Ques: Q: What is the science that describes the ancestral and descendant connections between organisms? Read this paragraph and choose the correct option from the provided answers: Building Phylogenetic Trees with Analysis of DNA Sequence Alignments All living organisms display patterns of relationships derived from their evolutionary history. Phylogeny is the science that describes the relative connections between organisms, in terms of ancestral and descendant species. Phylogenetic trees, such as the plant evolutionary history shown in Figure 26.7, are tree-like branching diagrams that depict these relationships. Species are found at the tips of the branches. Each branching point, called a node, is the point at which a single taxonomic group (taxon), such as a species, separates into two or more species. Choices: - experimentally - organic science - polygamy - phylogeny A:
Ans: phylogeny

Ques:Q: What is a copy of an image formed by reflection or refraction? Read this paragraph and choose the correct option from the provided answers: A mirror is typically made of glass with a shiny metal backing that reflects all the light that strikes it. When a mirror reflects light, it forms an image. An image is a copy of an object that is formed by reflection or refraction. Mirrors may have flat or curved surfaces. The shape of a mirror's surface determines the type of image it forms. For example, some mirrors form real images, and other mirrors form virtual images. What's the difference between real and virtual images?. Choices: - an example - a photographic image - a mirror image - an image A:

Ans:an image

Ques: Q: What are the organs work together to allow us to see? Read this paragraph and choose the correct option from the provided answers: The ability to see is called vision. The brain and eyes work together to allow us to see. The eyes collect and focus visible light and change it to electrical signals that travel to the brain. The brain interprets the signals and "tells" us what we are seeing. Choices: - lungs - heart - nose - brain and eyes A:
