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.
The answer would be B for this question. ATP is used by the mitochondria the “power house” of the cell.
Answer: An exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton of, for example, a human. i think its B
Explanation: hope this helps!
I'm pretty sure the answer would be A. Chromosomes contain one or more genes.
Answer:
1) Sucrose is synthesized in the chloroplast stroma and exported from photosynthetic cells to provide energy and reduced carbon for non photosynthetic plant cells. - FALSE
2) The enzyme rubisco is unusual in that, depending on conditions, it exhibits two different enzymatic activities. - TRUE
3) Ninety percent of the solar energy collected by a photosystem complex is absorbed when photons strike a special pair of chlorophyll molecules at the reaction center of the complex. - FALSE
4) The energy requirement expressed as ATP consumed per molecule of carbon dioxide fixed is higher for a C3 plant than for a C4 plant. - FALSE
5) The ultimate electron donor for the photosynthetic generation of NADPH is always water. - FALSE
