Why is it necessary for the pancreas to secrete a high ph (basic) solution into the small intestine?

It is necessary for the pancreas to secrete a high pH solution into the intestine in order to neutralize the acidity of the processed food particles [chyme] that are passed into the intestine and to provide a suitable pH for the enzymes in the intestines that will act on the processed food particles.

Answer:

To neutralize the pH of food from the stomach and then go to the duodenum

Explanation:

The pancreas is one of the organs in the human digestive system. In general, the function of the pancreas in the body is to produce hormones and enzymes to destroy food in the stomach. The pancreas is behind the abdominal cavity with a length of 18-25 cm and has an elongated shape, resembling a fish.

The function of the pancreas is divided into two, namely exocrine and endocrine functions

1. exocrine function

When food has been successfully digested in the stomach and gradually towards the duodenum. Duodenum will produce a hormone called the cholecystokinin hormone. This hormone serves to give stimulation to the pancreas to produce various enzymes and fluids contained in the form of pancreatic gums that help the digestive process. Examples are the salivary glands, sweat glands, and digestive glands.

Various types of enzymes produced, namely lipase enzymes, trypsinogen enzymes, amylase enzymes, pancreatic carbohydrase enzymes, and NaCHO3 fluid.

The pancreas can be said to have the function of exocrine organs having a role in the digestive process to break down complex molecules into simpler molecules. Besides the pancreas also serves to neutralize the pH of food that comes from the stomach to then go to the duodenum.

2. Endocrine function.

The function of the pancreas as an endocrine organ is carried out by the islets of langerhans found in the pancreas. Langerhans Island has four kinds of cells, each of which produces different hormones.

Langerhans is spread throughout the pancreas and is rich in blood vessels. 1-2 percent of the pancreas is composed of Langerhans cells. The cells that are in the langerhans, include alpha pancreas cells, pancreatic beta cells, pancreatic gamma cells, and pancreatic delta cells.

The main task of the pancreas as an endocrine is to regulate blood sugar levels and regulate food absorption.

Answer:

Chordates

Explanation:

The notochord is a flexible, rod like supporting structure, running dorsally for almost the whole length of the body. This is a distinctive feature of a chordate / animals with a back bone (vertebral column) Such animals belong to phylum Chordata.

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.

lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase) that metabolize activities of cholinergic neurotransmitters e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites transmits action potential to the neuromuscular junction is called presynaptic neuron. While neuron that transmit action potential away from the neuronal synaptic junction, or from the neuromuscular junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called post synaptic neuron.

The more negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to continuous excitatory activities of cholinergic neurotransmitters on the receptors at the postsynaptic neuron, and the more action potential

vlada-n [284]

Answer:

frequencies of light-colored mice ≅ 0.74

frequencies of dark-colored mice ≅ 0.26

frequencies of light-colored mice ≅ 0.13
frequencies of dark-colored mice ≅ 0.87

q² = 0.74
p² = 0.02
2pq = 0.24

q² = 0.13
p² = 0.4
2pq = 0.46

The dark-colored fur seems to have the greatest overall selective advantage

Dark lava, that changed the color of the substrate, from light to dark.

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.
