Thrombocytopenia term is used to describe the deficiency in circulating platelets.
Thrombocytopenia- A condition when there are fewer platelets in the blood than usual. It may result in profuse bleeding, bruising, or sores in mucous membranes and other tissues.
Mucous- The delicate lining that line a number of body compartments and organs
Platelets- Platelets, also known as thrombocytes, are microscopic, colorless cell fragments found in our blood that aid in stopping or slowing bleeding. The place where platelets are produced is in our bone marrow, which resembles a sponge and is located inside our bones. Stem cells found in bone marrow are the source of platelets, white blood cells, and red blood cells.

Sound travels faster at higher temperatures
true false
Answer:
True
Explanation:
Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly.
Therefore, sound travels faster at higher temperatures and slower at lower temperatures.
Why are elliptical galaxies important??
Answer:
Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they're frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies.
Explanation:
Answer:
Astronomers have identified and named more of the spiral galaxies because their swirling arms and brightness make them easier to spot. Elliptical galaxies are older and give off less light than other galaxies. They also have less dust and gas in them, so they don't form many new stars.

c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.
Answer:
A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
Explanation:
The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.
Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.
This is why option A is the correct one.

explain one way that HYDROGEN GAS is commercially produced
Explanation:
There are a number of ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.

What happens when you add additional lightbulbs (a type of resistor) to a series
circuit? Check all of the things that happen.
-The light bulbs will get more dim with each bulb that is added.
-The resistance in the
circuit increases with each item that is added.
- The lightbulbs will get brighter with each bulb that is added.
-The circuit will not light
Answer:
the light bulbs will get more dim with each bulb that is added
Explanation:
i dont know how to explain it, but im sure it's right.... i hope ....
When you add additional lightbulbs (a type of resistor) to a series circuit then the light bulbs will get more dim with each bulb that is added. Hence option A is correct.
What is circuit?Circuit is defined as a device constructed from various smaller electrical components that can direct electricity via itself to power bigger devices. Electricity can flow continuously in a closed circuit from the power source, to the conductor or wire, to the load, and then back to the ground or power source.
A series circuit will have increased resistance if additional light bulbs or resistors are added. As a result, the circuit's current and lamp brightness will be diminished. The brightness of each light bulb gradually lowers as more are added. This observation suggests that the circuit's current is diminishing. Therefore, for series circuits, the overall current within the circuit falls when more resistors are added.
Thus, when you add additional lightbulbs (a type of resistor) to a series circuit then the light bulbs will get more dim with each bulb that is added. Hence option A is correct.

Why does a pH of 5 produce high ATP synthase activity, but a pH of 3 and 9 very low ATP synthase activity?
Answer:
ATP synthase works best at a pH of 5, but changes in the pH of the medium can alter its enzymatic activity, decreasing it.
Explanation:
Enzymes are specialized proteins that contribute to biochemical reactions occurring faster, decreasing the activation energy.
Under ideal conditions of temperature and pH, enzymes can work at their maximum capacity, but changes in these conditions can affect the speed with which an enzyme acts.
ATP synthase, an important enzyme for ATP synthesis and oxidative phosphorylation, works best at a pH of 5 (weak acid), but as the acidity or alkalinity of the medium increases, enzymatic activity decreases.
A population of ducks lives in an area that floods many times each year. Some of the ducks are better at finding food on dry land, while other ducks are better at finding food in wet, muddy areas. Eventually, the land around the lake permanently changes from dry soil to wet, marshy mud.
How will this change to the land most likely affect the duck population?
The population will remain stable because the ducks will not be affected by this kind of change.
The population will eventually balance out so that there are equal numbers of both types of ducks.
The population will evolve so that most ducks survive no matter how they find food.
The population will evolve so that most ducks are better at finding food in wet, muddy areas.

Why do humans , bees , and flowers need glucose and not rocks ?
One of the most crucial chemicals in human biology is glucose, a six carbon aldose. Since glucose is a carbohydrate, it exists in a partially oxidized state and can give the cell a moderate amount of energy.
Because glucose is the primary catalyst for catabolism in all cells, it is significant. Since the cellular activities that comprise the complete TCA cycle and chemiosmosis rely mostly on glucose to supply energy, glucose is used to provide energy for cells. The products of each of the sequence of oxidations that glucose undergoes can effectively donate electrons, allowing them to be utilized for the process of oxidative phosphorylation to produce ATP.
