A sample of peptide of unknown sequence was treated with trypsin to produce the following smaller peptides:
1) Met-Val-Ser-Thr-Lys
2) Val-Ile-Trp-Thr-Leu-Met-Ile
3) Leu-Phe-Asn-Glu-Ser-Arg
Another sample of the same peptide was treated with chymotrypsin and gave the following smaller peptides:
1) Asn-Glu-Ser-Arg-Val-Ile-Trp
2) Thr-Leu-Met-Ile
3) Met-Val-Ser-Thr-Lys-Leu-Phe
What is the sequence of the original peptide?

Answers

Answer 1

Answer:

The sequence is >> Met-Val-Ser-Thr-Lys-Leu-Phe-Asn-Glu-Ser-Arg-Val-Ile-Trp-Thr-Leu-Met-Ile,  or abbreviated M-V-S-T-K-L-F-N-E-S-R-V-I-W-T-L-M-I

Explanation:

Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.

Which is abiotic?
tree sap
O insect
O sunlight
O tree stump

Answers

Answer:

Sunlight is abiotic. Abiotic is a non living thing

Sunlight is an abiotic factor. Therefore, the correct statement is option C.

What do abiotic elements consist of?

Sunlight is an inanimate element of the environment, making it an abiotic one. Insects and tree sap are both living things, and a tree stump is a decomposing piece of the environment that was once alive.

Abiotic elements are the ecosystem's non-living parts. They include natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements. In contrast, biotic factors include live species, including plants, animals, fungi, and bacteria.

Sunlight is a crucial abiotic component of ecosystems because it fuels photosynthesis and influences the development and behavior of living things. It also affects weather patterns and climate, which may have a big influence on ecosystems.

Therefore, sunlight is an abiotic factor including natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements.

Which of the following ways are leftover neurotransmitters cleaned up if they
have not been accepted by the postsynaptic neuron?
Pick 2
the neurotransmitters are broken down in the synapse

the postsynaptic neuron absorbs the neurotransmitters

The presynaptic neuron absorbs the neurotransmitters

the neurotransmitters are built up to create a new neuron

Answers

Answer:

The correct answer is -

the neurotransmitters are broken down in the synapse

The presynaptic neuron absorbs the neurotransmitters

Explanation:

The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.

This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.

what are the factors that make the planet habitable​

Answers

Answer:

Safe distance (like the earth) from the sun, starts surrounding the planet have to be stable, should not have a very low mass.

It must rotate on its axis and revolve.

It should have a molten core.

It should hold an atmosphere.

The planet (earth ) is habitable based on these factors :

Temperature Right chemical  ( like  water and oxygen )protection from solar radiationdistance from the sun

The planet ( earth ) is habitable because of some certain factors that cannot be found on other planets . such as The temperature of the planet ( earth ) is on an average of 58.62°F. which is the right temperature for human and plant habitation.

The presence of freshwater and oxygen in the atmosphere makes the planet habitable and also other necessary chemicals

The magnetic field of the Earth protects the Earth from high levels of solar radiation and this makes the earth safe and habitable for humans.

The distance of the earth from the sun also makes it possible for life to exist on planet earth

Hence we can conclude that the factors that make the planet habitable are :Temperature , Right chemical  ( like  water and oxygen ), protection from solar radiation, distance from the sun

Describe what is happening with light and matter in photosystem II and Photosystem I.

Answers

Answer:

Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.

It captures photons and uses the energy to extract electrons from water molecules. These electrons are used in several ways. First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.

Which statement best explains why BaCl2 is an ionic compound?
O A. BaCl, has a net charge of -2.
O B. The neutral atom Ba gains 2 electrons.
O C. BaCl, has a net charge of +2.
OD. The neutral atom Cl gains 1 electron.

Answers

Answer:

D. The neutral atom Cl gains 1 electron.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Barium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.89. There is large difference is present. That's why two valence electron from barium is transfer to the chlorine. Barium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.  There are two valence electron lost by barium while chlorine required one electron to complete the octet thus two chlorine atoms are bonded with one barium atom. Each atom of chlorine carry -1 charge while one barium atom have +2 charge.

Homeostasis Review - List some things in living things that need to be regulated

Answers

Answer:

Homeostasis The tendency to resist change in order to maintain a stable, relatively constant internal environment

Explanation:

The body maintains homeostasis for many factors. Some of these include body temperature, blood glucose, and various pH levels.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

Feedback loops

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values. An example of a negative feedback loop is body temperature regulation.

Example of negative feedback loop

Example of negative feedback loop

The maintaining of body temperature is an example of a negative feedback loop. When body temperature increases, there are mechanisms that work to decrease temperature, and vice versa.

In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Example of positive feedback loop

Negative feedback loop=

Feedback loop that acts to oppose the triggering stimulus

Positive feedback loop= Feedback loop that amplifies the starting signal

The H₂O, or water is exiting the cell, and the result is shriveled up red blood cells.

In a hypertonic solution, there is a greater concentration of solute outside the cell and a greater concentration of water inside the cell.

The water will diffuse through osmosis from high to low concentration, so the water moves out of the cell.
