what cells do not respond to hormones
Answers
While all cells are exposed to hormones circulating in the bloodstream, not all cells react. Only a hormone's "target" cells, which have receptors for that hormone, will respond to its signal. When the hormone binds to its receptor, it causes a biological response within the cell.
2. Describe how body plans provide useful information yet should be interpreted cautiously as evidence of evolutionary relationships
Answers
Body plans provide useful information about evolutionary relationships, but they should be interpreted cautiously because similar body plans can evolve independently in unrelated lineages through convergent evolution.
Body plans provide useful information about the structural and functional characteristics of different groups of organisms and can be used to infer evolutionary relationships among them.
For example, similarities in body plans such as segmentation or the presence of a notochord can suggest that different groups of animals are related and share a common ancestor.
However, body plans should be interpreted cautiously as evidence of evolutionary relationships because they can be subject to convergence, where unrelated organisms evolve similar structures due to similar ecological or functional pressures.
For example, dolphins and sharks have similar streamlined body shapes, but this is not evidence of a close evolutionary relationship between them.
In addition, body plans may not reflect the true relationships among organisms because they are based on similarities in morphology and do not necessarily reflect evolutionary history.
For example, molecular data may reveal that two seemingly dissimilar groups of organisms are actually closely related, despite differences in body plans.
Therefore, while body plans provide useful information about the characteristics of different organisms, they should be used in conjunction with other lines of evidence such as molecular data to determine evolutionary relationships more accurately.

A neuron may produce more red blood cells.
A neuron may signal when and where oxygen is needed.
A red blood cell may produce more neurons.
A red blood cell may carry oxygen to the nucleus of a neuron.
Answers
Answer:
A red blood cell may carry oxygen to the nucleus of a neuron.
Explanation:
The primary function of RBC is to deliver oxygen in the bloods stream to the all the cells,tissues and organs of the body. Neurons are example of such cells .Therefore., the interrelationship is for RBC to supply oxygen to the neurons
The RBC has some adaptive feature which makes this possible. The absence of nucleus is for enough space to carry oxygen,bi-concave shape for easy penetration of tiny tissues in the body, and to have large surface area to volume ratio.
Anatomically,the blood vessels usually grow along with the neurons.In most cases they are interwoven .E.g Gial cells and the blood brain barrier. Thus this gives adequate blond supply to the neurons,by the RBC.
Conclusively,oxygen,nutrients are supplied to the neurons.
What do you think of the butterfly effect. Use at least one example.
Answers
The butterfly effect is the concept in chaos theory that small initial differences in the starting conditions of a nonlinear system can lead to vastly different outcomes in the future, and one example of the butterfly effect is weather forecasting.
What is the butterfly effect?The butterfly effect is a concept that originated in the field of chaos theory, which studies the behavior of nonlinear systems that are highly sensitive to initial conditions. The idea of the butterfly effect comes from the analogy that the flap of a butterfly's wings in one part of the world could ultimately cause a hurricane in another part of the world, due to the complex interactions and feedback loops within the Earth's atmosphere. This concept has been applied to many different fields, including physics, biology, economics, and the social sciences.

A. The green trait is the dominant trait.
B. The offspring will inherit one gene from each parent.
C. The offspring will have both green and yellow seeds.
D. Each offspring will have a unique set of alleles.
The answer is optionB
Explanation:
This question describes a monohybrid cross i.e. involving a single gene coding for seed colour in pea plant. One allele codes for green seeds and the other for yellow seeds.
Based on the question, a plant that has the same alleles for yellow seeds is crossed with another plant that has same alleles for green seeds. The offsprings produced will have two different alleles i.e. heterozygous, contributed by each parent.
Hence, the offsprings will inherit one form of the gene from each parent.

Why the preparation of apple juice at high temperature produces a clearer juice compared to at low temperature
Answers
The preparation of apple juice at high temperature produces a clearer juice because as the pulp temperature is raised to 55°C for the enzymatic depectinisation treatment.
Pectin, a part of the cell wall of fruits like apples and oranges, is broken down by the enzyme pectinase.
Commercially, pectinase is used to help with fruit juice extraction. It shouldn't be overly finely ground, agitated, or heated to more than 35 C in order to make a highly pressable mash (95 F). When using PECTINASES, the reaction and reaction time are normally 30 to 120 minutes, and the temperature range is kept mild, between 20 and 30 C. This serves in part to prevent complete protopectin hydrolysis. Protopectin binds the cells, and when it is hydrolyzed, the fruit tissue becomes more viscous, less pressable, and less robust. PECTINASE is a great addition to the mill, especially for apples with a soft texture. Pectin esterase and polygalacturonase make up a large portion of PECTINASES made for apple mashes (aka pectin glucosidase). These enzymes significantly lessen the pomace's viscosity and stickiness without influencing or lowering its protopectin content.
Pectinase releases the juice from within the cells by enzymatically dissolving the cell wall. The extracted juice is also clarified using pectinase.
hence this pectin dissolves the pectin and other compounds responsible for cloudy appearances and hence a clear juice is obtained.

which statement best describes the function of the nervous system? the nervous system signals muscle contraction but does not control gland secretion. the nervous system is arranged to receive signals by efferent pathways and to send signals by motor pathways. the nervous system incorporates information acquired from internal and external stimuli and signals a response. the nervous system consists of the brain and spinal cord, which are linked to each other by peripheral nerves.
Answers
The statement "the nervous system incorporates information acquired from internal and external stimuli and signals a response" best describes the function of the nervous system. The nervous system is responsible for coordinating and controlling all of the body's functions, including the ability to sense, think, and move.
It receives information from sensory receptors in the body and processes this information to determine an appropriate response, which is then transmitted via motor neurons to the appropriate effectors (muscles, glands, etc.) to produce an action or reaction. This process of receiving, processing, and transmitting information is fundamental to the function of the nervous system.
The other statements in the question are not entirely accurate descriptions of the function of the nervous system. For example, while the nervous system does play a role in signaling muscle contraction, it also controls gland secretion and many other functions in the body. Similarly, while the nervous system does use efferent and motor pathways to transmit signals, this is only one aspect of its overall function.
Finally, while the brain and spinal cord are important components of the nervous system, they are not the only parts, as the peripheral nerves also play a crucial role in transmitting signals throughout the body.

True/False: Founder populations start out small and will always remain small throughout their existence. O True O False
Answers
False. While founder populations do start out small, they may not always remain small throughout their existence.
Over time, these populations can grow and expand due to various factors such as reproduction, migration, and adaptation to the environment. Founder populations are small populations of individuals that colonize a new area or become isolated from the larger parent population. While founder populations do start out small, they may not always remain small throughout their existence. The founder effect can have a significant impact on the genetic diversity of the population, which may lead to changes in the frequency of certain alleles and the development of unique adaptations over time. As the population grows and evolves, it may experience genetic drift, natural selection, and gene flow, which can all influence its genetic diversity and size. Additionally, founder populations can sometimes merge with other populations, which can increase genetic diversity and population size.

these cells were treated with colchicine. in what phase were the cells frozen?
Answers
Colchicine is a medication used to treat gout and inflammation.
It can also be used to treat familial Mediterranean fever (FMF).
However, it is most commonly used to treat gout.
It works by reducing the amount of uric acid in the blood.
Colchicine works by blocking the activity of an enzyme called xanthine oxidase.
This enzyme is responsible for converting purines into uric acid.
The cells were treated with colchicine, which is a drug that inhibits microtubule polymerization.
Colchicine was used to freeze the cells in metaphase.
Metaphase is the stage of mitosis where the chromosomes are aligned at the equator of the cell and are ready to be separated into two daughter cells by the spindle fibers.
In this phase, the chromosomes are most visible and easiest to observe.
The spindle fibers attach to the centromeres of the chromosomes and pull them apart.

what term is used to describe a signaling molecule?
Answers
The term used to describe a signaling molecule is "ligand." Ligands are molecules that bind to specific receptors, initiating a cellular response.
They can be hormones, neurotransmitters, growth factors, or other chemical messengers. Ligands play a crucial role in intercellular communication and coordination within organisms. When a ligand binds to its receptor on a target cell, it triggers a signaling cascade, leading to various cellular responses such as gene expression, enzyme activation, or ion channel opening. The binding of ligands to receptors is highly specific, ensuring that the signaling molecule activates only the appropriate target cells. This specificity allows for precise and coordinated cellular responses, regulating processes like development, metabolism, immune response, and neurotransmission. Overall, ligands are essential for maintaining homeostasis and proper functioning of biological systems.
