Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.
What are motor protein?Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.
Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

Explanation:
Help me I need this done by the end of the class if you are a bot you will get your answer kicked so stop
Answer:
1. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
2. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
3. it Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
4. The phosphorous cycle is slower than carbon cycle and nitrogen cycle because phosphorous is found mainly in very small dust particles. It moves very slowly from the deposits on land and in sediments and then it is transferred to the organism and from organism it is moved more slowly to the soil.
Metamorphic rocks are common when two continental plates collide because There is a lot of stress when enormous slabs of crust push together Sediment buries rocks to increase pressure O Magma bodies are common because there is a lot of melting O All of these
Answer: Metamorphic rock, estimated to be as old as 3.8 billion years, located near Isua at Qorqut Sound, Greenland.In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.
The conditions required to form a metamorphic rock are very specific. The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. Usually, all three of these circumstances are met. These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock.

After the amino acid chain leaves the ribosome, which organelle then folds, modifies, and transports the protein?
O Lysosome
O Cytoplasm
O Endoplasmic Reticulum
O Ribosome
Answer:
The endoplasmic reticulum
Explanation:
It is not the lysosome because their processes are degrading and recycling cellular waste, and involved in energy metabolism
It is not the cytoplasm because the cytoplasm doesn't do anything itself, it just provides an environment for the rest of the organelles to do their job
It is not the ribosome because the amino acid chain left the ribosome in the question
For secretory, plasma membrane, and organelle proteins, the endoplasmic reticulum (ER) is a significant protein folding compartment. Thus, option C is correct.
What is the role of Endoplasmic Reticulum in folding?A polypeptide chain cannot acquire its right structure and function without protein folding.
Chaperones are HSP that aid in protein folding. Chaperonins are multimeric complexes that fold proteins by forming hollow structures.
Numerous general activities of the endoplasmic reticulum include transporting produced proteins in vesicles to the Golgi apparatus and folding protein molecules into sacs termed cisternae.
Therefore, Endoplasmic Reticulum folds, modifies, and transports the protein.

Which of the following steps is required before biological processes can break down organic material in wastewater?
Aeration basins
Primary clarifiers
Filtration
Disinfection
The following steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.
Water treatment refers to any technique that enhances the quality of water in order to make it suitable for usage by humans in homes and offices.
There are certain processes involved in the treatment of water. These includes:
screening and pumpinggrit removalprimary clarifiersaerationsecondary clarifiersFiltrationDisinfectionoxygen uptakeIn the screening and pumping process, materials and objects are removed from the entering wastewater using screening machinery. The extracted material is cleaned, crushed, and disposed of in a landfill.
In the grit removal, fine particle materials are eliminated from the wastewater.
Enormous circular tanks are known as clarifiers that receive the materials. Settled material acknowledge as primary sludge, is pushed to the tank's bottom, while the wastewater leaves from the top.
At the aeration stage, the wastewater receives the majority of its treatment. Pollutants are absorbed by microorganisms and turned into cell tissue, H2O, and nitrogen through biological breakdown processes.
The water treatment process was ended with filtration and disinfection to enable the water to be free from bacteria.
Therefore, we can conclude that the steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.

Lillian parents are farmers. There are two types of fertilizers on the market. Both brands claim to grow carrots fastest. Plan and design an experiment to help Lillian's parents. Identify the independent, dependent and a control variable
The experiment to help Lillian's parents will consist of planting various carrots using both kinds of fertilizers, and maintaining a constant carrot type, amount of light, and amount of water throughout each plant.
In order to perform an accurate experiment, we need to identify three kinds of variables:
Independent variableDependent variableControl variableIn an experiment, the Independent variable is one whose value does not depend on the others. What this means is that this variable will not react to changes that occur in others. In this experiment, the independent variable is the fertilizer, given that it is not affected by the species of carrot, type of soil, or any other variable present.
The dependent variable in an experiment is just the opposite, it is, as the name implies, a variable whose value depends on the other variables present. In an experiment, this variable represents the data that we seek to measure. For this experiment, the dependent variable is the growth rate of the carrots because it is affected by the amount of water, light, and type of fertilizer we use, as well as being what we wish to measure.
Finally, the last variable we must identify is that of the control variable, also known as the constant or standardized variable. This variable is of vital importance for the accuracy of any experiment. This variable corresponds to those factors which we maintain constant through each trial in the experiment, for the example above, it is the amount of water and light, as well as the type of carrot, Lillian's parents will use.

Answer:
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Explanation:
Factors that affect evolution.
As per the question the evolution is a gradual process that includes the changes in the body of the organisms thereby making them more stronger and dynamic than others. The 4 features that affect evolution are mutations, natural selection, genetic drift, and gene flow.
The answer is thus are a major factor that leads to evolution in specie.
As per the case, Grants studied his works of natural selection. As per the changes associated with the environment, the large beak was an advantageous trait that was favored by natural selection. This leads to the increase in the size of the finches and the decline of other properties. Such a beak size, color, and even behavior. Hence the four-factor to consider are genetic drift, natural selection, adaptation and mutation (evolution).Learn more about the four factors.
