Is it possible to have a cell without a membrane?
Answer:
Without the cell membrane, any chemical would be allowed to enter. Membranes are very important because they help protect the cell. Materials move across the membrane by diffusion. Diffusion is the movement of oxygen, nutrients, and other molecules.

What is the distance and the displacement of the race car drivers in the
Indy 500?*
A.0m,0m
B.500m,500 m north
C.500m, 0m
Answer:
Distance is 500 m and displacement is 0.
Explanation:
Distance traveled by an object is equal to the total path covered during the entire journey. Displacement of an object is the shortest path covered.
In this case, we need to find the distance and the displacement of the race car drivers in the Indy 500 m race in a circular path.
In a race, the object must reach the initial position after some time. It means that the final and the initial position is the same. As a result, the shortest path covered i.e. displacement of the car is equal to 0. On the other hand, total traveled distance is 500 m.

Proteins-large complex molecules-are major building blocks of all living organisms. Discuss the following in relation to proteins.
The chemical composition and levels of structure of proteins
Subm
Answer and Explanation:
Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.
The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.
In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).

What is the difference between Primary and Secondary Succession?
Answer:
Some differences between primary and secondary succession are:
-Secondary succession happens on a previously existing community that has been cleared.
Another difference would be:
-Pioneer species for secondary succession are adapted differently- they grow quickly, can disperse quickly and have a short life span
And finally:
-Primary succession develops a new community from scratch

Cytokinesis – division of the cytoplasm resulting in two identical d_______________ cells.
Answer: daughter
Explanation: Cytokinesis results in the division of cytoplasm in a parental cell, creating 2 identical daughter cells.
Hope this helps!
Cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.
What is the significance of cytokinesis in mitosis?It is very important in mitosis because it aids in the division of two cells from one cell during the cell division process and results in the formation of two genetically identical daughter cells; without cytokinesis, the chromosomes would remain in the same cell, resulting in mutation as multinucleated cells are formed in such a process.
Hence, cytokinesis, the division of the cytoplasm resulting in two identical daughter cells, is caused by the mitosis process, as here the two daughter cells get an equal amount of the genetic contents.

Explanation:
Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
Explanation:
what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

Explanation:
where is sugar removed and how can you tell
Explanation:
What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.
It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.

Aspirin makes the blood thinner and prevents blood clotting which causes heart attack. i) What type of rupture did Suman suffer from? ii) What did the doctor advise her to do? Why do you think so? iii) What is the cause of Amit's heart attack? iv) Why do doctors give Aspirin to the heart patient?
Answer:
Aspirin is administered in patients who produce blood hypercoagulation, that is why it is prescribed in order to antiaggregate platelets or platelet thrombi, this is how the platelets do not add or encompass each other and do not generate obstructions in the blood vessels to trigger an AMI (acute myocardial infarction) or CVA (cerebrovascular accident.)
Explanation:
Aspirin is an anticoagulant that is made up of N acetylsalicylic acid, that is, by an acid that inhibits the union of platelets with each other, that is why these in systemic situations where there is a tendency to hypercoagulation of the blood is a benefit for the patient .
Amit's infarction is caused by a platelet thrombus that obstructs the arterioles that supply the cardiac muscle tissue, that is, the coronary arteries. When these arteries are blocked by a platelet engulfment, the irrigation does not oxygenate the tissue and it suffers a transient hypoxia or anoxia that leads to partial necrosis and even in some cases of more serious situation it could be total where the person loses his life.
