Answer:

1)All minerals are naturally occuring.

2)They have to have a crystalline structure and a definite chemical composition.

3)They are inorganic.

4)They are a solid.

Explanation:

1-You have to find a mineral in the nature. It cannot be created in a lab.

2-Crystallline structure is the ordered arrangement of ions, molecules, or atoms in an object.

3-Inorganic means that the object has not bonded with carbon.

4-Solid means that it is not fluid and is hard and stable.

Hope this helps! :)

For each population description, identify which Hardy-Weinberg assumption is violated?
zavuch27 [327]

Answer:

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.

Explanation:

1. A small and isolated population of seals living in a stable environment with no genetic mutations.❌

1. false

Hardy-Weinberg assumption is not violated for a small population as seen in this case.

2. A large population of fish where females mate with males based on size.❌

false

Hardy-Weinberg assumption is not violated for an instance where mating is not random as seen in this scenario.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.❌

False

Hardy-Weinberg assumption is not violated for where gene flow is seen among population in this scenario.

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.✔

True

Hardy-Weinberg assumption is violated for in this situation due to large population size.

5. A small population of spiders living in an environment that strongly favors larger individuals.❌

false

Hardy-Weinberg assumption is violated for a small population and natural selection occurring as its obvious in this case.

There are five primary Hardy-Weinberg assumptions:

A. no mutation,

B. random mating,

C. No gene flow,

D. infinite population size,

E. No selection.

If the assumptions are exempted in a gene, the population of that gene might undergo evolution causing a resultant change in the gene's allele frequencies.

Ivan

Answer:

the air in our lungs is measured in terms of lung volumes and lung capacities. volume measures the amount of air for one function, like such as inhalation or exhalation. capacity is any two or more volumes, for example, how much can be inhaled from the end of a maximal exhalation

if i'm wrong i'm really really sorry!!
