Explanation:
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
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
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.

the discovery of isotopes disprove one part of
Dalton's atomic theory
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.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community
Answer:
The elephants are the keystone species in this ecosystem.
Explanation:
The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.
This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.

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.
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.
Where is amyglada located in a brain ? How does it function ?
Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.
Explanation
The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction
The mass of the products is larger than the concentration of the reactants in an energy absorption process.
The power of the reaction mixture is larger than the radiation of the outputs in an energy-releasing process.
As substances disrupt bonds, energy released, and then when outputs make new bonds, release energy.
Exothermic processes release energy, whereas endothermic reactions consume it. There is no general change in the quantity of energy throughout a chemical process, whether it collects or releases it.

Why could the change in the tilt of Earth cause temperatures on
Earth to change?
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.
However, short-term climate variations are primarily influenced by factors like greenhouse gases, ocean currents, and atmospheric circulation patterns.

The sugar in RNA is, the sugar in DNA is
deoxyribose; ribose
glucose; deoxyribose
ribose; glucose
ribose; deoxyribose
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.
