`A` có `8` tập con đó là:

{\(\emptyset\)} ; {`0`} ; {`1`} ; {`2`} ; {`0;1`} ; {`0;2`} ; {`1;2`} ; {`0;1;2`}

Tập con có không phân tử là : \(\varnothing\)

Có 1 phần tử : \(\left\{0\right\};\left\{1\right\}:\left\{2\right\}\)

có 2 phần tử :  \(\left\{1;0\right\};\left\{2;0\right\};\left\{1;2\right\}\)

có 3 phần tử : \(\left\{1;0;2\right\}\)

=> tập A có 8 tập con 

6 tập con: {0;3}; {0;4};{0;6};{3;4};{3;6};{4;6}

\(A=\left\{3;0\right\};\left\{4;0\right\};\left\{6;0\right\};\left\{3;4\right\};\left\{3;6\right\};\left\{4;6\right\}\)

=> D 

Vì mặt trời là nguồn cung cấp nhiệt cho trái đất. Nếu ko có nhiệt độ thì các loài sinh vật sẽ ko giữ đc sự sống điển hình như nước bị đóng băng, ....

Ngoài ra đa số thực vật duy trì sự sống nhờ sự quang hợp từ ánh sáng mặt trời. Nếu cây ko quang hợp thì cây ko sinh ra dưỡng khí, khi đó lượng dưỡng khí sẽ nhanh chóng cạn kiệt và trái đất trở thành hành tinh chết

-> Bị hủy diệt

đây là kiến thức mik tự luận đc, nếu bn có hiểu biết rộng hơn về vũ trụ, các hành tinh thik bn có thể liệt kê ra nguyên nhân nhiều hơn nha
