Answer: The diagram attached is known as the nephron,it is labelled from A to E, the structure labelled E which is known as the COLLECTING DUCT can be influenced by hormones to change the concentration of urine.
Explanation: Antidiuretic hormone ADH is one of the hormones that is produced by the anterior lobe of the pituitary gland of the endocrine system,this antidiuretic hormone performs certain functions of which one is that it helps to increase the rate and amount of water that is reabasorbed in the distal convulated tubule of the nephron during the second stage of urine formation,when these water are reabsorbed,the urine being produced becomes more concentrated and there is a further reduction in the volume/quantity of urine produced.
When this volume of urine is decreased/reduced, plasma osmolarity increases in reaction to the decreased volume of urine.
Urine are also reabsorbed in the collecting duct.
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.
Answer:
The conditions for natural selection are:
- overproduction of offspring
- variation among organisms in a population
- favorable adaptations selected by nature
Explanation:
- Natural selection is the continuous process of reproduction and survival that is caused by the contrast and differences due to phenotype.
- Overproduction of species creates the competition and only the one survived through the natural selection grows to the next generation.
- Similarly variations in the phenotypic organization of species, their adaptation process etc causes the natural selection.
- Natural selection is the gateway for the evolution.
Answer:
Cellulose is a polysaccharide consisting of a linear chain of several hundred to many thousands of linked glucose units. Cellulose is an important structural component of the cell walls of plants and many algae.
Explanation:
Answer: Reverse the position of two cells from opposite poles as the blastula stage allow development
Explanation:
An experiment should be performed, this experiment will help to discover the interactivity that exists between cells before reaching the fetal period. The experiment ought to also influence the location of the cells.
