Which of the following statements does NOT contribute to the evidence in support of evolution?(A) Sequences of fossils have been found that show a gradual series of changes in form among organisms.
(B) Species thought to be related through evolution from a common ancestor show many anatomical similarities.
(C) The stages of embryological development in animals are quite similar among highly diverse types of organisms.
(D) Similarities in chromosome structure, DNA sequence, and amino acid sequence suggest relationships among organisms descending through evolution from a common ancestor.
(E) The most well adapted individuals do not always produce the most fit offspring.

Answers

Answer 1
Answer: Definitely option E! This refers to exceptions to the 'survival of the fittest' - but the theory still holds despite these anomalies.

Which of these nutrients can be found in all organic compounds? nitrogen calcium carbon phosphorous

Answers

All organic compounds contain the nutrient known as carbon. As a fundamental building block of life, carbon will always enjoy a presence in organic compounds, from simple structures and rudimentary forms of life through complex lifeforms such as human beings.

The nutrient that can be found in all organic compounds is the carbon. The reason why carbon is found in all organic compounds is described below.

What is organic compounds?

Organic compounds are those chemical compounds found in living organisms which are made up of carbon-hydrogen bonds.

Carbon is the main element in organic compound since it forms its bonds. Typical examples of these organic compounds are:

  • Carbohydrates

  • Protein

  • Fat and oil

Therefore, The nutrient that can be found in all organic compounds is the carbon.

Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results
provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.

Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice

Answers

Answer:

Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

The correct answear is B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.

Explanation:

Naltrexone is a non-selective opioid antagonist, it competes with these at the level of the receptors and thus reduces their effects.

The responses A, C, D and E does not weaken the support for the

researches ´ predictions, and are not relevant to the argument.

What underlying theme do the four molecular techniques share?

Answers

All of the following such as DNA sequencing, PCR, electrophoresis, and DNA hybridization are used in molecular techniques for genetic analysis.

What is the genetic analysis?

Genetic analysis is the science of identifying, studying, and diagnosing genetic variations in an organism's DNA. The most common molecular techniques used in genetic analysis include DNA sequencing, PCR, electrophoresis, and DNA hybridization.

All of these techniques share the underlying theme of genetic analysis, with a focus on the analysis of genetic variations in DNA. DNA sequencing is used to read and interpret the genetic code, while PCR is used to amplify specific DNA sequences, enabling their detection.

Electrophoresis is a technique that separates DNA fragments based on their size, charge, and other physical properties, and DNA hybridization is a technique that detects and quantifies specific DNA sequences by binding them to complementary DNA probes.

Nanotechnology, the atomic material is molecular and supramolecular levels of control. Also mentioned as the oldest and most common definition of nanotechnology, molecular nanotechnology today, exactly 'the control of atoms and molecules for the production of macroscale product represents a particular purpose. The more general definition of Nanotechnology National Nanotechnology Initiative by later. National Nanotechnology Initiative nanoteknoliji of 'at least one of size up to 100 nanometers in size control agent 1' is defined. Demonstrates the fact that this definition; quantum mechanical effects are important in the quantum-field scale. Thus, the definition rather than a specific technological purpose, turned into a category covering all areas of research addressing the special nature of the substances formed under the size limit of the types of technology and research. That's why "of nanotechnology" and the "nanoscale technologies" of the plural form 'is very common that the common feature of size and Applications expressed a wide range of research. Potential applications (including industrial and military) has invested billions of dollars to the state because of the diversity of nanotechnology research. US National Nanotechnology Initiative thus made $ 3.7 billion investment. The European Union and Japan has invested $ 1.2 billion, $ 750 million. Nanotechnology is defined in magnitude for earth science, organic chemistry, molecular biology, semiconductor physics, contains areas of science such as micro fabrication and naturally is very wide.

How many calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories?A. 80 calories
B. 100 calories
C. 200 calories
D. 240 calories

Answers

80 calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories. So, the correct option is (A).

What are Calories?

Calorie is defined as the amount of energy the body releases when it breaks down i.e. digests and absorbs food. The more calories a food contains the more energy it can provide to the body. When we eat more calories than we need, our body stores the extra calories as body fat.

Women need 1,600–2,400 daily calories to maintain their weight while the men need 2,000–3,000 calories. Eating fewer can lead to weight loss. By reducing the number of calories we eat per day can be an effective weight loss method.

Different nutrients provide different amount of calories, for example,

  • one gram carbohydrate provide 4 calories energy
  • one gram protein provide 4 calories energy
  • one gram fat provide 9 calories energy

Thus, 80 calories of energy will 20 grams of carbohydrates provide if 1 gram provides 4 calories. So, the correct option is (A).
