In which motions are the distance and the displacement the same?
A. A dog chases its tail in a circle four times
B. A bird flies from its nest to the ground and back to its nest.
C. A worm moves 5 cm along a straight crack in a sidewalk.
D. A fish swims all the way across a pond and then halfway back.
Answer: A. A dog chases its tail in a circle four times.
Explanation:
Distance can be defined as a scalar quantity. It describes how much area the object covers during its motion. Displacement can be defined as the vector quantity. It refers to the fact that how far an object is from a place. It describes the overall change in the position of the object.
A dog makes a circle four times chasing the tail thus its direction will remain the same. Its position will remain the same after motion, thus no displacement will occur. The dog is making a circle on the same place while chasing the tail hence the distance covered will become equal to the net displacement.

a report on the role of chromosomal multiplicity(polyploidy)in the field of agriculture.
Not less than 50 words.
50 points plz help me guys !!
Answer and explanation:
Chromosomal multiplicity, also known as polyploidy, is the name given to the cell or organism that has a numerical change in its whole set of chromosomes (for example, a triploid organism of a diploid species is a polyploid because it has an extra set of chromosomes than the rest of its species). Most species are diploids, but polyploidy is quite common in plants.
In agriculture, polyploidy can be beneficial by giving the plants better chances of survival and/or providing more desirable traits. Crop species such as bread wheat and triticale (a wheat and rye hybrid), for example, have 6 sets of chromosomes. Quinoa, coconut, and peanut are tetraploids (4 sets of chromosomes). Many of these cases of polyploidy in plants of importance for the agriculture field are a result of hybridization (which occurs when two different species are crossed in order to produce offspring with a combination of characteristics of the two-parent species).
what is the role of a cytoplasm
Answer:
Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place
Explanation:
Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.

Explanation:
True or false? To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is required.
Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.
Explanation:
To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is not required. Thus, the given statement is false.
What is energy cycle in an ecosystem?The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.
The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

Explain how your model demonstrated energy transformation from thermal energy to mechanical energy during a volcanic eruption.
(I mixed warm water, vinegar, and baking soda)
Answer:
Well to begin with, the thermal energy is mostly provided by the energy contained in warm water, when mixed with the other two components the chemical units are modified to form a composite solution that will result in an energy release, this energy release generate a movement, which in this case is the eruptive movement simulating the eruption of a volcano.
Explanation:
By mixing the vinegar (which is an acid) with the baking soda (which is a base), they react and transform into water, sodium acetate (a salt), and carbon dioxide (a gas). Carbon dioxide (CO2) is the gas that causes bubbles to form from the eruption of the volcano and balloons to swell.
how might smartphones linked to climate change
Answer:
Smartphones and data centres are damaging to the environment and will have the biggest carbon footprint in the tech industry by 2040, researchers have found. ... While these phones consume little energy to operate, 85% of their emissions impact comes from production, the researchers said.
Explanation:
Answer:
Making a phone accounts for 85–95 percent of its annual carbon footprint because manufacturing its electronics and mining the metals that go into them is energy-intensive. The analysis showed that smartphone emissions will go up from 17 to 125 megatons of carbon dioxide equivalent between 2010 and 2020.
