Comparing Asexual Vs. Response To Environment

The actual word homeostasis means "steady state". Homeostasis describes how the body regulates its process to keep its internal conditions as stable as possible. Homeostasis is

Homeostasis is the maintenance of a constant internal environment. The maintenance of homeostasis can occur through the nervous system or through chemical stimulation and changes are achieved and controlled by the homeostasis regulation mechanisms

Homeostasis is when a livening system has the ability to keep an internal balance. The internal balance includes body temperature, digestion, and fighting of sickness.

Asexual reproduction is one parent reproducing an offspring that are genetically alike. The purpose of asexual reproduction is so that the reproductive process can go faster without any mistakes. Sexual reproduction is a combination of genetics from the patents to reproduce an offspring. The purpose of sexual reproduction is so that evolution can take place from the organism. The animal focus today is the desert grassland whiptail. The whiptail tail uses asexual reproduction. This whiptail uses the more beneficial reproduction because fertilization is not needed, so only one parent is involved. Also, their is a high chance that the offspring would be created successfully.

Adaptation is the use of physical trait or possible behavior that the organism already has or can do. Whereas evolution is the change in the gene pool over time. Change in the gene pool includes two types it could be microevolution or macroevolution. Microevolution is defined as the generation to generation change in a population’s gene pool. Macroevolution is the accumulation of small changes that eventually lead to new species. Causes of microevolution are different from causes of macroevolution.

Homeostasis is the ability to maintain a reasonably stable internal environment that is necessary for overall function and survival of living organisms. Homeostasis is able to maintain the function of an organism by constantly adjusting to the change in conditions caused by external and internal stimuli, stabilising internal conditions suitable for survival. In humans it is carried out by the whole body, reaching every cell and organ, the body being able to detect changes in internal conditions and perform certain adjustments to account for the changes. If the body did not adjust to the changes in the internal environment the enzymes allowing functionality would stop performing prohibiting the internal organs to

- Discuss the differences between, and the advantages and disadvantages of sexual and asexual reproduction :

The main difference between asexual and sexual evolution is the process in which new individuals are created. With asexual organisms reproduction involves creating an exact copy of the parent often by itself. Sexual reproduction, on the other hand, involves meiosis and the fusion of an egg and sperm from two separate parents in order to create a new, unique individual. This causes vast differences in the evolution of each. The most prominent disadvantage of sexual evolution is the fact that two individuals of opposite sex are required to reproduce as this makes the process much slower in rate and causes vast challenges from the environment due to limited resources and parents. Asexual reproduction, however, has the ability to duplicate alone and has a extremely fast and effective rate of reproduction. The disadvantages that come with this are major as a single, harmful mutation can be passed through an entire family tree through copying errors with little to no variation. “Muller’s Ratchet” theory explains how damaging mutations in an asexual species will eventually cause the population to become extinct while a sexual species will overcome this as its offspring have variation which could keep a gene free of the harmful mutations through evolution. This variation is the main reason sexual reproduction has evolved so vastly and effectively.

Homeostasis can be defined as maintenance of balance of function and system within a constant internal and external environmental change. In the body it maintains temperature, glucose level and water within the body. A set point is a range of values that the body maintains to keep the body working in optimal standards. Negative feedback a source of information to help regulate the balance within the body.

1. Explain the essence of homeostasis. Why is it crucial for the bodily systems to maintain homeostasis? Homeostasis is the property of a system where the variable which could be a substance or temperature, is active and regulated to always remain constant. This regulation occurs inside a defined environment. A primary example is a humans body temperature. It is crucial for the bodily systems to maintain homeostasis because that is how cells and organs function properly. A primary example is when people die from extreme conditions, such as, freezing to death or dying from over heating. The body has to keep up to keep everything at equilibrium.

Asexual reproduction is a style of reproduction which offspring are formed by a single organism, and inherit the genes of one parent only; unlike sexual reproduction, which requires the genes from two parent organisms in order to create an offspring, asexual reproduction occurs when a single organism.

Homeostasis is a biological system by which tends to maintain body regulation stability while adjusting to the conditions that are excellent for survival. If homeostasis is successful then there is life and is it is not successful then there death comes in. Homeostasis is the technical term for the process of maintaining the ‘internal environment’ constant even though there are some rapid changes to its surroundings. The ‘Internal Environment’ compromises blood, body cell contents tissue fluid and all the other metabolic processes that are taking place. Homeostasis also mean ‘steady rate’. It describes the ways to which organism try to keep conditions inside the body as steady as possible. Whenever a physiological factor changes, our body will detect the change and then, by using the nervous or hormonal signals (or both), it reverses the change.

The two different types of reproduction are sexual and asexual reproduction. Types of asexual reproduction include binary fission, budding, and fragmentation. Budding is when another organism grows out of the parent cell, and separates once it’s fully developed. Fragmentation is when an organism splits into more pieces which each form into their own organism. Binary fission is when the parent cell copies its genetic material and then splits into two. The advantages of asexual reproduction are that it produces a lot of offspring, takes little energy, and is speedy. The disadvantage is that the offspring are clones.

One advantage of sexual reproduction is that it creates offspring with a high genetic variability. This will increase the diversity of species and the ecosystem since the offspring is diverse. For example, female lions give birth to about one to five cubs, and all the cubs are genetically different. This will increase the diversity of lions. Whereas asexual reproduction produces offspring that has the same genetics as its parent, which lowers the diversity rate of organisms. Another advantage of sexual reproduction is better agriculture. This is because selective breeding can apply to sexually produced organisms. Selective breeding when parent organisms are chosen to mate, which produces more desirable and better plants and animals. An example of selective breeding is corn. Corn used to be much smaller, and had fewer rows of kernels, however, farmers saved kernels from good plants and planted them to create more desirable plants like corn, leading better agriculture. Asexual organisms don’t reproduce sexually, so they can’t go through selective

Asexual reproduction is different from seucal reproduction because it reproduces through mitosis which clones the cell and results in the new cells being identical to the parent cell. However, sexual reproduction takes 50% (about) of the chromosomes of each parent to create a new diploid (zygote) which creates genetic variation and could be advantageous to evolving/natural selection.
