Suppose an explorer discovered a unique new species of plant and collected a sample for analysis by a geneticist. The geneticist then isolated chromatin from the plant sample and examined the chromatin using electron microscopy. The chromatin observed was organized in a way that is similar to beads on a string A small amount of nuclease was then added, which was observed to cleave the string into individual beads that each contained 280 bp of DNA.
Histone H1 H2A H2B H3 H4 H7 (new histone)
Percentage 12.5% 25% 25% 0% 26%
After thorough digestion with more nuclease, only a 120 bp fragment of DNA remained attached to a core of histone eins. Analysis of the histone core revealed the data dicated in the table to the right.
Using the data provided, determine the conclusions that the geneticist could make about the likely structure of the nucleosome in the chromatin of this new plant species
A. The nucleosome core contains a heterodimer of the histones H7 and H1
B. The nucleosome core contains two each of histones H2A, H2B, and H4
C. The nucleosome core contains a homodimer of the histones H2A, H2B, and H4
D. The nucleosome core contains one each of histones H1 and H7
E. The nucleosome core histone H7 replaces the standard histone H3

Answers

Answer:

diurnal means awake during the day, and use the light to their advantage

nocturnal active at night.

Explanation: Diurnal means active during the day, such as a mosquito meanwhile, a nocturnal animal or being is only active during the night, and sleeps the day away, such as a bat

Hope this helps ^^

Diurnal means awake during the day time, and use the light to their advantage. Nocturnal means active at night time. Thus, the correct options will be A and B.

What is Diurnal and Nocturnal?

Based on the activeness of an organism during a day or 24 hours time period, the animals or organisms can be classified into two different types which are nocturnal and diurnal organisms. Nocturnal animals are the animals which are most active during the night time, and diurnal animals are the animals which are active during the daytime.

Diurnal animals are those animals which are awake during the day time, and use the light energy to their advantage. Nocturnal animals are the animals which are active at the night time.

Therefore, the correct options will be A and B.

The ability to taste PTC comes from the presence of a dominant allele (T). A population of 20 individuals was surveyed to determine whether or not they could taste PTC. Sixteen out of the twenty surveyed could taste PTC. Four could not taste PTC. Assume that Hardy-Weinberg Equilibrium conditions are met in the population. Round all answers properly to 2 decimal digits. Rounding rules: When rounding to 2 decimal digits, look at the third decimal digit. If the third digit is 5 or greater, round up. If the third digit is less than 5, round down.

Answer: B

Explanation:

These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.

Answers

Answer:

1) A mutation appeared in one weed plant that made that weed not   susceptible to the herbicide ( B )

2) The weed will survive long enough to reproduce ( B )

Explanation:

1) The most likely reason the weed remained is :  A mutation appeared in one weed plant that made that weed not susceptible to the herbicide

The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now

2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce

The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
