Answer: The combination of genes and environmental factors affects the growth of an organism.

Explanation:

Gene consists of DNA and it's heredity physical and functional unit. Genes play a vital role in a organisms growth. For example in humans, if one's parents are tall, there's a large tendency that such child will be tall and vice versa.

Environmental temperature also affects growth of living organisms. These include water soil pH, temperature, gender, chemicals etc. These all affects growth, it should be noted that proteins in living organisms can be damaged at a certain temperature which invariably affects the growth of such organism.

Also, the environment influences gene expressions as temperature, light, drugs, and chemicals, affects genes as they determine which ones will either be turned on or off which will further lead to how such organism grows.

What would the temperature of 0.734 moles of chlorine gas be at 1.83 atmospheres in a 10.2

lesya [120]

Answer: 310K

Explanation:

Given that:

Volume of Chlorine gas V = 10.2L

Temperature T = ?

Pressure P = 1.83 atm

Number of moles of chlorine gas N = 0.734 moles

Molar gas constant R is a constant with a value of 0.0821 atm L K-1 mol-1

Then, apply ideal gas equation

pV = nRT

1.83atm x 10.2L= 0.734 moles x 0.0821 atm L K-1 mol-1 x T

18.67atm L = 0.0603 atm L K-1 x T

T = (18.67atm L / 0.0603 atm L K-1)

T = 309.8K (Round up to 310K)

Thus, the temperature of the chlorine gas is 310 kelvin

mosquitoes get their food by sucking other animals blood, sometimes giving it disease. what type of symbiosis is this.

I believe that would be a parasitism because one organism benefits yet the other is harmed.

Chromium occurs naturally as four isotopes: 50cr with a mass of 49.9460 amu, 52cr with a mass of 51.9405 amu, 53cr with a mass o

bearhunter [10]

Hello!

The most stable isotope of Chromium is ⁵²Cr with a mass of 51,9405 amu.

We know that because of the information that we can find in the periodic table. Which information is that? The atomic weight of the element. Atomic weights are calculated taking into account the relative abundances of each isotope of the element. The isotope that is the most abundant one will influence more the atomic weight that is found in the periodic table.

For chromium, its atomic weight, that we can find on the periodic table, is 51,99 amu. The isotope weight that is nearest to this atomic weight is ⁵²Cr with a mass of 51,9405 amu, so that will be the most stable isotope.

Have a nice day!

Muriatic acid, an industrial grade of concentrated HCl, is used to clean masonry and cement. Its concentration is 11.7 M. For ro

Nata [24]

Answer:

$\boxed{\text{199 mL}}$

Explanation:

1. Calculate the moles of HCl

$n = \text{25.4 g} \times \dfrac{\text{1 mol}}{\text{36.46 g}} = \text{0.6967 mol}$

2. Calculate the volume of dilute HCl

$\begin{array}{rcl}\text{Molar concentration}& =& \dfrac{\text{moles}}{\text{litres}}\\\\3.50 & = & \dfrac{0.6967}{V}\\\\3.50V & = & 0.6967\\\\V & = & \dfrac{0.6967}{3.50}\\\\V & = & \text{0.199 L} =\textbf{199 mL}\end{array}\\\text{The volume of muriatic acid needed is }\boxed{\textbf{199 mL}}$
