what are the three domains in the new system of taxonomy.
Answer:Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eucarya.According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus. All life that has a cell nucleus and eukaryotic membrane-bound organelles is included in Eukarya.

What are cellular organisms?Cellular organisms are living beings that consist of one or more cells. Cells are the basic unit of life and the building blocks of all living organisms. Cellular organisms include all living things from bacteria to complex multicellular organisms such as plants and animals.
Cells have a variety of structures and functions depending on the type of organism they belong to. In unicellular organisms, such as bacteria, a single cell performs all the functions required for life. In multicellular organisms, cells are specialized to perform different functions, such as carrying oxygen in red blood cells or detecting light in the retina of the eye.
Cellular organisms have the ability to reproduce, grow, and respond to their environment. The study of cellular organisms is fundamental to the fields of biology, medicine, and biotechnology.

A reaction that absorbs energy from the environment a reaction that requires an activation energy a reaction that releases energy into the environment a reaction that does not involve a change in energy
Answer:
Endothermic reaction
Explanation:
An endothermic reaction is a chemical reaction that takes energy from the atmosphere. It requires activation energy. An exothermic reaction is the reverse of an endothermic reaction. Reversible reactions are where the compounds will react to the initial reagents.

Al examinar la aleta de un pez primitivo, los científicos encontraron similitudes entre su estructura ósea y la de los reptiles, las aves y los mamíferos modernos. ¿Que tipos de evidencias describe este caso?
Answer:
evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)
Explanation:
En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.
What is the process of mRNA creating a protein?
In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. ... The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.
Answer:
This process is called protein synthesis, and it actually consists of two. The enzyme is ready to make a strand of mRNA with a complementary sequence of bases.
Explanation:
Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea
Answer: He performed dihybrid crosses
Explanation:
Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.
Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.
Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

5. You cross one black (Bb) mouse with one brown (bb) mouse. Complete the Punnett square to find the expected ratio of black to brown mice pups. All six mice pups in the litter have brown fur. Explain this result.
I think all the mice had brown fur due to epistasis
Explanation:
The expected results would be 50% black and 50% brown and the ratio could be 2:2. But, if epistasis occurred and the brown fur gene overshadowed the black fur gene, then all the offspring could have brown fur.
The Punnett square to find the expected ratio of black to brown mice pups is to be considered when all the mice had brown fur because to epistasis.
Completion of the Punnett square:The expected result should be 50% black and 50% brown and the ratio should be considered as the 2:2.
In the case when epistasis should be arisen and brown fur gene should be overshadowed the black.
Hence, the same should be considered.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell
Answer:
Hypotonic / moves into the cell.
Explanation:
Hope you have a nice evening.
The solution is hypotonic. Water will move into the cell.
What is hypotonic solution?A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.
As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.
