Answer:
Spindle fibers move chromosomes during mitosis and meiosis to ensure even chromosome distribution between daughter cells.
Answer:
Explanation:Spindle fibers are filaments that form the mitotic spindle in cell division, i.e. mitosis and meiosis. They are chiefly involved in moving and segregating the chromosomes during nuclear division. Spindle fibers are made up of microtubules.
Go outdoors and look for ten different plants. See if you can figure out which type of seed dispersal each plant uses, and make notes about each one. Some may have more than one method of dispersal. If you find a plant that you suspect disperses seeds in a way that you haven't studied, try to figure out how the plant does it. When you're finished, write your discoveries in a list with the name of the plant you observed (if you know it; otherwise, describe the plant).
Some you wouldn't see by stepping outside, but it gives you a general understanding of what you should be looking for.
Hope this helps!

The difference between the hydrostatic pressure of the blood in the glomerulus and the opposing pressures of the osmotic blood pressure and fluid pressure in the capsular space is termed the
The difference between the hydrostatic pressure and the opposing pressures of the osmotic blood pressure and fluid pressure in the capsular space is termed the net filtration pressure. It is a fundamental pressure.
What is the net filtration pressure?The net filtration pressure can be defined as the total pressure capable of promoting the process of filtration.
The net filtration pressure can be calculated by assessing hydrostatic pressures and pressures within the glomerular capillaries.
The net filtration pressure can be estimated by subtracting the pressures that oppose filtration from the glomerular blood hydrostatic pressure.

A condition known as varicose veins is due to leaky venous valves and causes blood to accumulate in veins. Why are valves found in veins, especially those in the lower extremities
Varicose veins are a form of chronic venous insufficiency, or a defect in the veins that prevents them from pumping blood properly.
What are venous valves?These consist of two elastic flaps of tissue that alternately open and close allowing blood to flow through the valve to another vein.
These work in conjunction with the musculoskeletal system, the muscles are constantly tensing and releasing, a pattern that causes the valves to open and close as needed.
Many veins are found, especially in the lower extremities, because they have valves that act in only one direction, a tightening of the muscles results in an opening of the valves, while a relaxation of the muscles results in the closing of the valves.
Therefore, we can conclude that one of the main functions of the venous valves is to guarantee the adequate return of blood to the heart, if a return flow occurs, the blood can begin to accumulate in the veins, potentially damaging them.

Explain the process of nuclear fusion that occurs in the sun. Why is this process important?
Answer:
The energy from the Sun - both heat and light energy - originates from a nuclear fusion process that is occurring inside the core of the Sun. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.[2]
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot. The resulting energy is radiated out from the core of the Sun and moves across the solar system.[3] It is important to note that the core is the only part of the Sun that produces any significant amount of heat through fusion (it contributes about 99%).[3] The rest of the Sun is heated by energy transferred outward from the core.
Steps
The overall process of proton-proton fusion within the Sun can be broken down into several simple steps. A visual representation of this process is shown in Figure 1. The steps are:[4]
Two protons within the Sun fuse. Most of the time the pair breaks apart again, but sometimes one of the protons transforms into a neutron via the weak nuclear force. Along with the transformation into a neutron, a positron and neutrino are formed. This resulting proton-neutron pair that forms sometimes is known as deuterium.
A third proton collides with the formed deuterium. This collision results in the formation of a helium-3 nucleus and a gamma ray. These gamma rays work their way out from the core of the Sun and are released as sunlight.
Two helium-3 nuclei collide, creating a helium-4 nucleus plus two extra protons that escape as two hydrogen. Technically, a beryllium-6 nuclei forms first but is unstable and thus disintegrates into the helium-4 nucleus.
The final helium-4 atom has less mass than the original 4 protons that came together (see E=mc2). Because of this, their combination results in an excess of energy being released in the form of heat and light that exits the Sun, given by the mass-energy equivalence. To exit the Sun, this energy must travel through many layers to the photosphere before it can actually emerge into space as sunlight. Since this proton-proton chain happens frequently - 9.2 x 1037 times per second - there is a significant release of energy.[3] Of all of the mass that undergoes this fusion process, only about 0.7% of it is turned into energy. Although this seems like a small amount of mass, this is equal to 4.26 million metric tonnes of matter being converted to energy per second.[3] Using the mass-energy equivalence, we find that this 4.26 million metric tonnes of matter is equal to about 3.8 x 1026 joules of energy released per second!

The Gulf of Mexico dead zone is an area of hypoxic waters at the mouth of the Mississippi River. Its area varies in size, but can cover
up to 6,000 7,000 square miles. The zone occurs between the inner and mid-continental shelf in the northern Gulf of Mexico
beginning at the Mississippi River delta and extending westward to the upper Texas coast. Thousands of farms are located along the
Mississippi River and its tributaries and as water washes into the river after a heavy rain, it brings with it nutrients from fertilizers
added to farmland. These materials flow downriver and eventually enter the Gulf of Mexico, where they create conditions for a dead
zone: an area of low to no oxygen that results in the death of fish and other marine life. The Gulf of Mexico is a major source area for
the seafood industry. The Gulf supplies 72% of US harvested shrimp. 66% of harvested oysters, and 16% of commercial fish
Consequently, if the hypoxic zone continues or worsens, fishermen and coastal state economies will be greatly impacted. What can be
done to minimize the Gulf dead zone? Choose ALL that could apply
A)
B)
Control of animal wastes so that they are not allowed to enter into
waterways
Adjust the timing of fertilizer applications to limit runoff of excess
nutrients from farmland.
Monitor septic systems and sewage treatment facilities to reduce
discharge of nutrients to surface water and groundwater
Restrict land use in the areas surrounding the Mississippi delta to exclude
Industrial sites
Counter the effects of fertilizers on algal growth in the Gulf with the use
of chemical herbicides
D)
E
The things that should be done to minimize the Gulf dead zone include:
A. Control of animal wastes so that they are not allowed to enter into waterways.
B. Adjust the timing of fertilizer applications to limit runoff of excess nutrients from farmland.
E. Counter the effects of fertilizers on algal growth in the Gulf with the use of chemical herbicides.
It should be noted that it's important to manage nutrients efficiently in farmlands through the restoration of wetlands in order to capture nutrients and then reduce runoff.
In order to minimize the Gulf dead zone, there should be control of animal wastes so that they are not allowed to enter into waterways. Also, there should be an adjustment of the timing of fertilizer applications to limit runoff of excess nutrients from farmland.
