The suffix in the medical word hematocrit means​ ________.

Answers

In the word hematocrit, the suffix crit means to separate.

The suffix 'crit' in hematocrit means 'to separate' or 'to judge'.

The suffix 'crit' in the medical term hematocrit is derived from Greek and means 'to separate' or 'to judge'. In the context of a hematocrit test, it refers to the process of separating blood cells from plasma to measure the volume percentage of erythrocytes (red blood cells) present. A hematocrit test involves centrifuging a blood sample to cause the heavy erythrocytes to settle at the bottom of the tube, which allows for a measurement of the proportion of RBCs relative to the entire blood sample. A normal hematocrit value is usually around 45%, and it is a critical indicator of the oxygen-carrying capacity of blood, with low hematocrit values indicating possible anemia.

Describe the chemical structure of a cell membrane

Answers

The cell membrane is selectively permeable to ions and organic moleculecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. 
Final answer:

The cell membrane is made up of a double layer of phospholipids, often known as a lipid bilayer, with proteins and cholesterol molecules embedded within. These components are arranged in a versatile fluid mosaic model allowing for flexibility and movement of the cell.

Explanation:

The cell membrane, also known as the plasma membrane, is the outer boundary of a cell. Its primary function is to protect the cell from its surroundings. It's composed mainly of a double layer of phospholipids (a lipid bilayer). Each phospholipid molecule has a hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails. These phospholipids arrange themselves so that the hydrophilic heads face outwards towards the watery environments, both inside and outside the cell, while the hydrophobic tails face each other inwards.

Embedded within this phospholipid bilayer are various proteins and cholesterol molecules. The proteins have various functions, including the transport of molecules across the membrane. The cholesterol molecules help maintain the fluidity (flexibility) of the membrane. This entire structure is also called the 'fluid mosaic model' of the cell membrane because the proteins are embedded in a sea of lipids, and everything can move around fluidly.

Which curve shows the course of the reaction in the presence of an enzyme--the black curve or the red curve? Which line represents the activation energy for that reaction--a, b, or c?

Answers

I found the attached image on the internet and it really helps complete this exercise.

First question:
In the presence of an enzyme, the course of the reaction is shown by the red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.

Second question:
The activation energy is represented by line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.

Explain have a fats sugars and or starch contained in seeds or milk are useful for the plant sprouting from the seed or the baby mammal

Answers

There is a lot of calories in fats that can be a good help and can be used for growth, fats are high energy molecules that help in growing organism. Fats produces carbon dioxide, water, and ATP when metabolism.  The sugars and or starch is useful in the same method, they provide calories necessary for a seed or baby animal to grow. The sugars used in glycolysis and then the products of glycolysis used in  the citric acid cycle, and the starch can be cleaved into more manageable sugars. 

Final answer:

Starch, which is made up of the glucose polymers amylose and amylopectin, is an energy store in seeds that supports the growth of the embryo during germination and serves as a valuable food source for humans and other animals.

Explanation:

Fats, sugars, and starches found in seeds or milk serve crucial roles for both plants and mammals. In the context of plants, starch is a form of energy storage, comprising two types of glucose polymers: amylose and amylopectin. When a seed germinates, the stored starch provides much-needed energy for the developing embryo. These stores are also beneficial to mammals, such as humans, who consume them as a food source. Enzymes in our digestive system, like salivary amylase, break down starch into maltose and glucose, which our cells can then absorb and use for energy.

What are the global commons? Are these being used wisely? Why or why not? What can people do to use these resources most wisely?

Answers

Final answer:

The global commons refer to shared resources that are not owned by any individual or country but are essential for the well-being of humanity. However, they are not being used wisely due to the tragedy of the commons, lack of global governance, and socioeconomic factors. To use these resources most wisely, sustainable practices, international cooperation, and education and awareness are crucial.

Explanation:

The global commons refer to shared resources that are not owned by any individual or country but are essential for the well-being of all of humanity, such as the atmosphere, oceans, and outer space. These resources are limited in nature and can be easily depleted if not used wisely. However, they are not being used wisely for several reasons.

Tragedy of the Commons: The tragedy of the commons occurs when individuals prioritize their own short-term interests over the long-term sustainability of the global commons. Everyone has an incentive to exploit these resources as much as possible, leading to their depletion.Lack of Global Governance: There is a lack of effective global governance to regulate the use of global commons and ensure their sustainable management. As a result, exploitation and mismanagement persist.Socioeconomic Factors: Socioeconomic factors such as poverty, overpopulation, and inequality contribute to the unsustainable use of global commons. People may resort to exploitative practices to meet their basic needs.

In order to use these resources most wisely, individuals and governments can take certain measures:

Sustainable Practices: Promote sustainable practices that prioritize the long-term preservation and conservation of the global commons. This includes reducing carbon emissions, implementing sustainable fishing practices, and protecting biodiversity.International Cooperation: Foster international cooperation and collaboration to develop and enforce agreements and policies that ensure the responsible use and management of global commons.Education and Awareness: Promote education and awareness about the importance of global commons and the need for their wise usage. This can help individuals make informed decisions and advocate for sustainable practices.

If a person consumed the upper amdr limit for protein as part of a diet providing 2500 kcalories, approximately how many grams of protein would be ingested?

Answers

The upper AMDR limit for protein consumption is 35% of total energy intake. In other words, if you consume 2500 kcalories throughout the day, then at most 35 percent of those calories must come from proteins such as meats, beans, seafood, and eggs. We have that 35 percent of 2500 kcalories is 875, so the upper limit on how much protein this person should consume is 875 kcalories.

Answers

In a transformation, the heat produced by friction is evidence that energy is conserved.

How enenrgy is consrved?

But altogether, neither new nor lost energy is added to the system. When moving sand makes contact with an obstruction, friction is generated that causes it to stop, and the kinetic energy of the contact is converted to thermal energy or heat.

Energy cannot be generated or destroyed, says the law of conservation of energy, heat produced by friction is evidence that energy is conserved.

The overall quantity of energy is constant during all transformations. All of the initial energy will be accounted for if you sum up all the new forms of energy that result from a transition.

Therefore, in reality, friction's ability to generate heat is proof that energy is conserved.

Large predatory fish usually are found at the 3rd and 4th trophic level of an energy pyramid. what does this mean in terms of energy loss

Answers

Autotrophs, plants, are the 1st trophic level and they get 100% energy from the sun. They use 90% in metabolism and pass on 10% to the herbivore that eats them, the 2nd trophic level. The herbivore uses 90% of that energy consumed and passes on 10% to the next level: 1% of the original energy from the sun. When the herbivore animal is eaten by a carnivore (3rd trophic level), it passes on 10% of the energy it had consumed: 0.1% of the original energy from the sun. If that animal is eaten by another (4th trophic level), it will be consuming 0.01% of the energy that first came from the sun.

Final answer:

Large predatory fish are located at the 3rd and 4th trophic levels of an energy pyramid. There is a significant loss of energy as it moves through the trophic levels.

Explanation:

Large predatory fish typically occupy the 3rd and 4th trophic levels of an energy pyramid. This means that they consume organisms from lower trophic levels, such as herbivores and smaller carnivores, to obtain energy. However, there is a significant loss of energy as it flows through the trophic levels, resulting in less energy being available at higher levels. Only about 10% of the energy from one trophic level is transferred to the next level, with the remaining 90% being used for metabolic processes or lost as heat.
