Feeling pain, hunger, thirst, sleepiness, and being aware of our thoughts and emotions are all examples of Internal stimuli.
The Mitochrodria helps break down sugar and turns it into energy
Answer No 1:
The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.
Answer No 2:
The outcomes of each possible genotype are:
OOTT = 2/16
OOTt = 4/16
OOtt = 2/16
Oott = 2/16
OoTT = 2/16
OoTt = 4/16
Answer No 3:
The likelihood of each possible offspring phenotype is:
Orange petals with tall stem and orange petals with small stems present in ratio 12:4 i.e. 3:1.
Answer:
See the answer below please.
Explanation:
There are different types of mutations:
- Substitutions: the exchange of one base for another occurs (eg changes a C for an A), which could lead to a codon change that codes for a different amino acid causing changes in nascent protein, generating a codon that codes for the same amino acid without any change in nascent protein; generate a different codon for the amino acid: a stop codon and cause an incomplete protein to form.
-Insertions: base pairs are added to the DNA sequence.
-Deletions: base pairs are removed from the DNA sequence.
It has 3 layers
an animal cell has no cell wall but a plant cell dose
it protects,support, and gives the plants their shape
