D. They had larger beaks.

Due to the drought they would need to dig deeper for food. But their tiny beaks could not do that. So over time their beaks grew and adapted to the drought. Therefor the answer is D. They had larger beaks!

Hope this helped! <3

Explain in your own words : Are mutations good or bad for a population
solong [7]

Answer:

<h3>Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.</h3>

Write a paragraph as if you are a molecule of ammonia that will be converted to uric acid and then to urea and excreted as urine
Anna007 [38]
As an ammonia molecule, I begin in the blood stream. I pass through the heart and down the aortic trunk to the renal artery and into the kidney. Once there, I begin in the renal cortex where I find a renal corpuscle. I am absorbed by the renal corpuscle by specific gravity and descend around the nephron loop. I ascend the other side and am sent to a collecting duct. This collecting duct takes me to a papillary duct and into one of the minor calyces. This minor calyx feeds me into a major calyx, along the renal pelvis where I combine with other compounds, such as water, ions, acids, drugs, and toxins to form urea. We are sent through the hilum and down into the ureter. The ureter takes us to the bladder where we wait for urination. As we exit the bladder and are combined with creatinine and uric acid, we become collectively known as urine and are sent down the urethra to exit the body.

Answer:

Well, where are you? It's probably because we're all under quarantine. Social distancing sucks, you start to go crazy being alone. I'm sure it's just because you can't go do things or interact with people.

Most species of cyanobacteria are enclosed in a _____.
Natali [406]

Answer: mucilaginous sheath

Explanation:

These algae are known as "blue algae" because of their pigmentation or "cyanobacteria" because they are prokaryotes. Microbiologists classify cyanobacteria in the realm of Eubacteria. They are the only prokaryote algae. The cellular organization is prokaryotic, without nuclei or organelles. Respiration takes place at the level of plasmalemma and thylakoids. In the center (nucleoplasm), cells contain their genome and circular plasmids. Cyanobacteria often also have a mucilaginous sheath common to many trichomes.

These organisms contain several carotenoid pigments, particularly myxoxanthophyll, which does not occur in any other algae group. Some cyanobacteria are strictly phototrophic, others are optional: they are phototrophic when in the presence of light, but may grow in obscurity using an organic carbon source. Others can use a source of organic carbon as well as inorganic carbon, but only in the presence of light.
