Biology
1 answer:
bija089 [108]3 years ago
4 0

Answer:

Here are the labels:

6. Zygomatic bone

7. Vomer

8. Mandible

9. Maxilla

18. Sternum

19. Costal cartilage

20. True ribs

21. False ribs

22. Floating ribs

Explanation:

  • The skull comprises the 8 cranial bones that house and protect the brain and 14 facial bones that protect the sensitive organs such as eyes, nose and mouth.
  • Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
  • The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
  • The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
  • The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
  • The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.

morpeh [17]

Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.

How can independent assortment help explain genetic diversity in humans? Hint: How many pairs of chromosomes are in a human dipl
Agata [3.3K]

Answer:

please give me brainlist and follow

Explanation:

Independent assortment states that all alleles are inherited independently of other alleles. This helps diversity because it helps to further the randomization of traits. If traits were always inherited together, as a "package deal", there would naturally be less diversity than the situation that exists.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell
Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
