Answer:
They are the same
Explanation:
A membrane pump is a protein embedded within the cellular membrane which helps the cell transport molecules into and out of the cell. The proteins help the cellular membrane's job of being semi-permeable (allowing certain things in and out). Some molecules cannot travel directly through the cellular membrane (ions, large polar molecules) and have to rely on these proteins to get through the membrane. There are two types, channel and carrier protein pumps. Channel proteins allow for simple passive diffusion where as carrier proteins can allow for active transport as they shape/conform in regards to the molecule they are transporting. Both pumps are specific in what they transport.
Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.
Explanation:
Answer: it’s A
Explanation:
Because uni means one and that means unicellular is only made of one cell
Answer:
C, D, E, F.
Explanation:
Fungi are belongs to multicellular eukaryotic organisms. Fungi are heterotrophs in nature they can not make their own food, and they are playing very important role in nutrient cycle in an ecosystem. They can reproduce from both method sexually and asexually. They are also symbiotic associated with plants and bacteria.
Some statements describe about the body structures or functions of fungi are:
C) Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients.
D) Mycelia are made up of small-diameter hyphae that form an interwoven mass, providing more surface area for nutrient absorption.
E) Some fungi can grow as either filamentous or single-celled forms.
F) All fungi are heterotrophs; some species live as decomposers and others as symbionts.
Much like a cell, a virus is able to grow and reproduce in large numbers
A virus is a microscopic nonliving parasite that only reproduces inside the cells of living hosts. Like cells, viruses have the ability to grow and reproduce within the host cell. When a virus infects a host cell, it injects its genetic material into the cell and forces the host cell to produce thousands of similar copies of the original virus.
