Answer:
The best example of this is ‘Pavlov’s dog’; classical conditioning is sometimes referred to as Pavlovian conditioning.
A honey bee's proboscis extension reflex - the bee extends its proboscis as a reflex to antennal stimulation.
Answer:
Examples of associative learning include: If someone puts their hand on a hot stove and hurts themselves, they may learn to associate hot stoves with pain, and have therefore been conditioned not to put their hands on them.

The Endangered Species Act was passed in 1973, but many people today feel that the Endangered Species Act has not done enough to protect endangered species from human impacts. do you think that it needs to be updated? Give specific examples why or why not.
Answer:
Absolutely
Explanation:
only 3 percent of species protected by the law have recovered to the point where they are no longer threatened or endangered. The ESA can and should be strengthened so that it not only continues to protect species, but also promotes their full recovery.
In the last 100 years we human beings have eliminated 10 times more species than have disappeared in the past at the natural background rate. Without conservation, we are at risk of losing precious wildlife and depriving future generations of America’s heritage.
With the growing menace of climate change, many more species need our protection. In 1973, there were only 78 species listed in the ESA; now there are almost 1,600.
Can snow form with a warm and cold front
Answer:
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.

What are the effect of silt on aquatic organisms?Silt refers to small fine particles of sand or mud that forms a suspension in water.
Silt in oceans usually come from rivers opening into the sea
The silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea will originate from rivers and streams opening into the sea.
The silt will reduce the population of algae on the coral reef as they increase water turbidity.
This will reduce fish population in the area and the food source for humans.
Industrial wastes are a source of mercury in lakes.
The presence of mercury will poison the lake and kill the fishes in the lake.
It will also make the water unfit for drinking by humans.
Therefore, pollution of water bodies kills aquatic organisms and this disrupts food source for humans.

It’s multiple-choice I just need the answers please
Answer:
2, 2, 1, 2, 4
Explanation:
Question 1. - Decomposers break apart dead organisms into simpler inorganic materials, making nutrients available to the plants/primary producers.
Question 2. - Energy decreases as it moves up trophic levels because the energy is lost as metabolic heat when the organisms are consumed by other ones from the next level.
Question 3. - Energy moves through an ecosystem in a single direction from the sun to autotrophs/producers, then from producers to heterotrophs/consumers. Never backward from consumers to producers.
Sun ⇒ Producers ⇒ Consumers ⇒ Decomposers
Question 4. - See Question 1.
Question 5. - Autotrophs don't need energy from other organisms. Instead, they use photosynthesis to get their food.
- Note: Fungi cannot make their own food and therefore are not autotrophic. They do not have chloroplasts, instead, they are osmotrophic!

HUMAN EGGS AND SPERM EACH CONTAIN 23 _____, WHICH ARE COMPOSED OF LONG STRANDS OF _________.
Explanation:
HUMAN EGGS AND SPERM EACH CONTAIN 23 "Chromosomes"WHICH ARE COMPOSED OF LONG STRANDS OF "DNA"
Human eggs and sperm each contain 23 chromosomes, which are composed of long strands of DNA.
What are Chromosomes?Chromosomes may be defined as the thin, thread-like structure that appears during cell division. Chromosomes are generally found in the nucleus of the cell in the form of thread. These thread-like structures are made up of DNA, RNA, histones, and non-histone proteins.
The Chromosome was first discovered by E. Strasburger in 1875. But the term chromosome was given by Waldeyer in 1888.
Almost all the cells of the human body have 46 chromosomes. But there are two types of cells that are structurally and functionally different. These are known as the egg cells which are present in females and the sperm cells which are present in males.
Both these cell types in humans only have 23 chromosomes instead of 46. These chromosomes are remarkably composed of long and double strands of DNA.
Therefore, human eggs and sperm each contain 23 chromosomes, which are composed of long strands of DNA.
