Answer:
Asexual reproduction is through the formation of asexual spores. They are produced by one parent only and are genetically identical to that parent (Mitosis).
Sexual reproduction in the fungi has three stages plasmogamy, karyogamy, and meiosis.
Explanation:
AR: Spores may be dispersed by moving water, wind, or other organisms. The spores far from the parent organism. This helps to ensure that the offspring will not have to compete with the parent for space or other resources.
SR: Sexual reproduction occurs when spores from two parents fuse and form a zygospore.
neurons are specialized cells that generate and conduct electrical impulses throughout the body.
Answer:
a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.
c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.
d.Mitochondria and chloroplasts replicate by a process similar to mitosis.
Explanation:
Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.
The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
The information is not available regrading the question and its option. The answer will consider the general points regarding the REM sleep in infants.
Answer:
Rapid eye movement (REM) sleep is the sleep that involves the rapid and random movement of the eyes. The muscle tone gets low during the REM sleep. This sleep is present in both infants and adults.
The baby start shows his legs and hands during the REM sleep. Most of the infants experience the REM sleep. The sleep become less active and the individual is more conscious during the REM sleep. The breathing of the infant is quite irregular in REM sleep.
