The direction of shell coiling in the snail Lymnaea peregra results from a genetic maternal effect. An autosomal allele for a ri

ght-handed, or dextral, shell (s+) is dominant over the allele for a left-handed, or sinistral, shell (s). A pet snail named Martha is sinistral and reproduces only as a female. Which one of the following statements is true?
a. Martha's genotype must be SS. T or F
b. Martha's genotype cannot be Ss. T or F
c. At least some of Martha's offspring must be sinistral. T or F
d. Martha's sisters must be sinistral. T or F

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c wee
mars1129 [50]

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.

Why are biologists still debating the classification of protozoans? A. Biologists never agree on anything. B. There are estimate
miskamm [114]

Answer:

B

Explanation:

Answer B is correct:

Because the biologists are continuing to learn more and more about such minute organisms, protozoan systematics – that is,  the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a  topic of debate and change, still today.

Some of the rather  LARGE and unwieldy taxonomic groupings of past years are  particularly subject to revision with expansion of and  refinement in the knowledge about the members of those –  and related – assemblages. Paradoxically, the protozoa  themselves are becoming more difficult to define with  precision as our information about them and other microbial assemblages increases. Thus, presenting a single  satisfactory circumscribed definition for them is not an  easy task.

...

Answer A sounds so funny.

Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

...

Hope this answer can help you. Have a nice day!
