What is the purpose of using a pedigree?a to study the causes of traits that are acquired during an organism’s life
b to understand patterns of inheritance in organisms
c to determine mating patterns in organisms
d to identify traits that are acquired during an organism’s life

Answers

The pedigree's purpose is to understand patterns of inheritance in organism. Examination of the pedigree utilizing the standards of Mendelian legacy can decide if a characteristic has an overwhelming or passive example of legacy. Families are frequently built after a relative harrowed with a hereditary issue has been distinguished.

The purpose of pedigree is to trace the ancestory. Therefore, the correct answer is B, i.e., to understand the patterns of inheritance in organisms. it helps in knowing that what characters are passed to the offsprings, what disease may be transferred to the offsprings, and also the mode of inheritance of the disease.

Prairie soils (mollisols) are _______.a.
poor in organic matter
b.
easy to cultivate and fertile
c.

Answers

Correct answer: B). Easy to cultivate and fertile

The prairie is grassland soils that possess a dark colored surface and these soil are highly fertile in nature. These soils are rich in minerals like calcium and magnesium.

The dark color of soil comes from the added organic matter to the soil that comes from the roots of prairie plants. They are formed in the areas that are too dry to be forested, but too wet to be desert.

Hence, the correct answer would be option B.

What are the parts or process that can describe an ecosystem?a. chemical changes and flow of energy
b. chemical changes and flow of water
c. physical changes and flow of energy
d. physical changes and flow of water

Answers

Answer:

a. chemical changes and flow of energy

Explanation:

Energy flow from one organisms of one tropic level to other, matter cycling and transformation of energy are the functions that sustain the ecosystem. Transformation of solar energy into chemical energy by plants serves as energy source for all heterotrophic living beings in the system. The heterotrophic organisms digest the ingested food (chemical change) to release energy to support their life processes. The energy stored at one tropic level is carried to next tropic level via food chain and food webs and represents the interaction between living components of ecosystem.

it is A both chemical changes and flow of energy
