A graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.
What are salinity and conductivity measurements?Salinity is a measure of the salt content of a water body.
Conductivity is a measure of the electrical conductivity of a solution or substance.
Conductivity increases with increase in salinity.
An estuary is a region where salt water from the sea meet freshwater from a river or stream.
At an upper estuary site where farmers use the water for irrigation, there will be decreased salinity and conductivity with time, while at a lower estuary site where there is a bream and flathead fishing industry, their will be increased salinity and conductivity with time.
Therefore, a graph over time of salinity and conductivity at an upper estuary site will be less inclined than that at a lower estuary site.

Describe and account for the relationship between the two population growth curves between hares and lynx.
Answer:
The lynx's principal food source is the snowshoe hare. These two species' population cycles are intertwined. When hares are abundant, lynx consume almost nothing else and kill two hares every three days. When hares are sparse, lynx eat mice, voles, squirrels, grouse, ptarmigan, and carrion.
1. Explain why testosterone can improve performance in sport.
2. Describe the role of oestrogen in the menstrual cycle.
Answer:
1How does testosterone enhance performance? Testosterone acts on muscle cells by binding to a specific receptor protein, the androgen receptor. Upon testosterone binding, the androgen receptor signals to the muscle cell to activate the pathways that trigger an increase in muscle mass, called muscle hypertrophy.
2The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH. When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle).
this is a simple diagram of a food chain:
producers --> herbivores --> carnivores --> top carnivores
if all the carnivores die out, why does the number of producers decrease?
i'm not sure but what im thinking is, well if carnivores die, then not many herbivores will die, therefore there isn't that natural soil fertilizer due to the dead bodies.
Explanation:
By all the carnivores, I assume it means regular and top carnivores. This will let the herbivores live longer which means they eat more food, food being producers causing producer numbers to fall drastically

Charles Darwin’s findings were pivotal to the formation of the theory of evolution. He noted that the Galapagos Islands, which are located about 1,000 kilometers away from South America, were made up of different types of finches. These species were all believed to have evolved from a species on the mainland, but they developed different adaptations to survive in their environment. Based on this information and the image, answer the following questions.
Answer:
What is the Galapagos Islands in Ecuador the site of Darwin's note on?
Darwin first came to the Galápagos in 1835, on a ship called the HMS Beagle. His observations of wildlife on the island inspired his theory of evolution by natural selection

match each hyposthesis for how the moon formed with the statement that best descibes it
Giant Impact Theory: The Moon was formed by a collision between Earth and a planet the size of Mars.
Colliding planetesimal Hypothesis: Planetesimals collided and merged to form the Moon.
Capture Hypothesis: As it passed past, Earth's gravity locked the Moon into orbit.
Accretion Hypothesis: The Moon was produced from the same material cloud that created the Earth.
According to scientists, the following are the recognized theories of lunar formation:
What is giant impact theory?According to this idea, a Mars-sized object named Theia collided with Earth, leaving a large portion of the planet to float in space, eventually forming the Moon. This is the most widely accepted idea of all since the Moon is moving away from Earth and its rocks are fairly similar to those of Earth.
1: According to this idea, the Moon was born somewhere else and was drawn into Earth's orbit by its gravity as it passed by.
2. Capture Hypothesis: According to this idea, the Moon and Earth arose from the same cloud of material at the same time.
3. Accretion Hypothesis: According to this idea, a vast number of small rocky objects known as planetesimals crashed and merged over a long period of time.
4. Colliding planetesimal Hypothesis: According to this idea, the Moon was formed by a huge number of small rocky objects known as planetesimals colliding and combining over a long period of time.
