population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.

How can we control bacterial diseases? Write any three measures to prevent What are
bacterial transmission.
Answer:
Bacterial diseases are treated with antibiotics. Antibiotics work by killing the harmful bacteria or by stopping them from reproducing and spreading. Different types of antibiotics are effective for treating specific types of bacteria.
Measures to take
1)Always keep your hands clean.
2)Follow tips for Coughing and sneezing without contaminating.
3) Avoid touching your nose, eyes and mouth with unwashed hands.
Bacteria are transmitted to humans through air, water, food, or living vectors. The principal modes of transmission of bacterial infection are contact, airborne, droplet, vectors, and vehicular. Preventive measures have a dramatic impact on morbidity and mortality.

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.
there are 12% cytosines in a DNA molecule , what percentage of thymines
Answer:
To calculate the percentage of thymine we need to use Chargaff's rule:
Chargaff's rules state that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
A+G=T+C
A=T
C=G
100%-(2x12)=2T
T=(100%-24%)/2
T=38%

Answer:
before the common ancestor of all extant life.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
Basically, deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
The current genetic code evolved before the common ancestor of all extant life i.e that are still in existence or alive.

immunity.
inflammation.
Answer:
Dendritic cells are the most efficient antigen-presenting cells. They take up antigens and pathogens, generate MHC-peptide complexes, migrate from the sites of antigen acquisition to secondary lymphoid organs and, finally, they physically interact with and stimulate T lymphocytes. So it would most likely be inflammation.

What type of succession starts with some soil but then goes through the 10p
steps of succession?
A. Primary Succession
B. Secondary Succession
C. Climax Community
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]
Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.
The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]
It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.
Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]
Doctors found out that you are suffering from a serious disease that can only be cured using stem cell therapy. The doctors explain that both adult and embryonic stem cells can be used in your case. Which of the 2 types would you prefer and why? Use facts about each to support your answer.
Answer:
embryonic stem cells
Explanation:
I prefer embryonic stem cells instead of adult stem cells because embryonic stem cells can be differentiate into any cell type whereas adult stem cells can't be differentiated into other cell type. Due to this feature of embryonic stem cells, it can be used for the therapy and the disease can be cured with the help of these embryonic stem cells. So I prefer embryonic stem cells due to their unique ability of differentiation into any type of cell.
