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
Answers
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.

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.
Answers
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.
- The troposphere contains more moisture (relative humidity) than the stratosphere.

what do oceanographers use echo-sounding devices to study?
Answers
Echo-sounding device are used by the oceanographers to study the distance and depth of the water to know how fast the sound waves travel.
What is an echo-sounding device?Echo sounding is the measure of the depths using sound waves. Echo- sounders use different frequencies of sound to find out the different things present in the seafloor. Scientists typically use echo-sounders which transmit sound at the frequency of 12 kiloHertz (kHz) to determine how far down the seafloor depth lies.
The sound waves through the device travels down through the water column until they hit the seafloor where they are reflected back up to the echo-sounder. By recording the time it takes for the sound to travel down to the seafloor level and back again, it is possible to calculate the depth of the water as we know how fast the sound travels.

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.

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.
Answers
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.
