zubka84 [21]

Answer:

C. Inorganic Fertilizers

Explanation:

No inorganic fertilizers on earth contain cycle participating carbon. The only carbon containing fertilizer is organic Urea (NH2CONH2). This is because plants are never deficient in organic carbon availability. The inorganic fertilizers only deal with their mineral need and that;s why they don't participate in carbon cycle.

Transcriptionally inactive regions of the genome are typically heavily methylated. True or false?
polet [3.4K]

The answer is true.

DNA methylation is a process by which methyl groups are added to the DNA, more precisely to its nucleotides adenine or cytosine (they are methylated) via enzymes called DNA methyltransferases. This process as a result can change the activity of a DNA. For example, if DNA of gene promoter is methylated gene transcription is repressed. The opposite process is DNA demethylation.

So, DNA methylation is an epigenetic mechanism meaning that gene activity can be changed and inherited that way, but the sequence  of DNA remains the same.

Match each tool with its influence on science
Nadusha1986 [10]

Answer:

xray - allows scientists to see dense structures

Microscope - view things that cannot be seen with the naked eye

Telescope - stars, planets and black holes

Ultrasound - see inside the body in real time

Explanation:

Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.

Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.

Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.

Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.

Kobotan [32]

Answer:

Rats and Humans both live on land during all life stages.

Explanation:

I think this because rats don't live in water or anything like that during their lifetimes. Humans also don't live in water during their lifetimes. So that is how I know that they share living on land during all life stages characteristic.
