Answer:

microtubules

Explanation:

Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

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.

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.

A chemical formula is obtained from the number of atoms in a compound.

Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.

For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

Answer:

(3) 4 cm' and 2.0 g/cm3

Explanation:

Given:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

A dichotomous key might be considered a significantly useful tool to classify organisms.

The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Each time you choose an option, it leads you to the following description, which gets more specific each time.

Probably you might need an atlas or a dictionary to understand some of the technical terminologies.

You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.

The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

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.

Answer:

Your answer is D) Competing with native species of snakes for food

(Sorry if it is wrong)

Explanation:

Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons. Raccoons and opossums often forage for food near the water's edge, which is a habitat frequented by pythons in search of prey.

Color of seeds Mendel chose to cross

Explanation:

This variable does not depend on the other variables you are trying to measure, so it is independent.

In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.

Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).

Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.

A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

Ecological succession occurs in stages and permits a habitat to allow new species to grow in number as the habitat undergoes change. Thus C is the correct option.

Ecological succession is defined as the process through which the mix of species and habitat in an area changes over time.  Gradually these communities replace one another until a climax community like a mature forest is reached, or until a disturbance, like a fire, occurs.

There are two major types of ecological succession namely primary succession and secondary succession. Primary succession occurs when a new patch of land is formed or exposed for the first time.

Secondary succession occurs when a climax community or intermediate community is impacted by a disturbance.

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.
