Explain whether you think judy's family occurrences of breast and ovarian cancers are sporadic, hereditary, or familial.

Sporadic cancer is cancer by chance, there is no relative with the same type of cancer. Familial Cancer, on the other hand, is a combination of genetic and environmental factors. Hereditary cancer, moreover, happens when a defective gene is passed from parent to child. Breast and ovarian cancer fall under hereditary cancer though it does not mean that if either of the parents have these types of cancer, the offspring will definitely acquire it. If either of the parents has the defective gene for breast or ovarian cancer, the offspring has higher chances of having the aforementioned cancer.

Match the following:Part A1. Transverse foramina present.2. No canals or foramen present. It articulates superiorly with the sac

Stels [109]

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 series of 33 bones called vertebrae that play a key role in organ protection, movement of body, and overall support. The column has been divided into 5 different regions with the number of bones.

1. Cervical Vertebrate: These are the group of seven vertebrae of the neck, 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 transverse foramina which gives passage to vertebral artery and vein.

2. Thoracic Vertebrae: 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.

3. Lumbar Vertebrae: This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They carry all of the upper body weight providing flexibility and movement to the trunk region. This is why it can receive the most stress easily.

4. Sacrum Vertebrae: There are 5 sacral vertebral fused bones. It connects to the hip bones and play role in forming a strong pelvis.

5. coccyx Vertebrae: These are a group of 4 fused bone. There is no vertebral canal due to a lack of vertebral arches. They provide an attachment site for muscles ligament and tendons. They also play a role in stabilization and support while sitting.

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of

ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.
