What are the steps of muscle contraction in order?
The process of muscular contraction occurs over a number of key steps, including:
Depolarisation and calcium ion release.Actin and myosin cross-bridge formation.The sliding mechanism of actin and myosin filaments.Sarcomere shortening (muscle contraction)What is the next step in muscle contraction after calcium ions bind to actin?If present, calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin-binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction.

The diagram below shows a portion of the concept map for the Rock Cycle. What step could occur between sediments and lithification on a concept map of the rock cycle? Which of these would best fit in the empty oval? cooling heating deposition crystallization
Answer:
Deposition
Explanation:
Deposition occur between sediments and lithification. Deposition is a process in which small particles of soil called sediments are added to the land surface. After this deposition, lithification occurs in which the sediments come close together due to the pressure of the sediments that are present above it which reduces the empty spaces and removes the fluid present between the sediments. This process makes the rock more hard.

Which of the following statements is the most likely explanation for plant withering due to leaky membranes in cold temperatures?
A. Too many H+ ions accumulate inside the thylakoid, so ATP synthase makes too little ATP.
B. Too many H+ ions accumulate inside the thylakoid, so ATP synthase makes too much ATP.
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
D. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too much ATP.
Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.

The ADP-ATP cycle is critical to producing cell energy. What do you know about this cycle
Answer:
The overview of the given question is described in the explanation section below.
Explanation:
ADP-ATP seems to be the energy-producing process wherein the energy is generated by transferring Adenine triphosphate (ATP) with Adenine diphosphate (ADP). Because once cell power is consumed, the station started the accessible ATP with ADP and phosphate.Power becomes generated from either the partially decomposed molecule of phosphate. Afterward when ADP has always been transferred to ATP by mitochondria utilizing energy from food.Which selective media can be used to generally screen for gram negative rod?

Biodiversity is the variety of life in an area. Think about the
process of succession. How does biodiversity change during
succession?
Biodiversity increases through the process of succession.
Biodiversity decreases through the process of succession.
Biodiversity does not change during the process of
succession.
Answer:
It Increases.
Explanation:
Biodiversity is the the variety of living organisms such as wildlife and plants. The number of organisms and biomass amount further increases in the ecosystem in which the process of succession is occurring.
The numbers will stabilize when a climax stage has occurred in succession, which will not change the biodiversity.
The sort of many lives living together in an ecosystem or habitat is called biodiversity. Biodiversity increases during the process of succession.
What is succession?Succession is the biological and chemical process of change and formation of the habitat and species of a particular place during a period. It can be primary or secondary.
The formation of the new habitat in barren land is primary succession while the formation of the ecosystem in a once habituated place is secondary succession.
Biodiversity always increases in the succession process till the climax community is not achieved till the conditions are well balanced.
Therefore, option A. biodiversity increase in the process of succession.

Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

What is primary succession?When a new patch of land is created or exposed for the first time, primary succession occurs.
This takes place when lava cools and forms new rocks, or when a glacier recedes and exposes rocks without soil.
Primary succession starts from the beginning, when there was no life. Igneous rock, glaciers, and other natural phenomena are examples.
