Why is drinking water usually treated before it comes out of your faucet?
Answer:
For public health and safety, water is treated before it reaches your faucet. Water treatment involves the removal of impurities that make water unsafe for human consumption. This water may flow from a surface water source, or it may be pumped from an aquifer. Hope this helps!!!

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.
Which of the following is a reactant in photosynthesis?
a. O2
b. C6H12O6
c. COOH
d.CO2

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.

This model shows a human embryo. What can you determine about its development from the model?
It has a postanal tail.
It’s a vertebrate
It has pharyngeal arches.
It has fully developed organ systems.
In humans, tails are vestigial structures, meaning the embryo can express it in early stages of development, but then, they loose it. Option A) It has a postanal tail.
What is a vestigial structure?Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species.
These vestigial structures might be found in many animals, including human beings. They were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.
An example of these structures is the coccyx. This tailbone is the remnant of a missing tail. Actually, all mammals have a tail at some point in their development, even in humans, it is present for a period of 4 weeks during embryogenesis, but after a period of time this tail disappears and its forming vertebras get fussed with each other composing the coccyx.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function. Although it is still an area of muscle insertion.
The correct option is A) It has a postanal tail.

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.
Biomes all share the same biotic and abiotic factors other than annual precipitation levels.

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 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.

Where do you get a Genetic Disease such as DMD?
Answer:
DMD is inherited in an X-linked pattern because the gene that can carry a DMD-causing mutation is on the X chromosome. Every boy inherits an X chromosome from his mother and a Y chromosome from his father, which is what makes him male. Girls get two X chromosomes, one from each parent.
