Answer: The correct option is D

Explanation: The transport of glucose through the cell membrane is carried out by two types of proteins: transporters of glucose coupled to sodium, and proteins facilitating the transport of glucose. In both cases, the method of transport is the facilitated diffusion  through protein channels.

Compare and contrast the two cycles of matter
sertanlavr [38]

Answer:

The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms. 

They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition. 

Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.

DNA is composed of two strands, only one of which typically is used as a template for RNA synthesis. By what mechanism is the co
Andreyy89

To choose the strand the promoter acts to aim the RNA polymerase.

<h3>What does RNA polymerase do?</h3>

RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.

Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

insens350 [35]

Answer:

The weather and time do affect crime. The time of day, like late at night, is when most crimes occur. Since it's dark out, the criminal won't be seen as easily compared to during the day. Crime also spikes during warm weather since it seems to be easier for the criminal.
