Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?(1 point)
(A) Individuals that must compete for limited resources are more likely to have diseases that cause mutations.
(B) Individuals that have traits that allow them to outcompete others survive better and produce more offspring.
(C) Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation.
(D) Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem.
Answer:
B.
Explanation:
For A, more limited resources doesn’t mean more to mutations, mutations are random. C is incorrect, D and doesn’t explain the connection.
Natural selection occurs in individuals that have traits that allow them to outcompete others survive better and produce more offspring.
What is natural selection?Natural selection is the process by which organisms are selected for survival in their environment by natural processes which depends on the ability of the organism to adapt to their environment.
These traits enable the organism to adapt to changes in their environment.
Therefore, natural selection occurs in individuals that have traits that allow them to outcompete others survive better and produce more offspring.

(c) If the Wakame culture is maintained for an additional 120 days, predict the most likely effect on
the number of cells counted every five days. Provide reasoning to justify your prediction. (2 points)
The most likely effect this will have on the number of cells counted every five days is ;
There will be a decline in the number of cells ( Wakame )Incubation periodAs the incubation period increases the number of cells will start declining as the stationary phase has already been achieved between 25 to 30 days. also as the nutrient in the medium decreases the cells will try to adapt the the starvation which will lead to the decline in the number of cells.
Hence we can conclude that The most likely effect this will have on the number of cells counted every five days is ; there will be a decline in the number of cells ( chlorella )

What is a quantum number
Answer :
Quantum numbers are used in chemistry and quantum physics to explain the values of conserved quantities in the dynamics of a quantum system.
Quantum Number of Angular Momentum (l)
The angular momentum quantum number (l) denotes the general shape or area in which an electron exists—its orbital shape. The value of l is determined by the value of n, the fundamental quantum number. Positive values of the angular momentum quantum number range from zero to (n 1).

The unicellular spores of the fern Ceratopteris richardii are about 100 μm in diameter. Calculate the surface-area-to-volume ratio of a cube whose sides are 100 μm in length to approximate the surface-area-to-volume ratio of the fern spore cell. Show your work.
Answer:
Take 6(100x10^-6)^2 which is the surface area of it.
The volume is (100 x 10^-6)^3 this is the volume of it.
This is the surface to volume ratio, so 6(100x10^-6)^2 divided by (100 x 10^-6)^3.
Moreover the volume is 6 x 10^4

Explain Genes in a expert way i will give bfrainlest who has the best answer
Answer:
Genes are pieces of DNA (deoxyribonucleic acid) inside each cell that tell the cell what to do and when to grow and divide. Each gene is made up of a specific DNA sequence that contains the code (the instructions) to make a certain protein, each of which has a specific job or function in the body. Each human cell has about 25,000 genes.

state when this reaction occurs (fibrinogen)?
Answer:
Thrombin, in turn, catalyzes the conversion of fibrinogen (factor I)—a soluble plasma protein - into long, sticky threads of insoluble fibrin (factor Ia). Blood-clotting proteins generate thrombin, an enzyme that converts fibrinogen to fibrin, and a reaction that leads to the formation of a fibrin clot.
