1.The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably.

2. Potentially renewable resources include wood and biofuel. Nondepletable resources include wind, solar, hydroelectric, and geothermal energy.

3. They often serve important ecological functions, provide coastal protection, and are critical resources for food, energy, tourism and economic development. In many parts of the world, such marine and coastal systems are under stress or are threatened from a variety of sources, both human and natural.

The movement of water across the plasma membrane can be described by all of the following except carrier-mediated facilitated diffusion (d)

Water is able to across the plasma membrane through some mechanisms. Water pass through membranes via two pathways: simple diffusion through the lipid bilayer, or water-selective facilitated diffusion. Both of them depict the passive transport. In other word, water crosses the membrane through passive transport only. 

Since, the carrier-mediated transport can be active transport, this type of transport is excluded as the way for water crossing the membrane.

The maximal population of some bacterial species at the end of the log phase can reach a density of 10 to 30 billion cells per milliliter under ideal circumstances.

Since the very beginning of life on Earth, bacteria have existed.

There is strong evidence that bacteria have existed since the early Precambrian Period, or roughly 3.5 billion years ago, as evidenced by the discovery of fossilized bacteria in rocks from the Devonian Period (419.2 million to 358.9 million years ago).

At least since the Paleoproterozoic period, which lasted for around 1.8 billion years, when oxygen was produced by cyanobacteria and entered the atmosphere, bacteria have been present in large numbers on Earth.

As a result, bacteria have had plenty of time to evolve into a variety of offspring forms and adapt to their environs.

Treisman's attenuation model was proposed as an alternative to Broadbent's model of selective attention. Broadbent's model proposed that sensory information was filtered based on its physical characteristics before being processed for higher-level attention. However, Treisman's experiments showed that some unattended information was still processed to a certain extent, indicating that there must be another mechanism involved in selective attention.

Treisman proposed that instead of a strict filter, attention worked more like a volume control, where incoming sensory information was attenuated based on its perceived importance. In her attenuation model, the initial sensory analysis is still similar to Broadbent's model, but instead of being completely filtered out, unattended information is weakened or attenuated. This weakened information can still reach higher-level processing but at a lower intensity than attended information.To explain these findings, Treisman modified Broadbent's model by adding the concept of attenuation, where the selection process is more flexible and depends on the perceived relevance of the stimuli. This modification allowed for the processing of some unattended information that had previously been filtered out by Broadbent's model. Treisman's attenuation model has become a widely accepted theory of selective attention, offering a more nuanced understanding of how we selectively attend to the world around us.
Hi! Treisman's attenuation model was proposed as an alternative to Broadbent's filter model of selective attention. The reason for proposing this theory was to address some limitations in Broadbent's model, which couldn't explain certain phenomena like the cocktail party effect or the ability to notice meaningful information from unattended stimuli.
Treisman's attenuation model modified Broadbent's model by introducing the concept of an attenuator instead of a strict filter. The attenuator allows for the processing of unattended stimuli at a lower level, rather than completely blocking them. This enables the brain to recognize important or relevant information from unattended channels, which Broadbent's model couldn't explain.

The two natures of insular biotas refer to their isolation and unique ecological characteristics. Insular biotas are typically isolated from mainland ecosystems and have evolved in distinct ways due to their insularity.

Two natures of insular biotas are:

1. Isolation: Insular biotas, being located on islands or isolated areas, experience limited interaction with other ecosystems. This results in unique species compositions and adaptations due to the absence of certain external influences.

2. Endemism: Insular biotas often have high levels of endemism, meaning many species found in these ecosystems are unique to that specific location. This is a result of the isolation, which allows species to evolve independently from their mainland counterparts.

This isolation has led to the development of unique species and communities, as well as increased vulnerability to threats such as invasive species and habitat loss.

The insular nature of biotas also means they are often more sensitive to environmental changes, making conservation efforts crucial for their survival.

Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. These macromolecules (polymers) are built from different combinations of smaller organic molecules (monomers). What specific types of biological macromolecules do living things require? How are these molecules formed? What functions do they serve? In this chapter, these questions will be explored

The major molecule that is said to be the backbone of all other large molecules in living cells would be the monomers.

Large macromolecules are made from the combination of smaller macromolecules. While the former are referred to as polymers, the latter are known as monomer units.

For example, proteins is a macromolecule that is formed from amino acids. units linked together by peptide bonds. Starch found in living cells are polymers of monosaccharides such as glucose and fructose. Monomers of lipids are fatty acids and glycerol while nucleic acids are polymers of nucleotides.

Polymers are formed from monomers by addition or condensation polymerization reactions.

Because the parallax values for nearby stars are just a fraction less than one arcsecond, astronomers use arcseconds.

Angles may also be quoted in mas, which stands for milli-arcseconds: One mas equals one thousandth of an arcsecond. A parsec is defined as the distance between two stars with heliocentric parallax half-angles of one arcsecond.

The parallax angle is the angle measured from a nearby star between the Earth at one time of year and the Earth six months later. Astronomers use this angle to calculate the distance between Earth and a star. d = 1/p, where d is the parsec distance from the star (1 pc = 3.26 light-years) and p is the parallax angle in arc seconds.
