Explanation:
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?
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.

Answer:
Experimental Vaccine Herpes Vaccine = D
Attenuated = B
Purified macromolecule Vaccine = B
Recombinant-Vector Vaccine = A
Inactivated or Killed = C
Diphtheria Vaccine = A
Explanation:
A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.
Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).
The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Consider a hepatocyte (liver cell) carrying out the oxidation of glucose under aerobic conditions. Potasstum cyanide, a potent inhibitor of the enzyme cytochrome c, is administered. 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.
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.

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
What is DNA replication?It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.
Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.
The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.
In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.
Thus, the correct statement is the second one, that is, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

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.

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.
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.
__________ is a protein attached to the thylakoid membrane that helps synthesize ATP each time a H+ ion exits the thylakoid.
a)ATP Synthase
b)Proton Pump
c)NADPH
d)ADP
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.

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.
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".

Right atrium of the heart
Explanation:
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.

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
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).
