when muscles contract, the ____ energy of ATP is used to drive the ____ energy of contraction

Answers

Answer 1

Answer:

1. Chemical energy

2. Mechanical (kinetic) energy

Explanation:

The contraction of our muscles is accompanied by movement. Contraction of muscles involves the proteins myosin and actin, which forms a cross-bridge. Calcium ions bind to troponin protein allowing the myosin to bind to the binding sites on the actin protein.

However, for this cross-bridge cycle between myosin and actin to occur repeatedly, ATP is needed to induce the release of the myosin from the actin active site. Therefore, When muscles contract, the CHEMICAL energy of ATP is used to drive the MECHANICAL energy (kinetic energy) of contraction.

NOTE: ATP supplies chemical energy to induce movement of muscles during contraction. Energy due to motion is called KINETIC ENERGY.

Answer 2

When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction ;  The missing answers are ; Chemical and Kinetic

When we contrast our muscles ATP induces the release of  myosin from its actin active site ( i.e. the use of the chemical energy contained in ATP ). the release of myosin leads to the contraction of the muscles, which is a form of mechanical/kinetic energy. The proteins involved in the contraction ( kinetic energy ) of muscles are myosin and actin while the calcium ion involved is troponin.

Hence we can conclude that When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction.

You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.

Answers

Answer:

(a). Yes.

(b). RNA becomes Radioactive.

(c). No.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

Explanation:

So, let us do right into the explanation behind the answers to the questions asked.

(a). The answer to this part of the question is "Yes" because in creating or in the formation of the glycosidic bond, all the alpha phosphate group were taken into consideration that is they were all used, thus making the newly synthesized RNA to be radioactive.

(b). The RNA becomes Radioactive is the answer to this part of this question because CTP is needed in the experiment.

(c). The answer to this part (c) of this question is ''No'' because the only thing that takes part in bonding is the alpha phosphate.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

A. pond
B. estuary
C. wetland
D. stream bed

Answers

Answer:

The correct answer is C. Wetland.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

What is Ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.

Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

Laboratory techniques for randomly linking together amino acids typically generate an insoluble polypeptide, yet a naturally occurring polypeptide of the same length is usually soluble. Explain.

Answers

Answer:

The answer has been explained below

Explanation:

The polypeptide has a natural selection due to an optimized sequence. It folds properly. At the outside it has hydrophobic residues. Inside it has polar residues. Now the random sequence of the synthetic peptide is going to be unable to give a good direction to a folding process. This will cause aggregation of hydrophobic side chains on various molecules. Bringing about the polypeptides precipitation from solution. Polypeptides that occur naturally have have the same length when they are in aqueous solution because of amino acid side chains that are present and are large with reactive functional groups.

The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust disease. Conversely, different strains of flax are resistant or sensitive to the various varieties of rust. The Bombay variety of flax is resistant to M. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flax called 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1 individuals were self-fertilized, the following data were obtained:

43 resistant to strain 22 but sensitive to strain 24
9 sensitive to strain 22 and strain 24
32 sensitive to strain 22 but resistant to strain 24
110 resistant to strain 22 and strain 24

Required:
Explain the inheritance pattern for flax resistance and sensitivity to M. lini strains.

Answers

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

Distinguish between the different ways volcanoes cause damage.

Answers

Answer:

Hi! Your answer is:

The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.

Explanation:

Volcanoes emit deadly gases, ash, lava, and rock. Volcanic eruptions kill. Floods, mudslides, power outages, drinking water poisoning, and wildfires can follow volcanic eruptions, posing health risks.

What are volcanoes?

The pyroclastic flow that results after an eruption of a volcano is known as the volcanic plume. This flow transports significant quantities of ash and rock into the air and along the ground in the area surrounding the volcano. When this ash and rock combines with water, it generates lahars, which are similar to landslides and rush down the slopes of volcanoes like a river, sweeping away everything in their path.

When they hit the ground, the rocks that were thrown into the air by the pyroclastic flow, known as tephra, cause damage to the area where they land. Toxic chemicals that are emitted by fumaroles have the potential to cause acid rain, contribute to air pollution, and reduce the amount of ozone in the atmosphere.
