The FBI uses STR (short tandem repeat) analysis to identify criminals, and the FBI stores the information in a database. How many regions, or loci, of DNA are used for STR analysis? 5 13 26 30
Answer:
13
Explanation:
Short tandem repeats (STRs), also known as microsatellites, are short DNA sequences containing core repeat units of between 2-7 nucleotides (nts) which are tandemly repeated. The STR analysis is commonly used in molecular biology laboratories in order to identify DNA samples by comparing STR loci between samples. For example, the Federal Bureau of Investigation (FBI) uses 13 STR loci for the identification of individuals in the USA. It is important to note that these 13 loci are independently assorted (i.e. they are not linked), and thereby their combined use results in a very low ("nearly zero") false-positive identification rate.

Maria wanted to grow a fern in her backyard. Acting on a suggestion from a friend, she collected brown dots from the underside of a fern's leaves and then potted them. After a few days, Maria saw small fern leaves erupting from the pot. Which statement explains this phenomenon? A. The fern transitioned from gametophyte generation to sporophyte generation. B. The fern grew as a result of mitosis. C. The fern transitioned from sporophyte generation to gametophyte generation. D. The fern grew to be genetically identical to its parent plant.
Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.
Explanation:
Ferns undergo an ALTERNATION of GENERATIONS in their reproductive life cycle. That is, they alternate between an incospicuous gametophytic stage and a dominant sporophytic stage. The sporophyte produces haploid spores, which germinates into the gametophyte plant called PROTHALLUS.
The gametophyte produces gametes (male and female) which fuse together to form the diploid zygote, which eventually develops into the SPOROPHYTE plant via mitosis. In this question, the brown dots from the underside of a fern's leaves that Maria collected are the spores.
When she places them in a pot, the spores germinated into gametophyte stage, then formed sporophyte, which is the small leaves she noticed growing from the pot. From this, it can be observed that the fern is transitioning from GAMETOPHYTE generation to SPOROPHYTE generation.
Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.

Explanation:
Different evolutionary lines that encounter extremely similar forces of natural election tend to become more similar as they evolve. This is known as
Answer:
convergent evolution
Explanation:
Convergent evolution is the evolutionary process by which independent species evolve similar phenotypic traits as a consequence of the adaptation to similar environmental conditions and/or ecological niches. A well-known example of convergent evolution are the wings of birds, insects and bats that evolved separately in these different lineages. Convergent evolution is opposite to divergent evolution in which closely related organisms evolve different phenotypic traits (for example, Darwin's finches, which are closely related species that have both similar and different traits).
Which of the following are similarities that Earth’s biomes all share?
Check all that are true.

5. If an organism has 5 pairs of chromosomes and no crossing over occurs, how many different
arrangements of chromosomes are possible in the gametic cells? Explain.
Answer:
In spite of the fact that he didn't have any acquaintance with it, Walther Flemming really noticed spermatozoa going through meiosis in 1882, yet he confused this cycle with mitosis. Regardless, Flemming saw that, dissimilar to during standard cell division, chromosomes happened two by two during spermatozoan improvement. This perception, continued in 1902 by Sutton's careful estimation of chromosomes in grasshopper sperm cell improvement, given conclusive insights that cell division in gametes was not simply customary mitosis. Sutton showed that the quantity of chromosomes was decreased in spermatozoan cell division, a cycle alluded to as reductive division. Because of this cycle, every gamete that Sutton noticed had one-a large portion of the hereditary data of the first cell.

Alguien dígame por favor cual es el proceso por el cual los seres vivos obtienen energía desde el punto de vista de la biología, necesito una respuesta compleja, gracias
Answer:
Explanation:
La degradación de carbohidratos, sobre todo de la glucosa, es la fuente principal de energía en la célula. La degradación oxidativa de la glucosa a CO₂ y H₂O produce una gran cantidad de energía libre, la cual puede almacenarse en la célula en compuestos ricos en energía como el ATP.
La glicólisis es la etapa principal en la degradación de la glucosa, la cual se oxida hasta piruvato. Ocurre en ausencia de oxígeno y por lo tal organismos anaerobios utilizan este mecanismo para obtener energía. Durante este proceso se obtienen 2 moléculas de ATP.
Luego, el piruvato se oxida para dar un acetilo, que se une a una Coenzima A dando acetil-CoA. Luego éste entra en el ciclo de Krebs, que es la vía central del metabolismo oxidativo. El acetilo se combina con oxalacetato para dar citrato. A través de ocho reacciones dos carbonos se oxidan completamente a CO₂ y se regenera el oxalacetato. Durante el ciclo se genera GTP, un compuesto con un enlace de alta energía. Además, cada vuelta del ciclo produce tres moléculas de NADH y una de FADH₂, que son transportadores de electrones.
Durante la fosforilación oxidativa, los electrones de estos transportadores se combinan con oxígeno y la energía liberada en el proceso promueve la síntesis de ATP.

The image below shows the process of DNA replication. Identify the components of the process.
Sorry I'm late, God bless!
The given diagram shows DNA replication in mammals. The labelled parts of DNA replication in this diagram are: DNA Polymerase, RNA primase, topoisomerase, Okazaki fragments, and DNA helicase.
What is DNA replication?DNA is the genetic material in human beings. The double-stranded DNA undergoes replication to divide and form daughter strands. The main enzymes required for the replication are: DNA Polymerase, RNA primase, topoisomerase, Okazaki fragments, and DNA helicase.
DNA Polymerase: It is responsible for the polymerization of new strands of DNA
RNA primase: The polymerase requires a primase for the proper attachment on the DNA strand to begin the replication process
Topoisomerase: This class of enzyme is responsible for introducing negative supercoils in the strands of DNA which will open up the DNA double strands
Okazaki fragments: The okazaki fragments are present in the lagging strand of DNA. These are the small fragments of DNA which is not synthesized continuously
DNA helicase: These enzymes are responsible for the separation of the double strands of the DNA molecule.

What happens to the rate of photosynthesis as the intensity of light or concentration of CO2 increases? And How is your conclusion from the question above different from what happens as temperature increases?
Answer:
The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.
Explanation:
Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.
An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
