Answer:
Explanation:
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction occurs through fission, budding, and fragmentation.
I believe the type of nutrition that is believed to have come first is Heterotrophic mode of nutrition. Heterotrophic mode of nutrition is a type of nutrition in which animals or organisms depend upon other organisms to survive. All animals and non green plants are heterotrophic organisms. These organisms have to acquire and take in all the organic substances they need for their survival.
Answer:
The skin is made up of four different kinds of cells which are:
Keratinocytes: They form tight junctions with the nerves of the skin.
Melanocytes: These are the pigment producing cells.
Langerhans cells: These are the immune cells of the skin.
Merkel cells: They show some sensory responses.
The blood cell is made up of different cells which are:
White- blood cells: These provide the body with immunity and helps to fight diseases. There are different types of white blood cells which perform various immune functions.
Red-blood cells: Red-blood cells are involved in the travel of oxygenated and de-oxygenated blood.
Platelets: These help in the formation of clots and to stop bleeding during an injury.
Answer:Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.
Explanation:
Frameshift mutation is due to addition or deletion of bases. From that point onwards the reading frame shifts, different set of codons read. Frameshift mutations are likely to change more than one amino acid, infact a completely irrelevant protein with altered amino acid sequence is produced.
Frame shift mutation can lead to thalassemia due to premature chain termination and run-on-polypeptude that are non-functional.
Answer:
See the answer below
Explanation:
<em>Increasing the concentration of the acid means that the number of ions/particles in the reaction vessel has increased. The higher the number of ions/particles, the higher the frequency of collision of these ions provided that the volume of the reactants remains unchanged. </em>
It is just like comparing a densely populated area with a sparsely populated area. You are more likely to encounter people at a higher frequency in a densely populated area when compared to a sparsely populated area.
