1) Answer:F<span>iltration occurs in the renal corpuscle.
</span>
Blood that is going to be filtered enters the first part of the nephron, the glomerulus, which is a tuft
of capillary vessels. The glomerulus is inside a "sac" called a glomerular capsule.Together, the glomerulus and the glomerular capsule form the renal corpuscle, which is the filtering unit.
2)Answer: <span>the excess substance is not reabsorbed and will be excreted in the urine.
</span> The kidneys are able to control the amount of that substance that is needed. So, the needed amount will be reabsorbed and the rest that is in excess, will be wasted to form urine.
Answer: Osmosis
Explanation:
"Water makes up a large percentage of the body's cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is osmosis." Source, Quizlet. https://quizlet.com/350562884/cell-homeostasis-flash-cards/
The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
The term that can be used to describe evolution by natural selection is SCIENTIFIC THEORY.
Theory means "the best explanation so far."
Scientific theory is a work in progress. It is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation.
