The Offspring produced by a cross between two given types of plants can be any of the three genotypes denoted by A, B, and C. A theoretical model of any of the three genotypes denoted by A, B, and C should be in the ratio 1:2:1. For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded. Do these data contradict the genetic model
Complete question:
The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.
Genotype Observed frequency
A → 18 individuals
B → 55 individuals
C → 27 individuals
Do these contradict the genetic model?
Use a 0.05 level of significance.
Determine the chi-square test statistic.
Answer:
Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.
Explanation:
Available data:
Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individualsSo, let us first state the hypothesis:
H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25% H₁ = the population is not in equilibriumNow, let us calculate the number of expected individuals, according to their expected ratio.
4 -------------- 100% -------------100 individuals
1 --------------- 25% -------------X = 25 individuals A
2 -------------- 50% -------------X = 50 individuals B
1----------------- 25%--------------X = 25 individuals C
A B C
Observed 18 55 27 Expected 25 50 25 (Obs-Exp)²/Exp 1.96 0.5 0.16(Obs-Exp)²/Exp
A) (18 - 25)²/25 = 49/25 = 1.96
B) (55 - 50)² / 50 = 25/50 = 0.5
C) (27 - 25)²/25 = 4/25 = 0.16
Chi square = X² = Σ(Obs-Exp)²/Exp
∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A. E are the Expected individuals: 10 in each chamberX² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62
Freedom degrees = 2
Significance level, 5% = 0.05
Table value/Critical value = 5.99
X² < Critical value
2.62 < 5.99
These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.

Answer:
Uses hydrolases -lysosome
Uses the enzyme catalase- peroxisome
Is one of the main sites of fatty acid breakdown- peroxisome
Combines with endosomes to digest ingested matter- lysosome
Capable of converting hydrogen peroxide to water and oxygen- peroxisome
Destroys engulfed bacteria- lysosome
Main role is metabolism- both lysosome and peroxisome
Digestive interior is acidic- lysosome
Proteins are derived from the endoplasmic reticulum- Peroxisome
Explanation:
The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.
Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.
Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.

3. Catabolic, Anabolic, and Metabolism
What do you mean by metabolism?Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes.
Moreover, it is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.
Hence, if your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs. So, the correct options are A and C.
What are Indoor pollution?Indoor air pollution, which can be as much as ten times worse than outside air pollution, is indeed the degradation in indoor air quality caused by hazardous chemicals and other elements. This is because enclosed rooms encourage the accumulation of possible contaminants more than do open ones.
The main contributors to indoor air pollution include: Bioaerosols, building materials, and combustion Although radon, asbestos, pesticides, toxic substances, organic volatile compounds, and environmental tobacco smoke are all regarded as serious indoor pollutants in industrialised countries, developing countries are primarily affected by the combustion byproducts of biomass fuels.
The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs.

A. gravitational pull
B. eye
C. updraft
D. fog
Plz Help!!! God Bless You
Winds blowing in opposite directions form a cylinder that might get tipped up by a supercell’s updraft.
What do you mean by updraft?Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.
The definition of an updraft is a strong upward current of air. When a big gust wind comes along and catches on the umbrella on your outside table from underneath, knocking your umbrella and table over with its power, this big gust of wind is an example of an updraft.
When warm, moist air moves upward in an updraft, puffy cumulus clouds may form in the atmosphere. The moisture in the air condenses into water droplets as it rises. The cloud will continue to grow as long as warm air from below continues to rise.

Explanation:
I took the test :D
In a flock of birds, parents can raise small clutches on their own but can increase their clutch size if they have a helper. You want to see if altruistic behavior is likely to spread. To do this you observed a male bird that stayed at his birth nest for a year to help raise the offspring of his father and his stepmother (the original mother died) and then built his own nest the following year. You calculated direct fitness (cost) for the male bird by counting the number of offspring he produced in one year and multiplied it by ½ due to the relatedness between parents and offspring. To calculate his indirect fitness (benefit), you took the total number of offspring produced in his birth nest by his father and stepmother when he assisted them and multiplied it by ½. To determine if this altruistic behavior would spread you subtracted the cost from the benefit to determine whether it was greater than 1. What did you do wrong
Answer:
The mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2Explanation:
The relatedness between ; Mother, father, daughter and son = 0.5 ( 1/2 ) which is included in the direct fitness category ( For the MALE bird )
The relatedness for the Half brother and Half sister of the male bird = 0.25 ( 1/4 ) ( indirect fitness )
hence applying Hamilton's rule
Relatedness = rb - c > 0
where b = benefit , c = cost
∴Total fitness = ∑ direct fitness + ∑ indirect fitness
= 0.5x + 0.25y
hence the mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2Fibroblasts can be placed on thin sheets of silicone rubber. Under normal circumstances, fibroblasts exert sufficient tension on the rubber so that it visibly wrinkles. Explain how the ability of fibroblasts to wrinkle rubber would change if the cells were treated with a permeable form of C3 transferase, a toxin (from the bacterium Clostridium botulinum) that covalently modifies an amino acid in Rho. The modification renders Rho unable to bind to proteins that it would normally bind to when active.
Answer:
C3 transferase decreases Rho activity and contractility by decreasing the number of stress fibers and thus also reducing wrinkles
Explanation:
Rho protein is a small GTPase, i.e., an enzyme that binds GTP to hydrolyze it to GDP, which is known to mediate the formation of stress fibers and focal adhesion. Rho protein is involved in diverse cellular functions including, among others, adhesion, motility, and division by reorganization of the actin cytoskeleton. The bacterial toxin C3 transferase derived from Clostridium botulinum is able to lock Rho in an inactive state. C3 transferase adds an ADP-ribose to Rho, thereby leading to the accumulation of a Rho-guanine nucleotide dissociation inhibitor (GDI) complex in the cytoplasm. In consequence, C3 transferase functions to decrease contractility by blocking Rho activity, decreasing the number of stress fibers and leading to a reduction in wrinkles.
