Josslyn was correct for Connections Academy Grade 7 Science B Unit 1 Lesson 5 : Animal Development
thank you josslyn i got a 100% thank you.
Great! Here are the explanations for each question:
1. The sporophyte generation produces spores that grow into a(n):
To get the answer to this question, we need to understand the life cycle of plants. Plants go through an alternation of generations, which means they have both a sporophyte (produces spores) and a gametophyte (produces gametes) stage. The spores produced by the sporophyte grow into the gametophyte. Therefore, the correct answer is (a) gametophyte.
2. Placental mammals develop:
To answer this question, we need to know how mammals reproduce. Placental mammals, like humans, develop inside their mother's body. They receive nutrients and oxygen through a placenta, which connects them to the mother's circulatory system. Therefore, the correct answer is (c) inside the mother's body.
3. Angiosperms reproduce with:
To answer this question, we need to know how angiosperms (flowering plants) reproduce. Angiosperms reproduce through the production of seeds. The seeds are formed within the ovaries of flowers after fertilization. Therefore, the correct answer is (b) seeds.
4. How might blue flower petals and a landing place for bees help a plant?
To answer this question, we need to understand the relationship between plants and animals, specifically bees. Bees are attracted to flowers because they provide them with nectar, a food source. By having blue flower petals and a landing place, plants attract bees, which increases the chances of pollination. Pollination, in turn, aids in the plant's reproduction by facilitating the transfer of pollen from the stamen to the pistil. Therefore, the correct answer is (d) aid in the plant's reproduction.
5. The size of an organism is most likely determined by:
To answer this question, we need to consider the factors that influence an organism's size. Size is determined by a combination of genetic factors and environmental factors. Genes play a role in controlling growth patterns, while the environment, such as access to food and resources, can also impact an organism's size. Therefore, the correct answer is (c) its genes and its environment.
6. The fertilization process in frogs is an example of:
To answer this question, we need to understand the difference between internal and external fertilization. In frogs, the male releases sperm into the water, where it fertilizes the eggs released by the female, which also occur in the water. This process is called external fertilization because it occurs outside the body. Therefore, the correct answer is (b) external fertilization.
7. Male bowerbirds decorate their nests to:
To answer this question, we need to consider the purpose of the male bowerbirds' decoration behavior. Male bowerbirds create elaborate nests and arrange objects to attract female bowerbirds for mating. The females choose males based on the attractiveness of their nests. Therefore, the correct answer is (d) attract female bowerbirds who likely choose males with the best decorated nest.
9. Tough, protective shells developed in eggs to:
To answer this question, we need to think about the benefits of having tough, protective shells in eggs. Tough shells help prevent the embryo from drying out and also provide protection against external pressures and predators. Therefore, the correct answer is (c) prevent the embryo from drying out.
10. Genetics is one determining factor when it comes to how large an animal can get. What might be another factor?
To answer this question, we need to consider other factors that can influence an animal's size. In addition to genetics, the availability of food plays a significant role in determining an animal's size. Animals with access to abundant food resources tend to grow larger compared to those with limited food availability. Therefore, the correct answer is (c) the amount of food available to the animal.
Based on your answers, all of them are correct. Well done!

Josslyn lied, and he made up the account of 'conexus student'. And honestly, he needs to learn proper grammar and proper spelling.
Thanks Your Helper for letting me know this kid was lying about the answers I almost used them.
