When a question states that the plants are "homozygous for the contrasting traits," that means that the plants will have the same letter genotype for both of their chromosomes. In other words, if we use the letter "b" as our chromosome, one plant will have the genotype "BB", and the other will have "bb." Now, there will only be on expected genotype with these, and that would be "Bb." To find this, you must put the genotypes in a punnet square and calculate the different genotypes. The big B is dominant over the little b, so in this case the offspring plant will have a heterozygous for both traits.
Answer:
Frogs and toads are carnivores, which means that they will eat meat. Small to medium sized frogs eat insects such as flies, mosquitoes, moths and dragonflies. Larger frogs will eat larger insects like grasshoppers and worms. Some large frogs will even eat small snakes, mice, baby turtles, and even other smaller frogs , which means that if one of the A ponds have fish , mosquito or any of the above then frogs are more likely to be found in that A pond ,
- The majority of species are found in moist tropical climates. Frogs fall into one of three categories depending on the habitat they are typically found in: terrestrial, arboreal or aquatic. Many frog species live in temperate climates that have winters, and hibernation during the cold months is key to their survival., so if pond A is hot and has humid climate then frog is likely to be fond in B pond
frogs = These could tolerate water of pH 3.35

Hormones because if you think about it. Vertebrates must have backbones and mammals have them. And, humans are basically mammals. And the glands secrete hormones.
Answer:
H20
Explanation:
Because without water you will die faster then without food
Answer:
1 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). ... Flooding rivers wash away soil. 2 As the global human population continues to grow, so too does our impact on the environment. The ingenuity with which our species has harnessed natural resources to fulfill our needs is dazzling.
3 Humans impact the environment through their interactions in many different ways, such as overpopulation, pollution, and the burning of fossil fuels. Human environment interactions have resulted in impacts, such as climate change, soil erosion, and air pollution. 4 All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). 5 The National Environmental Policy Act of 1969 committed the United States to sustainability, declaring it a national policy “to create and maintain conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations.”
