Answer:
Kinetochore and Mitotic Spindle
Explanation:
During prometaphase, mitotic spindle microtubules from opposite poles attach to each sister chromatid at the kinetochore. In anaphase, the connection between the sister chromatids breaks down and the microtubules pull the chromosomes toward opposite poles.

Some silverware is made with the element silver (Ag). Over time, this silverware will turn black (tarnish) if it is not cleaned with a special solution. Why is this a chemical change?
Answer:
The tarnish is actually the result of a chemical reaction between the silver and sulfur-containing substances in the air. The silver is actually combining with sulfur and forming silver sulfide. Silver sulfide is black. When a thin coating of silver sulfide forms on the surface of silver, it darkens the silver. That’s what we call ‘tarnish.’
The time it takes to run a mile depends on the person running speed what is the independent and dependent variable as well as the constants
Independent: The person's running speed
Dependent: The time it takes to run a mile
Constants: The mile.
-------
The independent variable stands on it's own. It will not change based on the Dependent Variable.
The dependent variable, the time it takes a person to run a mile, will change based on the Independent Variable, the person's running speed.
The constant is the mile. In an experiment, the mile, will stay the same. In each trial, it will stay the same, unlike the data for the independent and dependent variable.

suggest why a 16 years old boy or girl needs more energy than a baby
Answer and Explanation:
A 16-year-old usually needs about 2,500-3,200 calories for energy. A baby's calorie diet is around 35-50 per pound. The reasoning is that a baby does not move around as much as a teenager would. A baby cannot walk or run. A teenager however moves a lot whether to get up to go eat or to a different room.

D. autotrophs
Answer:
Humans are multicellular and heterotrophs.
Explanation:
Multicellular organisms: Multicellular organisms are those which are made up of many cells. This is because the cells of the organism have specialized into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.
Heterotrophs: Heterotrophs are known as consumers because they consume producers or other consumers.

Biology is an interdisciplinary study. Explain what that means in your own words. Give a detailed example or story that clearly illustrates the interdisciplinary nature or biology and the importance of biology in the world around you.
Answer:
Hope I helped you!
Explanation:
An interdisciplinary study means it encompasses other branches. So, biology as an interdisciplinary study encompasses other sciences. Biology can be related with other sciences like chemistry, microbiology, molecular biology, physiology, systematics, taxonomy, statistics, ecology, genetics. The allied fields are endless. All these share a common goal. Like statistics, biology, ecology, and genetics can be used in population of biology.
How does Rutherford’s model of the atom compare with Thomson’s model? They both describe atoms as small, indivisible spheres. They both describe electrons as moving around the nucleus. They both describe electrons as being surrounded by the positive matter. They both describe atoms as being made up of positive and negative matter.
Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
Both Rutherford and Thomson's model both describe atoms as being made up of positive and negative matter. The correct option is D.
What is an atom?An atom is a matter particle that truly represents a chemical element. An atom is made up of a central nucleus encased by one or more electrons. Each electron carries a negative charge.
Thomson's plum pudding the atom model contained negatively charged electrons within a positively charged "soup."
The gold foil experiment by Rutherford demonstrated that the atom is mostly empty space with a tiny, dense, positively charged nucleus. Rutherford proposed the nuclear model of the atom based on these findings.
Thus, the correct option is D.

what are the disadvantages of adding calcium oxide to fish pond
Answer:
it causes the rapid increase in PH which may harmful for the for fishes and other aquatic lives.
Explanation:
There are a lot of materials which are used to neutralize the acidity of soil.some examples of such materials are slacked lime, quick lime, and liquid lime etc. Lime increases the PH and the concentration of calcium which helps in removal of phosphate from water. Raising PH also cause to remove the carbon dioxide from the water. But keep in mind that rapid increase in PH is harmful for the fishes.calcium oxide also causes the rapid increase in Ph therefore, it is not advisable to use in fishpond.
Which biomolecule determines a person's ability to clot blood properly?
A- Glycogen
B- Lipids
C-Carbohydrates
D- Nucleic Acids
Answer:
D- Nucleic Acids
Explanation:
Blood clotting is a process whereby a person's blood coagulates due to the formation of a white fibrous protein substance called FIBRIN. The essence of blood clotting is to prevent excessive flow/waste of blood when a blood vessel is wounded.
However, certain substances are needed for this process of blood clotting to occur in our body. Some individuals lack this substances and hence bleed continuously during injury, a condition known as HEMORRHAGE. The substances such as FIBRIN, a protein needed for blood clotting is encoded by GENES which makes up DNA (a type of nucleic acid).
Therefore, NUCLEIC ACID biomolecules determines a person's ability to clot blood properly because nucleic acids make up DNA, which contains segments (genes) that encode the synthesis of proteins (fibrin) needed for blood clotting to occur. Hence, it all boils down to NUCLEIC ACIDS.

Write a paragraph about trains that were made in 1800's.
Answer:
This significant aspect of the design was transferred to later locomotives. Railways were made out of cast-iron until the 1800s. Cast iron was sadly susceptible to corrosion and it was weak, often causing it to collapse under stress. John Birkinshaw invented a more robust material, wrought iron, in 1820.

what are the function of kidney ?Kidney maintain acid-base balance of the human body is a state of delicate equilibrium by a parameter called as pH and the normal pH of the blood is 7.35 to 7.45.
The kidneys control the stable water balance in human body, filter some electrolytes from the blood, return part of them back into circulation, and excrete excess electrolytes into the urine, sodium and phosphate are dependent on the health of one’s kidneys.
The kidneys remove water-soluble waste products and toxins with urine, it produce an enzyme called renin which converts the angiotensinogen produced into angiotensin I and converted in the lungs into angiotensin II. Angiotensin II constricts the blood vessels and control blood pressure.
The kidneys produce erythropoietin, which help the body to create erythrocytes essential for the transport of oxygen throughout all the body parts.
