what is the molar mass of the chemical FeCI3 ?
Explanation:
The molar mass of iron(III) chloride is 162.204 g/mol.
The molar mass of the chemical FeCI3 is 162.20 g/mol. Molar mass is the mass of one mole of a substance.
What is molar mass?The molar mass represents the mass of one mole of a substance. It is measured in grams, per mole (g/mol). The mole, which serves as a unit of measurement helps in counting the number of atoms, molecules or ions, in a substance.
In the case of FeCl3, we have one iron atom (Fe) and three chlorine atoms (Cl).
The atomic mass of iron is 55.845 g/mol while the atomic mass of chlorine is 35.453 g/mol.
Thus to calculate the mass of FeCl3 we add up the products of the masses and their respective quantities:
Molar mass of FeCl3 = (1 x 55.845 g/mol) + (3 x 35.453 g/mol) = 162.20 g/mol

Cellular respiration is the process by which organisms use chemical energy from food and oxygen molecules to power the basic life processes. Thus, the correct option is A.
What is Cellular respiration?
Cellular respiration is the process by which cells in living organisms break down sugar (carbohydrates) and turn it into energy in the form of ATP. This energy is later used to perform work at the cellular level. The purpose of cellular respiration is providing cells with the energy they need to function.
Cellular respiration is a series of chemical reactions to produce ATP. The main stages of cellular respiration include: glycolysis, pyruvate oxidation, citric acid cycle or Krebs cycle, and oxidative phosphorylation.
An example of cellular respiration in plants is the photosynthesis which is used to obtain the glucose needed for cellular respiration. This means that plants can use the light energy they acquire from the sun to yield glucose and oxygen. This glucose is converted to pyruvate by glycolysis.
Therefore, the correct option is A.

A piece of metal with a mass of 32.8 g is heated to 100.5°C and dropped into 138.2 g of water at 20.0°C. The final temperature of the system is 30.2°C. What is the specific heat capacity of the metal?
Answer:
Specific heat capacity of metal is 2.6 J/g°C.
Explanation:
Heat lost by metal = Heat gained by water
[tex]m_{m}[/tex][tex]c_{m}[/tex]ΔT = [tex]m_{w}[/tex][tex]c_{w}[/tex]ΔT
where: [tex]m_{m}[/tex] is the mass of metal, [tex]c_{m}[/tex] is the specific heat capacity of metal, ΔT is the change in temperature of metal and [tex]m_{w}[/tex] is the mass of water, [tex]c_{w}[/tex] is the specific capacity of water and ΔT is the change in temperature of water.
32.8 x [tex]c_{m}[/tex] x (100.5 - 30.2) = 138.2 x 4.2 x (30.2 - 20.0)
32.8 x [tex]c_{m}[/tex] x 70.3 = 138.2 x 4.2 x 10.2
[tex]c_{m}[/tex] x 2305.84 = 5920.488
[tex]c_{m}[/tex] = [tex]\frac{5920.488}{2305.84}[/tex]
= 2.56761
[tex]c_{m}[/tex] = 2.6 J/g°C
The specific heat capacity of the metal is 2.6 J/g°C.
The specific heat capacity of the metal is 2.6 J/g°C.
Calculation of specific heat capacity:We know that
Heat lost by metal = Heat gained by the water
So,
[tex]m_mc_m\Delta\ T = m_wc_w\Delta\ T[/tex]
Here
[tex]m_m[/tex] is the mass of metal,
[tex]c_m[/tex] is the specific heat capacity of metal,
ΔT is the change in temperature of metal
[tex]m_w[/tex] is the mass of water,
[tex]c_w[/tex] is the specific capacity of water
and ΔT is the change in temperature of water.
Now
32.8 x c_m x (100.5 - 30.2) = 138.2 x 4.2 x (30.2 - 20.0)
32.8 x c_m x 70.3 = 138.2 x 4.2 x 10.2
[tex]c_w[/tex] = 2.6 J/g°C

You are conducting a twin study to estimate the heritability of a particular trait and have found that monozygotic twins have a concordance of 75%. Using ONLY this information, does this trait show high, low, or unknown heritability? Write no more than two sentences to justify your conclusion, and/or specify how to use additional information to determine heritability. ITRE
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
Answer: C. Fermentation
Explanation: The yeast strain will do more fermentation because the cytochrome c protein is what gives the yeast energy and ATP. Without this gene, the yeast strain will need to find a different way to make energy, like fermentation.

HAPPY NEW YEARS !!! CAN SOMEONE PLEASEEEE HELP ME WITH THIS SCIENCE QUESTION I WILL MARK YOU BRAINLIEST !!!
Answer:
According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).
Explanation:
The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.
The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.
The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.
The other options are not correct because:
C and D. In developing countries such as Nigeria and Ethiopia, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape.
B. Italy, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.
