State three ways scientists base their identifications of evolutionary relationships.

Answers

Answer 1
Three ways scientists base their identifications of evolutionary relationships are:
1. Does not take genetics into account.
2. Does not consider convergent evolution.
3. Physical similarities does not mean that they are related.

Evlutionary relationships talks about relatedness between organisms, usually this can be shown by a phylogenetic tree through phylogeny. Reconnection and speciation of organisms must be considered in studying relatedness of organisms.

Explanation:

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.

*For animal anatomy* The diaphragm is ______ to the stomach. a) dorsal b) rostral c) ventral d) cranial

Answers

Cranial.
If you need any help I'll be around
Final answer:

The correct anatomical term for the position of the diaphragm in relation to the stomach is dorsal, meaning it is nearer to the back or spine side of the body.

Explanation:

In terms of animal anatomy, the correct positional term for the relationship between the diaphragm and the stomach would be dorsal. The diaphragm is dorsal to the stomach. This means that the diaphragm is toward the back, or spine side of the body when compared to the position of the stomach. Other options like rostral, ventral and cranial don't correctly describe this anatomical relationship. Rostral refers to the towards the head end, ventral indicates towards the belly side and cranial refers to towards the skull or head.

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.

What are the effects of invasion of privacy?

The first one to answer get the brilliantest button

Answers

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.

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.
