Answer:
Explanation:
Since it is a recessive gene, tumor suppressor genes required the inactivation of both alleles, this is usually accomplished by the mutation of one allele and a targeted homozygous deletion of the second allele. This leads to an effective inactivation of the suppressor genes with the mutations acting a a dominant negatives. This way, patients are put at a higher risk of developing cancer
Answer:Filamentous fungi may contain multiple nuclei in a coenocytic mycelium. A coenocyte functions as a single coordinated unit composed of multiple cells linked structurally and functionally, i.e. through gap junctions. Fungal mycelia in which hyphae lack septa are known as "aseptate" or "coenocytic".
Coenocytic cells are present in diverse and unrelated groups of algae, including Xanthophyceae, red algae and green algae.
In the siphonous green algae Bryopsidales and some Dasycladales the entire thallus is a single multinucleate cell, which can be many meters across. However, in some cases, crosswalls may occur during reproduction.
Explanation:The green algal order Cladophorales is characterized by siphonocladous organization, i.e., the thalli are composed of many coenocytic cells.
In contrast to the Cladophorales where nuclei are organized in regularly spaced cytoplasmic domains, the cytoplasm of Bryopsidales exhibits streaming, enabling transportation of organelles, transcripts and nutrients across the plant.

Explanation:
Todas las partes del cuerpo (músculos, cerebro, corazón e hígado) necesitan energía para funcionar.
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.
Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.
Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.
