3 0

Answer:

Due to short life cycle and mode of reproduction.

Explanation:

The main cause of the fast growth rate of Eichhornia is their mode of reproduction and shorter life cycle. Eichhornia reproduce through sexually and clonally. Its life cycle is only 10 days means that within 10 days the population of Eichhornia becomes double. It reproduces through sexual reproduction as well as asexual reproduction such as clonally which also contributes for the fast growth of eichhornia plant.

Why was finding a close relationship between mitochondrial DNADNA and bacterial DNADNA considered particularly strong evidence i
kirill [66]

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...

Complete the following sentences about heme by moving the terms to the correct targets Some terms will not be used.
Scrat [10]

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.

choli [55]

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.
