Answer: Below
Explanation:
Alligators play an important role in maintaining ecosystem balance. Sitting at the top of the food chain, alligators are top predators and help keep other animal populations in balance. By digging holes and leaving trails throughout marshes, they create habitats for fish and marine invertebrates
Answer:
The correct answer would be a lipid-soluble signal.
Signal transduction refers to the set or cascade of bio-chemical reactions take place in a cell in order to transmit the chemical or physical signal from outside the cell to inside target molecule.
It is usually initiated by receptors present on the membrane of the cell which sense the extracellular stimulus (such as ligand, hormone, pressure, temperature, pressure etc). Once activated, these receptors activate the cascade of reaction which ultimately reaches the target molecule and produces a cell's response.
In contrast, the lipid-soluble signals (such as steroidal hormones, thyroid hormone etc) enter the cell membrane without any hindrance. They directly bind to intra-cellular receptor present in the cytoplasm or on the nuclear membrane.
The hormone-receptor complex then enters the nucleus and act as transcription factor and produces the response in the form of transcription.
Answer:
1. codominance Both members of an allelic pair contribute to phenotype producing a mixture of phenotypic traits
2 . Rh factor: An inherited protein found on the surface of the red blood cell membrane
3 . hemophilia: A hereditary condition for bleeding due to the inability to clot properly
4 . holandric gene: A gene located on the Y chromosome in XY species
Explanation:
Codominance occur when a pure breeding White flower crosses with a pure breeding Red flower and gives PINK offspring
Rhesus Factor is an antigen that appears on the surface of red blood cells. it is an important factor to consider during blood transfusion.
Hemophilia is a sex-linked condition where the sufferer is unable to have a blood clot.
Holandric gene can ONLY be passed from males (carriers of XY chromosomes) to their sons
There are different types of biomes but,here`s my example
