Explain the idea of "survival of the fittest" with regards to a population of beavers in a lake in which some have large incisor teeth and others have small incisor teeth.

Answers

If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will them be able to reproduce therefore passing down the gene with larger incisor teeth

The study of gradual change is called evolution.

The correct answer is mentioned below.

What is evolution?Evolution is a change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.

According to the question,

If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will then be able to reproduce therefore passing down the gene with larger incisor teeth.

what is the cause and effect of stop codone mutation?

Answers

Answer:

Nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Alejandro wants to find the speed of his car in meters per second. His car traveled 50 cm. It took 5 seconds to travel 50 cm. How fast did his car go?

Answers

Answer:

0.1m/s

Explanation:

Speed can be calculated using the formula;

Speed (m/s) = distance (m) ÷ time (s)

According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.

However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.

100cm = 1m

50cm = 50/100

= 0.5metres.

Speed = 0.5/5

Speed = 0.1m/s.

The car travels as fast as 0.1m/s.

A body cell has been growing and synthesizing proteins. In the nucleus of this body cell, DNA replication is taking place, and a copy of the cell's genetic material is copied. Which of the following is the best conclusion you can make about the life cycle of this cell?

Answers

The best conclusion you can make about the life cycle of this cell is that the cell is in the S phase of interphase and will move next to the G2 phase.

S phase (Synthesis Phase) is the phase of the cell cycle in which all of the chromosomes (DNA) are replicated within the nucleus. During this phase, the DNA is effectively doubled as each chromosome contains two sister chromatids. After the S phase, the cell enters the G2 phase where various proteins (such as microtubules) are synthesized.

what is meant my urbanization and industrialization? How they degrade the environment ​

Answers

Urbanization is defined as “the process of making an area more urban” or an increase in the amount of people living in towns or cities. Industrialization is defined as “the development of industries in a country or region on a wide scale” meaning a strong military with modern weapons, factories to create things, modern cars and boats etc. Urbanization and industrialization put a strain on the environment because of carbon gases emitted, effectively warming the earth up, destruction of trees which lowers our overall oxygen available, destruction of animal homes which will kill animals or cause unwanted interactions between humans and animals, and the pollution of natural resources such as local ponds, streams or the ocean.
