Answer:
The arrow should be pointing from the producer towards the consumer.
Producer --> Consumer
Explanation:
The arrow represents the flow of energy in a food web. Producers are the first source of energy, as they make their own food. The energy is then transferred to the consumer when they eat the producer. For example, if a cow were to eat grass, the energy would flow from the grass to the cow. The arrow shows how this energy is flowing from the first source to the second.
Answer:
In addition to the local control of blood flow, global control of blood flow including changes in cardiac output and control of arterial BP is mediated by the autonomic nervous system. Global neural control of arterial hypertension is essentially through the sympathetic nervous system (SNS).

From Google
The slide of stages in starfish development illustrates stages from unfertilized egg to gastrula—typical of echinoderms and chordates that have very little yolk in the egg. Three embryonic cell layers—ectoderm, endoderm, and mesoderm—are established. All adult tissues are derived from these layers.
The structure (shape and number) of an animal’s teeth vary according to what food they consume.
For example, molars- flat teeth at the back of the mouth are very different among different types of animals:
• Herbivores (eat plants) have strong and flat molars ,
• Carnivores (eat meat) have limited number of molars,
• Omnivores (eat combine food) have molars for grinding.
On the other hand canine teeth are small or sometimes don’t even exist in herbivores are very defined and sharp in carnivores.
