You are maintaining a small population of fruit flies in the laboratory by transferring a small number of the flies to a new cul

ture bottle after each generation. After several generations, you notice that the viability of the flies has decreased greatly. What is the best way to reverse this trend?

Answer:

Cross the flies with the flies from another population

Explanation:

Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.

Describe what happens as a plant's turgor pressure increases and decrease AS MUCH POINTS AS I CAN GIVE​
Dimas [21]

Answer:

Brainliest pls

Explanation:

Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk).

Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.

nirvana33 [79]

Answer:

Physical Change:

- Boiling water

- Breaking a pencil

- Water evaporating

- Denting a car door in an accident

- Tearing paper

- Ice melting

- dissolving

Chemical Change:

- Something rusting

- photosynthesis

- metabolism/digestion

- Nuclear power [atoms are arranged differently]

- Smashing paper with two metal balls, burns paper

- Electricity in water, breaks H2O into H2 and O2

-----

physical change is when there is only physical change occurring--and it can typically be undone easily,

whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.

hope this helps!!

The student nurse is reviewing the records of a pediatric client. Which statement about the client's progress indicates the need
lilavasa [31]

Answer:

<em>"Maturation refers to the child's increases in body size."</em>

Explanation:

The statement "Maturation refers to the child's increases in body size" does not tell anything about the state of the patient and it needs to give a clear explanation.

Growth can be described as the physical increase in size of a person.

Development can be described as the process by which children learn different skills as they grow up.

Maturity can be described as the growth in different body system which leads to the development of different skills in the children.

If one year was one foot, how long would the Cretaceous be (65 million) in miles?
Harman [31]

If one year was a foot then 65 million years will be 65 million feet. 1 mile=5280 feet so.

65 million divided by 5280= 12310.6

So your answer would be 12,310 miles.
