How does this model support the conclusion that cells need to have a high amount of surface area relative to their total volume?
Answers
Answer:
Due to increase of surface area, the nutrients move efficiently inside the cell.
Explanation:
The cells need to have a high amount of surface area as compared to their total volume because with increase of surface area, the nutrients move efficiently inside the cell. A large surface area to volume ratio indicates that the cell can be efficient in moving nutrients and waste materials around using through the process of diffusion but when the volume increases instead of surface area, the efficiency of the cell decreases, and cells won't be able to do its job efficiently.

Two equal strips A and B were from a potato whose cell was 30% of sugar. The strip
A was placed in a solution of 10% sugar concentration while B was placed in 50%
sugar concentration
a) What change was expected in strip A and B
b) Account for the change in strip A
Answers
Answer:
Movement occurs from higher concentration to lower concentration.
Explanation:
Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.
Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell
Simple diffusionSalts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution
Water also diffuses away from areas of high free water concentration into areas of more solute concentration.here in strip A is placed in low sugar solution that causes movement or diffusion of water from the cell to the solution as it is only 10% sugar concentrationin strip B which is placed in low sugar solution that is placed in high sugar concentration solution that is 50% which means there will be movement of water from solution into the cells of the strip which cause them to swellThus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50% sugar concentration
a) strip become flaccid and strip B will swell
b) hypotonic solution causes movement of water to diffuse out of cell

variation in a population exists
Answers
Answer:
variation in a population exists
Explanation:
Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

NASA scientists use satellites to monitor two important factors that lead too landslides
Answers
Answer:
The most important factors that lead to landslides are the declivity of the terrain and the type of soil.
Explanation:
Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.

Know how to calculate the amount of chromosomes in mitotic cells and in gamete cells, when given an amount of the chromosome number for one of the two types of cells. For example, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, how many chromosomes will be in each egg cell?
Answers
Answer:
4 chromosomes
Explanation:
Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).
According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.
Meiosis produces four nuclei that have different chromosome numbers

Track the evolutionary path of a butterfly and comment on it.
Answers
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.
Explanation:
Please brainliest!
Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria.

How would this food web be affected by the extinction of the Osprey?

Answer:
The fish would grow in the population, because osprey mainly eat fish.
Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.
Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.
