Answer:
A botfly that lays an egg in the skin of an animal when the larvae hatches from the egg, it burrows deep into the skin. The animal that may become sick from having the larvae under its skin is called Mutualism.
Explanation:
The animal is the host while the botfly is the parasite. A mutualism in which one mutualistic partner removes parasites, as well as dead or diseased skin from another, in return receiving a steady supply of food is called Pollination. Nearly all pollination services involve a mutualism that has evolved over millions of years. Another example is reproduction.

Waters density is 1 g/cm^3. Glass has a density of 2.8 g/cm^3. Will glass float in water?
YES, it will float because its density is greater than the density of water/
This question cannot be answered because density does not determine buoyancy
NO, it will not float because its density is greater than the density of water
Explanation:
It will not float on water
Substances with their densities less than that of water usually float on it and those with their densities greater than that of water will sink into it.
From the question the density of glass is 2.8 g/cm³ and this is greater than the density of water which is 1 g/cm³. Therefore glass will not float on water.

Explain what is cellular growth and repair? Why is it important?
Answer:
Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

A sample of He collected over water at a temperature of 20C has a pressure of 705 torr. What is the pressure of the dry gas? The vapor pressure of water at 20 degrees * C is 17.5 torr.
The pressure of the dry gas : 687.5 torr
Further explanationDalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
Since the gas mixture consists of He and H₂O :
P tot=P He + P H₂O
[tex]\tt 705=P~He+17.5\\\\P~He=705-17.5=687.5~torr[/tex]

The pH of a solution of 3-hydroxypropanoic acid is measured to be . Calculate the acid dissociation constant of 3-hydroxypropanoic acid. Be sure your answer has the correct number of significant digits.
Answer:
3.1 × 10⁻⁵
Explanation:
The pH of a 0.53 M solution of 3-hydroxypropanoic acid (HC₃H₅O₃) is measured to be 2.39. Calculate the acid dissociation constant of 3-hydroxypropanoic acid. Be sure your answer has the correct number of significant digits.
Step 1: Given data
Concentration of 3-hydroxypropanoic acid (Ca): 0.53 MpH of the solution: 2.39Step 2: Write the acid dissociation reaction
3-hydroxypropanoic acid is a weak acid that dissociates according to the following equation.
HC₃H₅O₃(aq) ⇄ C₃H₅O₃⁻(aq) + H⁺(aq)
Step 3: Calculate the concentration of H⁺
We will use the definition of pH.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -2.39 = 4.07 × 10⁻³ M
Step 4: Calculate the acid dissociation constant (Ka) of 3-hydroxypropanoic acid
We will use the following expression.
Ka = [H⁺]² / Ca
Ka = (4.07 × 10⁻³)² / 0.53
Ka = 3.1 × 10⁻⁵

At which temperature could air hold the most water vapor?
Answer:
Now, what happens if we turn the room thermostat up to 80 degrees F? Looking at your Capacity of Saturated Air table, you can see that as air temperatures rise, there is an increase in the ability of the air to hold moisture. At 80 degrees F the capacity of air increases to where it can hold 21.537 g/kg of water vapor.

Which action would shift this reaction away from solid calcium fluoride and toward the dissolved ions?a) adding calcium ionsb) adding fluoride ionsc) removing fluoride ionsd) removing calcium fluoride
Answer:
c) removing fluoride ions.
Explanation:
Hello!
In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:
[tex]CaF_2(s)\rightleftharpoons Ca^{2+}(aq)+2F^-(aq)[/tex]
In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.

Elements in a vertical column on the Periodic Table have similar properties and are all members of the same
of elements.
Answer:
ok thx for the imformation can you help me with my qustion
Explanation:
Due to their comparable chemical activity, the periodic table's vertical columns are referred to as groups or families. The number of valence electrons and chemical characteristics are the same for all members of a family of elements.
What is properties in vertical column on the Periodic Table?The vertical columns of the periodic table also have a unique name. A group is what we call each column.
Each set of elements has an equal number of electrons in the outer orbital. The outer electrons are sometimes referred to as valence electrons.
The same valence shell electron arrangement gives the elements in the same group comparable chemical characteristics.
Because the valence shell electron configuration of the elements changes gradually along the row, the elements exhibit a gradual change in their chemical characteristics.
Therefore, elements in a vertical column on the Periodic Table have similar properties.

The Beryllium (Be) atom is smaller than the Barium (Ba) atom. Choose the evidence statement that best supports this claim. A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 8 electron shells. A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 8 electron shells. A Beryllium (Be) atom has 3 electron shells, whereas a Barium (Ba) atom has 8 electron shells. A Beryllium (Be) atom has 3 electron shells, whereas a Barium (Ba) atom has 8 electron shells. A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells. A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells. A Beryllium (Be) atom has 1 electron shells, whereas a Barium (Ba) atom has 6 electron shells.
Answer:
A Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells
Explanation:
Beryllium (Be) is an element in group two of the periodic table with atomic number 4 (Is2 2s2). On the other hand, barium (Ba) is an element in group 2 of the periodic table with atomic number 56. However, as stated in the question, the Beryllium (Be) atom is smaller than the Barium (Ba) atom.
This is because a Beryllium (Be) atom has 2 electron shells, whereas a Barium (Ba) atom has 6 electron shells. The electron shells of Barium contains more electrons, which is responsible for the large size of the Barium atom. Note that, the higher the number of atoms, the larger the atomic size.

Calculate the nuclear binding energy in mega-electronvolts (MeV) per nucleon for Th232. Th232 has a nuclear mass of 232.038 amu.
Answer:
1720 MeV
Explanation:
Thorium has 90 protons and 142 neutrons
The mass of each proton is 1.007277 amu
The mass of each neutron is 1.008665 amu
The mass of 90 protons is 90 * 1.007277 amu = 90.65493 amu
The mass of 142 neutrons is 142 * 1.008665 amu = 143.23043 amu
Total calculated mass of nucleons = 90.65493 amu + 143.23043 amu = 233.88536
Mass defect = 233.88536 amu - 232.038 amu = 1.84736 amu
We convert from amu to MeV using the conversion factor of 931
Binding energy = 1.84736 amu * 931 = 1720 MeV
