1 is the right answer okay
<u>Answer:</u>
<em>All prokaryotes and eukaryotes have nucleic acid as the genetic material which stores the hereditary information. </em>
<u>Explanation:</u>
Both eukaryotes and prokaryotes have cell membrane, ribosomes and cytoplasm in their cell. All the prokaryotes and eukaryotes undergo reproduction however, the process might be different. The reproduction can be sexual or asexual.
The size of the prokaryotes and the eukaryotes vary and also the prokaryotes lack well defined nucleus and the eukaryotes have well defined nucleus and the genetic material is stored inside it.
Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
Answer and explanation
There are instances where taking any vitamin or mineral supplements will be unnecessary or even harmful.
Example
a) For children who are already drinking Fluoridated it will be unnecessary to give them Fluoride supplements
b) It is unnecessary to take supplements because you believe it can cure diseases. If you have a disease one should see a doctor
c) It can be harmful to take supplements that increase energy levels inthe body. It can lead to altered heart rhythm and eventually death
d)A doctor should be consulted before taking nutrient supplements such as Vitamin A. Most have a toxicity level and it is not necessary to take them unless there is deficiencies.
Answer:
También se ha debatido el hábitat de la abiogénesis. Si bien alguna evidencia sugiere que la vida puede haberse originado a partir de la no vida en los respiraderos hidrotermales en el fondo del océano, es posible que la abiogénesis ocurriera en otros lugares, como en las profundidades de la superficie de la Tierra, donde las protoceldas recién surgidas podrían haber subsistido con metano o hidrógeno, o incluso en el océano. costas, donde los proteinoides pueden haber surgido de la reacción de los aminoácidos con el calor y luego entrar al agua como gotitas de proteína parecidas a células.
