When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. In what way is most of the nitrogen fixed by lightning made available for use by plants?aIt is moved by the wind toward dry areas.bIt is incorporated into the exoskeletons of flying insects that eat plants.cIt is inhaled and exhaled by birds roosting in trees during rainstorms.dIt is carried by rain to the soil.

What is a benefit of genetic engineering?A. Does not require any technology
B. Supported by long term research
C. No controversy surrounding its use
D. Can produce non naturally occuring traits

Answers

Answer: Supported by long term research

One of the many benefits of genetic engineering is that it is being supported by long term research which means this area of knowledge has been thoroughly examined and experimented. There are also inevitable minor issues regarding genetic engineering however, it is not big enough to create doubts on what it can do.

Water harvesting, the collection of rainfall and run off for future use, has been practiced for thousands of years; but in some regions where it was previously used it has been forgotten. In countries facing huge problems with land erosion due to runoff, governments have been encouraging the implementation of this technique. The implementation is important for more than pervention of water erosion . What other benefit might water harvesting have in these areas

Answers

In some areas where water harvesting technique is applied, gains benefit in various ways such as water supply for agricultural purposes and another water usage for the day to day activities like for bath, washing, and cleaning.
More importantly, the use of this technique enables the area to have a clean drinking water. Water is safe to drink because it includes filtration.

What is the correct order of processes involving the movement of oxygen from the environment to mitochondria in vertebrates?

Answers

Answer:

a.) ventilation, circulation, cellular respiration

Explanation:

a.) ventilation, circulation, cellular respiration

b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface

c.) ventilation, diffusion in tissues, circulation

d.) circulation, cellular respiration, diffusion in tissues

e.) circulation, ventilation, cellular respiration

Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.

What component of muscle is described as a bundle of actin, mysoin, and other protien filaments

Answers

The component of muscle which is described as a bundle of actin, myosin, and other protein filaments is referred to as a tendon.

What is a Tendon?

This structure falls under the category of connective tissues and is involved in the attachment of the muscles to the bones as they work together in ensuring adequate movement of body part is achieved.

They made up of different types of proteins such as actin, myosin, and other types of protein filaments and are very flexible which helps them absorb pressure.

This is therefore the reason why tendon was chosen as the most appropriate choice.

At which point is G3P removed from the Calvin cycle to be used in the production of carbohydrates?A. During Photophosphorylation
B. During carbon fixation
C. Immediately after reduction
D. Immediately after regeneration

Answers

The answer is C. The Calvin cycle occurs in the stroma o the chloroplast in a plant cell. It involves the dark stage where carbon dioxide is reduced by protons created in photolysis from the light stage of photosynthesis. The 3-phosphoglyceric acid (3-PGA) is phosphorylated by ATP and then immediately reduced by NADPH in the reduction step. After reduction, G3P is formed and exits the cycle. Other G3Ps are regenerated into a ribulose-1,5-bisphosphate (RuBP) acceptor molecule for the cycle to continue.
