Which of the following is a test forensic scientists might use for chemical analysis?
Size of insect
O Color pattern on insect
Range map of insect
DNA extracted from crop

Answers

Answer 1

This kind of chemical analysis can be carried out using spectroscopy of atomic absorption and plasma-atom inductively coupled emission spectroscopy.

In the simplest words, what is spectroscopy?

Spectroscopy is the study about how light and also other types of electromagnetic radiation are taken and emitted by materials. In a manner similar to how a prism divides light it into rainbow of colors, it entails splitting light (or more accurately, electromagnetic phenomena) into its individual wavelengths (a spectrum).

What is the spectroscopic principle?

The fundamental idea behind all absorption spectroscopy is to expose a sample to an electromagnetic field and then see how it reacts. Typically, the response is measured in relation to the radiation wavelength.

The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.

Answers

Answer:

The correct statements are -

Mitochondria are the sites of aerobic metabolism

Mitochondria regulate apoptosis.

Explanation:

Mitochondria is one of the eukaryotic cell organelles that are double membrane and plays important role in the different function of the cell. The main and major function of the mitochondria is aerobic metabolism that includes aerobic respiration where glucose converts into carbon dioxide and water with releases a high amount of energy in the form of ATP.

These also plays important role in programmed cell death or apoptosis it activates apoptosis by releasing protein by the inner and outer membrane. The inner membrane of mitochondria is impermeable and allows through transporters and outer membrane non-specifically permeable to low molecular substances. Mitochondrial DNA lacks histone protein and  TFAM, an HMG-like protein involved in the process.

Ulna
Middle phalanx II
Scapula
Clavicle
Distal phalanx II
Capitate

Lunate Distal

Answers

Answer:

Clavicle- Scapula- Humerus- Ulna- Lunate- Capitate- Metacarpal I- Proximal phalanx Il- Middle phalanx II- Distal phalanx II.

Explanation:

The upper appendicular skeleton starts with the clavicle, which is between the sternum and the scapula. Then we have the scapula, which is between the clavicle and the humerus. Following the humerus, we have the ulna and radius, which are in the forearm. Then we have the carpals bones, which are in two rows; the proximal row has the pisiform, the triquetrum, the lunate, the scaphoid; and the distal row has the capitate, the trapezium, the trapezoid, and the hamate. Then we the metacarpals, the proximal phalanges, the middle phalanxes, and the distal phalanxes.

When we have to place the bones from proximal to distal, like in this case, we have to locate the bones that are closer to the middle line of the body and then the ones that are far from it.

II. Support the body
III. Protect the internal organs
IV. Make the eggs

I and II
II and IV
I and IV
II and III

Answers

Answer:

c

Explanation:

I and IV are the functions of the reproductive organs in animals.

What are Reproductive organs?

The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.

The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).

The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.

Therefore, I and IV are the functions of the reproductive organs in animals.

Does this change your analysis of the situation

Answers

Answer:

Yes.

Explanation:

Yes, this change of conditions also change the analysis of the situation because the analysis is related to the environmental conditions. When the environmental condition for an organisms changed so it also change its presence in that environment. If there is plenty of resources such as water, food and space for living, the population of that organism will be higher in that region while on the other hand, if this organisms is moved to a place where the resources such as water, food and space is scarce then it will leads to decrease in population of that organisms so we can say that change in conditions also bring change in our analysis.

Answers

Answer:

The correct answer is ''necrotizing fasciitis.''

Explanation:

Streptococcus pneumoniae belongs to the Streptococcaceae family. It is a Gram positive bacterium, normally facultative anaerobic, catalase negative, immobile, with an oval shape, surrounded by a capsule (does not present Lancefield antigens) and is usually grouped into chains of two (diplococcus) or more bacteria. It can give rise to a wide range of manifestations, among them, the most frequent but the least serious are upper respiratory tract infections, such as: otitis media, sinusitis, etc; while the less frequent but the most serious are: pneumococcal pneumonia, invasive pneumococcal disease, meningitis and septicemia. Necrotizing fasciitis is a rapidly progressive infection that affects the skin, subcutaneous cellular tissue, superficial and deep fascia, causing tissue necrosis and severe systemic toxicity, which, if not treated in a timely manner, is invariably fatal. The most common germs in immunocompetent people are Streptococcus pyogenes and Staphylococcus aureus. In patients with a defined gateway in the skin, the incidence of S. aureus is high. Deep necrotizing processes can be mono- or polymicrobial. In monomicrobial processes, pathogenesis is largely mediated by toxins (FN by S. pyogenes, FN by S. aureus, clostridial myonecrosis). In polymicrobial processes there is a synergism between aerobic and anaerobic germs. The most common aerobes are Enterobacteriaceae, Streptococcus group A, and S. aureus. The predominant anaerobes are Peptostreptococcus spp, Bacteroides fragilis group, Prevotella sp, Porphyromonas spp and Clostridium sp. Streptococcus pneumoniae belongs to the Streptococcaceae family.

What would have a greater detrimental effect: the moon stops rotating or the Earth
stops rotating? Defend your answer.

Answers

Explanation:

when the moon stops rotating around the earth

earth will be crush down because it is the pull of the moon gravit on the earth that hold our planet earth in the place.

A greater detrimental effect would have been caused if the moon stops rotating or the Earth stops rotating. This is because the rotating celestial bodies exert some kind of gravitational pressure in order to make them in the exact locations.

What happens when the earth stops rotating?

If the earth stops rotating, this inhibition of motion suddenly causes the momentum that would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

If the moon stops rotating or the earth stops rotating then the other celestial body disrupts down. Due to this, the pull of the moon's gravity on the earth or the pull of the earth's gravity on the sun holds each other in their exact location.

g The primary digestive enzyme released by the stomach, as well as many of the digestive enzymes created and released by the pancreas, are initially released in their inactive form and must be activated after the fact. For one, explain how this activation occurs (and how it differs between the enzymes from these two organs), and for another, explain why this paradigm of releasing inactive enzymes is so important, physiologically.

Answers

Answer: The release of inactive form of enzyme is important because when the enzyme will active on its release it can digest the organs and glands from where it had been released to support the function of the enzyme only when it is required to be released and promote its functioning at the target site the enzyme is required to be released only in an inactive state.

Explanation:

Pepsin is a an enzyme secreted by the stomach cells in the inactive form that is called as pepsinogen. The function of the pepsinogen is to digest protein in the food. The activation of pepsin requires an acidic pH maintained by the hydrochloric acid in the gastric secretion of stomach. The   pancreatic cells secrete enzyme trypsinogen which is activated into trypsin when it enters into the duodenum of the small intestine by the enzyme enteropeptidase.
