State the two components of natural capital.
Mademuasel [1]

Answer:

I think

Abiotic natural capital comprises subsoil assets (e.g. fossil fuels, minerals, metals) and abiotic flows.

Biotic natural capital or ecosystem capital consists of ecosystems, which deliver a wide range of valuable services.

In a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.

<h3>What is active transport?</h3>

The movement of dissolved molecules into or out of a cell via the cell membrane, from a low concentration region to a high concentration region is referred to as active transport.

These particles use the energy released during respiration to move against the concentration gradient.

Thus, in a situation where the concentration of solute is low inside the cell, the cell will be referred to as a hypotonic cell. The transport in this type is referred to as active transport.

Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural sel
Elza [17]
Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.
Hope this helped a little!

All cells as we can say they work through their proteins. The work of proteins is being characterized by their sub-atomic capacity, contribution to a specific natural process and limitation inside. Segments of protein work which are being characterized by the correct synthesis, adaptation of proteins and structure which are being scrambled in the DNA area which is another name is called locus encoding the protein.
New proteins are being produced by the procedure of protein combined with organic cells, which are adjusted by the loss of protein cell through corruption. The RNA which is duplicated in protein hereditary data is encoded in DNA atom which is being created in the core known as RNA or mRNA. mRNA encodes data which is for solitary protein and is considered little in estimate by contrasted with DNA atom. This makes work easier for mRNA particles to leave the core passing through some small openings called atomic pores.
It leaves the core and goes straight to the cytoplasm. mRNA interferes with cell structure referred to as ribosome and fills in as cells contrasting agent within the procedure of protein union. Ribosome comprises of ribosome RNA particles or rRNA and proteins which are sorted out into two subunits.
When a small subunit is being accused of tRNA and corrosive amino acid methionine experiences mRNA which begins to begin flag.
When beginning succession AUG is found then the codon for corrosive amino methionine where substantial subunits join the little one to frame and hole ribosome where now protein amalgamation starts.
Following the codon downstream of AUG codon, the elongation of tRNA and amino corrosive enter to the ribosome. tRNA with wrong amino corrosive and wrong anticodon enters ribosome it is rejected because it can not base pair with mRNA.
The ribosome then propels on triplet and amino corrosive and tRNA enters the ribosome and method is then rehashed. In the termination, the ribosome achieves all the stop codons. Post-translation modification alludes to the covalent and leads to large enzymes change of proteins following biosynthesis of protein PTM happens in any progression within the life cycle of protein.
Protein in PTMs can be reversed depending upon the idea of change for example kinases phosphorylate of protein at a certain amino corrosive side chains phosphatases hydrolyzes phosphate where they gather and expel it from protein.

In the absence of tryptophan, _____.
GenaCL600 [577]

Answer: A

Explanation:The Trp operon is responsible for synthesis of the amino acid trytophan when it is not available in the cellular environment.

When the tryptophan is plentiful, a repressor protein binds to two molecules of tryptophan.

Thiss repressor-tryptophan complex binds to the trp operator. This binding prevents the binding of RNA polymerase, so the operon is not transcribed, and no new trptophan is produce.

On the other hand, when tryptophan levels are reduced, the inactive repressor will not bind the tryptophan operator so the operon is transcribed.

Regulation of the trp operon is determined by the concentration of tryptophan; when adequate tryptophan is present in the growth medium, there is no need for tryptophan biosynthesis.

Transcription is turned off when a high concentration of tryptophan is present, and is turned on when tryptophan is absent. The regulatory signal is the concentration of tryptophan itself.

Therefore in the absence of tryptophan, the inactive repressor cannot bind trpO, so operon gene transcription occurs.
