A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.
Answers
A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

Summer annual crops are known to germinate, flower, produce seed, and die by frost amidst the warmer months of the year.Winter annuals often sprout in the late summer and autumn, it is known to be dormant during the winter, and grow during the next spring and summer. its young winter annual plants live through the winter then flower, set seed and die out the following summer.
Winter annuals often bloom in winter or spring. They grows in very low to the ground. Examples are henbit, deadnettle, chickweed etc. Spring annuals are known to sprout early in the spring.

Answer:
Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Photograph of a coal fire.
Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]
Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.
Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.
Draft diagram of the carbon cycle.
This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)
Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.
This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.
Graph of oxygen isotope ratios in the deep ocean for the past 67 million years.
The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).
What are the steps of carbon cycle?Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.
Carbon is transferred from the atmosphere to plants.Carbon is transferred from plants to animals.Carbon is transferred from plants and animals to soils.Carbon is transferred from living things to the atmosphere.When fossil fuels are burned, carbon is released into the atmosphere.Carbon is transferred from the atmosphere to the oceans.Thus, above-mentioned are the steps involved in a carbon cycle.

Answers
The most likely conclusion that can be made for the change in flower color is that genetic factors caused the differences in flower color.
According to this question, three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow.
However, despite the uniformity in the environmental conditions received by each plant, one plant grew to have a purple flower while the other two grew white flowers.
This difference in flower color is likely caused by the inherent genetic factors of each plant rather than environmental factors because they were treated the same.

C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answers
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
