Answer:
The climate change may turn diseases spread in different areas of the Globe.
Explanation:
Climate change is producing the environment to evolve constantly. We may see rising temperatures across the Globe and with it some changes on rainfall as well. Those features will dramatically change the whole environment and could possibly turn habitats, that were in the past not associated with disease vector insects, into places like the northeastern from United States and thus, mosquistoes like the the vector of malaria can be a possible disease to hit developed countries.
I believe D. because weather is current like in a month or week but climate is the usual year round.
<span>The systemic study of natural world is called natural science. It is
concerned with the understanding of natural phenomena based on collected data,
knowledge or sense of experience by means of observation and experimentation. Natural
science is subdivided into two main branches: one is biological science or life
science which aims to study life and living organisms their function,
structure, evolution, growth, distribution and taxonomy second is physical
science which is also broken down into different branches, including Earth
science, astronomy, chemistry and physics.

Answer:
50%
Explanation:
DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.
However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).
Answer:
A. Calcium would be transported to the sarcoplasmic reticulum therefore contractions would cease.
Explanation:
A muscle fibre will stop contraction immediately ATP is used up. Also, muscle contraction will end as soon as the information from the motor neuron stops. This repolarizes the sarcolemma and T-tubules, thereby closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are then pumped back into the sarcoplasmic reticulum, in order for tropomyosin to cover the binding sites on the actin strands again.
