I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Hi! :)
The amount of uranium within nuclear fuel rods is enough to sustain a chain reaction but is less than the critical mass necessary for the reaction to become explosive.
Description of thigmotropism is given below.
Explanation:
1. Thigmotropism is a plant’s response to touch.It is a plant’s response to an external stimulus.It can occur quickly or slowly.Thigmotropism may involve the closing and opening of plant leaves.
2. Thigmonasty or thigmotropism can be define as the response of touch shown by the plants. Here, touch is the external stimulus. It can be define as the movement of the plant parts in response to the external stimulus that is contact or touch. It is also known as Haptotropism. The plant may change it's orientation, shape and size of the plant parts.
3,The thigmotropism can be positive or negative depending upon the visual response shown by the plants. The response shown by the plants is generally fast but may be slow. This response is shown by the plants in cases of danger of herbivory.Some plants like Mimosa pudica or touch me not plant shows thigmotropism by closing their leaves on touch
1. The correct answer is A. silicone.
Silicone is also referred to as polysiloxanes. They are termed as polymers which include any inert. It is a synthetic compound which is made up of repeating units of siloxane. They are heat resistant and rubber-like. They are used in medicine, lubricants, cooking utensils, and electrical insulation.
2. The correct answer is C. Formulating the mix.
It is a way of marketing. There is no formula for multi-channel marketing. The most effective nowadays is multichannel and integrated.
3. The correct answer is B. humus.
Humus is termed as the dark organic matter which forms in the soil when dead plants and animals matter decays. It has a lot of nutrients which helps to improve the health of the soil and most important is the nitrogen. It affects the bulk density of soil which contributes to its retention of nutrients and moisture.
4. The correct answer B. Sweet.
The red soil is described by sweet. Sweet is something which smells good. Red soil develops to temperate, warm, moist climate which is under mixed forest. It has a thin organic and inorganic mineral layer. They are derived from crystalline rock.
5. The correct answer is B. Casting with sulfur.
Sulfur casts have both sides which have the same cast as the original.
