Answer:
Endosymbionts Co-Evolution...
Explanation:
This is the only main evidence because let say we observe the size of mitochondrial DNA to be 70S and we measure the same for bacteria to be 70S. This means that there was some kind of endosymbiont relationship in ancient past or at origin of complex multi-cellular organisms that caused co-evolution of both of these and it;'s just not a mere coincidence...
Answer:
1. The prosthetic group of hemoglobin and myoglobin is heme.
2.The organic ring component of heme is porphyrin ring.
3. Under normal conditions, the central atom of heme is Iron (Fe2+).
4. In deoxyhaemoglobin the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
5.The central iron atom has six bonds: four to nitrogen atoms in the porphyrin, one to a histidine residue and one to oxygen.
Explanation:
1. The heme is the prosthetic group common to both the hemoglobin and myoglobin. It is made up of a central iron ring.
2. The porphyrin ring is the organic component of the heme that surrounds the iron ring. Its based on a tetrapyrole ring called porphin commonly found in other biomolecules such as cytochrome and chlorophyll in plants
3. Iron (Fe2+) is central to the heme structure. It has the ability to bind to an oxygen molecule at a time. This gives the protein- hemoglobin the ability to bind to 4 oxygen molecules at a time.
4. Deoxyhaemoglobin is simply a reduced form of hemoglobin which has lost oxygen molecule in red blood cells. It is purple blue in colour.
5. In the middle of the porphyrin ring, the iron binds to 4 nitrogen atoms. 2 free binding sites are available on either side of the plane heme structure with histidine surounding the heme molecule.
Answer:
The genotype is BW
Explanation:
Meri Marzo. That is a codominance, where 2 traits are being expressed or shown in an offspring. If black chicken and the white chicken are crossed, there is 100% of probability that they will have an erminette type of chick.
There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer: Option D.
<u>Explanation:</u>
According to the information that has been given in the question, the Walleye has moved from the east river to some other river. Even though the prey that they have for food which is the yellow perch, then also they move from the east river to the other.
The probable reason for this is that the east river might be polluted. The yellow perch might have got adapted to this pollution and making this survival possible. But the walleye could not adapt to it.
