Explanation

The cell wall of prokaryotes is made of carbohydrates and proteins.

The compound is peptidoglycan or mucopeptide in which a short peptide is attached to murein or muramic acid.

Explanation

When changing gears while driving, the driver needs to maintain proper focus 

Here's why the driver should not bow their head and look down:

1. Maintain Visibility

2. Stay Alert

3. Ensure Safety

4. Proper Technique

Explanation

To find the wavelength of a wave with a period of 2 seconds and a speed of 2 cm/s, we can use the wave equation:

Wave speed = Wavelength x Frequency

Given information:

- Period = 2 seconds

- Speed = 2 cm/s

To find the frequency, we can use the equation:

Frequency = 1 / Period

Calculating the frequency:

Frequency = 1 / 2 seconds = 0.5 Hz

Now, we can rearrange the wave equation to solve for the wavelength:

Wavelength = Speed / Frequency

Substituting the given values:

Wavelength = 2 cm/s / 0.5 Hz

Simplifying the expression:

Wavelength = 4 cm

Explanation

The rapid motion of water across a horizontal surface is due to the current

A horizontal movement of water often accompanies the rising and falling of the tide. This is called the tidal current.

Additional Information:

Ocean water moves in two directions:

1. Horizontal movements are referred to as currents
   
2. Vertical changes are called upwellings or downwellings.
   

Explanation

the widening of a river when it opens into the sea is known as an estuary.

Estuaries are vital ecosystems that support diverse life forms

Examples are San Francisco.

Additional Information:

Meander:

It is a series of curves, bends, and loops that turn in the channel of a river 

Gorge:

It is a narrow valley between hills and mountains and a stream flows through it

Creek:

It is a stream tributary of a river

Explanation

Wind blows on the Earth due to uneven heating of the Earth's surface.

The wind blows from a high pressure region to a low-pressure region.

The boundary between these two areas is called a front

Explanation

All animals and plants need water to survive, and the human body is more than three-fourths water.

Life forms use water to carry nutrients around the body and to take away waste.

Explanation

The electron transport cycle generates around 30–32 ATP molecules

Both photosynthesis and cellular respiration take place in mitochondria.

By transferring electrons from NADH and FADH2 through a series of complexes and electron carriers, these carriers ultimately produce ATP.

Explanation

The enthalpy is defined by H = E + pV for a change in the states of a system.

ΔH = Δ (E + pV) = ΔE + Δ (pV) = ΔE + pΔV + VΔp 

Enthalpy, H, is a thermodynamic property that describes the heat lost or gained in a system.

The change in enthalpy, ΔH, is equal to the sum of the change in internal energy, ΔU, plus the product of the constant pressure, P, and the change in volume, ΔV.

Explanation

intercalary meristems are found at the bases of young leaves and internodes.

They are mainly responsible for further lengthening of stems and leaves.

Additional informational:

Meristematic cells are also responsible for keeping the plant growing.

The Shoot Apical Meristem (SAM):

• SAM gives rise to organs like the leaves and flowers

The Root Apical Meristem (RAM):

• RAM provides the meristematic cells for future root growth.
