The high specific heat of water help maintain the temperature of the Earth by heating and cooling more slowly than land or air. Thus, the correct option is A.
What is the specific heat of water?The specific heat of an object is the amount of heat which is required to increase or raise the temperature of unit mass of that particular substance through one degree celsius. Specific heat is represented by the symbol 'c'. Its unit in SI system is Joule /(kg °C) and in CGS is cal / (gm °C).
The high specific heat of water helps in regulating the rate at which air changes its temperature, which is why the temperature of the planet change between different seasons is gradual rather than sudden, especially the geographical locations near the ocean.
Therefore, the correct option is A.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?
Answer:
Smaller and slower axons are those related to temperature, itching and pain.
Explanation:
As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.

b. Acetylcholine diffuses across the synaptic cleft before binding to its receptor, which is located on the _____
c. When the membrane potential reaches ________an action potential spreads across the sarcolemma due to the opening of ___________
d. In response to acetylcholine binding, ________ move into the muscle fiber causing the membrane potential to rise.
Answer:
a). Voltage-gated Ca2+ channels
b). the motor end plate
c). Threshold, voltage-gated Na channels
d). sodium ions
Explanation:
a). The voltage-gated [tex]Ca^{2+}[/tex] channels are the key transducers of the membrane potential that changes into a intracellular [tex]Ca^{2+}[/tex] transients which initiates the physiological events. When the action potential makes a contact with axon terminal, the voltage-gated [tex]Ca^{2+}[/tex] channels opens.
b). The acetylcholine is the main neurotransmitter of the parasympathetic nervous system. It helps in blood vessels dilation, muscle contraction, and perform many more functions.
It diffuses with the synaptic cleft that is located on the motor end plate of the nervous system.
c). The membrane potential is also known as the membrane voltage or the transmembrane potential. When it recaches the threshold, the voltage-gated Na channels opens to spread the action potential across sarcolemma.
d). The sodium ions in case of acetylcholine binding moves to the muscle fiber due to which the membrane potential rises.

Consider the factors that affect muscular strength. Read each scenario and then identify each label into the appropriate category based on whether each would result in a stronger or weaker muscle contraction.
a. Potassium accumulate in the sarcoplasm
b. Increase in muscle belly circumference
c. Lesser proportion of motor neurons to muscle fibres
d. Begin contractions with muscle already 50% contraction
e. Lower sarcoplasm pH
f. Increased stimulus frequency.
g. Circular arrangement of muscle fascicles
h. increased requirement.
Answer:
1. Weaker contraction:
a. Potassium accumulate in the sarcoplasm
d. Begin contractions with muscle already 50% contraction
e. Lower sarcoplasm pH
g. Circular arrangement of muscle fascicles
2. Stronger Contraction
b. Increase in muscle belly circumference
c. Lesser proportion of motor neurons to muscle fibres
f. Increased stimulus frequency.
h. increased requirement.
Explanation:
Sarcoplasm refers to the cytoplasm of muscle cells which contains ATP, enzymes, and a variety of ions, including potassium (K+). The negative potential required during muscle activity is produced from the disequilibrium of ionic concentrations (mostly Na+ and K+) across the membrane, which is generated through Na+/K+ ATPase pumps. During contraction, a muscle shortens, and thus its circumference increases. The generation of lactic acid is known to lower pH in the sarcoplasm and thus hinder the force and power development of the muscle fibers. Muscle fascicles can be arranged in concentric rings, it is a common pattern in sphincter muscles that modulate the opening and closing of orifices (which have weak contractions). A motor unit refers to a single efferent neuron and all of the muscle fibers it modulates. Each individual muscle fiber is innervated by one motor neuron, whereas a single motor neuron can innervate many muscle fibers. Finally, higher intensity/frequency are known to induce stronger muscular contractions, but also produce a stronger decline in force and cause more rapid muscle fatigue.

The bacterium Methylophilus methylotrophus can use methanol and ammonia for protein synthesis. The glutamate dehydrogenase gene from E. coli was introduced into M. methylotrophus using recombinant DNA techniques. Under high ammonia conditions, the introduction of the glutamate dehydrogenase gene into M. methylotrophus resulted in an increase in protein yield. Select the statements that are reasonable explanations for the increased protein yield in the modified M. methylotrophus. Glutamate dehydrogenase catalyzes the formation of glutamate and glutamine in a two-step process. Both glutamate and glutamine play a key role in amino acid synthesis, thus an increase in levels of glutamate and glutamine increase protein synthesis. Glutamate dehydrogenase has a low affinity for NH^+_4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH^+_4, when the concentration of NH^+_4 is high. Glutamate dehydrogenase has a high affinity for NH^+_4, thus the rate of glutamate synthesis increases exponentially under high ammonia conditions. Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.
Which statement accurately identifies the order of tissues pictures left to right in the microscopic image?
a) Epithelial cells, smooth muscle, connective tissue
b) Connective tissue, epithelial cells, smooth muscle
c) Epithelial cells, connective tissue, smooth muscle
d) Connective tissue, smooth muscle, epithelial cells
Answer:
The correct answer is - d) Connective tissue, smooth muscle, epithelial cells.
Explanation:
The connective tissues are the tissue layers that protect the outside of arteries and veins. The thick outermost layer of a tunica adventitia and other, made of connective tissues.
The middle layer that has tunica media that s made up of outer connective and smooth muscles in the inner or middle and in the innermost layer is made up of epithelial layer.
As per the image given the statements that describe the tissues from the left to right in a microscopic image are connective tissue, smooth muscles, and epithelial cells.
The connective tissues support and protect and give stricture. The smooth muscles are involuntary non straighter muscles. The epithecal cells that line the surface of the body.Hence the option D is correct.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. A pure bred plant with green spherical shaped seeds is crossed with a pure bred plant with yellow dented shaped seeds. State the phenotype and genotype for the parent plants p1 and p2
Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.

All different combinations were catalogued in the beginning of the century by a South African herdmaster. This work inspired the Nguni Cattle Register, a compilation of terms to describe in full a Nguni cow or bull. The cattle are medium-sized, with bulls weighing between 500 and 600 kg,[3] while cows weigh between 300 and 400 kg.
In a Nitrogen metabolism study, the following data were obtained over the test period:
Nitrogen consumed 175 grams
Total Fecal N 35 grams
Metabolic Fecal N 10 grams
Total Urinary N 80 grams
Endogenous Urinary N 10 grams
Calculate:
a. Apparent Nitrogen digestibility (%)
b. True Nitrogen digestibility (%)
c. Nitrogen Balance (g)
d. Apparent Nitrogen Retention (%)
Answer:
a. 80%
b. 86%
c. 60 g
d. 34.29%
Explanation:
From the given information:
The apparent nitrogen digestibility (AD) is the ratio of the difference between the consumed nitrogen and fecal nitrogen to the consumed nitrogen.
Mathematically:
[tex]AD = \dfrac{consumed \ nitrogen - fecal \ nitrogen }{consumed \ nitrogen }[/tex]
[tex]AD = \dfrac{175 -35 }{175}[/tex]
AD = 0.8
To percentage, the apparent Nitrogen digestibility = 80%
b. True Nitrogen digestibility is calculated by the formula:
[tex]=\dfrac{consumed \ nitrogen - (fecal \ nitrogen -metabolic \ fecal)}{consumed \ nitrogen}[/tex]
[tex]= \dfrac{175 -(35-10)}{175}[/tex]
[tex]= \dfrac{175 -25}{175}[/tex]
= 0.86
= 86%
c. Nitrogen Balance = consumed Nitrogen - Fecal nitrogen - total uninary
Nitrogen Balance = (175 - 35 - 80) grams
Nitrogen Balance = 60 g
d. Apparent Nitrogen Retention (ANR) is computed as follows:
[tex]ANR = \dfrac{(consumed \ nitrogen-fecal\ nitrogen - total \ uninary )}{nitrogen \consumed }\times 100\%[/tex]
[tex]ANR = \dfrac{(175-35- 80 )}{175 }\times 100\%[/tex]
[tex]ANR = \dfrac{(60 )}{175 }\times 100\%[/tex]
ANR = 34.29%
