Three question that are missing from given question are as follows:
Identify the problem(s) at hand.
Determine the cause of the problem(s).
Recommend solutions to the problem(s).
Answer:
The nesting area of ocean turtles could be saved and secured with the assistance of commitment of neighborhood individuals , maintaining a strategic distance from of beach fires during nesting season. Leave the enough beach area for the turtles to hatch their egg and nesting.
There ought to be negligible lighting close to the settling regions as arched turtles are attracted to light and they may wind up moving towards the city as opposed to the water. Local people could protect the hatching eggs from other wild creatures and winged animals by tagging them and keeping a nearby eye.
Beach region should be cleanup as the debri are the significant reason forever danger to the turtles and all other marine creatures.
If a burning splint is placed in a container and burns more brightly in the presence of some gas already in the cylinder, that gas would probably be Oxygen.
Oxygen is the main component of air that we need to breathe. It is the most commonly available oxidizer. Besides combustion, it plays many roles in our life such as; the food we eat requires oxygen which helps in digestion and absorption of nutrients by the cells.
Answer:
D. Fossil record.
Explanation:
The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.
They are all part of the digestive system, they all break down food, they all have enzymes
Answer:
A. True
Explanation:
There are two sites where exchange of gases takes place, one is the exchange of gases between alveoli and blood and the second is exchange of gases between blood and tissue. In this question we are discussing about the about the diffusion of CO2 from blood to the alveoli for exhalation. CO2 must cross the diffusion membrane.
Diffusion membrane: The alveolar wall is thin and has rich network of capillaries. Due to this network, alveolar wall looks like a sheet of flowing blood and is called the diffusion membrane or alveolar-capillary membrane.This diffusion membrane is made up of three layers:
a. The thin squamous epithelium of alveoli
b. Endothelial lining of blood capillaries
c. a fused basement membrane between epithelium of alveoli and endothelium of capillaries.
All these three layers make the total thickness of about 0.2 mm.
