Answer:

C.Dispersion

Explanation:

Dispersion is the method in which mixtures of emulsifiers and solvents known as dispersants are used to break the oil into smaller particles for the purpose of cleaning the oil spill.

Since the particles are broken down into smaller droplets they get easily dispersed in the water body and then their biodegradation by microbes takes place which allows for the cleanup.

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O

Homo neanderthal was the most recent ancestor species of modern human as they appear about 40,000 years ago.

They became extinct as they did't fight against environmental hazards and the major cause of their extinction that scientists have claimed that they did't adapt the modern techniques that the modern human does.

Pepsi [2]

Answer:

Yes, the species of a lizard can be identified using dichotomous keys.

Explanation:

A dichotomous key is an identification tool used by the biologists especially taxonomists to identify and classify the organisms.

The dichotomous keys are based on the characteristic feature of an organism for which two which contains two contrasting feature. The dichotomous keys are the most common tools used to classify an organism.

A species of lizard can be identified using these keys by selecting the key characteristic feature shown by the species which could be quantitative like weight, height or it could be qualitative like colour. By comparing these characteristics, it becomes easy to identify the species.

Patches of fibrocartilage formed in the healing of a fracture are called __________, whereas the bony collar formed around the f

SashulF [63]

Answer:

Patches of fibrocartilage formed in the healing of a fracture are called soft callus, whereas the bony collar formed around the fracture is called hard callus.

Explanation:

In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
