Answer:
The answer to this question is given below in this explanation section.
Explanation:
"Alternation of generation"
Alternation of generations is the type of life cycle that occurs in those plant and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.
Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
Hybrid inviability is when a hybrid animal is biologically unable to grow up to be a healthy mature adult. This condition results in isolation from hybrids and pure breeds.
Hybrid infertility is a conditio experienced by hybrid animals when they cannot reproduce. This prevents the spreading of the hyrbid species into uncontrollable populations.
Answer:
In an interval of 5 minutes, ER has ribosomes attached to it which makes proteins synthesizing in the lumen of the endoplasmic reticulum incorporates proteins in the small transport vesicles.
These vesicles transport and fused to the Golgi bodies where proteins modified which can be seen in 15 minutes in the figure. Then modified proteins are transported from the cell cytosol with the help of secretory vesicle to the extracellular matrix and to the required organs.
