During childbirth, a hormone produced by the pituitary gland causes muscles of the mother's uterus (or womb) to contract. The more contractions there are, the more hormone is produced.

Which best explains why this occurs?

A. Positive feedback is used to build more contractions.

B. Positive feedback is used to lessen the effects of the contractions.

C. Negative feedback is used to build more contractions.

D. Negative feedback is used to lessen the effects of the contractions.

Answers

Answer 1

Answer:

Positive feedback is used to build more contractions.

Explanation:

Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.

The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.

Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.  

The positive feedback loop continues until the baby is born.

Answer 2
Positive feedback is used to build more contractions

Life as an Aquatic Larva

Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. After the egg hatches, the free-crawling aquatic larva molts once and then starts hunting voraciously. As the larva grows, it will molt numerous times. Most dragonfly larvae mature to adulthood in one to three years. so maybe *(c.)

People claim these rock formations in the Sahara Desert look like a mushroom and a chicken. They were not sculpted by humans. What do you think caused them to be shaped this way?

Answers

mainly because of erosion by the wind, which geographers call abrasion. When the wind blows in some hot deserts it will pick up millions of grains of sand. When the wind hits an outcrop of rock the sand it is carrying is blasted against it. Over time it would form to become that funky mushroom shape.
hope this helped! :))

The process is known as erosion and it leads to the creation of a large number of shales and sizes of structures such as a pedestrian or mushroom-shaped rocks that have a wide top and a narrow base.

The rocks were re-sculpted as per the wind direction and intensity. Due to the action of wind the and is carried and is known as the abrasion process. The grains of sand are used as tools to polish the surface of the rocks.

why is it important to understand the relationship amoung organisms in an ecosystem

Answers

Relationships Between Organisms:


Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings.
All organisms in an ecosystem are connected in one way or another. In fact, populations of different species generally interact in a complex web of relationships. Relationships between species in communities are important factors in natural selection and help shape the evolution of the interacting species.

In January, the temperature in the southern part of Florida dropped below freezing several nights in a row. One fruit grower commented that climate was really bad for the orange crop this year. Why was his comment incorrect?


Climate refers to precipitation instead of temperature so the climate did not change.

Cold weather can sometimes occur even in a warm climate such as southern Florida.

It would have to be cold for many nights in a row to indicate that the climate had changed.

The climate in Florida does not ever change so it is only the weather that can be bad for the crop.

Answers

He was talking about weather, not climate. The climate is still fine, but for a short time, that weather was not good for the oranges. I believe the answer is the last one

B) when each process happens
C) why each process happens when it does

Answers

Answer:

It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out

Explanation:

process: respiration, and photosynthesis

when: as soon as sun rises

why: Plants and animals, in turn, convert the food compounds by combining it with oxygen to release energy for growth and other life activities

divergent plate boundaries can form chains of underwater mountains, called mid-ocean ridges. Explain how the formation of these ridges occurs.
Your answer should include at least two complete sentences.
Be sure to check your grammar and spelling.

Answers

!

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.


ℎ ℎ ❣︎
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
