The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
Answers
Answer:
Last choice: ribose; deoxyribose
Explanation:
Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.
Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base: adenine, thymine, cytosine, guanine, and deoxyribose.
Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.

Diane Dodd raised different fruit fly populations on different food sources. She found that after about 40 generations the evolution of reproductive isolation was under way. The mechanism of evolution responsible for this was Group of answer choices
Answers
Answer:
Natural selection.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
In this scenario, the mechanism of evolution responsible for this was natural selection because after about 40 generations the evolution of reproductive isolation was under way for the fruit fly. Thus, the more the offsprings that are reproduced by the parent organism, the more likely are they to survive.
Additionally, there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.
do you think that the life of elderly people suffering from diabetes mellitus should be extended by giving them artificially produced insulin
Answers
Explanation:
The prevalence of type 2 diabetes is increasing among older adults as is their diabetes-related mortality rate. Studies suggest that tighter glucose control reduces complications in elderly patients. However, too low a glycosylated hemoglobin (HbA1c) value is associated with increased hypoglycemia. Moreover, the appropriateness of most clinical trial data and standards of care related to diabetes management in elderly patients is questionable given their heterogeneity. Having guidelines to safely achieve glycemic control in elderly patients is crucial. One of the biggest challenges in achieving tighter control is predicting when peak insulin action will occur. The clinician’s options have increased with new insulin analogs that physiologically match the insulin peaks of the normal glycemic state, enabling patients to achieve the tighter diabetes control in a potentially safer way. We discuss the function of insulin in managing diabetes and how the new insulin analogs modify that state. We offer some practical considerations for individualizing treatment for elderly patients with diabetes, including how to incorporate these agents into current regimens using several methods to help match carbohydrate intake with insulin requirements. Summarizing guidelines that focus on elderly patients hopefully will help reduce crises and complications in this growing segment of the population.

Explanation:
Un individuo es haploide (n) cuando sólo posee un juego de cromosomas en el núcleo celular, mientras que un individuo es diploide (2n) cuando posee dos juegos de cromosomas. En general, los organismos pluricelulares diploides poseen dos tipos tipos de células: 1-germinales (gametos) haploides y 2-células somáticas diploides. El hámster Sirio posee 22 pares de cromosomas, es decir 44 cromosomas (2n=44) en sus células somáticas diploides y 22 cromosomas en sus células germinales haploides, es decir, en sus óvulos (gametos femeninos) o espermatozoides (gametos masculinos) cuya fusión durante el proceso de fertilización da lugar a un cigoto diploide. Por otra parte, el hámster Chino, el cual se considera un organismo modelo en citogenética, posee 22 cromosomas en sus células diploides (2n=22) y 11 cromosomas (n=11) en sus células haploides.

In humans, ventilation, digestion, and blood flow are important biological processes. Explain the relationship between the structure of tissues or organs and one of these processes.
Answers
Answer:
I am assuming the question is asking how do the processes relate to one another.
Explanation:
Ventilation happens in the lungs, where carbon dioxide and oxygen are exchanged in the alveoli. This is done via cappilaries that surround the alveoli. Cappilaries are small blood vessels, which are collecitelvy part of the blood flow system (circulation) of the body. In reguards to the digestion, there are capillaries in the vili (which are tiny finger-like structures) so that they can pick up the nutrients during digestion. Another way blood flow and digestion are connected is because the stomach is a muscle, thus is moves and requires energy. That energy comes from the oxygen and nutrients that is supplied by the blood. These are just some examples.
What are australopiths, how many groups are there, and what do they date to? Which one is derived and therefore not part of our direct evolutionary line?
Answers
Answer and Explanation:
Australopithecines were a group of ancestral animals that were very similar to chimpanzees, but had common characteristics with humans, which is something normal, when we think that these animals are one of the ancestors of human beings. These animals walked on two legs, like humans, but they had very small brains and teeth that were bigger and heavier than those of humans. There were eight groups of australopithecines and they date from 8 million to 1.5 million years ago.
Among these groups, it is believed that Australopithecus afarensis is a group that has no direct ancestry with humans, being a group that did not thrive during the evolutionary process.

the discovery of isotopes disprove one part of
Dalton's atomic theory
Answers
Answer: Because Daltons theory states all atoms of a given element are identical in mass and properties.
Explanation:
The discovery of isotopes demonstrated that atoms of the same element can have different atomic weights, implying that atoms of the same element are not identical in every way.
What is Dalton's atomic theory?Dalton's atomic theory postulated that matter is made up of indivisible particles known as atoms, and that atoms of the same element are all identical and cannot be created or destroyed.
Compounds are formed by the simple combination of atoms into compound atoms.
Dalton, John Experiments with gases became possible at the turn of the nineteenth century, prompting John Dalton to propose a modern theory of the atom based on certain assumptions.
Dalton's theory is debunked. This is because Dalton's theory states that all matter is made up of identical, indivisible, and indestructible atoms. Isotopes have the same element but a different number of neutrons.
Thus, this way, the discovery of isotopes disprove one part of Dalton's atomic theory.

Answers
The change in the tilt of the Earth can affect the distribution of sunlight and thus influence temperatures on Earth.
Earth's tilt and temperatureThe tilt of the Earth, known as obliquity, affects the distribution of sunlight and influences temperatures.
A greater tilt leads to more pronounced seasons, with hotter summers and colder winters, while a lesser tilt reduces the seasonal contrast. These changes occur over long timescales.
