Cells are classified as prokaryotic when they lack a defined nucleus.
Hope this helps :)
Eukaryotes
<span>Plants normally make their own food by the process of photosynthesis. Plants take in water through the roots from the ground, absorb sunlight during the day and take in carbon dioxide from the air to make their nutrients. So plants are normally autotrophic in nature. Animals on the other hand consume plants as well as other animals to produce nutrients. So animals are mostly heterotrophic in nature. Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme. </span>
Answer:
AaBb
Explanation:
<u>Cross between true breeding strains</u>
Parents: AAbb x aaBB
Gametes: Ab aB
The F1 is homogeneous: AaBb.
<u>To obtain the F2 generation we must do a cross between 2 F1 individuals</u>: AaBb x AaBb
Their genotypes are the same, so they both will produce the same type of gametes: AB, Ab, aB and ab.
If you do a Punnett Square, you can check the ratio of genotypes of the F2, and that the "4" refers to AaBb.
Answer:
A
Explanation:
Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.
