Some sphinx moth caterpillars are called tomato hornworms. These large caterpillars do a tremendous amount of damage to tomato plants. Which method of moth control would be most dangerous to the honeybee, which is needed for plant pollination?.
Answer:
Spraying plants with insecticides
The method of moth control would be most dangerous to the honeybee, which is needed for plant pollination is spraying plants with insecticides.
What is pollination ?Pollination is the transfer of pollen from a plant's anther to its stigma, allowing fertilization and seed production, most commonly by an animal or by wind.
Pollination is the transfer of pollen grains from stamens, the flower parts that produce them, to ovule-bearing organs or to the ovules (seed precursors). Pollen is simply caught in a drop of fluid secreted by the ovule in plants where the ovules are exposed, such as conifers and cycads.
Pollination is the process of moving pollen grains from the anther to the stigma of the same or different flowers. Self-pollination and cross-pollination are the two types of pollination.
Thus, The method of moth control would be most dangerous to the honeybee, which is needed for plant pollination is spraying plants with insecticides.

nich conclusion is supported by the data?
As the concentration of sugar decreases, the environment shifts toward aerobic conditions.
As the yeast breaks down sugar, it slowly releases more oxygen into the environment.
As the concentration of carbon dioxide increases, the environment shifts toward anaerobic conditions.
As the yeast noduces more carbon dioxide, it releases less sugar into the environment.
The conclusion supported by the data is that as yeast produces more carbon dioxide, it releases less sugar into the environment.
How do yeasts work in fermentation?Through fermentation, yeasts break down the glucose molecule to produce energy for your cell. In this process, carbon dioxide and alcohol are formed, favoring the production of products such as bread and alcoholic beverages.
Whit this information, we can conclude that the conclusion supported by the data is that as yeast produces more carbon dioxide, it releases less sugar into the environment.

Select all that apply. Astrocytes participate in the formation of the blood-brain barrier. Oligodendrocytes act as stem cells, producing neurons and glia. Schwann cells myelinate dendrites in the PNS.
The correct statement about glial cells and their function is given below:
Astrocytes participate in the formation of the blood-brain barrier.What do you mean by Glial cells?Glial cells may be defined as any of the cells that hold nerve cells in place and help them.
Astrocytes may even form barriers to the spread of neurotransmitter substances released as synapses. It tends to participate in the composition of the blood-brain barrier.
Oligodendrocytes are responsible for the formation of the myelin sheath of nerve fibers in the cells.
Schwann cells myelinate axons not dendrites in the PNS.

its due today pls answer <333
Answer:
B
Explanation:
Every balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it ca only be transformed from one form to another form.
In a chemical reaction, total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
During a chemical reaction, the atoms on the reactant side must also be present on the product side.
For the given reactants, the chemical equation will follows:
As, the reactant side contained carbon, hydrogen and oxygen atoms only. So, the product will also contain the same atoms.
the correct answer is Option B.
Deforestation is the clearing of Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world's land area, but swaths the size of Panama are lost each and every year. Deforestation on such a large scale has a dramatic effect on the carbon cycle. Which of the following describes the effect large scale forest clearing will have on the carbon cycle.
Answer: B
Explanation:
the less trees the more carbon
Large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.
What is deforestation?Forests are important for the carbon cycle because they absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass and in the soil. When forests are cleared or burned, the carbon stored in the trees and soil is released into the atmosphere as carbon dioxide, contributing to greenhouse gas emissions and climate change. In addition, deforestation can disrupt the water cycle, leading to changes in rainfall patterns and soil moisture
Hence, large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.

Which cell helps to move dust particles out of an organism? A ciliated cell B guard cell c muscle cell D red blood cell
Answer:
A) A ciliated cell
The cells that help to move dust particles out of an organism are known as red blood cells. Thus, the correct option for this question is D.
What is the function of Red-blood cells?The function of Red blood cells is determined by the fact that they carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
The amount of carbon dioxide that is accumulated in the body of an individual may be said to be a waste product because it is usually formed as the byproduct of several metabolic processes. Apart from carbon dioxide other waste products may also form in the body which is moved out of organisms with the help of red blood cells.
