Biological weathering facts

Biology

Biological Weathering<span>Biological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things called </span>lichens<span> (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler. </span>

How are meiosis and<br> mitosis different?
goldenfox [79]

Answer:

Mitosis provides two diploids (2n) somatic cells that are genetically indistinguishable from each other and the primary parent cell, whereas meiosis creates four haploids (n) gametes that are genetically individual from each other and the original parent (germ) cell.

List ten factors which can be involved in regulating bacterial gene expression (includes specificity and level of expression). "
nirvana33 [79]

Answer:

At least 6 were provided:

1. Transcription.

2. Chromatin domains.

3. mRNA degradation.

4. RNA transport.

5. Translation.

6. Post-transcriptional modification.

Explanation:

Chromatin domains.

Changes to the epigenome can result in changes to the structure of chromatin and changes to the function of the genome.

Transcription.

During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript.

Post-transcriptional modification.

is a set of biological processes common to most eukaryotic cells by which an RNA primary transcript is chemically altered following transcription from a gene to produce a mature, functional RNA molecule that can then leave the nucleus and perform any of a variety of different functions in the cell.

RNA transport.

mRNA is created during the process of transcription, where the enzyme RNA polymerase converts genes into primary transcript mRNA (also known as pre-mRNA). This pre-mRNA usually still contains introns, regions that will not go on to code for the final amino acid sequence.

Translation.

In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide.

mRNA degradation.

Different mRNAs within the same cell have distinct lifetimes (stabilities). In bacterial cells, individual mRNAs can survive from seconds to more than an hour. However, the lifetime averages between 1 and 3 minutes, making bacterial mRNA much less stable than eukaryotic mRNA.

The process of respiration is essential in the oxygen/carbono dioxide carbon cycle. Respiration remoces From the atmosphere and
irakobra [83]

Answer:

Respiration is a process in which energy is released due to the breakdown of glucose molecules with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP). In respiration process, carbondioxide is released in the atmosphere and oxygen is used for breakdown of food. This carbondioxide is used by the plants in the process of photosynthesis and oxygen is released in the atmosphere which is again used by animals for respiration.

Which lists types of materials from most conductive to least conductive?
Alinara [238K]

Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.

Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.

Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.

Thus, B) is the right answer.
