Answer: green algae
Explanation:
Alga is classified as plants as it contains chlorophyll. But, it lacks true stem, roots etc. It is a large group of aquatic plants. Algae could be unicellular, multi cellular or colonial.
A unicellular contains single cell where as multi-cellular consists of of many cells. Kelp, Plankton and Brown algae are multi-cellular where as green algae can be either unicellular or multi-cellular.
I think it is organic compounds
Answer:
The correct option is B. The offspring will inherit neither the genotype nor the phenotype change.
Explanation:
Any changes which occur in the DNA sequence of a person are termed as mutations.
Mutations will only be transferred to offsprings if the mutated gene or sequence gets incorporated into the genome of the mutated person.
In the above scenario, the mutation is just changing the person's phenotype and it has not been incorporated in the genotype of the affected person. Hence, the offsprings will not inherit the mutation, nether in their genotype nor the phenotype.
Answer:
B. F1
Explanation:
Plants used in first-generation crosses were called P, or parental generation, plants (Figure 8.3). Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
Answer:
a. Hormones can persist much longer than electrical signals
Explanation:
Althought hormonal response is slower than electrical signals it affects a large number of organs and sistems. Example: electrical signals are for the openening or closing channels of sodium/potassium wich causes ionic differences on the cells producing quick reponses like movement or blood pressure changes. Meanwhile hormonal response control larger sistems and more complex process like pregnancy
