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?

Answers

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.

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

Answers

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.

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.

Answers

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.

If a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, the substance will move by diffusion

What are diffusion and its importance?

Diffusion is the transfer of individual molecules of material from a region of higher concentration to a region of lower concentration over a semipermeable barrier

Cells depend on diffusion to get the nutrients they need to develop and obtain energy as well as to rid themselves of waste materials. It helps in gaseous exchange during respiration in organisms.

Thus, when a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, then the substance will move by diffusion

Explanation: Genes are encoded with different traits. Each of these traits carries different functions to the new offspring that is developing. ... The genes that an organism inherits can affect gene function. For example, they can have a recessive gene for something that might affect them. I hope that this helps you out, have a fantastic day!!

The factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.

What is the significance of the traits and their regulators?

Traits are determined by the combination of genetic and environmental factors, such as temperature, light, and nutrition, which affect the expression of genes and the development of an organism's traits, as exposure to certain pollutants leads to mutations in an organism's genetic material.

Hence, the factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.

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

Answers

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.

Explanation:

Their is 30% thymine and a total of 30% adenine, and there is 20% cytosine and 20% guanine.

Well in DNA the complimentary pairs are Adenine and Thymine, Cytosine and Guanine - Whatever Thymine has Adenine must have the exact same (So in this case Thymine has 30% this must mean Adenine also has 30%) so if there is 40% remaining this must be split between the pair Cytosine and Guanine which would give 20% each

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).
