What is the main source(s) of energy for all living things?
Answer:
The sun
Explanation:
All living things get energy from different sources (a cow gets it from grass, dog gets it from meat), but eventually, most energy on Earth comes from the Sun. Plants use it to perform photosynthesis, other organisms eat plants, and so on!
Which pair of elements in the diagram is most likely to form a covalent bond?
Answer:
This question is incomplete
Explanation:
This question is incomplete. A covalent bond is a bond that involves the sharing of valence electrons (shared pair) by two atoms of the same/different elements/compounds. The electrons (valence) that are involved in covalent bonding are not the ones in pairs (lone pairs) on the outermost shell of the atom. For example, the single electron on a hydrogen atom is shared with another hydrogen to form hydrogen gas (H₂).
Another example is when the two individual/unpaired electrons on the outermost shell of an oxygen atom binds with two other unpaired electrons on the outermost shell of another oxygen atom.
Another example is when two different electrons from two hydrogen atom binds singly with the two unpaired electrons on the outermost shell of an oxygen atom to form water.
The diagram in the attachment provides illustration on the examples given.
Which types of native organisms do feral hogs most likely compete with for food sources?
Answer:
Here...
Explanation:
The feral hogs are most likely to compete with Herbivore and Carnivor for food sources. Option C is correct.
Herbivore:It is a type of food habit or nature in which an animal only eats plant or plants derived products.
For example Deer, Cows, etc.
Carnivorous:It is a type of food habit or nature in which an animal only eats other animal or animal-derived food.
For example- Lion, tiger, etc.
Since, feral hogs are omnivores who can eat both small animals and plants,
Therefore, the feral hogs are most likely to compete with Herbivore and Carnivor for food sources.

Carmen has a sample of matter. It is clear and smells sour. The sample is also thick but it flows when poured. Which is the best conclusion about Carmen's sample?
Answer:
liquid
Explanation:
In the given context, the sample as collected by Carmen is clear and the sample has a sour smell. It is also mentioned that the sample is thick sample and when the sample is poured on a surface it begins to flow.
Such a sample would be a liquid sample because anything that flows is a liquid. The liquid sample has a high viscosity since it is thick.
Answer:liquid

Which structure represents the cytosol within the cell
Answer:
In the eukaryotic cell, the cytosol is surrounded by the cell membrane and is part of the cytoplasm, which also comprises the mitochondria, plastids, and other organelles (but not their internal fluids and structures); the cell nucleus is separate. The cytosol is thus a liquid matrix around the organelles.

How many electrons are found in a C and O2-, respectively?
Answer:
For example: O2- indicates an ion of oxygen having two extra electrons. I.e., since an oxygen atom normally has 8 protons and 8 electrons, this ion has 10 electrons (-10 charge) and 8 protons (+8 charge) giving it a charge of -2 (-10 + 8 = -2).
Carbon has a total of six electrons and there are a total of ten electrons in the oxygen ion.
What we can easily find in common with carbon and oxygen atom is the fact that the both of them have two shells. We can also refer to these shells as energy levels.
In both atoms, the first shell contains only two electrons. For carbon, the second shell contains four electrons while the second shell of oxygen ion contains eight electrons.
Hence, Oxygen ion has two electrons in the first shell and eight electrons in the second shell(total of ten electrons) while carbon has two electrons in the first shell and four electrons in the second shell (a total of six electrons).
The electronic configuration of carbon is: 1s2, 2s2, 2p2
The electronic configuration of oxygen ion is: 1s2, 2s2, 2p6

Wich tools are appropriate to determine the densety of an irregular-shaped object ?
Answer:
The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A graduated cylinder large enough to hold both the object and enough water to fully immerse it is the best tool for this job.
Which substance is composed of only one type of atom? A: water B: sugar C: salt D: gold
Answer:
Gold
Explanation:
water = H2O(3 atoms)
Sugar = C12H22O11 (45 atoms)
Salt = NaCl ( 2 atoms)
Gold = Au ( 1 atom)
A substance that is composed of only one type of atom is gold. Thus, the correct option for this question is D.
What is an atom?An atom may be defined as the smallest unit of any matter that has the ability to form a chemical element. An atom may also be characterized as a particle of matter that uniquely illustrates a chemical element.
Water is composed of two atoms which are hydrogen and oxygen. Its chemical formula is [tex]H_20.[/tex] Sugar is a complex compound that consists of atoms of Carbon, hydrogen, and oxygen. Its chemical formula is [tex]C_6H_1_2O_6.[/tex] Salt typically consists of atoms of sodium and chlorine. Its chemical formula is NaCl.

7. A square chunk of plastic has a length of 5 cm, width of 5 cm and height of 5 cm. It has a mass of 200 g. What is its density?
Answer:
[tex]d=1.6\ g/cm^3[/tex]
Explanation:
Given that,
The dimension of a square chunk of plastic is 5 cm × 5 cm × 5 cm
Mass, m = 200 g
We need to find its density
Density = mass/volume
It will form a cube. It volume = side³
So,
[tex]d=\dfrac{200\ g}{5^3\ cm^3}\\\\d=1.6\ g/cm^3[/tex]
Hence density is [tex]1.6\ g/cm^3[/tex]

The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} [/tex]
From the question
mass = 420 g
density = 10.5 g/cm³
The volume is
[tex]volume = \frac{420}{10.5} \\ [/tex]

Decide which element probably forms a compound with oxygen that has a chemical formula most and least similar to the chemical formula of the compound formed by oxygen and cesium.
Answer:
Most similar ----- Lithium
Least similar ---- Nitrogen
Explanation:
Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as [tex]Cs_2O[/tex].
The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound [tex]Li_2O[/tex] with the oxygen
The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17 to form an [tex]NO_2[/tex] with oxygen.

A car accelerates from 0 to 72 km/hour in 6.0 seconds. What is the car's acceleration?
The acceleration of the car is equal to 3.33 m/s² with a velocity of 72 Km/hr.
What is acceleration?Acceleration can be demonstrated as the rate of change of velocity over time. The acceleration can be explained as vector quantity due to both magnitude and direction. Acceleration is defined as the 2nd derivative of the position of the object w.r.t. time.
According to Newton's 2nd law of motion, the force exerted is equal to the mass times of acceleration of an object.
a = F/m
or, a = dv/dt
Given, the final velocity of the car, v = 72 Km/hr
v = 72 × 1000/3600 m/s
v = 20 m/s
The time is taken by car to travel, t = 20 s
The acceleration of the car, a = (20 - 0)/(6 - 0)
a = 3.33 m/s²
Therefore, the acceleration of the car is 3.33 m/s².
