I think it is a 50-60 percent chance. More boys are produced in the world than females at the moment, which might explain the reason some people are single.
The correct answer is +/-.
There are different types of interactions and relationships between the various species of an ecosystem. If both species benefit from an interaction, then we talk about a mutualistic interaction which is symbolized by +/+. There are competitive interactions where both of the species are affected negatively and are symbolized as -/-. In this example, while the lion pride is benefited by the interaction, the African wild dog is excluded from specific areas of the ecosystem and therefore the species is disadvantaged. This relationship is symbolized as +/-.
3) Heredity because Heredity is defined as the characteristics we get genetically from our parents and our relatives before them.
Answer:
7.5cm
Explanation:
Velocity vs Time Graph:
When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.
Velocity vs time graph:
Is shown in the attached image
A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.
Height of the triangle is the velocity (v) = 0.75m/s
The base of the triangle is the time interval (t) = 0.2sec
Distance travelled = Area of triangle
Distance travelled
= 1/2(V) * t
= 1/2(0.75m/s) * 0.2s
= 0.0075m
=7.5cm
Thus, during one beat blood flows 7.5 cm
Answer and Explanation:
There are three basic steps as initiation, extension and termination which occur in both eukaryotes and prokaryotes. For transcription of a gene to occur, the DNA double helix unwinds over a short region.
initiation: RNA polymerase enzyme is linked to specific portions called as promoter in DNA to start RNA synthesis after the DNA unwinds.
Elongation: the enzyme synthesizes RNA strand along the DNA chain.
Termination: RNA synthesis continues along the DNA strand until it encounters a signal representing termination of the process. The termination process happens as the transcription complex separation takes place on the DNA sequence.
When assembled in the nucleus,mRNA peels off and moves to the cytoplasm. Here, it attaches to the ribosomes.Protein synthesis is started with AUG codon which is at the beginning of the mRNA-carried code. As the mRNA moves along the ribosome its information is translated into the appropriate amino acids which are assembled into a polypeptide. this is called translaton.
