How does a population reach carrying capacity?Give examples.

Biology
1 answer:
Mashcka [7]3 years ago
4 0

Answer: By either emigration or natural increase.

Explanation: Natural increase is where in a population, the birth rate, or number of live births per year, is greater than the death rate, or deaths per year. Emigration is when individuals leave their region to move to another, often due to economic or political reasons. Eventually, a population will reach its carrying capacity, where the land the population occupies is only just able to support the population. Once the carrying capacity is breached, the population will start to collapse.

Dvinal [7]

Answer:

The correct answer will be- true and structural specializations

Explanation:

The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.

This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.

This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.

Thus, true and structural specializations are the correct answer.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has  dominant allele  and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below:frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}
