Answer:Marsupial mammals on Australia likely evolved from a common ancestor. ... Because Australia was isolated by water for millions of years, these species were able to evolve without competition from (or exchange with) mammal species elsewhere in the world.
Explanation:
Answer:
Biogeography is the study of the geographical distributions of biological organisms. For scientists who study evolution, biogeography is often an important part of their analysis, because it provides compelling proof for their theory. This is because many geographical features, such as oceans, rivers, mountains and islands, provide barriers to species, allowing scientists to observe how they evolve separately from one another.
Explanation:
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.

One change in the body results in another change. This second change reverses the first change in order to maintain homeostasis. This sequence describes a type of
Answer:
Feedback loop
Explanation:
A feedback loop is a process in which the body tends to return to homeostasis if it deviates from normal conditions.
A feedback loop consists o three components a receptor, a control center and an effector.
There are two types of feedback loops namely, positive feedback loop and negative feedback loop.
In a negative feedback loop, the effect of the stimulus is to shut off the original stimulus or reduce its intensity, while in positive feedback loop, intensifies a change in the body's physiological condition.
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 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.

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.

Put the steps of Protein Synthesis below into the correct order.
4 points
Step 1
Step 2
Step 3
Step 4
A Protein
molecule is
produced
An mRNA
molecule is
produced
mRNA interacts
with a Ribosome
DNA interacts
with RNA
polymerase
The correct order is DNA interacts with RNA polymerase (1), the mRNA molecule is generated (2), mRNA interacts with a ribosome, and protein is produced (4).
What is transcription?Transcription (gene transcription) is the process by which a fragment of DNA is employed to generate an mRNA.
This messenger RNA (mRNA) then travels to the ribosomes in the cytoplasm to generate a protein.The process of translation refers to the protein synthesis by an mRNA template.In conclusion, the correct order is DNA interacts with RNA polymerase (1), the mRNA molecule is generated (2), mRNA interacts with a ribosome, and protein is produced (4).

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.
