A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls look at the picture! I will mark whoever sounds best the brain! Ty!
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

Why are both prereading and postreading strategies used?
O to review meaning
O to increase reading speed
O to enhance comprehension
O to memorize text
Answer:
A. to review meaning
Explanation:
To review meaning are both prereading and postreading strategies used.
What is Prereading?
Before attentively reading a text (or a chapter of a text) from beginning to end, pre-reading is the process of scanning the material to identify essential concepts. sometimes known as surveying or previewing.
Pre-reading gives you an overview, which can help you read more quickly and effectively. Examining (and considering) chapter titles, summaries, headings, subheadings, study questions, and conclusions are typical pre-reading activities.
Students can use pre-reading tactics to anticipate what they will read or hear by considering what they already know about a particular topic. Teachers can focus on a book's organization, teach new vocabulary or other concepts, look for the primary idea, and provide students a reason for reading or listening before they even begin to read any material.
Therefore, To review meaning are both prereading and postreading strategies used.

Once the light organ is colonized, the squid no longer takes in Vibrio fischeri or other bacteria from the environment. Explain how a sufficiently large population of bacteria can be maintained in the light organ to produce light.
Answer:
Due to suitable conditions.
Explanation:
Large population of bacteria can be maintained in the light organ to produce light by providing suitable conditions for growth and development in the organ. The luminescent genes are off when the organ has low cell density while on the other hand, when the density of cell is high in the light organ the luminescent genes automatically turned on and light up the organ. These Vibrio fischeri needs habitat and food for their growth and survival which is provided by the squid. If there is sufficient food for the squid, the population of Vibrio fischeri increases in the light organ.

how does independent assortem increase genetic diversy
Answer:
Genetic diversity is increased by independent assortment (genes are inherited independently of each other) and crossing over during meiosis. During meiosis, chromosomes (which are found in pairs) swap large portions of their molecules, causing genetic material to be mixed between them.
Explanation:
How do you think molecules of food rearrange when they react with oxygen in the cells of your body?
Answer:
In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.
Explanation:
The glucose and oxygen atoms are rearranged into carbon dioxide and water molecules during aerobic respiration. Being an exothermic chemical reaction, this process releases energy as it goes along.
What is aerobic respiration?A chemical reaction that converts carbohydrates into energy using oxygen (sugars). also known as oxidative metabolism, aerobic metabolism, and cell respiration.
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise.
As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.
During aerobic respiration, glucose and oxygen atoms are rearranged into carbon dioxide and water molecules. As it proceeds, this process releases energy since it is an exothermic chemical reaction.
Thus, molecules of food rearrange when they react with oxygen in the cells of your body.

3) Select the reasons why global warming might still occur even if greenhouse-gas emissions drastically decrease.
Answer:
If the emission of greenhouse gases were stopped, global warming would still happen due to the gases that are already in the atmosphere and the constant deforestation.
Explanation:
Greenhouse gases are the biggest creators of global warming. This is because these gases cause holes in the ozone layer, which protects the planet from the sun's rays. These holes cause the sun's rays to reach the earth's surface with greater intensity, promoting global warming.
Trees are able to absorb these gases, decreasing their concentration in the atmosphere and preventing them from degrading the ozone layer. However, the constant deforestation has reduced the number of plants and the remaining amount on the planet cannot cope with the constant emission of these gases. In this case, even if the emissions of greenhouse gases were ended, the amount of these gases in the atmosphere would still be very large. Plants were slow to absorb all these gases, which would not prevent global warming from happening.
