Answer:
Phenotype
Explanation:
The observable physical characteristics of an organism, as determined by both genetic makeup and environmental influences.
The question is asking about the observable physical characteristics of organisms.
We can eliminate options B and C because they don't make much sense. An organelle is a structure in a cell which conducts cellular functions, and the morphology of an organism is basically the anatomy and physiology of the organism, which isn't quite what we're looking for.
Keeping this in mind, here is some information on prefixes:
geno - relating to genes
pheno - relating to what's observable
The second one sounds a lot like what we're looking for, and just in case, the definition of phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Therefore your answer is: A. phenotypes

a sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. the density of gold is
Answer:
19.3 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 96.5 g
volume = 5 cm³
We have
[tex]density = \frac{96.5}{5} \\ = 19.3[/tex]
We have the final answer as
19.3 g/cm³Hope this helps you

. Which situation will result in lower average kinetic energy? a) 100 people go swimming into a NYC public pool b) 100 people go swimming at Coney Island beach
Answer:
I think it would be the beach because all the waves and such but in a pool with more people there is a tight space so they cant move around as much and as freely. But this could be a trickster question but I would choose the beach.

When you use a simple machine to do work, ________.
A
distance increases and force decreases
B
distance and force both increase
C
distance and force both decrease
D
distance decreases and force increases
Answer:
distance decreases and force increases
Explanation:
Simple machine means less power Hence it will require more force.Hence distance will decrease with respect to force and force will decreaseWhen we use a simple machine to do work, the distance decreases, the force increases. Hence, option D is correct. Because, these parameters are in inverse proportion.
What is force?Force is an external agent acting on a body to change its motion. There are various kinds of force such as frictional force, magnetic force, gravitational force etc.
Work done is the effectiveness of the machine to use the force to make the maximum displacement. Work done is the product of force and distance.
W = F.ds
As per this relation, the force acting on large distance makes greater work done. However,
F = W/ds.
Hence, as the distance increases, the force is decreasing. Therefore, option D is correct.

why is polystyrene soluble in acetone and not water
Polystyrene and acetone are not soluble in water because they are non-polar substances.
A polar substance is a substance that has opposite charges on two ends of the molecule. In polar molecules, a dipole moment exists in the molecule and accounts for its interaction with water.
Water is a polar solvent. It can only dissolve polar molecules. Since polystyrene and acetone are both non-polar substances, polystyrene dissolves in acetone and not in water.
This agrees with the principle in chemistry that like dissolves like.

Which of the three objects has the greatest density? Why? (GOLD BARS/GOLD COINS/GOLD CHAIN)
Answer:
They all have the same density
Explanation:
Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.
It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is [tex]19 \frac{g}{cm^3}[/tex].

An atom has 7 protons, 8 electrons, and 7 neutrons. What is the charge of the
atom and what type of ion is it?
Answer: An atom containing 7 protons, 8 neutrons, and 7 electrons is charge-neutral.
Explanation:
An atom is composed of protons (positively charged), neutrons (no charge) and electrons (negatively charged). The excess or defect of electrons in relation to protons determines the charge of an atom.
The atom described is an anion with -1 charge as it has one extra electron than protons.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

feet) you would weigh
A. more than in San Diego
B. less than in San Diego
C. the same as in San Diego
Answer: b
Explanation:
It will weigh less than in San Diego. So, the correct option is (B).
What is Elevation?The elevation of a geographic location is defined as its height above or below a fixed reference point known as a geoid which is a mathematical model of the Earth's sea level as an equipotential gravitational surface.
Height is defined as the vertical distance of a point on a horizontal surface while Elevation is the height of a point above (or below) sea level.
As the Elevation is higher, the weight will be less, whereas if the Elevation is less, then the weight will be more. For example, the elevation in San Diego is 15 feet, so the weight is 115 pounds, while the elevation in Denver, Colorado, is 5,280 feet, so the weight would be less than 115 pounds.
Thus, it will weigh less than in San Diego. So, the correct option is (B).

A dump truck, a sports car, and a bicycle are traveling at the same velocity. Which is true?
A The bicycle has the least kinetic energy.
B More information is needed to compare their kinetic energy.
C They all have the same kinetic energy.
D The sports car has the most kinetic energy.
Answer:
a
Explanation:
The object with greater mass is having greater kinetic energy. Here, all the objects has the same velocity therefore, the bicycle is having least kinetic energy.
What is kinetic energy?Kinetic energy is a form of energy generated by virtue of the motion of the object. The kinetic energy is related to the mass and velocity of the body by the expression below:
KE = 1/2 mv².
As per this equation, kinetic energy increases with an increase in mass or/ and velocity. The substance with greater mass is possessing the greater kinetic energy.
A dump truck has greater mass than a car and bicycle. Thus, at the same velocity for all, the greater kinetic energy is for the truck and the least kinetic energy is for the bicycle having the least mass here. Thus, option A is true.
