An example of a scientific law is Newton's first law.

Explanation:

It says that every object will remain at rest or in uniform motion in a straight line unless forced to change direction by the action of an external force.

An example of a theory in science is the Big Bang theory. It is something that someone came up with that is a rational explanation to explain why or how something happened or came into place.

Answer:

Darwin's opinion seems to have changed over time from his original remark in the 1861 3rd edition of The Origin of Species.

Oparin and Darwin’s ideas about the Origins of life are not immediately considered to be part of a scientific theory about the origins of life on earth because the ideas they proposed were difficult to test or observe.

According to the Oparin hypothesis life originate from inorganic molecules, like amino acids considered to be formed first, and then combines to form complex polymers.

This hypothesis has no scientific proof due for this reason the idea of Oparin idea was not immediately considered to be part of a scientific theory.

The theory given by Darwin challenged the idea that God is the creator of all animals and plants that are present on earth and there were no proper pieces of evidence to prove this theory when it is published to convince several scientists.

Due to a lack of pieces evidence and scientific proof, Oparin and Darwin's ideas about the Origins of Life on earth are not immediately considered to be part of scientific theory.

Answer:

See the answer below

Explanation:

In double-stranded DNA, the ratio of purine bases (Adenine and Guanine) and that of pyrimidine bases (Thymine and Cytosine) is 1:1 according to Chargaff's rule. This means that the percentage of Adenine must be equal to that of Guanine while that of Thymine must also be equal to Cytosine.

However, in the case of the newly isolated viral strain, the amount of Adenine (25%) and Guanine (55%) vary while that of Thymine (10%) and Cytosine (20%) also vary. This is in contrast to Chargaff's rule. Hence, the isolated virus is a single-stranded DNA virus instead of a double-stranded.

Answer: Countertransport

Explanation:

Cotransport is a type of active transport of substances through a biological membrane. It is characterized by the simultaneous transport of two or more substances, hence its name, and is common in small organic molecules, such as glucose or amino acids, especially in epithelia of absorption and secretion, such as the small intestine and renal tubules. The cotransport can be of two types, simporte or antiport.

In both cases, one of the substances moves in favor of its gradient and the other against it. In electrochemical gradients there is potential energy stored and when a substance moves in favor of its gradient this energy is released.

In contransport, the transmembrane protein responsible for co-transportation, is able to use the energy stored in the electrochemical gradient of a substance to move the other substance against its gradient. The electrochemical gradient from which the energy for transport comes is maintained by ATPases, which consume ATP. Since the co-transporter does not directly consume ATP, the co-transport is classified as secondary active transport, while the ATPases perform primary active transport. So, ATPases consume energy to create a gradient and then co-carriers use the energy from the gradient to transport another substance.

In the case of Countertransport, the cell transports two types of molecules in the opposite direction across the membrane. Countertransport is a type of antiport exchange. The key point regarding countertransport is that it transports ions or molecules in opposite directions. Thus, one molecule leaves the cell while the other enters at the same time through the membrane.  In addition, this is a type of secondary active transport that uses electrochemical gradient to drive the movements (as it was explained before). Countertransport can mediate the exchange of the same solutes or different solutes. The sodium-calcium exchanger, the Na+ / H+ exchanger and the Cl- / bicarbonate exchanger are examples of countertransport.

Answer:

Carbon enters all food webs, both terrestrial and aquatic, through autotrophs, or self-feeders. Almost all of these autotrophs are photosynthesizers, such as plants or algae. Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose.
