Answer:
Probability of Dimples and a cleft chin among their offspring = 1/4
Probability of no dimples and a non-cleft chin = 1/4
Explanation:
the allele for the dimple trait D is dominant over the allele for the non-dimple trait d.
the allele for the cleft chin trait C is dominant over the allele for the non-cleft chin trait c.
Mr. Smith has heterozygous alleles for both traits.
Mrs. Smith does not have dimples, nor does she have a cleft chin
Mr Smith DdCc x. ddcc
Probability of Dimples and a cleft chin among their offspring = Dd x dd = 1/2
Cc x cc = 1/2 = 1/2*1/2 = 1/4
Probability of no dimples and a non-cleft chin = Dd x dd = 1/2, Cc x cc = 1/2 = 1/2*1/2 = 1/4.
Autotroph: a creature that obtains its carbon from inorganic carbon dioxide
Chemotroph: an organism that obtains energy from chemical substances-Heterotroph: an organism that must receive its carbon in an organic form
Phototroph: an organism that produces energy from sunlight
The term "primary nutritional groups" refers to a category of creatures that are separated into subcategories based on the sources of carbon and energy that they require for survival, growth, and reproduction. Carbon can come from organic or inorganic sources, and energy can be derived from either light or chemical molecules. ATP, carbs, or proteins are used to store the liberated energy as potential energy. The energy is eventually put to use for activities essential to life, like movement, growth, and reproduction.

<span>Here is the correct option: 'Manatees needs only a few things to survive up to age 60: enough food and to be left alone'. In writing, a colon usually precedes an explanation. Colons are used in English writing to introduce a list of items. In the given example, colon was used to list the needs of Manatees.</span>
