Explanation:
Everything is same in DNA AND RNA except that the t and u change so Thy mine becomes Uracil
Answer:
uracil
Explanation:
RNA nucleotides contain the nitrogenous bases adenine, cytosine, and guanine. However, they do not contain thymine, which is instead replaced by uracil,

A researcher crossed the F1 generation of a red snapdragon plant and white
snapdragon plant. According to the information provided, what is the phenotype
percentage of their offspring (F2)
Genotypes: RR = Red, WW = white, RW = Pink
A. Red 50% & Pink 50%
B. White 100%
C. Pink 100%
D. Red 100%
Answer:
B. white put became mix but cannot
Answer:
The answer is C
Explanation:
Based on the question telling us that we have a red snapdragon(RR) and a white one (WW)
Using a punnet square we can determine the phenotype of their off spring to be 100% Pink
Here is the Punnett Square (sorry it is kind of messy)
What organelle contain dna tightly packed into chromosomes?
Answer:
nucleus
The nucleus itself is filled with liquid (called nucleoplasm) and is similar in structure and function to cytoplasm. It is here within the nucleoplasm where chromosomes (tightly packed strands of DNA containing all our blueprints) are found.
The genetic code for one amino acid molecule consists of A) five sugar molecules B) two phosphates C) three nucleotides D) four hydrogen bonds
Answer:
c
Explanation:
The genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.
What is genetic code?
Genetic code is defined as a sequence of instructions that directs the translation of DNA into 20 amino acids, which are the basic building blocks of proteins in living cells.
It can also be defined as the collection of instructions that live cells follow to convert information stored in genetic material into proteins.
Nucleotides are defined as a three-subunit chemical molecule consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group.
It can also be defined as the fundamental building component of nucleic acids.
There are basically two types of nucleotides.
Purines - They are defined as a heterocyclic aromatic organic molecule composed of two fused rings. Adenine, guanine and hydro xanthine are purines.Pyrimidine - They are defined as a simple aromatic compounds with a six-membered ring of carbon and nitrogen atoms. Cytosine, thymine and uracil are pyrimidines.Thus, the genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.

Why do States like Arizona have less potholes than New York?
Answer:
Because New York has way more sewer system's. In 1849, following a series of deadly cholera outbreaks, the city started building sewers. New York laid 70 miles of sewers between 1850 and 1855. It then expanded the sewer network throughout the city as it grew.
Explanation:

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?
If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.
What is the genetic disorder?A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.
Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

Which processes occur in a plant embryo before it pushes out of the soil? Select three options. It uses food from the seed. Its leaves open. It produces its own food. Its roots grow downward. Its stem grows upward.
Answer:
It uses food from the seed.
Explanation:
Germination is the growth of a plant from within a seed which lead to the formation of the seedling.
It activate metabolic activity of the seed resulting in the emergence of radicle and plumule.
The seed germinate using the stored food in the embryo. Embryo are found in seeds and this is were reserved food is stored it is usually in the seed coat. plants who lack embryos produce empty seeds which never germinate. Dormant seeds do not germinate but are viable seeds this is because they require specific internal or environmental stimuli to resume growth.

Before mitosis begins, what happens during S-phase?
Answer:
the S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. in this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
in S phase, the cell synthesizes a complete copy of the DNA in its nucleus. it also duplicates a microtubule-organizing structure called the centrosome. the centrosomes help separate DNA during M phase.

Intervals of geologic time are bound by important events, like mass extinctions or the appearance of animals with hard parts. The first single-celled organisms appeared about 3.5 billion years ago. Many sea animals first show up in the Cambrian period of the Paleozoic era. That was about 545 million years. It is sometimes referred to as the Cambrian explosion because it happened relatively quickly. It lasted just over 50 million years. The next period, , the Ordovician, ended with mass extinctions of 60% of all marine invertebrates. Dinosaurs wouldn't appear for over 200 million years, during the Jurassic period in the Mesozoic era. Based on the passage, in geology, 50 million years is A an era. B not considered a very long time. C too short for any significant events to occur. D about how long dinosaurs were on the planet.
Based on the passage above, in geology, 50 million years is not considered a very long time (Option B).
What is geological time?Geological time is an expression used to describe processes that occurred on a high time scale.
Geological processes such as the emergence of species (speciation) can take millions of years.The processes on a geological time scale are difficult to commensurate from a human thinking perspective.In conclusion, based on the passage above, in geology, 50 million years is not considered a very long time (Option B).
