A hormone may encounter a cell but not bind to it or affect its activities if the hormone
Answers
Answer:
Hormones come in contact with many cells but only affects limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.

Which organ-system carries lipids from the gastrointestinal tract to blood?
a. Respiratory system
b. Circulatory system
c. Digestive system
d. Endocrine system
Answers
The circulatory system, also known as the cardiovascular system, is responsible for carrying lipids from the gastrointestinal tract to the blood. The final answer is (b).
After the ingestion of lipids through food, they undergo digestion in the digestive system, primarily in the small intestine. During digestion, lipids are broken down into smaller molecules called fatty acids and glycerol.Once the lipids are digested and absorbed by the cells lining the small intestine, they are transported into the lymphatic system in structures called lacteals.The lymphatic system eventually merges with the bloodstream, and the lipids are then carried through the circulatory system, specifically the blood vessels, to various tissues and organs throughout the body.

according to the fluid mosaic model,plasma membrane are mainly composed of phospholipids and proteins.Explain how structures S and T play the roles in the plasma membrane,which function as a selective barrier. please help me with this question
Answers
Answer:
The plasma membrane is a thin layer of lipid molecules that surrounds the cell and separates the inside from the outside. The fluid mosaic model describes the structure of the plasma membrane as a two-layered structure of phospholipids with embedded proteins. This model explains how the structure of the plasma membrane allows it to act as a selective barrier, regulating the movement of substances in and out of the cell.
Structure S in the plasma membrane is represented by the phospholipids, which form a lipid bilayer with hydrophilic heads facing outwards and hydrophobic tails facing inwards. The hydrophilic heads are in contact with the extracellular fluid and intracellular fluid while the hydrophobic tails are in the middle of the membrane. The phospholipid bilayer provides a barrier that separates the inside and outside of the cell, restricting the movement of hydrophilic and large molecules through the membrane while allowing the passage of small and hydrophobic molecules.
Structure T represents the integral membrane proteins that are embedded in the lipid bilayer. These proteins have different functions, such as transport of molecules, cell signaling, and catalyzing chemical reactions. The proteins also contribute to the selective permeability of the membrane by regulating the movement of specific molecules in and out of the cell. For example, channels and carrier proteins regulate the movement of ions and larger molecules through the membrane while receptor proteins receive signals from the outside of the cell and relay them to the inside of the cell.
In summary, the plasma membrane is mainly composed of phospholipids and proteins according to the fluid mosaic model. The phospholipids form a lipid bilayer that acts as a barrier, while the proteins embedded in the bilayer regulate the selective permeability of the membrane by facilitating the movement of specific molecules in and out of the cell.

Based upon what you know, what is the flaw (error) in the logic used to support the Four Pests Campaign? Be sure to justify your answer.
Answers
Based upon what I know, the flaw in the logic used to support the Four Pests Campaign was the assumption that eradicating the targeted pests would solely result in positive outcomes.
The campaign aimed to eliminate rats, flies, mosquitoes, and sparrows, which were believed to cause significant harm to crops and public health. However, this approach did not consider the ecological consequences of removing these species. For example, the elimination of sparrows disrupted the balance in the ecosystem, leading to an explosion in the population of insects that caused even greater damage to crops.
The Four Pests Campaign underestimated the complexity of natural ecosystems and the potential negative impacts of targeting specific species. In conclusion, the flawed logic stemmed from oversimplifying the issue and failing to recognize the interconnectedness of ecosystems.
The use of pesticides also led to the destruction of other beneficial insects and birds, which further disrupted the ecosystem. In conclusion, the flaw in the logic used to support the Four Pests Campaign was the failure to recognize the delicate balance of the ecosystem and the interconnectedness of different species.
The campaign's approach was shortsighted and resulted in unintended consequences that were harmful to the environment and agriculture.

which pathogen has evolved to make its rodent host less avoidant of cats?
Answers
Toxoplasma gondii, a protozoan parasite, pathogen has evolved to make its rodent host less avoidant of cats.
Toxoplasma gondii is a parasitic pathogen that undergoes a complex life cycle involving both intermediate hosts, such as rodents, and definitive hosts, such as cats. It has been found that T. gondii has evolved mechanisms to manipulate the behavior of its intermediate hosts, making them less avoidant of cats and more likely to be preyed upon, thus completing the parasite's life cycle.
Studies have shown that T. gondii infection in rodents can lead to behavioral changes that increase their susceptibility to predation by cats. The parasite can alter the neural pathways and neurotransmitter levels in the rodent's brain, affecting their fear response and making them less cautious and more attracted to the scent of cats. This behavioral modification benefits T. gondii as it increases the chances of the parasite being transmitted to its definitive host, where it can reproduce and complete its life cycle.
The ability of T. gondii to manipulate the behavior of its intermediate hosts is an example of parasite-mediated host manipulation, where the parasite pathogen alters the behavior of its host to enhance its own survival and reproductive success.

which individual is most likely to allow a recessive lethal gene to be kept in a population over several generations? responses homozygous dominant homozygous dominant heterozygous heterozygous homozygous recessive
Answers
Individuals who are heterozygous are most likely to allow a recessive lethal gene to be kept in a population over several generations.
A recessive lethal gene is a gene that expresses itself only when it is present in a homozygous state. As a result, heterozygous individuals who possess one copy of the gene do not exhibit any symptoms or defects. An example of a recessive lethal gene is sickle cell anemia. In a population with a high frequency of the sickle cell allele, heterozygotes have a significant evolutionary advantage over homozygotes for either allele. They are not affected by the symptoms of sickle cell anemia and are resistant to the deadly effects of malaria. The following options were given: homozygous dominant, homozygous dominant, heterozygous, heterozygous, and homozygous recessive. As previously mentioned, individuals who are heterozygous are most likely to allow a recessive lethal gene to be kept in a population over several generations. Homozygous dominant individuals will not pass on the recessive gene, whereas homozygous recessive individuals will die before reproducing, eliminating the gene from the population. Therefore, the answer to this question is heterozygous.

by what mechanism does the active transport of sodium lead to osmotic flow of water across a membrane?
Answers
The mechanism by which the active transport of sodium leads to osmotic flow of water across a membrane is referred to as osmosis.
What is Active Transport?Active transport is a process in which a cell uses energy to transfer a substance through a cell membrane, typically against its concentration gradient. The transport of ions, for example, frequently involves the hydrolysis of adenosine triphosphate (ATP), which yields the energy required to move ions across the cell membrane. ATP is frequently required to push substances across the membrane against their concentration gradient, whether the substance is a protein, lipid, or other molecule. In essence, active transport is an energy-driven method of moving substances across the cell membrane.
Osmotic flow is the result of osmosis. Osmosis is the diffusion of water molecules across a semi-permeable membrane from an area of higher concentration to an area of lower concentration. Osmotic pressure is produced by the movement of water molecules from an area of higher concentration to an area of lower concentration across a semi-permeable membrane. The osmotic flow of water across a membrane occurs as a result of active transport of sodium, which creates a high concentration of sodium ions on one side of the membrane and a low concentration on the other side. This concentration gradient causes water to flow from the low concentration side to the high concentration side through the process of osmosis.

Answers
The tissue that connects the client's tibia to the femur at the knee joint is ligaments. The correct answer is D) ligaments.
Ligaments are dense bands or cords of connective tissue that connect bones to other bones, providing stability and support to joints. In the context of the knee joint, there are several ligaments that connect the tibia (shinbone) to the femur (thighbone).
One of the most important ligaments in the knee joint is the anterior cruciate ligament (ACL), which prevents the tibia from sliding too far forward relative to the femur. The posterior cruciate ligament (PCL) is another major ligament that prevents the tibia from sliding too far backward.
Additionally, there are collateral ligaments on the sides of the knee joint: the medial collateral ligament (MCL) on the inner side and the lateral collateral ligament (LCL) on the outer side. These ligaments provide stability and prevent excessive sideways movement of the knee.
While fascia (A) is a connective tissue that surrounds and separates muscles and organs, bursae (B) are fluid-filled sacs that reduce friction between tissues. Tendons (C) connect muscles to bones, not bones to bones as in the case of ligaments. Therefore, the correct answer is ligaments (D) for connecting the tibia to the femur at the knee joint.
