Answer: Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

RNA contains instructions to make a specific protein and is produced from genetic information in the nucleus of the cell. This process is called translation. Therefore, option C is correct.
What is translation?The translation is the creation of a polypeptide chain from mRNA codons. The process is broken down into four steps: tRNA charging, initiation, elongation, and termination. mRNA is made from DNA by transcription, and then protein is formed from mRNA by translation.
The process of translating mRNA into the chain of amino acids that makes up the produced protein occurs in ribosomes in the cytoplasm of the cell.

1. What causes community resilience?
Answer:
Community resilience is the sustained ability of a community to use available resources to respond to, withstand, and recover from adverse situations. This allows for the adaptation and growth of a community after disaster strikes. Communities that are resilient are able to minimize any disaster, making the return to normal life as effortless as possible. By implementing a community resilience plan, a community can come together and overcome any disaster, while rebuilding physically and economically.

Reproducción sexual
La reproducción sexual consisten en la ___________ de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los ___________ son células especializadas que se forman por un proceso __________ y tiene en su núcleo la mitad de la información __________ de un organismo, por lo que reciben el nombre de células ___________ de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la ___________ genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son ___________ a ellos. El proceso en el que se une las células sexuales se le conoce como ___________. En los animales esta pude ser interna o externa.
Answer:
La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.
Explanation:
Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).
Explain how vaccinations can protect you from infectious diseases such as measles and chicken pox.
Answer:
Look at explanation.
Explanation:
So, most vaccines help us against infectious diseases by inserting a weak or dead version of the virus. This makes your body create antibodies to fight against the virus. So most vaccines prepare your body to be able to TRY and fight the virus by giving you a small taste of what its like.

Which type of fuel produces greenhouse gases?
A. Hydroelectric
B. Wind
C. Biomass
D. Nuclear
The type of fuel produces greenhouse gases is the Biomass fuels.
Who are fossil fuels?Fossil fuels include oil and its derivatives, coal and natural gas, all formed by the decomposition of living organisms.
The main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.
in this case, biomass fuels are plants, animals and their derivatives are biomass. Use as fuel can be made from its raw form, such as wood, agricultural products and residues, forest residues, livestock residues, animal excrement and garbage. In other words, are fossil fuels and podruces greenhouse gases.

what are the merit of
indigenous education
Answer:
It was a way to protect, preserve and develop traditional indigenous skills and cultures. Education was a significant step towards empowering indigenous peoples to participate more fully in their communities. It was an indispensable asset to attain freedom and social justice.
Answer:
The core of indigenous education in Africa focused on providing each individual in the community with knowledge, practical skills and attitudes in order to prepare them to for his/her role in the society. It is a holistic system, in which apprenticeship, story telling, proverbs and myths played an important role. Traditional education developed in the ‘learners’ a sense of obligation towards the community and made learners to appreciate the history, language,customs and values of the tribal group, keeping in touch with their heritage, their cultural roots. Western education alienates young Africans from their cultural heritage.

Oxygen rich blood returns from the lungs to the heart. Which 2 systems are most directly involved in this process.
Respiratory and circulatory
Excretory and digestive
Circulatory and excretory
Digestive and respiratory
Answer:
Respiratory and circulatory
Explanation:
The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide. Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs.
The two systems which are most directly involved in this process are respiratory and circulatory systems.
What do you mean by oxygen-rich blood?In the lungs, oxygen is put into the blood, and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.
During the whole process of breathing, the respiratory and circulatory systems play a major role in the separation of oxygen-rich and oxygen-poor blood.
Therefore, the two systems which are most directly involved in this process are the the respiratory and the circulatory systems.
