Locate the false statement below. Lysosomes help to digest worn-out or damaged organelles. Lysosomes synthesize proteins from th
Sauron [17]

Answer: Lysosomes synthesize proteins from the recycled amino acids.

Explanation:

This is a cell organelle with a spherical sac shape, bounded by a single membrane.( Unlike chloroplast and mitochondrial which  double membranes.) It contain digestive enzymes which is hydrolytic in nature, this splits molecules by addition of water molecules. The digestive enzymes are separated from other cell organelles because of autolysis/autophagic which is automatic discharge of digestive enzymes in a contained cell which destroy the whole cell.

T<u>hey  release  vesicles  containing the enzymes towards the target structure,and the  vesicle  fused with the membrane of the target cell to discharged the hydrolytic  enzymes for digestion</u>

They breakdown old and worn out cells organelles, or the whole cell (for example the breakdown of mammary glands after lactation. Lysosomes are also used to digest bacterial in white blood cells by ENDOCYTOSIS.

Note: RIBOSOMES  play a role in protein Synthesis not LYSOSOMES.

Their average size is 0.1-0.5µm in diameter

How much CO2 does natural gas emit compared with other fossil fuels?
telo118 [61]
How much carbon dioxide is produced when different fuels are burned?

Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content.

Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels:

<span><span> Coal (anthracite) 228.6</span><span> Coal (bituminous) 205.7</span><span> Coal (lignite) 215.4</span><span> Coal (subbituminous) 214.3</span><span> Diesel fuel and heating oil 161.3</span><span> Gasoline 157.2</span><span> Propane 139.0</span><span> Natural gas<span> 117.0</span></span></span>

rewona [7]

Answer: Option D.

Damage to inner ear.

Explanation:

Cochlea damage or inner damage causes permanent hearing loss.

It is the inner ear of Bob that is damaged because the inner ear is responsible for changing soundwaves to electrical waves because the inner ear make the brain to hear and understand sounds and therefore keeping balance . So damage to the inner ear causes hearing loss and inability to understand what is heard because the cochlea of the inner that change soundwaves to electrical signals or nerve impulses which allow the brain to hear and understand is damaged.

Some other symptoms of inner ear damage are;

Dizziness or spinning sensation (vertigo)

Nausea and vomiting.

Problems with balance or walking.

Hearing loss (or decrease in sound volume) in one ear.

Earache or ear pain.

Fever (sometimes)

Feeling of fullness in the ear.
