Elenna [48]2 years ago
6 0

Answer: here´s why

Explanation: Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. If water is heated, its volume gradually decreases.

The coracobrachialis muscle originates on the __________.
Travka [436]

Answer:

Option C, coracoid process of the scapula

Explanation:

Coracobrachialis muscle is one of the essential muscles that is responsible for the movement of elbow along with biceps brachii and triceps muscles.  

The coracobrachialis arises from the coracoid process of the scapula. It assists the elbow in flexion and internal rotation. Musculocutaneous nerve passes through the Coracobrachialis muscle and terminates at the lateral end of the cutaneous nerve of the forearm. However, the Coracobrachialis terminates at the humerus and its medial surface

Hence, option C is correct

Anastaziya [24]

Complete question: A phylogenetic tree shows that birds and crocodiles share many features. A hypothesis based on this tree predicts that these features are present in a common ancestor. Which of these predicted traits is supported by fossil evidence?

A) four-chambered heart

You are analyzing a human pedigree for a new disease and discover that the disease occurs with the same frequency in both sexes
Natasha_Volkova [10]

Answer:

The correct answer is A. autosomal recessive

Explanation:

In an autosomal disease, the mutation occurs in the autosomal chromosome, not in the sex chromosome. In autosomal recessive disease if both the defected allele from parent comes in the child then only the child would be affected by the disease. If the offspring have single defected allele than he is said to be a carrier.

So as the defect is not in sex chromosome the disease will occur in the same frequency in both the sexes and if parents are carriers which means they are not affected by disease than 25% offspring can have the disease because out of four offspring one can get both the defected allele, one from each parent. So the correct answer is A.
