Answer:
Atoms are the smallest indivisible part of an element that can neither be created nor destroyed in a chemical reaction.
Answer:
an atom the part of an element. a particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons, and neutrons. elements can combine with each other to form molecules via chemical.

O Oxygen is released when water molecules are split.
O Carbon dioxide is used to form simple sugars.
Answer:
O ATP molecules are produced.
Explanation:
The answer is ATP molecules being produced, this happens in light and dark.

In the jar shown, a sample of various sediment was mixed with water and then mixed with water and then allowed to settle for 24 hours. The jar served as a model for what process
Answer:
Process of sedimentation.
Explanation:
The jar shows us the model of sedimentation process because all the sediments settles down in the jar due to heavy weight. The sediment can't combine chemically with water and these sediments are heavier so due to gravity they comes down and settles down at bottom of the jar, this settlement of sediments in the jar is known as the process of sedimentation.

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.

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.

List the products or outcomes for the following biological processes
1- DNA replication
2- Transcription
3-Translation
4- mitosis
5- Meiosis
Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells
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.

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.

The increase in the spread of infectious diseases are the most direct consequence of the trend in air travel. So, the correct option is A.
What are Infectious diseases?Infectious diseases are defined as disorders that are caused by organisms such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies which are generally harmless or even helpful but some organisms can cause disease. Some infectious diseases can spread from person to person.
Infectious diseases can be viral, bacterial, parasitic or fungal infections a rare group of infectious diseases known as transmissible spongiform encephalopathy (TSE). The increase in the spread of infectious diseases are the most direct consequence of the trend in air travel.

Seventy percent of the plants containing chemicals useful for cancer treatment are found only in rain forests. What type of ecosystem service do these plants provide ?
Answer: The type of ecosystem service these plants provide is PROVISIONING SERVICES.
Explanation:
Ecosystem services is defined as the activities that occurs in an ecosystem which directly or indirectly enhance the well being of humans. They are grouped into four different categories which include:
--> Regulating services
--> cultural services
--> supporting services and
--> provisioning services
The PROVISIONING SERVICES obtained from the ecosystem are any benefits or products that can be gotten from nature. These include:
--> food
--> drinking water
--> wood fuel
--> natural gas
--> medicinal resources (gotten from herbal plants which can be used to manufacture drugs for cancer treatments).
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:
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.
