Cell membrane helps to enclose the cell organelles and cytosol inside a cell. ... A cell wall is a ridgid, protective layer and it covers the cell membrane. For plants, cell walls are mainly made up of cellulose, while a cell wall in bacteria is made up of peptidoglycan,and for fungi it is made up of chitin.
Answer:
None of the birds have the same niche.
Explanation:
They all have different niches because of the food they ate. Over time, they were gentically changing to adapt to their own food.
Answer:
A
Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
Photosynthesis
Photosynthesis is the production of ATP through the conversion of energy from sunlight using chlorophyll.
Chlorophyl is found in plants, and plants use sunlight to make energy.
That energy is in the form of ATP.
<u>Answer:</u>
<em>If there is too little ACTH produced by the pituitary gland the level of cortisol produced would be less.
</em>
<u>Explanation:</u>
Addison’s disease is a primary adrenal deficiency and n people with this disease the <em>pituitary gland produces very little adrenocoticotrophic hormone generally called ACTH. </em>
Production of cortisol depends on the levels of ACTH produced by the pituitary. Cortisol is a steroid hormone produced by the adrenal gland. <em>Cortisol maintains the blood pressure and regulates the levels of glucose and protein. </em>
When the level of ACTH goes down the level of cortisol also goes down. People with <em>addison’s disease show symptoms like weight loss, abdominal pain etc.
