A temperate forest is likely
to have numerous flowers from flowering
plants. Flowers are an evolutionary trend in flowering plants to attracts animals to
facilitate pollination. The flowers contain nectar that attracted birds, bees and other
nectar-sucking animals. The nectar is produced by nectaries
in hollow
tube in the flowers. Therefore for birds to access
the nectar they require to have long slender beaks as an adaptaition.
Answer:
Electric current is the flow of electrons and they carry negative charge so electrons inside an atom repels the flow where as a proton attracts the flow.
Explanation:
- Electricity is the process of flow of electrons. During the flow these electrons share bonds or even transfer them.
- These electrons get energy when the potential difference is applied to a conductor that is moving in the direction from low to high therefore, the electrons move from one to another creating electricity.
- Though the electron repels the continuous flow but proton develops the force of attraction.
Answer:
The answer is reciprocal chromosomal translocation
Explanation:
The Philadelphia chromosome (Ph) is the truncated chromosome 22 generated by the reciprocal translocation t(9;22)(q34;q11) and was first identified in 1960 in a patient with CML [3]. Translocation of the proto-oncogene tyrosine-protein kinase (ABL1) gene located on chromosome 9 to the breakpoint cluster region (BCR) gene located on chromosome 22 results in a BCR-ABL1 fusion gene on the Ph [4, 5]. Three BCR-ABL1 fusion gene hybrids encode BCR-ABL1 protein isoforms p210, p190, and p230, which have persistently enhanced tyrosine kinase (TK) activity. These aberrantly activated kinases disturb downstream signaling pathways, causing enhanced proliferation, differentiation arrest, and resistance to cell death [6, 7]. Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 protein are the most successful targeted therapy for Ph-positive leukemia.
Answer:
9) b
10) b
Explanation:
9) The heat causes the molecules to expand causing the air to be less dense because each molecule uses more space.
10) The bigger the difference between the air pressures, the faster the air moves.
