Answer:
Recombination frequency, P = 0.23.
If the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked.
1% of recombinations = 1 map unit23% = 23 map unitsThe genes for stem color and fruit type seem to be in the same chromosome, linked and 23 MP apart.
Explanation:
In the present example, the genes for stem color and fruit type seem to be linked.
To know if two genes are linked, we must observe the progeny distribution. If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.
In this way, we might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny.
The following distribution of offspring is observed:
normal fruit, purple stems 38.5% fasciated fruit green stems 38.5% normal fruit, green stems 11.5% fasciated fruit, purple stems 11.5%38.5% + 38.5% + 11.5% + 11.5% = 100%
N (total number of individuals in the progeny) = 100
number of individuals with normal fruit, purple stems 38.5 number of individuals with fasciated fruit green stems 38.5 number of individuals with normal fruit, green stems 11.5 number of individuals with fasciated fruit, purple stems 11.5To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals. The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).
P = Recombinant number / Total of individuals.
P = 11.5 + 11.5 / 100
P = 0.23
We need to know that 1% of recombinations = 1 map unit = 1cm. Also, the maximum recombination frequency is always 50%. This means that if the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked. FR 23% = 23 UM.

How could biotechnology lead to a decrease in the use of pesticides?
Plants can be genetically engineered through the use of biotechnology to be less susceptible to insects. This trait will make pesticide use less necessary.
This is the sample answer on edge.
This method combines the genetic productivity enhancement of plants with the management of their hazardous organisms.
How is biotechnology used?Typically, agricultural biotechnology is utilized to boost plant production productivity to reduce the use of pesticides.
In agriculture by applying biotechnology, pest management and the use of pesticides will be reduced for modified plants.
The emergence of insect-resistant plants will be accelerated by technological advancements, and with an improved grasp of biotechnological processes, the acceptance of biotechnology goods might grow.
Therefore to reduce paste management and make crop resisitance for paste biotechnology is used.

Answer:
Cloud condensation nuclei or CCNs are small particles typically 0.2 µm, or 1/100 the size of a cloud droplet on which water vapor condenses. Water requires a non-gaseous surface to make the transition from a vapour to a liquid; this process is called condensation.

A simple random sample of 25,000 individuals are surveyed in order to determine the prevalence of individuals that contracted the flu in the past year. Assuming 4,250 individuals indicated they had been diagnosed with the flu at some point in the past year, what is the prevalence of flu for the past year, as indicated from the survey participants?
A. 8.30%
B. 83.0%
C. 17.0%
D. 1.70%
Answer:
C. 17.0%
Explanation:
A random sampling of human populations is done to check the frequency of a particular infection. The proportion of the individuals in the total population that suffered the infection at any time during the year are counted. The proportion of the individuals infected any time during the year is divided by the total number of the individuals surveyed and the percentage is taken to calculate the prevalence of the infection in the sampled population.
Here, the total number of the individuals that were infected with flu in the last year= 4250.
The total number of the checked individuals= 25,000.
So, the proportion of the individuals infected with flu in this population= 4250/25000 x 100= 17%
Answer: It is C. 17.0%

Which stage of the cell cycle happens directly after cytokinesis?
A
mitosis
B
M phase
C
anaphase
D
interphase
The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.
What is the cell cycle's importance?The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.
Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

Do environmental or genetic factors affect growth of organisms most?
Answer:
Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.
I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?
The water that sea otters live in is chilly, ranging from 35 to 60 degrees Fahrenheit—much too cold for humans. Otters don't have blubber to keep them warm like other marine mammals. Instead, they rely on their thick fur coat to maintain a constant body temperature of 100 degrees Fahrenheit.

Which list correctly orders the parts of an atom from heaviest to lightest in mass?
А
electron, proton, nucleus, neutron
В.
neutron, proton, nucleus, electron
С.
proton, neutron, electron, nucleus
D
nucleus, neutron, proton, electron
Answer:
nucleus, neutron, proton, electron
Explanation:
The list that correctly orders the parts of an atom from heaviest to lightest
in mass is as follows:
nucleus, neutron, proton, electron
The nucleus of an atom is composed of a tightly packed proton and
neutrons.
This makes the nucleus very dense and small. The nucleus are surrounded
by a negatively charged electron.
The nucleus contribute to most of the weight of an atom.
This makes the nucleus the heaviest.
The neutron is found in the nucleus of an atom. The neutrons are
electronically neutral. The neutron are slightly heavier than proton.
Therefore, the neutron is the second heaviest part of an atom.
The proton is found in the nucleus of an atom. They a positively charged.
The proton is the third heaviest.
The electron revolves around the nucleus and are very light. In fact the
nucleus contributes to 99.9 % of the weight of an atom. This shows how
light the electrons are.
Therefore, the order from the heaviest to the lightest is as follows:
nucleus, neutron, proton, electron
