Answer 1

Answer:

corrosionbases7It warys of how much concentration there is over 7

EXPLANATION:

plz can i get brainliest:)

Answer 2

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.

What is corrosion?

The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.

The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.

Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.

Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.

Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

How would adding finer particles to the sand affect porosity?

Answers

Explanation:

Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.

DNA binding protein [ Choose ]
Block the promoter region of a gene. [ Choose ]
Found associated with the gene encoding HCl production in a skin cell. [ Choose ]
Found associated with the genes encoding hemoglobin in a red blood cell [ Choose ]

Answers

Answer:

Increase transcription of a gene - Activator

DNA binding protein - Ribosome

Block the promoter region of a gene - Repressor

Found associated with the gene encoding HCI production in a skin cell - mRNA

Found associated with the genes encoding hemoglobin in a red blood cell - mRNA

Explanation:

Hemoglobin is an iron containing compound present in red blood cells which carries oxygen in the body. mRNA molecule contains exon coding for two proteins. mRNA molecule becomes associated with four to six ribosomes.

The statements on the left are correctly matched with the choices given on the right are:

Increase the transcription of a gene -------- Activator.DNA binding protein ------ Ribosome, Polymerases.Block the promoter region of a gene ------ Repressor. Found associated with the gene encoding HCl production in a skin cell -------- mRNAs.Found associated with the genes encoding hemoglobin in a red blood cell -------- mRNAs.

What do you mean by a Gene?

A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.

An activator is known to increase the transcription of a gene, while a repressor binds to the promoter region and inhibits the transcription process. The molecules of mRNA get associated with the gene HBA, HBB which encodes for hemoglobin in red blood cells. Ribosomes and polymerases are known for DNA binding protein.

Therefore, above are all the statements on the left that are correctly matched with the choices given on the right.

What is a Complementary DNA strand?

A complementary DNA strand may be defined as a type of DNA strand in which the series of the constituent molecules on one strand of the double-stranded structure is chemically similar to the sequence on the other strand.

According to Chargaff's rule, the complementary DNA strand is formed with the concept of base pairing, where Adenine is complementary to Thymine and cytosine is complementary to Guanine.

Due to this, A=T, G=C, G=C, T=A, C=G, A=T, G=C, G=C, and T=A. This matches option four given in the question.

Which organism obtains energy without directly depending on another organism

Answers

The organism that obtains energy without directly depending on another organism is a PLANT.

PLANTS are organisms which are capable of manufacturing their own food  through the process of photosynthesis.

Photosynthesis is defined as the process by which plants use low energy containing inorganic compounds (example carbondioxide and water) in the presence of sunlight, as energy, to produce high energy organic compounds such as sugar. These sugar are used as source of energy in the plant cells.

While animals are the organisms that directly depend on plants( another organism)

A 1.0-kb DNA fragment from the 5' end of the mouse gene is examined by DNA footprint protection analysis. Two samples are end-labeled with 32P, and one of the two is mixed with TFIIB, TFIID, and RNA polymerase II. Both samples are exposed to DNase I. The results are displayed below. The DNA exposed to proteins is run in the right-hand lane of the gel. Control DNA is in the left-hand lane.

Required:
What length of DNA is bound by the transcriptional proteins?

Answers

Answer:

Explanation:

Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.

As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.
