Hyenas usually hunt for food alone, but some scientists discovered that
hyenas will sometimes hunt with a pack of wolves. The hyenas benefit from
being able to catch more food with a pack. The wolves benefit from the
hyenas' ability to break through bones and excellent sense of smell.
Which type of relationship is this an example of? Explain.
This is an example of mutualism, which is a type of symbiotic relationship in which both species benefit from the interaction.
What is mutualism?An example of a symbiotic relationship between two species is mutualism, in which both species gain from the association. Each organism in a mutualistic interaction offers the other a resource or service that is mutually beneficial. In nature, this kind of connection is frequently observed, for instance, between pollinators and the flowers they pollinate.
In this instance, hunting with wolves and hyenas is advantageous. The wolves assist the hyenas in capturing more prey, and the hyenas benefit from the wolves' superior sense of smell and capacity to break through bone.

what is one way the vision of primates is different from that of other animals? group of answer choices primates have monochromatic vision. primates have open eye orbits not enclosed by bone. primates have overlapping vision fields. primates have eyes on the side of the head.
Primates have overlapping vision fields; this is way the vision of primates is different from that of other animals.
Any mammal belonging to the group that includes lemurs, lorises, tarsiers, monkeys, apes, and humans is referred to as a primate in zoology. After rodents (Rodentia) and bats, the order Primates has more than 500 species and is the third most varied group of mammals (Chiroptera).
The low, rounded morphology of the molar and premolar cusps, which contrasts with the high, pointed cusps or complex ridges of other placental animals, makes primate teeth distinct from those of other mammals. The difference makes it simple to identify fossilized primate teeth.

Which of the following is a consequence of free riders?.
The consequence of free riders is that they allow others to bear the burden of the public good while reaping its benefits without contributing. Free riders refer to individuals who do not contribute to a public good but benefit from it.
For example, an individual may choose not to pay their fair share of taxes that go towards public education but still benefit from having an educated population. The consequence of free riders is that they allow others to bear the burden of the public good while reaping its benefits without contributing.
In other words, free riders can lead to a tragedy of the commons where a shared resource becomes overused and depleted due to people taking more than their fair share without contributing to its upkeep. This can result in the destruction of the public good, which is a negative consequence for everyone. Therefore, it is essential to prevent free riding to ensure the sustainability of public goods.

benefits of variation in height
Answer:
It’s nice to be tall. Tall people are more likely to get hired, get promoted and are paid better than their shorter counterparts. They can reach things from high shelves, have unobstructed views at parades, and are consistently rated as being more attractive than others. Overall seems like a sweet deal.
If you are short, you get depressed when some points out that a study in the New England Journal of Medicine suggested that shorter people are at higher risk for heart disease. However, you might find some solace from a study published in PLOS one that found that shorter people lived longer or another study that suggested that taller people are at increased risk for cancer. When it comes to whether it is better to be tall or short, there is a lot of medical research on the subject, and one half contradicts the other half.
These studies get a lot of media play because they are instinctively popular. We are obsessed with height as a society. After all, we invented high-heeled shoes to defy genetics and punish our ankles.
But every time a report claims that taller is better (or that shorter is better), headline writers seem to consistently forget that six months ago they were claiming the opposite.
But being short i also nice so if someone is making fun for your height its because their insecure about their own height
Answer:
Variation in height creates a diverse and more dynamic world, we need certain heights for certain careers as well as certain tasks.

Sarah learned that the steps of transcription and translation are similar to baking a cake from a recipe. The cell's genome is like a cookbook, with step-by-step directions. The mRNA copy is like writing down a copy of the instructions to give to someone else. What would the amino acids be most similar to?
The amino acids would be most similar to the ingredients used in the recipe.
When the mRNA moves out of the nucleus, it then gives the instructions (the genetic sequence) to someone else, which is tRNA. During translation, the tRNA and mRNA complex reads the genetic sequence and then binds required amino acids, sequentially. Thus, the combined amino acid chain forms the desired protein.
Therefore, the amino acids are the ingredients and the protein is the final dish.

Bile carries out ______ A. Chemical digestion B. Mechanical digestion C. Enzymatic digestion D. Both chemical and mechanical digestion
Bile carries out both chemical and mechanical digestion. Therefore, the correct answer is option (A) and (B). Bile is a substance produced by the liver and stored in the gallbladder before being released into the small intestine.
It plays a crucial role in the digestion and absorption of dietary fats. Bile aids in mechanical digestion by emulsifying fats. Emulsification is the process of breaking down large fat droplets into smaller droplets, increasing their surface area and allowing enzymes to access them more effectively. This mechanical action of bile helps to physically break down fats into smaller particles, facilitating their subsequent digestion and absorption. Hence, options (A) and (B) are the correct answer.
Bile also contributes to chemical digestion. It contains bile salts, which are amphipathic molecules that interact with fat molecules. Bile salts aid in the digestion and absorption of fats by forming micelles. These micelles solubilize and transport fat molecules, allowing pancreatic lipases to break them down into fatty acids and glycerol, which can then be absorbed by the small intestine.

Outline THREE adaptations of terrestrial plants for their survival in their habitat.
Answer:
Stomata for gas exchange, water resistant waxy cuticles on leaves and specialized cells for support.
Explanation:
Plants have undergone several modifications for life on land. These include the development of several mechanisms:
a waxy, thick water-repellent cuticle- the thick cuticle provides a barrier to water loss from plant tissues in the leaf. stomata- these moderate the evaporation of water, an important commodity to land dwelling terrestrial organisms. They also regulate gas change cells to provide strength and rigidity- plant cells are specialized cells that contain lignin and cellulose, these are rigid provide good support against gravitational forces, Without them the stem would break and the cells would readily lose waterdue to various causes, including ddt poisoning, the population size of whooping cranes was reduced to about a dozen during the 1970s. the population size has since rebounded, and there are now hundreds of whooping cranes. which feature would not be expected in the current populations of whooping cranes?
Due to various causes, including DDT poisoning, the population size of whooping cranes was reduced to about a dozen during the 1970s.
The population size has since rebounded, and there are now hundreds of whooping cranes. The feature that would not be expected in the current populations of whooping cranes is: DDT contamination in their bodies.The recovery of whooping cranes was due to the United States and Canada's joint efforts in the conservation and restoration of their population size. It is through the Endangered Species Act that their population has increased, and the North American conservation community's efforts to protect them has also played a role in this. These efforts have allowed the population to grow, and whooping cranes are now no longer on the brink of extinction.
However, due to the fact that whooping cranes have a long lifespan, and their habitat is contaminated by DDT and other contaminants, they continue to face challenges in their survival. As a result, the feature that would not be expected in the current populations of whooping cranes is DDT contamination in their bodies. The DDT contamination in their bodies is a residue from the 1940s and 1950s. DDT was commonly used as a pesticide in the United States until it was banned in 1972 due to its harmful effects on the environment and wildlife.
