Survival of all organisms is actualized due to ecological balance. Various species survive because favorable ecosystems were created. Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological balance is also important because it leads to the continuous existence of the organisms

In tomatoes, the following hypothetical pathway gives rise to different fruit colors. Y gene R gene Precursor substrate Intermediate substrate Product and lacks color and fruit is and fruit is yellow fruit is red green from chlorophyll Mutations in the genes for both of the enzymes produce lack-of-function, recessive alleles. What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual
Answer:
Explanation:
From the information given:
The analysis of the hypothetical pathway gives:
Y gene R gene
Green fruit → Yellow fruit → Red fruit.
If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:
RrYy × RrYy
The progenitors to undergo the segregation are as follows:
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
(red) (red) (red) (red)
Ry RRYy RRyy RrYy Rryy
(red) (green) (red) (green)
rY RrYY RrYy rrYY rrYy
(red) (red) (yellow) (yellow)
ry RrYy Rryy rrYy rryy
(red) (green) (yellow) (green)
Thus; the expected phenotypic ratio is:
= 9(red) : 3(yellow) : 4(green)
The expected phenotypic ratio is:
= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)

Use your completed Fossil Primate Chart (on pp. 393–394) to answer the following questions. What geographic region(s) have numerous fossil primate discoveries? Why might fossil primates be common in these places? Identify one geographic region that has few or no fossil primates. Why might fossil primates be rare here? Choose one strepsirhine-like fossil primate and one haplorhine-like fossil primate, and list at least two traits that distinguish them. What do these traits suggest about their classification and relationship to living primates? Choose any two haplorhine-like fossil primates and list at least two traits that distinguish them. What do these traits suggest about their classification and relationship to living primates?
Answer:
Africa, Madagascar, Asia, and the New World.
Explanation:
Africa, Madagascar, Asia, and the New World are the geographic regions have numerous fossil primate discoveries. Fossil primates to be rare in the temperate regions because only a small fraction of the primates that have ever lived has been preserved as fossils due to of climatic and geological conditions of the region. The strepsirhines like fossil primate containing wet-nosed primates, whereas haplorhines like fossil primate containing dry-nosed primates. These traits suggest that the living primates are evolved from these extent primates so that's why they are classified in the same phylum.

The missing coefficient for water is O6 in cellular respiration. Thus option A is correct.
What do you mean by aerobic cellular respiration?
Cellular respiration is up two types such as aerobic and anaerobic.
Aerobic Cellular Respiration is the process by which glucose is and oxygen are used to synthesize CO2, H2O and 36 ATP.
It occurs in the cytoplasm and mitochondria of the cell.
It has four steps such as Glycolysis occurs in the cytoplasm where breakdown of glucose occur and make 2 ATP.
The Intermediate Step take place in mitchondria where 3 carbon pyruvic acid molecules are converted to 2 carbon molecules.
Third step is the Kreb's Cycle occurs in the mitochondria where 2 ATP and Hydrogen ions are collected.
Finally, the Electron Transport Chain occurs in the cristae of the mitochondria make approximately 28-32 ATP.

Please do not copy and put in your own words.
Answer:
Various environment have unique environmental properties that make up matter.
Explanation:
Life on earth follows a cyclic nature, the energy that is received from the sun is recycled back to space. Similarly, various environments such as terrestrial, aquatic all are possessed different energy and have matter circulating through the ecosystem. Different factors like climate vegetation and other organisms help in the formation of soil which constitutes certain minerals. Similarly, the different region has diverse geologic settings that lead to the formation of diverse minerals such as limestone, sandstone, and resources like coal, petroleum, etc.What likely occurred in the nebula as a result of these changes?

Which of the following molecules are needed for photosynthesis?
Answer:
Carbon dioxide and oxygen is needed for photosynthesis, and water if you have the choice.
Explanation:
The molecules needed for photosynthesis are carbon dioxide and water.
What is photosynthesis?Photosynthesis is a process performed by green plants where they are able to synthesize their own food material from inorganic material using sunlight.
Photo - light and synthesis - to make. So the word photosynthesis means to "make something using light".
In green plants, the mesophyll cells of the leaves contain a green pigment called chlorophyll. It is present in the grana of their chloroplast. The chloroplast is thus the site for photosynthesis.
The inorganic matter required for photosynthesis is obtained from the environment. The carbon dioxide is obtained from the atmosphere by the stomata and water is absorbed by the roots.
The chlorophyll traps the sunlight which provides the energy for the hydrolysis of water and the formation of glucose and oxygen as a byproduct.
Therefore, the molecules required for photosynthesis are carbon dioxide and water.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

Consider the following population:
Blood Type A B AB O
Number of individuals 533 84 67 316
What is the frequency of the IB allele in this population?
Answer:
0.079
Explanation:
Using Hardy Weinberg equilibrium for blood group;
p² + 2pq + q² + 2pr + r² + 2qr = 1
where;
p = allele frequency for A
q = allele frequency for B
r = allele frequency for O
N(p² + 2pr) = the number of allele for type A people
N(q² + 2qr) = the number of allele for type B people
N(2pq) = the number of allele for AB people
N(r²) = the number of allele for O people
N(r²) = 316
r² = 316/1000
r² = 0.316
r = [tex]\sqrt{0.316[/tex]
r = 0.56
To find the frequency of the [tex]I^B[/tex] allele;
N(q² + 2qr) = 84
q² + 2qr = 84/1000
q² + 2qr = 0.084
where;
r = 0.56
q² + 2q(0.56) = 0.084
q² + 1.12q = 0.084
q² + 1.12q - 0.084 = 0
Using the quadratic formula:
[tex]=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]
where;
a = 1, b = 1.12, c = -0.084
[tex]=\dfrac{-(1.12) \pm \sqrt{(1.12)^2-4(1)(-0.084)}}{2\times 1}[/tex]
[tex]=\dfrac{-(1.12) \pm \sqrt{1.2544-(-0.336)}}{2}[/tex]
[tex]=\dfrac{-(1.12) \pm \sqrt{1.5904}}{2}[/tex]
[tex]=\dfrac{-(1.12) \pm 1.261}{2}[/tex]
[tex]=\dfrac{-(1.12) + 1.261}{2} \ \ OR \ \ \dfrac{-(1.12) - 1.261}{2}[/tex]
[tex]=\dfrac{0.141}{2} \ \ OR \ \ \dfrac{-2.381}{2}[/tex]
[tex]\simeq 0.079 \ \ OR \ \ -1.1905[/tex]
Since our value can be negative; then the frequency of the [tex]I^B[/tex] allele in this population is 0.079.
