What are the taxonomic classes?If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.
Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.
The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.
The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.
Therefore, option D is correct.

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
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.

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.

How does the experiment contribute to our understanding of altruism in different creatures?
Answer:
TWO YEARS AGO, a group of Ugandan chimps provided a blow to the idea that humans are the only animals that truly behave selflessly to one another. These chimps showed clear signs of true selflessness, helping both human handlers and other unrelated chimps with no desire for reward.
The question of why we help each other, instead of looking out for ourselves, is one of the most compelling in modern biology. Evolutionary and game theory alike predict that selfish behaviour should be the rule with altruism the exception, and animal experiments have largely supported this idea. Nature, ‘red in tooth and claw’, is painted as a fierce competition between selfish individuals and their even more selfish genes. In this stark landscape, true altruism is apparently a rare quality and some scientists believe that it’s one

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.

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

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.

6. What did Watson, Crick, and Franklin discover about the structure of DNA?
7. How did Watson, Crick, and Franklin's work reiterate Chargaff's findings?
1. adenine
2. phosphates
3. antiparallel
4. X-ray crystallography is a technique used to learn more about the three-dimensional structure of biological molecules. In x-ray crystallography, a molecule (for example, DNA) is crystallized. Then, x-ray beams are directed onto the molecular crystal. The pattern of diffraction, or bending, of the x-rays provides information about the physical properties of the molecule. Rosalind Franklin used x-ray crystallography to investigate the three-dimensional structure of DNA.
5. Watson and Crick were interested in learning more about the physical structure of DNA. They had come up with several hypotheses about how DNA could be structured, but they needed more concrete evidence of the molecule's structure. Rosalind Franklin's Photo 51 provided important information to Watson and Crick as they worked on a model of the three-dimensional structure of DNA.
6. Photo 51 confirmed that DNA is a double helix. Watson and Crick's model of DNA included that it is antiparallel, and that each base pair is held together by hydrogen bonds. The DNA chain is comprised of an outer backbone alternating between the sugar deoxyribose and phosphate groups. The base pairs, which are held together by hydrogen bonds, are located on the inner portion of the double helix.
7. Chargaff found that the number of adenine nucleotides was always roughly the same as the number of thymines, and the number of cytosines was about the same as the number of guanines. This provided the insight that in the DNA double helix, A selectively bonds with T, while G bonds with C. This explains why Chargaff consistently found that the number of As and Ts, and the number of Cs and Gs, were the same in his studies.

Which of the following occur in a maple tree growing in a temperate climate in response to increasing cold weather? Choose three correct
answers.
A. Auxin production stimulate one final growth spurt before winter arrives,
B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments.
C. Xylem and phloem fill with ions and organic substances that prevent freezing.
D. Meristems form thick scales to protect next year's buds from cold winter temperatures,
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,
