What is difference between Microtubules and Microflaments?
Microfilaments
Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.
Microtubules
Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.

It is primarily made of dead, keratinized cells.Using complete sentences, compare and contrast the terms living and biotic. In your response, illustrate using examples and appropriate compare-and-contrast vocabulary
Both living things and biotic factors can be alive.
Unlike living things, biotic things may not be alive; they may have once lived or came from something living.
I included an example of something both living and biotic, such as flowers.
I included an example of something biotic, but not living, such as paper.
I used compare-and-contrast vocabulary.
Explanation:
As you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.
What is biotic?Biotic may be defined as something that is closely related to living organisms or something that is directly derived through the action of living organisms.
As compared to living, biotics may not always be alive, but it talks for a long period. Biotic is something that has once lived or emanated from something living.
Examples like plants, animals including humans are categorized under the category of living, while products such as rubber, latex, cow dung, paper, etc are biotic products that are not living.
Therefore, as you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.

critically evaluate the role of human beings in perpetuating climate change
Answer:
Explanation:
Industrialization and use of combustible engines for daily life activities by humans has led to the production and release of a large amount of greenhouse gases (such as CO₂, N₂O, CH₄ and CFC) into the atmosphere-which prevents a large amount of heat produced from the earth moving to space.
The burning of fossil fuels by combustible engines (from cars, trains, power generating sets e.t.c) widely used by humans has led greatly to this climate change. Trees that help absolve a large amount of the most abundant man-made greenhouse gas (CO₂) has not been massively planted around, which indirectly worsens the case of global warming. Trees would have absorbed/breath in the CO₂ while producing/breathing out O₂ that could help cushion the effects of global warming.

B. Plants would remove less carbon dioxide from the atmosphere
C. An increase in organisms respiration would raise the level of carbon dioxide in the air
D. More resources would be available for animals in the area
Answer:
B
Explanation:
The effect of the carbon cycle if a tornado lands and destroys most of the trees in a forest is Plants would remove less carbon dioxide from the atmosphere.
What impact does the carbon cycle have on land?The important changes in the land carbon cycle are likely to come because of climate change. Carbon dioxide rises temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth. However, warmer temperatures also stress plants.Thus, option "B" is correct.

An ecologist is studying Dunaliella salina a single celled algae in a local pond. The pond is located near a construction site and the ecologist wants to know what affect, if any, the construction site is having on the pond, as there has been a steady decline in the Dunaliella salina population. In order to complete their study the ecologist would like to examine the organelles inside Dunaliella salina. If they would like to examine the inner structure of the chloroplasts of an already dead Dunaliella salina, what microscope would be best suited for this task? *
A.)dissecting microscope
B.)compound microscope
C.)scanning electron microscope
D.)transmission electron microscope
In the given scenario, to see the structures of chloroplast scientists can use a transmission electron microscope. The correct option is D.
What is transmission electron microscope?Transmission electron microscopes (TEM) are microscopes that visualize specimens and basically create a much higher magnification of an image using an electron particle beam.
TEMs have the ability to magnify objects up to 2 million times.
Transmission electron microscopy (TEM) is a popular method for examining the ultrastructure of organelles.
TEM generates high-resolution pictures by passing electrons through an ultrathin segment of a sample and magnifying the resulting image with a series of lenses.
The electron beam of the TEM penetrates thin slices of biological material, allowing the study of individual components of cells and organelles.
Thus, the correct option is D.
