1156 g/L
= ________ kg/mL

Answers

The Answer is 0.001156.

To convert g/L to kg/mL, we need to divide the value of g/L by 1000. Therefore:
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.

Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.

Which technique is likely to have less of an impact on the environment?

Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.

What is Chemical Weathering ?

Chemical Weathering can be described as the type of weathering that do take place due to the breaking down of the rock particles into smaller pieces which is usually as a result of chemical process.

It should be noted that when the process is taking place it scould be due to the  Extreme heat and pressure  which can affect the composition of the particles and as  a result of this there could be formation of products from the break down.

These are both examples of chemical weathering because the composition of these things changed. When shale is worn into small pieces, it is still shale, and rocks breaking into pieces as they tumble down a mountain are both examples of physical weathering because the weathering is not changing the composition of the rock.

Explanation:

edge 2021

Cuticles are protective lining in the epidermal layer of plants. Cuticles helps to reduce water loss and protect the plants from environmental stresses.

What is cuticles?

Cuticle is an organism's external layer or area that makes touch with the environment. The epidermis secretes the dead, noncellular cuticle in many invertebrate species. In humans, the cuticle is the epidermis, and this layer may include colours and chitin, similar to arthropods.

The cuticle is a protective coating that protects the epidermal cells of leaves and other organs while preventing water loss in some higher plants.

It is made up of cutin, a waxy, water-repellent compound related to suberin that is present in the corky tissue's cell walls. Hence, option c is correct.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection

Which type of selection is shown in the graph above? A. Disruptive selectionB. Stabilizing selectionC.

Answers

The anwser is A Disruptive selection

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.

Answers

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

No it would not conduct electricity as it is a insulator

What is an electromagnetic wave? Use the model to describe the characteristics of these waves.

Answers

Electromagnetic waves are the type of waves that do not need a medium to travel in. For example, the sun's rays travel in space toward earth without any medium

Electromagnetic radiation contains waves of the electromagnetic field, which propagate through space and carry radiant energy. The radiations coming from the sun are electromagnetic waves.

What are electromagnetic radiations?

Electromagnetic radiation possesses waves of the electromagnetic field, which travel via space and carry radiant energy. These waves include microwaves, radiowaves, infrared rays, visible light, UV rays, X- rays, and gamma rays.

Electromagnetic waves oscillate with the electric field and magnetic fields. Electromagnetic waves exhibit periodic changes in the electric field or magnetic field.

Depending on the periodic change in the waves that take place and the power produced in the waves, different wavelengths or frequencies of the electromagnetic spectrum are produced.

The effects of this radiation on chemical compounds and biological organisms are related to the power of the radiation and its frequency.  

In order of increasing frequency and decreasing wavelength, electromagnetic waves are organized in the electromagnetic spectrum.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL

Answers

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

the correct answer is A 4.8 mL
