What do birds have that distinguishes them from other organisms?a. Four-chambered he21
c. Amniotic eggs
b. Wings
d. Feathers

Answers

Answer 1
Answer: The answer is d. Feathers.

Feathers are epidermal growths characteristic only for birds and it is the trait that distinguishes them from the other organisms. 

The other three characteristics they share with other organisms:
- Four-chambered heart is a characteristic of crocodiles, birds, and mammals.
- Reptiles, birds, and mammals, belong to the group of Amniote, which means their eggs are amniotic. Amniotic eggs are either laid on land or retained inside the mother, unlike anamniotic eggs that are laid in the water.
- Wings are characteristic for birds and some mammals, such as bats. But their wings are analogues which mean they evolved independently.

According to a recent encyclopedia entry about dog breeds, Labrador retrievers come in two specific breeds: English and American. The article cites six studies from several scientific journals about dog breeding showing that males of both breeds usually average 29-41 kg (65-90 lb) in weight, and females usually average 25-32 kg (55-70 lb) in weight. Anna’s female Labrador retriever weighs 38 kg (83 lb). What does Anna’s dog’s weight indicate about the reliability of this source?

Answers

Final answer:

Anna's dog's weight falling outside the average range doesn't necessarily indicate the source is unreliable as it could be affected by individual variability. A broader sample would need to be assessed. Fur color, unrelated to weight, is determined by genotypes.

Explanation:

Anna's female Labrador Retriever being 38 kg (or 83 lb) falls outside the average weight reported in the encyclopedia for female Labradors, which is 25-32 kg (or 55-70 lb). However, these weights are averages and there can be exceptions due to factors such as individual genetics, diet and physical activity level. But, if a large number of Labrador Retrievers greatly exceed or fall below these averages, then it could indicate a problem with the reliability of the source. It's also important to cross-verify such information with other reliable sources. Meanwhile, the fur color is not associated with the weight, but based on alleles. For example, the ee_ genotype makes a Labrador yellow and B_E_ genotype turns it black.
