Glucose is the primary energy source in animal cells
<span>At four months or five months a baby can pick up large objects, such as building blocks. She won't be able to let go of them easily, though. At six months a baby starts to hone her hand-eye coordination. A baby can rake an object toward herself, and will start moving objects from one hand to the other.</span>
Answer:
a) Genotype of each parent plant= Tt
b) Genotypes of parent plants= Tt and tt
Explanation:
a) In the first cross, the tall and short progeny was obtained in almost a 3:1 ratio (78: 27). This means that both the parent plants were heterozygous for the gene of plant height. The genotype of each of the parents was Tt. A cross between Tt and Tt gives following progeny ratio=
Tt x Tt = 3 tall (1/2 TT and 1/4 Tt) : 1 short (1/4 tt)
b) In the second cross, tall and short progeny was obtained in almost a 1: 1 ratio (121: 118). This means that one parent plant was homozygous recessive (tt) and the other was heterozygous dominant (Tt).
Tt x tt = 1 tall: 1 short.
Answer:
Oxygen
Explanation:
In a molecule of water ie H20, Oxygen is more electronegative and hence attracts more electrons to itself making Hydrogen partially positive ♂️
Answer:
If larger seed became available, directional selection will act in favor of bigger beak finch.
Explanation:
In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed.
Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks.
This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.
