2. What do mushrooms, trees, spiders, birds and humans all have
in common?
Answer:
They are all living organisms
Answer:
In basic biology, however, we can state two major facts that the both have in common when compared to other groups of living beings. The first one is our intracellular structure: fungi and humans present eukaryotic cells (such as plants and protozoa), which, unlike bacteria, have a membrane protecting its nuclei.

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.

How are chloroplasts like mitochondria?
Group of answer choices
They both contain DNA.
They are both found in animal cells.
They look alike.
They can both use energy from sunlight.
Answer: Chloroplasts, like mitochondria, produce energy for plant cells. Both mitochondria and chloroplasts have their own circular DNA and can function independently of the eukaryotic host cell. Hope this helps! I don't like giving direct answers I feel you should have a chance to learn.

Using information from the diagram, state one reason why the movement in the third image represents active transport
Answer:
A protein or ion has passed through the "pump" or carrier proteins and move within the cell.
Nvm short and sweet ;)
Further info..
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.
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.

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.
What describes G and why they face the watery inside and outside of the cell
Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

gene is a segment of DNA on a chromosome. How are genes related to the proteins made by a cell?
Answer:
The DNA in genes is transcribed into RNA and translated into proteins
Explanation:
The sequence of DNA in a gene is transcribed into a messenger RNA (mRNA). This sequence of this mRNA is translated into a sequence of amino acids that form a protein.
The sequence of DNA in a gene directly affects the amino acids, and therefore the structure and function of, a protein.
Answer:
The structure of the genes in a cell determines the structure of the proteins made by the cell.

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.
