The cell is covered by the cell membrane, which makes the boundary, and allows only selected materials to enter the cell or exit the cell because some material is harmful to the cellular function.
How do cells selectively accept the material?In cells having a membrane that is selectively permeable, no molecule is enter or lives in the cell. It has several protein transporters which allow the molecule to enter the cell, this maintains the cell's function.
Some inhibitors and toxic materials are responsible to inhibit general cellular functions, like metabolism, and DNA synthesis. Metabolism products made by the cell are necessary and do not allow to escape from the cell.
Therefore, for the proper functioning of the cell, it maintains to allow selective permeability of the membrane.

Karenia brevis, the dinoflagellate responsible for red tides, is ____________ , meaning it can undergo photosynthesis when conditions are right, or it can ingest bacteria, algae, and animal waste if additional nitrogen is needed.
Mixotroph organisms are capable of obtaining energy from the environment by combining autotrophic and heterotrophic mechanisms. Karenia brevis is mixotroph.
What is mixotrophy?Mixotrophy is a nutritional strategy used by some organisms that combine autotrophy and heterotrophy to obtain energy. It is widely observed in aquatic environments and especially among phytoplanktonic flagellated algae.
The development of mixotrophy depends on the environment in which the organism lives, its limiting conditions, and resources availability.
This strategy is used in aquatic environments in which light and nutrients availability is scarce. So organisms can change from being autotrophs to heterotrophs, and vice-versa, according to the environmental pressures.

In addition to cortisol, other hormones that are usually released during many kinds of stress include ______.
In addition to cortisol, other hormones that are usually released during many kinds of stress include CRH, aldosterone, catecholamines, and beta-endorphins.
What do you mean by Hormones?Hormones may be defined as a chemical substance produced in the body that governs and regulates the activity of certain cells or organs.
Corticotropin-releasing hormone (CRH) is the central controller of the hypotalamic-pituitary-adrenal axis, which is the major organizer of the body's response to stress.
Catecholamines such as dopamine, epinephrine, and norepinephrine are released in the body during stress.
Beta-endorphins modulate the effect of stress and attenuate its response in the body.
Therefore, in addition to cortisol, other hormones that are usually released during many kinds of stress include CRH, aldosterone, catecholamines, and beta-endorphins.

benefits of variation in height
Answer:
It’s nice to be tall. Tall people are more likely to get hired, get promoted and are paid better than their shorter counterparts. They can reach things from high shelves, have unobstructed views at parades, and are consistently rated as being more attractive than others. Overall seems like a sweet deal.
If you are short, you get depressed when some points out that a study in the New England Journal of Medicine suggested that shorter people are at higher risk for heart disease. However, you might find some solace from a study published in PLOS one that found that shorter people lived longer or another study that suggested that taller people are at increased risk for cancer. When it comes to whether it is better to be tall or short, there is a lot of medical research on the subject, and one half contradicts the other half.
These studies get a lot of media play because they are instinctively popular. We are obsessed with height as a society. After all, we invented high-heeled shoes to defy genetics and punish our ankles.
But every time a report claims that taller is better (or that shorter is better), headline writers seem to consistently forget that six months ago they were claiming the opposite.
But being short i also nice so if someone is making fun for your height its because their insecure about their own height
Answer:
Variation in height creates a diverse and more dynamic world, we need certain heights for certain careers as well as certain tasks.

gases do not have a definite shape because?
Answer:
Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Therefore, gases take the shape of the container and occupy the complete volume of that particular container.

Answer:
1.d. The crab expels carbon dioxide into the hydrosphere when glucose is converted into ATP.
2.The biggest changes in the land carbon cycle are likely to come because of climate change. Carbon dioxide increases temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth.
How does carbon move from living things to the atmosphere?
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
Explanation:
Converts glucose and oxygen into water and carbon dioxide, which releases energy as ATP
Explanation:
Cellular respiration is the process in which sugars are broken down into energy that can be used, so energy - or ATP - must be a product. Also, the chemical equation for the process is the following (the reactants are on left side of the arrow while the products are on the right):
C_6H_1_2O_6 + 6O_2 ⇒ 6CO_2 + 6H_2O6CO

So, since C_6H_1_2O_6 + 6O_2 represents glucose and oxygen and 6CO_2 + 6H_2O6CO

O a 900 kg car that travels 15 km per liter of fuel
A 1,200 kg car that travels 20 km per liter of fuel has the greatest efficiency.
What is Car efficiency?The amount of fuel consumed is measured in litres per 100 kilometers for example. The measure is typically used in Europe (with the exception of the UK, Denmark, and The Netherlands - see below), New Zealand, Australia, and Canada.
The lower the value, the more economical a vehicle is (the less fuel it needs to drive a specific distance). Additionally in China, Madagascar, Paraguay, Guatemala, Colombia, and Uruguay. as well as in the post-Soviet space.
Fuel economy is the amount of distance covered per unit volume of fuel consumed; for example, km/L or MPG, where 1 MPG (imperial) 0.354006 km/L. A vehicle is more economical the higher its value since it can travel farther for a given volume of fuel.
