1. Which of the following accurately describes a typical human karyotype?A. 46 pairs of chromosomes are arranged from largest to smallest.

b. 2 sex chromosomes and 44 autosomal chromosomes are pictured.

c. 22 pairs of sex chromosomes and 1 pair of autosomal chromosomes are pictured.

Answers

Answer 1

Answer: Human cells contain 23 chromosomes and has a total of 46pairs of chromosomes. The answer is letter A. Depending on the length andmorphology, it has seven groups. They are arranged from largest to smallest. Ithas 22 pairs of homologus chromosomes known as autosomes and 1 pair of sex chromosomes,a total of 23 chromosomes. A male karyotype has a total of 46 chromosomes andgives a pair of XY while a female karyotype has a total of 46 chromosomes andgives a pair of XX. These pairing are responsible to the gender of theoffspring.

Answers

In a balanced ecosystem, the number of producers is far greater than the number of consumers.

Answer:

In a balanced ecosystem, the number of producers is far greater than the number of consumers.

Explanation:

An ecosystem is a biotic and abiotic system in which the living organisms or biotic components interact with the abiotic environment.

A food chain can be stated as the linear order of the transfer of energy and food when one organism is consumed or eaten by another organism. The energy flows in among the different trophic levels.

The producers form the lowermost trophic level. The highest energy in the energy pyramid exhibits by producers.

The primary consumers are herbivores which eat plants for their food and energy. The energy in each higher trophic level decreases when the lower trophic level organism is consumed by a higher trophic level organism.

Therefore, in a balanced ecosystem, the number of producers is far greater than the number of consumers.
