This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
Option A) might be correct
Answer:There may be many possible alleles for any gene, but a diploid cell or animal contains only two alleles of each gene or two copies of a single allele; a haploid gamete contains one copy of each gene, so only one allele.
Explanation:
D. all of these
Explanation:
All of the provide option clearly denotes how matter are transferred between organisms.
Based on the amount of available matter the earth is conserved. Matter is only transferred and transformed as it goes between organisms and the environment.
- Plants obtain their nutrients from the soil and they use them for various life processes. Thus, matter is exchanged between the physical environment and living organisms.
- Matter is also transferred from one living organism to another. Plants are consumed animals.
- When living organism decay, their matter are released back into the physical environment.
