Explanation:

Answer:

f(34) = 52

Explanation:

f(x) = 2x-17; x=34

1. Plug the number 34 in all the x's you can find in the equation.

f(34) = 2(34)-17

2. Solve the parentheses.

f(34) = 68-17

3. Subtract.

f(34) = 52

What caused the tree bark to become darker?

What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?

The dark-colored peppered moth had a higher rate of survival than the light-colored moths.

What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.

What are Consumers?

Consumers are the group of organisms which cannot synthesize their own food and hence depends upon some other organism for their nutritional requirements.

Consumers are classified further on the basis of their nutritional requirements such as herbivores, carnivores, omnivores, etc. Bacteria and fungi are the examples of decomposers which feed upon dead and decay matter for nutrition.

Brown eye color is a dominant trait and blue eye color is a recessive trait
What typically happens when someone inherits one allele for brown eyes and one for blue eyes?
O The person has brown eyes, and brown eye color remains a dominant trait
O The person has blue eyes, but brown eye color remains a dominant tralt
O The person has brown eyes, but blue eye color becomes a dominant trait
O The person has blue eyes, and blue eye color becomes a dominant trait

Answers

Answer:

The answer is the first choice, the person has brown eyes , and the color remains the dominant trait.

Explanation:

When a person inherits a recessive trait and a dominant trait, their (in this case) eye color will always be brown. The only time a recessive trait will be inherited (having blue eyes) occurs when the offspring inherits two recessive traits.

A. The person has brown eyes, and brown eye color remains a dominant trait this typically happens when someone inherits one allele for brown eyes and one for blue eyes.

What's an allele simple definition?

An allele is one of two or more variations of DNA collection (an unmarried base or a phase of bases) at a given genomic area. A person inherits two alleles, one from every parent, for any given genomic vicinity where such a version exists.

What are alleles and examples?

A dominant allele will override the tendencies of a recessive allele in a heterozygous pairing. In a few trends, however, alleles can be codominant—i.e., neither acts as dominant or recessive. An instance is the human ABO blood group machine; humans with type AB blood have one allele for A and one for B.

4. guard cell

5. leaf epidermis

6. stoma

7. root hair

8. ground tissue (xylem vessel)

Explanation:

functions of :

stomata aid in losing of water during transpiration

guard cells regulate the opening and closing of the stomata .this happens when the guard cells have a hypertonic environment they absorb water from the neighboring cells hence they expand and the stomata open .during the night the sugar levels in the guard cells have dropped hence they lose water to the neighbouring cells hence they shrink become flaccid and the stomata close.

xylem transports water to various parts of the plant

cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through

root hairs are thin ,long and flexible.they are thin to reduce distance covered by diffusing water,they are long to allow their ability to tap water from underground,they are flexible to increase their ability to reach water sources .

True Goal-Setting, Expectancy, Reinforcement, and Equity Theory Goal-Setting, Expectancy, Reinforcement, and Equity Theories all serve Theory Y managers in understanding how employees can be motivated at work. Employees seek interesting and challenging work in a fair work environment that allows for autonomy. There should be a system to engage everyone in the organization in goal setting and implementation as well as an expectation that effort expended will result in a positive outcome and be balanced from one employee to another (given the same work). Managers can also find success in fairness and a reward system that all employees value.Goal-setting theory is based on the premise that employees are motivated when they are clear about the goals they are working toward. More importantly, they are more likely to engage to attain these goals if they collaborate with management in planning. Management by Objectives (MBO) is the process of discussion, review, and evaluation of goals between a manager and employee. Expectancy theory is based on the premise that the amount of effort employees exert on a specific task depends on their expectations of the outcome. Reinforcement theory states that individuals act to receive rewards and avoid punishment. A manager may attempt to surface good behaviors through rewards and extinguish poor behaviors through punishment. Equity theory zeros in on how employees' perceptions of fairness affect their willingness to perform. Roll over each employee name to read a scenario.
