Answer:
Offspring of two different true-breeding varieties are called hybrids.
Explanation:
Pure-breeding plants are plants that self pollinate for many generations and all its offspring had the same features as the parents, generation after generation.
When Mendel cross pollinate this pure-breeding plants with contrasting traits, the offspring is called hybrids because they resulted from a cross between two pure-breeding plants with contrasting traits.
Answer:
I'm guessing there is no answer choices but, "It holds its shape because the molecules of the water are attracted to each other."
Answer:
Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature. Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: 3
Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure. Monounsaturated fats are typically liquid at room temperature and include canola oil and olive oil.
Polyunsaturated fats: This type of unsaturated fat contains two or more double bonds in their structure. They are liquid at room temperature. Polyunsaturated fats include safflower oil, sunflower oil, and corn oil.
Explanation:
Answer:
1. FtsZ tubulin homolog
2. actin and tubulin
3. actin and tubulin
4. b. animals and bacteria
Explanation:
1. In bacteria, the binary fission process takes place when the cytoskeletal structure of the bacteria are assembled to form the contractile ring in the centre of the cell. The contractile ring in bacteria is composed of the Z-protein which is a tubulin homolog.
2. Plants: the plants divide by the cell plate formation and not the contractile ring formation. This is mediated by the actin, tubulin and vesicle produced from the dictyosomes.
3. Animals: a contractile ring attached to the plasma membrane is formed which is composed of the F-actin and tubulin.
4. Since the bacteria and animal cytokinesis involves the formation of the contractile ring and thus the same mechanism of cytokinesis.
