Answer:
- Evidencia: registro fósil
- Función: capacidad de distinguir depredadores
Explanation:
Un ojo compuesto es una órgano sensorial altamente especializado compuesto por unas estructuras conocidas como omatidios, las cuales están a su vez compuestas por células fotorreceptoras. La superficie externa de un omatidio es una lente hexagonal, debajo de la cual se encuentra una lente cónica capaz de captar la onda lumínica. La evidencia más importante de animales con ojos complejos que habitaron el planeta hace millones de años fue el descubrimiento de un ojo fosilizado en un crustáceo (aprox. 515 millones de años atrás). El ojo de este animal estaba compuesto por miles de lentes. Interesantemente, las lentes del centro del ojo compuesto se destacaban por su mayor sensibilidad, lo cual se cree le conferían a este crustáceo la habilidad de distinguir mejor estructuras y formas en ambientes oscuros. En consecuencia, este descubrimiento soporta la idea de la evolución temprana de la vista como una característica fundamental que le habría conferido a una especie de crustáceo la posibilidad de distinguir fácilmente a sus depredadores.

An animal jaw that has small incisors and canines but wide premolars and molars may belong to a _____. a. beaver c. horse b. dolphin d. wolf
There is less need for canines and incisors in herbivorous animals as it is mainly used to tear the flesh. Herbivorous animals mainly have developed premolars and molars to grind the grass properly. Horse has small incisors and canines but wide premolars and molars.
What are the different types of teeth?Teeth are usually covered with a hard substance called enamel which helps them to be strong. Its color is slightly yellow.
Teeth are of four types. Namely:
Incisor: These are located at the front and are used to cut the food.Canine: These are at the sides of incisors and are generally used for tearing the flesh. pre-molars: These are present near the corner of the jaw before molars and are used to grind.Molars: these are at the corner of the jaw and are also used for grinding food.Canines are well developed in carnivorous animals as they need to tear the flesh. But in the case of herbivores, these are comparatively smaller.
Thus, an animal jaw that has small incisors and canines but wide premolars and molars may belong to a horse.

Is human development best characterized as a slow, gradual process, or is it best viewed as one of more abrupt change?
Answer:
Heyya!
Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life. When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.
The human development is best characterized as the gradual change.
What is human development?Human development is explained as the method of increasing people's liberties and opportunities while also improving their well-being.
Human development is about the genuine freedom that ordinary people have to choose who they are, what they do, and how they live.
Cognitive theory is concerned with how a person's thought processes develop.
It also investigates how these thought processes affect how we perceive and interact with the world. One of the most influential theories of cognitive development was proposed by theorist Jean Piaget.
According to proponents of the continuity viewpoint, development is a continuous, gradual, and cumulative process. A child, for example, learns to crawl, then stand, and finally walk. They are slowly learning to walk.
Thus, the human development process is gradual.

explain how the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population
Answer:
Seaweed might start to grow out of control withough crabs eating it, octopuses on the other hand would struggle to find food and start to die off because they relie on crabs to be their food source.
Without crabs to consume it, seaweed would start to grow out of control; octopuses, on the other hand, might struggle to find food and begin to disappear because they depend on crabs as a food supply.
What is the role of seaweed and octopus in ecosystem?
Seaweeds are important components of marine ecosystems. They serve as the primary source of nutrients and energy for marine organisms.
Either directly when fronds are consumed or indirectly when decomposing sections break down into small particles that are ingested by filter-feeding species.
No other creature has a predatory function as significant as that played by octopuses in forming communities.
Therefore, the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population.

A.
Use of the GAH may increase the availability of milk.
B.
Use of the GAH may increase the amount of hormones in the milk.
C.
Use of the GAH may provide extra milk to feed the poor.
D.
Use of the GAH may allow the farmer to reduce milk prices.
Answer:
B
Explanation:
A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
What is a genetically altered hormone(GAH)?The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.
Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
