Answer:
They are: substrates, template, primer and enzymes. Four deoxyribonucleotide triphosphates (dNTP's) are required for DNA synthesis (note the only difference between deoxyribonucleotides and ribonucleotides is the absence of an OH group at position 2' on the ribose ring). These are dATP, dGTP, dTTP and dCTP.

Estos son dATP, dGTP, dTTP y dCTP.

Answer:
Chloroplasts are the ’solar energy plants’ of a cell – they convert light energy into chemical energy
This chemical energy may be either ATP (light dependent) or organic compounds (light independent)
Only photosynthetic tissue possess chloroplasts (e.g. is present in leaves but not roots of plants)
Chloroplasts are thought to have once been independent prokaryotes that were internalised by eukaryotes via endosymbiosis
They have a double membrane structure (due to vesicular coating as part of the endocytotic process)
They have their own DNA (circular and naked) and ribosomes (70S)
Their metabolic processes are susceptible to certain antibiotics
The structure of the chloroplast is adapted to the function it performs:
Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation
Grana – thylakoids are arranged into stacks to increase SA:Vol ratio of the thylakoid membrane
Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption
Stroma – central cavity that contains appropriate enzymes and a suitable pH for the Calvin cycle to occur
Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency

The answer for the food chain would be answer B.
<span>Anton van Leeuwenhoek, </span>who designed and built the first microscope, also discovered microbes such as protozoa and bacteria from a drop of pond water. He also viewed bacteria taken from his teeth scrapings. He was also the first to discovered blood cells and human sperm cells.
Answer:
1. In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.
2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.
3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.
