Create some predictions to support the sunflowers in the future?
Answer:
The humble sunflower appears not quite of this earth. Its yellow crowned head sits atop its stalk like a green broomstick. Its seeds, arranged in a logarithmic spiral, are produced by tiny flowers called disc florets that emerge from the center of its head and radiate outward. But aside from being a biological marvel, the sunflower is also often in the scientific spotlight.
From understanding how new plant species emerge to studying “solar tracking,” which is how the flowers align themselves with the sun’s position in the sky, sunflowers are a darling in the field of science. However, researchers can only get so far in understanding a plant without detailed genetic knowledge. And after close to a decade, it has finally unfurled itself.An international consortium of 59 researchers who set their sights on the laborious task of sequencing and assembling the sunflower’s genome published their results in a 2017 study in Nature. This achievement will provide a genetic basis for understanding how the sunflower responds and adapts to different environments. “We are on the cusp of understanding sunflower adaptability,” says Loren Rieseberg, a leading sunflower expert at the University of British Columbia and a supervisor of this study.
With its genome assembled, scientists are hopeful for the next phase of the sunflower’s scientific career: as a “model crop” for studying climate adaptability in plants. This task is more complex and urgent now than ever. Climate change, according to a paper in the Annals of Botany, “will influence all aspects of plant biology over the coming decades,” posing a threat to crops and wild plants alike.

how the cells in your body are different from one another. Look at the different types of cells above, and make a list of how they differ. After you have made your list, consider why they have these differences.
Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??

3. How are frog eyes different from human eyes?
Answer:
Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.

It is the process by which plants have evolved to fill in ecological niches over time.
O
It is the process of manipulating genes in a lab to meet human needs
It is how animals are trained to do ticks
It is when humans chose beneficial traits in each generation of a spices
O It is when plants and animals chose to meet human needs
Answer:
It is when humans chose beneficial traits in each generation of a species.
Explanation:
Artificial selection is the process in which humans use animal and plant breeding to develop specific traits by choosing a particular animal or plant males and females which sexually reproduce and have offspring together. This selection is done in order to achieve a plants or animals with desired physical characteristics. This selection will leads to the production of best traits organisms for the future.

2. ¿Será importante que usemos el suelo de manera sostenible?, ¿por qué?
Yo digo que sí, porque?
3- ¿Conocemos algunas técnicas de la agricultura ecológica? ¿Cuales?
4.- ¿Crees que estas técnicas agrícolas promueven el uso sostenible del suelo?, ¿por qué?
6.- ¿Qué problemática detectamos en el caso de los productores hortofrutícolas de la región Cajamarca?, ¿Por qué crees que necesario capacitar a los agricultores con respecto a esta problemática?
7.- ¿Qué métodos se están aplicando para enfrentar el problema?
8.- ¿Estás de acuerdo que el control químico en la erradicación de la mosca de la fruta debe ser empleado de manera responsable y solo en caso de ser indispensable?, ¿por qué?
Answer:
2. Si, porque de otra manera se producirían daños el medioambiente, deforestación, y degradación del suelo, el cual es un recurso no renovable.
3. Algunos ejemplos: Rotación de cultivos, mulching, abonos orgánicos o naturales, asociaciones de cultivos.
4. Si, porque no dañan el suelo.
6. La problemática se basa en un mal uso de los recursos hídricos, la falta de riego en los cultivos.
8. Si, porque como se mencionó anteriormente, un uso indiscriminado de químicos daña al medio ambiente.
Explanation:
La agricultura consiste en la práctica de cultivar plantas y criar ganado. Dicha técnica fue clave para el desarrollo de la civilización humana mediante la cual la cría de especies domesticadas y recolección de cultivos creó alimentos que permitieron a la gente vivir en ciudades. En el siglo XX, la agricultura industrial basada en el monocultivo a gran escala llegó a dominar la producción agrícola. En la agronomía moderna, el fitomejoramiento, el uso de los productos agroquímicos como los pesticidas y fertilizantes, y los desarrollos tecnológicos han aumentado considerablemente el rendimiento de las cosechas, al tiempo que han provocado daños ecológicos y medioambientales generalizados. Las prácticas modernas de cría de animales han aumentado la producción de carne, pero han suscitado preocupación por el bienestar de los animales y los daños medioambientales. Los problemas medioambientales incluyen la contribución al calentamiento global, el agotamiento de los acuíferos, la deforestación, la resistencia a los antibióticos y el uso de hormonas de crecimiento en la producción industrial de carne. Ejemplos de esta degradación del medio ambiente incluyen a la pérdida de biodiversidad, la desertificación, la degradación del suelo y el calentamiento global, que a su vez provocan la disminución del rendimiento de las cosechas.
2. Si, porque de otra manera se producirían daños el medioambiente, deforestación, y degradación del suelo, el cual es un recurso no renovable. El uso sostenible del suelo permite conservarlo como recurso a largo plazo sin que se produzca su deterioramiento. Al no hacer uso sostenible del suelo, se pone el peligro la agricultura y a su vez la producción de alimentos. Hay que considerar que el suelo es un componente y recurso importante, un reservorio de gran parte de la biodiversidad del planeta. La vida de la flora y fauna depende del buen estado del suelo y nos resulta útil para la obtención de materia prima, siendo el área productiva del mismo limitada y bajo amenaza por los usos intensivos necesarios para satisfacer las demandas actuales. La gestión sostenible de los recursos del suelo contribuye eficazmente a prevenir el cambio climático.
3. Algunos ejemplos:
Rotación de cultivos: Consiste en la siembra sucesiva de distintos cultivos en un mismo terreno, a diferencia del monocultivo que se basa en la siembra repetida en el mismo campo. La rotación sirve para reducir la incidencia de plagas ya que se altera el ciclo de vida de los mismos, para controlar malas hierbas, para una distribución mas adecuada de nutrientes, etc.Mulching: Consiste en un método de corte en el cual la máquina cortacésped corta, se tritura, y se deja caer al suelo para que sirva como abono natural. Abonos orgánicos o naturales: Por ejemplo, estiércoles, compostas o residuos de cultivos. Permiten recuperar materia orgánica para la fijación de carbono, aumentan la actividad microbiana, favorece retención y uso de nutrientes y mejora la absorción de agua.Asociaciones de cultivos: Consiste en la siembra de dos o más especies próximas entre sí para que puedan beneficiarse la una de la otra.
4. Si, porque no dañan el suelo, no se utilizan compuestos artificiales o contaminantes y permite un crecimiento de la vegetación de forma mas natural, sin agotar sus recursos.
6. La problemática se basa en un mal uso de los recursos hídricos, la falta de riego en los cultivos. El riego consiste en brindarle agua a los cultivos para satisfacer sus necesidades hídricas que no fueron cubiertos mediante las lluvias, entonces es necesario capacitar a los agricultores para el correcto mantenimiento de los cultivos en cuanto a la proporción de agua que se les debe brindar.
8. Si, porque como se mencionó anteriormente, un uso indiscriminado de químicos daña al medio ambiente. Como así también disminuye la calidad de la fruta, afectando su sabor y sus nutrientes.
La mosca de la fruta es un insecto que produce un daño al picar el fruto, así las hembras realizan la ovoposición generando una vía de entrada de hongos y bacterias que descomponen la pulpa de la fruta. Esto hace que se produzca una maduración precoz y caída del fruto, y la consiguiente pérdida de cosecha. Es necesario controlar esto pero de manera responsable.

How do convection currents in the atmosphere form?
A Warming air expands, becomes denser, and sinks. As the air sinks, it displaces cooler, less dense air which rises
B Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down
C Cooling air contracts, becomes denser, and sinks. As the air sinks, it displaces warmer, more dense air which rises
D Cooling air contracts, becomes less dense, and rises. As the air rises, it pushes warmer, more dense air down
Answer:
B. Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down.
Explanation:
The options D and A can be eliminated because when a gas expands without gaining additional mass, it will become less dense; when a gas contracts without losing mass, it becomes more dense. Therefore, these two options conflict with the idea of density and cannot be true.
Option B is superior to Option C because convection currents are typically portrayed as beginning with the rise of warm air, which displaces/is replaced by cooler, dense air from the upper atmosphere. While Option C is similar, it describes the opposite series of events.

Dive deeper.
Explanation:
Based on that fact that you asked us the answer to an OPINION question, I suggest you go over the things you've learned this year.
In a given year, which would result in the greatest increase in population size?
A. high birth rate, high death rate, high immigration, high emigration
B. high birth rate, zero death rate, high immigration, zero emigration
C. zero birth rate, low death rate, zero immigration, low emigration
D. zero birth rate, zero death rate, low immigration, high emigration
Answer:
B. High birth rate, zero death rate, high immigration, zero emigration
Explanation:
High birth rate would mean more people being born resulting in a higher population. Zero death rate would mean that no one is dying and leaving the population. Immigration means when people come to a foreign country to live there, meaning that the population would grow. Emigration means the opposite of immigration. So that would mean that the people would be leaving your country. Resulting in a lower population. So, B is the correct answer!
Hope this helps! :3
What extra part does a bird's egg have?
I don’t understand it, if someone can explain maybe what I have to do and put into each Column or give me the answer either way would help a lot. Thank you.
Answer:
First, describe each type of evidence (eg. Molecular biology is comparing DNA sequences to determine common ancestry). Then provide examples of how those pieces of evidence support the theory of evolution. For example, for one of the comparative anatomy examples, you could say that organisms that contain similar structures most likely diverged from a common ancestor.
I hope this gets you on the right track.
