Sunlight - 9th down > Needed to chemically change water...

Population - 10th down > More than one organism of the same species...

Community - 3rd down > Different populations in a specific area...

Trophic Pyramid - 4th down > Shows the energy transfers of populations...

Food Web - 6th down > Shows the feeding relationships of the food chains...

Decomposer - 8th down > Helps dead things to chemically change...

Answer:

The boiling point of water can be used to illustrate the importance of hydrogen bonds in living systems. The boiling point of a compound is the temperature at which a liquid becomes a gas.  When the temperature is high enough to separate the individual molecules from each other, they boil, or become a gas.

Answer:

A parent with one copy of a dominant allele and one recessive coded Ww for the widow's peak  is called heterozygous for a trait and has a 50 percent chance of passing on the dominant allele to each of his or her offspring, regardless of the gene inherited from the other parent.

Answer:

Due to its function to fight against disease.

Explanation:

Improvement of strength in the human body is very important because strong body helps in fighting against diseases. Strong body helps in doing physical activities and also helps in protecting itself from every type of harm. Weak human body can't fight against diseases due to weak immune system so we can conclude that improvement in human body is necessary for survival, development and health of human.

Onion epidermal cells  are frequently used to educate children to botanical anatomy or to explain plasmolysis due to their simple and basic structure and transparency.Onion epidermal cells is used for cover onion from weather  too.

Answer:

Los cromosomas están compuestos por dos cadenas largas de polinucleótidos asociados a proteínas histonas

Explanation:

Un cromosoma es una molécula lineal de ácido desoxirribonucleico (ADN) la cual está compuesta por dos cadenas de nucleótidos dispuestas en forma de doble-hélice. En el ADN, cada nucleótido está formado por una azúcar desoxirribosa, un grupo fosfato y un tipo de base nitrogenada (los cuatro tipos de bases nitrogenadas que forma nucleótidos en la molécula de ADN son Timina, Guanina, Citocina y Adenina). La molécula larga de ADN en doble hélice se encuentra asociada a proteínas histonas para formar las fibras de cromatina. Aproximadamente 150 pares de bases de la molécula del ADN se encuentran enrolladas con las histonas H2A, H2B, H3 y H4 (dos subunidades de cada una) para formar un nucleosoma, la unidad básica de la cromatina. Finalmente, es importante indicar que la molécula de ADN contiene regiones no codificantes y regiones codificantes, es decir, fragmentos de ADN los cuales son utilizados como templados para producir moléculas de ARN mediante un mecanismo conocido como transcripción. Los ARN mensajeros (ARNm) son un tipo especial de ARN sintetizados a partir de fragmentos codificantes de ADN conocidos como 'genes'.  Posteriormente al proceso de transcripción, estos ARN mensajeros sirven a su vez como templados para la síntesis de proteínas en los ribosomas, mediante un mecanismo conocido como 'traducción'.

Answer:

B. 25%

Explanation:

There is a 50-75% or about half chance that the babies bred by a Skinny Pig and a haired Skinny pig gene carrier, will have hairless Skinny pig babies. The rest of the babies will just be skinny pig gene carriers. There is only a 25% chance that 1 or so hairless skinny babies will be born in these litters.

Every time, the amount of carbon increases depending on the population that has grown on our planet. Carbon is a chemical substance that is created by human activities which are wood, coal, natural gas, gasoline, and oil, If it is burned, Carbon dioxide is released and mixing it in the air and continuously adds for as long as they keep doing it.
