Dorsal means back as in the back area. Example~ Many dolphins have a pronounced beak and all have a central dorsal fin and sharp teeth for feeding, mainly on squid and fish.
Describe how phloem is affected if the leaves start to die off. (3 points) The phloem is effected by the deprivation of water from the disease of the tree, as a result the metabolism of the plant will shift down ward causing the phloem to decrease due to the dying of the leaves.
The correct answers are as follows:
1. During cytokinesis, THE CELL MEMBRANE PINCHES IN TO FORM TWO NEW CELLS.
Cytokinesis is the physical process of cell division, it divides the cytoplasmic content of the parental cell into two new daughter cells. Cytokinesis takes place in both mitosis and meosis.
2. The correct order of the phases of mitosis are as follows: PROPHASE, METAPHASE, ANAPHASE AND TELOPHASE.
Mitosis is the process of cell division by which a cell is divided into two new cells. The process occurs in four basic stages and result in the formation of two new cells.
3. The following terms are related to sexual reproduction: MATING SYSTEM, GAMETE FORMATION AND AMPLEXUS.
Amplexus refers to the mating positions of frogs and toads during sexual reproduction. Mating system refers to the number of mating partners that an animal has during the mating period. Gamete formation is the process by which sex cells are made and it occurs in both male and female animals.
4. As a cell is preparing to divide by mitosis, the DNA MUST BE COPIED.
When a cell is getting ready to divide by mitosis, it will undergo a stage called interphase, during which the cell prepare for cell division. During interphase, the cell undergo some process and these include the copying of the DNA. The cell copies its DNA so that it has two copies of each strand.
I believe the corre term to fill in the blank is "a protein gradient." Chemiosmosis uses a protein gradient to supply the energy necessary to phosphorylate adp to atp. It<span> is the diffusion of hydrogen ions (protons) across the biological membrane via the ATP synthase.</span>
The answer is going to be the letter D, nitrogen. I hope this helps!!
