Answer:
hemoglobin
Explanation:
Cytoplasm of RBCs contain large amount of hemoglobin which contain iron binds to haem group. it carry and transport oxygen from lungs to all parts of body and return carbondioxide back to the lungs from the different tissues.
Normal level of hemoglobin for men= 13.5 to 17.5 g/dl and for women =12.0 to 15.5 g/dl
Low level of hemoglobin is the indication of anemia
Answer: (c) A local wolf population experiences a lethal epidemic of parvovirus.
Explanation:
A limiting factor is one which is capable of limiting the population of the species. It can be a living factor or a non-living factor.
The density dependent limiting factor is a factor which affects the population of a species depending upon the size of the population. There are many density dependent limiting factors such as disease, migration, predation and food.
C is the correct option, this is because of the fact that the epidemic outbreak can spread over to the large number of members of the population. If larger the population size more likely will be the chances of spreading.
Answer:
Erythrocytes is the answer
The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction.
Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction.
Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation.
The answer is C, hope it helps!
Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
