Which of the following is a true statement? Species with nucleotide sequences that match closely share a common ancestor. Adapta

tion to the environment is not related to the origin of new species. The genetic language of DNA and RNA provides evidence that contradicts evolution of finches and other birds. Molecular biologists have suggested that bacteria are more closely related to eukaryotes than are members of the domain Archaea.

Answer:

Species with nucleotide sequence that match closely share a common ancestor.

Explanation:

This is an example of common descent in the evolutionary biology where one species which lived in the earlier time becomes the common ancestor for two or more species that came later during the course of time. When we see the genetic code or sequence of nucleotides from bacteria and archea to the plants and animals we find that there is similarity in the sequences.  This provides an evidence for the universal common descent.

When the sequences of nucleotides is found to be similar in two or more organisms, such nucleotide sequences or gene sequences can be termed as Homologous Genes and these are generated due to speciation i.e. the formation of new species from an existing species. Homologous genes are said to be evolutionary related genes.

Answer:

Species with nucleotide sequences that match closely share a common ancestor. It is the true statement.

Explanation:

Every species have their specific nucleotide sequences. We can only say a different species as our ancestors when most of the nucleotide sequence will be matched with our nucleotide sequence. It is as like as DNA fingerprinting where the most matching nucleotide sequence is confirmed as their biological family member.

During metabolism the complete of one molecule of glucose results in a maximum yield if 38 molecules of
Bond [772]

During cellular respiration, which is a part of metabolism, one molecule of glucose produces a maximum yield of 38 molecules of ATP (adenosine triphosphate). ATP is the energy form that cells use to function and has also been often called the "currency" of the cells.

The whole process begins with breakdown of food by the digestive system right down to their monomer units. Carbohydrates are broken down into glucose, which is carried by blood to all cells of the body.

Each cell takes in glucose and breaks it down through the respiration process that begins with glycolysis in the cytoplasm which yields 2 ATP molecules, then onward into the mitochondria of the cell where Krebs cycle and electron transport chain processes generate 34 to 36 more molecules of ATP.

What would happen if someone stabbed your leg with a syringe full of calcium and injected the calcium directly into your muscle?
Studentka2010 [4]

Answer:

Cross-bridges would form in the absence of an action potential from a motor neuron.

Explanation:

The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.

Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, "What is the effect of mole
fomenos

Answer:

They can pass through the semi permeable membrane

Explanation:

The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through

If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.

How is genetic engineering done?
Licemer1 [7]

Answer:Genetic engineering, also called recombination DNA technology, involves the group of techniques used to cut up and join together genetic material, especially DNA from different biological species, and to introduce the resulting hybrid DNA into an organism in order to form new combinations of heritable genetic material.
