What ended the last ice age?
That CO2 then warmed the globe, melting back the continental ice sheets and ushering in the current climate that enabled humanity to thrive. That, at least, is the story told by a new paper published in Nature on April 5 that reconstructs the end of the last ice age.

Answer:
The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:
1) root pressure (osmosis)
2) capillary action (adhesion)
3) evapotranspiration (cohesion)
Explanation:
The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.
Hope this helps.

A. Condensation
B. Infiltration
OUTPUT
C. Sublimation
STATION
D. Evaporation
3.
Answer:
1. D
2. B
3. A
Explanation:
The dashed circle indicates the process of infiltration because the water of precipitation goes inside the soil. Infiltration is the process in which water enters the soil through small opening present on the earth surface. When the clouds are formed, precipitation occurs in the form of rainfall and snowfall. Condensation is a process in which water vapors change into liquid when the environment has low temperature or cool so condensation occurs on the windows of Erica.

Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn't occur?
Hello. You have not shown the model of meiosis to which the question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
Crossing over is a genetic phenomenon that occurs when two sister chromatids are broken at some points and the pieces are exchanged between them. these exchanges cause the appearance of completely new gene sequences, which can completely affect the expression of stretches in the cells where the crossing over happened, since this cell will have a different gene sequence than the others.
As you may already know, chromosomes are formed by two filaments, called a chromatid. These filaments are united by the centromeros and the union of two filaments and a centromero is called sister chromatides.

Hawks
A minor decrease in rainfall
The field mice population slightly increasing
The introduction of a second predator that eats field mice
0 A parasitic infestation that reduces the cricket population
Answer:
I think it is A Parasitic one
Explanation:
A decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.
A food web is a diagram that represents the relationships between different groups of organisms in an ecosystem.Producers (e.g., plants) are organisms that maintain the entry of matter and energy to the food web.Rainfall is fundamental for maintaining the life of land producers (in this case, grasses) in the food web.In conclusion, a decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.

Although longitudinal waves can travel through all media types, what is the disadvantage of this type of wave transmission? Particles become too close together as they bump into each other making it more likely to hit other particles down the line. The waves travel in all directions which does not ensure that it will come into contact with particles down the line. The efficiency of the wave transmission is greatly diminished as the media becomes less dense. The oscillation of one set of particles has a huge impact on neighboring particles.
Answer:
The efficiency of the wave transmission is greatly diminished as the media becomes less dense.

11. If the decomposers were removed from an ecosystem, what would
most likely occur?
Energy from the sun would not be absorbed by plants
Carnivores would have no source of energy
Essential elements would not be available to plants
Herbivores would lose their source of energy and nutrients
Answer:
If decomposers are removed from ecosystem,there would be no organic nutrients and all the dead plants would destroy the animals habitat. The ecosystem will be fill by plants and animal wastes as there will be no decomposition of waste material.
If the decomposers were removed from an ecosystem then essential elements would not be available to plants. The correct option is C.
What are decomposers?Decomposers eat dead things like leaf litter and wood, as well as animal carcasses and feces.
As Earth's cleanup crew, they provide a valuable service. Dead leaves, insects, and animals would pile up everywhere if decomposers did not exist.
They play a critical role in decomposing complex compounds (dead organisms) into simple components.
Scavengers and decomposers break down dead plants and animals. They also decompose other waste of organism.
Decomposers are critical components of any ecosystem. Plants would not receive essential nutrients if they were not present in the ecosystem, and dead matter and waste would accumulate.
Thus, the correct option is C.

What is a food web?A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem. In a food chain, the various arrows symbolize the various species that are being consumed by one another and so represent the flow of energy. Additionally, it shows that an animal can eat a variety of foods.
Food chains that are linked together form food webs. In a food chain, arrows point from the organism being eaten to the organism eating it.
The energy flow in a food web is depicted by arrows. Food webs display every form of eating in an environment.
Thus, the correct option is B. eats more than just frogs.

how do the kidneys and the bladder work together??
Answer:
From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.

What part of Henry's cochlea may have functional hair cells?
The organ of Corti of Henry's cochlea may have functional hair cells, it is the structure that makes the hearing organs.
What is cochlea?Sound waves enter the ear from the outside environment and pass through the external auditory canal before they hit the eardrum and cause it to vibrate.
The incus collects sound vibrations from the malleus, also known as the "hammer," which connects to the eardrum, and sends them on to the stapes.
The stapes are a network that moves the oval window in and out. This motion is collected by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ, and small hair cells that make up the lining of the cochlea.
Therefore, the organ of the Corti part of Henry's cochlea may have functional hair cells.
