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).

The minimum amount of muscles needed to move a joint is ______.
A. 4
B. 3
C. 2
D. 1
Answer:
C. 2 one muscle contracts while the other muscle relaxes and becomes longer
Explanation:
hope this helps :))
The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
What are Muscles?Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.
Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.
A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.
Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.

Answer:
Decomposer
Explanation: I just did it
An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.
What is the decomposer's importance?Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.
Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

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.

energy being transferred from wind
energy from the Sun heating water
Answer: Energy being transferred from wind
Explanation: I just answered this question
Waves in the ocean are occurs due to the transfer of energy from the wind. Therefore, option C is correct.
What causes waves in the ocean?Numerous events, including earthquakes, volcanic eruptions, and landslides, can result in waves, although surface waves brought on by winds are the most frequent ones (CoastalCare). A wave forms when the wind blows across the water's surface, generating friction between the air and the water.
There are numerous types of waves, including tidal waves, wind waves, ocean swells, and tsunamis. Three factors: the wind's speed, the length of time it takes to cross the ocean, and the distance it travels, all affect how large the waves become.
The most common cause of the formation of waves in the ocean is the transfer of energy from the wind. Therefore, option C is correct.
