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.which organelles can be found in both plant and animal cells

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.

In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
Glucose + Oxygen ------> ATP + Carbon dioxide + Water
C6H12O6 + 6O2 ----------> 36ATP + CO2 + H2O
The chemical equation for cellular respiration shows that plants cycle matter because oxygen and glucose that is produced by the plants is used by the human body for the generation of energy in the form of ATP molecules, water and carbondioxide gas.
This carbondioxide gas is released by animals which is used by the plants in order to make their own food during the process of photosynthesis so we can conclude that the chemical equation for cellular respiration shows that the plants cycle matter.

Cells in many-celled organisms...
A. All look the same
b. All have the same structure
c. are often quite different from each other
d. are the same size in every part of the organism
Answer:
c. are often quite different from each other
Explanation:
Multicellular organisms - composed of several different cells: Cells in these organisms differ in relation to the function to be performed.
The cells in these organisms are growing, developing, and reproducing.
The cells differ in shape, size, and role they have in the organism.
In the group of multicellular organisms are animals (Animalia), plants (Plantae), and fungi (Fungi).
Cells in many-celled organisms are often quite different from each other. Therefore option C is correct.
In many-celled organisms, such as animals and plants, cells can be specialized for specific functions, leading to their differentiation and diversification.
Different types of cells have distinct structures and perform specific tasks within the organism.
For example, nerve cells (neurons) are specialized for transmitting electrical signals, muscle cells for contraction, and blood cells for carrying oxygen and nutrients.
This specialization allows for efficient division of labor, where each cell type contributes to the overall functioning of the organism.
The diversity of cell types and their functions is a fundamental aspect of the complex organization and functioning of multicellular organisms, contributing to their overall biological complexity and adaptability.
Therefore option C are often quite different from each other is correct.

1. **In the procedure shown below, a calcium chloride solution is mixed with a sodium sulfate solution to create the products shown. Which of the following is illustrated by this activity?
a. The law of conservation of mass
b. The theory of thermal equilibrium
C. The law of conservation of energy
d. Newton's 2nd Law
The reaction follows the law of conservation of mass since the mass remains same before and after the reaction. Therefore, option (A) is correct.
What is the law of conservation of mass?According to the principle known as the rule of conservation of mass, during a chemical reaction, mass can neither be created nor destroyed. When coal is burned, for instance, the atom of carbon that it contains transforms into carbon dioxide. The mass of the carbon atom remains constant even as it transforms from a solid structure to a gaseous state.
The study of chemical reactions, as well as their generation, places a significant emphasis on the principle of mass conservation. Scientists are able to make accurate forecasts regarding the amounts of products that will be produced from a certain reaction if they are aware of both the amounts of reactants and their identities.
Thus, in the above reaction the mass is conserved and option (A) is correct.

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)

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
