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.

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.
How do hypothalamus and pituitary glands work together?
Answer:
The hypothalamus is responsible for maintaining the body's internal balance (homeostasis) by stimulating or inhibiting major bodily functions such as the heart rate and blood pressure, body temperature, fluid and electrolyte balance, appetite and body weight, sleep cycle and function of the gastrointestinal track. The hypothalamus is also considered the master regulator of the endocrine system; Regulatory hormones secreted by the hypothalamus are transported by the hypophyseal-portal system to the anterior and posterior pituitary, prompting the release of secondary hormones that can affect various organ functions.

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??

What kingdom is the Dandelion in?
animal
protist
fungus
plant
Answer:
D. Plant
Explanation:
Dandelion is a plant with yellow flowers. If the flower is a plant then it would be in the plant kingdom. Flowers aren't animals, nor protists. Protists are organisms that are part of the biological kingdom called the protista. These organisms are not plants, animals, bacteria, or fungi. Fungi (Fungus) are like mushrooms and other types of things like that who feed on dead organisms. Flowers don't feed on dead organisms. So that leaves the plant kingdom.

Scientists who study biogeochemical cycles often use the term fixation to describe converting an element from gaseous form in the atmosphere to solid form in the biosphere. For example, in the nitrogen cycle, bacteria are said to fix nitrogen by converting N2 gas into nitrates and nitrites in the soil that are later used to make organic macromolecules such as proteins and nucleic acids. There are many processes involved in cycling carbon, but only one is able to fix carbon from its gaseous form in the atmosphere to solid form in the biosphere. Which process performs carbon fixation
Answer:
Photosynthesis
Explanation:
Carbon fixation refers to the process by which elemental carbon in gaseous form in the atmosphere is converted to a solid form in living organisms. It is part of the larger process known as the carbon cycle. The carbon cycle is a very important cycle which involves the different steps by which carbon is exchanged between living organisms and their environment. The carbon cyclemis divided into the biological carbon cycle and the biogeochenpmical carbon cycle. The biological carbon cycle is the rapid exchange of carbon among living things while the biogeochemical cycle refers to the much slower cycle by which carbon is stored and released from carbon reservoirs in the environment.
In nature, carbon fixation occurs in the process of photosynthesis. During photosynthesis, green plant ( autotrophs) in the presence of sunlight as an energy source uses carbon present in air as carbon dioxide together with water vapour to produce organic biomolecules known as simple sugars which are also stored as starch. The products of photosynthesis are then used by heterotrophs, to return carbon in the form of carbon dioxide back to atmosphere.

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.
Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
Which pattern of inheritance would explain the different fur color in the related dogs?
polygenic inheritance
codominance
incomplete dominance
quantitative inheritance
Answer:
A
Explanation:
Just finished the quiz
Inheritance is defined as the transmission of genetic information from the parent to the offspring. The pattern of inheritance can be polygenic, incomplete, co-dominant, or quantitative.
The correct answer is:
Option A. polygenic inheritance
Polygenic inheritance is defined as the controlling of one trait by two or more genes. The phenotypic traits of an organism are influenced by one or more than one gene.
In the case of dog fur, the relative dogs have brown and tan fur that is due to polygenic inheritance. Thus, it determines the fur color of the dogs is controlled by more than one gene that can completely influence the phenotypic traits.
Therefore, the correct answer is polygenic inheritance.

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.
Answer:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.

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!
