Answer: Option A, C and D.
Explanation:
Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.
If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures
But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.
Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.
They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,

Fill in the blank. Giraffe necks and mice necks have the same number of vertebrae, despite their different sizes and functions. This is an example of a(n) _______. The wings of insects, bats, and birds are structurally different but achieve similar functions. This is an example of a/an _______. The peppered moth provides an example of _______, as the predominant color of moths changed over time as pollution dictated which color was best camouflaged for protection from predators. Respond to the following based on your reading. Two species, a cactus and a Venus fly-trap, have a water intake system that's similar in function but not in structure. What type of structure is this? A scientist is trying to determine if two species are closely related or if they just have the same external features. What would you look for to make this determination? You go to school and discover that your friend got admitted to the hospital for a burst appendix. You want to learn if the appendix serves a function in our bodies. What would you need to research? A species of beetle in Africa looks really similar to a different species in South America. How would the environment influence species development? Why does Australia have so many genetically distinct organisms?
Answer:
homologous structure
analogous structure
natural selection
This is known as an analogous structure.
To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.
To learn more about why your friend is in the hospital, you should research vestigial structures.
These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).
Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

Sleet is precipitation made of small particles of ice. How does sleet form?
Answer:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
hope this helps!
Answer:
There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.

Would all of the reptiles in an area be considered a population? Explain.
All the reptiles which are living in an area can be considered as a population technically. Thus, the reptiles can be a population.
What is a Population?A population is any kind of complete group with at least one characteristic in common between different species. Populations are not just people or organisms. But, the populations may consist of, however are not limited to, people, animals, businesses, buildings, motor vehicles, farms, objects, or events.
Population data contains various types of influential details such as birth, death, demographic information such as the age, sex, annual income, occupation, language of the species in an ecosystem. The overall socio-economic, economic, political, cultural progress of a country is dependent upon the population data to a large extent.

Why is water so effective at hydrogen bonding?
Choose 1 answer:
(Choice A)
The hydrogens in water are ionically bonded to the oxygen.
(Choice B)
Hydrogen is more electronegative than oxygen, so it is more likely to donate its electrons to oxygen.
(Choice C)
Oxygen is very electronegative and strongly attracts hydrogen's electron.
(Choice D)
There are two hydrogens, doubling the positive charge on the water molecule.
Answer:
Choice A
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

What term describes a species whose removal would affect many other species, both directly and indirectly
A. predator species
B. Keystone species
OC. cascading species
OD. phoresy species
Next
Answer:
Keystone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

Example of how organisms that were previously thought of as related are actually more genetically related to organisms outside their species?
Answer:
Explanation:
Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.
But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.

What is living organism ?The environment consist of both living and nonliving organisms with two interacting components such as Physical or abiotic and biological or biotic components.
The physical component are temperature, light, soil, air, and water where as the biological component are animals, plants, and microorganisms.
The biotic components are plants, animals, and micro-organisms while green leaves of the autotrophic plant have chlorophyll and this pigment help in making food using light, water, and carbon dioxide by the process of photosynthesis.
Animals on the other hand are heterotrophs need nutrients and absorb nutrients such as nitrogen, phosphorus, and calcium from the soil.

Joey eats strawberries for lunch. Explain how homeostasis is maintained in the endocrine systems once the fruit has entered Joey’s body.
Answer:
Explanations:
Homeostasis can be defined as the phenomenon whereby there is balance or stability within the internal and external environment of a cell or the body. The internal environment of the organism is kept constant during homeostasis. During this process there is adjustments in the
internal environment Because there is always change in the conditions inside and outside the cell. When the system of the body is able to adjust itself it's reffered to as homeostatic regulation.
The endocrine system which contains glands that is responsible for the secretion of hormones into the bloodstream play also vital part during Homeostasis, This is because hormones which are the chemical messaged effect some change cells in another part of the body. The endocrine system is responsible for the regulations of
metabolism as well as the development of some body cells and systems via feedback mechanisms, hormones such as
Thyrotropin-Releasing Hormone during Homeostasis. Therefore as Joey eats strawberries for lunch the hormones makes adjustment of muscle metabolism and also regulate fluid and ion concentration in the system or body

Faults form because crust gets cracked when plates move apart along divergent plate boundaries.
sy
Answer:
The correct option is D: Faults form because crust gets cracked when plates move apart along divergent plate boundaries.
Explanation:
Options A and B are incorrect because even though tectonic plates are constantly moving and crashing against each other at convergent plate boundaries, it is not responsible for causing an earthquake. Option C is also incorrect in the context of the question statement merely colliding does not result in an earthquake.
Hope that answers the question, have a great day!
(also, please remember to give 'brainliest' if you found this answer helpful :)
Answer:
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.
Explanation:
Due to the movement of the plates in two different directions, the crust gets cracked and this leads to the formation of divergent boundaries that pulls the two sides apart, and as a result, the earthquakes are created and some of them may occur in the same location. Rift valleys are also formed by this process.
During mitosis, the original cell produces two daughter cells. How many daughter cells will be produced if 250 mouse cells undergo mitosis?
Answer:
There would be 500 daughter cells if 200 mouse cells went through the process of mitosis. (If that's what your asking)
Explanation:
During mitosis, the organism (which would be an asexual producer) doubles the amount of chromosomes and they divides the doubled number by two. So the organism will always end up with two daughter cells with the same number of chromosomes as itself. (That is the way with asexual producer's-their offspring is always an exact replica of the first). Now, if you take one mouse, it would end up with 2 daughter cells. If 250 mice reproduce, each with two daughter cells, then there would be 500 daughter cells in total, because you would multiply 2 by 250.
The number of daughter cells that will be produced is; 500 daughter cells
Mitosis is a process of cell replacement or cell growth whereby a cell divides into two exact daughter cells containing the same number of chromosomes each as the number of chromosomes contained in the parent cell.
Given that the original cell produces two daughter cells, when 250 mouse cell undergoes this process we will have
250 * 2 = 500 daughter cells.
Hence we can conclude that the number of daughter cells that will be produced is 500 daughter cells
