Why is it necessary to have a constant input of energy into an ecosystem?
IrinaK [193]
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.

What must eukaryotes do to initiate transcription of a gene?
Mars2501 [29]

Answer:

c)Recruit the transcription factors and RNA Polymerase that compose the pre-initiation complex.

Explanation:

Transcription leads to formation of RNA from DNA. The process is carried out by RNA Polymerase which forms a RNA strand according to the template DNA strand.

It starts by the formation of pre-initiation complex. RNA Polymerase along with transcription factors binds to the promoter region of DNA and forms the pre-initiation complex. Generally the eukaryotic promoters have a sequence called as TATA box where the transcription factors bind first. Eventually RNA polymerase also binds to the region and the DNA strands separate starting the transcription process.

A cell from a tissue culture has 38 chromoses after mitosis and cytokinesis one daughter cell has 37 what might occurred to caus
ankoles [38]

Answer:

occurred an aneuploidy (monosomy)

Explanation:

Aneuploidy can be defined as a chromosomal aberration in which the chromosome number is abnormal. In an aneuploidy, the number of total chromosomes in daughter cells is not an exact multiple of a haploid set, by either gaining or losing chromosomes during mitosis. Aneuploidies are common in cancer cells and in different types of chromosome disorders. Moreover, monosomy is a type of aneuploidy in which daughter cells have a single chromosome copy instead of the two copies found in diploid cells. For example, Turner syndrome is a monosomy caused by the loss of the X chromosome.
