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.

Which of the following biotechnologies is described?
Cloning
Gene therapy
Gel electrophoresis
GMOs
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.

What type of system best. Defines planet earth
Answer:
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Explanation:
Where does most of the oxygen produced in photosynthesis
go?
Answer:
THE ATMOSPHERE
Explanation:
Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules

"Superior vena cava carries completely digested substances"
How far the statement is correct ? With explanation.
Answer:
Yes.
Explanation:
As a blood vessel, Superior vena cava carries completely digested substances that is present in the blood from upper part of the body to the heart. Blood is a fluid that transport digested food from small intestine to other parts of the human body. It also carries oxygen from the lungs to the cells and also carries carbondioxide from the cells to lungs so we can say that Superior vena cava carries completely digested materials.

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
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.

Which of the following properties of carbon distinguishes it from all other elements?
A- Carbon has six protons in its nucleus
B- Carbon is a gray solid at room temperature
C- Carbon forms compounds with oxygen
D- Carbon can be found in Earth’s crust
Answer:
C. carbon forms compound with oxygen .
hope it helps ❤
The property of carbon is that it has six protons in its nucleus distinguishes it from all other elements. Hence. option A is correct.
What are the properties of carbon?The chemical element carbon has the atomic number six and the letter C assigned to it. It has a tetravalent atom, which means that four of its electrons can be used to create covalent chemical bonds. It is nonmetallic. The periodic table's group 14 includes it. The crust of the Earth contains 0.025 percent carbon.
When carbon atoms join together to form lengthy chains, this element can form. When carbon burns, it combines with oxygen to form CO2 (and sometimes carbon monoxide). The incomplete combustion of wood during the creation of charcoal results in a high-carbon product that can burn longer.
Different elements have different numbers of protons in their nucleus. Therefore, option A is correct.

Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. A purple center outlined in black with two concentric black circles around the center, the inner circle having 2 small green balls on it and the outer circle having 8 small green balls on it. What experimental evidence led scientists to change from the previous model to this one?
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
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.

Explain with examples of each, how both physical and chemical weathering, along with erosion, can change Earth's surface.
Answer:
Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.
For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air for chemical weathering.

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.
