Answer:
The correct answer would be option D) no gametes.
Explanation:
The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.
Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.
The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.
Thus, the correct answer would be option D) no gametes.
Answer:
B: humans inhale oxygen from plants which is used in cellular respiration to produce water
Explanation:
Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
