Which gas directly increases the global temperature the most?
Answer:
Greenhouse Gases
Explanation:
A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth.
Answer:
CO2 increases global warming temp the most followed by CFCs ( chlorofluorocarbons) which are used in refrigerators and ACs but now banned.

Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16
HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

The movement of waves in the middle of the ocean is normally
static
vertical
circular
horizontal
Answer:
Vertical
Explanation:
Since we are talking about movement, and the ocean can't be static due to many things happening around and inside it can't be static.
It is not circular and not horizontal. It is vertical. The movement of waves is vertical and this is because waves don't move up and down but vertically since wind is the usual maker of waves in the middle of the ocean.
