Answer:
interspersed, transposon-derived repeats, simple sequence repeats.
Explanation:
In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.
Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are mobile DNA sequences that can migrate to different regions/areas of the genome.
Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.
Answer:
d. anaerobic
Explanation
anaerobic means no oxygen and fermentation occurs when there is a lack of oxygen
The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.
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.
