Which statement regarding DNA packing in eukaryotes is false?
A Tight DNA packing tends to promote gene expression
B) Euchromatin can be highly expressed
с
none of the answers are false
D
A nucleosome consists of DNA wound around a core of 8 histone
molecules.
E Highly compacted chromatin is generally not expressed at all.

Answers

Answer:

The correct answer is - A. Tight DNA packing tends to promote gene expression.

Explanation:

Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.

DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .

DNA packing decreases its transcription and hence no expression.

a. it contains proteins.
b. it contains cellulose.
c. it contains carbohydrates.
d. it is selectively permeable.

Answers

the answer is B

hope this helps!

The outer layer of the onion cell contains cellulose as compared to the skin cell, hence option B is correct.

What is cellulose?

3,000 or more glucose molecules make up the complex carbohydrate or polysaccharide known as cellulose.

The most prevalent of all naturally occurring organic substances, cellulose is the fundamental structural element of plant cell walls and makes up about 33% of all vegetable matter (it makes up 90% of cotton and 50% of wood).

The majority of all naturally occurring organic materials are composed of cellulose, which makes up roughly 33%, 50%, and 90% of all vegetative plants, cotton, and wood, accordingly.

Therefore, it decides the shape of the plant and enables the plant to grow upright, cellulose gives plant cells their stiffness, hence option B is correct.

Answers

Answer:

i. boron

ii. silicon

iii. germanium

iv. arsenic

v. antimony

vi. tellurium

vii. polonium

Explanation:

Elements that have appearance and properties of a metal but behave like non-metal in certain conditions are called semi-metals or metalloids. On the periodic table, they are found between metals and non-metals. Examples are astatine, polonium, tellurium, antimony, arsenic, germanium, silicon, boron.

Some of their properties that make them look like metals are:

i. They exist as solids at room temperature.

ii. They are shiny.

iii. They are ductile.

Some of their properties that make them look like non-metals are:

i. They are brittle.

ii. Not very good conductor of electricity compared to metals.

A new human species was found on a distant planet, whose genetic inheritance and process of reproduction is identical to that of humans on earth, however, their phenotypes are much different. You are tracking two phenotypes in this new species: eye shape and tail size. The single gene that controls eye shape (gene E) is unlinked from the single gene that controls tail size (gene T). Square eyes is the dominant eye shape and round eyes is the recessive eye shape. Long tail is the dominant tail size and short tail is the recessive tail size.
1. An individual of this new species is heterozygous for gene E and heterozygous for gene T. What is their genotype and phenotype? (Note, the ‘ / ‘ symbolizes the genotype of the two different homologs for a given chromosome, for example chromosome 5 homolog / chromosome 5 homolog, and ' ; ' separates different chromosomes for example 'chromosome 5 ; chromosome 8)

Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: antigens would be generated against the transplanted organ. rejection of the transplanted organ would still be expected. antibodies would be generated against the transplanted organ. rejection of the transplanted organ would not be expected. immunosuppressant drugs would be required to prevent transplant rejection.

Answers

Answer:

rejection of the transplanted organ would not be expected

Explanation:

Transplantation refers to 1-the movement of an organ/tissue/cells from one part of a person's body to another part, and 2-the movement of an organ/tissue/cells from one individual (donor) to another individual (recipient). An autograft is a type of transplant by which a patient receives his/her own tissue. For example, a skin autograft consists of a patch of skin that is removed from one area of the body and transplanted to another body region of the same individual. Skin autograft is a relatively common transplantation process used to repair wounds and restore skin function. In rats, the mechanism of skin autograft rejection has been reported as uncertain. Moreover, transplant rejection is a natural mechanism by which the immune system of a person does not recognize the transplant as its own, thereby attacking the transplanted organ/tissue. The autograft rejection reactions are relatively uncommon but they depend on the type of organ/tissue/cells to be transplanted.

Answers

Answer:

To remove impurities.

Explanation:

Minerals are processed in order to remove impurities from the minerals as well as getting clean minerals. If the minerals are not clean from impurities, it can't be used in the manufacturing of other products. Tailings are the materials that left over after the process of separating the mineral from the uneconomic fraction or residue of an ore. Tailing stored in water can be dangerous sources of toxic chemicals, such as heavy metals, sulfides and radioactive content that can adversely affected the biotic or living part of water.

How are primary and secondary succession similar and how are they different?

Answers

Answer:

They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed.

Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.

Answer:

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.

c. 1,4,6,7,10.
d. 2.4,5,8,10.
e. 2.4.5.7.9.

Answers

Answer:

The answer is "Choice e".

Explanation:

The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.
