when are chromosomes (dna) copied?
Answer:
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.
Have a good day. :)
Answer:
Chromosome replication
Explanation:
Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

tRNA uses (anticodons/codons) to match to the mRNA.
Answer:
anticodons
Explanation:
codons are for mRNA
tRNA uses anticodons to match to the mRNA.
Which one does tRNA uses?tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.
They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.
The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

and function of organisms.
Chromosome
Answer:
- DNA is wrapped around nucleosomes and condensed into chromosomes.
- Proteins affect the traits and function of organisms.
Explanation:
Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.
Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?
Answer:
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
Its soil contains water to extract
It isn’t too cold or too hot
There is enough sunlight to use solar panels
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!
Additional info:
Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.
Searching for life on Mars
Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.

Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

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.
What organisms are capable of cellular respiration?

the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.
