An environmental change than an animal must respond to could be a change in climate which affects humidity and temperature.  If it could not adapt, it will die out and only the ones that could adapt will live on.  This is called natural selection

Answer:

Temperature is the most important environmental change that an animal must respond to in order to keep a stable internal environment. A right internal temperature of the body is crucial for working of enzymes present in the body and if these enzymes do not get the right temperature they will not work properly and the animal will dye.

There are two types of animals cold-blooded and warm-blooded. Cold-blooded animals require sun energy to raise their body temperature but warm-blooded animals like mammals auto regulate their body temperature which requires lots of energy.

If an organism could not adapt to an external environment like temperature then it will dye soon or later because natural selection eliminates those organisms which are unable to adapt the changing environment.

What does it mean when a trait is independent from another trait? Give one example.
coldgirl [10]

Answer:

It means one trait does not influence the expression of the other. Example is given in the explanation section.

Explanation:

A trait is the phenotypic characteristics an organism possesses. It is determined and controlled by genes. According to Mendel, an organism receives two forms of every gene called ALLELE. Each allele of a gene encodes a different trait.

Mendel, in his law of independent assortment stated that the inheritance of a trait encoded by the alleles of one gene does not influence the inheritance of another trait encoded by the alleles of another gene. A trait is said to be independent of another if it doesn't influence the expression of the other trait.

An example is the seed colour and seed shape trait in a plant. The seed colour trait is encoded by a certain gene and its expression and inheritance is independent of the seed shape trait encoded by another gene.

Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours
romanna [79]

<u>Answer:</u> The final population of Proteus vulgaris after 6 hours is 3.71\times 10^{6}cells

<u>Explanation:</u>

We are given:

Proteus vulgaris divides and doubles every 28 minutes

Total time given = 6 hours = 360 min      (Conversion factor: 1 hr = 60 min)

Number of times Proteus vulgaris doubles in 6 hours = \frac{360min}{28min}=12.857times

Calculating the number of bacteria after 6 hours under ideal conditions:

We are given:

Initial population = 500 cells

Number of times it doubles = 12.857 times

Final Proteus vulgaris population = 500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells

Hence, the final population of Proteus vulgaris after 6 hours is 3.71\times 10^{6}cells
