A) Fats contain half the amount of energy than carbohydrates because they have less bonds.


B) Carbohydrates contain more energy than lipids because their bonds release more energy when broken.


C) Lipids contain more energy than carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.

The statement is false. The term species refers to a group of living organisms capable of interbreeding to produce fertile offspring, not a collection of all organisms in a certain area along with their physical environment. This latter concept is described as an ecosystem.

The statement is false. A species is not a collection of all the organisms that live in a particular place together with their physical environment. A species is a group of living organisms that can interbreed to produce fertile offspring. They share common traits and genetics. For example, all humans belong to the same species because they can interbreed and have common traits and genetics. On the other hand, the collection of all organisms that live in a particular place together with their physical environment is called an ecosystem.

Gene expression is about making mRNA which is then translated into a protein. If the mRNA that was expressed is mis-read it may or may not have an affect on gene expression. It will have a negative effect if:

1. The protein produced is required for gene expression (e.g. the DNA polymerase)

2. The protein produced is another critical protein that the cell cannot live without.

3. If the question is more about constantly misreading during translation, eventually the cell would die because the wrong proteins would be made (or not made at all).

Explanation:

Salamanders are amphibians that most closely resemble early tetrapods in body form. They have a long body with short legs and a tail, similar to early tetrapod's. Salamanders are adapted for walking and swimming, and their gait is thought to be similar to that of early tetrapod's. Unlike frogs and toads, salamanders keep their tails as adults and have moist, smooth skin.

The correct answer is C. Salamanders are amphibians that most closely resembles early tetrapod in the body form.

Salamanders are amphibians that most closely resemble early tetrapods in body form. They have a lizard-like appearance with a long tail and four limbs, which is similar to the fossil record of early tetrapods that transitioned from aquatic to terrestrial environments during the Devonian period. Frogs, snakes, and toads have evolved more specialized body forms that are less similar to these early tetrapods. Frogs have a more specialized jumping form, snakes have lost their limbs, and toads, while similar to frogs, have dry, warty skin and shorter legs. Salamanders, on the other hand, retain many of the primitive characteristics of the first vertebrates to walk on land.

A.

The mitochondria is the site of the aerobic respiration in the eukaryotic organism. The mitochondria uses the glucose and the oxygen molecules to form the carbon dioxide, water and ATP (adenosine triphosphate) molecule.

The equation for the aerobic respiration is given below:

[tex]C_{6}H_{12}O_{6}+6O_{2}\rightarrow 6CO_{2} + 6H_{2}O[/tex]

Glucose + oxygen[tex]\rightarrow[/tex]carbon dioxide + water

All the reaction takes place in the mitochondria, Hence, the givenb lanks can be filled as follows:

1. glucose

2. oxygen

3. carbon dioxide

4. water

5. ATP

B.

The process shown in the figure is aerobic respiration. In the given figure, the mitochondria is shown, the mitochondria is the site of aerobic respiration. The mitochondria obtain the glucose and the oxygen molecule present in the cytoplasm of the cell. The complete aerobic respiration takes place in three steps glycolysis, Kreb cycle and electron transport. In the glycolysis, the glucose is converted into pyruvate. In the Krebs cycle, the pyruvate is oxidised in acetyl-CoA, which undergoes a sequence of reaction giving out ATP from ADP. In the electron transport chain, the NADH as well as succinate, which is formed in the citric acid cycle or Krebs cycle are oxidized, which provides the energy to power ATP synthase (the enzyme involved in the creation of storage of ATP).

The process occurring in the mitochondria of both plants and animals, which concerns the transformation of energy and matter, can be identified as cellular respiration. This process converts glucose into ATP, a form of energy cells can effectively use. The stages of cellular respiration include Glycolysis, Krebs Cycle, and Electron Transport Chain.

The process that occurs in the mitochondria of both plants and animals is called cellular respiration. This is how cells convert the energy stored in glucose into a form that the cell can use, namely ATP (adenosine triphosphate). Essentially, the glucose molecule is broken down in the presence of oxygen to release energy. The stages of cellular respiration include Glycolysis, Krebs Cycle, and Electron Transport Chain.

In Part B of the given model, we are identifying the process that was described above. Our evidence for this is the fact that the process involves both plant and animal cells, occurs in the mitochondria, and concerns the transformation of energy and matter. The description given aligns with the process of cellular respiration.

Answer:

Deletion mutation usually takes place due to the errors in the process of DNA replication . DNA polymerase slips off on the template strand due to which that part of the DNA is not coded in the daughter strand.

It can skip from one nucleotide (point mutation) to an entire gene. Point deletion can result in frame-shift mutation if it takes place in the beginning or middle of the gene. However, if it takes place at the end of the gene then it may cause no harm.

For example, let us assume the original sequence of DNA as ATG-AGT-CGT-ATA-TAA. It will result in the formation of methionine, serine, arginine, isoleucine, and STOP codon.

Point deletion at the end of the gene results in ATG-AGC-GTA-TAT-AA sequence. Now it will code for methionine, serine, valine, and tyrosine as AA will not code for anything. Hence, the sequence of the protein remains the same.

Hence, if deletion mutation takes place at the last or stop codon of the gene then it will cause no harm or change in the protein sequence. However, if it takes place before that then it may result in frame-shift mutation and thus a mutated protein.

A deletion mutation at the end of a gene might be less detrimental than at the beginning because it generally affects less critical parts of the protein. Deletions at the beginning can cause dramatic changes in the amino acid sequence, leading to nonfunctional proteins.

When a deletion mutation occurs at the end of a gene instead of the beginning, the impact on the resultant protein might be less severe. This is because the primary structure and functional domains of the protein are often situated towards the beginning of the gene. Deletions towards the end might only affect the terminal portion of the protein, possibly leaving its critical functions intact.

In contrast, a deletion at the beginning of the gene can lead to a frameshift mutation, dramatically altering the entire amino acid sequence downstream, potentially resulting in a nonfunctional protein. For example, if the normal gene codes for a polypeptide like met-lys-phe-gly-ile-val-pro, a deletion near the start could shift the reading frame and convert the codons to code for entirely different amino acids or even a stop codon prematurely.

the answer is B. It enables water molecules to bond to each other

The most important role of hydrogen bonding between water molecules is  "it enables water molecules to bond to each other".

A hydrogen bonding is just an electrical attraction between such a hydrogen atom covalently bonded to an even more electronegative "donor" atom as well as a group and maybe another electronegative atom with a single pair of electrons.

Many chemical methods rely on hydrogen bonding. Water's unusual solvent properties are due to hydrogen bonding. Hydrogen bonds were responsible for establishing the three-dimensional organization of foldable proteins such as enzymes as well as antibodies, as they keep complementary DNA strands together.
