Explanation:
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.
Nondisjunction that occurs during meiosis II produces what?
Answer:
Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II.
When uncontrolled, the cell cycle becomes cancer. It forms lumps called..?
Answer:

Explanation: (:
Answer:
It forms lumps called tumors.
During a study session about evolution, one of your fellow students remarks "The giraffe stretched its neck while reaching for higher leaves, its offspring inherited longer necks as a result, which statement is most likely to be helpful in correcting this students misconception?
a) characteristics acquired during an organisms life are generally not passed on through genes
b) spontaneous mutations can result in the appearance of new traits
c) only favorable adaptations of survival value
d) disuse of an organ may lead to its eventual disappearance
Answer: Characteristics acquired during an organism's life are generally not passed on through genes.
Explanation:
The most common misconception between students which can be corrected is that the characteristics acquired during an organisms life are generally not passed on through the genes. Thus, the correct option is A.
What are acquired traits?Acquired traits or characteristics are the non-heritable changes in the function or structure of a living organism which is caused after birth and was absent before this. Occurrence of acquired traits could be due to disease, injury, accident, deliberate modification, variation, repeated use, or other environmental influence.
For example, the giraffe stretched its neck while reaching for the higher leaves but her children does not get a long neck by birth however this character has been fixed with time because of the repeated use of the neck for food.
Therefore, the correct option is A.

what was explained by darwins theory of biological evolution
Answer:
When Organism A has a trait that negatively impacts it, or lacks a trait which would positively impact it, then said organism perishes, and its genes are not passed onto the next generation. On the flip side, when Organism B has a trait that positively impacts it, or lacks a trait that would negatively impact it, then the organism thrives, and its genes are passed onto the next generation.
Therefore, the next generation receives genes from Organism B and does not receive genes from Organism A. So, the next generation has traits that positively impact it and lacks traits that would negatively impact it, thus evolving according to Darwin.
Explanation:
What was explained by it? Evolution. But how did it explain evolution? That is in the answer.
Suggest reasons for the color patterns of the frog and its lack of color on the ventral surface.
Answer:
To save itself.
Explanation:
The color patterns of the frog and its lack of color on the ventral surface allows the frog to protect itself from their predators because the frog changes its colour and the predators are unable to see them. The color patterns of frogs and their lack of color on the ventral surface allow frogs to escape from their predators. If the frog does not change its colour, the predators will see them and the frog will be catch by its predators and feed on them so this is the reason that frog changes colour or the presence of colour patterns.

Who ever Answer this right will get brainliest
Answer:
See Explanation
Explanation:
Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).
Antibodies are the body's natural protective mechanism against pathogens. Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.
Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.
In a sample of double stranded dna if 19% of the nitrogenous bases are guanine what percent of the nitrogenous bases are adenine
Answer:
31%
Explanation:
Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If
G = 19% then C= 19%
19% + 19% = 38%
100% - 38% = 62%
62% for A and T
Divide by 2 and you get
31%
