A) biome

Explanation - Biome is the ecological area where flora and fauna adapts themselves according to the environment or niche they are living in. An ecosystem is a group of living beings alongside the nonliving things of their condition, communicating as a framework.

Community is a group of organisms that interact with each other and carry out their work accordingly. Organism describes a particular being of a species. Therefore, Biome best suits the options given in the question.

A man borrowed money at a bank $1400 at the rate o 3% for 3 years. a) Find the simple interest b) Find th total money repaid aft
zhannawk [14.2K]

Answer:

a) The simple interest is $126.

b) The total money repaid after 3 years is $1526.

Step-by-step explanation:

A man borrowed money at a bank $1400 at the rate o 3% for 3 years.

a) Find the simple interest

\longrightarrow{\sf{\red{S.I =  \dfrac{PRT}{100}}}}

  • → S.I = Simple Interest
  • → P = Principal
  • → R = Rate
  • → T = Time

Substituting all the given values in the formula to find the Simple Interest :

\longrightarrow{\sf{S.I =  \dfrac{PRT}{100}}}

\longrightarrow{\sf{S.I =  \dfrac{P \times R \times T}{100}}}

\longrightarrow{\sf{S.I =  \dfrac{1400 \times 3 \times 3}{100}}}

\longrightarrow{\sf{S.I =  \dfrac{14 \cancel{00}\times 3 \times 3}{1 \cancel{00}}}}

\longrightarrow{\sf{S.I = 14 \times 3 \times 3}}

\longrightarrow{\sf{S.I = 42 \times 3}}

\longrightarrow{\sf{S.I = 126}}

\star{\underline{\boxed{\pmb{\sf{S.I = \$126}}}}}

Hence, the simple interest is $126.

━━━━━━━━━━━━━━━━

b) Find the total money repaid after 3 years

\dashrightarrow{\sf{\pink{A = P + S.I }}}

  • → A = Amount
  • → P = Principal
  • → S.I = Simple Interest

Substituting all the given values in the formula to find the Amount :

\dashrightarrow{\sf{A = P + S.I }}

\dashrightarrow{\sf{A = 1400 + 126 }}

\dashrightarrow{\sf{A = 1526}}

\star{\underline{\boxed{\pmb{\sf{A = \$1526}}}}}

Hence, the total money repaid after 3 years is $1526.

A mouse geneticist selected for increased 12-day litter weight (total weight of a litter of offspring 12 days after birth) in a
wlad13 [49]

Answer:

12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection

Explanation:

Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.

Describe one path that a carbon atom could follow through the carbon cycle
Alik [6]

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
