Actually there are 4 types of predation: carnivory, herbivory, parasitism, and mutualism.

<span>CarnivoryCarnivorous predators kill and eat their prey. The common perception of carnivory involves a large animal, such as a lion or a tiger, hunting smaller animals like rabbits or deer. However, carnivorous predation is widespread in the animal world and carnivores can come in a variety of sizes – from sea otters hunting sea stars to blue whales consuming zooplankton, each carnivore is adapted to its mode of feeding. One exceptional and unusual example is cannibalism.
HerbivoryHerbivorous predation involves the consumption of autotrophs, such as plants or photosynthetic algae. Unlike carnivory, not every herbivorous interaction leads to the death of the plant. Occasionally, herbivory can benefit the plant as well. Fruit seeds are dispersed over wide areas as the herbivore moves. Tough seed coatings are removed in the digestive tract of the herbivore, and its dung fertilizes the soil, providing an ideal environment for seed germination. <span>Grazing is an example and a form of herbivory where the plant regenerates the parts that were eaten by the herbivore</span></span><span>
ParasitismParasitism is a form of predation where the host supplies essential nutrients for the sustained survival and reproduction of the parasite. In many successful parasitic interactions, the host suffers a loss of energy, falls sick or loses access to nutrients. However, unlike carnivory, the host is not always killed. In most cases, the parasite is much smaller than the host. One example is tapeworms. Tapeworms are common human parasites that can cause malnutrition, especially in young children.</span><span>

MutualismMutualism involves the interaction between two organisms where the host provides the nutrition and space for the growth and reproduction of another species. However, the host is not harmed and the interaction is mutually beneficial. <span>The interaction between humans and their gut flora is a classic case of mutualism. The bacteria aid in digestion and provide protection against the invasion of pathogenic bacteria. Recent research suggests that the collection of all gut bacteria in an individual can have widespread impact on the host’s metabolism, immunity and well-being.

There are four commonly recognized types of predation: (1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism. Each type of predation can by categorized based on whether or not it results in the death of the prey. ... Mutualism is not lethal to either predator or prey but, rather, benefits both organisms.

A contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut is known
Romashka [77]

Answer:

Bronchospasm

Explanation:

Bronchospasm is known to be a condition that results from the contraction of the muscles that is found in the wall of the bronchioles which result into obstruction and narrowing of the respiratory airway. Thus, substance released from basophils or mast cell under the control of anaphylatoxin usually causes Bronchospasm. Furthermore, Bronchospasm is commonly caused by asthma and can also be caused by allergic reactions, respiratory infection, and chronic lung diseases.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend
anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings  will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

During the transmission of signals across a neuromuscular junction, which of the following happens first?
Gre4nikov [31]

Answer:

The correct answer is A acetylcholine binds to a receptor protein on the motor end plate

Explanation:

The neurotransmitter acetylcholine is released by the motor neuron during the transmission of signals across a neuromuscular junction.

         The released acetylcholine then diffuses the synaptic cleft and binds to the receptor protein present on the membrane of muscle fibre.

         This ultimately result in the influx of sodium ion inside the muscle cell thereby causing depolarization to generate an action potential.

galina1969 [7]

Answer:

<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>

Explanation:

Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.

On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
