Plant cells contain organelles, called chloroplasts, where photosynthesis occurs. However animal cells do not have chloroplasts.
The right answer is C.
During inflammation, under the influence of chemical mediators, endothelial cells (forming the blood vessels) become activated. This leads to local arteriolar vasodilation then capillary2 which causes:
** an increase in blood supply
** a decrease in the speed of blood flow
This local swelling of the blood vessels causes redness and the sensation of heat. It aims to increase the flow of blood to evacuate dead cells and toxins (detox) and provide the elements necessary for healing, including white blood cells to fight against foreign bodies.
Answer:
Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .

The question is incomplete as the options are not stated, here are the options from another website.
options for A, B and C.
respiration,
photosynthesis,
transpiration.
The answers are;
1. Respiration.
2. Photosynthesis.
3. The processes form the carbon cycle.
Explanation:
From number 1. Prices which is respiration, respiration is a process of gas exchange which oxygen is inhaled and carbondioxide is exhaled into the atmosphere.
Photosynthesis uses the carbon to produce food. This is a process where carbondioxide are used by green plants in line with light energy from the sun and water to produce glucose and oxygen.
The processes are carbon cycle because carbon cycle shows how carbon flow from the atmosphere to the biosphere.
Answer:
Las unidades de Mendel se conocen ahora como GENES
Explanation:
Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados <em>Genes</em>.
