A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of: Sympatric speciation. Iterative evolution Evolutionary drift Genetic drift Lamarckian evolution
Answers
The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.
Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

percentage of thymine will each new strand have after replication?
A. 20%
B. 60%
C. 40%
D. 30%
Answers
Answer:
According to Chargaff's rule, if a DNA strand has 30% guanine before to semi-conservative replication, the percentage of thymine that will have each new strand after replication will be 20% (option A).
Explanation:
A DNA molecule stores the genome of a living organism in a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine. By knowing the percentage of a nitrogenous base in the DNA, the percentage of the other bases can be established using Chargaff's base pair rule.
Chargaff was able to establish that in a DNA molecule the ratio purine:pyrimidine is 1:1, so there must be the same amount of guanine as cytosine and a similar amount of adenine for thymine, taking into account the complementarity of the bases.
According to the base pair rule, if in a DNA strand there is 30% guanine, in the molecule there is:
Guanine 30%. Cytosine 30%. Thymine 20%. Adenine 20%. Total ..... 100%In this case, Chargaff's rule is useful to determine the percentage of thymine that each new strand will have after replication, corresponding to 20%.

Answers
Yes, green algae are more closely related to plants than they are to kelp. Green algae and plants belong to the same kingdom, Plantae, while kelp belongs to a different kingdom, Chromista.
Green algae and plants share several fundamental characteristics, such as photosynthesis, chlorophyll pigments, cell walls containing cellulose, and similar reproductive structures. These similarities suggest a close evolutionary relationship between green algae and plants.
Kelp, on the other hand, is a type of large brown algae that belongs to the kingdom Chromista. Brown algae are not classified within the plant kingdom but are part of a separate lineage. They differ from green algae and plants in various aspects, including pigments, cell wall composition, and reproductive structures.
Therefore, based on evolutionary relationships and shared characteristics, green algae and plants are more closely related to each other than they are to kelp.

Genetic sequencing technologies are evolving at a rapid pace with major implications for research and clinical practice. In this review, the authors provide an updated overview of next-generation sequencing (NGS) and emerging methodologies. NGS has tremendously improved sequencing output while being more time and cost-efficient in comparison to Sanger sequencing. The authors describe short-read sequencing approaches, such as sequencing by synthesis, ion semiconductor sequencing, and nanoball sequencing. Third-generation long-read sequencing now promises to overcome many of the limitations of short-read sequencing, such as the ability to reliably resolve repeat sequences and large genomic rearrangements. By combining complementary methods with massively parallel DNA sequencing, a greater insight into the biological context of disease mechanisms is now possible. Emerging methodologies, such as advances in nanopore technology, in situ nucleic acid sequencing, and microscopy-based sequencing, will continue the rapid evolution of this area. These new technologies hold many potential applications for hematological disorders, with the promise of precision and personalized medical care in the future.

which two forms of transport require proteins found in the cell membrane to move material in and out of a cell?
Answers
The two main kinds of membrane transport proteins are carrier proteins and channel proteins.
There are typically two types of transport carried out by transport proteins: "facilitated diffusion," in which a substance is simply allowed to diffuse down its concentration gradient, and "active transport," in which a cell uses energy to move a substance in the opposite direction of its concentration gradient.
The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane. Facilitated diffusion is the method by which these molecules travel across the membrane with the aid of specific transport proteins. These distinct proteins are connected to what are known as channel proteins or carrier proteins (Figure below).

The possible blood type if mom has heterozygous A and Dad has heterozygous B is AB or A or B or O.
Blood typeIn terms of the presence or absence of certain antigens, there are four types of blood types. Blood types A, B, AB, and O.
Heterozygous, as related to genetics, refers to having inherited different versions (alleles).
The heterozygous A means the genotype is \(I^{a} I^{o}\) and the heterozygous B means has the genotype \(I^{b} I^{o}\)
If both genotypes are crossed, the possible genotype that would be inherited to the offspring is as follow :
\(I^{a}\), \(I^{o}\) x \(I^{b}\), \(I^{o}\)
\(I^{a} I^{b}\), \(I^{a} I^{o}\), \(I^{b} I^{o}\), \(I^{o} I^{o}\)
Here is the expression (phenotype) of each genotype would be :
\(I^{a} I^{b}\) = blood type AB
\(I^{a} I^{o}\) = blood type A
\(I^{b} I^{o}\) = blood type B
