Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects.

Answers

Answer 1

Answer:

Genetically modified organisms (GMOs) have altered their genomes in different ways in order to be resistant to both biotic (e.g., insect pests) and abiotic (e.g., drought) stress conditions

Explanation:

A genetically modified organism (GMO) is any organism, i.e., plant, animal, bacterium, etc., whose DNA has been altered by genetic engineering. The GMO crops can exhibit resistance to insect pests in order to increase their agronomic yields (as well as resistance to other biotic and abiotic stresses). It is for that reason that GMO crops are widely used in many countries. A commercially available GMO crop is Bt corn, which is a genetically engineered maize that expresses proteins from the bacterium Bacillus thuringiensis (Bt), which are poisonous to several insect pest species.

Is it possible for energy to be transferred directly from the first trophic level to the third trophic level? Explain.​

Answers

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

During energy transfer, 10% of the energy is transferred to the next trophic level and 90% is lost to the environment. Energy transfers from one trophic level to the next trophic level and not the third trophic level.

What is Energy transfer?

Energy transfer is the amount of energy at each trophic level which is transferred to the next trophic level. Energy decreases as it moves through an ecosystem. As little as 10% of the energy at any trophic level is transferred to the next level and the rest is lost largely through metabolic processes as heat energy.

From each trophic level to the next trophic level, about 90% of the starting energy is unavailable to the next trophic level because the energy is used for different processes such as movement, growth, respiration, and reproduction and some energy is lost as heat.

Explain why worms have outer skin as their respiratory surface rather then lungs. NO google answer. ASAP

Answers

Hey There!_____________________________________Answer:

The simple answer for that will be that they are not complex organisms. Earthworms are simple organism with the small body,

So as there body is not that big thus they don't need any specialized organ system for the process of respiration. Every organism has the complex systems according to fulfill their needs, and most certainly the skin is very convenient medium for the respiration by the diffusion process.

-------------------------------------------------------------------------------------------------------------

BLOOD CIRCULATORY SYSTEM:

They have a specialized system where it was needed, THE BLOOD CIRCULATION SYSTEM, There body is small but long and need blood to transfer the oxygen to each part of the body. There blood have the haemoglobin(it carries the oxygen), thus it is red just like us.

--------------------------------------------------------------------------------------------------------------

SKIN:

Skin as a respiratory medium, needs to be thin, wet and cover large surface area than volume. The Skin fulfills all these Prerequisites, thus it is a perfect organ for the respiration. Even our respiratory medium which is alveoli is wet, thin and cover REALLY large surface area more than our body. If the skin dries, there will be no diffusion and worm will die due to dessication.

how many monkeys would have to live in a 3/4sq.km. area to have the same population density as the carabao?​

Answers

Answer: 20 monkeys

Explanation:

Question is lacking a very important detail which is the population density of monkeys in the Carabao.

I found that out to be 26.7 monkeys per sq.km

Population density = Number of monkeys / Area

With the population density known to be 26.7 monkeys per sq.km and the area known to be ³/₄ sq. km, the number of monkeys is;

26.7 = No. of monkeys/ ³/₄

No. of monkeys = 26.7 * ³/₄

No. of monkeys = 20

What conclusions can be drawn from the objects that Leeuwenhoek and Hooke observed in
their microscopes

Answers

Answer:

Antony van Leeuwenhoek1 (Fig. 1) found great joy in God’s smallest creatures. He first discovered protozoans in his youth. The Dutch haberdasher retained a child-like joy of discovery from his youth until his death at age 90. He lived to see tiny microbes though his homemade microscopes. He loved to grind and focus a new lens in order to see the unseen world. Leeuwenhoek spent countless hours grinding tiny lenses and looking through them. This Christian lay biologist even used candlelight to see specimens at night. For Leeuwenhoek, the amazing diversity of tiny life forms revealed under his homemade microscopes glorified God as much as looking at stars through a telescope. Leeuwenhoek was born in South Holland in 1632. As a young adult, he became a cloth merchant (also called a draper, or haberdasher). In 1668, he started his biological study as a hobby after seeing beautiful microscopic pictures while making a visit to London. After years of careful study, Leeuwenhoek (Fig. 2) made the microscope famous. In his lifetime, he became the father of microbiology and opened mankind to the world of microorganisms.

HighLighter PopupUnderline Selected TextGreen Color HighlightOrange Color HighlightYellow Color HighlightBlue Color HighlightPink Color HighlightRemove Color Highlight

Answers

Answer:

See the answer below

Explanation:

A greenhouse overheating in the summer months has everything to do with engineering design and must be addressed as such. Since the commercial strawberry grower has already established the problem of overheating of the greenhouses, the solution to the problem lies with checking the engineering design of the greenhouses and not in making a scientific inquiry. The problem has been detected and a solution has to be provided by checking the fault in the design that could be causing the overheating.

Botanists trying to know why a newly discovered species of plant only grows in certain areas would need to carry out a scientific investigation/inquiry in order to get answers to their enquiry. Several questions might be raised as to why the growth of the plant is limited to those areas and these can only be answered by conducting scientific investigations.
