where does natural selection happen ?
Answers
Answer:Natural selection occurs in nature obviously. There are quite a few reasons natural selection happens. One of the reasons natural selection occurs is because sometimes more offspring are born but not all of them survive.

Explain Genes in a expert way i will give bfrainlest who has the best answer
Answers
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.

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.
Answers
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.

5. Why Some on Igneous rocks dard and other light ?.
6. What are the 3 major types of sedimentary rocks?.
Earth Science.
Answers
Answer:
5) The different elements present in the different igneous compositions will form different minerals. Rocks with high amounts of iron (Fe) tend to form minerals that are dark in color (such as olivine and pyroxene). As result, mafic rocks tend to be dark in color and felsic rocks tend to be lighter in color.
6) There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.

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.
Answers
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

Five strands of mRNA are depicted here, numbered 1-5. The mRNA sequence labeled number
1 indicates the codons that result from the transcription of the original, unmutated DNA. Identify
the statements below that accurately describe the impacts of the mutations shown based on the
illustrations. Select ALL THREE answer choices that apply.
A). 2 is a silent mutation since the same number of codons are being coded for, resulting in a
protein with intact functionality.
B). 3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's
function is significantly altered.
C). 3 and 4 are missense mutations, with only single changes to the genome that result in single
changes to the protein, whose function is intact.
D).4 is the nucleotide insertion, resulting in a frameshift mutation. The protein's function is
significantly altered.
E). 5 is codon duplication, with three additional bases, which can result in a protein with
significant functionality changes.
Answers
Answer:
i think its a,c,e
Explanation:
let me know if its wrong tho
The statement '3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's function is significantly altered' is correct.
What is a mutation?A mutation is a genetic change in the nucleotide sequence, which can be used to encode a protein.
A mutation deletion is the loss of one or more nucleotides of the original sequence, which changes the open reading frame (ORF) of the resulting protein.A synonymous mutation is a nucleotide modification that doesn't change the amino acid that will be added to the protein during translation.In conclusion, the statement '3 is the single nucleotide deletion, which causes a frameshift in the codons. The protein's function is significantly altered' is correct (the remaining statements are false or the information is incomplete).

Answers
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.
