Below is the ORIGINAL stretch of DNA, followed by DNA which has a MUTATION. Will this mutation likely have a bad consequence for

Sholpan [36]

No it will not. Since the mutation is towards the end of the codon, it is very likely that it would not change the amino acid at all.

Mitosis is a type of cell division. organize the images below to show the steps of mitosis.

barxatty [35]

Answer:

The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)

Explanation:

Interphase: Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F)
Prophase: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)
Metaphase: The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area. (FIGURE C)
Anaphase: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H).
Telophase: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)
Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D).
Decondensation of the genetic material of each new cell (FIGURE B).

Which statement is true about climate change and biodiversity?

8090 [49]

Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.

Answer: C. It can help some species and hurt others.

HELP!!! How does the equipment shown in the picture reduce the impact of an oil spill on marine life? A. It absorbs the oil as i

asambeis [7]

Answer:

D

Explanation:

An oil boom helps contain the oil so that it is easier for them to skim it off of the water. They aren't meant to clean up oil, only to contain the oil since it does not sink or mix with water.
