Biomolecules are made by living organisms and they are made because they are functional. Biomolecules, or at least most of them, do not exist outside of living organisms because they are too complex to be created by chance chemical collisions. The odds of a single average sized protein to form by chance has been calculated at 1 out 10 to the 77th power. Biomolecules REQUIRE intelligent agency to form them.

The four main purposes of biomolecules are:

1. Structure (some proteins)

2. Energy storage and release (carbohydrates)  

3. Protective layers (lipids)

4. Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)

A mechanical wave can only travel through matter.

Answer:

15,00kg

Explanation:

here's your solution

=> force = 45,000N

=> acceleration = 30m/s^2

=> mass = ?

=> Mass = force/acceleration

=> mass = 45,000/30

=> mass = 15,00kg

Answer:B

Explanation:

Answer:

(c) 2

Explanation:

Heat transfer across the walls due to conduction is given by:

[tex]q = -KA\frac{\Delta T}{L}[/tex]

where,

q = heat transfer rate

K = thermal conductivity

A = Area

ΔT = change in temperature

L = thickness

For wall A:

[tex]q_A = -K_AA\frac{\Delta T}{L_A}[/tex]

For wall B:

[tex]q_B = -K_BA\frac{\Delta T}{L_B}[/tex]

Because the change of temperature and area of walls are the same. Dividing both terms:

[tex]\frac{q_A}{q_B} = \frac{\frac{K_A}{L_A} }{\frac{K_B}{L_B}}\\\\ \frac{q_A}{q_B} =\frac{\frac{K_A}{K_B} }{\frac{L_A}{L_B}}[/tex]

using values given in the question:

[tex]\frac{q_A}{q_B} = \frac{4}{2}\\\\\frac{q_A}{q_B} = 2[/tex]

Therefore, the correct answer is:

(c) 2

Answer:

K.E = 248 J

Explanation:

Since the child is travelling at a given velocity. The kinetic energy of the child down the hill can be given by the following formula:

[tex]K.E = \frac{1}{2}mv^2\\[/tex]

where,

m = mass of the child = 31 kg

v = velocity of the child = 4 m/s

Therefore,

[tex]K.E = \frac{1}{2}(31\ kg)(4\ m/s)^2\\[/tex]

K.E = 248 J

Answer:

611.064 kJ

Explanation:

Given :

m = 200 mL = 200 g

Specific heat of ice = 2.06 J/g°C

Q = mcΔt

Δt = 0 - (-22) = 22

Q1 = 200 * 2.06 * 22 = 9064 J

Q2 = Melt 0 °C solid ice into 0 °C liquid water:

Q2 = m · ΔHf ; ΔHf = heat of fusion of water = 334j/g

Q2 = 200 * 334 = 66800 J

Q3 : Heat to convert from 0°C to 100°C

Q3 = mcΔt ; c = 4.19 J/g°C ; Δt = (100 - 0) = 100

Q3 = 200 * 4.19 * 100 = 83800 J

Q4: heat required to boil water to steam

Q = m · ΔHv

Hv = heat of vaporization of water = 2257 J/g

Q4 = 200 * 2257 = 451400 J

Total Q = Q1 + Q2 + Q3 + Q4

Q = 9064 + 66800 + 83800 + 451400

Q = 611,064 Joules

Q = 611.064 kJ

Answer:

Explanation:

potential energy is energy due to position

The current is increased by a factor of 8.

From 18/35 A. to 144/35 A.

The electric current changes from 0.514 ampere to 4.14 ampere, i.e, electric current flow in the circuit increases 8 times.

A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.

Initial electric current flowing through the circuit = (18 volt ÷ 35 ohms)

= 0.514 ampere.

When the initial voltage of 18 V is doubled, and the initial resistance of 35 Ohms is reduced by a factor of 4, electric current flowing through the circuit will be = (2 × 18 volt )÷ (35 ohms÷4)

= 4.114 ampere.

Hence, electric current changes from 0.514 ampere to 4.14 ampere, i.e., electric current flow in the circuit increases 8 times.

Answer:Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.

Explanation:

The phenotype is the trait those genes express. ... Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene. This means there is a 100% chance of the offspring having brown eyes, or being BB. It's important to note here that each box represents a possible offspring.

Answer:14C

Explanation:

Hello. You did not present the photos to which the question refers, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way.

Your question informs us that the photos are of a star-forming molecular cloud. The molecular cloud has dust, especially when the star is forming. In this case, we must keep in mind that in photos taken in visible light, the dust is able to appear, especially in space, where this dust would not reflect light, unlike the star in formation. In this case, we can conclude that in the case of the photo taken in visible light, we could see the molecular cloud as a dark spot, due to the dust. However, it would not be possible to view it in a photo taken with infrared light.
