What are four ways that humans harm sea grass? explain in detail.
AURORKA [14]


Pollution; waste and discharge falls into the water, polluting the sea grass. It reduces the amount of sunlight and the plant might die.

Poor land management; trees lead to the erosion of dirt, making the soil cloud up the water, not giving the sea grass sunlight.

Careless behavior; from people stepping onto the sea grass, to other items falling and smothering the sea grass.

PLEASE HELP ME!!!! This figure shows two alleles for the beta-globin gene. The A allele is the most common allele. The S allele
vagabundo [1.1K]

Answer:

The correct answer is option B. The tertiary structure of the beta subunit changes, exposing a hydrophobic cleft which allows hemoglobin to form long chains in RBC.

Explanation:

As it is clearly mention as there is point mutation that leads to single nucleotide change which results in to valine instead of glutamate. Valine is hydrophobic in nature not like glutamate. Valine aggregate and makes a rigid structure of molecules.

Due to this rigid molecule of valine aggregates, RBCs form a crescent or sickle like shape due to the higher viscosity and low solubility of Mutated hemoglobin in deoxy condition. It leads to formation of polymer that blocks the vessels.

Thus, the correct answer is option B.

Explain how the energy investing and energy harvesting steps of glycolysis result in 2 ATP molecules.
Anna [14]

Answer:

There are two-phase of glycolysis preparatory phase and payoff phase. In the preparatory phase, ATP is used therefore it is called the energy investment phase and in the payoff phase, ATP is produced so it is called the energy generation phase.

In preparatory phase 2 ATP is used and it is converted into ADP and in pay off phase 4 ATP is produced from ADP. Therefore by subtracting 2 from 4, we get 2 ATP. Therefore in glycolysis, energy investing and energy harvesting step results into two ATP molecules.
