what is the question

The diagram represents three sections of a cell membrane showing three different methods involved in the transport of various molecules across the membrane.

State one reason why the movement of molecules in Method C represent active transport.

Answers

Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.

Method C represents active transport because molecules/ions move AGAINST a concentration gradient.

Active transport is a type of transport across biological membranes by which cells move substances/ions against a concentration gradient.

In active transport, substances move from a region of low concentration to a region of high concentration.

Moreover, active transport requires energy to catalyze the movement of substances against a concentration gradient, which is usually provided by the hydrolysis of ATP (the energy coin of the cell).

In conclusion, Method C represents active transport because molecules/ions move AGAINST a concentration gradient.

The minimum amount of energy required to start a chemical reaction is the _____ energy.

Answers

Answer to go in the blank would be ''Activation''.

Answer:

Activation Energy

Explanation:

Activation energy is the amount of energy required to transform the substrate to a high energy state. Once the substrate is transformed into the high energy state, further changes convert it into the product.

Hence, activation energy is the energy required to start a chemical reaction. In the absence of enough amount of energy available in the system, the chemical reaction can not start.

The first organic compound is Carbohydrates. Most organisms use is as a primary fuel or their main energy source. They make up cell structures, and they're also used as stored energy in plants. Second is Lipids. If we have any other energy left over in our bodies, we typically will store that as lipids, which a lot of people think of as fats. It also makes up the cell membrane, and coats the leaves of plants to make them waterproof and also protect them from the elements. Third type are proteins. One use of proteins are chemical messengers or hormones. Proteins are useful for receptors and transport channels in order to help things move in and out of the cell. They also help to control and regulate chemical reactions. Another use is for cell structures, like your hair. the last one is for immunity. The fourth and last is Nucleic Acids. There are two main uses in organisms for nucleic acids. The first one is for protein synthesis. The other use is for our hereditary information or how we pass our traits to our offspring.

Again, frederick compares the treatment of slaves to the treatment of horses. how?

Answers

because horses are treated like tools that make things easier like slaves

Frederick Douglass, in his writings and speeches, often drew parallels between the treatment of slaves and the treatment of horses to highlight the injustice and inhumanity of slavery.

He did this by pointing out that both slaves and horses were considered property and were subject to the whims of their owners. Here are some ways in which Douglass might have made this comparison:

1. Ownership and Value: Douglass noted that both slaves and horses were bought and sold as property. Their value was determined by their physical abilities and the needs of the market, rather than being recognized as individuals with their own rights and feelings.

2. Lack of Autonomy: Neither slaves nor horses had control over their own lives. They were both subject to the will of their masters, who decided where they would live, what work they would do, and how they would be treated.

3. Physical Treatment: Douglass observed that the physical well-being of both slaves and horses was of concern only insofar as it affected their ability to work. Both were subject to physical discipline and could be punished or rewarded based on their performance.

4. Care and Maintenance: The care given to slaves and horses was often similar, as both were essential to the economic productivity of the plantation. However, this care was not given out of compassion but out of a desire to maintain valuable property.

5. Branding and Identification: Just as horses might be branded or marked to indicate ownership, slaves were often subjected to similar practices, such as being given the last name of their owner or being branded in some cases.

6. Breeding: Douglass also abhorrently pointed out that both slaves and horses were sometimes bred for specific traits, a practice that completely disregarded their humanity and reduced them to mere commodities.

7. Emotional and Psychological Impact: Douglass emphasized the emotional toll of being treated as property, noting that both slaves and horses could suffer psychologically from harsh treatment, lack of freedom, and the constant threat of separation from their families or companions.

By drawing these comparisons, Douglass used the familiar and generally accepted treatment of animals to cast a light on the immorality of treating human beings in a similar manner. He effectively used this rhetorical strategy to appeal to the moral sensibilities of his audience, many of whom might have been more accustomed to thinking about the welfare of animals than the rights of slaves.

Which anticodon pairs with the codon GAU?

A) CUA
B) GAU
C) CTA
D) GAT

Answers

The answer is A. CUA

Answer:

The correct answer would be A) CUA.

It can be explained with the help of base-pair complementarity rule. It states that adenine always base-pairs with thymine and guanine always base-pairs with cytosine.

In addition, in RNA, thymine is replaced with uracil and thus adenine base-pairs with uracil.

Anti-codon site of tRNA and codon site of mRNA are also complementary in nature.

Thus, in codon GAU, G would base-pair with C, A would base-pair with U, and U would base pair with A.

Hence, the correct anti-codon would be CUA.

An amino acid is so named because its central carbon is linked to both an amino group and a __________. hints

Answers

An amino acid is so named because its central carbon is linked to both an amino group and a carboxyl group. These groups are combined together to a single (aliphatic) carbon. The alpha position in organic chemistry the carbon directly attached to a carboxyl group, so that the amino acids in proteins are all alpha-amino acids. 
Final answer:

An amino acid's central α-carbon is bonded to an amino group, a carboxyl group, a hydrogen atom, and a unique R group or side chain. This R group is what differentiates one amino acid from another and determines their individual characteristics.

Explanation:

An amino acid is so named because its central carbon is linked to both an amino group (-NH₂) and a carboxyl group (-COOH). The central carbon, also known as the alpha (α) carbon, is bonded to four different groups making the structure of an amino acid very specific. In addition to the amino and carboxyl groups, the α-carbon is bonded to a hydrogen atom and an R group or side chain, which is unique for each amino acid and determines its properties.

Amino acids are the building blocks, or monomers, that make up proteins. The R group varies among amino acids, changing the chemical properties and giving each amino acid its identity. This is the key to the diverse range of proteins that can be built from these molecular building blocks. Understanding the structure of amino acids is crucial for grasping how proteins are formed and function.

Which organ system of the body is responsible for removing foreign substances from the blood and aiding in fat absorption?

Answers

The liver is your answer
Final answer:

The lymphatic and digestive systems, particularly the liver, are responsible for removing foreign substances from the blood and assisting in the absorption of fats. Lacteals in the small intestine absorb fats, which are then transported to the bloodstream. The liver produces bile for fat breakdown and helps to detoxify blood.

Explanation:

The Organ Systems Responsible for Foreign Substance Removal and Fat Absorption

Two organ systems are primarily responsible for removing foreign substances from the blood and aiding in fat absorption: the lymphatic system and the digestive system. The liver, as part of the digestive system, plays a pivotal role in detoxifying blood and in the digestion of fats. The liver produces bile required for the breakdown of fats in the duodenum and also processes vitamins and fatty acids. In addition, the liver synthesizes plasma proteins and filters blood.

The lymphatic system also contributes significantly to the process of fat absorption, particularly through structures known as lacteals. These are found in the villi of the small intestine and are responsible for absorbing digested lipids, which are then transported via the lymphatic vessels to the bloodstream.

The gallbladder supports the digestive system by storing and concentrating bile salts, aiding the liver in its digestive functions. Other organs, including the kidneys and spleen, are involved in filtering the blood, removing waste, and offering reservoirs for immune factors. However, it's the symbiotic functions of the liver and lymphatic system that directly handle both the removal of foreign substances from the blood and the absorption of fats.
