Answer:
B. 0 m
Explanation:
The graph given is a position - time graphical model of the motion of a body.
The y-axis denotes the position of the body and the x- axis is the time taken.
To solve this problem, since the velocity of the motion is constant and no acceleration, we trace up the point 6s on the x-axis and find the y-axis equivalent.
Completing the graph, the point lies on 0m. At 0m, the object would have traveled for 6s.Answer:B. 0 m

Who said all animals were made of cells
Answers
Answer:
Theodor Schwann said all animals were made of cells.Explanation:
I hope l helped ❤❤❤It was proposed by Theodor Schwann that animals were made of cells.
Although Robert Hooke (who coined the term “cell”) first noticed them in 1695, it wasn’t until 1839 that Theodor Schwann (author of “The Theory of Cells”) and Mattias Schleiden first proposed the idea that all living things are made up of cells.
An animal cell is an eukaryotic cell with a plasma membrane surrounding it. The cell has a membrane-binding nucleus and a liquid cytoplasm and does not have a cell wall like a plant cell. Animal cells are part of the kingdom Animalia.
Theodor Schwann coined the term cell theory and claimed that all living things are made up of cells and that cells were the smallest and most fundamental component of all living things.

Is a lion a producer, herbivore, consumer or a omnivore
Answers
Answer:
Lions are primarally carnivors because they only consume meat. Herbivores are animals that only consume plant like rabbits and Ominvores are animals that consumer both like humans., so consumer
Explanation:
A lion is a consumer. In ecological terms, a consumer is an organism that obtains its energy and nutrients by consuming other living organisms.
Lions are carnivores, which means they primarily feed on other animals. They are top-level predators in their ecosystems, preying on a variety of herbivores, such as zebras, wildebeests, and antelopes.
As consumers, lions play a vital role in regulating prey populations and maintaining ecological balance in their habitats. They are not producers or herbivores since they do not engage in photosynthesis or primarily eat plants.
Additionally, lions are not omnivores, which are organisms that consume both plants and animals.

Which of the following distinguishes why deer populations have increased?
The amount of predator animals has decreased.
Fewer hunters are culling the population of deer.
The amount of other grazing animals has decreased.
Fewer cattle are allowed to graze on open grasslands.
Answers
Answer:
The most correct option is the first option
Explanation:
A deer is an herbivorous animal that is usually preyed upon by many wild carnivorous animals like lions, tigers and leopards. Hence, when the population of these wild predatory carnivorous animals reduce, the population of the deer would increase because fewer of them would them would be killed by predators despite them (the deers) reproducing.
Note that a predator is an animal that feeds upon another animal (referred to as prey) of lower "strength".
Alleles can be described as 1. dominant 11. recessive III. codominant IV. partially dominant V. incompletely dominant O A. I, II, III, and V only OB. I and II only OC. I, II, and Ill only OD II, III, and V only
Answers
Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).
There is a considerable amount of chemical energy stored in a tall tree. For instance, the wood could be burned to make a great deal of heat.
From where does the chemical energy come?
Answers
Answer:
The correct answer is - the sun.
Explanation:
When a plant is in initial stages there isgradual increase in the mass of the plant which become later as a tall tree by the process of the phostosynthesis as it increase the storage of glucose or sugar in the tree. The mass of the tree by glucose storage is due to the carbon molecules of CO2 moleules.
Photosynthesis is the process that involves the trapping of the light come from the sun which is then converted in the cheical energy in the form of the glucose or the sugars.
The chemical energy present in the tall trees comes from the Sun.
• Through the process of photosynthesis, the tall trees convert energy from the Sun, that is, light energy into the chemical energy.
• The majority of this energy is stored in the trees in the form of compounds known as carbohydrates.
• When animals consume trees and its components, they consume and absorb some of this energy, that is, stored as chemical energy into the compounds protein and fats.
Thus, the green plants and trees are the source of energy, that is, used for various purposes. Through the process of photosynthesis, the light energy coming from the Sun gets converted into the chemical energy that gets stored as carbohydrates.

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?
Answers
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.

Indicate whether each of the following statements about the effect of this uncoupler is true or false; if false, briefly justify in one or two sentences. (4 points total) (a) The rate of oxygen consumption will decrease. (b) The cell will switch from glucose oxidation to fatty acid oxidation. (c) ATP synthase will still be able to create ATP. (d) Lactic acid fermentation will increase sharply.
Answers
Answer:
(a) The rate of oxygen consumption will decrease.
Explanation:
The rate of oxygen consumption will decrease due to the Potassium cyanide which inhibits both utilization of oxygen by the cell as well as ATP production. Cytochrome performs an important function in the mitochondria of the cell which is the production of ATP. Cyanide binds to the cytochrome and inhibits the ATP production that is performed by mitochondria of the cell. So Potassium cyanide decreases the rate of oxygen consumption in mitochondria.

a)ATP Synthase
b)Proton Pump
c)NADPH
d)ADP
Answers
ATP synthase is a protein attached to the thylakoid membrane that helps synthesize ATP each time an H+ ion exits the thylakoid. Therefore, option A is correct.
What is ATP synthase?The enzyme that produces ATP molecules is called ATP synthase. ATP synthases create ATP from its precursor, ADP. The cristae and inner membrane of mitochondria, the thylakoid membrane of chloroplasts, and the plasma membrane of bacteria all contain these enzymes.
It is a multi-component complex that crosses the mitochondrial inner membrane, the cell's power plants.
In order to manufacture ATP more effectively, the curvature of the mitochondrial inner membrane must be created by the interaction of the enzyme complex with fatty molecules. Therefore, option A is correct.

The toxin produced by the intestinal bacterium Vibrio cholerae induces excessive diarrhea by stimulating the excretion of NaCl and large amounts of water into the intestine. The mechanism by which cholera toxin acts is ADP ribosylation of: a. the GTP-bound form of Gai, locking it in the active conformation. b. the GDP-bound form of Gas, locking it in the inactive conformation. c. the GTP-bound form of Gas, locking it in the active conformation. d. Gaq, inhibiting its GTPase activity. e. Gai, decreasing its affinity for GDP.
Answers
Answer:
c. the GTP-bound form of Gas, locking it in the active conformation.
Explanation:
The reason is that the toxin created by the enteric intestinal bacterium Vibro cholerae triggers an exorbitant amount of diarrhea by inducing the excretion of NaCl and enormous amounts of water into the bowel. The mechanism by that epidemic cholera toxin acts is ADP ribosylation of the Gs alpha monetary unit. This implies that G[tex]\alpha[/tex]s macromolecule protein exploits NAD, therefore protecting it within the active conformation.
What would happen in a cell if the DNA was destroyed completely or changed in any way?
Answers
Answer:
If the DNA of a cell is destroyed completely the cell would die i.e. cease to exist. A change in the DNA (germ-line mutation) would change the structure and/or functions of proteins in the cell.
Explanation:
The central dogma theory indicates that DNA is replicated to produce daughter cells. These daughter cells are then transcribed into mRNA (micro RNA) which are in turn translated into structural and functional proteins.
If the DNA is totally destroyed, no mRNA is formed and by implication, such a cell has no proteins. Now proteins are practically the "godfather" molecules in any cell, they maintain the selectively permeable cell membrane's integrity, they form the structural component of most cellular organelles, they are essential for transport of essential/toxic substances in/out of the cell, etc.
Looking at these functions, cessation of protein production is equivalent to cessation of cell life (apoptosis if DNA destruction is not stimulated externally).
A mutation (change in DNA) changes which protein is produced. A practical indication of this is when a single point mutation in hemoglobin produces sickle cell anemia!!
