The bald eagle and the black bear are tetrapods, which means that they both have four limbs along with the digits. This shows that they both are the descendants of the four-limbed ancestors. However, the limbs of the bear and the bald eagle have different functions. The forelimbs of both these organisms serves different purpose. Hence, their limbs are homologous organs. The homologous organs are those which have the same ancestry but the functions are different.

Alecsey [184]

Differences: Their basic anatomical structure became adapted for different habits and habitats.

They have different numbers of carpals, phalanges, and different lengths and shapes of bones. Plenty of ways, actually!

12. DNA in organisms cells

13. The organism may share a common ancestor.

14. Humans and dogs have similar shape and length of bones. You could also say dogs and whales have the same number of bones but that’s kinda a sucky observation.

Mengapakah jisim udara tidak diukur dengan neraca tuas<br>​
ra1l [238]

Answer:

Ia tidak mempunyai badan fizikal.

Penjelasan:

Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.

_______ fungi are those species that occur as either molds or yeast, depending on environmental conditions such as temperature a
Tasya [4]

Dimorphic fungi are those species that occur as either molds or yeast, depending on environmental conditions such as temperature and nutrient availability.

Dimorphic fungi are fungi that can exist in the form of both mold and yeast. This is usually brought about by change in temperature and the fungi are also described as thermally dimorphic fungi. An example is Talaromyces marneffei, a human pathogen that grows as a mold at room temperature, and as a yeast at human body temperature.

The term dimorphic is commonly used for fungi that can grow both as yeast and filamentous cells, however many of these dimorphic fungi actually can grow in more than these two forms. Dimorphic is thus often used as a general reference for fungi being able to switch between yeast and filamentous cells, but not necessary limiting more shapes.

Some diseases caused by this fungi are:

  • sporotrichosis
  • blastomycosis
  • histoplasmosis
  • coccidioidomycosis
  • paracoccidioidomycosis
  • talaromycosis
  • candidiasis

Several species of dimorphic fungi are important pathogens of humans and other animals which  includes :

  • Coccidioides immitis
  • Paracoccidioides brasiliensis
  • Candida albicans
  • Blastomyces dermatitidis
  • Histoplasma capsulatum
  • Sporothrix schenckii

What do you predict would be the result for a person with an impaired vestibular apparatus? Explain.
babunello [35]
Each ear should have vestibular apparatus which consist of saccule, utricle and three semicircular canals. The organ can detect horizontal acceleration, vertical acceleration, and rotational acceleration. Impaired vestibular apparatus will result in losing the sense of balance. 
The organ is very sensitive as it was able to detect a small acceleration. That is why most disease in the vestibular apparatus will result in an acute(fast onset) fake perception of acceleration, called vertigo.
