I’m learning about heredity
1. How can environment influencers inherited traits
2. How many chromosomes do humans have? Explain where these chromosomes come from.
Answers
Answer:
1. (See explanation)
2. 46. 23 from the mother’s egg and 23 from the father’s sperm.
Explanation:
ok for number one I am not entirely sure, but I am pretty sure that light, chemicals and temperature can all affect which genes get turned on and off. I am not entirely sure if the question is asking about the environment influencing inherited traits in the form of natural selection tho? If that is something you’re seeing right now, it might be a possible answer. But honestly I am not completely sure.
2- Humans have 46 chromosomes half from their mom and half from their dad.

Which of the following happens to a molecule of an object when the object is cooled?
Answers
Answer: It loses kinetic energy.
The compound has the empirical formula of CH. Give some possible molecular formulas for this compound if you didn't know the molar mass.
Answers
Answer:
Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.
Explanation:
The result is the molecular formula

The density of mercury is 13.6 g/mL. What is the mass of 3,426 mL of mercury?
Answers
Answer:
m = 46593.6 g
Explanation:
Given data:
Mass of mercury = ?
Volume of mercury = 3426 mL
Density of mercury = 13.6 g/mL
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
13.6 g/mL = m/ 3426 mL
m = 13.6 g/mL × 3426 mL
m = 46593.6 g

What is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K?
Answers
Answer:
12.3
Explanation:
Trust
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 12.3L is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. There is no force of attraction between the particles.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of oxygen gas= 2.00 atm
V= volume of oxygen gas =?
n =number of moles of oxygen gas=1.00 mol
T =temperature of oxygen gas =300.0 K
R = Gas constant = 0.0821 L.atm/K.mol
Substituting all the given values, we get
2.00×V=1× 0.0821×300.0
On calculation we get
Volume=12.3L
Therefore, the volume of oxygen is 12.3L.

What does the nucleus of an atom do to its own electrons? To the electrons of a nearby atom?
Answers
An atom is made up of energy levels that contain electrons which are negatively charged and the nucleus which contains neutrons and protons that are negatively charge .
Due the positive charge of the nucleus of an atom, an atom always want to attract its electrons and keep them near it however it weakly attracts the other electrons of a nearby atom.
