Answer: Option A
Explanation:
A paraphyletic group can be defined as the group of organism that includes the ancestors but not all of its descendants.
There are three kinds of phylogenetic groups that can be understood by the help of the diagram.
The phylogeny can be defined as the diagram which shows the evolutionary relationship of one organism from another.
Other groups are monophyletic groups, parsimonious et cetera which shows different evolutionary relationship with organisms.
Answer:
All of the above are true.
Explanation:
The prokaryotic organisms are the unicellular primitive organism which was formed in the primitive time when the conditions on the Earth were harsh.
The prokaryotes developed the metabolism to survive in the extreme conditions and were recognised as the archaebacteria. These bacteria can tolerate extreme condition like hot temperature called thermophilic conditions. These thermophiles can grow at higher temperature conditions than the eukaryotes.
The thermophiles are non-phototrophic organism as they do not utilize the light energy to produce energy as phototrophic organisms does.
Thus, all of the true is correct.
Vacuole, cell wall, and chloroplast.
Answer:
A. diploid and C. somatic
Explanation:
Humans are diploid organisms and have 23 pair of chromosomes i.e. in total humans have 46 chromosomes.
There are 2 types of cells in humans (1) somatic cells and (2) germ cells.
Somatic cells are normal body cells which are diploid and have all 23 pairs of chromosomes. But, germ cells are special type of cells which are produced by gonads (sex organs). Germ cells are also known as gametes. In females, ovary is the sex organ which produces germ cells named as egg cells while in males testes is the sex organ which produces germ cells named as sperms. Germ cells (egg and sperm) are haploid cells which fuse to form a zygote which is the first cell of next generation. The process of fusion of egg and sperm is known as fertilization which is responsible for restoring diploidy in the progeny which receives half the genetic material from female parent and half the genetic material from male parent.
After the pairs of chromosomes are aligned, anaphase I begins. During this stage, the microtubules, or spindle fibers, pull the homologous chromosomes apart and move them to opposite ends of the cell.
Its called Anaphase when Chromosomes pull apart
