Which statement is supported by this cladogram?
A Hippopotamuses are more closely related to cows than to javelinas.
B Toothed whales are more closely related to mouse deer than to hippopotamuses.
C Javelinas and pigs are more closely related than baleen whales and toothed whales.
D Cows and mouse deer are more closely related than javelinas and pigs.
Answer:
A Hippopotamuses are more closely related to cows than to javelinas.
Explanation:
A cladogram is a branched diagram of characteristics shared by the organisms of a group, that represents the most probable evolutive history of the linage. Cladograms reflect the phylogenetic relationships among groups through phylogenetic trees.
In the phylogenetic tree, the taxonomic groups of interest are located in the extremes of the lines called branches. The ramification point, which is also called "node" or divergence point, represents the location of the most recent common ancestor.
The common ancestor position will determine how related are two species. If they have a recent common ancestor, they are closely related to each other. On the other hand, if the common ancestor is not recent and is located far away in the tree, then the two species will be less related to each other.
A Hippopotamuses are more closely related to cows than to javelinas. TRUE. Hippopotamuses share a common more recent ancestor with cows than with javelinas. This means that the hyppopotamus is more related to cows than to javelinas. The arrows in the cladogram (attached file) show the positions of the common ancestor shared by Hippopotamuses and Cows, and the common ancestor shared by Hippopotamuses and Javelinas.
B Toothed whales are more closely related to mouse deer than to hippopotamuses. FALSE. Tooth whales are more related to the hyppopotamus. Their common ancestor is more recent than the common ancestor between toothed whales and mouse deer. The arrows in the cladogram (attached file) show the positions of the common ancestors.
C Javelinas and pigs are more closely related than baleen whales and toothed whales. FALSE. They are equally related.
D Cows and mouse deer are more closely related than javelinas and pigs.
FALSE. They are equally related.

how does a crab moves,and why
Answer:
Most crabs usually stroll on the beach by walking sideways. But crabs can also walk forward, backward and diagonally. Because crabs have stiff, jointed legs, they move faster and easier walking sideways. ... A crab walking sideways pulls itself along with one set of legs and pushes with the other.

It is commonly stated that 'plants produce oxygen during the day and carbon dioxide at night'. Explain fully the limits of this statement.
Answer:
Yes, the statement is correct. Plants respire throughout the day, while photosynthesis takes place only in the presence of sunlight. ... At night, when there is no photosynthesis, no oxygen is released. Also, CO2 produced during respiration is not used by the plants.

Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Remember hydrophilic will color those areas that "like water", think about water`s relationship with fats).
Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.
Suppose a researcher successfully produced a membrane composed of saturated triglycerides rather than from phospholipids. What characteristics would you expect the saturated triglyceride membrane to have?
A. hydrophilic molecules would easily pass through the membrane.
B. hydrophobic molecules would be attracted to the membrane.
C. the membrane would be fluid at room temperature
D. the saturated triglycerides would not form a bilayer.
Answer:
B. hydrophobic molecules would be attracted to the membrane.
D. the saturated triglycerides would not form a bilayer.
Explanation:
Triglycerides are molecules composed of a higher proportion of saturated fatty acid chains where carbons are connected by single bonds. Triglycerides are hydrophobes, i.e., they are nonpolar hydrophobic molecules. In this case, it is expected that hydrophobic molecules, including triglycerides, would be attracted through hydrophobic interactions (between water and hydrophobes). Triglycerides contribute to maintain the structure of the cell membranes by forming a lipid bilayer. Unlike phospholipids, triglycerides lack a polar group (phospholipids contain charged phosphate groups), and therefore triglycerides are unable to orient themselves in order to form a bilayer.
Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydrates in living organisms. The most important carbohydrate is glucose that is metabolized by all living cells in the first energy-yielding pathway known as glycolysis.
Use your knowledge of glucose for carbohydrate metabolism to select the term that best completes each sentence.
The glucose conversion to_________ opens anaerobic and aerobic metabolic pathways. ________in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the The TCA cycle. converts lactate to glucose and returns the glucose molecule to the muscles through
In the Cori cycle, the release of energy from_________ the process of anaerobic glycolysis.
Answer:
The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.
Explanation:
In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).
In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.
The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.
VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.
In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.
