What is the function of cholesterol in the plasma membrane?

Answers

Answer 1
This helps slightly immobilize outer surface of membrane and make it less soluble to very small water-soluble molecules that could otherwise pass through more easily in to the body.Without cholesterol,cell membrane would be the too fluid,not firm enough and too permeable to some molecules.

How might a human muscle protein differ from a horse muscle protein?

Answers

 

A Human Muscle Protein molecule is different from a horse muscle protein molecule, due to the different sequences of the amino acids present in the muscle protein of the horse, and another different amino acid sequence in the human’s body.

Answer:

The correct answer is - different amino acid sequences.

Explanation:

Human muscles and horse muscles are similar overall but due to the higher muscle activity of the horse muscles, it has more mitochondria in their cell to produce more energy.

The major difference in the human muscle protein and horse muscle protein is that they consist of different amino acid sequences in their muscle proteins. In humans, actin and myosin are muscle protein filaments that help in movement which is different in the horse in terms of the amino acid sequence of proteins.

Thus, the correct answer is - different amino acid sequences.

give examples are producers, primary consumers, secondary consumers, and decomposers

Answers

producer = tree
primary consumer = caterpillar
secondary consumer = Bird
decomposer = maggot
Final answer:

Organisms are categorized in ecosystems by their roles: producers like plants create food, herbivores (primary consumers) eat the producers, carnivores (secondary consumers) eat the primary consumers, and decomposers break down dead material and waste.

Explanation:

In many ecosystems, the various organisms are categorized based on their roles in the food chain. Producers, such as plants and phytoplankton, are at the base, creating food through photosynthesis. Primary consumers are herbivores like rabbits and deer that eat producers. Secondary consumers are usually carnivores; an example would be a snake that eats a mouse. Adding to this, decomposers, which include fungi and bacteria, break down dead material at the end of the food chain, recycling nutrients back into the ecosystem.

As an example of how these categories interact: phytoplankton (producer) is consumed by krill (primary consumer), which is then eaten by fish (secondary consumer), and finally, fish may be consumed by a shark (tertiary consumer). To complete this food chain, decomposers would break down waste and dead organisms at every trophic level, including the remains of the shark.

How does carbons high valence relate to its ability to form these large and complex biomolecules

Answers

It can bound to two or even three other carbon atoms and still form bonds to one or two other elements.
Final answer:

Carbon's high valence, which means it can form four covalent bonds, is critical to forming biomolecules. It can bond with different atoms, allowing it to create complex macromolecules like proteins and nucleic acids. Carbon's unique bonding capabilities contribute to the diversity of biological macromolecules.

Explanation:

The high valence of carbon, established by its ability to form four covalent bonds, is crucial for the formation of complex biomolecules. Carbon's bonding nature allows it to bond with atoms of different elements such as oxygen, nitrogen, hydrogen, and even with other carbon atoms. This flexibility enables carbon to form large and complex structures like straight chains, branched chains, or ring structures. As a result, carbon chains form the basic 'skeleton' for most organic molecules, including large macromolecules, such as proteins, nucleic acids (DNA and RNA), carbohydrates, and lipids. These versatile structural variations formed by carbon atom's bonding capabilities give rise to the diversity of the biological macromolecules.

Which system provides structure and support for the body? A. Digestive System B. Endocrine System C. Muscular System D. Skeletal System

Answers

Final answer:

The skeletal system, answer D, is essential for providing structure, support, and protection for the body. It consists of all the body's bones, which make up the framework supporting muscles and other tissues and enable movement in conjunction with the muscular system.

Explanation:

Which System Provides Structure and Support for the Body?

The correct answer to this question is D. Skeletal System. The skeletal system is fundamental in providing structure, support, and protection for the body's organs. It comprises all the bones in the body, including the skull, spine, ribs, and limbs. These bones serve as the framework for the body, supporting muscles and other tissues. Besides structural support, the skeletal system plays a vital role in movement by providing the rigid structure to which muscles attach and leverage to produce movement.

Though the muscular system works closely with the skeletal system to facilitate movement and provide some degree of support, it is the bones of the skeletal system that primarily bear the weight of the body and protect internal organs. The skeletal system also stores minerals such as calcium and phosphates and contains components critical for the production of blood cells.

In the cerebral cortex, _occipital_____ is to vision as _temporal_____ is to hearing

Answers

Is this a true/false?
the occipital lobe is mainly a vision processor and the temporal lobe is involved with memory/emotion/hearing/language

Final answer:

The occipital lobe is responsible for vision, while the temporal lobe is associated with hearing, memory, and certain aspects of language.

Explanation:

In the cerebral cortex, the occipital lobe is to vision as the temporal lobe is to hearing. The occipital lobe, located at the back of the brain, is primarily involved in seeing, recognizing, and identifying the visual world. This lobe is where visual processing begins. In comparison, the temporal lobe, found on the side of the head near the temples, is associated with processing auditory information through the auditory cortex. It also comprises areas important for memory, emotion, and aspects of language, such as Wernicke's area which is crucial for speech comprehension.

What are the distinguishing characteristics of a cell undergoing mitosis during the late stages of prophase?

Answers

Chromosome become visable, they are nearing equator of cell, spindle fibres begin appearing

Final answer:

In late prophase of mitosis, the cell exhibits highly condensed chromosomes, the nucleolus becomes non-visible, and the nuclear envelope disintegrates. Additionally, the centrosomes migrate to opposite ends of the cell as the mitotic spindle further develops, setting the stage for chromosome alignment in the following phase.

Explanation:

Characteristics of a Cell in Late Prophase of Mitosis

During late prophase, a stage of mitosis, several notable events occur as the cell prepares for the division of its genetic material. The chromatin condenses into visible chromosomes. The nucleolus, normally visible within the nucleus, disappears as the nuclear envelope breaks down into vesicles.

Also, the centrosomes, which had begun to move apart during early prophase, continue to migrate to opposite poles of the cell. Microtubules emanate from these centrosomes, intensifying the formation of the mitotic spindle apparatus that will capture and segregate the chromosomes.

The late stage of prophase is characterized by highly condensed chromosomes, non-visible nucleolus, and a cell that no longer has a defined nuclear envelope. The mitotic spindle is becoming more prominent and the cell is effectively setting the stage for the metaphase, where chromosomes will align at the cell's equatorial plate.

There were also water systems and sewage systems that carried water to people and carried sewage away from people who could afford it at the time. 

The Romans built aqueducts and introduced laws for protecting stored water as steps toward environmental management, improving sanitary conditions and supporting public health.

The Romans built aqueducts as a step toward environmental management. These complex structures were essential for introducing water into cities, which improved the sanitary conditions and allowed for the construction of bath houses and gymnasium-bath complexes like the Baths of Caracalla. The baths were not just for cleanliness but also provided amenities such as running tracks, gardens, and libraries, catering to a healthy lifestyle. Additionally, in 80 A.D., the Roman Senate passed laws to protect stored water to ensure it could be utilized effectively for street and sewer cleaning, reflecting early environmental legislation.
