What 2 body systems Uterus contracts to give birth

The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? (2 points) Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.

Many plants have the ability to respond to herbivores. Some plants produce substances
which are distasteful or toxic in response to an herbivore attack. Which of these is the LEAST correction description of the plant system interactions involved?

A. Carbon dioxide diffuses through stoma into leaf tissues, where it is fixed into organic compounds
which may serve as building blocks for chemical defenses.

B. Root systems obtain water and key minerals from the soil where they are transported to the affected site.

C. Shoot systems carry carbon dioxide, water and nutrients from leaves directly to the affected
plant part, where chemical defense molecules are produced.

D. Chemicals found in a herbivore's saliva trigger chemical messengers which trigger production of
defense molecules

The inflammatory response is an innate reaction to invasion by a pathogen regardless of whether that pathogen had been previously encountered. Which statement best describes the symptoms of redness and swelling at the site of a splinter after its removal? A) Interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling. B) Interactions of the respiratory and immune systems create an increased breathing rate and immune cell metabolism, which can lead to redness and swelling. C) Interactions between the immune system and digestive system increase the digestive enzyme activity at the site of the infection, which leads to redness and swelling. D) Interactions of the immune system and nervous system lead to increased cellular communication and hormonal activity at the site of the infection, which causes redness and swelling.

All of the following are true of photosynthesis except

Hummingbirds need large amounts of energy to flap their wings between 60 and 200 times per second. Their wings beat so rapidly that it is difficult to see them move. They often appear suspended in air for extended periods of time without changing their location. Hummingbirds have long bills and grooved tongues to reach into flowers to feed on flower nectar. They also feed on insects.

The body system most directly interacting with the skeletal system to enable hummingbirds to beat their wings between 60 and 200 times per second is the-

F.
muscular system.

G.
integumentary system.

H.
endocrine system.

J.
circulatory system.

C. a traffic signal
D. a street sweeper

The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time?
Choose the correct answer.


Foxes were bred to meet human needs for white fur.

Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring.

Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring.

Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

The bacterial DNA can be found in the

A student was injured in an accident which caused the Renal Artery to fail. A matching organ donor was unavailable, and as their doctor, you must repair the damage. You have two options: Harvest body(somatic) cells from his other kidney and transplant them into the damaged kidney. Harvest stem cells from his bone marrow (as shown above) and transplant them into the damaged kidney.
