A salamander relies on hydrogen bonding to stick to various surfaces. Therefore, a salamander would have the greatest difficulty clinging to a______.A) Surface of hydrocarbonsB) Surface of mostly carbon-nitrogen bondsC) Slightly damp surfaceD) Surface of mostly carbon-oxygen bonds



Answer is A, surface of hydrocarbons.


The difficulty of salamander in attaching itself to the hydrocarbon surfaces is because the type of bond existing between hydrocarbon surfaces is covalent bond , and this is different to the surfaces which the salamander can cling to.

A covalent bond involves the sharing of electrons, while the hydrogen bond is the bond existing between hydrogen and larger molecule such as nitrogen or oxygen.

Salamanders are amphibians which have lizard like appearance and have short limbs. They relies on hydrogen bonding which helps them to stick to various surfaces.

A salamander would have difficulty in clinging to a surface of hydrocarbon.

They excrete toxic on their skins and are considered as poisonous. They can climb to walls and mountainous areas.

What determines the type of soil that is created when it is formed? A) The type of rock and minerals in the parent material

B) The types of organisms living in the soil

C) The altitude of the location of soil formation

D) The amount of time it takes to create the soil


The type of rock and minerals in the parent material determine the type of soil created. So the correct option is A.

What is the process of soil formation?

The soil is a very essential one of our natural resources. Soil is important for the growth of vegetation that we depend on for food. It provides the plants with stability and nutrition. Soil is also a habitat for many microorganisms. It is also important for earthworms, rats, and a lot of other subterranean species that are present on earth.

Parent material is the material from which soil is formed. The source of all soil minerals is the rocks. The parent material is weathered chemically or physically. It is then transported and then deposited for the formation of the layers of soil. The parent material is usually the bedrock. Soil can also get transported because of natural factors like wind and water.

Pedogenesis is the name of the process for the formation of soil. It is first initiated by the weathering of rocks. The variations are developed according to the weather conditions.

Therefore, the correct option is A.

The factors that affect soil formation are climate, rock type, slope, time, and biological activity. Differences in these factors will produce different types of soil. Soil type determines what can grow in a region. Humus, the decayed remains of living organisms, is essential for soils to be fertile.

Describe how information is transmitted from light receptors in the retina to the brain PLEASE HELP ASAP



Explained below


The wall of an eyeball has three layered-

  1. Sclera
  2. Choroid
  3. Retina

The space in the center of an eyeball is filled with jelly like material called vitreous humor, which allows light to pass through retina.

Innermost layer of eyeball (retina) is a soft, light sensitive layer of nervous system tissue. Signals from retina to brain carried out by optic nerve, which convert them as visual image.

Which statement BEST describes the Milky Way Galaxy? A) a spherical group of stars B) a spiral shaped cluster of stars C) an elliptical shaped cluster of stars D) a small group of stars with no real shape



Option B, a spherical group of stars


Milky way galaxy is also known as spiral way galaxy. It contains a bar structure at its center just like all other spiral galaxies. Also, it is a flat dic like structure which consists of thick center base with its arms extending out and coiling like a pine wheel.

These galaxies rotate very slowly at a rate of one rotation per 250 million years.

hence, option B is correct

B. A spiral shaped cluster of stars

Two stars, star 1 and star 2 are at almost equal distances from earth Star 1- 3.61 mass of star
Star 2- 3.59 mass of star

Which stamens is correct
A-Earth exerts almost equal gravitational force on both stars
B-earth exerts more gravitational force on star 1
C-star 1 attracts star2 with greater gravitational force than star 1
D-star 2 attracts star 1 with a greater gravitational force than star 1 attracts star 2



Option B and C


The mass of star 1 is greater than star 2  and hence the gravitational force exerted by star 1 on star 2 is greater as compared to the gravitational force exerted by star 2 on star 1

As per the standard equation - gravitational force between two objects is equal to

This equation clearly states that the gravitational force exerted between any two objects is governed by the masses of these objects.

Thus, earth (with constant weight ) exerts more force on star1.

A) is the answer.

B) looks fine, because M1 > M2, but we don;t know the actual distance with precision. Only approximately.

C and D) no sense, gravitational force of 1 upon 2 is the *same* as 2 upon 1 For instance: apple and Moon.
