Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Beta-blockers decrease heart rate and blood pressure. Answer:D
It is a drug that might be used specifically to reduce heart rate in cardiac patients. The drug is also referred to as beta-adrenoceptor blocking agents and are prescription-only medicines (POMS).
I believe its A because a bonds with t g bonds with c and c bonds with g, translated to rna it's UCG.
The answer is Lionfish
are native to the tropical Pacific. There are no natural water routes of warm
water between the Pacific and Atlantic oceans.
Invasive species is a species that colonizes an environment
in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally
found in the indo-pacific, which is their
native environment. However, their presence
in the eastern United States has have threatened
the ecosystem of the region. The fish has decimated fisheries and reef
ecosystem since they also don’t have natural predators in the region. Therefore,
their population explodes unchecked.
Answer:
radioactivity will not be able to tell the difference between the DNA and proteins
Explanation:
It seems that the experiment will fail to show what Hershey and Chase showed because they modify some of the aspects. These modifications will cause changes to the results, the main one being that radioactivity will not be able to tell the difference between the DNA and proteins. This is because Amino Acids are proteins that also contain nitrogen atoms, thus labeling the nitrogen would include all DNA and proteins. This being the main reason why Hershey and Chase decided to label the DNA instead.
