Answer:

if a mutation, for example, an insertion or a deletion of the nucleotide, occurs, this could result in the alteration of the reading frame. It completely changes the amino acid sequence. Such mutations are known as frameshift mutation (also called reading frame mutation, reading frame shift, or framing error).

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

An organ system consists of a group of organs that performs specific functions necessary for the survival of an organism. Humans
scoundrel [369]

The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.  

• Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are "finger-like" projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.  

• The brain is the control center of the body. One of these furrows, the medial longitudinal fissure, divides the brain into left and right hemispheres. Covering the brain is a protective layer of connective tissue known as the meninges.

• The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body.

Romashka [77]

Explanation:

In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.
