Coniferophyta
Explanation:
Plants and trees belonging to coniferphyta are gymnosperms which are vascular plants with unprotected or naked seeds. These are called conifers because they bear male and female cones produced by the sporophytes on the same tree . The female conifers have many seeds on the cone scales.
These cones have spores which undergoes meiosis and produce male and female gametes respectively. Male gametes with pollen grains produces sperm cells and female gametes produce egg cells inside the ovules.
During the spring season with winds blowing, pollen released from the male cone disperses on the female cone present on the same tree.
Upon reaching the female cone, the sperms in the male gametes will fertilize the egg cells in the female and will fertilize to form zygote. This zygote will develop into an embryo in the ovules and later develop into seeds.
When these seeds fall on the ground, they get germinated into a new conifer. Thus dispersal of the seeds is taken care of by the seeds itself without the production of any fruit.
I believe the response would be D. Increasing the pH within the cell. This may be the case, because through changing the pH of the cell, the enzyme may form new unwanted interactions, which may affect the arrangement and the structure of the active site, which is will affect the ability of the maltose molecules to bind and undergo the breakdown into glucose molecules.
All enzymes work well or optimally within a given or particular pH. Going above or below will cause additional hydrogen bonds that might form, and other interactions affecting function.
Answer:
it is necessary to do the additional trials before conclusion
Explanation:
These additional trials should be the same fertilizer on different plants
Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.
Muscle cells are elongated cells whose length can reach several centimeters.
The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.
Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.
Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.
The muscle cell has three mechanisms to resynthesize ATP:
- ATP synthesis through phosphocreatine.
- Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.
- From oxidative phosphorylation.
ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.
So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.
Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.
