Data was collected concerning Galapagos bird beak size over time. There are several species finches, and they are also known as

Darwin's Finches. These finches share the same habits and characteristics except for one; they all have different shaped and sized beaks. The differences in their beaks might be the most important aspect of their survival. Around 1977, there was a huge drop in finches with small beaks while there was a great increase in large-beaked birds. How can you explain this?

Finches adapt to the new conditions such as drought by changing the size, shape and depth of their beaks. Beak morphology varies according to drought conditions. Since after the drought, vegetation dries out and the hard, big, tough seeds remain, only the finches with deep beaks will survive. Finches adapt via their beaks to different foods sources and different local conditions.

Answer:

Darwin studied the finches which differed mainly in their beak shape and size.  These finches evolved with various beak sizes based on the availability of food. Long beaks would be helpful to pick the seed from the cactus fruits whereas short beaks would be helpful to feed on seeds at the ground level. The unavailability of food i.e seeds at the ground level would have caused such changes. Its survival of the fittest while adapting to their new or changed environment.

mezya [45]
The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.

That's intimidating, lol!

Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.

Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.

Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.

Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.

This means that choice A is true!

The afferent arteriole is _____ in diameter than the different arteriole, so that glomerular _____ is relatively high.
Marina86 [1]

The afferent arteriole is larger in diameter than the different arteriole, so that glomerular blood pressure is relatively high.

The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism.

The afferent arterioles branch from the renal artery, which supplies blood to the kidneys. The afferent arterioles later diverge into the capillaries of the glomerulus.

The glomerulus (plural glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons.

The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of intraglomerular mesangial cells. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The filtrate then enters the renal tubule of the nephron.

The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules. The resistance of the efferent arterioles causes sufficient hydrostatic pressure within the glomerulus to provide the force for ultrafiltration.

The glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall kidney function, is the glomerular filtration rate.
