Answer:
The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.
Answer:
1500Joules
Explanation:
Work done, denoted by W, can be calculated using the formula:
Work done (W) = force (F) × distance covered (d)
According to the information in this question, Mary pushes her cart across the floor with a force (F) of 150N for a distance (d) of 10m.
Hence, work done (W) by the cart is:
W = 150N × 10m
W = 1500 Newton.metre (N.m) or Joules (J).
<h2>Answer is option "A"</h2>
Explanation:
- A small proportion of water atoms contain the heavier isotopes of hydrogen and oxygen. There is a tendency for these heavier particles of water to gather in leaves during transpiration.
- This has a few fascinating repercussions, remembering impacts for the isotopic piece of natural issue, and of air-water fume, carbon dioxide, and oxygen.
- These impacts help transient recreation of atmosphere and spatial and worldly reproduction of essential creation in different manners.
- Hence, the right answer is option A "When heavy oxygen is part of water given to the plant, the plant produces heavy O2."
Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.
