Answer:
They are all related to cells
Explanation:
;^; can you list the answers
DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.
What are Cells?Cell is define as the smallest unit which can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts:
1. The cell membrane
2.The nucleus
3. The cytoplasm.
A nucleus is defined as the membrane-enclosed organelle within a cell that contains chromosomes. It is an array of pores, or pores, in the nuclear membrane that allow the selective passage of certain molecules, such as proteins and nucleic acids, into and out of the nucleus.
Chromosomes are define as the threadlike structures made of protein and a single molecule of DNA which serve to carry the genomic information from cell to cell. These DNA (Deoxyribonucleic acid) is a polymer which is composed of two polynucleotide chains that coil around each other to form a double helix consisting of nitrogenous bases.
Thus, DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.

A que se denomina metaboismo? Diferenca anabolismo de catabolimo da 4 ejemplos diferencia reaccion endegonica de exergonica
Answer and Explanation:
Metabolismo: El término hace referencia a todos los cambios y las reacciones quimicas y biológicas que ocurren en cada célula del organismo y que resultas escenciales para el funcionamiento adecuado del organismo (una buena nutrición, crecimiento, reparación celular, conversion energética, etc.).
Estas reacciones ocurren a lo largo de toda la vida del organismo. Cada celula toma sustancias que luego modifica químicamente para integrarlas como nuevos componentes celulares. Algunos de estos componentes son utilizados en reacciones como la respiración celular.
El metabolismo puede ser dividido en anabolismo y en catabolismo. Durante el anabolismo suceden reacciones que consumen energía (ATP) para sintetizar moléculas complejas a partir de moléculas simples, y que son necesarias para el funcionamiento del organismo. Mientras que durante el catabolismo suceden reacciones que liberan energía al deegradar o reducir moléculas grandes en otras mas simples, para que el cuerpo pueda asimilarlas y las transforme en energia (ATP). Esta energía luego será utilizada en los procesos anabólicos.
Ejemplos:
- Respiración celular: Degradación de molécula del glucosa para liberar y obtener energía y consecuentemente, moleculas mas simples (CATABOLISMO)
- Ciclo de Krebs: Oxidación de la molécula acetil-CoA y obtención de energía en forma de ATP (CATABOLISMO).
- Digestión: Degradación del alimento para obtener elementos mas asimilables por la célula y energía (CATABOLISMO).
- Degradación de ADN y ARN (CATABOLISMO).
- Fotosíntesis: Transformación de compuestos inorgánicos en orgánicos utilizando energía solar (ANABOLISMO).
- Síntesis proteica: Utiliza aminoácidos y energía para formar proteinas necesarias para el organismo (ANABOLISMO).
- Ciclo de Calvin: Usa moléculas de CO2 para formar glucosa (ANABOLISMO).
- Gluconeogénesis: Síntesis de glucosa a partir de precursores diferentes a los glúcidos (ANABOLISMO).
Reacción excergónica: reacción espontánea que se lleva a cabo y donde se produce la liberación de energía. No necesita energía para suceder.Reacción endergónica: reacción no espontánea. Necesita energía para suceder. Ocurren reacciones celulares a partir del consumo de energía.which part of the eye is sensitive to light?

A new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction. true or false
Answer:
True
Explanation:
It is true that a new species can form when a group of individuals remains completely separated from the rest of its family long enough to evolve different traits that prevent reproduction.
This happens due to physical separation of members of a population.
Geographic isolation :Geographic isolation occurs when populations are separated by geographical barriers like rivers, mountain etc.The population is separated from exchanging genetic material within the same species and results in evolution of a different trait.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?
Answer:
See the answer below
Explanation:
The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.
The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:
Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.The beginning of modern taxonomy occurred during the:

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?
Answer:
I hope this will help
Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.

Explain the difference between the three types of selection
Th difference between the three type of selection has been that stabilization selection keeps allele frequency constant, direction selection changes the allele frequency over generation, while disruptive selection maintain high allele frequency.
What is natural selection ?
Natural selection is the process by which populations of organisms adapt and change.
The 3 Types of Natural Selection
Stabilizing SelectionDirectional SelectionDisruptive SelectionStabilizing SelectionStabilizing selection is natural selection that keeps allele frequencies relatively constant from generation to generation. In other words, unless the environment changes, things stay the same.
A classic example of stabilizing selection is human birth weight Very low birth weight and very high birth weight are mutually selected to keep the mean birth weight
Directional SelectionDirectional selection is a natural selection that causes gradual changes in allele frequencies over several generations. This usually occurs when environmental/selection pressures change or when favorable new alleles emerge within the population.
Example: Recent findings show that climate change is affecting fish size in certain habitats.
Disruptive SelectionDestructive selection is natural selection that maintains high frequencies of two different allele sets. In other words, individuals with intermediate phenotypes or alleles are selected.
Destructive selection causes polymorphism: the persistence of two or more distinct phenotypes in species . This can occur in environments that exhibit variability.
For example, birds in the Galapagos Islands use their beaks to forage seeds of various sizes.
Therefore, the difference between the three types of natural selection is that:
Stabilizing selection keeps allele frequencies relatively constant from generation to generation.
Directional selection causes gradual changes in allele frequencies over several generations.
Destructive selection maintains high frequencies of two different allele sets.

Answer:
A. freeze at the same temperature at which it melts, depending on whether the temperature is rising or falling.
Explanation:
Option A is the correct.
Freezing and melting are two changes that occur in the state of matter. Freezing is known to be the change that occurs when a substance (liquid) changes to solid when there is a decrease in temperature. While melting is known to be the opposite and it refers to the change that occurs when a solid changes to liquid as a result of increase in temperature.
When substances freeze, they do so in the same temperature as they melt. This is true because both freezing and melting actually describe similar transition of matter. So, it depends whether temperature is rising or whether it is falling.
Spider silk is a material made of proteins that has a strength per gram that is five times that of steel. One feature of some of the toughest spider silks is a high proportion of β sheets that stack tightly together to form crystal-like arrays. Which amino acids would you expect to be common in such crystalline stacks and why?
Answer:
glutamic acid, because the R group could form ionic bonds
arginine, because the R group could form ionic bonds
tryptophan and tyrosine, because the R groups are small, allowing close stacking
glycine and alanine, because the R groups are small, allowing close stacking
