Why might a rancher plant several varieties of grass fro grazing on the same ranch
BigorU [14]

The reasons why a rancher may plant several varieties of grass for grazing on the same ranch are for making hay where some horse owners may prefer to feed their animals with a feeding mixture of alfafa hay and timothy hay.  Secondly, they plant the grasses for grazing their animals since the grasses may be having different soil conditions in different fields. lastly, the farmers may be raising different animals with varying nutritional needs.

1.) Which of the following is an electron carrier used to transfer energy in cellular respiration?
Anestetic [448]

Answer:

1. B. NADH

2. B. hydrolysis of ATP.

3. C. ATP is produced from protein.

4. Option C.

5. Option C. Oxygen

6. Option D. Glucose.

7. Carbondioxide.

8. Metabolism.

9. Electron carriers.

10. Electrons.

Explanation:

Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.

Can you define these words?? Thanks!
padilas [110]

Answer:

<u>Cellulose</u> - 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.

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

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

<u>Bryophyte</u> - 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.

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

<u>Gymnosperm</u> - 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.

<u>Cone</u> - A cone-shaped flower head of various plants like banksias and proteas.

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

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

<u>Cuticle</u> - A noncellular protective covering outside the many invertebrates and plants.

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

<u>Xylem</u> - 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.

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

<u>Roots</u> - 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.

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

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

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

<u>Photosynthesis</u> - 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).

How the process of natural selection canexplainhow evolution occurs?
harkovskaia [24]
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
