Genes remove the environmental factors that affect the growth of an organism.
Genes remove the environmental factors that affect the growth of an organism.
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 is the mass in grams, if you have 8.42 x 10^18 atoms of Bromine
Answer:
84.2 grams
Explanation:
you have to multiply 8.42x10^18 to get the answer above
The number of the atom can be used to estimate the mass and moles of the substance by Avogadro's number. The mass of 8.42 x 10¹⁸ atoms of Bromine is equivalent to 0.0011 grams.
What is the mole concept?The mole concept has been the unit of the amount of estimating the mass of the substances with smaller entities. It uses the SI unit mol to measure the amount of mass. It also has been defined by 6.02214076 × 10²³ (Nₐ, Avogadro's number) elementary entities.
The molar mass of Bromine (Br) is 79.904 u and atoms are 8.42 x 10¹⁸.
Atoms to mass are converted as:
= ( 8.42 x 10¹⁸ atom ÷ 1 ) × ( 1 mole Br ÷ 6.02214076×10²³ ) × (79.904 gm Br ÷ 1 mol Br)
= (8.42 x 10¹⁸ × 79.904 gm) ÷ 6.02214076 × 10²³
= 6.727 × 10²⁰ ÷ 6.02214076 × 10²³
= 1.117 × 10⁻³ grams
Therefore, 0.0011 grams is the mass of bromine.

What % of all the atoms in the universe are hydrogen
Answer:
Over ninety percent of all the atoms in the Universe are hydrogen atoms.
Explanation:
Over ninety percent of all the atoms in the Universe are hydrogen atoms. By mass, hydrogen makes up about 75% of all matter in the Universe. Hydrogen atoms are also the smallest and lightest of all the atoms with only one electron and one proton in a common single hydrogen atom (called protium).
what are 3 examples of pairs of atoms with nonpolar covalent bonds?
Answer:
Carbon dioxide - CO.
Benzene - C6H.
Carbon tetrachloride - CCl.
Methane - CH.
Ethylene - C2H.
Explanation: Some examples of atoms with nonpolar convalent bonds. Hope this was found useful!!
Non polar covalent compounds have no net dipole moment due to charge separation. Some examples are, CO₂, H₂, N₂,O₂ etc.
What are covalent compounds?Covalent bonds are formed by the sharing electrons between atoms. Covalent bond is comparatively weaker than ionic bonds. Atoms of deficient number of electrons will combine by sharing their valence electrons and forms covalent bonds.
When one atom has more electronegativity, then the shared pair of electrons will attracted into the electronegative atom. This creates a charge separation and a dipole moment.
However, if the electronegative atoms are linear in geometry from the central less electronegative atom then the dipole moment cancel each other and the compound become non polar as in the case of CO₂.
All gases in molecular states are covalently bonded and are non polar such as H₂, N₂,O₂ etc.

Which ion is found in all acids
An acid is a chemical that, when added to water, releases hydrogen (H+) ions. The ion is found in all acids is H⁺ ion. Therefore, option B is correct.
What is an acid ?A Brnsted-Lowry acid or Lewis acid is a molecule or ion that has the ability to donate a proton or establish a covalent bond with an electron pair.
An acid is a chemical that, when added to water, releases hydrogen (H+) ions. A hydrogen ion is made up solely of a proton. The formulations for many acids may all be found to contain at least one H, such as hydrochloric acid.
The word "acid," which refers to the sour flavor and pungent odor of numerous acids, derives from the Latin word acidus, which meaning "sour." Examples: Because acetic acid and water are diluted, vinegar has a sour flavor.
Thus, option B is correct.

In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She asks the students to think about how the temperature of the water will affect the chemical reaction that occurs inside the glow stick once it is bent and starts to glow.
Which glow stick will be brighter once it is bent? Explain your answer.
Answer:
The glow stick in hot water will be brighter
Explanation:
The glow stick in hot water will be brighter than the glow stick in cold water because the heat from the hot water will cause the molecules in the glow stick to move faster. The faster the molecules move in the glow stick, the sooner and brighter the reaction will be. The cold water will cause molecules to move slowly and it will take longer for the reaction to occur, which will also make it less bright.
Answer:
The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster. The reaction happens faster, because increasing the temperature increases the rate of a chemical reaction.
