Answer:
The passive transport of a substance by its concentration gradient through a protein channel is called facilitated diffusion.
Explanation:
Facilitated diffusion is a type of passive transport through the membrane, which involves the use of integral proteins called protein channels or transport proteins, and moves substances unable to cross the membrane by simple diffusion.
An example of facilitated diffusion through protein channels is the ion channel. Ions, being electrically charged particles, cannot pass through the plasma membrane. A protein channel -which crosses the whole thickness of the membrane- constitutes a space where ions can move depending on their concentration gradient.
In facilitated diffusion, both protein channels and transport proteins do not require energy, so it is a transmembrane passive transport process.

Anna wanted to see what battery lasted the longest. She put each battery into a clock and recorded the time that the clock stopped. She used Duracell, Energizer, Kroger brand, and EverReady. Independent Variable (IV): _Type of clock_____________________________________________ __________________________________________ Dependent Variable (DV): ______________________________________________ Control: _____________________________________________________________ Constants:____________________
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock
Explanation:
Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.
Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY
Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.
Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock

4. How is exponential growth possible?
1. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
2. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
3.Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems. (Not from google )
Answer:
1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.
Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.

Describing Water Molecules Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply. Water molecules are polar. Water molecules are nonpolar. Water molecules undergo hydrogen bonding. Water molecules have a linear geometry. Water molecules have a bent geometry.
Answer: These are the correct answers...
-Water molecules are polar
-Water molecules undergo hydrogen bonding
- Water molecules have a bent geomtry
Hope this helps whoever needs it
The statements that are correct about water molecules are:
Water molecules are polar. Water molecules undergo hydrogen bonding.Water molecules have a bent geometry.Water is polar molar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).Water molecules forming hydrogen bonds with one another.Water has a bent shape is that the two lone pair of electrons are on the same side of the molecule.Learn more:

Which of the following best describes the motion of the object in this p-t graph
Answer:
I think its the third one should be
Answer:
The graph above shows that the position of the body is changing with time exponentially and it is accelerating. The velocity of the body is changing with time and as a result the distance it is covering per time will be changing. Generally the graph of positions against time for a body that is accelerating will always look like the diagram above. For constant velocity motion, the graph will be a straight line with slope equal to the velocity of the body.
Explanation:
The velocity - time graph will for a undergoing the motion described by this graphics will be a straight line graph with it slope equal to the acceleration of the body.

Which is most directly responsible for water’s unique properties
It's Hydrogen Bonds
Explanation:
Water has some unusual properties due to its hydrogen bonds. One property is cohesion, the tendency for water molecules to stick together. The cohesive forces between water molecules are responsible for the phenomenon known as surface tension.

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem
Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.
Explanation:
hope it helps :)
The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:
The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.
The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.
The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.
The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.
Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.
In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.
On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.
Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

Answer:
The answer is D.
Explanation:
Feel free to mark brainliest.
Answer:
The cones provide protection to seeds from animals and the environment.
Explanation:
Cones attract animals that will help with plant reproduction. (no, because no animals are attracted to pine cones)
Cones are used to as food source for the plant. ( no because food is not stored in it, the seeds are, plants don't eat their own seeds)
The cones catch rainwater for the tree to use. (no! which tree is going to suck water from their cones?)

find cos A if sin A=3/5
Explanation:
for sin we divide the opposite by the hypotenuse
and for cos we require the adjacent divided by hypotenuse
we can get it through
a²+ b²=c²
ur unknown in this case is the adjustment which you can either substitute with a or b
a² + 3²=5²
a²=5²-3²
a²= 25-9
a²= 16
[tex] \sqrt{a ^{2} } = \sqrt{16} [/tex]
a=4

what is the point on an object where the force of gravity is considered to act A. center of mass B. top of an object C. middle of the object D. center of gravity
Answer:
D. Center of gravity.
Explanation:
Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.
Answer:
D. center of gravity
