Answer:

Water has a unique density. It is less dense as a solid than it is as a liquid, which is why ice floats on top of liquid water.

Explanation:

Answer: Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water. With most other liquids, solidification when the temperature drops includes the lowering of kinetic energy between molecules, allowing them to pack even more tightly than in liquid form and giving the solid a greater density than the liquid.

The low density of ice, an anomaly, causes it to float at the surface of liquid water, such as an iceberg or the ice cubes in a glass of water. In lakes and ponds, ice forms on the surface of the water creating an insulating barrier that protects the animals and plant life in the pond from freezing. Without this layer of insulating ice, plants and animals living in the pond would freeze in the solid block of ice and could not survive. The detrimental effect of freezing on living organisms is caused by the expansion of ice relative to liquid water. The ice crystals that form upon freezing rupture the delicate membranes essential for the function of living cells, irreversibly damaging them. Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol.

Fluoride levels in the bone would be higher in individuals with osteosarcomas.

Explanation:

Fluoride levels will be higher in bone of the individuals with osteosarcomas.

Fluoride is a group of compounds which is a combination of fluorine and other elements, these compounds are present in water, plants, rocks, air, and soil.

Some of fluoride compounds are sodium fluoride, stannous fluoride, and fluoride mono-fluorophosphate.

Once fluorides are absorbed inside the body, it travels into the blood through the digestive tract, tend to collect in areas with high calcium like  bones and teeth.

Majorly fluorides are used in drinking water, beverages, food, and  dental products, mostly fluoro-silicic acid, sodium fluorosilicate, and sodium fluoride forms are added to water.

Some of the fluoridated water used to prevent tooth decay, and  avoid  dental fluorosis, a cosmetic condition.

Average number of decayed, missing, or filled teeth in children reduced by application of this water and  cavities in adults.

When the plant is placed in the higher water potential, the water will diffuse from the higher water potential to the lower water potential and make the plant cell turgid. As a result, the plant cell will swell.

When a plant is placed in a hypotonic solution, that means the plant cell has less water potential than the outer side, and as a result, the water will flow from a higher water potential to a lower one. The plant cell membrane is partially permeable, and water will diffuse from the outer to the inner, causing the cell to exert more pressure on the cell wall and swell.

The vacuole will swell too in such a case, and the movement of water is called osmosis. The hypotonic solution has less solute potential, and the flow of water will continue until equilibrium is maintained.

Hence, this is the osmosis process, where the water will flow freely from the outside to the inside of the cell cytoplasm and make the cell turgid.

Answer:

humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations

Explanation:

A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.

Explanation:

Mitosis is a type of cell division that involves the production of two daughter cells that are genetically identical to one another. Mitosis encompasses two stages namely: Interphase and Mitotic phase. The interphase which further consists of G1, S, and G2 phases, is a preparatory phase for the cell to grow and replicate its DNA.

However, the separation of the sister chromatids (replicated chromosomes) into two daughter nuclei occurs in the Mitotic or M phase. Note that the M phase comprises of stages that includes: prophase, metaphase, anaphase and telophase.

Answer:

Hyphae; mycelium.

Explanation:

Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.

A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;

I. Yeast.

II. Mushroom.

III. Mold.

A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.

The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.

Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.

mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.

Thus,  hyphae and mycelium is the correct answer.

A eukaryotic plant cell is the correct classification of this cell. So, the correct option is D.

A eukaryotic cell is defined as the type of cell that has a true nucleus, and other organelles are well defined and enclosed in a membrane that has a large and complex cell that distinguishes them from prokaryotes.

This is the cell with a true and well-defined nucleus, lysosomes, cell membrane, and a cell wall is a characteristic of a plant cell because they are enclosed in a cell wall, unlike animal cells. Eukaryotic cells are found in animals and plants, while bacteria and archaea have prokaryotic cells.  

Therefore, a eukaryotic plant cell is the correct classification of this cell. So, the correct option is D.
