Answer:

B. Herbicides

Explanation:

Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.

Mowing, net barriers and inspections are mechanical controls.

Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.

The use of herbicides is a chemical control of plants that grow where they are not wanted.

Answer:

Example of Chemical Control of Non-native species.

B) Herbicides

Explanation:

In the given options, all of them are can be used to remove or control non-native species. but among them only Herbicides is the chemical solution to control non-native species.

Herbicides are chemicals that are used to kill unwanted plants, which can be taken as non-native species.

Some of the herbicides kill the unwanted plants while leaving the desired crops unharmed, some interfere with the growth of such species while some kill all the plant material with which they come in contact with

Why shouldn´t people be afraid to love themselves at all
Vlad1618 [11]

Answer:1. Real love makes us feel vulnerable. A new relationship is uncharted territory, and most of us have natural fears of the unknown. Letting ourselves fall in love means taking a real risk. We are placing a great amount of trust in another person, allowing them to affect us, which makes us feel exposed and vulnerable. Our core defenses are challenged. Any habits we’ve long had that allow us to feel self-focused or self-contained start to fall by the wayside. We tend to believe that the more we care, the more we can get hurt.

2. New love stirs up past hurts. When we enter into a relationship, we are rarely fully aware of how we’ve been impacted by our history. The ways we were hurt in previous relationships, starting from our childhood, have a strong influence on how we perceive the people we get close to as well as how we act in our romantic relationships. Old, negative dynamics may make us wary of opening ourselves up to someone new. We may steer away from intimacy, because it stirs up old feelings of hurt, loss, anger or rejection. As Dr. Pat Love said in an interview with PsychAlive, “when you long for something, like love, it becomes associated with pain,” the pain you felt at not having it in the past.

3. Love challenges an old identity. Many of us struggle with underlying feelings of being unlovable. We have trouble feeling our own value and believing anyone could really care for us. We all have a “critical inner voice,” which acts like a cruel coach inside our heads that tells us we are worthless or undeserving of happiness. This coach is shaped from painful childhood experiences and critical attitudes we were exposed to early in life as well as feelings our parents had about themselves.

While these attitudes can be hurtful, over time, they have become engrained in us. As adults, we may fail to see them as an enemy, instead accepting their destructive point of view as our own. These critical thoughts or “inner voices” are often harmful and unpleasant, but they’re also comfortable in their familiarity. When another person sees us differently from our voices, loving and appreciating us, we may actually start to feel uncomfortable and defensive, as it challenges these long-held points of identification.

4. With real joy comes real pain. Any time we fully experience true joy or feel the preciousness of life on an emotional level, we can expect to feel a great amount of sadness. Many of us shy away from the things that would make us happiest, because they also make us feel pain. The opposite is also true. We cannot selectively numb ourselves to sadness without numbing ourselves to joy. When it comes to falling in love, we may be hesitant to go “all in,” for fear of the sadness it would stir up in us.

Moishe was named by his grandparents, who had arrived in the United States a decade before he was born and still spoke only Yidd
Colt1911 [192]
This is an example of A. Assimilation. In this case Moishe is taking on a common name of the local community/culture in which his family has migrated into. By choosing a common name he will "blend in" with the other children. To assimilate, means to replicate or copy.

Unionization, cronyism and maturation are not appropriate to this situation.

Based on the given information, determine which company has a lower minimum and find the minimum value. g(x) at (10, 855) f(x) a
Gekata [30.6K]

The minimum production cost of company 2 is greater than the minimum production cost of company 1. We arrived at this value by comparing the production cost of both companies.

<h3>What is meant by minimum production cost?</h3>

The overall cost incurred by a company to manufacture a product or provide services is known as the cost of production.

The objective of every company is to keep this cost at minimum, hence the minimum production cost.

<h3>How do find minimum Production Cost?</h3>

Recall that the production function is given as:

f(x) = 0.25x² - 8x + 600

Inserting the values given by the schedule we have

  1. f(6) = 0.25(6²) - 8(6) + 600 = 561
  2. f(8) = 0.25(8²) - 8(8) + 600 = 552
  3. f(10) = 0.25(10²) - 8(10) + 600 = 545
  4. f(12) = 0.25(12²) - 8(12) + 600 = 540
  5. f(14) = 0.25(14²) - 8(14) + 600 = 537

For company 2, we are given the various production costs as;

x   - g(x)

6  - 862.2

8  - 856.8

10 -  855

12 -  856.8

14 - 862.2

Juxtaposing the above, we can infer that the minimum production cost of company 2 is greater than the minimum production cost of company 1.

Choose the best Spanish word to complete the sentence. La cuñada de Pedro está___________a la abuela. visitando visitante visita
AlladinOne [14]

The purpose of the question is to properly identify the tense of the verb being used. For this case, we use context clues to infer that the verb is being used in the present tense and will answer accordingly.

From the sentence given, we can use the word "está" as context to determine the tense of the verb. "Está" is used in the present tense. The other ways to use this word are:

  • "Estuvo", signals a past tense of a verb will follow.
  • "Estara", signals that a future tense of a verb will follow.

The fact that the previous word is being used in the present tense allows us to infer that the verb will be used in the present tense as well. Therefore, we choose the present tense of the verb "visitar" which corresponds to "visitando" and fill in the blank with this word.

Assuming ideal solution behavior, how many liters of hcl gas, measured at 30. 0 °c and 745 torr, are required to prepare 1. 25 l
Nostrana [21]

The volume of HCl gas required to prepare the solution is 101.54 L

<h3>How to determine the mole of HCl </h3>
  • Volume of solution = 1.25 L
  • Molarity = 3.20 M
  • Mole of HCl =?

Mole = Molarity x Volume

Mole of HCl = 3.2 × 1.25

Mole of HCl = 4 moles

<h3>How to determine the volume of HCl </h3>
  • Number of mole (n) = 4 moles
  • Temperature (T) = 30 °C = 30 + 273 = 303 K
  • Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Volume =?

Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:

PV = nRT

Divide both side by P

V = nRT / P

V = (4 × 0.0821 × 303) / 0.98

V = 101.54 L
