Natural and biological control :
The balance of nature depends on the activities of parasites and predators, the majority of which are species of insects. Researchers use this concept in biological control, and have been dramatically successful in many programs.
Silk :
The recognition of silk as a valuable product dates back to China, arguably in the year 2640 B.C. Presently, China annually produces some 30,000 tons of raw silk, which accounts for 80 percent of the world's supply. Most silk is produced from the cocoons of the Silkworm.

Answer:
For gathering unwanted weadsWhy would blood volume play a role in the amount of time a mammal can stay under water?
Answer:
The answer is that they store oxygen in their blood, and in their muscles rather than in their lungs. Marine mammals have a very high blood to body volume ratio. The mammalian diving reflex allows mammals to lower their heart rate and ultimately survive submersion in water for extended periods of time.
Explanation:
The reason why blood volume played a vital role should be explained below.
Role of blood volume:In the case when the oxygen is stored in the blood & in their muscles instead of their lungs so this represents the role of blood volume. Also, marine mammals contain a high blood-to-body volume ratio. It permits the mammals for lowering the rate of heart and survive the submersion in the water for extension of the time. This is the main reason.

Exponential population growth happens when: Select all that apply.
There are no sufficient minerals.
There are too many predators.
There are plenty of resources.
No predators are present.
There are no resources.
Answer:
There are plenty of resources.
No predators are present.
Explanation:
There r plenty of resources + no predators
Exponential population growth happens when there are plenty of resources and no predators are present.
What do you mean by Population growth?Population growth may be defined as the change in population per unit of time.
Exponential growth occurs in the population of continuous breeders. For example, some insects, humans, bacteria, etc.
Exponential population growth requires an enormous amount of resources in habitat and no predator influence.
Therefore, exponential population growth happens when there are plenty of resources and no predators are present.

Give an example of how energy transformations are involved in the development of an energy source.
Answer:
Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation.
Energy must obey the laws of thermodynamics.
Thermodynamics is the study of how energy changes from one type to another. The laws of thermodynamics apply to energy and energy conversions.

erale Learning Inc. - All Rights Reserved
Answer:
B. The increase is due to industrial point source pollution.
Explanation:
Pollution is the release of harmful substances into land, air or water. The harmful or toxic substances are called POLLUTANTS. According to this question, a community discovers via analysis that its river is now polluted with small amounts of over 20 different chemicals.
This chemicals is a pollutant that can likely emanate from industrial companies and industries that produces these harmful chemicals as waste. Hence, the increase is due to industrial point source pollution.

The flocks all started with 10 birds. Flock
was the most successful at feeding, so it will have the greatest number in the second generation. Flock
was the least successful at feeding and has shrunk the most.
In this scenario, natural selection is affecting many populations of birds with different beak morphologies, which affects how well they can eat the available foods. Each flock initially consisted of 10 birds, but over many generations, natural selection favored some traits over others, changing the population size.
One flock, referred to as "Flock," had the greatest number of second-generation birds because it was the most successful at feeding. Another flock, known as "Flock," had the worst feeding results and has had the greatest shrinkage.

Your question is incomplete, most probably the complete question is:
The flocks all started with 10 birds. Flock was the most successful at feeding, so it will have the greatest number in the second generation. Flock was the least successful at feeding and has shrunk the most. With three foods available, natural selection has favored Flock , which has increased the most in the first three generations. Meanwhile, Flock has declined the most because its beak was the least successful phenotype for the food available.

harvested by plankton is passed to the primary consumers. Which process in phytoplankton results
in the largest loss of energy that could otherwise be utilized by consumers?
A Movement
B. Homeostasis
C. Excretion
D. Respiration
Answer:
I think it is letter C
Explanation:
Correct me if I am wrong
The correct answer is option D. respiration as producers and other organisms of each trophic level most of their energy lose by metabolic reactions such as cellular respiration.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat as energy flow from one organism to another trophic level are consumed by organisms from the next level.
only 10% of energy transfers to the next trophic level.Regulation of homeostasis of the organisms is also one of the ways an organism loses their energyExcretion or feces is also one of the ways organism lose their energyMost of their energy lose by metabolic reactions such as cellular respiration.

Two forces are applied to the 45kg box as shown the box is smooth surface which statement best describes the acceleration of the box
Question: Two forces are applied to a 45 kg box, as shown. The box is on a smooth surface.Which statement best describes the acceleration of the box? Assuming the diagram is similar to the one attached.
A) The box accelerates at 1.0 m/s² to the right because the net force is 45 N to the right.
B) The box accelerates at 1.9 m/s² to the right because the greater force is to the right.
C) The box accelerates at 3.0 m/s² because the combined forces cause the box to accelerate.
D) The box does not accelerate, because neither force is large enough to move the box.
Answer:
A) The box accelerates at 1.0 m/s² to the right because the net force is 45 N to the right.
Explanation:
From the diagram attached,
F₂-F₁ = ma.................. Equation 1
Where F₂ = Force acting to the rigth, F₁ = Force acting to the left, m = mass of the box, a = acceleration of the box.
Make a the subject of the equation
a = (F₂-F₁)/m............... Equation 2
also from the diagram
Given: F₂ = 55 N, F₁ = 10 N, m = 45 kg.
Substitute these values into equation 2
a = (55-10)/45
a = 45/45
a = 1 m/s²
Hence the box accelerate at 1.0 m/s² to the right because the net force is 45 N to the right. Hence the right option is A.

Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?
Answer:
The majority of ATP will not form.
Explanation:
The poison leaf plant, also known as gifblaar contains fluoroacetic acid, a compound that shut down the Krebs cycle that leads to less production of ATP because Krebs cycle drives the formation of electron carriers. These electron carriers are very important because these electron carriers carry the energy that is used to create a large number of ATP molecules in the final steps of aerobic respiration so we can conclude that majority of ATP will not form due to poison.
