What will be the advantages and disadvantages if the world was covered in water?
Answer:
1) no water loss from evaporation
2)less temperature fluctuation
3)less light, so predators can't see them
4)avoid competition w/ terrestrial species
Which of the following statements accurately explains the relationship between time of day and water transport through the plants? (Answer choices in the photo, and a graph.)
The best option would be the letter B. At night, the stomata are closed so water in the leaves cannot evaporate, which reduces the need fro absorption of water at the root.
In eukaryotes, the components of citric acid cycling and the electron transport chain are located in the ____.
In eukaryotes, the citric acid cycle takes place in the mitochondrial matrix. Glycolysis occurs in the cytosol. Electron transport chain includes both the intermembrane space and the inner mitochondrial membrane.
Pyruvate from glycolysis is transported to mitochondrial matrix for the citric acid cycle to take place. The citric acid cycle is where acetyl CoA is modified in the mitochondria to produce energy precursors required for the next step.
The process where electron transport from the energy precursors from the citric acid cycle leads to the phosphorylation of ADP, producing ATP is Oxidative phosphorylation. The Electron transport chain is embedded within the extensive inner membrane of the mitochondrion close to the mitochondrial matrix in which the TCA cycle is localized .

Eukaryotic genomes comprise mostly noncoding DNA, whereas prokaryotes have mostly coding DNA. So the correct option is (b).
Prokaryotic chromosomes are found in the nucleoid, while those of eukaryotes are found inside the nucleus. Eukaryotic cells contain a membrane-bound nucleus (as well as membrane-bound organelles), whereas prokaryotic cells have not. This is the primary distinction between the two types of cells.
Prokaryotic genomes have less noncoding DNA compared to eukaryotic genomes, which have a lot of it. Bacteria typically have circular chromosomes, whereas eukaryotes typically have linear chromosomes. Eukaryotes and prokaryotes both have negatively supercoiled double-stranded DNA.
Therefore, eukaryotic genomes comprise mostly noncoding DNA, whereas prokaryotes have mostly coding DNA. So the correct option is (b).

Remembering that proteins are made in cells that are 70% water- and water is polar-
describe how you might imagine that a protein spontaneously folds up into a complex 3D
shape.
The protein structure is divided into 4 levels. The primary structure is made up of peptide bonds connecting the amino acid chains. One's N terminus forms a relationship with another's C terminus.
The initial step of folding is secondary structure. The amino acid chain may create structures like the Alpha helix and Beta sheet by hydrogen bonding with itself.
How is protein structure impacted by polar?A protein's overall structure is impacted by the polarity of its amino acids. Due to the hydrophilic characteristics of the side chain, polar amino acid residues frequently occur outside of proteins.
The folding and intramolecular bonding of a protein's linear amino acid chain are driven by the protein's fundamental structure, or its amino acid sequence, which ultimately defines the protein's distinctive three-dimensional form.
When multiple amino acids combine to form a protein, each amino acid's special characteristics dictate how the protein folds into its ultimate 3D structure. The protein may carry out a particular job in our cells because of its structure.

Type of inheritance pattern that is best described below is Multiple Alleles.
Multiple alleles are the alternative forms of the same gene so they influence the same trait. The wild-type allele is mostly dominant over the mutant alleles.
Multiple alleles exist in a population when there are many variations of a gene present. In organisms with two copies of every gene, also known as diploid organisms, each organism has the ability to express two alleles at the same time. They can be the same allele, which is called a homozygous genotype. Multiple allelism, occurs when more than two gene forms exist for the same locus.

What are the X and Y chromosomes
geneticists often assume that map distances less than 7 to 8 map units (m.u.) are accurate. map distances that exceed this threshold significantly are assumed to be less accurate and the level of accuracy declines as map distances increase. briefly explain this observation.
The further apart two genes are the more likely it is that multiple crossovers will occur.
Even if there has been crossing over, the offspring may still have parental genotypes that are not considered recombinants if there is a double crossover (or an even number of crossovers) between two genes. Double crossings will cause the real map distance to be underestimated since genetic maps are constructed by counting visible recombinants in the progeny.
The middle allele is transferred from one sister chromatid to the other during a double-crossover event, which is the following crucial step. As a result, the surrounding genes' parental alleles and the non-parental allele of the middle gene are positioned on the same chromosome.

We know that frequency of recessive individual in the total population is equal to the proportion of the population is most likely heterozygous (a1a2) for this trait is 0.50. correct option is (C).
Heterozygotes are indistinguishable from the homozygous dominants
This means that the phenotype of offspring with genotype Aa and AA would be the same. One who possesses distinct or non-identical alleles for a specific trait at the same locus on homologous chromosomes is said to be heterozygous. This definition applies to cells, nuclei, and entire organisms. In contrast to homozygosity, in which the alleles are identical, it signifies that the alleles that code for the same gene or trait are different.

If a person is at least 18 years old and has a legal right to possess a handgun under state and federal law, they are permitted to carry a firearm openly without a license. There are some places that are off-limits, such courts and schools.
It is a society that recognizes the right to carry a concealed weapon within the state without first acquiring a concealed handgun license. This law may seems okay for some people, but its negative implications outweigh its advantages.
With the high rise in gun violence, there is therefore the need to amend this law. The Second Amendment does not protect concealed carry of arms, according to opponents of the practice, who also contend that police personnel with the appropriate training should be in charge of ensuring the protection of the public.

They can also be created in various ways, although typically they are created during the alpha decay process.
