Explanation:

Answer:

1. Hypothesis:

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation

2.Ocean systems:

The ocean is a global, interconnected system that has regions, or basins. Water and ocean life move between these basins and up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.

3.Proteins:

a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.

4.Saturated fat molecules:

Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)

5.Enzymes:

a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

6.Prokaryote:

a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

7.Eukaryote:

an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

8.Hemoglobin:

a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a haem group.

9.Active Transport:

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

10.Phospholipids:

a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.

11.Facilitated diffusion:

Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.

Answer: Endosymbiosis theory suggests that eukaryotic cells emerge from prokaryotic cells.

Explanation:

Biologist Lynn Margulis was the first person who studied the endosymbiosis in 1960. According to him the chloroplasts and mitochondria have been originated from ancient bacteria which was free living. These organelles are found in eukaryotic cells. The chloroplasts are found in plant cells and they have a green pigment called as chlorophyll which helps in the process of photosynthesis by absorbing the sunlight energy. The mitochondria produce energy in the form of ATP by the biochemical oxidation of the food.

Answer:

25 chromosomes because after Meiosis is finished the daughter cells only have half the chromosomes as the mother cell

Answer:

Dominant

Explanation:

If both of the parents don't express the trait and the child does, then the pedigree is recessive.  According to Mendel's law, the recessive trait will only show if there are two recessive alleles.  If both of the parents of have the trait and their child does, that means that the parents are heterozygous.

If one of the parents have the trait and the child does or doesn't, then the pedigree is dominant.

Answer:Today’s apples are the results of selective breeding to improve flavor, texture. This is the same technique that humans have used for thousands of years.

Explanation:

Answer: 2009 N / 9.8 N/Kg = 205 Kg.

The mass of the motorcycle is approximately 205 kilograms.

Mass refers to the amount of matter in an object, and it remains constant regardless of the location (e.g., on Earth or in space).

Mass (kg) = Weight (N) / Acceleration due to gravity (N/kg)

Given that the weight of the motorcycle is 2,009 newtons and the acceleration due to gravity is 9.8 N/kg, we can calculate:

Mass (kg) = 2,009 N / 9.8 N/kg ≈ 205 kg

So, the mass of the motorcycle is approximately 205 kilograms. The weight of an object is the force with which it is pulled towards the Earth due to gravity. In this case, the motorcycle weighs 2,009 newtons, which means it experiences a force of 2,009 newtons due to the gravitational pull of the Earth.

Amino acids, long considered simply substrates for protein synthesis, have been recently shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.

Explanation:

The correct tRNA with the anticodon (complementary 3 nucleotide sequence UAC) binds to the mRNA using the ribosome. This tRNA delivers the correct amino acid corresponding to the mRNA codon, in the case of the start codon, this is the amino acid methionine.

They have been shown to act as modulators of intracellular signal transduction pathways typically associated with growth-promoting hormones such as insulin and insulin-like growth factor-1.

La respuesta correcta para esta pregunta abierta es la siguiente.

No sabemos cuántos integrantes participan en tu actividad. No lo mencionas.

Lo que podemos hacer es ponerte otro ejemplo para que tú desarrolles los que necesites.

La situación sería la siguiente.

Cada vez que entro al restaurante de mi tía Lola, todos mis sentidos se despiertan por la cantidad de comida que hay en la cocina, los colores de las frutas, los tonos de las verduras, los olores de los condimentos, y las texturas de la carne, el pescado y el pollo. Ese ambiente me transporta a un festín de sabores.

Este ejemplo es valido porque puedo ver los colores diversos y fulgurantes, puedo oler los aromas de los diferentes condimentos, puedo escuchar el sonido de las cocineras cortando y guisando, además de que puedo sentir las texturas de los alimentos crudos al tocarlos.

Answer:

None of the above.

I'm pretty sure the Sun is the main source of energy.

Explanation:

Here is what I found:

Energy from the sun is the primary source of energy for the earth's ecosystem. The sun's energy is collected and processed by plants through photosynthesis and converted into food for animals. Without the sun, animals would not exist. Food is stored energy and essential elements like carbon, nitrogen and hydrogen.

The main source of energy for both plants and animals is glucose. Therefore, the correct option is option C.

The process of photosynthesis, which plants use to transform solar light energy into chemical energy, makes plants one of a kind. Here, plants use the energy from sunlight to change water and carbon dioxide into glucose, a simple sugar, and oxygen. Plants require glucose as a vital source of chemical energy in order to grow, reproduce, and perform other metabolic functions. The majority of life on Earth gets its energy mostly from this conversion of solar energy into chemical energy. On the other hand, sunlight cannot be used by animals as a direct source of energy. They instead rely on eating plants or other animals to meet their energy needs.

Therefore, the correct option is option C.

1-In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

Answer:

Many substances do not dissolve in water easilyand that is because they are non-polar and do not interact well with water molecules. A common example is oil and water. Oil contains molecules that are non-polar, thus it doesn't dissolve in water so easily.
