SVientiane consider Biodiversity as the study of variations among species. In order to study this, scientist require the community in which the species thrives in.
I hope this helps, tell me if you need a clearer explaination.
Answer:
-- individual damaged nucleotides that minimally impact the helix structure.
-- single stranded breaks
Explanation:
The Base excision repair is popularly known as the BER. It is defined as the cellular mechanism which repairs the DNA that are damaged throughout the cell cycle. It helps in correcting the the small base lesions which do not distort the helix structure of the DNA significantly. It is also responsible for fixing the single stranded breaks of the DNA.
Answer:
The proteins used for active transport are different for those used in facilitated diffusion
Answer:
- Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.
- Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.
Explanation:
<u>Datos disponibles:</u>
- Característica: Altura del tallo
- Alelo dominante, A, expresa tallo alto en homocigosis (AA) y en heterocigosis (Aa).
- Alelo recesivo, a, expresa tallo enano en homocigosis (aa).
Cruza: una planta homocigótica de tallo alto con una homocigótica de tallo enano (aa)
Parentales) AA x aa
Fenotipos) Tallo alto Tallo enano
Gametos) A A a a
Cuadro de Punnet) A A
a Aa Aa
a Aa Aa
F1) Genotipo: 4/4 o 100% de la progenie será Heterocigota para la característica altura del tallo, Aa.
Fenotipo: 4/4 o 100% de la progenie expresará tallos altos.
<em>Nota: Por conocimiento teórico, es posible que no sea necesario el uso del cuadro de Punnet para realizar esta cruza. Esto es porque sabiendo que uno de los parentales es homocigota dominante y el otro parental homocigota recesivo, con un solo gen dialélico involucrado en la cruza, indefectiblemente la progenie será heterocigota. Un parental solo puede ofrecer gametos dominantes para la característica mientras que el otro parental solo puede ofrecer gametos recesivos. Aún asi, el cuadro de Punnet siempre resulta útil para poder visualizar bien los cruzamientos, siempre que estos últmos involucren pocos genes. </em>
Answer:
Over the ocean air masses contain moisture which are responsible for occurring of rainfall over the area.
The air masses which are present over the land are responsible for the dry season over the period of time over an area.
Explanation:
United States is surrounded by the water bodies. Land mass get heated due to the sun. The hatred land is responsible for the removal of moisture from the air. This condition causes dry season over the area.
When the air which is present over the ocean comes across the country, these airs contains much moisture to cause precipitation. Therefore, the marshal present in the air is responsible for the precipitation.
Therefore, we can see the overall mechanism of precipitation and dry season in United States.
