Answer:

Scientists have been concerned that human activities could cause more plants and animals to become extinct than any point in the past. Along with human-made changes in climate (see above), some of these extinctions could be caused by overhunting, overfishing, invasive species, or habitat loss

Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determin
vova2212 [387]

Answer:

See the answer below

Explanation:

Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).

Heterozygous long leg, weak muscle = Llgg

Heterozygous long leg, strong muscle = LlGg

       Llgg    x    LlGg

Offspring:

2 LLGg - Long leg, strong muscle

4 LlGg -  Long leg, strong muscle

2 LLgg - Long leg, weak muscle

4 Llgg - long leg, weak muscle

2 llGg - short leg, strong muscle

2 llgg - short leg, weak muscle

Ratio of offspring with long leg and strong muscle = 6/16 or 3/8

Ratio of offspring with long leg and weak muscle = 6/16 or 3/8

Ratio of offspring with short leg and strong muscle = 2/16 or 1/8

Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

Give an example of a thing that is living and a thing that is not living.
goblinko [34]

Answer:

Living things may be distinguished from non-living things in their ability to carry on life processes such as movement, respiration, growth, responsiveness to environmental stimuli and reproduction. This view of living may be appropriate at this age but has some limitations and can lead to the alternative conceptions above. For example movement in plants is not apparent to students and consequently they may not consider plants living.
