Two ways:
1. In prophase I of meiosis the homologous chromosomes synapse and crossing over occurs. This switches sections of two of the sister chromatids so the outer two chromatids have the same mix of alleles as the parents and the inner two chromatids have new combinations of alleles.
2. Meiosis puts only one of each kind of chromosome in the gametes, selecting one of each homologous pair at random. Then when each gamete joins with the gamete from the other parent, there are practically infinite combinations of the alleles possible.
<span>The duct gland is comparable to the dimensions and form of a little banana, and is gift within the higher abdomen, towards the rear, nearer to the spinal chord. Whereas,the duct gland is solid containing evacuation tubes. The duct gland juices area unit created within the acinar tissues, and gone by secretion into the ducts for transport into the small intestine. The exit hole into the small intestine is named the papilla of Vater.
</span>The biliary juices are created within the tissues of the liver, then pass into the biliary ductal system. Sort of a stream, these ducts bit by bit be a part of it along to create one stream within the main epithelial duct, that exits into the small intestine at the "papilla of Vater."
Answer:
d) Y, X, Z
Explanation:
Mutant I only grows when the medium is supplemented with Z. So Z is the final product of biochemical pathway since supplying other intermediates do not lead to any growth.
Mutant III can grow if medium is supplemented with X and Z but not with Y. This means that Y is the first intermediate in this pathway since mutant III is not able to convert it into X and hence needs to be supplemented with next intermediate product X for growth.
Hence the correct order of X, Y and Z in this biochemical pathway is Y, X, Z.
Answer:
Option A
Explanation:
The carrying capacity of any given ecosystem is the maximum production that is achieved without environmental degradation. Now, since the production in option B and C is less than 500,000 tons (i.e carrying capacity of Grand Banks of Newfoundland), thus the rate of population growth would not be greatest and hence both option B and C are incorrect
Option D is also incorrect as production cannot be greater than carrying capacity or else environment will start degrading
Hence, option A is correct
Idk anything right now, I’ll comment the answer later
