fill in the blanks to complete the concept map for the process of translation
Answer:RNA code for Amino Acids that make Proteins through the process of translation
Explanation:
During translation, tRNA recognizes the mRNA codons, complements them, and add the correct amino acid to the growing protein. CODON and PROTEIN are the missing words.
--------------------------------------------------------------------------
Protein synthesis
Occurs in two steps. Transcription and translation.
Transcription ⇒ mRNA syntheis
The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation:
⇒ Cytoplasm stage
• Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
• Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.
• Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
• While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
→ mRNA is composed of different codons.
→ Each codon is a chort sequence of
three nucleotides that codes for one amino acid.
→ When tRNA molecules recognize these
sequencies, they add the correct amino
acid to the growing protein.
⇒ Protein synthesis ends when the proteins passes through the Endoplasmic Reticulum and the Golgi complex for their final folding process.

Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.

Which structure separates an animal cell from its surrounding environment? (1 point) 1 Golgi apparatus 2 plasma membrane 3 nuclear membrane 4 central vacuole
Answer:
2) plasma membrane
Explanation:
The structure that separates the cell from its surrounding is plasma membrane, the correct option is 2.
What is plasma membrane?The plasma membrane, also renowned as the cell membrane, is the membrane located outside all cells that distinguishes the cell's interior from its surroundings.
A cell wall is attached to the plasma membrane on the outer of the plasma membrane of bacterial and plant cells.
The semi-fluid living matter in the cell is called protoplasm or in other words simply plasm. This living matter, or one can say plasm, is contained within the plasma membrane, a biological membrane.
Lipids which are phospholipids and cholesterol, proteins, and carbohydrate groups attached to some of the lipids as well as proteins are the primary components of the plasma membrane.
A phospholipid is a sort of lipid that is created by glycerol, two fatty acid tails, and a phosphate-linked head group.
Thus, the correct option is 2.

Select TWO processes that are MOST LIKELY to cause the variation in bird beak size traits within this
population
A. Asexual reproduction
B.Hibernation
C.Sexual reproduction
D.Migration
E.Mutation
The two processes that are most likely to cause the variation in bird beak size traits are ; ( C and E )
sexual reproduction ( C ) Mutation ( E )The Random Mutation occurring in birds due to the environmental factors and food availability in an area will to lead to the varying changes seen in the size of beaks of the bird within a population. long beaks are used to pick out food from cactus plants while short strong beaks are used to pick out food underground.
Sexual reproduction between birds with varying genes will lead to the formation of varying beak sizes traits seen within a given bird population.
Hence we can conclude that the two processes that are most likely to cause variation in bird beak size are ; sexual reproduction and mutation.

Which of the following is not a possible benefit of biodiversity?
a
A higher number of species in a food web creates a more stable ecosystem.
b
A greater variety of predators indicates that fewer prey survive within the ecosystem.
c
A greater number of plant species provide more available food for primary consumers.
d
A variety of habitats within an ecosystem supports a greater number of species.
Answer:
b
Explanation:
because the more predators less prey and less organisms
It seems unlikely that biodiversity will result in fewer prey animals surviving in the environment due to the diversity of predators. So, the correct option is B.
What is Biodiversity?The variety of all living things and how they interact with one another and the environment are referred to as biodiversity. Along with species diversity both inside and between them, this also refers to ecosystem and landscape diversity.
Because it helps ecosystems function and provide services like pollination, nutrient cycling, or climate management, biodiversity is significant. For human communities, it also has significant cultural, social, and economic importance.
The range and variety of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the levels of genes, species, and ecosystems is called biodiversity.
Therefore, the correct option is B.
