Answers

Answer 1
Eh I don't think so look at squirrels
Answer 2
If an animal does not have four legs, It still can be a mammal. The definition of a mammal is a warm-blooded vertebrate animal that possesses hair or fur, secretion of milk by females for the nourishment of the young, and (typically) the birth of live young. By this definition, both whales and porpoises are mammals, and they do not have four legs.

What are the effects of invasion of privacy?

Invasion of Privacy Damages and Recovery. ... This article will briefly describe some of the available remedies and consequences in invasion of privacy cases. Bear in mind that not all states recognize all four of the privacy torts, and even those that do differ with respect to the types of damages and recovery they award.

The invasion of privacy can lead to psychological distress, a loss of trust, and control over personal information, as well as potential blackmail or identity theft.

The invasion of privacy can have several far-reaching effects on individuals and society. The act of infringing on someone's personal space or accessing their confidential information without consent can lead to psychological distress, diminished trust in digital platforms, and a loss of control over personal information. Most notably, when privacy settings are compromised, private information can fall into the wrong hands, potentially leading to identity theft, blackmail, or even personal harm.

When it comes to the correlation between sharing information online and privacy, a significant concern is how much control users have over their data. More often, users may not be aware of the extent to which their information is tracked or shared. As social media platforms and websites collect personal data, they create privacy risks that can impact a person's current or future employment and even social relationships. This collection of personal information without clear consent or understanding from individuals raises concerns about the erosion of privacy rights online.

Lipogenesis is the breaking down of stored fat when blood glucose levels are low.

Answers

The answer is false. Lipogenesis is the triglyceride synthesis, wherein lipogenesis occurs only when ATP or glucose levels are over the needed substance. The opposite action of lipogenesis is lipolysis, wherein stored fats are being broken down into glycerol and fatty acids, which results as fuel for the body.

What determines the viscosity of magma? What else determines whether a volcano will erupt violently or calmly 
AnswerThe two main factors that influence how a volcano will erupt are viscosity and gas content. Both are related to the composition of the magma. Hawaiian volcanoes tend to erupt basalt, which is low in viscosity and low in gas content (about 0.5 weight percent). The gas that is present can readily escape and little pressure builds up in the magma. At the other extreme, rhyolite magmas are very viscous and can contain a lot of gas (up to 7-8 weight present). As the magma moves into the vent and the pressure drops, the gas wants to escape. The magma is very sticky and resists the expansion of the gas bubbles. Ultimately, enough bubbles grow and expand to blow the magma into ash size fragments and eject them violently into the atmosphere.

Answers

The viscosity of magma is determined by its silica content. Basalt magma, on the one hand, which is often of low viscosity, has a low silica content of approximately 50% or less. Rhyolite magma, on the other hand, has high viscosity due to the high silica content of approximately 70% and more.

Gas content and temperatures of the magma are the other factors that determine an explosive or nonexplosive eruption. High temperatures and high gas content (coupled with high viscosity) cause violent explosions.


Final answer:

The viscosity of magma is influenced by its composition. Low silica magma has low viscosity, while high silica magma has high viscosity. Gas content also plays a role, with low gas content leading to calm eruptions and high gas content leading to violent eruptions.

Explanation:

The viscosity of magma is influenced by its composition. Magma with a low silica content, such as basalt, has low viscosity, meaning it is more fluid and flows easily. On the other hand, magma with a high silica content, such as rhyolite, has high viscosity, meaning it is sticky and doesn't flow easily.

Another factor that determines how a volcano will erupt is the gas content of the magma. Basaltic magmas typically have low gas content, allowing the gas to escape easily and resulting in calm eruptions. In contrast, rhyolitic magmas can have high gas content, and the sticky magma resists the expansion of gas bubbles, leading to violent eruptions.

A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytosine. For the complimentary strand of DNA, which would complete the proper base pairing?

Answers

Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!

Toxins like α-amanitin are used for research in much the same way as null mutants−to disrupt a process and see what happens when it no longer works. researchers examined the ability of α-amanitin to inhibit different rna polymerases. they purified rna polymerases i, ii, and iii from rat liver, incubated the enzymes with different concentrations of α-amanitin, and then tested their activity. the results of this experiment are shown below. these findings suggest that α-amanitin-treated cells will have reduced levels

Answers

The answer is reduced levels of mRNA synthesis. This is due to the fact that alpha-amanitin interferes with polymerase II that is involved in transcription of mRNA precursors.
The alpha-aminitin inhibits translocation of this polymerase from DNA after a transcription round. This therefore renders the enzyme unavailable for next transcription.
It also reduces the rate of translocation of the polymerase II along the DNA hence slows transcription.

The nitrogen removed from an amino acid generates ammonia, which is converted to ________ and excreted in the urine

Answers

The correct answer is urea. 

Urea is formed from the deamination (removal of amine group) of amino acids producing a highly toxic ammonia. Ammonia will then join carbamyl phosphate to form citrulline. Citrulline will then cycle through the urea cycle until it forms arginine. Arginine then will be broken down to ornithine and urea. Urea is excreted in the urine and ornithine is used to replenish citrulline.
Final answer:

Ammonia, produced from the deamination of amino acids, is highly toxic and is converted into urea in the liver. Urea is then excreted in the urine by mammals, including humans, as part of the urea cycle to maintain nitrogen balance and prevent toxicity.

Explanation:

The nitrogen removed from an amino acid generates ammonia, which is then converted to urea and excreted in the urine. When proteins are broken down into amino acids, they undergo deamination, where the nitrogen-containing amino groups are removed and form ammonia (NH3), which is converted into the less toxic compound, urea, primarily in the liver. This process is vital for detoxifying ammonia, and the urea produced is then excreted by the kidneys. Mammals, including humans, excrete primarily urea, with small amounts of ammonium ion (NH4+), through urine. This urea formation and excretion is part of the urea cycle, an efficient system to remove nitrogenous wastes from the body, which is essential for maintaining the body's nitrogen balance and preventing the accumulation of toxic levels of ammonia.

According to the textbook, what role does the stomach play in feelings of hunger?
a. pressure receptors in the stomach walls signal fullness or emptiness.
b. fullness receptors and stomach contractions both play a role.
c. stomach contractions signal the brain that it is time to eat again.
d. pleasure receptors within the lower intestine, not the stomach walls, signal fullness or emptiness.

Answers

A. Pressure receptors in the stomach walls signal fullness or emptiness
Final answer:

The stomach contributes to feelings of hunger through both fullness receptors and stomach contractions. When these receptors are not activated, due to an empty stomach, the feeling of hunger is experienced. However, pleasurable receptors in the lower intestine do not contribute to the signal of hunger, rather they signal satisfaction after eating.

Explanation:

According to textbooks, the stomach plays a key role in the feelings of hunger via both fullness receptors and stomach contractions. When the stomach is empty, fullness receptors are not activated, which allows for the sensation of hunger. This is statement 'b' in your provided options. Additionally, physical stomach contractions also signal the brain that it's time to eat again, which can intensify feelings of hunger. The lower intestine does contain pleasurable receptors, but their role is mainly to signal satisfaction after eating, not hunger itself.

Answers

1-plates     ........................................................                                            2-surface

Answer:

Crustal plates; crustal plates

Explanation:

Geology considers that the mountains are recent formations, so they did not suffer as much wear and tear through exogenous relief modification agents as the action of winds and rains. The mountains are commonly formed by the action of crustal plates (or tectonic plates), which collide and generate folds or uplifts on the surface.

Most volcanic eruptions and earthquakes are the result of tectonic plate movement. When they recede or collide, magma tends to rise in the case of volcanoes, or the earth tends to tremble in the case of earthquakes. Depending on the force of the pressure exerted, the volcano is "uncapped" and erupts.

Answers

An advantage of innate immunity is ITS BARRIERS THAT PREVENT PATHOGENS FROM ENTERING INTO THE BODY.
The innate immune system is a sub-component of the humans' immune system; it is made up of cells and mechanisms that prevent the body from been invaded by infectious agents. The innate immune system is the first line of defense of the body when a pathogen try to infect the body, the system is normally activated by the presence of pathogens or their secretions. The innate immune system is made up of two basic components:
1. physical barriers such as skin, respiratory tract, gastrointestinal tract, cilia, eyelashes, etc.
2. Defense mechanisms such as secretions, bile, mucous, gastric acid, tears, sweat, saliva, etc.
Final answer:

Innate immunity is advantageous for its broad-spectrum defenses, such as physical and internal barriers, against pathogens. Adaptive immunity, which is more sophisticated, targets specific pathogens and uses antibodies to kill invading cells which can prevent autoimmune disease.

Explanation:

An advantage of innate immunity is its barriers that prevent pathogens from entering into the body. Innate immunity, accompanied by adaptive immunity, works as the first line of defense against harmful microbes and substances. This system includes physical barriers like skin and mucous membranes, and internal defenses like inflammation and fever. It is not specific to any particular pathogen and does not have immune memory but forms a crucial part of the body's defense mechanism.

On the other hand, adaptive immunity has the specificity of its individual cells which specialize in the removal of one type of antigen and the use of antibodies to cause cell lysis, killing invading cells. The numerous steps in the activation of its cells can prevent autoimmune disease, effectively providing another form of immunity that complements innate immunity.
