*** will mark BRAINLIEST if answer is correct ***
Answer: Part 1: Mass of fundamental succession stars can be pretty much as low as one-10th of the mass of the sun and can be just about as high as 150 to multiple times the mass of the sun. The age of a star relies upon its mass. The temperature of a star is sufficiently high to intertwine the hydrogen inside them to frame a helium iota. Their temperature can be pretty much as high as 15-18 million kelvin.
Part 2: By a long shot the most unmistakable component is the primary arrangement (dim), which runs from the upper left (hot, glowing stars) to the base right (cool, faint stars) of the chart.

Which of earth's biomes has the least biodiversity?
grassland
coniferous forest
tundra
rainforest

It's the tundra
Explanation: I say that because the tundra, which literally means "treeless plain," is the coldest biome. Extremely low temperatures, limited precipitation, a short growth season, minimal biodiversity, and nutrients in the form of decaying organic matter are all characteristics of tundra.
A group of researchers wants to determine the most effective antibiotic for killing the disease causing bacteria E. coli. They select 5 different antibiotics and determine how many cells were killed at the end of the experiment. The dependent variable in this experiment would be
Answer:
Number of cells killed at the end of the experiment
Explanation:
In research, the dependent variable is one whose value is dependent on another variable - a variable that is supplied by the researcher during the course of the experiment which is also known as the independent variable.
In this case, since the main objective of the research was to determine the most effective antibiotic against the E. coli, the variable that is supplied by the researcher (the independent variable) is, therefore, the different antibiotics while the variable whose value varies based on which of the antibiotics is introduced is the number of dead bacterial cells.
Therefore, the dependent variable is the number of cells killed by each antibiotic.

How would you describe the development of life on Earth- from simple to
complex or complex to simple.? Glve an example.
Answer:
From simple to complex.
Explanation:
The development of life on Earth occurs from simple to complex type of organisms. At first organisms are simple body and cellular structure but with the passage of time simple organisms are evolved and turn into complex organisms. The first life that was appeared in the Earth's oceans about 3.8-billion years ago was prokaryotic organisms. For example, Bacteria are the first organism that has simple body structure and appearance but with the passage of time various different types of bacterial species are formed that have complex body structure.
Maintaining high global biodiversity is important to provide ecosystem services to humans. Describe one cultural ecosystem service provided by diverse ecosystems.
Answer:
Ecosystem services of provision or supply
Explanation:
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.
Support:Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:
→ Soil formation
→ Photosynthesis
→ Primary production
→ Nutrients cycles
→ Water cycle
Under certain circumstances, regulation services can also be considered support services.
Support service affects human beings indirectly, or direct but causing an effect in a long-term period.
Which of these factors is a disadvantage of hybrid cars?

B. They produce fewer emissions than standard cars.
C. Federal incentives reduce the initial cost.
D. Replacement batteries are expensive.
The factor that is a disadvantage of hybrid cars is that replacement batteries are expensive, which is in Option D. As hybrid cars offer many benefits such as improved fuel efficiency and reduced emissions,
What is a hybrid car?Hybrid cars use a combination of a gasoline engine and an electric motor to power the vehicle. This hybrid system allows the car to achieve better fuel efficiency and lower emissions than a traditional gasoline-powered car. However, this system requires a battery to power the electric motor, and these batteries can be expensive to replace. The cost of a hybrid battery can vary depending on the make and model of the car, but it can range from several thousand dollars to as much as $10,000 or more.
Hence, one of the factors that is a disadvantage of hybrid cars is that replacement batteries are expensive, which is in Option D.

a haploid fungus, a transversion arises in the coding region of a gene necessary for the production of the amino acid leucine. The transversion substitutes the last base in the codon UAC (encoding cysteine), resulting in the stop codon UAG. This substitution will most likely cause;
Answer:
The correct answer is - the production of a truncated (shortened) protein.
Explanation:
In this question, it is given that there is a transversion type of substitute mutation that causes the change in the coding region of a gene. By this transversion, there is a substitute in the last base of the UAC code of gene that codes for leucine amino acid to a stop codon.
As stop codon comes before the actual stop codon in the gene leads to terminate the translation of mRNA to the amino acid chain that results in shortened or truncated protein.

A stem cell that has the potential to differentiate into any cell derived from either the endoderm, ectoderm, or mesoderm lineage or into extraembryonic tissues, such as the placenta, has the property of being:
Answer:
Totipotential.
Explanation:
There are different cell potencies. A totipotent cell is a stem cell that can divide itself and differentiate in any cell that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.

A biologist grows bacterial cultures to see if there is a relationship between time and growth rate. Here are the data. Which hypothesis test would you use to see if there a relationship between growth rates and time
Answer:
Direct relationship.
Explanation:
There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.
