Inhibitors of microtubule synthesis inhibit mitosis by preventing the formation and function of which of these?
Answer:
Mitotic inhibitors are derived from natural substances such as plant alkaloids, and prevent cells from undergoing mitosis by disrupting microtubule polymerization, thus preventing cancerous growth. ... Mitotic inhibitors interfere with the assembly and disassembly of tubulin into microtubule polymers.
Mitotic inhibitors are the drugs which stop the mitosis where 1 cell gets divided into 2 , 2 to 4 and 4 to 8 in order to form identical cells. Inhibitors of microtubule synthesis inhibit mitosis by preventing the formation and function of microtubules.
What are microtubules made up of ?
Microtubules are made up of tubulin protein where they have the ability to show assembly and dissemble same as actin filaments.
Natural alkaloids are the inhibitors that prevent these mitotic spindle fibres to show any kind of assembly or dissembly in order to prevemnt multiple growth of the cells.
The multiple growth of cells will lead to condition called as tumor which is hazardous and abnormal cell growth condition.
The microtubules has a function of support, organisation of cytoplasm, chromosome segregation and many more.
These basically makes the skeletal structure of the cell and made up of tubulin alpha and beta structures.
Therefore, natural inhibitors alkaloids stops mitotic spindle fibres to stop showing any kind of assembly.

A. The cells are completing the growth phase and entering prophase.
B. The chromosomes in each cell have just replicated, and the cells are entering mitosis.
C. Mitosis is complete and the plant cell is forming a cell plate because plants have cell walls.
D. The cells are in metaphase, and the animal cell is drawing inward where chromosomes will line up for separation.

what is the density to the nearest hundredths, of a metal with a volume of 3.00 cm3 and a mass of 8.13g?
The density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³. Details about density can be found below.
How to calculate density?The density of a substance is a measure of the mass of matter contained by a unit volume and it can be calculated by dividing the mass of the substance by its volume.
According to this question, a metal with a volume of 3.00 cm³ and a mass of 8.13g is given. The density of the metal can be calculated as follows:
Density = 8.13g ÷ 3cm³
Density = 2.71g/cm³
Therefore, the density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³.

B. Informar el comercio ilegal de especies a las autoridades competentes.
Explicación:
Informar sobre el comercio ilegal de especies a las autoridades competentes es una de las funciones del ser humano para la protección de la biodiversidad. Las personas comercian con especies ilegalmente para obtener más ganancias, pero causan daños a los organismos y la biodiversidad donde están presentes anteriormente. El comercio de especies provoca un desequilibrio en el ecosistema que afectó negativamente al medio ambiente.

Tides on Earth are influenced by
both the moon and the sun
the sun only
the moon only
neither the moon nor the sun
Answer:
The moon only
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Explain what is most likely to be different about the poorly drained portion of the pasture in the following scenario.
Situation: A farmer has noticed that, while the majority of a pasture drains well without drying out and supports lush grass and leafy herbs, one portion is often poorly drained. The soil there is hard and compacted, and it is regularly invaded by a range of wild plants, including Russian Sage, asters, yarrow, and purple coneflowers. The farmer takes soil samples to discover what is different about this portion of his pasture.
Answer:
Soil texture.
Explanation:
The texture of soil is the main reason for its hardness and compact nature because texture of soil shows the characteristics of soil. There is high concentration or ratio of clay present in the soil which makes the soil hard and compact. Due to this texture, wild plants grow in this soil texture as well as poorly drained. So we can say that the texture of soil is responsible for its hardness.
Wallace's line is a deep-water boundary that separates islands that differ greatly in their fauna, despite their close proximity and similar climate. Accordingly, these islands are assigned to two different biogeographic realms, each of which has a large number of species that are restricted to that location and found nowhere else in the world. These species are considered ____________. Group of answer choices
Answer:
endemic
Explanation:
Endemism refers to a state in which a species/population is native to a particular geographic area (e.g., an island), although if these organisms are also found elsewhere, then they are not considered to be endemic. Endemic species are generally vulnerable to suffer extinction when their habitats are irreversibly damaged, and therefore they represent biodiversity indicators that can be used as a reference to create protected 'hot spots' and centers of endemism. Some examples of endemic species include Tasmanian devils (living in the island state of Tasmania) and koalas (living in the southeast and eastern sides of Australia). On the other hand, cosmopolitan species are widely distributed and therefore they can be found in different geographic areas around the world.

When people eat simple carbohydrates, they get _____.
A. energy very quickly
B. energy slowly, over a long period of time
C. information for how to build enzymes
D. material to build muscles
Answer:
In short The Correct Answer Is A. Energy Very Quickly, Which is the most common thing gotten from carbohydrates is energy although your body can also save the energy gained from carbohydrates for later the carbohydrates itself is processed very quickly compared to slowly...
Explanation:
Carbohydrates are a main source of energy for the body; they can be metabolized to ATP fast or slow depending on the body’s needs. Insulin brings glucose from the blood into the cells to be used for energy. The cell can either use it right away for energy or store it to use later.
Carbohydrates and Blood Sugar. When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.
Some people can survive on few carbohydrates because the body can convert protein into carbohydrates to be used for energy. When people eat too many carbohydrates, often in the form of simple carbohydrates, they can gain weight because the body stores the extra carbohydrates as fat.
