During meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A as the daughter cells are called as gametes here.
What is meiosis?Meiosis is a type of cell division that results in the production of haploid cells from a diploid cell, and during meiosis, two rounds of cell division occur, referred to as meiosis I and meiosis II, and in meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over. In meiosis II, each haploid daughter cell produced in meiosis I divides again, and the sister chromatids, which are identical copies of the same chromosome, separate from each other.
Hence, during meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A.

The chemical reaction equation of photosynthesis is shown here:
6CO2 + 6H2O C6H1206
What information is not given in this equation,
It does not show if the reaction is reversible
It does not show the reactants needed for the reaction
It does not show that photosynthesis consists of many separate steps.
It does not show the number of molecules required to produce glucose.
Answer:
It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is the metabolic process whereby green plants manufacture their food from inorganic sources in the presence of sunlight as energy source. The chemical equation of the photosynthetic process is given as follows:
6CO2 + 6H2O → C6H1206 + 6O2
The above equation only shows a summary of the photosynthetic process, however, it fails to show that photosynthesis still requires a lot of separate steps to occur. For example, the water molecule undergoes photolysis while the CO2 molecule enters the Calvin cycle. Hence, this equation does not show that photosynthesis consists of many separate steps.

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its comp
Answer: The sequence will be 5' ATGAAC 3' and 3' TACTTG 5'.
Explanation:
DNA is a molecule that contains genetic information that codes for protein synthesis in all organisms. This molecule consists of two strands that coil together to form a double helix structure. Each of these chains is formed by nucleotides, which are the monomers of nucleic acids and are formed by the union of a five-carbon sugar (pentose) called deoxyribose, phosphate groups and a nitrogenous base. The nitrogenous bases can be:
Adenine (A) Cytosine (C) Guanine (G) Thymine (T)The two chains are held together by bonds called hydrogen bonds between the bases. Consider that A is only linked to T by two hydrogen bridges, and that C is only linked to G by three hydrogen bridges. This means, both chains are complementary to each other.
The 5' and 3' stand for "five prime" and "three prime", which indicate the carbon numbers on the sugar of DNA. For the classification of the pentoses (which are made of 5 carbones attached to each other), we consider that carbon with the phosphate group is the 5' carbon; and the carbon of with the hydroxyl group, is the 3' carbon. This asymmetry gives a DNA strand a "direction" and causes it to be considered antiparallel, meaning that the nucleotide at the 5' end is first and the nucleotide at the 3' end is last.
Then in this example, the sequence will be 5' ATGAAC 3' and 3' TACTTG 5'.

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.
