Answer:
Mutation
Explanation:
Mutation refers to the change in the structure of a gene. This change occurs when changes are made in the base/nucleotide sequence on a gene.
An example of such error made during DNA replication are incorrectly paired nucleotides or insertion/deletion of nucleotides during replication.
Define respiration in plants:
Define Transpiration in plants:
( Can’t be short has to at least be long or medium sized )
Answer:
Respiration in plants: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. ... As with photosynthesis, plants get oxygen from the air through the stomata.
Transpiration in plants: The water eventually is released to the atmosphere as vapour via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapour by leaves is known as transpiration.

What is an example of an organism that undergoes binary fission?
Unicellular organisms such as amoeba and leishmania undergo binary fission.
What is binary fission?Binary fission can be described as a form of asexual reproduction where an organism divides into two, each part having one copy of genetic material.
Binary fission can be described as a kind of asexual reproduction observed in prokaryotes and a few single-celled eukaryotes. In asexual reproduction, there is a separation of the parent cell into 2 new daughter cells. This process occurs with the division and duplication into two parts.
Binary fission is a primary of reproduction in prokaryotic organisms. Binary Fission happens without spindle apparatus formation in the cell. The single DNA molecule starts replication and attaches each copy to parts of the cell membrane.
Prokaryotes and eukaryotes such as euglena reproduce via binary fission. This process is rapid, and its speed varies in species. The time needed by bacteria to double the cells it has is called known as doubling time.

E. Particle emitted = gamma ray; protons gained = 0; Change in mass = 0
F. Particle emitted = alpha particle; Protons lost = 2; Change in mass = -4
Explanation:
Radioactivity is the spontaneous disintegration of nucleus of an atom resulting in emission of particles and radiation unyil a stable atomic nuclei is obtained. Substances that are exhibit radioactivity are known as radioactive substances and are usually isotopes of stable atoms.
The types of radiation emitted by a radioactive substances include alpha rays, beta rays, and gamma rays.
Alpha rays or particles are fast moving positively charged particles with a mass number of four and atomic number of two. Thus, each alpha particle is a helium nucleus.
Beta rays or particles are vary fast moving stream of electrons having a mass number of zero and a charge of -1.
Gamma rays are not particles but are electromagnetic waves similar to visible light and X-rays but with shorter wavelengths. They have no mass or charge.
An atom emitting alpha particles has its mass reducing by 4 units and its atomic number decreasing by 2.
An atom emitting beta particles as it decays has no change in mass but its atomic number increases by 1.

H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide
Answer:
Explanation:
Find the molar mass of H2SO4
2H = 2 * 1 = 2
S = 1 * 32 =32
O4 = 4*16 = 64
total 98
Find the number of mols in 71.5 grams
mols = given mass / molar mass.
given mass = 71.5
molar mass = 98
mols = 71.5/98
mols = 0.7296 mols of H2SO4
Find the moles of H2O
From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O
mols water = 2 * 0.7296
mols water = 1.4592
That's as far as I can take you. I have to know a great deal more to get the volume of H2O

describe the process to determine the limiting reactant in the example listed below:
Given 3.4 grams of x element with a molar mass of 24 g/mol and 4.2 grams of y element with a molar mass of 35 g/mol. How much of compound xy2 can be generated?
x + 2y -> xy2
The amount of the compound [tex]XY_2[/tex] that can be generated would be 11.28 grams
Stoichiometric calculationFrom the equation of the reaction, the mole ratio of X and Y is 1:1.
Mole of 3.5 grams of X = 3.4/24 = 0.1417 moles
Mole of 4.2 grams of Y = 4.2/35 = 0.12 moles
Thus, Y is the limiting reactant because it is present in a lower amount than needed.
Mole ratio of Y and [tex]XY_2[/tex] = 1:1
Equivalent mole of [tex]XY_2[/tex] = 0.12 moles
Molar mass of [tex]XY_2[/tex] = 24 + (35x2) = 94 g/mol
Mass of 0.12 moles of [tex]XY_2[/tex] = 0.12 x 94 = 11.28 grams

Se midió el pH de una muestra del agua de lluvia en la ciudad de México, y se obtuvo un valor de 3.5 Calcula la [H+] en dicha muestra.
Answer:
[tex][H^+]=3.16x10^{-4}M[/tex]
Explanation:
¡Hola!
En este caso, dado que el pH de una solución se entiende como el potencial de los iones hidrógeno en la misma, es posible recordar la ecuación que se usa para calcularlo:
[tex]pH=-log([H^+])[/tex]
De este modo, al conocer el pH, se resuelve para la concentración de iones hidrógeno como se muestra a continuación:
[tex][H^+]=10^{-pH}[/tex]
Así, reemplazamos el pH para obtener:
[tex][H^+]=10^{-3.5}=3.16x10^{-4}M[/tex]

A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations.
Answer:
The population of the long-legged birds decreases.
Explanation:
The population of the short-legged birds increases whereas the population of long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.
Why might changes to an environment cause an organism’s population to decrease?
A gas sample at 40° C occupies a volume of 3.22 L. If the temperature is raised to 55°C, what will the volume be, assuming the pressure remains constant?
Answer:
3.374L
Explanation:
According to Charle's Law:
V1/T1=V2/T2 (At constant pressure and moles)
where V=Volume and T=Temperature.
The temperature must be in kelvin.
K=C°+273
T1=40+273=313K
T2=55+273=328K
By applying the formula, we get:
3.22/313=V2/328
V2=(3.22*328)/313
V2=3.374L
Select all that identify a covalent bond.

Heres the best help i can give you There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals

What volume of 2.0 M hydrochloric acid solution will be consumed when it reacts with 5 grams of magnesium to form magnesium chloride and hydrogen gas?
2HCl + Mg -> MgCl2 + H2
Answer:
Explanation:
Remember, matter can neither be created nor destroyed, so every atom of reactant the leftt side of the equation must be accounted for in the products on the right side of the equation. With magnesium and hydrochloric acid we have: Mg + 2HCl → MgCl2 + H2(g). Magnesium is divalent, and so requires two chloride ions to form magnesium chloride. Hydrogen gas is a diatomic molecule, so the reaction requires the product to be H2. Going across the equation from left to right we have 1 atom of magnesium (accounted for on the right side of the equation), and on the left, 2 moles of hydrochloric acid; the two hydrogens represented on the left of the equation are accounted for on the right of the equation. Likewise, the two chloride anions on the left of the equation are accounted for in the formation of MgCl2 on the right. When all the atoms are accounted for on both sides of the equation, we say the equation is "balanced".

Uranium-238 is a non- fissile element. It is a radioactive isotope that can be best used to determine geological formations. Thus, option 4 is correct.
What are radioactive isotopes?Radioactive isotopes are elements that have an unstable atomic nucleus and can undergo radioactive decay to produce new particles and energy. They have the same atomic number as that of their parent species.
Isobars are a substance that has atomic mass and do not include uranium. Nuclear fusion and fission are the processes of nuclear energy that combine or splits the unstable nucleus to form a new particle.
Therefore, option 4. Uranium-238 is a radioactive isotope.
