Hockey is a sport in which players use hockey sticks to push a puck across smooth ice. At practice one day, three different-colored hockey pucks were sliding on the ice. The green hockey puck has less mass than the black and purple hockey pucks, which have the same mass. A player hit each hockey puck with a stick, but not from the same direction. Use the information in the diagram to answer.
Which puck(s) experienced the strongest force when hit? How do you know?
A. All three hockey pucks experienced the same force because they changed speed by
the same amount.
B. The black hockey puck; it is more massive and has the fastest ending speed.
C. The purple hockey puck; it takes a stronger force to slow down a more massive object than to speed it up.
D. The black and purple hockey pucks; they have more mass than the green puck, but changed speed by the same amount.
Answer:
the answer is c
Explanation:
Answer:
Smooth ice reduces the unbalanced forces that would slow the hockey puck. So the answer is C.

What is the relationship between kinetic energy and thermal expansion?
Answer:
These molecules are always in motion and higher temperature gives them more energy and they vibrate more rapidly and hence have higher kinetic energy. One effect of this rapid motion (high kinetic energy at higher temperatures) is the expansion observed, when we heat a substance.
Hope this helps.
A study was conducted to understand the factors controlling the rate at
which molecules or ions travel across cell membranes. An artificial
membrane was created that was composed of a phospholipid bilayer only.
The speed at which various substances crossed this membrane was
measured. Some substances can pass through an actual cell membrane
much faster than they passed through the artificial membrane in this study
Which of the following statements best explains this finding?"
Actual cell membranes have a much thicker phospholipid bilayer than the artificial
membrane does
Actual cell membranes have a variety of proteins embedded in the membrane that are
absent in the artificial membrane
Hydrophobic substances spend more time between the two layers of phospholipid in
the artificial membrane than they do between the layers in an actual membrane
Hydrophilic substand spend more time attached to the polar region of the
phospholipids in the artificial membrane than they do attached to the polar region of
the phospholipid in an actual membrane

What is Isotonic solution??
Answer:
An isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If these two solutions are separated by a semipermeable membrane, water will flow in equal parts out of each solution and into the other.
Answer:Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.

Choose the answer below that has the HIGHEST chance of becoming a fossil. * O A jellyfish in the ocean. O A fern growing in a swamp. O Dinosaur tracks in snow. O A rabbit killed by a fox in the woods.
Answer:
A rabbit killed by a fox in the woods
Explanation:
A fossil is the preserved remains or traces of a dead organism. The process by which a fossil is formed is called fossilisation. After an animal dies, the soft parts of its body decompose leaving the hard parts, like the skeleton, behind. This becomes buried by small particles of rock called sediment.

is something that RESTRICTS the growth of a population in an area and prevents it from going past a certain amount
Answer:
Limitations in the niche or habitat, like disponible food or oxygen saturation.
Explanation:
The limitation of food is the most common way to limit the growth of a population, because without food, the individuals will die in a intraespecific competition.
In other side, the oxygen saturation is a more common way to limit growth aquatic organisms, whom needs O2.
Food and oxygen saturation are into the niche of a living being. The niche is the way a living being lives, which means that a niche envolves the disponible food, places for reprodution, etc.
All what limited the growth of a specie is inside its ecological niche.
Besides that, the habitat is the place where the organisms leaves. The possible activity of a niche depends on the habitat it lives.
Answer:
Limiting Factors
Explanation:
Limiting factors are both biotic and abiotic influences that restrict the growth of a population
Examples of abiotic limiting factors include the physical space that organisms occupy (is it big enough?) and the amount of sunlight (is there enough sunlight for plants to efficiently perform photosynthesis to support the consumers of the ecosystem.
Examples of biotic limiting factors include the availability of food (is there a large enough food source to sustain a large population?) and the presence of organisms that compete with the resources

When the moon's shadow covers part of the earth it is called
a.Eclipse
b. Full moon
c.New moon
d.All of the above
Answer:
A
Explanation:
The light from the sun is blocked by the moon, causing the earth to appear dark during the day.
Answer:
a. Eclipse
Explanation:
When the moon comes between the Earth and the Sun, it blocks the sunlight from reaching the Earth's surface and creates a shadow. This is called an eclipse.
Full moons and new moons are just names for different moon phases. A full moon is when the Sun's light is reflected off the entire surface of the moon which gives it a "full" appearance, while a new moon is the exact opposite and the moon will be completely dark. Neither of these cast a shadow onto the Earth.

1. Define Chemosynthesis?
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
2. List some organisms that undergo Chemosynthesis?
Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.
3. Which organisms conduct photosynthesis?
Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
4. Define photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
5. Type out the chemical equation of photosynthesis?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Answer: 1?
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria.
2? Why is chemosynthesis important? Chemosynthetic deep-sea bacteria form the base of a varied food web that includes shrimp, tube- worms, clams, fish, crabs, and octopi.
3? Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
4? the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
5?The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

A stroke occurs when a blood vessel in the brain becomes blocked or ruptures. One possible symptom of a stroke is the loss of the ability to speak normally.
Based on this symptom, which type of tissue in the brain is most likely affected by a stroke?
connective tissue
epithelial tissue
muscle tissue
nervous tissue
IM TIMED
The type of brain tissue most affected by stroke: Nervous tissue.
The brain is a complex organ that controls thought, memory, emotions, touch, motor skills, vision, breathing, temperature, hunger, and all the processes that control our body. Together, the brain and spinal cord, which extend from the spinal cord, make up the central nervous system, or CNS.
The brain can be divided into three main units: the forebrain, midbrain, and hindbrain. The hindbrain contains the upper part of the spinal cord, the brainstem, and a folded tissue ball called the cerebellum. The hindbrain controls important bodily functions such as breathing and heart rate. The brain is made up of three main parts: the cerebrum, cerebellum, and brainstem. Cerebrum: The largest part of the brain, consisting of the right and left hemispheres. It performs higher functions such as interpreting touch, sight, and hearing, as well as language, reasoning, emotion, learning, and fine movement control.
