Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.
Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.
STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.
Answer:
B. Use the polymerase chain reaction (PCR) to make multiple copies of the DNA.
Explanation:
The scientist is to analyze a small sample of DNA, the most useful step to start this would be first the use of polymerase chain reaction to make various copies of that DNA sample. PCR is essential and quick process that gives a lot of copies within few hours. It uses the sample or target DNA, according to which the primers are designed. Taq polymerase and DNA polymerase are also used in the process, it consist of various cycles in which copies are made. There are three basic steps 'Denaturation', 'annealing', and 'extension'.
The phase after ovulation (release of an egg) is called luteal phase. The stimulating follicle hormone (fsh) and luteinizing hormone (lh) are produced in the pituitary.
The FSH promotes the growth of an egg in the follicle while the LH facilitates its release from the follicle. Once the egg is released, the two hormones decrease, resulting in the rise of estrogen and progesterone.
Answer:
Carbon Monoxide
Carbon forms two important gases with oxygen: carbon monoxide, CO, and carbon dioxide, CO2
