What is the definition of a hydrocarbon? (1 point)
O large molecules that are produced by living things
O a single line bonding carbon and hydrogen
O electrons shared between two different atoms
O a large chain of carbons and hydrogens bonded together
D, a large chain of carbons and hydrogens bonded together.
Hydrocarbon found naturally is mostly in crude oil that has an abundance of carbon and hydrogen. When they bond, their chains can be essentially limitless.
Hydrocarbon is a large chain of carbons and hydrogens bonded together.
WHAT IS AN HYDROCARBON:
Hydrocarbon is an organic compound made up of atoms of carbon and hydrogen elements in a long chain. As the name implies "hydrocarbon" is composed of hydro meaning hydrogen and carbon.Examples of hydrocarbon include alkane, alkene, alkyne, alcohols etc. Hydrocarbons can either be aliphatic or aromatic i.e. based on benzene ring structure

1.-La actividad consiste en que identifiques un ser vivo de tu comunidad, ubícalo en alguno de los niveles tróficos y posteriormente completa hasta obtener una cadena alimentaria. Realiza los dibujos correspondientes en tu libreta. 2.- Realiza una conclusión de lo aprendido en tu clase, por incisos, números o puntos
Answer:
1.Ratón: se ubica en el segundo nivel trófico, es un consumidor primario que se alimenta de semillas
semillas (productores)---->ratón (consumidor primario)-->serpiente(consumidor secundario) --->zorro(consumidor terciario)
2.
Hay 4 niveles tróficos.En el primer nivel se encuentran los productores.En el segundo nivel se encuentran los consumidores primarios, estos se alimentan de los productores.En el tercer nivel se encuentran los consumidores secundarios, los cuales se alimentan de los consumidores primariosEn el cuarto nivel se encuentran los consumidores terciarios que se alimentan de los consumidores secundarios.Al consumir lo que se encuentra en el nivel anterior obtienen energía para subsistir y mantener el equilibrio del ecosistema.Los niveles tróficos son los lugares que ocupan un determinado grupo de seres vivos en relación a otros por la energía que tienen y que pasan al siguiente nivel. Se ve en la cadena alimentaria, donde la energía que se obtiene de los nutrientes del nivel anterior siempre es destinada a seres mas grandes en tamaño, es decir que están en el siguiente nivel trófico y necesitan mas energía.Explanation:
El ratón es un animal herbívoro, es decir que se alimenta de plantas y hierbas, por ende se ubica en el segundo nivel trófico porque consume a los productores. Estos últimos reciben este nombre porque producen su propio alimento a diferencia del resto de los niveles en donde los seres vivos se alimentan de animales o insectos que estén en niveles inferiores.
La energía que obtiene el ratón al consumir a los productores se utiliza en el metabolismo y en las diferentes reacciones que hacen que se mantenga vivo hasta que este es consumido por otro animal transfiriendo la energía al siguiente nivel. Esta cadena sigue hasta llegar al consumidor terciario. En todos los niveles intervienen los descomponedores que degradan los restos de los seres vivos para obtener energía y nutrir la tierra, de esta forma comienzan nuevamente la cadena alimentaria.

What is a disadvantage for organisms that reproduce asexually rather than sexually?
Answer:
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilized by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage.
Explanation:
If DNA were not packed into X-shaped chromosomes, ______.
a. it would be easier to separate strands of DNA into daughter cells
b. they would look like Y chromosomes
c. the distribution of genetic material into separate daughter cells may not occur equitably
d. it would not take as long for mitosis and meiosis to occur
Answer:
c. the distribution of genetic material into separate daughter cells may not occur equitably
Explanation:
Deoxyribonucleic acid, also known as DNA, is the genetic material in living organisms. It is found in the nucleus of eukaryotic cells. The DNA is, however, found to be wrapped around certain proteins to form an X-shaped CHROMOSOME structure during the process of cell division (mitosis and meiosis).
The purpose of this shape is to ensure that the daughter cells that results from cellular division processes receives an equal copy of the DNA in each chromosome. Hence, If DNA were not packed into X-shaped chromosomes, the distribution of genetic material (DNA) into separate daughter cells may not occur equitably/equally.

How is agrovoltaics different from floatovoltaics? How are they similar?
Answer:
The differences are;
1) Agrovoltaics is the development of a piece of land for use in agriculture and electricity generation by photovoltaic panels
Flotovoltaic is the development of water bodies for the generation of solar power by mounting solar on platforms placed over a water body rather than on land
2) With agrovoltaics, solar power, breeding of livestock, and crop production can take place on the the same land which increases profitability and reduces the cost of electricity production by solar energy
3) The efficiency of the generation of power from solar energy on the agrovoltaic system is lower than the efficiency of solar power generation through the agrovoltaic system
The similarities are;
1) Both systems seek to maximize the use of space for solar power generation
2) The source of power generation is solar power in both systems
3) Both systems make use of solar panels for the generation of electricity
Explanation:
Why is it adaptive for plants to detect and respond to daily and seasonal changes?
Answer:
Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones. ... Plants also respond to daily and seasonal cycles and to disease.
Plants are known to detect and respond to the daily cycle of light and darkness. The reason why it is adaptive for plants to detect and respond to daily and seasonal changes is that plants are known to have Environmental stimuli that indicate changing seasons which therefore trigger other responses.
A lot of plants often respond to the days growing shorter in the fall where they go dormant. There are some varieties of plants that open their leaves during the day to collect sunlight and then close their leaves at night to prevent water loss.Some plant also hold their growth and development in order to survive the extreme cold and dryness of winter.

Explain how seed germination is caused by a combination of genetic and environmental factors? please help me im failing science!!
Answer:Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by how deep the seed is planted, water availability, and temperature. When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth. First the seed grows a root to access water underground. Next, the shoots, or growth above ground, begin to appear. The seed sends a shoot towards the surface, where it will grow leaves to harvest energy from the sun. The leaves continue to grow towards the light source in a process called photomorphogenesis.

4. The two major threats of burns are?
a. Loss of skin and infection
b. Dehydration and Discoloration
c. Discoloration and Loss of Skin
d. Infection and Dehydration
Answer:
A
Explanation:
Id say A because dehydration has to do with the lack of water, and we are talking about burns. Discoloration might make sense in context such as the skin around the burn was dark and discolored. But actually loosing your skin and getting an infection in that open wound sounds much worse
