Answer:
P. ramorum infects trunks, branches, twigs, leaves, and leaf petioles (the slender stems that support leaves). Experiments on tanoak trees revealed they could be infected without showing cankers or bleeding symptoms, making diagnosis difficult. When visible, trunk cankers are similar to those of the red oak group.Explanation:

Briefly describe the layers of the atmosphere:Troposphere-Exosphere-Stratosphere-Mesosphere-Thermosphere-
Answer:
Explanation:
-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles
- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.
-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.
-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.
-Exosfera. It is the last layer, the outerest until connected with the solar wind.
Why can some hazards be predicted and others can’t?
Answer:
Predicting the size, location, and timing of natural hazards is virtually impossible, but now, earth scientists are able to forecast hurricanes, floods, earthquakes, volcanic eruptions, wildfires, and landslides using fractals.

The measurement used for insulation is called the: H-factor R-factor X-factor L-factor
Answer:
R-factor.
Explanation:
Insulation can be defined as the process in which physical objects (materials) oppose the flow of current by providing a least resistance path or the opposition to the conduction of heat energy.
R-factor is an abbreviation for thermal resistance. The R-factor is the most commonly used measurement for providing all of the informations about the insulating properties of an insulator. Therefore, the measurement used for insulation is called the R-factor.
Most manufacturers specify the R-factor on the label of an insulating material.
Generally, the higher the R-factor of an insulating material the better it is for insulation.
Hence, the ability of a material to prevent the flow of heat or electricity (current) is largely dependent on its R-factor.
Question 4
By examining
scientists can test predictions for situations in which it is
impossible or unethical to use experiments.
O variables
O control groups
observations
O correlation
Answer:
correlation
Explanation:
By examining correlation, scientists can test predictions for situations in which it is impossible or unethical to use experiments.
Correlation determines if there is, and measures the strength of the relationship between two variables. Hypotheses are usually tested by experiments in science, but some situations make experiments impossible or unethical to be performed directly. In such cases, simulational experiments are performed and correlation is used to theoretically determine or predict the outcome of situations.

1. How does soil porosity affect water holding capacity?
Answer: Soil porosity refers to the space between soil particles, which consists of various amounts of water and air. Porosity depends on both soil texture and structure. ... Water can be held tighter in small pores than in large ones, so fine soils can hold more water than coarse soils.
Explanation:
Answer:
the soil porosity refers to the space between soil particles
1) List 10 ways that energy is used in your home or outside of your home.
2) Now, imagine yourself having surgery in a hospital and the power goes out. What could be done that the surgery could continue?
Answer:
There are many ways to save energy at home some are as following:-
1)Use Led Bulbs rather than Tubelight
2)Using Heater or Air Conditioner uses a lot of energy so we should reduce there usage
3)If possible, install a programmable thermostat to automatically adjust your home's temperature settings when you're away or sleeping.
4)Use a bucket of water rather than taking a shower
5)During Winter season use suns heat to heat up your body rather than using heater at day time
6)Save water by scraping dishes instead of rinsing them before loading in the dishwasher
7)Close the tap when not in use
8)While brushing tour teeth, use utensils to clean your mouth rather than using a tap
9)The water you use to mop the floor can we used to water the plant or even clean your car
10)Dont use dryer to dry your cloth rather put it in under sun

Explain the relationship between codon and gene.
Answer:
A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.

What is the energy source for producers, consumers, and decomposers?
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Find out two types of water purification and name and describe them here.
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.
The diagram below represents a plant cell and three different molecules
used by the cell. Molecule 1 is able to ENTER the cell using the process of *

Mrs. Jones has type B blood. Her mom has type A and her dad has type B. What must her mom's genotype be?
Answer:
I^Ai
Explanation:
because she can't have both dominant A's. if she had, jones were AB
If Mrs. Jones has type B blood and her mom has type A and her dad has type B, so iAi is the genotype of her mom.
What is genotype?It is the representation of genetic content of an organism, iAiA genotype shows type A blood group, it is the sum of gene that is transfer from parents to offsprings.
If cross between father having type B blood group and mother type A blood group having genotypes of iBiB and iAi.
Cross: iBiB X iAi
Gametes: iB, iA and i
Genotypes of the offsprings: iBIA, iBi, iBIA, iBi
Phenotypes: AB, B, AB and B.
The cross is attached in the image below.
If only mom's genotype is iAi, is crossed with iBiB, so the children have probability for having blood group B.
Therefore, iAi is the genotype of her mom, makes the possibility for Mrs. Jones to have type B blood.

In a DNA strand, you find that 20% of the bases are Adenine. What percentage of the DNA would be Cytosine?
Answer:
Yes
Explanation:Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.
