issue with the monitoring approach of zebra mussels used in areas like Lake Tahoe.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

no problem

Answer:

There is no way of finding the volume of an irregular shape.

We cant find the volume of an irregular solid because we can never measure the volume of curves that are present in an irregularly shaped object. so we tend to place this irregular object in a beaker of water so that the volume of water displaced by it will actually show us the volume of object itself. And now we can conclude that water displacement is an effective way of measuring the volume of an irregular solid there is no way of finding the volume of an irregular shape.

Answer:

The particles movement increases.

Explanation:

This is because as the particles change from liquid to gaseous state, they acquire more energy due to latent heat of vapourization hence increased movement.

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.

Answer:

High coefficient of expansion

Explanation:

It is only mercury that is in liquid form at room temperature. It works on the principle of thermal expansion, it expands when heated and contracts when cooled. The very minute change can be notable by the use of mercury in the thermometer. So this property of the thermometer makes it suitable for measuring temperatures.

Answer:

C

Explanation:

What causes blood pressure?

C

To pump blood around the body, the heart contracts and then relaxes through the cardiac cycle. The cycle begins with the contraction of the two atria, which push blood into the ventricles. Then, the ventricles contract, which forces the blood out of the heart.

When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure.

When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.

Answer:

D. There are more than 100 naturally occurring elements that make up all matter.

Explanation:

All matter is made up of elements, which are substances that cannot be broken down into simpler substances by chemical means. There are more than 100 naturally occurring elements, each with its own unique properties and characteristics. These elements combine to form compounds, which are substances made up of two or more elements that are chemically combined in a specific ratio. For example, water is a compound made up of two hydrogen atoms and one oxygen atom. Atoms can bond with each other in various ways to form compounds, but they do not always bond to achieve a stable neutron-proton ratio. The stability of an atom or compound depends on a variety of factors, including the arrangement of its electrons and the nature of the chemical bonds it forms with other atoms.

Answer:

D. There are more than 100 naturally occurring elements that make up all matter.

Answer:

K2O

Explanation:

It carries the chemical formula K2O. Potassium cannot be found free because it is too reactive. It has valency +1 and combines readily with oxygen atoms forming K2O.

Answer:

d

Explanation:

a) Atom 1 has 35 protons and 45 neutrons, which means it is the element bromine (Br). Atom 2 has 12 protons and 12 neutrons, which means it is the element magnesium (Mg).

A metalloid is an element that acquires both metal and nonmetal properties. Metalloids have some characteristics of metals, such as being good conductors of electricity, while also having some nonmetallic properties such as being brittle and lacking the ability to be hammered into shape. They are located along the "staircase" on the periodic table, between the metals and nonmetals, and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids are important in various applications such as semiconductor industry, in which silicon is the most widely used metalloid for the production of computer chips and solar cells.

b) Bromine (Br) is a nonmetal and magnesium (Mg) is a metal.

c) Magnesium (Mg) is a metal and bromine (Br) is a nonmetal, so they would form an ionic bond.

d) The compound formed between magnesium (Mg) and bromine (Br) would be named magnesium bromide.

e) The formula for magnesium bromide is MgBr2, since magnesium (Mg) has a +2 charge and bromine (Br) has a -1 charge.

Answer: Mass, Volume, shape

Explanation: that’s the three basic properties of matter

The geocentric model represents the earth at the center of the universe. The model couldn't explain the backward and loop movement of the planets. Thus, option d is correct.

The geocentric model was an early cosmological theory given by Eudoxus and Aristotle that defined Earth at the center of the universe with planets and the Sun revolving around it. It stated about the circular path followed by the celestial bodies.

The people on the Earth do not feel the planet moving, and hence it was assumed that it was the center. The circle being perfect was considered to be the motion of the revolution.

The model cannot establish the backward and loop-like movement of planets like mars where they move ahead and a little back when revolving.

Therefore, option d. the backward movement of the planets did not support the geocentric model.
