Answer:
The correct option is option b that is<em> Homo erectus</em> is the common ancestor of<em> Homo neanderthalensis</em> and<em> Homo sapiens.</em>
Explanation:
<em>Homo erectus </em>appears about 2 mya, possibly during the Pleistocene epoch and are considered as direct ancestor of human.They are called as upright man as they use legs for walking without any support.They are thought to be capable of doing certain things like hunting, starting fire,art making, create speech etc.
<em>Homo neanderthal</em> was the most recent ancestor species of modern human as they appear about 40,000 years ago.
They became extinct as they did't fight against environmental hazards and the major cause of their extinction that scientists have claimed that they did't adapt the modern techniques that the modern human does.
Answer:
Passive transport.
Explanation:
The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.
Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.
Thus, the correct answer is option (c).
i believe ur answer would be the First one
Answer:
1.) Sex organs
2.) DNA replication
3.) Sister chromatids
4.) Two identical daughter cells
5.) Late prophase 1
6.) Tetrads
Explanation:
Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.
Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.
Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS
PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.
Once the chromosomes have formed a pair they are called TETRADS
