What is the main difference between food chains and food webs? (1 point)
o Food chains focus on energy transfers, but food webs do not.
o Food webs do not show connections between animals like food chains.
o Food chains focus on the internal energy cycles of animals, unlike food webs.
O Food webs are more complex than simple food chains
Answer:
The answer is D: Food webs are more complex than simple food chains.
Explanation:
A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.
Hope this helps!! ;)
Food webs are more complex than simple food chains.
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem.

The atmosphere is made up of several layers of air. The bottom two layers are the troposphere and the stratosphere. How does the troposphere differ from the stratosphere?
A.
The troposphere has a lower air pressure than the stratosphere.
B.
The troposphere contains more ozone molecules than the stratosphere.
C.
The troposphere is much warmer than the stratosphere.
D.
The troposphere contains less moisture than the stratosphere.
Answer:
C. The troposphere is much warmer than the stratosphere.
Explanation:
The atmosphere, which comprises of all the gases on the Earth, consists of five different layers namely: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The TROPOSPHERE is the lowest layer of the atmosphere, followed by the STRATOSPHERE.
The troposphere differs from the stratosphere in the sense that:
- The troposphere is much warmer than the stratosphere
- The stratosphere contains majority of the ozone, hence, it it termed OZONE LAYER.
- The stratosphere has a lower air pressure and density than the troposphere.

All of the offspring will be tall, we would expect that all 1064 seeds produced would be pure tall. This means that the answer is c. 532, since 1064/2 = 532.
What is hybridization?Hybridization is the process of breeding two individuals of different varieties, strains, or species to produce offspring with traits from both parents. This can occur naturally, through the cross-pollination of flowers or the natural mating of animals, or it can be artificially induced by humans through techniques such as selective breeding or genetic engineering.
Hybridization is often used in agriculture and horticulture to produce crops or ornamental plants with desirable traits from different varieties or species. For example, hybrid corn was developed by crossing different varieties of corn to produce plants with improved yields, disease resistance, and other beneficial traits. In animal breeding, hybridization is used to produce animals with specific characteristics, such as hybrid dogs that have traits from different purebred parent breeds.
Hybridization can also occur in nature when two different species come into contact and are able to breed. This can lead to the creation of hybrid species, which are offspring that have characteristics of both parent species. Hybridization can sometimes lead to the creation of new and unique species, but it can also cause problems, such as the introduction of invasive species or the erosion of genetic diversity.

Descrlbe the relationshlp among the agents of disease, the Infectious dose, and the health of
a host.
Answer:
The number of pathogens that are required to infect a host, termed infective dose, varies dramatically across pathogen species. It has recently been predicted that infective dose will depend upon the mode of action of the molecules that pathogens use to facilitate their infection. Specifically, pathogens which use locally acting molecules will require a lower infective dose than pathogens that use distantly acting molecules. Furthermore, it has also been predicted that pathogens with distantly acting immune modulators may be more virulent because they have a large number of cells in the inoculums, which will cause more harm to host cells. We formally test these predictions for the first time using data on 43 different human pathogens from a range of taxonomic groups with diverse life-histories. We found that pathogens using local action do have lower infective doses, but are not less virulent than those using distant action. Instead, we found that virulence was negatively correlated with infective dose, and higher in pathogens infecting wounded skin, compared with those ingested or inhaled. More generally, our results show that broad-scale comparative analyses can explain variation in parasite traits such as infective dose and virulence, whilst highlighting the importance of mechanistic details.

During reproduction plant might experience absence of pollinators or presence of low temperature
Explanation:
Following can be the problems a plant might encounter during reproduction
Presence of Low temperature for long time: Due to presence of low temperature during the reproduction of plants for long period of time it will break its dormancy and freeze the blossom or developing fruitAbsence of pollinators: As e know pollinators play a vital role in reproduction. In the absence of Pollinators (i.e., beans) plants are not able to exchange the nectar carryingPlant reproduction takes place through the asexual and sexual process called pollination. They can either self-pollinate or cross-pollinate.
Reproduction needs the fusing of both the male and female gametes and fuse to male the seed that bear the fruit. During reproduction, the plants may face a lack of pollen grains and the presence of low temperature.Learn more about the two problems a plant might encounter during reproduction.

Ariana is trying to complete her flashcards for an upcoming quiz on photosynthesis and cellular respiration. On the front of each card she has written the reactants, and on the back she is writing the products. Her photosynthesis card is complete, but she is missing the back of her cellular respiration card. She asks her teacher what infomation she is missing. Which statement explains where Ariana's teacher will direct her to for help? The teacher will direct her to the anaerobic respiration card because they have identical products. The teacher will direct her to the back of the photosynthesis card because the two processes are identical. The teacher will direct her to the front of the cellular respiration card because cellular respiration has the same products and reactants. The teacher will direct her to the front of the photosynthesis card because photosynthesis reactants are the products of cellular respiration.
Answer:
The teacher will direct her to the front of the photosynthesis card because photosynthesis reactants are the products of cellular respiration.
Explanation:
Cellular respiration is an aerobic process in which energy is released by breaking down glucose ( C6H12O6 ) and other molecules.
Photosynthesis is the process in which plants make their own food in the presence of sunlight by utilizing water (H2O) and carbon dioxide (CO2) and convert it into oxygen (O2) and glucose (C6H12O6 ).
equation of cellular respiration is: C6H12O6 (glucose) + 6O2 (oxygen) => 6CO2 (carbon dioxide) + 6H2O (water) + energy
equation of Photosynthesis: 6CO2 (carbon dioxide) + 6H2O (water) +energy => C6H12O6 (glucose) + 6O2 (oxygen)
Hence, cellular respiration is a reverse reaction of photosynthesis and the photosynthesis reactants are the products of cellular respiration.
