Students who take a PE class and who will be eating sugary snacks before PE.

Explanation:

The control variable (or control group) is an experimental element which is constant or unchanged throughout the course of the experiment.

The option "students who take PE class and who will be eating sugary snacks before PE" will remain unchanged and constant because the whole point of the experiment is to see the effects on students performance in PE after eating sugary snacks.

Hope this helps :)

Explanation:

el3m3nt is pure substance and is only made up of one type of atom it cabt be broken down into simpler substance

molecules form when two or more atoms form chemical bonds with eachother

The biggest difference between elements and molecules is that elements only have one TYPE of atom, while molecules have MULTIPLE types of atoms. The statement is true.

When two or more atoms are connected by a chemical bond will form a molecule.

The fundamental unit of element is  atom, which consist of a nucleus and its surrounding electrons.

There are different types of molecules like diatomic molecules where only two atoms are combined. For example carbon monoxide (CO) made of a single atom of carbon and one of oxygen.

This diatomic molecule can be homonuclear diatomic molecule, like oxygen (O2) and nitrogen (N2).

Similarly another type called polyatomic molecules have more than two atoms, for example water (H2O) and carbon dioxide (CO2).

The molecular weight of a molecule is calculated by sum of total atoms' atomic weights present in it and  represented by Avogadro's number (6.02214076 × 1023).

Answer:

not 100% sure but

Explanation:

might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.

Answer:

Food habits, predators.

Explanation:

The biggest reasons are food habits and predators, most birds who nest on the ground either can't fly or use this to be closer to their food. A ground bird (Like quail) can fly but choose to be more ground-based birds.

Most of the time it's because these birds forage for food like ground insects, seeds from the brush that grows on the ground, or fallen fruit.

Most birds that live in the trees feast on seeds, leaves, or insects found close to where they choose to nest. They may also want to escape any predators that may be towards the ground.

A person cannot exhibit the disorder because they don't experience the condition because they have a healthy copy of the gene on their other sex chromosome.

A disorder is a functional abnormality or disturbance that affects an individual's physical, mental, or emotional health.

They have the potential to pass on the mutated gene to their offspring, but they do not exhibit the disorder themselves because they have a normal copy of the gene on their other sex chromosome.

In the case of X-linked disorders, females have two X chromosomes, while males have one X chromosome and one Y chromosome. Females can be carriers for X-linked disorders if they inherit one mutated X chromosome from one parent, and one normal X chromosome from the other parent.

Males, on the other hand, cannot be carriers of X-linked disorders because they only have one X chromosome.

Therefore, a person can be a carrier for a sex-linked disorder if they have one copy of a mutated gene on one of their sex chromosomes, but not on both.

Answer: They tend to support large planktonic

communities because (of higher dissolved oxygen and nutrient concentrations).

Explanation:

Planktonic communities are made up of basic organisms that forms the oceanic food web. They are broadly divided into Phytoplankton (these are the producers), Zooplankton (these are the consumers) and Bacterioplankton (these are the recyclers).

High-latitude ocean water is mostly affected by the quantity of oxygen and nutrients it contains. Large planktonic communities thrives in these aquatic environment because is contains higher amount of dissolved oxygen and nutrient concentrations which forms part of their basic needs for survival. This is so because changes in ocean water can impact all levels of the food web. Increase or decrease in ocean temperature can modify the plankton diversity and distribution directly by altering it's metabolic rates and growth.

Therefore due to the geographic location of high latitude ocean, higher dissolved oxygen and nutrient concentrations favour the survival of a larger planktonic communities than other ocean parts.

Science is based on observations and facts.

Pseudoscience and Myths are based on opinions, beliefs, or biases.

Let me know if this helps!

Pseudoscience

Science

Myths

Humans use science as a systematic approach to understanding the natural world. Its goal is to eliminate prejudice by using facts and observations to identify and describe underlying concepts and mechanisms. Pseudoscience lacks scientific rigor and relies on unproven claims driven by prejudices or beliefs, resulting in misunderstandings.

The basis of real science is actual data collected by experiment, observation, and application of the scientific process. Myths are important cultural myths that may not reflect scientific reality. While myths have their roots in tradition, they should not be confused with facts verified by science. Unlike pseudoscience and myths, which lack evidence-based scrutiny, science provides a solid framework for unbiased observation and testing.

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.
