What did the Aztecs do to keep the universe in motion?

Answers

Answer:

Abstract

Two oppositional, yet complementary, sets of myths are presented here. These sets appear based on a concept of transformation which implies that the cosmos will collapse if a paradigm of human sacrifice is not followed-a paradigm for moral action utilized by Aztec kings in an amoral universe requiring constant nourishment. Models of this paradigm are seen to shape ethical decisions in two different examples: (a) crises of drought, and (b) problems of childraising. It is suggested that this moral and ethical information is presented to us, in varied sources, as an ontological reality which was gained by the direct experiencing of rituals participated in from infancy to death.

Journal Information

Founded in 1973 to "assist in shaping and locating the advanced edge of scholarly work in religious ethics." The Journal of Religious Ethics is committed to publishing the very best scholarship in religious ethics, to fostering new work in neglected areas, and to stimulating exchange on significant issues. Neither a tradition-specific journal of social ethics nor a tradition-neutral journal of philosophical ethics, the JRE offers serious ethical reflection set in the context of specific religious traditions and communities. The journal seeks to publish essays in three domains: studies in comparative religious ethics, considerations of foundational conceptual and methodological issues, and historical studies of influential figures and texts. An independent scholarly journal, the JRE is currently edited at Florida State University.

What are the roles of the DNA, RNA Polymerase, mRNA, tRNA and ribosome in protein synthesis

Answers

Answer:

mRNA molecules carry the coding sequences for protein synthesis and are called transcripts. rRNA molecules form the core of a cell's ribosomes, the structures in which protein synthesis takes place. tRNA molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

The sense organs of a cat work together to enable them to respond quickly and appropriately to stimuli in its environment.

What are the sense organs in a cat?

Cats have highly developed senses that enable them to respond quickly to stimuli in their environment.

The senses and sense organs in a cat are as follows:

Vision: Cats have excellent night vision and can see well in low light conditions. Their eyes have a tapetum lucidum, a reflective layer that enhances their vision in dim light. They have a large number of rods in their eyes which help them detect movement and light in low light conditions.Hearing: Cats have highly sensitive ears that can detect high-frequency sounds beyond the range of human hearing. They have 32 muscles in their ears which allow them to rotate their ears 180 degrees, helping them locate the source of the sound.Smell: A cat's sense of smell is highly developed, and they use it to identify prey, locate food, and recognize other cats. They have an olfactory epithelium in their noses which helps them detect scents that are not detectable by humans.Taste: Cats have fewer taste buds than humans, and their sense of taste is not as highly developed. However, they can distinguish between sweet, sour, salty, and bitter tastes.Touch: Cats have sensitive whiskers and highly sensitive paws that allow them to feel vibrations and textures. Their whiskers help them navigate in the dark and sense changes in their environment.

In response to stimuli, cats will use their senses to assess the situation and determine their response. For example, if they detect a high-frequency sound, they may rotate their ears to locate the source of the sound and then determine whether it is a potential threat or not. If they smell a strange scent, they may become cautious or alert and investigate the source of the smell. If they see a moving object, they may use their highly developed sense of vision to assess whether it is prey or a potential threat.

D.

Answers

Answer:

The Answer is A. the chemical inhibits the carrier potein for pyruvate in the mitochondrial inner membrane.

Explanation:

I just took the test so I know this is right

The statement regarding the effect of the chemical that is reasonable is that the chemical inhibits the carrier protein for pyruvate in the mitochondrial inner membrane. The correct option is A.

What is carrier protein?

Carrier proteins bind the specific solute to be transported and then go through a series of conformational changes to move the bound solute across the membrane.

Carrier proteins bind specific solutes and transport them across the lipid bilayer by going through conformational changes that expose the solute-binding site on one side of the membrane and then the other.

Carrier proteins, like other membrane transport proteins, are found in lipid bilayer cell structures such as cell membranes, mitochondria, and chloroplasts.

A reasonable statement about the chemical's effect is that it inhibits the pyruvate carrier protein in the mitochondrial inner membrane.

Thus, the correct option is A.

Describe the major differences between the ecological niches of humans and cockroaches. Are these two species in competition? If so, how do they manage to
coexist?

Answers

(Essay) Describe the major differences between the ecological niches of humans and cockroaches. Are these two species competition?
Humans: large omnivorous animals, apex predator in many ecosystems
Cockroaches: small detrivores.

Humans: Sleep at night.
Cockroaches: Spend daytime hidden away, preferably in dark crevices.

Humans: Extensively modify the environment.
Cockroaches: Some species can burrow.

Are these two species in competition?
No. Our diets overlap a bit (e.g. stored grains), but we exploit food sources that cockroaches can't, and vice versa. We do not compete for homesites or mates at all.

The major differences between the ecological niches of humans and cockroaches depend on the functional role they play, the space they live, and the group (trophic level) they belong.

What is an Ecological niche?

An ecological niche can be regarded as an area or set of environmental factors or the surroundings of an individual where they perform their functional role.

Humans being omnivores have a generalized niche where they particularly have many options to play a functional role (feeding habit).

Cockroaches play the role of decomposers which is also an important part of any ecosystem. Living organisms are interdependent, so they need each other in order to survive. Therefore, it is wrong to say that humans and cockroaches are in competition. Cockroaches unlike humans live in really dirty and dark places because in such conditions they easily find food. While humans take a rest in dark (night) and search for their food in the daytime.

Humans take fresh and cooked food, while cockroaches shred dead and decaying organic matter into smaller pieces so that it would be eaten by recycling bacteria.

Therefore, these two different species are not in direct competition and survive without affecting each other's ecological niche.
