Answer: Vacuole
Explanation:
The vacuole occupies on average 50% of the cell volume, oscillating between 5 and 95%. It is a fluid-filled, membrane-wrapped gallbladder. The vacuoles perform numerous functions because, in addition to accumulating nutrients, metabolites, and catabolites, they serve as deposits of specific substances such as proteins, opium, dairy and also various poisonous or unpleasant taste substances, which protect the plant against its predators.
Vacuoles are structures that participate in the maintenance of cell turgor, which pulls the cytoplasm against the cell wall as air tightens the air chamber against the tire. When water is lacking, the plant wilts due to decreased intracellular turgor.
Answer:
Fewer Offspring than the environment can support
Explanation:
It takes time for a creature to adapt to its Environment. So that puts off 2.
Your guaranteed to get traits from your parents so that rules out #1
There isn't really an equal probability of survival for an offspring, ruling out #3.
So that leaves us with 4. I'm not biology expert, I'm just letting you know how I did this problem. Just in case i'm wrong, I would double check with other answers :)
Answer: Spindle Formation
Explanation:Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved. Cohesin is retained, however, at the most constricted part of the chromosome, the centromere (Figure 9). During prophase, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
Answer: c. Flower
Explanation:
An angiosperm can be define as a group of vascular plants. These plants are flower bearing which means they conduct sexual mode of reproduction through flowers. The flower exhibit male and female reproductive structures the fertilization of which produce seeds and fruits.
If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.
<h3>What is
proton gradient ?</h3>
Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).
For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.
Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.
Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.
