Answer:

i think that it is A

Explanation:

the other ones did not make as much sense

A scientist who studies the genetic engineering of crops most likely attempting how more stable supply of crops be created. so, option A is correct.

Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating a new DNA sequence.

In order to fix genetic flaws and hence prevent or treat hereditary illnesses, gene therapy aims to change specific genes.

The goal of genetic engineering is to alter the genes to increase the organism's capabilities beyond what is typical.

The term "genetic engineering" originally applied to a number of methods for modifying or altering living things through their heredity and reproductive processes.

Thus, option A is correct.

Answer:

1/4 of the offspeing will have the red flowers

Answer:

The large relative distances between particles in a gas means that there is considerable empty space between the particles.

The assumption that particles in a gas are relatively far apart explains gas compressibility.

Compressibility is a measure of how much the volume of matter decreases under pressure.

Energy is released by a gas when it is compressed

Explanation:

The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.

Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.

Answer:

Thymus. This gland makes white blood cells called T-lymphocytes that fight infection and are crucial as a child's immune system develops

Answer:

See explanation

Explanation:

1 mole of a gas occupies 22.4 L

x moles occupies 16.8 L

x = 1 mole *  16.8 L/22.4 L

x = 0.75 moles

number of moles = mass/molar mass

mass =  number of moles  * molar mass

mass =  0.75 moles * 30.01 g/mol = 22.5075 g = 2.25 * 10^1 g

the coefficient of the scientific notation answer = 2.25

the exponent of the scientific notation answer = 1

significant figures are there in the answer = 6

the right most significant figure in the answer = 3

2.

number of moles = 12.5g/38g/mol = 0.3289 moles

1 mole occupies 22.4 L

0.3289 moles occupies 0.3289 moles * 22.4 L/1 mole

= 7.36736 L = 7.36736 * 10^0 L= 7.37 * 10^0 L

the coefficient of the scientific notation answer =7.37

the exponent of the scientific notation answer = 0

Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

This number of molecules is

Answer:

Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids.

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

Explanation:

According to the law of conservation of mass, matter can neither be created nor be destroyed. However, it can be transformed from one form into another. During chemical reactions, atoms or ions are exchanged between reactants to form products. Thus, all the stoichiometric calculations are based on law of conservation of mass.

During redox reactions, one species is oxidized and other species is reduced. This involves electron transfer.

The only way your calculations makes sense is you're trying to calculate how ... Next, I'll interpret "I found that AZ is at -258°C" as "I calculated AZ to be 260 degrees below 2°C".

Explanation:

The experimental error will be 8.95%

The formula  used for calculating the percentage error is expressed as:

[tex]\% error=\frac{|exp. \ value - actual \ value|}{actual \ value} \times 100[/tex]

Given the following parameters

Actual value = −273.15 degrees Celcius

Let the experimental value be 300 degrees Celcius (since we are not given)

[tex]\% error=\frac{|300 - 273.15|}{300} \times 100\\\% error=\frac{|26.85|}{300} \times 100\\\% error=8.95\%[/tex]

Hence the experimental error will be 8.95%
