Answer: C: Se inhibe (no se desarrolla) la ovulación.
Explanation:
Los métodos anticonceptivos se utilizan prevenir el embarazo no deseado, evitando que el esperma fertilice a un óvulo. Hay distintos tipos, los cuales se clasifican en:
Anticonceptivos hormonales: Contienen hormonas, tales como estrógeno y progesterona, que previenen la ovulación (es decir, la liberación de óvulos de los ovarios). De esta manera, al no haber óvulo disponible, por mas que hayan espermatozoides, no va a ocurrir ninguna fecundación. El método mas conocido es la píldora o pastilla anticonceptiva. Anticonceptivos de barrera: Proveen una barrera física que impide la fecundación al impedir el encuentro entre el óvulo y el espermatozoide. Por ejemplo, el uso de preservativos o condones. En estos métodos, se impide la entrada de los espermatozoides, no se encuentran con el óvulo y la esperma queda atrapada dentro del condón. Anticonceptivos permanentes: Proveen un método permanente como por ejemplo el Dispositivo Intrauterino que se coloca en el tracto uterino con una vida media de meses o años y posee un efecto espermicida que mata a los espermatozoides (por lo que no lograrán encontrar un óvulo). Otro ejemplo es la vasectomía, la cual es una cirugía que corta los conductos deferentes que transportan a los espermatozoides por lo que ya no pueden salir de los testículos para producir la fecundación (quedan atrapados dentro de los testículos, no entran al tracto uterino y no encuentran al óvulo)Tanto los métodos de barrera como los permanentes, no inhiben la ovulación aunque si impiden que el óvulo se encuentre con el espermatozoide. Entonces, los métodos hormonales son los únicos que logran inhibir la ovulación. Las píldoras que poseen las hormonas previamente mencionadas pero fabricadas sintéticamente. Las mismas mimetizan el efecto de las hormonas naturales producidas por el cuerpo, alterando el ciclo menstrual regular y así evitan el embarazo ya que no habrá óvulo disponible para fecundar. Además, también pueden alterarla mucosidad en el cuello del útero para que los espermatozoides no pueden atravesarlo y llegar al óvulo. De todas maneras, el objetivo principal y mas importante de los métodos hormonales es bloquear la ovulación.

All else being equal, as compared to an organism with a lower surface-area-to-volume ratio, an organism with a higher surface-area-to-volume ratio would likely have less difficulty maintaining a constant internal environment. lose more heat to the environment in cold environments. have greater thermal inertia. lose less heat to the environment in cold environments.
Answer:
lose more heat to the environment in cold environments
Explanation:
This is because as an animal have large surface area, it is exposed largely and prone to loss of heat. The larger the size of an animal, the larger the surface area and volume. It's surface area expose the tendency for the animal to sweat alot , through sweating heat is loss to the environment. In cold environment, the animal try to maintain internal homeostasis and through this heat is generated and loss to the environment.

Wolves are predators of deer. What is most likely to happen to the deer population if the wolf population increased? 0 stay the same increase decrease Obecome extinct
Since wolves are indeed the main predator of deer, if wolves were to increase in their population, the population of the deer will inevitably decrease dramatically.
Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time, and good luck finding the correct answer :)
If the wolf population were to increase, it is most likely that the deer population would decrease.
What is predator?A predator is an organism that hunts and consumes another (the prey). This is known as predation.
Predators, in general, share the following characteristics: They are usually larger than their prey or, like ants, overwhelm them by attacking in large numbers.
If the wolf population increases, the deer population will most likely decrease.
This is because wolves are deer predators, and an increase in the number of wolves means more deer will be hunted and killed by wolves.
The deer population is unlikely to become extinct as a result of an increase in the wolf population because other factors such as disease, habitat loss, or human hunting can also have an impact on the deer population.
Thus, the population will decrease.

A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these explanations BEST describes this observation?
a. The herbicide company lost its formula and started selling poor-quality herbicide.
b. Natural selection caused pigweed to mutate, creating a new triazine-resistant species
c. Triazine-resistant pigweed is more efficient at photosynthesis.
d. More triazine-resistant individuals survived each year, soi more individuals were triazine-resistant.
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Answer:
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Explanation:
The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.
Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.
Resistance to the toxic is associated with mutations in some of the genes.
A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
The selective pressure or modeling environmental factor is the triazine herbicide The weed´s response to herbicide is the survival of only those that carry mutations. Natural selection benefits these mutations. The mutated herbs survive, become more resistant, and pass the mutation to their offspring.A relationship in which one species kills and consumes another species is known as

In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.
Answer:
If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes
Explanation:
Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.
can anyone tell me hypothesis for eye disease...
Answer:
Mostly radiations or dangerous products that come in contact with the eye For example, maybe harmful makeup product but there are many reasons for eye disease, you should elaborate more on dangerous product put on skin and harmful chemical
Explanation:
The pathophysiology of primary open-angle glaucoma is still largely unknown, although a joint contribution of vascular, biomechanical, and biochemical factors is widely acknowledged. Since glaucoma is a leading cause of irreversible blindness worldwide, exploring its underlying pathophysiological mechanisms is extremely important and challenging. Evidence from recent studies appears supportive of the hypothesis that a “glymphatic system” exists in the eye and optic nerve, analogous to the described “glymphatic system” in the brain. As discussed in the present paper, elucidation of a glymphatic clearance pathway in the eye could provide a new unifying hypothesis of glaucoma that can incorporate many aspects of the vascular, biomechanical, and biochemical theories of the disease. It should be stressed, however, that the few research data currently available cannot be considered as proof of the existence of an “ocular glymphatic system” and that much more studies are needed to validate this possibility. Even though nothing conclusive can yet be said, the recent reports suggesting a paravascular transport system in the eye and optic nerve are encouraging and, if confirmed, may offer new perspectives for the development of novel diagnostic and therapeutic strategies for this devastating disorder.
