The following can be deduced from the life history of bark beetles;

* All bark beetles life stages are spent in the phloem, internal bark, and bark, aside from when grown-ups leave the tree they created in to travel to new host trees. Bark beetles feed on the phloem of their host trees during grown-up and larval stages.

* Many bark beetles travel toward debilitated host trees, be that as it may, during environmental conditions ideal for population improvement, populaces may develop quickly and effectively assault healthy trees.

Explanation:

Bark beetles determine their name since they live and create in the bark and wood of trees and bushes. Grown-ups unearth egg displays in living bark (phloem).

Bark beetles are the most dangerous creepy insects in western coniferous woodlands. It has been assessed that 90% of insects caused tree mortality and over 60% of the complete insect caused loss of wood development in the US is because of bark beetles.

Answer:

So the independent is what you keep the same. You must keep the experament controlled because if you have more than one variable there is the chance that you will not know what factor changed the experament.

Ex: If you are trying to find out the height of a plant based on what you add to the soil and you give it plant A water, plant B soda, and plant C milk, AND you stick plant A and B in the shade and stick plant C in the sun you will never know what affected the hight of the plant due to the different variables.

Controlled variable can show the accuracy of the result of the experiment, it prevent bias of the experiment.

Variables are the measurable factor present in an experiment which can be manipulated and controlled in research like person's eye color, its value can which change from brown to blue depend on different factors.

An independent variable is a characteristic variable which can not be affected by other factor, Age is an example of an independent variable.

A dependent variable depend on other variable and it can be changed by  independent variable like grade on an exam is a dependent variable mainly depend on Independent variables.

Control variable can be defined as the constant variable which remain constant show an effect on other variables and it is used to prevent bias in an experiment.

The height of the plant based on what you add to the soil and give it to plant A water, plant B soda, and plant C milk, and stick plant A and B in the shade and stick plant C in the sun  never know what affected the Hight of the plant due to the different variables.

The binomials for the length and width (4x - 5) and (3x + 3) respectively.

The length of the short side is 12, option C.

Factor the area of the rectangle as:

12x² - 8x - 15 = (4x - 5)(3x + 3)

The binomials (4x - 5) and (3x + 3) represent the length and width of the rectangle, but to determine which is which. Since the length is usually greater than the width, we can see that (4x - 5) represents the length and (3x + 3) represents the width.

To find the length of the short side when x = 4, we can substitute 4 for x in the expression for the width:

3x + 3 = 3(4) + 3 = 12

Therefore, the length of the short side when x = 4 is 12.

Answer:

DNA polymerase is an enzyme that works to transport DNA from the nucleus to the cytoplasm.

To perform a cross between a homozygous red and tall flower (RR TT) and a white heterozygous tall flower (rr Tt), we can use a Punnett square to determine the possible genotypes and phenotypes of the offspring.

First, we write the alleles of each parent along the top and left side of the square:T | RR Tt |

T | RT RT |

Then, we fill in the boxes with the possible combinations of alleles:T | RR RT |

T | RT TT |

From this Punnett square, we can see that all of the offspring will be tall (TT or Tt) because the tall allele (T) is dominant over the short allele (t). However, all of the offspring will be heterozygous for the tall allele (Tt) because the homozygous dominant genotype (TT) is not possible. Finally, all of the offspring will have red flowers because the red allele (R) is dominant over the white allele (r).

Therefore, the possible genotype and phenotype of the offspring will be TtRr and tall with red flowers.

Article states that "plants take up carbon dioxide from atmosphere and convert it into food."

1.This supports the law of conservation of matter, which states that matter cannot be created or destroyed, and can only be transformed from one form to another. In this case, carbon dioxide in atmosphere is transformed into organic matter in form of plant tissue.

2. According to the article, new research shows that plants are photosynthesizing 5% more in response to increased levels of CO2 in atmosphere.

3.The article states that 5% increase in photosynthetic rate translates to  additional 5 billion tons of carbon being removed from atmosphere each year.

4.Article suggests that increase in photosynthetic efficiency may be a result of plants having more CO2 available to them, which stimulates photosynthesis.

5.Laboratory procedure used to quantify photosynthetic efficiency involves measuring amount of chlorophyll fluorescence emitted by plant. This fluorescence provides a measure of amount of light energy absorbed by plant during photosynthesis.

6. Field procedure used to quantify photosynthetic efficiency involves measuring amount of carbon dioxide taken up by plant during photosynthesis. This is done by placing plant in sealed chamber and measuring change in carbon dioxide concentration over time.

7.The article suggests that potential "saturation" of carbon dioxide in the atmosphere could lead to a leveling off of increased photosynthetic rates observed in plants.

9.The potential "saturation" of carbon dioxide in atmosphere refers to point at which plants would no longer be able to increase photosynthetic rates in response to higher levels of atmospheric CO2. If ecological photosynthetic rates were to reach saturation, it would mean that plants would no longer be able to remove more carbon dioxide from atmosphere through photosynthesis.

Autotrophs are plants, algae, and other organisms that can make their own food.

These organisms are called autotrophs, which translates to "self-feeders." Autotrophs play a crucial role in ecosystems as primary producers, forming the foundation of food chains and providing sustenance for other organisms. Photosynthesis is a complex biochemical process that occurs in the chloroplasts of plant and algal cells.

It involves the conversion of light energy from the sun into chemical energy in the form of glucose. Autotrophs accomplish this by utilizing pigments, primarily chlorophyll, to absorb light energy. During photosynthesis, autotrophs take in carbon dioxide from the atmosphere and water from the environment. With the aid of sunlight, these raw materials are transformed into glucose and oxygen.

Glucose serves as an energy source for organisms, while oxygen is released back into the atmosphere as a byproduct. This ability to synthesize their own organic compounds from inorganic substances gives autotrophs a distinct advantage.

Autotrophs exist in various forms, including land plants, such as trees, grasses, and flowers, as well as aquatic plants like seaweeds and pond algae. Additionally, certain bacteria and protists are capable of photosynthesis, broadening the range of autotrophic organisms.
