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.

Answer:

A. False, not all organisms can make their own food, only plants and some bacteria.

Explanation:

It's right

The description of the statement whether it is true or false is described below:

Plants prepare their own food with the process of photosynthesis which utilizes carbon dioxide and water and synthesizes glucose in the presence of sunlight.

Plants, some photosynthetic algae, and some bacteria prepare their own food with the help of sunlight. They have a photosystem that captures the energy of sunlight in the food production mechanism.

Therefore, it is well described above.

Answer:

TFH cells in the germinal center

Explanation:

The Tfh cells, present in the germinal center, are responsible for maturing and stimulating the class change of immunoglobulins (such as the change from IgM to IgE). This change could stimulate the new classes of immunoglobulins to act with stimulating antibodies to produce an immune response.

It is important to point out that the germinal center is the activated point of a lymphoid follicle that contains B and T lymphocytes, which act in the memory of the cells of the immune system.

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.

There are few island on earth which are insect free due to atmosphere and sea breeze which do not complements the insects breed.

These islands attract tourists more because of no or very few insects, tourist have no fear of getting sick during their stay on these islands.

Antarctica is mosquito free continent. The island in Antarctic ocean are mosquito and have very few insects due to lack of stagnant water available for their breeding.

Iceland, Seychelles and few other island are insect free or have very low amount of insects there. The coral island is all surrounded by water and there is no connection of this island with the land.

There is very less stagnant water and ponds which can cause the insects to survive.

Answer:

so, what is the question?

Explanation:

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.

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:

Answer:

B

Explanation:

In the given scenario, vascular seedless plants evolved specific structures to transport and hold fluids, reducing dependence on water sources. The correct option is B.

A plant that basically have a specialized conducting system which entails xylem and phloem, the tracheophyte is referred to as vascular plants.

Vascular plants are widely recognized as tracheophytes. Vascular tissues are xylem and phloem for conduction of water and food respectively.

They allow plants to grow in height in the air without even drying out. Vascular plants also have roots, stems, and leaves.

Seedless vascular plants are the ones which have vascular tissue but though do not produce seeds as well as flowers.

In such vascular plants, for instance, ferns and horsetails, the plants multiplies using haploid and unicellular spores on the place of seeds.

Thus, the correct option is B.

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. 

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.

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.

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.
