Answer:
These organelles are contractile vacuoles
Explanation:
Contractile vacuoles are intercellular pumps that are slowly filled with fresh water and eventually expel their contents outside the cell. Freshwater protists maintain the hydric equilibrium by contractile vacuoles that pump out the water of the cell and thus prevent the cell swelling induced by osmotic stress.
Answer:
pretty sure that health scientists, assuming they understand pharmaceutical actions and reactions, get paid either way & possibly get cheaper h insurance for their expertise.
Explanation:
No, does not affect their work because they get paid to test new drugs on lab rats, chimps, dogs, etc. to see if there is an effect on subjects they give a medical condition to. As unfair as it seems, once lab subjects are tested for years, and they witness if they're theories are justified or not; then they determine a trial run on human test subjects. this process can take up 2 10 years or longer.
Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.
Explanation:
Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Answer:
True
Explanation:
Memory is formed by creating new neural pathways from stimuli we receive (smell, vision, auditory etc) to the brain where the pereception of it occurs.
Memory is defined as ability of the brain to encode, store, and retrieve information when needed. Memory forming is actually information processing that includes:
• sensory processor - sensing the information from the outside world ( chemical and physical stimuli)
• Working memory (short-term memory) - encoding (stimuli information) and retrieval processor (from previously stored material)
• Long-term memory - to store data through systems.
