Clotting cascade refers to the series of reactions which take place simultaneously and result in blood clotting. The clotting cascade is a complex set of negative feed back mechanism which is used by the human body to maintain homeostasis. The clotting cascade can be triggered either by intrinsic or extrinsic release of chemical mediators. The reaction occur in this order:
Intrinsic factor < activation of common clotting pathway < platelet lipids are released < prothrombin < fibrinogen < fibrin formation < stabilized fibrin clot.
Two examples of anticoagulant medication that affect the pathway are heparin and warfarin
Answer:
long are W which means that they are stronger than the w trait of short.
1)the big word means that it will have two W traits, (or W,W), and heterozygous will mean that the seal will have one W and one w, (or W, w).
your Punnett Square will look like this W W which means that 100% of
these W W W W W
seals w W w W w
will have long.
2)Heterozygous and a short will look like this
w W w w w
w w w w w
which means that only 25% will have long and 75% will have short, this is due to how W traits will almost always beat recessive traits.
3)Now one is, (H) and two is, (h). Two Hybrid means that they are Heterozygous. This will make your Punnett Square look like this
H h
H H H H h
h H h h h
the possible Genotypes willbe H H, H h, h h.
Phenotypes, looktraits willbe One,and Two.
The bone patterns in mammalian limbs can be further traced to the bone structure of the Xenarthra species as far as its histology is concerned. There has been a bone compactness showing pattern most specifically in the femur area between the species of Cingulata and Pilosa.
Explanation:
A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher level of nitrogen and nutrients in it.
Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in the water bodies and low oxygen content, the algae grows in slower rate. Besides, slower growth of algae may also affected by the acid rain that happens near Moose lake, which is harmful for algae growth due ti the presence of sulphur.
Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
