1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are soluble in it. Water is such a good solvent because the molecular structure of a water molecule is polar, having a negative charge at one end and a positive charge at the other end. Which model best represents a water molecule? A. B. C. D.
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

Which statement is true about Earth's outer core? A. It is believed to be made mostly from copper deposits. B. It is the outermost layer of the planet. C. It is composed of liquid metal. D. It is the thinnest layer of the planet.
Answer: c
Explanation: makes sense
The Earth's outer core is mainly composed of the liquid metals such as iron and nickel. Thus, the correct option is C.
What is the outer core of the Earth?The outer core begins approximately in the range of 2,889 km or 1,795 miles beneath the Earth's surface at the core-mantle boundary of the Earth and ends at 5,150 km or 3,200 miles beneath the Earth's surface at the inner core boundary of the Earth.
The outer core of the Earth is mostly composed of liquid iron and nickel. The Nickel and Iron alloy of the outer core is very hot, between 4,500° and 5,500° Celsius temperature. The outer core of the Earth is mostly made up of iron and nickel elements. This alloy is often written as NiFe because it is a combination of their chemical element symbols.
Therefore, the correct option is C.

Wolves prey heavily on beavers in a temperate forest ecosystem. The diet of beavers consists of the leaves, branches and bark from trees, as well as many types of aquatic vegetation. In this relationship, what is the role of the wolves? A producer B decomposer C primary consumer D secondary consumer
Answer:
In this relationship , the role of wolves is as Secondary Consumers .
Explanation:
A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.
All the green plants, for example.A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).
Fungi and bacteria that derive their nutrients from dead plant or animal matter are examples of decomposers.PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.
Insects, mice, and deer are common examples of this type of product.SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.
You can find secondary users, such as dogs , cats, moles, and birds, in temperate areas , for example. Foxes, owls, and snakes are other examples. Examples of secondary consumers that receive their energy from primary consumers by scavenging are wolves, crows, and hawks.In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .
Hence, the correct answer is OPTION D.

How does the cell membrane help maintain health in life
Answer:
The cell membrane controls the substances that enter and exit the cell
Explanation:
The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.
The membrane is a semi-permeable barrier that lets some substances in and out, but not others.
Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

Answer:
The surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable. How does the biomolecule that makes up this surface differ from other biomolecules? It is made up of polymers of amino acids. It is made up of long chains of fatty acids.
Explanation:
The biomolecules that make up this surface of leaves differ from other biomolecules by the fact that they are made up of long chains of fatty acids. Thus, the correct option is A.
What are Biomolecules?Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.
The long chains of fatty acids typically consist of a hydrophobic arrangement that prevents the movement of water from one part to the other. This specific property of forming a water barrier is only present in fatty acids.
Due to this, the surfaces of the leaves of many plants help to reduce water loss because they are not water-permeable, which means to prevent the migration of water.
Therefore, the correct option for this question is A.
