Answer:

The correct answer is option C. "Uncovered meat that had contact with air".

Explanation:

In 1668, the Italian scientist Francesco Redi performed a celebrated experiment to prove that maggots are not spontaneously created by placing fresh meat in each of two different jars: one opened and one covered with a cloth. Redi used an uncovered meat that had contact with air as a control, expecting that flies will come in and the maggots will be developed as they do in nature.

Forensic entomology identifies the fauna on a dead body to make predictions about the death. C) ants, mites, and beetles frequent the body<u> 3-17 days</u> after death.

<h3>What is forensic entomology?</h3>

Forensic entomology is the forensic branch that studies the cadaveric fauna associated with a dead body to make scientific conjectures.

Cadaveric fauna usually includes different forms of invertebrate species and their stages of development. There is a predictable sequence in which different species arrive at the dead body and inhabits it, and this sequence depends on the time the individual has been dead and the decomposition state of the body.

The species inhabiting the body and their developmental stage can be used as significant data to estimate the time of death, the region, and the circumstances under which the individual died.

Stages of decomposition depend on the region, but we can make this generalization,

  • 1-3 days ⇒ adult flies and eggs, and a few larvae

  • 3-5 days ⇒ bacteria and other microorganisms act. The decomposing body produces gasses that inflate the carcass. Larvae penetrate the body, release the gasses, and the carcass collapses.

  • 5-15 days ⇒ Maggots, flies, ants, and beetles have already reached the dead body.

  • 15-25 days ⇒ Most flesh is already consumed, and the body is in the advanced stage of decay. Although the number of invertebrates is low, the diversity of species is great. There are carpet beetles, ants, skipper flies, and mites.

  • 25-50 days ⇒ Almost dry body with no flesh. Some arthropods are still feeding on it.

  • >50 days ⇒ Bones

<u>Note</u>: Remember that these are approximations and might vary according to the region and environmental conditions, such as temperature, precipitation, humidity, etcetera.

According to this information, we can say that ants, mites, and beetles frequent the body in warmer climates between <u>3 and 17 days</u>. Option C.

Explain how triose phosphate is produced and used in the chloroplasts of a plant.
vampirchik [111]
LIRs take place in stroma of chloroplast; and they produce carbohydrates; CO2 is fixed; to RuBP (a 5-C compound); by Rubisco; to form an unstable 6-C compound; which splits into 2 molecules of glycerate-3-phosphate; LDRs produce ATP and NADPH; of which ATP provides energy to reduce glycerate-3-phosphate; to triose phosphate; whilst NADPH provides hydrogen required to do so; Some 3-C sugars go to form hexose sugars; others make more RuBP; (Calvin cycle);
