Answer: 1. true
2. false
Explanation:
1. Chrysophytes can be defined as the algae that can be found in the lakes. They have photosynthetic pigments carotenoids which impart golden yellow color to these algae. They are unicellular and also have flagellum that help them in movement in water.
2. Diatoms are unicellular algae. They appear as single individual cells or may appear in colonies with other cells. They can take up any shape based on their alignment pattern. Each cell is surrounded by cell wall that is composed of silica called as frustule. They can be found in fresh or marine water.
Answer;
an orange that has a prolonged shelf life
Explanation;
-Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism.
-Examples of genetically engineered (transgenic) organisms currently on the market include plants with resistance to some insects, plants that can tolerate herbicides, and crops with modified oil content.
-Genetic engineering works by physically removing a gene from one organism and inserting it into another, giving it the ability to express the trait encoded by that gene. It is like taking a single recipe out of a cookbook and placing it into another cookbook.
They both use a reproductive strategy called alternation of generations, where there are two different reproducing morphologies: a diploid sporophyte, and a haplod gametophyte. The sporophyte produces spores by meiosis (2N -> N), which disperse and form the gametophyte, which produces gametes by mitosis (N ->N). Two of those gametes fuse to create a diplod zygote (N + N -> 2N), which becomes the new sporophyte
There are differences between the two types of plants, especially the relative size of the sporophytes and gametophytes, but they both use this kind of reproductive strategy.
