Answer choices before the common ancestor of all extant life. after the common ancestor of all extant life but before eukaryotes split from the other domains of life. after eukaryotes split from other domains of life but before the split of multicellular animals and multicellular plants. after the split of multicellular animals and multicellular plants but before the common ancestor of chordates. after the common ancestor of chordates.
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.

Answer:
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.

Within a population of rabbits, black fur (B) is dominant over white fur (b). A scientist observes 16% white rabbits on an island. The dominant allele frequency of this population is
Answer:
Explanation:
According to hardyweinberg principle
p+q= 1
P2+2pq+q2=1
given that
Black fur =B =p(dominant allele)
White fur =b =q (recessive allele)
q2=16%
16/100=0.16
q=√0.16
q=0.4
Since p+q=1
P=1-q
P=1-0.4
P=0.6
Therefore the allele frequency for dominant organism Black fur is 0.6

Dendritic cells process antigens by
detection.
engulfment.
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.
Explanation:
Answer: Engulfment.

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
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.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.

1. Encontramos dos factores que influyen en los seres vivos como las bacterias y la cianoficeas. Es el llado factor: a. Biotico b. Abiotico c. Ecosistema d. Mutualismo
Answer:
una. Biótico b. Abiótico
Explicación:
Dos factores que influyen mucho en los seres vivos, como las bacterias y las cianofitas, son los factores bióticos y abióticos. Los factores bióticos se refieren a factores vivos del medio ambiente, como animales, plantas, hongos, bacterias y protistas, mientras que los factores abióticos se refieren a factores no vivos como el agua, el suelo, el aire, la luz solar, la temperatura y los minerales. Estos factores tienen un gran efecto en la supervivencia de estos dos organismos.

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.
Which of the following is a measure of the biodiversity of an ecosystem?
1. How is the property of compressibility of gases used in everyday life? Give an example.
Answer:
Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.
Everyday life examples:
(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.
(2) Tubes of bicycles are filled by the pumps that compress the air.
(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.
4) oxygen bottles in medical institutes for helping the patient to breathe.

Answer: Caterpillars and Meadow voles
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%
