Answer:

True.

Explanation:

Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

Therefore, the expected phenotypic ratio would be O 2 : type A 2 : type O 3 : type O + type A 3 : type O + type B 0 : type O + type AB 0.

When it comes to human blood types, there are three alleles that determine the blood type: A, B, and O. These alleles determine the presence or absence of certain molecules called antigens on the surface of the red blood cells. A person who inherits two copies of the same allele (for example, AA or BB) will have that blood type, while someone who inherits one copy of each allele (AB) will have a different blood type.

Now, let's consider the scenario you presented: a person who is heterozygous for type A (i.e. has one copy of the A allele and one copy of the O allele) is crossed with a type O person (who has two copies of the O allele). The offspring will inherit one allele from each parent, which means they could inherit the A allele, the O allele, or a combination of both.

To determine the expected phenotypic ratio of the offspring, we can use a Punnett square. The A heterozygous parent's alleles would be written as AO, while the O parent's alleles would be OO. The possible combinations of these alleles in the offspring are:
- AO + OO = AO, OO (two different genotypes that result in the same phenotype: type A)
- OO + OO = OO (type O)
So, we have three possible genotypes among the offspring: AO, OO, and OO. These would result in the following phenotypic ratios:
- Type O: 2 (from the OO x OO cross)
- Type A: 1 (from the AO x OO cross)
- Type B: 1 (not possible in this cross)
- Type AB: 1 (not possible in this cross)
- Type O + Type A: 3 (from the AO x OO cross)

Therefore, the expected phenotypic ratio would be O 2 : type A 2 : type O 3 : type O + type A 3 : type O + type B 0 : type O + type AB 0.

The Atlantic Ocean separated Canada from Ireland approximately 83 million years ago.

If the Mid-Atlantic Ridge is spreading at a rate of 4 cm/year, then the distance between Newfoundland and Ireland would have increased by 0.04 km every 1,000 years. To determine how long ago the separation occurred, we can divide the current distance between the two locations (3,320 km) by the rate of spreading (0.04 km/1,000 years):

3,320 km ÷ 0.04 km/1,000 years = 83 million years

The Atlantic Ocean separated Canada from Ireland approximately 83 million years ago. It's important to note that this is just an estimate, as the rate of spreading along the Mid-Atlantic Ridge is not constant and has varied over time. Nonetheless, this calculation provides a rough estimate of the time frame over which the Atlantic Ocean has gradually widened.

Trees provide a heavy array of benefits. From helping us to clean our water, providing food and shelter to us, relieving our stress, and providing jobs, trees also help clean the air that we breathe.

Trees have a very crucial role in removing air pollutants from the atmosphere, while at the same time releasing oxygen and absorbing carbo di oxide.

“Trees remove carbon dioxide from the surrounding and reduce the effect of greenhouse gas effect, all span providing us with clean air to breathe."

Trees become increasingly very important in urban settings as they lend a hand with air pollution via their natural cycle of carbon absorption.

It is a pretty neat cycle and is crucially important to living systems.

Another big way that trees improve air quality is by reducing our surrounding temperatures. This helps in less use of energy-demanding air conditioning units in warmer climates.

Less demand for energy generation will result in fewer pollutants emitted, lower greenhouse gases, and ultimately a very lower level of carbon in our atmosphere.

The technique often used to identify transmembrane segments of integral proteins is d. hydropathy plot.

A hydropathy plot is a plot of the hydrophobicity of each amino acid in a protein. Hydrophobicity is a measure of how much an amino acid prefers to be in a nonpolar environment, such as the interior of a protein or a lipid bilayer. Hydrophilicity is a measure of how much an amino acid prefers to be in a polar environment, such as the surface of a protein or in water.

Transmembrane segments of integral proteins are typically composed of hydrophobic amino acids, because they need to pass through the hydrophobic lipid bilayer. Therefore, hydropathy plots can be used to identify transmembrane segments by looking for regions of the protein that are highly hydrophobic.

Answer:

DNA, codons, and proteins are all closely related as they are involved in the process of protein synthesis, which is the process by which cells produce proteins.

Explanation:

DNA contains the genetic code that determines the characteristics of an organism. The DNA code is made up of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These nucleotides form the building blocks of DNA, and they pair up in specific combinations (A with T, and C with G) to form the famous double helix structure.

However, DNA cannot directly create proteins. Instead, the information encoded in DNA is transcribed into messenger RNA (mRNA) by a process called transcription. mRNA is a molecule that carries the genetic code from the DNA to the ribosome, where proteins are synthesized.

The genetic code in DNA is read in groups of three nucleotides, called codons. Each codon corresponds to a specific amino acid, which is the building block of proteins. There are 64 possible codons, but only 20 amino acids that are used to create proteins. This means that some amino acids are coded for by more than one codon.

During translation, the ribosome reads the codons in the mRNA and matches each codon with the corresponding amino acid. This process continues until the ribosome reaches a stop codon, which signals the end of the protein.

In summary, DNA contains the genetic code, codons are groups of three nucleotides that correspond to specific amino acids, and proteins are made up of chains of amino acids. The sequence of nucleotides in DNA determines the sequence of codons in mRNA, which in turn determines the sequence of amino acids in the protein.

DNA, RNA, and protein are all closely related to each other. DNA contains all the necessary information which is required for encoding proteins. RNA contains the information from the DNA and transforms that information into proteins that perform other cellular functions.

DNA

DNA is a linear polymer that is made out of Nucleotide units. It represents a long chain where the links are found composed of individual chemical units which are called Nucleotides. DNA is responsible for forming the genetic materials of all living organisms.

RNA

RNA resembles DNA in appearance, except it contains ribose rather than Deoxyribose sugars that help in making up DNA. The RNA is made more flexible by ribose sugar.

Protein

A Protein is made up of a long chain of amino acids which are linked together. There are twenty amino acids that are commonly found in proteins. Each amino acid has a unique structure.
