Tt will cross with Tt resulting in 25% TT, 50% Tt, and 25% tt
Answer:
The two circuits of the cardiovascular system are: Pulmonary Circuit and Systematic Circuit. The pulmonary circuit is shorter than the systemic and is responsible for carrying deoxygenated blood to the lungs from the right atrium, for oxygenation. The systemic circuit is longer and leaves the aortic artery, carrying oxygenated blood throughout the body and nutrients for survival. If less blood were pumped into the systemic circuit, this amount would not be sufficient to compensate for the organism's needs, with the corresponding consequences that this would entail.
It is said that the cardiovascular system is a closed system because blood travels inside a network of blood vessels without leaving them.
Answer:
1. Transverse foramina present: Cervical
2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx
3. Receive the most stress: Lumbar
4. Attach to ribs: Thoracic
5. Articulates with hip bones of the pelvis: Sacrum
Explanation:
The vertebral column is a <u>series of 33 bones called vertebrae</u> that play a key role in organ protection, movement of body, and overall support. The column has been divided into <u>5 different regions</u> with the number of bones.
<u><em>1. Cervical Vertebrate</em></u><u>:</u> These are the group of <u>seven vertebrae of the neck</u>, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have <u>transverse foramina</u> which <u>gives passage to vertebral artery and vein</u>.
<em><u>2. Thoracic Vertebrae:</u></em> They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.
<em><u>3. Lumbar Vertebrae: </u></em>This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They <u>carry all of the upper body weight</u> providing flexibility and movement to the trunk region. This is why it can <u>receive the most stress easily</u>.
<em><u>4. Sacrum Vertebrae: </u></em>There are 5 sacral vertebral fused bones. It <u>connects to the hip bones and play role in forming a strong pelvis</u>.
<em><u>5. coccyx Vertebrae:</u></em> These are a group of 4 fused bone. There is <u>no vertebral canal due to a lack of vertebral arches</u>. They <u>provide </u>an <u>attachment site for muscles</u> ligament and tendons. They also <u>play a role in stabilization and support</u> while sitting.
Answer:
Rex is not a Tyrannosaurus rex because each of his hands has three fingers. Tyrannosaurus had only two fingers on each hand.
