Vesicles became enclosed by a membrane, thus becoming organelles for larger cells.
Vesicles containing amino acids fused to form nucleotides, RNA, and DNA.
Vesicles surrounded organic compounds and catalyzed reactions to form macromolecules.
Vesicles that contained self-replicating RNA grew, split, and passed their RNA to daughters.
Answer:
DNA can store genetic information and most likely appeared before RNA.
Explanation:
Answer:
Vesicles that contained self-replicating RNA grew, split, and passed their RNA to daughters.
Explanation:
RNA played role in protein synthesis and also created its own catalyst.

Define the meaning of the phrase entry requirements to higher education institutions and state four reasons why knowing the entry requirements is important
Answer:
Requirements needed by the students for the admission.
Explanation:
Entry requirements refers to the requirement needed by the students for the admission in the college or university. Knowing entry requirements is important because the university allows only those students who are eligible for the course. It provides information about the criteria on which students are selected for the admission. Due to these requirements, the students work harder and do more study to achieve the requirements that is necessary for the admission. Knowing the entry requirements will help students to collect or achieve the necessary things.

Answer:
a
Explanation:
A private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem.
can someone please write an explanation that describes the impact of the Burmese python on the Everglades?
Claim:
Evidence:
Reasoning:
Answer:
Claim:
The increase in the population of the Burmese python in Everglades is affecting the ecosystem of said area. They are an invasive species.
Evidence:
From 1994 to 2007, the Burmese python population increased from a small number below 50 species to more than 250 by 2007. As the Burmese population increased, the mammals' population in Everglades decreased significantly and even had extincted some species. For example, from 1993 to 1999, there were 64 white-tailed deer and five red foxes, and grey foxes. Between 2003 and 2011, there were 24 white-tailed deers and 0 foxes. Overall, there is a decrease in all mammals.
Reasoning:
The increasing number of Burmese Pythons due to the release of them by pet owners and due to the destructions of a private reptile breeding facility left a high number of pythons in the wild. As a consequence, these pythons ate other animals producing an imbalance in the Everglades ecosystem. Owing to its large number and how they are harming the ecosystem, they are considered an invasive species.
Explanation:
After analyzing the information, the claim is that the increasing population of pythons harms the Everglades' ecosystem.
The evidence that supports the claim is present in the graphics, where we can see how the population of this reptile grew over the years, and the mammals' population decreased. There is specific information about the reduction in the number of mammals in the area, such as the raccoon, foxes, rabbits, etc.
After presenting the evidence, the reasoning that we can make is that the pythons are killing the other animals in Everglades. Also, we can see that they are not a native species from the area since they were released by pet owners and by a breeding facility by accident. The fact that they are harming the Everglades' ecosystem and that they are not native species makes them an invasive species.

Induction of peripheral tolerance in T cells: Please choose the correct answer from the following choices, and then select the submit answer button. can be caused by interaction with MHC/peptide in the absence of costimulation. can be caused by costimulation in the absence of MHC/peptide. usually leads to apoptosis. The first and third answers describe this form of induction. The second and third answers describe this form of induction.
Answer:
can be caused by interaction with MHC/peptide in the absence of costimulation
Explanation:
T cells represent a class of white blood cells (lymphocytes) that have a major role in the adaptive immunity of the organism against specific pathogens. Peripheral tolerance is a type of immunological tolerance aimed at ensuring B and T cells that escaped from the central tolerance mechanism do not produce autoimmune diseases. Some populations of lymph node cells can induce peripheral tolerance in T helper cells (Th cells, CD4+ cells) by the presentation of peptide-MHCII (major histocompatibility complex type II) complexes acquired from dendritic cells. These dendritic cells are antigen-presenting cells that play a key role in adaptive immunity, which are well-known to induce CD4 and CD8 T cell tolerance in response to antigens (peptides/proteins).

Que tipo de procariotas crees que podrían sobrevivir a un viaje por el espacio? Explica. ayuda pliis
Answer:
bacterias extremófilas
Explanation:
Los organismos extremófilos son aquellos capaces de vivir en condiciones extremas. Los extremófilos pueden ser tanto procariotas (arqueas y bacteria) como eucariotas (hongos, plantas, animales, etc). Algunos ejemplos interesantes de bacteria extremófilas capaces de sobrevivir en condiciones extremas como las que se encuentran en el espacio incluyen:
1- Deinococcus radiodurans, la cual es una bacteria capaz de resistir grandes dosis de radiación.
2- Thermus aquaticus, una bacteria capaz de vivir a temperaturas entre 50 y 80 °C. Esta bacteria produce una ADN polimerasa termoestable que ha sido utilizada para la reacción en Cadena de la Polimerasa (PCR)
3- Polaromonas vacuolata, una bacteria capaz de desarrollarse completamente sin problemas a temperaturas muy bajas. (entre 4 °C a 0 °C).

Explain the consequences of a base substitution mutation in relation to the processes of
transcription and translation.
Answer:
A base substitution is when the base in the DNA molecules is replaced with another base.
Explanation:
This substitution changes the base sequence of mRNA during transcription and in translation the amino acid sequence coded for by the mRNA will have a mistake in it because of its change in base
