by extracting hydrogen from it
by converting it into liquid fuels
by making suitable bacteria act on it
by burning it directly
by mixing it with petroleum-based fuels
Answer:
The correct ways to use biomass as a source of energy are:
By converting it into liquid fuels: Biomass can be processed into liquid biofuels like biodiesel and bioethanol, which can be used as alternatives to fossil fuels.
By burning it directly: Biomass can be burned directly as a source of heat and energy. This is often done in the form of wood, agricultural residues, or dedicated energy crops.
By making suitable bacteria act on it: Biomass can be used to produce biogas through a process called anaerobic digestion, where bacteria break down organic materials to generate methane, a valuable energy source.
Explanation:
Marinades containing vinegar, wine, or yogurt can tenderizemeat due to their acidity. The acidity breaks down collagen, a tough protein, making the meat more tender.
Marinades that contain vinegar, wine, or yogurt are able to tenderize meat by breaking down collagen into smaller polypeptides because of their acidity.
These ingredients are acidic in nature, and this acidity helps to break the bonds in protein strands, making them more tender.
Specifically, the acid in these marinades works to break down the collagen in the meat, a tough protein that can make meat difficult to chew.
By breaking down the collagen, the marinade makes the meat more tender and easier to eat.

Answer: The stratum granulosum
Explanation: It is called the grainy layer because it contains keratin-filled granules
The 'grainy cells' layer of the epidermis is the stratum granulosum. This layer gets its grainy look from the keyword proteins keratin and keratohyalin produced by the keratinocytes as they move from the stratum spinosum. These proteins create granules within the cells, giving the layer its appearance.
The layer of the epidermis known as the 'grainy cells' is the stratum granulosum. This layer gains its grainy appearance due to changes in the keratinocytes as they move from the stratum spinosum. These cells, which are three to five layers deep, become flatter and their cell membranes thicken. Additionally, they generate a large amount of the proteins keratin and keratohyalin. These proteins accumulate within the cells, creating the appearance of granules, hence the 'grainy' description. As the cells die, they leave behind keratin, keratohyalin and their cell membranes to form the subsequent layers of the epidermis: the stratum lucidum, the stratum corneum, and other structures such as hair and nails.

hypertonic solution
isotonic solution
Answer: The correct answer for the blank is- hypertonic solution.
A hypertonic solution is the one that contains higher solute concentration as compared to solvent. When a cell is placed in hypertonic solution, it will loose water through osmosis ( as water always moves from an area of low solute concentration to an area where solute concentration is comparatively higher).
Thus, animal cell will shrink ( due to loss of water) when placed in a hypertonic solution.
The statement that is correct about organelles that provide energy is that (They are responsible for cellular respiration).
The organelles are cellular structures that have specific functions.
The organelle that provides energy to cells is known as mitochondria.
The mitochondria:
Cellular respiration are metabolic processes that occurs living cells through which they generate energy for their use.
