What kind of adaptations could have given homosapiens an evolutionary advantage over neanderthals and other species of humans?
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.

Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.

Why is it an important property for water to be less dense as a solid?
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.

A normal cell has a high concentration of potassium on the inside and a low concentration of potassium on the outside. Also, a normal cell has a low concentration of sodium on the inside and a high concentration on the outside. Yet, the net movement of potassium is into the cell and the net movement of sodium is out of the cell. What type of transport is involved?
Osmosis
Facilitated diffusion
Active transport
Diffusion
Answer:
Is there a higher concentration of potassium inside or outside the cell?
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

Chromatids are distributed to the 2 daughter nuclei Group of answer choices
M
G2
S
G1
Answer:
M
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:
M phase

One study factored in fluoride levels in the bone near tumors. If there was a connection between osteosarcomas and fluoride, what would have been the outcome?
Answer:
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.
What are the uses of fluoride ?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.

Describe fully what will occur if a plant cell is placed in a solution that has a higher water potential than the cell. Use the following terms in your answer.cell wall, freely permeable, partially permeable, cell surface membrane, vacuole, tonoplast, cytoplasm, solute potential, pressure potential, water potential, turgid, osmosis, protoplast, equilibrium
Answer:
tortinos
Explanation:
hot pizza rolls
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.
What is the plant cell in a hypotonic solution?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.
