Answer:
Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.
Explanation:
A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.
The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.

Thyroid hormone receptor (TR) regulates growth, development, and differentiation of mammals. TR contains both a domain that binds to T3, the thyroid hormone, and a separate domain that binds to DNA. Which of the following BEST explains how TR signals?
A. T3 binds to TR at the cell membrane, which then releases second messengers to regulate gene expression.
B. T3 binds to DNA at the cell membrane, which then releases second messengers to regulate gene expression.
C. T3 diffuses through the cell membrane to bind to TR, which then binds to DNA to regulate gene expression.
D. T3 diffuses through the cell membrane to bind to DNA, which then binds to TR to regulate gene expression.
Answer:
C. T3 diffuses across the cell membrane, attaches to Tr, and then binds to DNA to control gene expression.
Explanation: Thyroid hormone, as a ligand, diffuses across the plasma membrane, then searches for the nucleus TR (Thyroid receptor and RxR aie heterochimeric bind to DNA).
When Thyroid Hormone binds to the A domain of T3, Corepressor Proteins are removed, which stimulates gene transcription.

Organism X and Y live in the same environment. Organism X contracts a bacterial infection that causes its body temperature to rise to 60°C. How will this change in temperature affect enzyme activity in both organisms?
It will decrease enzyme activity in both organism X and organism Y.
It will increase enzyme activity in organism X and decrease enzyme activity in organism Y.
An increase in temperature above the optimal range will increase the reaction rate.
An increase in temperature will denature the enzyme causing a reduction in the reaction rate.
Answer:
an increase in temp will denature the enzyme causing a reduction in the reaction rate

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.
Hope it helps! :)

The type of cells that do not have a nucleus are known as?
Answer:
PROKARYOTES are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

How does meiosis differ from mitosis?
1. It reduces the amount of DNA.
2. It decreases the number of cells.
3. It increases the number of cells.

Red Blood Cells Carry Blood Away from the heart to the rest of your body/organs
Blood is taken to the lungs to become oxygenated and returned to the heart before being pumped through the body by the blood vessel called arteries.
What are the roles of different types of blood vessel ?Blood vessels are the networks of hollow tubes which involve in the transportation of blood throughout the entire body along with the delivery of nutrients.
The blood vessel Arteries are elastic in nature which transport blood away from the heart Like Pulmonary arteries transport the blood from the heart to the lungs.
Veins are elastic transport blood to the heart. There are four types of veins are pulmonary, systemic, superficial, and deep veins.
Capillaries present within the tissues of the body and transport blood from the arteries to the veins.
Sinusoids a narrow vessels present within the liver, spleen, and bone marrow, deliver blood from larger arteries to veins.

What will most likely happen if the human population continues to grow and carelessly emit gases? (L17.20)

Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth causing earthquakes.
Too many greenhouses gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing volcanic eruptions.
Too many greenhouse gases in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth's surface causing global warming.
Answer:
I think it would be the goal warming one :)
If the human population continues to grow and emit gases then this may lead to global warming. The green house gases in the atmosphere block heat and hence cause global warming. Thus, the correct option is D.
What is Global warming?Global warming is the change in climate, referring to the long-term increase in the planet's temperature. It is caused by increased concentrations of greenhouse gases in the atmosphere. This is mainly because of human activities such as burning fossil fuels, pollution, and farming.
The greenhouse gases in the atmosphere absorb the heat. They radiate this heat. Some of the heat will leave the Earth, some of it will be absorbed by greenhouse gases, and some of it will get back at the planet's surface. With the increase in the greenhouse gases, heat will stick around, warming the planet.
Further increase in the green house gases lead to melting of glaciers and increased precipitation. This will change the climatic conditions globally.
Therefore, the correct option is D.

Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).
