Polymers are many moments strung together. They are linked together by dehydration reactions. (Remove water)
Answer:
A. They are constantly moving. I think.
Explanation:
Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Answer: Transcription - A
Explanation:
This problem is talking about the lac operon and the gene expression of lac operon. If the gene is turned off, then transcription, the generation of mRNA won't occur.
Answer:
The haploid (n) number would be 23 chromosomes found in the gametes, reproductive cells of sperm and ova. For the organism in this example the diploid (2n) number is 12 making the haploid (n) number would be half of that or 6 chromosomes
