What are cell organelles?

Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.

This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.

Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.

Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.

Thus, these were explanation of two cell organelles along with their explanation.

This may result from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called ____________ . This results from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons.

Answers

Answer:

Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.

Explanation:

In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

Neuromodulation is the release of chemicals (other than neurotransmitters ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called neuromodulators. Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is facilitation. This may result from either an increased amount of neurotransmitter in the synaptic cleft or an increased number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called inhibition. This results from either a decreased amount of neurotransmitter in the synaptic cleft or a decreased number of receptors on postsynaptic neurons.

When humans perspire, water, urea, and salts containing sodium are removed from the blood. Drinking water during extended periods of physical exercise replenishes the water but not the sodium. This increase in water dilutes the blood and may result in the concentration of sodium dropping low enough to cause a condition known as hyponatremia. Symptoms of hyponatremia include headache, nausea, and lack of coordination. Left untreated, it can lead to coma and even death. The body has a variety of feedback mechanisms that assist in regulating water and sodium concentrations in the blood. The kidneys play a major role in these mechanisms, as they filter the blood and produce urine. The best way to reduce the symptoms of hyponatremia would be to

Answers

Answer:

The best way to reduce the symptoms of hyponatremia is to replace the body's sodium.

Explanation:

As seen in the question above, sweating causes the body to lose water and salts, such as sodium. We know that the excess of sodium in the body is harmful, however, the lack of sodium is also harmful, and can cause hyponatremia.

The loss of water in sweating can be reversed with water intake, but the loss of sodium must be reversed with sodium intake and the best way to do this is by eating salty foods. Sodium is one of the components of the salt used in the preparation of foods. In that case, when an individual eats salty foods, after having lost sodium molecules in perspiration, he will be replacing the lost sodium.

1.) what is the optimal pH for pepsin? where is pepsin found?

2.) what is the optimal pH for salivary amylase? what substrate does it act on? where is it found?

Answers

Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0

The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2.  The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8.  around 7

Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

Which of the following steps happens first during transcription?
A. RNA polymerase reaches the end of the gene.
B. RNA polymerase reaches the beginning of a gene.
C. RNA polymerase pulls apart the double helix.
D. RNA polymerase produces mRNA from DNA.

Answers

The correct option for the given question about Genetic transcription is Option B) RNA polymerase reaches the beginning of a gene.

What is Genetic Transcription?It is one among the initial steps in the expression of genes. The transport of genetic information from DNA to proteins occurs sequentially through the processes of transcription and translation. During transcription, just one strand of DNA known as the template strand is replicated, and the resulting RNA is referred to as messenger mRNA.Transcription's primary goal is to create an RNA copy from a DNA sequence. The data required to encode a protein is carried by the RNA transcript.RNA polymerase is the key enzyme responsible for Genetic transcription.It creates a complementary RNA strand from single strand DNA.

Thus we conclude that during the first step of genetic transcription RNA polymerase reaches the beginning of a gene.
