Take three test-tubes. Fill each other with water. Label them A, B and C. Keep a snail in test-tube A, a water plant in test-tube B and in C, keep snail and plant both.
Which test-tube would have the highest concentration of Carbon dioxide.
Answer:
Living organisms use oxygen and release CO2 during respiration.
Test tube A consists of snail which continuously uses the oxygen produced and releases carbon dioxide.
Hence, test tube A will have the highest concentration of carbon dioxide.

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 difference between a Class I and a Class II tRNA synthetase is (select all that apply):
a. the Class I synthetase reaction requires a transesterification reaction not necessary in the Class II reaction.
b. the Class I synthetase uses the 2' OH of the 3' end of the tRNA as a nucleophile and the Class II uses the 3' OH.
c. the Class I synthetase requires ATP as a cofactor and the Class II does not.
d. the Class II synthetases are typically monomeric, whereas the Class I enzymes frequently function as multimeric protein complexes.
Answer:
Option b is the correct answer.
Explanation:
The 2' OH of each 3' end of the tRNA is used as a nucleophile by Class I synthetase, whereas the 3' OH is used by Class II.
The Class I aminoacyl-tRNA synthetase attaches amino acids to the 2'-OH group of the tRNA's 3'-end ribose residue, whilst the Class II synthetase attaches amino acids only to the 3'-OH group of the tRNA's 3'-end ribose residue. Both Class I and Class II enzymes conduct the transesterification process and the need of ATP.
What we have is option d is incorrect because, Class I enzyme is typically monomeric, while the Class II enzyme is dimeric or multimeric in nature.

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.

How do heart rate and cellular respiration relate to each other?
Answer:
Several changes take place in the body to enable this: the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

How are taste and smell related? (if you put a link or the wrong answer you will be reported)
Answer:
Smell and taste are closely linked. The taste buds of the tongue identify taste, and the nerves in the nose identify smell. Both sensations are communicated to the brain, which integrates the information so that flavors can be recognized and appreciated.
hope this helps
have a good day :)
Explanation:
Answer:
Your mouth and nose is basically connected, and example you smell something and its spicy, right? So when you taste it, it's just as spicy as it smelt. I hope that answered your question :/

Describe how the Hawaiian islands have formed.
Answer:
Explanation:
The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism. ... The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate.
The Hawaiian Islands were formed by a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.
What is hotspot?
"In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle".
What is Pacific plate ?
"The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate".
