Interferons are produced by the body cells to protect uninfected cells from viral invasion. So, the correct option is (D).
What are Interferons?Interferons (IFNs) are defined as a group of signaling proteins which are released by host cells in response to the presence of many viruses. A virus-infected cell releases interferons that cause nearby cells to mount their anti-viral defenses.
These are a group of proteins called cytokines which are produced by white blood cells, fibroblasts, or T-cells as part of the immune response to viral infection or other immune triggers. The proteins' name comes from their ability to interfere with the production of new virus particles.
These substances are produced by the body cells to protect uninfected cells from viral invasion.
Thus, Interferons are produced by the body cells to protect uninfected cells from viral invasion. So, the correct option is (D).

Place the bones of the upper appendicular skeleton in order as they would be encountered in anatomical position as you moved distally.
Proximal phalanx Il Proximal
Humerus
Ulna
Middle phalanx II
Scapula
Clavicle
Distal phalanx II
Capitate
Metacarpal I
Lunate Distal
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.
What would have a greater detrimental effect: the moon stops rotating or the Earth
stops rotating? Defend your answer.
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.

Now assume that while studying the species, another researcher suggests that changes in land-use in the habitat of axis deer in Texas may be creating food shortages for the species and that the habitat is only capable of supporting approximately 2500 animals. Does this change your analysis of the situation
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.

Most of the traits expressed in a person's phenotype are determined by is Phenotype.
What is Phenotype?Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe."
It can therefore refer to anything from a common attribute, like height or hair color, to the presence or absence of a disease. It is also an observable type of an organism.

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.
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.

Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
O True
O False
Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
Some of the principal human activities responsible for biodiversity loss are
the uncontrolled use of unrenewable resources, overexploitation of renewable resources; land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures; the unplanned advance of cities, and opening of new roads to connect those cities.All of them involving
deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity.With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
The respect for nature, People´s education at different levels to care and protect wildlife, Interest in keeping ancestral knowledge, Planning and previous environmental impact studies, Policies to control human activities, Caring involved government.If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.

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.

Streptococcus pneumoniae causes all of the following EXCEPT ________. Group of answer choices meningitis. lobar pneumonia. bronchopneumonia. necrotizing fasciitis. bacteremia.
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.

Mitochondria have a permeable inner membrane and an impermeable outer membrane. Mitochondria regulate apoptosis. Mitochondrial DNA is packaged with histones. The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.
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.
