satela [25.4K]

When plants do not get enough nitrogen, they are unable to produce amino acids (substances that contain nitrogen and hydrogen and make up many of living cells, muscles and tissue). Without amino acids, plants cannot make the special proteins that the plant cells need to grow.

Identify two general ways chemical mutagens can alter dna.
gavmur [86]
1) compound mutagens can go about as base analogs 
Analogs are perceived by DNA polymerase and consolidated into DNA set up of nucleotides and after that reason change by base-matching in a way that varies from the undifferentiated from nucleotide. For instance, 5-BrdU can be consolidated inverse An amid replication and after that combine as a C amid the following round of replication, making a TA CG change. 
2) substance mutagens can synthetically adjust base. 
Compound adjustment of bases changes their base-blending properties to such an extent that an altered purine will base-match with the wrong pyrimidine and the other way around. For instance, EMS is an alkylating operator that proselytes guanine to O6-methylguanine, which base-sets with T to make a GC to AT progress

Steps of photosynthesis​
son4ous [18]
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

When resistant bacteria multiply, what do they pass on to the next generation?
andrew11 [14]

Answer:

Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.

The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.

Hope this helps :)

Explain how and why water travels through the four Earth systems as it moves through the water cycle.
Komok [63]

Explanation:

It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
