The main difference between haploid and diploid cells is the number of chromosome sets found in the nucleus. Diploid cells have two sets while haploid cells only contain one set.
Answer:
They are necessary for co-ordination.
Explanation:
The both systems brings about co-ordination, thought there are some basic differences between them. Many organs in an animals system have organs to carry out activities like locomotion, digestion, respiration and excretion. The activities of each organ system must be co-ordinated with those of other systems; and with conditions in the external and internal environments of the animal.
Unlike the endocrine system, the nervous system works rapidly. Messages are carried mainly as electric impulses along nerves triggering immediate response from target organs.
The hypothalamus is the important link between these two systems.
This is your perfect answer.
Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). Only the parts that were green become blue/black with iodine solution, showing the importance of chlorophyll in photosynthesis. ... This is evidence that chlorophyll is required for photosynthesis.
which of these levels of biological organization contains the other three:
C) Body System
Hippodamia convergens and Hippodamia variegata can mate but cannot produce fertile offspring because the number of chromosomes can make the development of the embryo unfeasible.
<h3>What are fertile hybrids?</h3>
The crossing between plants or animals of similar species can generate beings that, despite being hybrids, are fertile, even though in the initial phase of cell multiplication some chromosomes do not find the respective pair.
<h3>Why don't hybrids reproduce?</h3>
These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male is necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies.
With this information, we can conclude that Hybrid animals are beings from genetic crosses between different species, but of the same genus, that is, when two different animals cross and a new animal appears, usually sterile, due to their incompatible genes: the hybrid animal.
