Answer:
Red blood cells are adapted to their function by:
1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.
2) They are small and flexible so that they can fit through narrow blood vessels.
3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.
Hope this helps! :D
In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation. ... Products need energy and water, as well as land for shipping, marketing and use.
Sorry if I didn’t help
Anyways have a nice day / night! :)
Answer: Options A, B, D and E.
A. Process for initiating.
B. standard reporting format.
D. process for synthesizing the body of evidence.
E. process for finding and assessing individual studies.
Explanation:
Systematic review is a scientific process which combines findings from research using random sampling of works from different source of a particular subject and integrating them into a powerful and clinically useful report to guide practice. It is a form of paradigm that guides and aids further research in a particular field.
However, there are components to be considered in other to create a perfect resolution. Initiation of the process begins with gathering of research from different source.
Then, individual research work is also accessed to derive facts and putting up a standard report to explain the total discovery.
A tropism.
A plant movement to a light stimulus is a phototropism.
A plant movement to water stimuli is a hydrotropism.
etc. etc. :)
<u>Answer:</u>
Greenhouse gas refers to any gaseous compound in the atmosphere that can absorb infrared radiation, thereby trapping heat and keeping it in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
<u>Examples why greenhouse gases in the atmosphere:</u>
- farming cattle releases methane
- farming rice in paddy fields releases methane
- burning fossil fuels in vehicles and power stations releases carbon dioxide
- deforestation releases carbon dioxide and reduces the absorption of carbon dioxide through photosynthesis
