Explanation:
What type of evolutionary adaptations did plants acquire to allow them to grow in areas that were not directly on a water source? A. Angiosperms evolved flowers, which could catch rainwater, reducing the dependence on ground water sources. B. Vascular seedless plants evolved specific structures to transport and hold fluids, reducing dependence on water sources. C. Gymnosperms evolved seeds, which they could alter to need less water. D. Non vascular plants evolved chloroplasts to allow them to get energy from the sun, instead of relying on water for energy.
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.
What is vascular plants?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.

Modern plant-breeding techniques (artificial selection in action) have reduced genetic variability in many of our most commercially valuable plants. To most people, that would generate a shrug. However, a biology student that has studied evolution understands the problem with this. Briefly explain why there is an issue with this.
Answer:
There is an issue with the artificial selection.
Explanation:
There is an issue with this artificial selection because the genetic variability is reduced when we do again and again the artificial selection. In the artificial selection, the selected genes are combined with the one another and does not allow natural fusion or combination of genes that is responsible for the genetic variability in the organisms so that's why we can say that this artificial selection is an issue that reduce genetic variability.
The prevalence of CRE infections in health care settings has increased significantly in recent years, in part because these organisms are able to share plasmid-encoded resistance genes. Which method of horizontal gene transfer is most likely responsible for transfer of the plasmid between bacteria
Answer:
Bacterial conjugation
Explanation:
Carbapenem-resistant Enterobacterales (CRE) are different types of bacteria that lead to infections in healthcare settings. Moreover, a plasmid is a small piece of DNA that can replicate independently from the bacterial chromosome. Bacterial conjugation is a type of horizontal gene transfer by which plasmids are transferred from one bacterium referred to as 'donor' into another called 'recipient' by sex pili. Plasmid transfer is unidirectional and depends on physical contact between bacterial cells. In this case, it is expected that this type of DNA transport mechanism occurs among patients occupying the same rooms in healthcare settings.

The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.
The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.
Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, employees are exposed to them and are vulnerable to harm from these chemicals.
There are many types of hazardous chemicals to be wary of, such as:
Carcinogens NeurotoxinsAcids Systemic toxins Asmogens Silica dust LeadIn the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.
The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.
Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.

will mark Brainliest!!!!!! To corroborate information is to?
find evidence that opposes a scientific position.
find evidence that supports a scientific position.
find evidence that proves a scientific position.
find evidence that disproves a scientific position.
The most correct option as to what corroborating information means would be to find evidence that supports a scientific position.
Corroborate is an English word that means 'to agree with' or 'give credence to'.
Hence:
Finding evidence that opposes a scientific position is a wrong option because that is the complete opposite of what corroborate means. Finding evidence that approves a scientific position is also a wrong option because corroborating a statement does not necessarily make the statement to be scientifically correct.Finding evidence that disproves a scientific position is also incorrect. Corroborate neither translates to approve nor disprove,Therefore, the correct option that clearly explains what corroborate means in the context of science is to find evidence that supports a scientific position.

The ovals above represent mangrove islands of various sizes and distances from shore. According to the MacArthur/Wilson Island Biogeography Model, which island is expected to have the LOWEST number of insect species at equilibrium
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.

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?
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.

In meiosis, sister kinetochores are attached to the same pole of the cell during meiosis I, and sister chromatid cohesion is released during anaphase II. What would be the likely result if sister kinetochores were attached to different poles of the cell during meiosis I and sister chromatid cohesion was released during anaphase I
Answer:
sister chromatids would migrate to opposite poles in anaphase I
Explanation:
Kinetochores are multiprotein structures that establish the attachment of spindle microtubules to the chromatids during cell division (either mitosis or meiosis). Sister chromatid cohesion at the centromeres refers to the mechanism by which sister chromatids are paired and held together during meiosis I. This process (sister chromatid cohesion) is fundamental to ensure the correct orientation of chromatids on the spindle microtubules and their subsequent segregation in meiosis II. The fusion of sister kinetochores in meiosis I underlies sister chromatid cohesion during this stage of the cell division, thereby their disruption or destruction of sister chromatid cohesion would lead to separation and segregation of sister chromatids to opposite poles of the cell in anaphase I.
