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.

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.

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.

Describe two problems a plant might encounter during reproduction

Answers

Answer:

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 carrying  

Plant 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.
