Question 2 please help choices are prokaryote or eukaryote
Answer:
1. Circular chromosome, no mitosis = PROKARYOTES
2. Sterols in membrane, performs exocytosis = EUKARYOTES
3. Cell wall and mitochondria present = EUKARYOTES
4. Spirillum shape present = PROKARYOTES
Explanation:
Prokaryotes are organisms that notably lack a membrane bound nucleus while eukaryotes possess a membrane bound nucleus. Although, there exists other characteristics and features that distinguishes these two domains of organisms.
- Circular chromosome is a feature possessed by prokaryotic organisms e.g. bacteria. Also they do not undergo mitosis, instead they perform binary fission.
- Sterols are a class of lipids present in the membranes of all eukaryotes. Prokaryotes lack this feature. Also, eukaryotes perform the process of exocytosis, which is how eukaryotic cells release waste particles outside the cell.
- Mitochondria is a structure present only in eukaryotic organisms. Hence, an organism that possesses both cell wall and mitochondria is an EUKARYOTE.
- Spirillum is a characteristics of spiral shaped bacteria called spirochetes. Since bacteria are prokaryotic, hence, the spirillum shape is a prokaryote.
A scientist studies how the number of coyotes in San Diego County has changed over the last decade. Is this a population-level study, a community-level study, or an ecosystem-level study?
Answer:
Population level
Explanation:
Ecological studies can be performed at different hierarchy levels:
Organism Population CommunityEcosystemPopulations are groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring, and living in the same habitat at the same time. These groups are reproductively isolated from other species groups. Individuals belonging to a species cannot reproduce with members of other species.What results of interest about this organization level is knowing the minimum size of the population needed to leave fertile offspring that ensure the population will survive over time. Genetic variability is also a significant factor because it allows evolutive adaptation to environmental changes. A population might be severely affected by evolutive forces such as genetic flow, genetic drift, and natural selection.
When analyzing the evolution of a population in time, there are parameters to consider regarding its size, such as the generational time, growth rate per capita, the net reproductive rate, the reproductive value, among others.
A community might be defined as a group of organisms of different species that coexist in a specific time and space.When ecologists talk about a Community, they refer to the existing interaction between different species that share the same habitat and at the same time. What results of interest about the study of this organization level are the inter-specific interactions. These interactions involve competition, predation, parasitism, mutualism, etcetera, and each species carries out a different role in these interactions. These relationships and the results are what determine the destiny of the populations and their size.
The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings. These are constantly interacting. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.
Every abiotic component influence organisms and their survival and reproductive rates.
When analyzing how the number of coyotes in San Diego County has changed over the last decade, we are performing a population-level study. We need to know how the population changed its size through the years, but not the interactions with other species or abiotic factors. Interactions are not of interest in this study.
How does the chain of amino acids determine the shape of a protein?
Answer:
ok mark me brainliest also have a good day
Explanation:
A protein's shape is determined by the sequence of amino acids that make up the protein. The order of the amino acids, or the primary structure, determines the folding of the amino acid chains or tertiary structure. The interactions between the side chains and the amino acids determine the folds of the protein. and The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. ... The final shape adopted by a newly synthesized protein is typically the most energetically favorable one.

5. In a food web, what is the role of detritivores and decomposers and at what level do
they work?
Answer:
Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as faeces). There are many kinds of invertebrates, vertebrates and plants that carry out coprophagy. By doing so, all these detritivores contribute to decomposition and the nutrient cycles. They should be distinguished from other decomposers, such as many species of bacteria, fungi and protists, which are unable to ingest discrete lumps of matter, but instead live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). However, the terms detritivore and decomposer are often used interchangeably but they are different organisms. Detritivore are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter. Allowing for decomposers to perform the second stage of remineralization.
Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.
