Which of the following best explains why top predators can have up to 60 times as much of persistent organic pollutant (POP) as their prey and up to 600 times as much of the pollutant as producers?
A. POPs accumulate in the body fat of living organisms. POPs increase in concentration as they move up the food chain.
B. POPs can travel over long distances by wind or water. Predators have greater access to different locations than do producers and therefore have higher concentration of POPs
C. POPs are not carbon-based compounds so animal digestive systems lack enzymes capable of breaking them down. POPs biomagnify in the fatty tissues of animals but not in plants.
D. POPs are solids, which only animals can ingest. Therefore, POPs have a greater effect on secondary and tertiary levels of food chains

El sistema respiratorio tiene una función vital en la supervivencia de los seres humanos y otros organismos. Es responsable de tomar oxígeno del ambiente y exhalar dióxido de carbono y otros gases de desecho.

Los principales gases que utiliza el sistema respiratorio para llevar a cabo su función son el oxígeno y el dióxido de carbono.El oxígeno es un gas vital para el cuerpo humano y es utilizado por las células del cuerpo para producir energía a través del proceso de respiración celular.

El oxígeno entra en el cuerpo a través de la inhalación y se une a la hemoglobina en los glóbulos rojos en el sistema circulatorio para ser transportado a las células del cuerpo. Una vez que el oxígeno es utilizado por las células, se convierte en dióxido de carbono y se transporta de regreso al sistema respiratorio.El dióxido de carbono es un gas de desecho producido por el cuerpo humano durante el proceso de respiración celular.

El dióxido de carbono se une a la hemoglobina en los glóbulos rojos y se transporta de regreso al sistema respiratorio para ser exhalado del cuerpo. La eliminación adecuada del dióxido de carbono del cuerpo es esencial para mantener un equilibrio ácido-base saludable.

En resumen, el sistema respiratorio utiliza principalmente oxígeno y dióxido de carbono para llevar a cabo su función vital en el cuerpo humano y otros organismos.

➜ Release of CO2 and intake of O2 gives evidence that either photosynthesis is not taking place or its rate is too low. Normally during day time, the rate of photosynthesis is much more than the rate of respiration. So, CO2 produced during respiration is used up for photosynthesis hence CO2 is not released.

Alterations in DNA sequences or mutations can result in changes to the protein-coding sequences, regulatory regions, or non-coding regions of the DNA.

Alterations in DNA sequences, such as mutations, can contribute to variation that can be subject to natural selection.

These alterations in DNA sequences can contribute to genetic variation within a population. If the mutation provides an advantage in a particular environment, individuals with that mutation may have greater survival and reproductive success than those without it.

Conversely, if the mutation is deleterious, individuals with the mutation may have reduced survival and reproductive success, and natural selection may favor the elimination of the mutation from the population.

It could also share the same genus as white sharks. A genus is a category of biological classification ranking between family and species.

Option b is correct.

The first name given to a species is its genus name. Animals or plants that belong to the same genus have a number of characteristics in common. Each genus is made up of one or more species.What is Elasmobranchii?Sharks, rays, and skates belong to the Elasmobranchii class. Their skeletons are made up of cartilage instead of bone, they have several rows of teeth, and they breathe through five to seven gill slits on the sides of their heads.

Spotted Eagle Ray and White Sharks are part of the Elasmobranchii class. This does not, however, imply that they belong to the same genus. When two organisms share the same class, it indicates that they have several traits in common, such as having a skeleton made of cartilage and five to seven gill slits on the sides of their heads.

True, respiration can be classified as active and passive

Forced breathing is an active mode of breathing which utilises additional muscles to rapidly expand and contract the thoracic cavity volume. It most commonly occurs during exercise.

The process of normal expiration is passive, meaning that energy is not required to push air out of the lungs. Instead, the elasticity of the lung tissue causes the lung to recoil, as the diaphragm and intercostal muscles relax following inspiration.

After a natural disturbance causes mortality in a population, there is a change in the population's gene pool. this is known as a Bottleneck Effect.

Bottleneck Effect- The bottleneck effect is a phenomena that occurs when a population's gene pool suddenly shrinks as a result of a natural environmental occurrence, a natural disaster, a disease, or human activity. A bias that wasn't there in the initial population will probably result from this shrinkage of the gene pool.

Gene Pool- A gene pool is the collection of all the alleles (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.

The first stage of sleep is defined as the period between wakefulness and sleep, and it is characterized by a decrease in brain activity and muscle tone.

The body's typical state during the first stage of sleep includes a decrease in muscle tone, a slowing of brain waves, and a decrease in eye movement. During this stage, the brain waves are generally alpha waves, which are slower than those that occur during wakefulness, but faster than those that occur during deeper stages of sleep.The first stage of sleep is often referred to as light sleep because it is easy to be awakened from this stage.

It usually lasts for about 5-10 minutes, and during this time, the body's temperature begins to decrease, and the heart rate and breathing rate begin to slow down. In addition to these changes, the body may also experience other physiological changes, such as a decrease in blood pressure and a decrease in the production of stress hormones.

The first stage of sleep is an important part of the sleep cycle because it is the stage that helps to prepare the body for deeper stages of sleep. During this stage, the body begins to relax, and the mind begins to slow down. This allows the body to enter deeper stages of sleep, where the brain waves slow down even further, and the body's muscles become even more relaxed. Overall, the first stage of sleep is an important part of the sleep cycle, and it is necessary for the body to enter deeper stages of sleep so that it can rest and rejuvenate.

Evolution means change in the physical features of an organism.

Explanation:

Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

Answer:The phospholipids are arranged in a bilayer with the hydrophobic tails facing inward. The tails are packed tightly together, thus preventing any large molecules from diffusing through.

Explanation:

The better the temperature, the greater kinetic electricity the debris will have, so they'll circulate and blend greater quickly. The extra the floor area, the quicker the price of diffusion.

If a crystal of a colored chemical, eg potassium manganate(VII), is located in water, the debris unfold out and blend with the water debris.The debris have moved from a location of excessive attention withinside the crystal to a low attention withinside the water. This distinction in attention is referred to as a attention gradient.
