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.

*** 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.

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.

Which of the following species would have the greatest chance of going extinct?(1 point)
a species with a fast reproduction rate and lots of genetic variation living in a changing environment
a species with a fast reproduction rate and lots of genetic variation living in a stable environment
a species with a slow reproduction rate and very little genetic variation living in a changing environment
a species with a slow reproduction rate and very little genetic variation living in a stable environment
Extinction of the species refers to the death of the total species from the planet. The species with a slow reproduction rate and little hereditable variability habiting changing conditions will extinct first.
What factors influences the extinction rate?Many biological factors affect the survival of the organism as they play the most crucial role in the life and death of the species. The organism's reproduction rate, genetic modification and variability affect the survival of the organism.
The species that have a high rate of reproduction and high genetic variation can survive and continue their lineage when the surrounding habitat or the environment is altered or modified as they have better traits and characters.
The species in a changing environment with slow reproducing capability and very less genetic modification and variation will reduce the survival and adaptation chances of the organism and are more likely to go extinct first compared to the other organisms.
Therefore, option c, slow reproduction and less genetic variation in the species will go extinct first.

If 10.0 mL of blood plasma has a mass of 10.279 g and contains 0.870 g of protein, what is the mass/mass percent concentration of protein in the blood plasma
Answer:
Mass/mass percent concentration means the mass of the solute/mass of the solution times 100. You know both the mass of the solute (0.870 g protein) and the mass of the solution (10.279 g solution). So divide and multiply your result by 100. (0.870 / 10.279 * 100)

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.

Which of the following criteria have to be met for a species to qualify as invasive? Endemic to the area, spreads rapidly, and displaces foreign species Introduced to a new area, spreads rapidly, and displaces other invasive species Introduced to a new area, spreads rapidly, and displaces native species Endemic to the area, spreads slowly, and displaces native species
Answer:
Introduced to a new area, spreads rapidly, and displaces native species.
Explanation:
A species is invasive when they were not present in the area before, and once that they are there, they reproduce at a high peace. The fast reproduction rate, which leads to the spread of the species in the area, causes a disbalance in the ecosystem since it eats other species, which are native because they are from that area or other species' food. As a consequence, native species die or are reduced in number because the new species invaded their habitat.
An invasive species is not endemic because they are not native to that particular area. They are always external to this one.

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.

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.

Nuclear hormone receptors are transcription factors that control gene expression by directly binding to DNA and recruiting additional proteins called coactivators and corepressors. Despite being transcription factors, they are often called receptors because they bind hormones.
Answer:
Yes.
Explanation:
Yes, Nuclear hormone receptors is also responsible for binding hormones due to presence of Ligands. Ligands bind to and activate nuclear receptors such as lipophilic substances such as endogenous hormones, vitamins A and D, and xenobiotic endocrine disruptors. The first role of Nuclear hormone receptors are the control of gene expression by directly binding to DNA and its second role is binding of hormones.
