The ecological definition of sustainable harvesting is harvesting that allows population numbers to be maintained or to increase over time. A lagging economy and a lack of alternative construction materials make mangrove harvesting inevitable, and for local people, an economic necessity.
2. Which specific cytoskeletal element is most susceptible to mitotic inhibitors?
Answer:
microtubules
Explanation:
Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.
What is Microtubules?The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.
They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.
Microtubules, which typically consist of 13 linear protofilaments arranged around a hollow core, are created when tubulin dimers polymerize to generate them. The head-to-tail arrays of tubulin dimers that make up the protofilaments are organized in parallel.
Therefore, Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.
Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.
The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.

When muscle cells run out of____________, they resort to lactic acid fermentation for a supply of energy. A. Carbon Dioxide B. Oxygen
Answer:
B oxygen
Explanation:
When your body runs out of oxygen, or your other systems can't deliver oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead.
Lactic acid fermentation is the energy source used by muscle cells when their supply of oxygen runs low.
What is muscle cell?A muscle cell is sometimes known as a myocyte because smooth muscle cells and cardiac muscle cells are both very small cells. The long, threadlike cells of skeletal muscle with many nuclei are known as muscle fibers. Muscle cells are derived from myoblasts, which are embryonic progenitor cells.The cytoplasm and cell membrane of a muscle cell are known respectively as sarcoplasm and sarcolemma. The sarcoplasm contains myoglobin, which is a site for storing oxygen, and glycogen in the form of granules in the cytosol, which is an energy source.When your body runs out of oxygen or when your other systems are unable to transfer oxygen to your muscles quickly enough, your muscles convert the available glucose into lactic acid instead of oxygen.To learn more about muscle cell refer to:

What is another way nitrogen is added back into the atmosphere BESIDES animal waste, but is too unreliable to count on?
Answer:
Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.

C. 0.9420/s north
d. 56.67 m/s north
e. 1.34 m/s north
f. 0.56 m/s north
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=0.9420m/s[/tex]
Answer:
0.9420m/s north
Explanation:
Given,
Displacement (Total) = 6800 metres(m)
Time = 2 hours
We need to convert hours to seconds.
2 hours = 7200 seconds
We know,
[tex]\sf\longmapsto \: Average \: velocity = \frac{Total \: Displacement}{Total \: time} [/tex]
Let's start solving!
[tex]\sf\longmapsto \: Average \: velocity = \frac{6800 \: metres}{7200 \: seconds} [/tex]
[tex]\sf\longmapsto \: average \: velocity = 0.9420\: m/s[/tex]
how the function of the basal cells depends on the relationship among its parts?(respiratory system )
Answer:
Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

Explanation:
Looking for input and other opinions with the following statement. 'environmental factors influence the rate of natural selection." I am to make a claim on whether I agree or not and why. I agree with the statement. This is because all literature states that with natural selection it's basically the best man/woman wins. I feel that with that statement it directly refers to the environment if food is scarce then the best hunter the best runner is going to get the food first if the weather is changing and it's time to move on or hibernate then the one with the best intuitions will move on or assume hibernation and wont be left to the cold as well as if they are the prey to something else as everything is the best one to keep alert and observant to their surrounding would be the one to survive longer. Although I think that the only downfall to that would be if something happened and the appearance was to change and made them less desirable in that manner but then would in turn help themselves to camouflage to hide better.
I agree completely.
Environmental factors control evolution through surivial of the fittest, or natural selection. This is not nearly as much the case with humans as wild animals, or early on humans, but it does still come into play. For example, lactose intolerance was erradicated in areas where milk was a primary source of nutrients during a famine. The famine was environmental, causing natural selection to elimate lactose intolerant people in the area.
A more basic example is fur color of certain animals. They were selected by their environment to survive and pass on their genetics, causing the species to evolve.
