Answer:
B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.
Explanation:
Conjugation is a process by which bacteria can exchange their genetic material between them. So through conjugation, the antibiotic-resistant gene coded by plasmid can be transferred through sex pilus to another bacteria.
So due to conjugation two different species of bacteria can share DNA which can include antibiotic-resistant genes. Therefore, through conjugation genetic variation and evolution are favored in bacteria. So due to this reason conjugation is a very important process in bacteria to spread antibiotic-resistant genes.
Answer:
- They are made of denser objects, which can condense at relatively high temperatures;
- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide
The economy moved to growth due to the infrastructure activities, the main driver of economy is tourism.
They produce oxygen they are used as shelter, they are used for blocking the shade, they sustain other animals that sustain the planet and us.
