Answer:

Gene therapy

Explanation:

Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

Answers

Answer: D

Explanation: This is because I just know. I toke Biology and learnt that's it's D trust me.

Fish, reptiles, birds, and reptiles all belong to the Phylum vertebrate of Animal Kingdom. All these organisms have a vertebral column. Thus, the correct option is D.

What is Cladogram?

A cladogram is a diagram which is used in cladistics to show the relationship among different organisms present in the ecosystem.

A cladogram is not an evolutionary tree as it does not show how ancestors and descendants are related to each other and who are the ancestors.

Fishes, reptiles, birds, and reptiles are the species which belong to Phylum Vertebrata. All these organisms show organ-system level of organization, vertebral column, closed circulatory system, body coelom, etc.

Therefore, the correct option is D.

Explanation:

Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.

Synthesize enzymes from organic molecules

The option (C) is correct. Synthesize enzymes from organic molecules.

What are enzymes?

Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

Moreover, enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

Therefore, enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced naturally in the body and help with important tasks, including: building muscle. destroying toxins.

Name the four ways muscle strength can be measured and briefly describe each, In this ansignment, you will expand your knowledge of muncle structure and numction by exploring muscle strength and contraction. Then you will no what you learn to answer some follow up questions Read the article and use the information to anwer the following questions​

Answers

Hii!! (: The correct answers are:

Absolute strength measures maximum force.

Dynamic strength measures repeated motions.

Elastic strength measures exertion of force rapidly.

Strength endurance measures fatigue resistance.

Muscle strength can be measured in four different ways: manual muscle testing, isokinetic testing, isometric testing, and dynamometry. Manual muscle testing involves the use of a hand-held dynamometer to measure the amount of force generated by a muscle contraction.

What is the use of this test ?

This type of test is often used to assess the strength of a person’s muscles in order to diagnose any physical impairments or evaluate the effectiveness of a rehabilitation program.

Isokinetic testing is a type of testing that measures the amount of force generated by a muscle contraction at a constant speed. This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program.

Isometric testing is a type of testing that measures the amount of force generated by a muscle contraction when the muscle is held in a static position.

This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program. Finally, dynamometry is a type of testing that measures the amount of force generated by a muscle contraction when the muscle is actively contracting.

This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program. These four different methods of measuring muscle strength can provide valuable insight into the strength and function of a person’s muscles.

Hence, Manual muscle testing is the most commonly used method, as it is the most cost-effective and can provide quick results. Isokinetic, isometric, and dynamometry testing are more expensive and time consuming, but provide more detailed information about the strength and function of a person’s muscles.

list and describe three factors that affect how quickly enzymes can work to catalyze reactions

Answers

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

Why does the organism engage in dormancy, hibernation, or migration?

Answers

Answer For,

Why does the organism engage in dormancy, hibernation, or migration?

Explanation:

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy.

Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time. Typically, animals hibernate in order to survive long periods when food is scarce.

Some animals travel relatively short distances to find food or more favorable living or breeding conditions. Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.
