Answer:

Explanation: Protein digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas. During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.

Explanation:

Answer:

Interphase - There are 3 subphases called - G1 , S and G2 . In these subphases, DNA material is duplicated, and essential proteins for cell division are formed.

Prophase - the nuclear envelop and nucleolus disappears and condensed DNA forms chromosomes that are short in size.

Metaphase - the form of two sister chromatids are arranged in the middle of the metaphase/equatorial line. Two centrioles are found at two poles of the cell which initiate the formation of spindle fibers.

Anaphase - spindle fibers are formed and can be observed. These fibres attach with the kinetochore present in the centromere of chromosomes and these chromatids now start separated by pulling and pushing force of spindle fibers in opposite poles

Telophase -  chromatids reach at destination pole and then nuclear envelop starts creating again in both poles. Nucleolus reappears and now in a cell two nucleus are found.

Answer:

1000 MM individuals; 2000 MN individuals; 1000 NN individuals

Explanation:

The Hardy-Weinberg principle states that, under certain conditions, the frequency of alleles and genotypes in a sexually reproducing population will remain constant over generations. The Hardy-Weinberg assumptions include random mating, sexual reproduction, and the absence of evolutionary forces such as mutation, natural selection, and genetic drift (as in the example above). Under these conditions, the frequency of alleles and genotypes in a population will not change and tend to the equilibrium. In this case, under Hardy-Weinberg equilibrium, the frequency of the M allele or 'p' must be equal to 0.5, and the frequency of the N allele or 'q' must be equal to 0.5 (i.e., the sum of all allele frequencies in the population must be equal to 1). Moreover, the frequencies of the genotypes will be p², 2pq, and q² >> p² (MM genotype) = (0.5)² = 0.25; q² (NN genotype) = (0.5)²  = 0.25; and 2 x p x q (MN genotype) = 2 x 0.5 x 0.5 = 0.50. In consequence, under Hardy-Weinberg equilibrium, in a population of 4000 diploid individuals (8000 alleles), we have

- 4000 M alleles (M = 0.5) and 4000 N alleles (N = 0.5);  

- 1000 MM individuals [p² >> (0.5)² = 0.25]; 2000 MN individuals (2pq >> 2 x 0.5 x 0.5 = 0.5) and 1000 NN individuals [q² >> (0.5)² = 0.25].

Answer:

1. False

2. False

3. True

Explanation:

1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood

Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure increases not decrease

The statement is false

2. A large compliance is indicative of being highly sensitive to changes in pressure

Compliance, C = ΔV/ΔP

From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small

Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false

3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation

Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true

Answer:

La oscuridad de una mancha solar es solamente un efecto de contraste; si pudiéramos ver una mancha tipo, con una umbra del tamaño de la Tierra, aislada y a la misma distancia que el Sol, brillaría unas 50 veces más que la Luna llena. Las manchas están relativamente inmóviles con respecto a la fotosfera y participan de la rotación solar. El área de la superficie solar cubierta por las manchas se mide en términos de millonésimas de hemisferio solar visible.

The correct energy flow during aerobic respiration is ATP, Glucose, and cells. Thus, the correct option is B.

Aerobic respiration may be defined as the process of conversion of glucose into carbon dioxide, water, and energy via the intermediate product of pyruvate in presence of air.

The release of energy in aerobic respiration is found to be greater as compared to anaerobic respiration.

This released energy is immediately used to synthesize a molecule called ATP via glucose that fuels the cells for metabolic activities.

Therefore, the correct option for this question is B.

I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.

Explanation:

Answer:

c. T state is low affinity and R state is high affinity.

Explanation:

Hemoglobin (Hb) is a multimeric protein molecule that transports oxygen from the lungs to the body's tissues in red blood cells. Hb exists in two quaternary states: 1- a T-state or deoxygenated conformation, which is referred to as 'deoxyhemoglobin'; and 2-a R state or fully oxygenated conformation, which is referred to as 'oxyhemoglobin'. The sequential model of cooperativity states that the conformation of a multimeric protein changes with each binding of a ligand, thereby sequentially changing its affinity for the ligand (i.e., cooperativity is dependent on ligand-induced). In consequence, this model states that the conformational state and affinity of Hb monomers change as they bind to oxygen.

Answer:

The citric acid cycle is the final common oxidative pathway for carbohydrates, fats and amino acids. It is the most important metabolic pathway for the energy supply to the body.

Answer:

Species are as specific as you can get. It is the lowest and most strict level of classification of living things. The main criterion for an organism to be placed in a particular species is the ability to breed with other organisms of that same species.

The sympathetic nervous system is responsible for the mouse's physiological state.

The nervous system divides into the central nervous system and peripheral nervous system.

In the central nervous system, we have the brain and the spinal cord.

The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:

-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.

-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.

In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting

R = Vesicle velocity / step size

Explanation:

The rate of ATP hydrolyzation can be explained  by relating ΔG ( Gibbs free energy)  and Q using this equation :  ΔrGo + RT ln(Q).   where ΔrGo = standard  Gibbs energy change.

Answer:

The greenhouse effect is a natural process that warms the Earth's surface.

When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

The absorbed energy warms the atmosphere and the surface of the Earth causing green house effect .

Answer:

The greenhouse effect occurs when radiation from a planet's atmosphere warms the planet's surface to a higher temperature than it would be without the atmosphere. Radiatively active gases emit energy in all directions from a planet's atmosphere.
