1. Answer;
1000 times
If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about 1000 times.
Explanation;
If the surface are increases 100 times it means that the side of a cube has increased by a scale factor of 10, therefore, the volume of the cube will increase about 1000 times ( 10 × 10 × 10 = 1000).
2. Answer;
Moving needed materials in and waste products out.
Explanation;
Large cells have more trouble moving materials that are needed in the cell and wastes products out of the cell, as compared to small cells.
The volume of large cells is so large, the surface area, by comparison, is relatively small, thus large cells have a small surface are to volume ratio, compared to small cells which have a large surface area to volume ratio, which makes the transportation of substances into and out of the cells extremely efficient compared to large cell.
The answers are most likely to be cytoskeleton and microfilaments.
In a eukaryotic cell, the cytoskeleton is what helps the cell maintain its shape. It also help in cell movement during cell division and other cell processes. There are two main fibers that are found in the cytoskeleton; microfilaments and microtubules. Microtubules are a bundle of microfilaments that can assemble and disassemble.
Answer:
Polyploidy is the state of a cell or organism having more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent. Hence ploidy is defined with respect to a cell.
Explanation:
Answer:
Population bottleneck
Explanation:
Population bottleneck can be defined as a sharp decrease in a population size which can be attributed to various environmental influences including fires, hurricane, famines etc.
This leads to loss of alleles and a small population. With a smaller population size, celebrities mutations can occur, producing several inherited disorders.
A hypothesis based on Darwin's observations about the finches would be that the finches originated from the same ancestors, however, they adapted traits over time beneficial to their survival in different regions with different food sources. Also, since the finches with helpful traits (such as beak shape) survived when the ones that didn't have these traits didn't survive, Darwin came up with the idea of natural selection, also known as "survival of the fittest." Hope this helps! :)
