They come from the atmosphere, since plants use carbon dioxide to produce carbohydrates :)
The answer is C(An Allele).
Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.
Answer:
The correct answer is : nervous system.
Explanation:
Irritability is one of the key aspect life which is deal with being able to response or change according to the stimuli that is occur and disturbs the homeostasis of the body which is maintaining the body environment for living.
Nervous system is deal with the irritability by sensing the stimuli in which change occur it can be physical stimuli such as temperature, light, or sound or chemical stimuli such as pH, ions, amount of required chemical or biological stimuli such microbes in body. All these stimuli are sense b the sensory neurons and then send these signals to brain or spinal cord in order t act and respond accordingly to maintain homeostasis.
Thus, the correct answer is : nervous sytem.
Answer:
Genes.
Explanation:
Genes are present on DNA that are inherited from parents to their offspring. Genes may be defined as the segment of DNA that ultimately form a particular protein product.
The particular trait of an organism is determined by the specific combination of the inherited genes. The genes are nearly same in all the human beings and there mutation can cause observable phenotype traits.
Thus, the correct answer is option (2).
