Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mitosis y meiosis
Answer:
la vida no podría continuar sin los procesos de división celular
Explanation:
La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.

Which two words describe the grass in this food chain?
A. Autotroph, primary consumer
B. Heterotroph, producer
C. Heterotroph, primary consumer
D. Autotroph, producer
Answer: Autotroph, producer
Explanation: The grass gets eaten by primary consumer starting the food chain
In a food chain, the grass is referred to as an autotroph and producer. Therefore, option D is correct.
What are autotrophs?An organism is referred to as an autotroph or primary producer when it uses carbon from simple substances like carbon dioxide to create complex organic compounds. These creatures often obtain their energy from inorganic chemical reactions or light.
Both plants like blue-green algae and microorganisms like cyanobacteria are assumed to be autotrophs. Most plants are autotrophs because they create their own food through photosynthesis. But there are always exceptions to the norm. Some plants are parasitic and non-photosynthetic, getting their nutrition from a host.
Thus, the grass in a food chain is described as autotroph and producer. Therefore, option D is correct.

Base your answers to questions 14 and 15 on the information in the diagram below and on your knowledge of biology. A) Finches with crushing bills eat only animals for food. B) Finches that eat animals always have larger beaks than finches that eat plants. C) Finches with grasping bills usually eat animals for food. D) Finches that eat plants all have very large beaks. 14. Based on the information in the chart, which statement is correct
Answer:
D) Finches that eat plants all have very large beaks.
Explanation:
Finches that eat plants have very large beaks because plants are big in size which can only be eaten with large beak. Those finches that lives in the environment having nuts and seeds having large beaks due to the big size of seeds and plant parts so that's why we can say that finches who feeds on plants parts have larger beaks as compared to those finches who feeds on insects.

I'm doing the fresh fruit vs canned fruit experiment and if I prepared the fruit a different way would it effect the gelatin
Answer:
How the gelatin is prepared can affect the result.
Explanation:
To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.

Course Activity: Human Effects on Ocean Ecosystems:Writing a Research Paper
In this activity, you will prepare a 1,000- to 1,250-word research paper about the effects of human activity on ocean ecosystems. You will focus on one particular human activity that has a negative effect on the ecosystem. You’ll also compare and contrast at least three existing solutions to prevent or manage the problem. The human activity you choose should be specific, be realistic, and have predictable effects on the ecosystem. For example, deforestation is a specific human activity that has a negative effect on forest ecosystems. At the end of the paper, you will write a one- to two-paragraph proposal describing a program to educate citizens on this problem and encourage them to do their part to prevent it.

1. List and describe the five kingdoms of life.
Who developed this system?
What is the basis for the divisions?
Why is it important to the study of biology?
Answer:
1. animal kingdom: a basic group of natural objects that includes all living and extinct animals compare mineral kingdom, plant kingdom. 2.plant kingdom: Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize. The process of photosynthesis uses chlorophyll, which is located in organelles called chloroplasts. 3. Fungi kingdom: Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi. The organisms found in Kingdom fungi contain a cell wall and are omnipresent. They are classified as heterotrophs among the living organisms. 4. protist kingdom: The protist kingdom is a classification that includes a diverse group of eukaryotic organisms. Typically, protists reproduce asexually via mitosis and range from unicellular to multicellular organisms. 5. monera kingdom:
Explanation:
2.Carl Linnaeus Carl Linnaeus (1707–1778) laid the foundations for modern biological nomenclature, now regulated by the Nomenclature Codes, in 1735. He distinguished two kingdoms of living things: Regnum Animale ('animal kingdom') and Regnum Vegetabile ('vegetable kingdom', for plants).
3. The largest category in this system is called kingdom, and has five subdivisions: Animalia, Plantae, Fungi, Monera and Protista. All known organisms fall into one of these large categories.
4. The living organisms are divided into five different kingdoms – Protista, Fungi, Plantae, Animalia, and Monera on the basis of their characteristics such as cell structure, mode of nutrition, mode of reproduction and body organization.
Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.
Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.
How does light affect aquatic life?Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.
Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.
The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.
Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.
