Explain why weak bonds are important to living organisms
Answer:
¨ For instance, strong covalent bonds hold together the chemical building blocks that make up a strand of DNA. However, weaker hydrogen bonds hold together the two strands of the DNA double helix. These weak bonds keep the DNA stable, but also allow it to be opened up for copying and use by the cell.¨

4. What role do marine laboratories play in the field of marine science?
Answer:
Explanation:
Marine laboratories allow marine biologists to keep organisms alive and to work over long periods of time. They also may have state-of-the-art equipment for conducting scientific research or they may be simple field stations that provide a base for scientists who work in remote areas.
Marine laboratories allow to keep marine organism for a longer period and allow to do research on them by marine biologists.
What is marine biology ?The field of study of marine organisms, their behaviors and interactions with the surrounding called as marine biology.
The marine biologist understand the marine species by studying the biological oceanography and their associated chemical, physical, and geological components.

Mathematical models can be useful for researching ecosystems that are otherwise difficult to study, such as_____.
Answer:
The correct answer is "a large-scale natural system such the Great Lakes".
Explanation:
Mathematical models are used in scientific investigations to study complex systems. This applies to the study of ecosystem dynamics of large-scale natural systems such as the Great Lakes. The Great Lakes comprise five lakes that in conjunction are 244,106 km2 long, with a complex ecosystem that includes invasive species, climate change, pollution, among other factors. It will be very complicated to study the ecosystem of such a large habitat without using mathematical models.

African Savannah is the largest biome situated in the Kalahari region of South Africa. The animals and plants found in African Savannah are zebra, giraffe, and several mammals.
Describe the habitat of the giraffe?The giraffes have a special niche in the ecosystem of the African savannah.
Giraffes are the most elevated organisms, which allow them to feed directly on the foliage and leaves present at a great height. The other animals and small organisms are unable to reach such height.
The Giraffes have long tongues, which make them pull leaves from the branches of the trees.
Thus, giraffes also show a mutualistic relationship with ticks and have a special ecological niche in the savanna.

Finally, near the equator ( 0-30° North and South) the NPP is relatively the same. Why is that?
Answer:
Once on the ground, the air returns to the equator. This convection cell is called the Hadley Cell and is found between 0 degrees and 30 degrees N. There are two more convection cells in the Northern Hemisphere.The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude.
Explanation:
Hi! I am having trouble labelling this Plant cell, so could you please help me label it?

Question 8
Which of the following best describes the structures of carbohydrates?
A
They only occur as disaccharides.
B
They occur as monomers, chains of monomers, and branched structures.
с
They only occur as long and branched structures.
D
They occur as chains of monomers that hydrogen bond with complementary chains of monomers.
Answer:
D
Explanation:
The better description of the structures of carbohydrates is Option B They occur as monomers, chains of monomers, and branched structures.
Carbohydrates can be divided into monosaccharides (simple monomers), disaccharides (composed of two monosaccharides), and polysaccharides (long chains of monosaccharides) depending on the number of monomers that form the molecule.Carbohydrates are simple or complex structures composed of carbon (C), hydrogen (H) and oxygen (O).Simple carbohydrates include both monosaccharides and disaccharides such as glucose, fructose, and lactose.Complex carbohydrates are polysaccharides that may be branched or not branched (e.g., starch, glycogen, amylopectin, cellulose, and chitin).In conclusion, carbohydrates can be monomers, chains of monomers, and branched structures (Option B)
