Rainbow trout live in the rivers and streams of upstate New York. Rivers in this area are cold and have strong currents. If temperatures fall over time because of climate change, what is one variation that would likely help the trout to survive? Why? Write 1-2 sentences.(2 points)
Tolerance towards cold temperature and adaptabilities are the variation that help the trout fish to survive.
Which factor help the trout to survive?If temperatures fall over time because of climate change, the tolerance towards cold temperature is the one variation that would likely help the trout to survive because only those organisms survive in cold temperature that have good tolerance and various adaptation towards cold temperature.
So we can conclude that tolerance towards cold temperature and adaptabilities are the variation that help the trout fish to survive.

Describe the structure of the digestive system.
Answer:
[tex]\bold{Structure \: of \: digestive \: system}[/tex]
The digestive system is made up the GI tract or digestive tract and the liver, pancreas, and gallbladder.The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.The small intestine has three parts :The first part is called the duodenum. The jejunum is in the middle the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.
It is necessary to have limitations in an environment because if not:
Traits from species would get crossed.
Water and shelter would be automatically created by extra species that are new.
The populations of the world would soon crowd one another out and make conditions unlivable.
The world would balance itself out without problems.
animals.
Plants would take over the space of animals
Best guess is "The populations of the world would soon crowd one another out and make conditions unlivable."
How does natural selection contribute to the theory of evolution?
Answer: Natural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve.

Which statements describe situations where organisms interact and depend on each other for survival?
Choose all correct answers.
1. Tree frogs use plants as protection from predators. The plants receive nothing from the tree frogs.
2. Zebras eat grass, Zebras spread the grass seeds to new locations in their droppings as they move with their herd.
3. Birds find shelter in trees as they build their nests and raise their young. Birds also eat the fruit on trees and then spread the seeds to new places in their droppings.
4. The oxpecker feeds on the insects that surround the rhinoceros, The rhinoceros has fewer bugs surrounding it.
Answer:
Predation is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey.
Herbivory is a form of predation in which the prey organism is a plant.
Predator and prey populations affect each other's dynamics. The sizes of predator and prey populations often go up and down in linked cycles.
Predators and prey often have adaptations—beneficial features arising by natural selection—that are related to their interaction. For prey, these include various defenses and warning signals, such as bright coloration.

(b) (a) The size of the soccer field you can have to yourself if you leave in a region containing 100 people per square mile is 2.25 fields.
Size of soccer field to yourself
The size of the soccer field you can have to yourself if you leave in the given regions is calculated as follows;
For 25 people per square mileSize per person = (225 field/mi²) / (25 persons/mi²)
Size per person = 9 field per person
For 100 people per square mileSize per person = (225)/100
Size per person = 2.25 field per person

The plants in this ecosystem are dark in color to absorb sunlight, covered in hair and grow in clumps. What type of ecosystem could a plant with these
adaptations be best fit for?
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.
What is tundra ecosystem?Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.
Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.
