the diagram shows patches of habitat that are either colonized (red dots) or not colonized (green dots). which conclusion can be drawn from the data? exam 2 patch group of answer choices patches that are very close to another occupied patch or that have large areas are most likely to be colonized. patches that have the largest area and are farthest away from another occupied patch are most likely to be colonized. patches that have the smallest area and are closest to another occupied patch are most likely to be colonized. patches with the smallest area are most likely to be colonized; the distance to the nearest occupied patch does not affect colonization rates.
The correct option is C .Patches that are very close to another occupied patch or that have large areas are most likely to be colonized.
How the patches are look like in the diagram?
The most probable patches to be colonized are those that are close to other occupied patches or have sizable expanses.
The distance to the nearest occupied patch does not appear to affect colonization rates. This can be inferred from the fact that red dots are present throughout the diagram, rather than being concentrated in one area.
The size of the patch may play a role in colonization rates, as there are several large red dots indicating that larger patches are more likely to be colonized.
It is not possible to draw a conclusion about the relationship between patch size and colonization rates based on this data.
And more data would be needed to determine any correlation between patch size and colonization rates.

essential question: how do materials move into and out of the cell through a membrane? 1. pre-lab questions: (respond in complete sentences
Materials move into and out of the cell through a cell membrane by the process of diffusion.
Plasma membrane is a selectively permeable membrane which allows only a few substances to move in and out of it. The most direct transfer techniques use passive membranes. Natural processes like passive transport take place without the cell using energy to move. Chemicals move passively from a location of higher concentration to a region of lower concentration through a process called diffusion. A concentration gradient is a difference in the concentration of one substance throughout a physical region. If molecules are passes against the concentration gradient, it happens through active transport. Ions, glucose, and amino acids move through the membrane via active transport in opposition to the concentration gradient. It requires ATP, the chemical component of cellular energy. The membrane's protein molecules serve as channels via which molecules can move.

you and 19 friends build a raft, sail to a deserted island, and start a new population, totally isolated from the world. Two of your friends carry (that is, are heterozygous for) the recessive cf allele, which in homozygotes causes cystic fibrosis A. Assuming that the frequency of this allele does not change as the population grows, what wil be the instance of cystic fibrosis on your island? B. Cystic fibrosis births on the island is how many times greater than the original mainland. The frequency of births on the mainland is .059%.
Answer:
A. Assuming that the frequency of the recessive cf allele does not change as the population grows, the instance of cystic fibrosis on the island would be relatively low. The allele is recessive, meaning that it only causes the disease when present in a homozygous state (i.e. two copies, one from each parent). Since only two of your friends carry the allele, the probability of any two of your friends having children with cystic fibrosis would be (2/20)*(1/19) = 1/190 or 0.52%.
B. Cystic fibrosis births on the island would be 0.52% / 0.059% = 8.8 times greater than the original mainland. However, it's important to note that the population is small and it may be not possible to predict the exact frequency of cystic fibrosis based on the frequency of the allele in such a small group of people.

The homologous double-chromatid chromosome pairs cross across and frequently swap chromosomal segments during prophase of meiosis I. In order to produce chromosomes with a diverse genetic makeup, this recombination allows genes from each parent to mix, resulting in genetic diversity.
What is meiosis I?The process by which most eukaryotic organisms—those whose cells have an ordered nucleus—produce sex cells, or the male and female gametes—is called meiosis. Two copies of each chromosome, one from each parent, are typically present in cells. The paired chromosomes are known as homologous, and this chromosome condition is diploid. One copy of each chromosome is found in each of the four haploid granddaughter cells that meiosis creates from a diploid cell. A species' genetic diversity is boosted through the procedure.Two cell generations go through meiosis at once. Each chromosome undergoes a normal cell division process called mitosis during which it is duplicated, resulting in twin sister chromatids on each chromosome. To create the following generation of identical chromosomes, these linked chromatids later split during mitosis. Each daughter cell only obtains one copy of each chromosome, or the haploid number, and each copy contains two chromatids during meiosis I since the chromatids do not separate during this process.

Farmlands located near coastal regions are being threatened by encroaching seawater seeping into the soil. In terms of water movement into or out of plant cells, explain why seawater could decrease can't put action. Include a discussion of water potential in your answer
Due to the difference in water potential between seawater and soil, seawater can reduce crop growth on farmland near coastal areas. Pressure, temperature, and concentration all have an impact on Osmosis
water potential, which is a measurement of the energy state of water. Due to its high salt content, seawater has a far higher water potential than soil. Osmosis will then transfer water from the soil to the ocean. As a result, the soil may become salt-saturated, which will make it challenging for plants' roots to absorb water and nutrients.
Water can enter plant cells by osmosis and is absorbed by plants through their roots. Water molecules flow by osmosis from a high water potential (lower solute concentration) location to a low water potential area (higher solute concentration). The entry of seawater causes the water potential in the soil to decline, which in turn causes the water potential in plant cells to decline and makes it more difficult for water to enter the cells. The cells may become dehydrated as a result and unable to perform their functions.
