Copernicus and other astronomers before him thought that celestial bodies followed a circular orbital path.
Answer: circular - first choice
The net force is 0 N, so the satellite will not move.
The net force is to the right at 1500 N.
The net is to the left at 1000 N.
The net is to the left at 500 N.
The net force with which the satellite move is 500 Newtonsand the satellite moves in the left direction. Thus, the correct option is D.
The net force on an object can be defined as the combined effect of the sum of all the forces such as pushing and pulling forces which are actually acting on the object. If all the forces which are pushing or pulling on an object are not balanced, then in this case a net force acts on that object which then makes the object to accelerate in the direction of the net force applied.
Net force = Sum of all the applied forces
Since, here the forces applied are in different directions.
Net force = 1000 N (towards left) - 500 N (towards right)
Net force = 500 N (towards left)
The net force has a magnitude of 500 Newtons and it is in the left direction because 1000 N is more than 500 N.
Therefore, the correct option is D.

B. Red headed females in a population will only breed with red headed males. The yellow headed females will only breed with yellow headed males. The red and yellow populations live on separate continents and rarely met in nature. The red and yellow could breed and produce fertile offspring but they normally do not. This would be an example of sympatric speciation.
C. Sympatric speciation does not require geographic isolation.
D. Red headed females in a population will only breed with red headed males. The yellow headed females will only breed with yellow headed males. This population lives in the same geographic area. The red and yellow individuals could breed and produce fertile offspring but they normally do not. This would be an example of sympatric speciation.
E. Sympatric speciation can be due to sexual(mate) selection
Answer: Options A, C and E are correct
A) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
C) Sympatric speciation does not require geographic isolation.
E) Sympatric speciation can be due to sexual(mate) selection
Explanation:
Sympatric speciation is the situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e not living in isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory which results in an uneven gene flow or disruption of alleles in new species or offsprings of such parents organisms.
o
OB. The number of alleles a parent has
C. The likelihood of an event occurring
O D. The most likely possible outcome
The likelihood of an event occurring is described as probability and is denoted as option C.
This is referred to a branch of mathematics which deals with calculating how likely something occurs.
A common example is the likelihood of a parent giving birth to
offspring with certain types of trait etc.

Answer:
it increases speed of chemical reaction
Enzymes are proteins that speed up chemical reactions by lowering the activation energy, or the energy required for a reaction to take place. This makes reactions happen more efficiently and quickly.
An enzyme is a type of protein that accelerates, or catalyzes, chemical reactions. In relation to their effect on the energy of a chemical reaction, enzymes lower the activation energy. The activation energy is the energy threshold that must be met in order for a chemical reaction to occur. By decreasing this energy barrier, enzymes facilitate the process and make it proceed faster than it would without the enzyme.
For example, let's take the digestion of food in your body. The enzymes present in your digestive system speed up the chemical reactions that break down large food molecules into smaller units. This is because these enzymes reduce the activation energy required for these reactions, enabling the reactions to happen more efficiently and quickly.
