Answer:

The skeletal muscle tissue is found in biceps.

=> Option B is correct

Hope this helps!

:)

There are different types of muscles namely smooth muscles, skeletal muscles, non-striated muscles etc. Biceps brachii is classified as skeletal muscles.

Skeletal muscles are controlled by the somatic nervous system and are voluntary muscles. The other types of muscle include smooth muscle, which is non-striated, and cardiac muscle, both of which are striated. These two types are both considered to be involuntary, or under the direction of the autonomic nervous system.

The biceps brachii commonly know as the biceps, is a large, thick muscle on the ventral portion of the upper arm. The muscle is composed of a short head and a long head. The long head is located on the lateral side of the biceps brachii while the short head is located on the medial side[1].

The biceps brachii works across three joints, and is able to generate movements in glenohumeral, elbow and radio-ulnar joints.

Answer:

The new volume of the gas is 29.57 Liters

Explanation:

Given;

initial pressure of gas, P₁ =  12 atm

initial volume of gas, V₁ = 23 Liters

initial temperature of gas, T₁ = 200 K

final pressure of gas, P₂ =  14 atm

final temperature of gas, T₂ = 300 K

final volume of gas, V₂ = ?

To determine the final volume of the gas, we apply general gas law;

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\\\V_2 = \frac{P_1V_1T_2}{T_1P_2}\\\\V_2 = \frac{12*23*300}{200*14}\\\\V_2 = 29.57 \ Liters[/tex]

Therefore, the new volume of the gas is 29.57 Liters

Answer:

The answer is 2.660 mol/l

Explanation:

Given: n= 0.0665, v= 25.00ml

Required: C

C (molarity)= n (of solute)/ v (of solvent) [ standard unit: mol/l]

First convert volume of solvent in its standard unit, i.e. litres(L)

v= 25.00ml/1000= 0.02500L

C = 0.0665 mol / 0.02500 L= 2.660 mL (In proper significant digits i.e. 4 sigdigs)

Therefore, The molarity of the sulfuric acid is 2.660 mol/L :)

Answer:

fluoride ion

Explanation:

If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.

hope that helps!

When a fluorine atom will gain electrons then it will form an anion,[tex]F^{-}[/tex].

An ion having a negative charge, or one with more electrons than protons, is referred to as an anion. When an element acquires one or even more electrons, anion formation was observed.

The smallest component of ordinary stuff that makes up a chemical element is just an atom.

Atoms generate negative ions, or anions when they gain electrons.  A fluorine atom is generally electrically neutral since it possesses nine protons as well as nine electrons. Gaining an electron causes a fluorine atom to will have to become a fluoride ion, which has an electric charge of such -1.

ecosystem

Explanation:

An ecosystem includes all of the living things (plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments (weather, earth, sun, soil, climate, atmosphere). The living and nonliving components of the ecosystem are linked together through nutrient cycles and energy flows. Ecosystems are of any size, but usually they are in particular places.

In an ecosystem, plants depend on the soil for nutrients. These nutrients are cycled in nature by the various biogeochemical cycles within the ecosystem. The ecosystem is a self sustaining unit in terms of materials and energy flow.

Answer:

D. ecosystem

Explanation:

An ecosystem is a large community of living organisms (plants, animals and microbes) in a particular area. The living and physical components are linked together through nutrient cycles and energy flows.

In an ecosystem there is symbiotic relationship which entails each living organism contributes to the well being of the other and the entire population.

Answer:

The volume is 1.2L

Explanation:

Initial volume (V1) = 700mL = 0.7L

Initial temperature (T1) = 7°C = (7 + 273.15)K = 280.15K

Initial pressure = 106.6kPa = 106600Pa

Final temperature (T2) = 27°C = (27 + 273.15)K = 300.15K

Final pressure (P2) = 66.6kPa = 66600Pa

Final volume (V2) = ?

To solve this question, we need to use combined gas equation which is a combination of Boyle's law, Charles Law and pressure law.

(P1 × V1) / T1 = (P2 × V2) / T2

solve for V2 by making it the subject of formula,

P1 × V1 × T2 = P2 × V2 × T1

V2 = (P1 × V1 × T2) / (P2 × T1)

V2 = (106600 × 0.7 × 300.15) / (66600 × 280.15)

V2 = 22397193 / 18657990

V2 = 1.2L

The final volume of the gas is 1.2L

Explanation:

Answer:

Chemical potential energy is a form of potential energy related to the structural arrangement of atoms or molecules. This arrangement may be the result of chemical bonds within a molecule or otherwise. Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction.

The chemical energy and nuclear energy can be considered potential energy because both of them has energy stored in it.

Potential energy is any form of energy that has stored potential that can be put to future use such as nuclear energy, chemical energy in which the energy is stored in it so we can conclude that chemical energy and nuclear energy can be considered potential energy due to its storage of energy.

Explanation:

The first step is to determine how many moles of glucose there are, which means first finding out the molar mass of glucose. Carbon has a molar mass of about 12, hydrogen 1, and oxygen 16, so the total molar mass of glucose is about 6(12)+12(1)+6(16)=180 grams. This means that 90 grams is half a mole. Half a mole of substance divided by two liters of solution is (1/2)/2=1/4, or a molarity of 0.25. Hope this helps!

When water changes to a solid or gas, it's said that water changes to a different state of matter

Explanation:

Even when water physical form changes, the molecules stay the same. Water's molecules contains two hydrogen atoms that is bonded with one oxygen atom.

Answer:

The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.

Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.

Water molecules is Siphoned, pull by force of gravity through the sand, past  the filter paper to emerge as clean in the beaker below.

Answer:

Carbon (C)

Explanation:

Because the element is the element of the main subgroup of group IV , it has oxidation number +4 in the oxide, and oxide formula is EO2.

reaction:

                                     EO2 + H2O ---> H2EO3

from reaction               1 mol    1 mol       1 mol

31 g acid - 22 g oxide = 9 g water

M(H2O) = 18 g/mol

9g * 1 mol/18 g = 0.5 mol H2O

As we see from reaction molar ratios EO2 : H2O : H2EO3 = 1 : 1 : 1,

so if  we have 0.5 mol H2O , we also have 0.5 mol EO2.

0.5 mol EO2 has mass 22 g.

Molar mass(EO2) = mass/ number of moles = 22 g/ 0.5 mol = 44 g/mol

Molar mass (EO2) = M(E) + 2M(O) = 44 g/mol

M(E) + 2 *16 g/mol = 44 g/mo

M(E) = 44-32 = 12 g/mol

Molar mass 12 g/ mol is molar mass of carbon.

So, element is carbon (C).

The shampoo by nature is of basic pH.

Explanation:

Since the basic shampoo weakens the hair by breaking the disulfide bonds of the keratin of the hair, it is sought to slightly acidify adding small flakes of various materials, for example, glycol distearate.  

The shampoos hardly have the pH indicated, the most common is to see shampoo with balanced or neutral pH (pH 7). To know the pH of the shampoo you can buy pH measuring strips. A pH between 5.5 and 7 is correct.

A physical change has occurred has occurred when evaporating water producing gaseous water as a  physical change  results in a phase change, not a change in composition.

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.
