Answer:
the correct option is: 3. Hormones that interact with plasma membrane receptors that have a hormone binding site outside and an enzymatic activity on the cytosolic side, with ligand binding stimulating that activity.
Explanation:
There are about 200 differentiated cell types in humans, only a few produce hormones, but most of the 75 trillion cells in a human being are targets for one or more of the more than 50 known hormones. The target cell concept is a useful way to analyze hormonal action.
The cells have protein structures on the surface, where they are hormone-ligand, this generates different signal activation pathways inside the cell, through ion channels, g proteins, increase in internal cAMP, and other mechanisms.
Answer: Discrimination.
Explanation:
In social behavior, discrimination is any action or omission made by persons, groups or institutions that produces and reproduces inequalities in access to resources and opportunities as different as food, health services, work, education or employment, in favor or against other persons, groups or institutions. So, it is the act of separating or forming groups of people based on certain criteria. It refers to the violation of human rights equality by age, color, height, abilities, ethnicity, family, gender, genetic characteristics, marital status, nationality, race, religion, sex, and sexual orientation. And, in moral philosophy, discrimination has been defined as "disadvantageous" treatment or consideration.
Discrimination is not new; throughout human history, other individuals have always been discriminated against because of their resources, their origins or intelligence, and even entire peoples because of their different ideas about religion or politics. Most people affected by discrimination are individuals belonging to so-called minorities, small groups within a society, although there are many cases where these groups are not small.
Explanation:
The rock cycle is powered by the internal and the external heat engines.
The sun is the ultimate source of energy that drives surface processes.
The heat from radioactive decay, frictional heat, accreted heat during the formation of the earth all combines to drive subsurface event.
- Surface events that impacts the rock cycle are weathering, erosion, transportation and deposition of sediments.
- Surface events leads basically to the production of sediments.
- The agents that drives the production of these materials are the wind, water and glacier.
- The sun is the major drive for the formation of these agents.
- The process leads to the formation of sedimentary rocks
For the subsurface process, the internal heat engine provides the energy that powers the convection current within the mantle.
This process leads to the formation of igneous and metamorphic rocks.
Where plates diverges and converges, igneous rocks form due to the upwelling of magma.
At convergent margin, a subduction zone allows for the changing of rock type into a metamorphic one. This is due to the temperature and pressure in those areas.
