Answer:
Las instrucciones que determinan todas las características y funciones de un organismo se encuentran en su material genético: el ADN (ácido desoxirribonucleico).
El conocimiento del ADN, su estructura y función, fue determinante para el desarrollo de la biotecnología moderna.
La estructura de doble hélice del ADN, que los investigadores James Watson y Francis Crick propusieran en el año 1953 proporcionó respuestas a muchas preguntas que se tenían sobre la herencia. Predijo la autorreplicación del material genético y la idea de que la información genética estaba contenida en la secuencia de las bases que conforman el ADN.

active transport
or
passive transport
Answer:
Passive transport
Explanation:
Passive transport is transport of substances without the requirement of energy. In contrast, active transport is the movement of substances that requires energy.
In the picture, the molecules are moving from a high concentration to a low concentration. This is transport down a concentration gradient, rather than against a concentration gradient.
Transporting molecules down the concentration gradient does not require energy, and is therefore passive transport.

Describe three adaptive advantages of the mammalian anatomy. (For school only)
Answer:
Mammals have stronger more stable jaws because of the single bone structure.
Relatively larger brains require a high metabolic rate.
Internal heating allows mammals to remain quick and active in cold climates.
No eggs. Mammals have well-developed offspring that they can keep it safe inside their body until the time it is ready to be in the outside world.
Four legs under the body. It allows mammals to be highly developed when it comes to speed.
Fur. It protects the mammals’ skin.

○ HURRY I HAVE TO TURN THIS END ANSWER ALL○
Answer:
The fish dies.
Explanation:
Well, naturally, salt water fish need salt water to survive. They are so used to the salt that the salt solution is critical in their bodies. With the fresh water, the fish will get water sucked into its cells, until it's filled to the brim and eventually dies.
Answer: lyse
If cells do not get the right type of food/water, they will shrink and die. They will shrivel, and the cell may destruct. So, the answer is they will get smaller and shrivel (lyse.)

A student is studying cell structures and organelles. He wants to create an explanation of how the various organelles interact to meet the cell’s need for proteins while preventing too many proteins from collecting inside the cell. Which of the following would be the BEST explanation for the student to use?
A.
The ribosomes that cover the rough endoplasmic reticulum manufacture proteins. These proteins are sent to lysosomes where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by the Golgi apparatus.
B.
The surface of the smooth endoplasmic reticulum manufactures proteins. These proteins are sent to the Golgi apparatus where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.
C.
The ribosomes that cover the Golgi apparatus manufacture proteins. These proteins are sent to the smooth endoplasmic reticulum where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.
D.
The ribosomes that cover the rough endoplasmic reticulum manufacture proteins. These proteins are sent to the Golgi apparatus where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.
D. The ribosomes that cover the rough endoplasmic reticulum manufacture protiens. These protiens are sent to the Golgi Apparatus where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.
The statement that reveals the best explanation for the student to use while studying cell structures and organelles is as follows:
The ribosomes that cover the rough endoplasmic reticulum manufacture proteins. These proteins are sent to the Golgi apparatus where they are modified and sorted based on their destinations. Proteins no longer needed by the cell are broken down by lysosomes.Thus, the correct option for this question is D.
What do you mean by Cell organelles?Cell organelles may be defined as the type of subcellular structure which are present in the cytoplasm of the cell and has one or more specific jobs to perform in the cell. Some examples of cell organelles are the endoplasmic reticulum, mitochondria, lysosomes, Golgi bodies, etc.
Ribosomes are known as the site of protein synthesis which are present over the surface of the rough endoplasmic reticulum. These synthesized proteins are then migrated to the Golgi bodies through secretory vesicles where they are modified and sorted based on their destinations.
The waste proteins or those proteins which are now not required by the cell in order to accomplish metabolic functions, these types of proteins are degraded by the Lysosomes.
Therefore, the correct option for this question is D.

In a healthy ecosystem, which trophic level should
have the most energy?
Answer:
primary consumer
Explanation:
I'm doing this because it need 20 characters
The maximum concentration of energy is found in an ecosystem's fourth tropic level, or the first trophic level of the food chain.
What is the trophic level?Because it has the greatest energy, the first tropic level has the highest biomass. The lowest and greatest level of the pyramid is the producers, and it contains the most energy.
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Therefore, the biggest concentration of energy is found in the initial trophic stage, which is known as the foundation of an ecosystem. This energy is transferred to organisms at other trophic levels.
