Answer:
Asexual reproduction.
Explanation:
The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.
Answer:
Tropomyosin
Explanation:
The calcium binding to troponin and induces the muscle contraction. The active binding site gets exposed due to the calcium binding.
The calcium ions then attaches with troponin molecule. This changes the shape of troponin and removes the tropomyosin protein from the binding site. No ATP is available during this process.
Thus, the correct answer is option (d).
Answer:
They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.
Explanation:
As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.
To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.
Answer:
A cell is basically made of biological molecules (proteins, lipids, carbohydrates and nucleic acids). These biomolecules are all made from Carbon, hydrogen and oxygen. Proteins and nucleic acids have Nitrogen.
Explanation:
Answer:
b the turgor pressure will increase but the cell wall prevents the cell from exploding
Explanation:
The plant cells are exposed in a change of pressure liquid depending the quantity of solids that are inside and outside the cell. Like in this case, the hypotonic solution is the one that has less solids outside the cell, that is the reason why the water enters the cell to equilibrate the concentration of solids inside and outside the cell.
