a volume of helium occupies 11.0 L at a pressure of 98.0 kpa. what is the new volume if the pressure drops to 86.2 kpa​

Answers

Answer 1
Answer:

12.506 L

Explanation:

We’ll use Boyle's Law of ideal gases;

P₁V₁ = P₂V₂      whereby;

P – pressure

V – volume

We replace variable with given values;

98 * 11 = 86.2 * V₂

V₂ = 98 * 11 / 86.2

V₂ = 12.506 L

Which of the following is not a source of genetic variation?

Answers

 Mitosis


Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. 

What are 3 ways that humans are considered a diverse population?

Answers

no two humans are the same

Final answer:

Humans demonstrate significant diversity in biological traits, social characteristics, and agricultural practices. This diversity is reflected in physical attributes and social differences between societies, alongside the wide range of plants and animals cultivated for various environmental conditions.

Explanation:

Humans are considered a diverse population in many ways, but there are three main aspects that stand out.

Biological Diversity: With billions of humans on the planet's surface, human beings possess considerable biological diversity. Visible traits like skin color, or invisible genetic markers like blood type, contribute to this diversity. Within any subcategory, there will be more variation than that exists between different categories.

Social Diversity: Human social diversity arises from our societies' differing physical or social characteristics. These can vary greatly, resulting in a rich tapestry of cultures, languages, traditions, and social norms across the globe.

Agricultural Diversity: Humans have cultivated an immense diversity in domestic plants, animals, and fungi based on local needs and environmental factors. For example, potatoes have been bred into thousands of varieties to cope with specific soil and climate conditions—this mirrors cultural diversity within human populations.

Identify a specific structure in a single celled organism. State how that structure is involved in the survival of the organism

Answers

Pseudopodia in amoeba is a specific structure in a single-celled organism.

What do amoebas do to humans?

Multiple of those contaminated show no signs at all—the amoeba lives calmly in their gut, providing on bacteria without causing trouble.

But in others, the parasite attacks the gut itself and can cause potentially fatal diarrhoea, intestinal ulcers, and liver spots.

Thus, Pseudopodia in amoeba is the answer.
