Answer:
Phospholipids
Explanation:
Phospholipids are a particular kind of lipid (an oil) that forms a two-layered surface that surrounds and protects all living cells. The phosphates are essential to forming this bilayered structure. This membrane has a semipermeable function that selectively allows some elements and molecules to go in or out of the cell and thus helps maintain the cell in equilibrium.
Answer:
Water initially moves into the root hair cells by osmosis, because the mineral content of the cells is higher than that of the surrounding environment. Thus, a root pressure is established and extends into the microscopic tubes of the xylem.

Explanation:
El informe de Brundtland es un documento desarrollado en 1987 con el propósito de abordar el problema del desarrollo económico y social desde una perspectiva medioambiental, planteando así por primera vez el concepto de 'desarrollo sostenible'. El documento analiza con una mirada crítica las políticas de desarrollo económico que se llevan a cabo sin considerar la sustentabilidad medioambiental. El informe lleva el nombre Brundtland en honor a la primera ministra de Noruega durante parte de 1980, Gro Harlem Brundtland. El documento fue revelador para su época ya que visibilizó el problema del desarrollo económico y social en función de la sustentabilidad de nuestro planeta. Un punto importante a tener en cuenta del informe es que a fines de sustentabilidad medioambiental la población mundial no podría seguir creciendo a niveles exponenciales como los observados actualmente o a fines del siglo pasado, prediciendo que este valor se debería estabilizar en un valor entre los 7.700 millones y 14.200 millones de personas.
Answer:
Explanation:
Irreversible inhibitors are inhibitors whose action are not reversible. They function by modifying enzyme in a covalent way leading to the formation of new functional group.
Irreversible inhibitors are specific to certain enzymes. Examples is inhibitor that are suicidal they makes inhibitor reactive.
Competitive inhibition are Inhibitor that are competitive in nature they resemble one of the substrate of the enzyme and are been bind to by mistake. Example is an inhibitor that resemble folate an enzyme substrate. Enzyme therefore binds to the inhibitor assuming its folate because they are identical.

B. When a pregnant woman is in labor, the body releases hormones that increase the intensity of contractions, which then increases the secretion of the same hormones.
C. When blood sugar concentration is above normal, the endocrine system releases hormones that lower the blood sugar concentration until it reaches a normal level, and the release of the hormones slows.
D. When a person is jogging, the body releases hormones that continually decrease the rate of oxygen supply to the legs.
ANSWER is A
When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
