Answer:

A scientific investigation is a plan for asking questions and testing possible answers. A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.

Explanation:

The process of science involves asking a question and then forming testable hypotheses in order to gather evidence either to support or to refute it. So-called "cherry picking" of evidence to support an idea and ignoring evidence that may refute it does not advance knowledge and is not the scientific method.

The force required to prevent the movement of water across a selectively permeable membrane is __________ pressure
SOVA2 [1]

The force required to prevent the movement of water across a selectively permeable membrane is osmotic pressure. The plasma membrane forms a vesicle around the substances to be transported, and the vesicle around the vesicle is taken into cells.

Osmotic pressure depends on both the pressure gradient and concentration gradient.  This is only affected by the temperature and concentration of solute, each affect the movement of water across a membrane.

Higher the concentration is higher temperature increases osmotic pressure, which produced or associate with osmosis and dependent on molar concentration and absolute temperature. Hydro-static pressure forces fluid out of the capillary , osmotic pressure draws fluid back in.

The release of an inorganic phosphate from the myosin molecule directly results in ________
zhuklara [117]

Answer:

power stroke

Explanation:

  • The process of muscle contraction requires several steps.
  • The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
  • However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
  • For the movement of myosin, it binds and releases actin and forms cross bridges.
  • Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
  • An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

Why are colonial organisms not truly multicellular?​
Alborosie

Answer:

Colonial Organisms

The difference between a multicellular organism and a colonial organism is that the individual organisms that form a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot. This enables the colony to swim towards the light.

Explanation:

All based on research.
