Answers

Answer 1
A challenge to traditional (pre-1860) ideas about species came from embryology, when it was discovered that embryos of dissimilar organisms, such as sharks and humans, resemble each other. Embryology involves the study of the formation and the development of an embryo and the fetus. It is one type of evidence of evolution such that the embryos of many different kinds of animals, mammals, reptiles, birds, fish among others, are similar showing a common ancestry. 
Answer 2

Answer is embryos of dissimilar organisms such as sharks and humans, resemble each other.

Further explanation

Embryology

Embryology is the study that reviews the pre-birth development of gametes (sex cells), preparation, and advancement of incipient organisms and babies. Furthermore, embryology envelops the investigation of inherent issue that happen before birth, known as teratology. The initial three weeks of the developing life, portrayed in three dimensions. Embryology has a long history. Aristotle proposed the as of now acknowledged hypothesis of epigenesis, that living beings create from seed or egg in a succession of steps. The elective hypothesis, that creatures create from previous little forms of themselves, in any case, held influence until the eighteenth century. Present day embryology created from crafted by von Baer, however precise perceptions had been made in Italy by anatomists, for example, Aldrovandi and Leonardo da Vinci in the Renaissance.

Evolution

It is the investigation of how various kinds of living beings adjust and change after some time. New species rise continuously while others go wiped out in light of fluctuating natural conditions.

How embryology provides evidence of evolution

The investigation of one sort of proof of advancement is called embryology, the investigation of developing lives. An incipient organism is an unborn (or unhatched) creature or human youthful in its soonest stages. For instance, fish developing lives and human incipient organisms both have gill cuts. In fish they form into gills, yet in people they vanish before birth.

Enzymes that breakdown disaccharides are located ________. a. in the lumen of the small intestine.

Answers

Disaccharides need to be broken down into their component subunits (monosaccharides) before their absorption. The reaction that breaks them up is hydrolysis and it is done by enzymes- glucosidases. Glucosidases are located on the brush border of the small intestine, attached to the surface of the epithelial cells. After the catalyzation of these disaccharides, the epithelial cells take up the monosaccharides and transport them inside using ATP energy. From there they are transported into the bloodstream.

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs. the bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs.
a. True
b. False

Answers

The answer would be: as the bicarbonate ion in the plasma after first entering the red blood cells

Carbon dioxide will be changed into bicarbonate ion that released into the plasma. That is why the level of carbon dioxide will influence the pH of the blood. The process will produce hydrogen ion so higher carbon dioxide will result in acidosis. It is important to keep the carbon dioxide level at a certain point to prevent blood pH stable
Final answer:

The statement is false as carbaminohemoglobin carries only about 20 percent of carbon dioxide in the blood, with the majority being transported as bicarbonate ions created by the action of carbonic anhydrase.

Explanation:

The statement that the bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the red blood cells (RBCs) is false. While some carbon dioxide is carried in this form, carbaminohemoglobin accounts for about 20 percent of carbon dioxide transport in the blood. The majority of carbon dioxide, approximately 85 percent, is transported as bicarbonate ions in the plasma. This process occurs when carbon dioxide diffuses into red blood cells and is converted by the enzyme carbonic anhydrase to carbonic acid, which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions are transported out of the red blood cells into the plasma in exchange for chloride ions, a mechanism known as the chloride shift.

In the last 10 years, sea level has risen twice as fast as in previous centuries.

Answers

I think the answer is D In the last 10 years, sea level has risen twice as fast as in previous centuries.

The claim that sea level has risen twice as fast in the last 10 years as in previous centuries is supported by significant scientific research. Option D is correct.

The Intergovernmental Panel on Climate Change (IPCC), the leading international body for the assessment of climate change, has concluded that it is extremely likely that human activities caused more than half of the observed increase in global mean surface temperature from 1951 to 2010. The IPCC has also concluded that the rate of sea level rise has accelerated in recent decades, and that this is largely due to human-caused climate change.

The other claims are not supported by significant scientific research. Claim A is contradicted by the overwhelming scientific consensus that human activities are causing global warming. Claim B is too simplistic, as weather anomalies can be caused by a variety of factors, both natural and human-caused. Claim C is not supported by the data, as global average temperatures have continued to rise in recent years. Option D is correct.

The bullock's oriole and baltimore oriole are closely related, but are they of the same species? to find out, you could see whether they ___.

Answers

The answer is successfully interbreed. 
Final answer:

To figure out if the Bullock's oriole and the Baltimore oriole are the same species, check if they can produce viable, fertile offspring. Even with different feeding habits in the same habitat, they might still be the same species if they can interbreed. But similarities like wings in birds and butterflies don't guarantee them as the same species as they could be results of convergent evolution.

Explanation:

To determine if the Bullock's oriole and the Baltimore oriole are of the same species, one could see whether they can successfully produce viable, fertile offspring. This is because according to the Biological Species Concept, two organisms are considered to be of the same species if they can interbreed and produce viable, fertile offspring. Both the Bullock's oriole and the Baltimore oriole are closely related and live in the same habitat, but have different feeding habits. However, they might still be of the same species.

For example, consider two species of birds that diverged while separated geographically but resumed their contact before reproductive isolation was complete. If these two bird species were able to interbreed, they would be considered the same species according to the Biological Species Concept.

On the other hand, birds and butterflies both have wings with similar characteristics for flight, but this does not necessarily indicate that they are the same species. Such similarities could be due to convergent evolution, where unrelated organisms independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

A false negative pregnancy test may result from a false negative pregnancy test may result from a staph infection. a sexually transmitted disease. taking the pregnancy test too early in the pregnancy. high sodium in the diet.

Answers

The correct answer is taking the test too early in the pregnancy.

A pregnancy test is a device used to test your blood or urine in order to determine whether you are pregnant or not. A pregnancy test works by detecting specific markers in your urine or blood. One of the most common marker used is human chorionic gonadotropin (hCG), a hormone produced after the implantation of the fertilized egg on the uterus. This hormone is detectable in the urine only 10 days after the fertilization of the egg, meaning that if a woman takes the pregnancy test too early it may have a false negative result.

A false negative pregnancy test may occur if taken too early, as hCG levels might be too low to detect. Thus, option C is the correct answer.

A false negative pregnancy test is a result where the test indicates that a woman is not pregnant when she actually is. The correct answer to this question is C) taking the pregnancy test too early in the pregnancy.

This occurs because the levels of the pregnancy hormone hCG (human chorionic gonadotropin) may not yet be high enough to detect.

While both false positives and false negatives are rare for home pregnancy tests, accurate timing is crucial for valid results.

A staph infection (option A) and a sexually transmitted disease (option B) do not directly affect the results of a pregnancy test.High sodium in the diet (option D) is also unrelated to the accuracy of a pregnancy test.

It’s essential to follow the instructions and use the test at the recommended time to minimize measurement errors and ensure reliable results.

The complete question is as follows:

A false negative pregnancy test may result from:

A) a staph infection.

B) a sexually transmitted disease.

C) taking the pregnancy test too early in the pregnancy.

D) high sodium in the diet.
