An example of parasitism is a tick on a dog. Therefore the correct option is option B.

In an ecological connection known as parasitism, one creature (the parasite) gains advantages at the expense of the other organism. (the host).

When a tick bites a dog, the dog suffers negative consequences such skin rashes, anemia, and possible disease transmission while the tick receives the nutrients it needs to survive and reproduce from the dog's blood.

As both animals gain from the relationship, bees and flowers are an example of mutualism. Bees obtain nectar from flowers and use it to pollinate them. Therefore the correct option is option B.

The types of natural selection in biology are: Stabilizing selection, Directional selection, Disruptive selection, and Sexual selection.

Natural selection is the process by which certain traits become more or less common in a population over time, based on how well those traits enable the individuals who possess them to survive and reproduce.

1. Stabilizing selection: This occurs when traits that fall within a certain range are favored, while those that deviate from that range are selected against. This leads to the stabilization of a trait within a population.

2. Directional selection: This occurs when a certain trait becomes more or less favorable, causing the population to shift in that direction. This leads to a change in the average value of a trait within a population.

3. Disruptive selection: This occurs when traits at both extremes of a range are favored over those in the middle. This can lead to the splitting of a population into two distinct subpopulations, each with their own favored trait.

4. Sexual selection: This occurs when certain traits are favored because they increase an individual's ability to attract a mate. This type of selection can lead to the evolution of exaggerated or flashy traits, like the colorful plumage of a peacock.

Answer:

Yes

Explanation:

Because the plant has micro bacterial to live off of. Not all plants need sunlight.

Phytoplankton and bacteria would be the most affected by dead zones. Dead zones are areas in bodies of water, typically in the ocean, where oxygen levels are extremely low or depleted.

Option (a) is correct.

These low oxygen conditions are primarily caused by excessive nutrient pollution, often from human activities such as agricultural runoff and sewage discharge. Phytoplankton are microscopic plants that are the foundation of the marine food chain. They require oxygen to survive and play a crucial role in producing oxygen through photosynthesis. In dead zones, the lack of oxygen prevents phytoplankton from thriving, leading to a decline in their population and disrupting the entire food chain.

Bacteria are also affected by dead zones as they play a vital role in decomposing organic matter in the water. When oxygen levels are low, bacteria that require oxygen for their metabolic processes struggle to survive, which can further exacerbate the depletion of oxygen in the area.

However, the primary impact in dead zones is typically observed in the lower levels of the marine food chain, affecting organisms like phytoplankton and bacteria.

Therefore, the correct option is (a).

Developed countries need to replace modern medicines with natural healing herbs because millions of people in China and India are already doing so. This is an example of a(n) bandwagon argument.

The statement "Citizens must support reducing global climate change or all the world's major economies will crash" is an example of a false dichotomy argument. A false dichotomy is a logical fallacy that presents two options as if they were the only ones possible, when in reality there are more alternatives. It can be seen in the above-mentioned statement as it presents only two choices, either citizens must support reducing global climate change, or the world's major economies will crash.

However, there could be other alternatives or solutions to this problem that are not being considered. In contrast, the argument "Developed countries need to replace modern medicines with natural healing herbs because millions of people in China and India are already doing so" is an example of a bandwagon argument.

 A bandwagon argument is a type of logical fallacy that suggests that something is correct or right because a lot of people are doing it.

As  per the formula to calculate the speed, it is calculated by the distance and time. The point where the distance is almost  same shows the snail stopped moving.

It is a scalar quantity. The relationship between speed and distance can be expressed by the equation:

Speed = Distance/Time

In another terms , speed is rate at which any  object moves through  the space, and is totally  calculated by  just dividing the distance  that is covered by the time taken to almost  cover the distance.

The greater the distance traveled in a given amount of time, the faster the speed of the object, while a smaller distance traveled in the same amount of time would result in a slower speed.

Therefore, speed of any  object is  almost directly proportional to the distance traveled and is  inversely proportional to time taken to travel distance. The snail is constant as it is not changing any distance.

Answer:

1. Offspring survive chances.

2. chance of survival of the organisms

3. Increase the odds of a spontaneous variation

Explanation:

1.While external fertilization is not further divided into any further types. The advantages of internal fertilization are, offspring survival chances are enhanced within the safe environment inside the body of the mother. Chances of successful fertilization are also enhanced.

2. The main advantage of genetic variation is that it increases the chance of survival of the organisms. The nature always selects the fittest organism. So if there was no variation in genetic make up of the organisms, there would not have been so many species of the organisms living in this world.

3.When more offspring are produced, it increases the odds of a spontaneous variation. A variation could be a genetic advantage, such as a bird with brighter colors who is able to attract more and better mates. Over time, multiple variations could lead to the creation of a new species altogether.

During development, the epithelial structures that make up endocrine glands lost contact with the surface. The ductless nature of these glands explains why they produce secretions.

The parenchyma of the thyroid, parathyroid, anterior pituitary (adenohypophysis), adrenal cortex, pancreatic islets, and liver are all made up of epithelial tissue. The epithelial idea of these phones is reflected in their association into lines or bunches, with cells connected along the side to adjoining cells as in surface epithelium.

While exocrine glands have ducts, endocrine glands do not have ducts, so their secretions flow directly into the blood. Endocrine glands are characterized by the following features: They lack ducts, are highly vascularized, and contain hormone-storing intracellular vacuoles or granules.
