Explain the difference: a myelinated axon conducts impulses faster than non-myelinated axon of the same diameter
Answer:
A myelinated axon conducts impulses faster than a non-myelinated axon. ... Therefore, in myelinated neurones, the nerve impulse is said to jump from node - to - node, a impulse pathway known as Saltatory Conduction. This means that the action potential does not have to travel along the whole length of the myelinated axon

in order to increase chances of survival in a changing environment, it is important for a species to have
Answer:
One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.

What are the benefits of flattened tails?The benefits of flattened tails are that or the difference in the tail shape is because Flattened tails are better for swimming than rounded tails. This is due to the difference in habitats of the marine and inland iguanas.
By natural selection, the nature of the species gradually changes to became adapted to the niche.This is due to natural selection.The marine iguanas of the Galapagos Islands feed on seaweed and algae. Marine iguanas have flattened tails while other species of iguanas that live inland on the Galapagos and on the South American mainland have rounded tails.

4. Diagrams, tables and graphs are used by scientists mainly to
predict the independent variable
test a hypothesis
design a research plan for the experiment
organize data
Answer:
word to my dead When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.

In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation, Constant UV exposure
resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow
leaves evolved into needles.
Relate the development of plant needles to the occurrence of mutations,
A)
Plant needles adaptations for survival that some plants developed due to
high temperatures on Earth
B)
Plant needles are the result of leaf cell mutations that made some leaves
thick and waxy, while other leaves did not change,
Plant needles are the result of neutral mutations to leaf tissue that would
neither help nor harm the plants living in such a harsh environment.
D)
Plant needles were a beneficial mutation that increased survival of certain
plants that reproduced and passed the mutated gene to offspring,

Describe how an ecosystem with high biodiversity might look compared to an ecosystem with low biodiversity.
Answer:
High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity.

which feature of stem cells enable them to replace cells in tissues such as skin?
The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.
What is a stem cell ?A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.
They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.
Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.
Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.
Adult stem cells generate new cells as an organism matures and replace damaged ones.
Induced stem cells are stem cells created in the laboratory by scientists.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?
Answer:
Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.
Explanation:
Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.
For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.
Answer:
Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

Explanation:
Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained
HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases.
GREENHOUSE GASES
Water vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).
Describe the size of insolation when it strikes the Earth.
What would happen if there were no greenhouse gases to trap heat?
