Answer:
Plant and animal cells have a plasma membrane, a nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, peroxides, and micro-tubules.
Explanation:
Both animal and plant groups have few alike structural elements. Leading off, they are both eukaryotic, which indicates they have a specified nucleus. The nucleus comprises chromosomes. It is guarded and enclosed by the cytoplasm, which is a wet or gel-like liquid. Animal and plant cells own a cell membrane that encloses the cell.
Their biggest threats
The absence of an appropriate habitat for bees could lead to a continuous decline in pollination. Mono-cropping, pesticides, and higher temperatures associated with climate change all pose problems for bee populations and, by extension, the quality of food we grow.
Answer:
Answer is C.
When a household installs a dual flush toilet, the water is mainly conserved by limiting its consumption and thus eliminates the unnecessary loss of water.
Explanation:
A dual flush toilet is similar to a standard toilet but includes some water conserving features. It is an effective way to reduce the amount of water used in flushing
. It has two buttons to select two different flush settings, one for the liquid waste and the other for solid waste. Normally less water is needed to get rid of liquid waste than solids. Some models of dual flush toilet system reuses the water in the hand washer for flushing. Standard toilets use siphoning action, where a siphoning tube is used to drain the waste. While flushing, a large volume of water enters the toilet bowl which fills the siphon tube and siphon pulls the waste and water down the sewer pipe. The siphoning action stops, when the bowl emptied and air enters the tube producing a gurgling sound. Dual flush toilet has a large hole at the bottom of the bowl and a wash down flushing design to push the waste down into the drain. This system needs less water per flush as no siphoning action is required. Also the waste is easily drained out of the bowl because of the large hole at the bottom of the bowl. In a dual flush toilet, the liquid waste flush utilizes only half the amount of water than the solid waste flush. The main disadvantage of a dual flush toilet is that it is more expensive than a normal toilet..
Answer:
The author means to say that Genetic difference exist between different species.
Explanation:
Comparison between protein and nucleic acid
Similarity
1 Both nucleic acid and Proteins are Macromolecules
2 Both nucleic acid and protein are the main component of central dogma of molecular biology
Difference
1 nucleic acids are the polymer of nucleotides whereas proteins are the polymer of amino acids.
2 nucleic contain nitrogen bases whereas protein contain open reading frame composed of codons.
