"A" does not describe bacteria. Bacteria use cellular respiration to produce energy, and therefore do not produce oxygen. However, millions of years ago, cyanobacteria did produce oxygen.

He three types of seismic waves produced by an earthquake are primary, secondary, and

Westkost [7]

Seismic waves are waves produced by earthquakes. This occurs when rocks under the earth suddenly break or explode. There are two MAIN TYPES of seismic waves called body waves and surface waves. Body waves have the capacity to travel through the Earth's inner layers. They have a higher frequency and they are the ones that first occur under water at the onset of an earthquake. They can be subdivided into two types, the primary and secondary waves that arrive at seismic records one after another.

Surface waves can only traverse through the surface of the planet like ripples in the water. These waves can easily be detected on a seismogram result. These waves arrive after body waves and they are the ones mostly responsible for damages and destruction bought by earthquakes.

Describe the mutation in a plant that could have a negative outcome for the organism

iris [78.8K]

A mutation in a plant that could cause negative outcomes could be the plant has less leaves, or isn't hardy enough, like other plants. It would die. A plant from an area like Chernobyl, that has been affected by radiation could poison other animals, or pass that gene along, and ultimately kill that strand of plant.

Can you define these words?? Thanks!

padilas [110]

Answer:

Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.

Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.

Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.

Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.

Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.

Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.

Cone - A cone-shaped flower head of various plants like banksias and proteas.

Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.

Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.

Cuticle - A noncellular protective covering outside the many invertebrates and plants.

Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.

Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.

Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.

Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.

Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.

Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.

Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.

Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).
