Birds and reptiles both lay hard-shelled eggs. Birds, reptiles, frogs, and fish have jaws. Birds, reptiles, and frogs have four limbs. Which cladogram shows the relationship between these organisms?

Answer:

True

Explanation:

Answer:

Adenine, Thymine, Guanine, and Cytosine

They possess complimentary paring. Meaning the one will only bind another, and will not bind with and other one

Explanation:

DNA has four types of bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine forms double hydrogen bonds with thymine, while guanine forms triple hydrogen bonds with cytosine.

DNA is called deoxyribonucleic acid. It is a polymer of nucleotides. Each nucleotide is made up of a phosphate, a pentose sugar, and a nitrogenous base. In DNA, there are four types of nitrogenous bases, such as adenine (A), guanine (G), cytosine (C), and thymine (T).

Adenine and guanine are purines and double-ringed structures. Cytosine and thymine are pyrimidines and single-ringed structures. A purine forms a bond with a pyrimidine. Adenine (A) forms a double hydrogen bond with Thymine (T), and Guanine (G) forms triple hydrogen bonds with Cytosine(C).

Hence, in DNA, four nucleotides are found: adenine (A), guanine (G), cytosine (C), and thymine (T). Adenine pairs with thymine, while guanine pairs with cytosine.

Answer:

CCTGC

Explanation:

Adenine (A) and Thymine (T) are base-pairs whilst Cytosine (C) and Guanine (G) are base-pairs as well. Although they only go in the order A-T and C-G, you will never see Adenine and Cytosine together on a DNA strand.

Answer:

D Hope this is right......

All DNA is passed from one generation to the next during reproduction. So the correct option is D.

DNA or deoxyribonucleic acid is a polynucleotide molecule. Each nucleotide of DNA is composed of one nitrogen base, one deoxyribose sugar and one phosphate group.

The nucleotides are bonded with each other by the formation of phosphodiester bonds which liberate a water molecule.

The nitrogen base in the DNA is of four types. Adenine, Thymine, Cytosine and Guanine. The DNA is present in a double-stranded form and the nitrogen base is attached to each other in both the strands with the help of hydrogen bonds.

The nitrogen bases join with each other by the base pairing rule. Adenine joins to thymine and guanine joins to cytosine.

DNA a genetic material and a hereditary material. It is responsible for the functioning of an organism and the transmission of hereditary traits from one generation to the next.

Therefore the correct option is D.

Answer:

homologous structures.

Explanation:

If two organisms look very similar during their early stages of development, this is evidence that the organisms. evolved from a common ancestor.

Answer:

No

Explanation:

The universality of the genetic code refers to how the codons for amino acids are always the same in almost all species. Amino acids have corresponding nitrogenous bases in pairs of three called a codon. so to have the same amino acids, all species would need the same nitrogenous bases.

Answer:

They can breed and produce offspring that can breed.

Explanation:

The options you were given are the following:

A species can be defined as a group of similar organisms that can reproduce and produce offspring that can produce as well. This is why the first option is the correct one.

In ecology, the term community refers to a group of populations of two or more different species that inhabit the same area. More than one species can be found in a biome and ecosystem as well, which is why the second and third options are incorrect.

Some organisms can look very similar but belong to different species. This is why the fourth option is not correct, either.

Immunity is one of the most concern topic of human health now a days. So, to maintain our immune cells throughout our lifetime, we can follow the following tips:

Eat a healthy diet: It is important to take nutrient-rich diet so that our immune system can fight against the disease causing bacteria or virus and keeps us healthy enough.

Get active: Regular exercise and keeping ourselves active keeps our muscles and body fit and provide energy to our immune cells.

Get plenty of sleep: Sleeping is one of the way to stay healthy but it should be  limited. Its important to give rest to your body so for that its important to take 6 to 7 hrs of sleep per day.

Maintain body weight: overweight can weaken our immune cells, so important to maintain our body weight with physical activity and eating a healthy diet that will keep our immune cells throughout our lifetime.

Quit smoking and other harmful habits: Smoking makes our immune cells weak and slowly our body get prone to diseases. So, to keep immune cells healthy one should quit smoking.

Answer:

A RNA polymerase separates the hydrogen bases of a gene to produce a strand of messenger RNA, which leaves to nucleus. When a ribosome attaches itself to the messenger RNA, it reads the RNA 3 bases at a time to build amino acids which are then folded into proteins.

More explained process:

Note: The description below will explain the process of “protein synthesis”, in which the mRNA (messenger RNA) takes part of.

In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids. [ For example, the bases are AUC, the corresponding amino acid will be isoleucine (Ile). Next, the tRNA molecules carry the amino acids to mRNA, reads the RNA 3 bases at a time to build an amino acid chain which are then folded into proteins.

Answer:

17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand  

18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.

19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded. This means that it is the recessive allele because people are less prone to getting straight hair, as you can see in that diagram.

Explanation:

Atoms have a neutral charge overall, which means they have an equal numbers of positively-charged protons and negatively-charged electrons. Here, an atom of arsenic with 33 electrons must also have 33 protons.

The mass of any atom is contained in its nucleus, a part made up of protons and neutrons - particles with no charge. Both protons and neutrons are exactly 1 atomic mass unit each, so to find the atomic mass of an atom, we can use the formula

(# of protons) + (# of neutrons) = atomic mass

or equivalently:

atomic mass - (# of protons) = (# of neutrons).

For arsenic, we have an atomic mass of 75 amu and 33 protons, so using our formula:

# of neutron = 75 - 33 = 42 neutrons
