The answer is <span>B. A smaller cell has more surface area than volume.

</span>This is simple mathematics. Let's imagine that cell is spherical.
Now, we have two spheres: one big (with radius r = 5 cm) and one small (with radius r = 2 cm).
The formula for the surface area of the sphere (A) is A = 4 π r².
The formula for the volume of the square is 4/3 π r³.

Now, let's compare two spheres:

Small sphere:                                                  Big sphere:
r = 2 cm                                                            r = 5 cm
A = 4 π 2² = 50.3 cm²                                      A = 4 π 5² = 314.2 cm²<span>
V = 4/3 </span>π 2³ = 33.5 cm³                                   V = 4/3 π 5 ³ = <span>523.6 cm³ 

According to the calculation, the smaller sphere will have more surface area than volume. This can be extrapolated to all shapes, not only spheres, so the </span><span>smaller cell has more surface area than volume.</span>

Svetlanka [38]
<h2>Neural crest </h2>

Explanation:

The neural crest likely forms: neurons and glia of the peripheral nervous system

  • The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
  • In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
  • The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
  • Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
  • Glia are also essential to nervous system function, but they work mostly by supporting the neurons

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

which of the following levels of protein organization shows the complete 3D arrangement of the polypeptide chain
kherson [118]

Proteins are the macromolecules made of hundreds of amino acids. Proteins are most varied class of biological molecules and show the greatest variety of structures. Many have detailed three-dimensional folding patterns that result in a compact form, but others do not fold up at all and they are in random conformations. The function of proteins depends on their structure.

The secondary structure of protein fold together to form the 3D arrangement of a polypeptide chain that results into Tertiary structure which is a functional protein.
