Bacteria perform the following ecological roles. Which role typically does not involve symbiosis?

Answer: Decomposer

Explanation:

Bacteria feed on the dead and decaying organism, in which they feed on them and obtain energy from them.

It is not a mutual relation because the host cell on which they feed is not alive. They eat the organic matter that is present in environment.

The bacteria and fungi clean the environment in this way. The dead plants and animals are decomposed in the environment and the nutrients get back  into the soil.

hence, the correct answer is option B

Where could the instructions be held to create a protein?
FromTheMoon [43]

Answer:

The correct answer is - in DNA molecules.

Explanation:

The instructions or the information for the creation of the protein is held in the DNA molecule inside the nucleus in eukaryotic organisms while present in the cytoplasm in prokaryotes.

The DNA molecule has coded all the information for the particular protein by the two processes transcription and translation. Transcription is the first step which makes a copy of the DNA is complementary in the form of mRNA, The second step involves the decoding mRNA into an amino acid chain with the help of ribosomes.

Most of the fatty acids in cells contain an even number of carbons with _____ carbon atoms per molecule.
Rom4ik [11]

Most of the fatty acids in cells contain an even number of carbons with 16 to 18 carbon atoms per molecule.

<h3>What are fatty acids?</h3>

Fatty acids are biomolecules which consist of a long non-polar hydrocarbon chain and a polar carboxylic acid head.

Fatty acid are found combined with glycerol molecules to form fats found in animals.

The oxidation of fatty acids produces large amount of energy for the body.

In conclusion. fatty acids are lipid molecules found in living organism that serve as energy stores.

Where can you observe environmental changes that are forcing adaptation?
Helen [10]

Answer:

Description

Since its inception, life on earth has had to adapt to changing environmental conditions - this represents a driving force of evolution.

This module examines how organisms detect and respond to changes in their environment, and reviews the different behavioural, physiological and molecular mechanisms underpinning environmental (stress) adaptation.

Understanding these organism-environment interactions forms the very foundations of ecology. Examples are provided from a range of organisms, but a specific focus is given to terrestrial invertebrates (insects) and plants.

The term “environment” covers a broad spectrum of spatial scales, from changes occurring at the cellular level, to large scale geographic differences between major climatic zones (polar, temperate and tropical).

The process of “change”, and adaptation to these changes, will in turn be discussed across a broad spectrum of timescales. These include:

The requirement for rapid adaptation to potentially dramatic shifts in environmental conditions, e.g. when a parasite first enters its host

Longer-term changes and adaptations across seasonal timescales, e.g. hibernation/insect diapause

Adaptation on an evolutionary timescale, e.g. the ‘Red Queen’ hypothesis, across scenarios of past environmental changes, and extending out to current predictive climate change models

The main aims of this module are to provide students with information, guidance, and access to resources, that will allow them to:

Gain an in depth understanding of how organisms respond and adapt to changes in their environment.

Recognize that the term “environment” covers a continuum of spatial scales from molecular environments within cells, to broad-scale geographic environments and climatic zones.

Appreciate that adaptation to environmental change for an individual organism is transient and occurs across a temporal spectrum of seconds to seasons. For species, adaptation is long-term, but not fixed/permanent, and occurs across a timescale of generations.

Interpret the potential impact of climate change on species, communities and ecosystems. Specifically with respect to how the rate of environmental change may limit effective adaptation, and so result in changes in species distribution and abundance patterns

Become effective independent learners, capable of analysing and interpreting the scientific literature to help formulate and express their own ideas
