Does acid precipitation in forests affect the reproduction rate in birds?

Answers

By reducing food sources, harming habitats, and resulting in calcium-related problems with eggs, acid precipitation in forests has the potential to reduce the rate of bird reproduction.

Yes, acid precipitation in forests has the potential to reduce bird reproduction rates by destroying their habitats, decreasing food sources, and directly damaging eggs and chicks through calcium depletion and disturbance of aquatic feeding systems.

Acid rain can cause soil and water to become more acidic, which reduces the amount of insects and aquatic life that birds rely on for food. Additionally, the thinner eggshells brought on by calcium leaching from the soil as a result of increased acidity can reduce the success of hatching.

There is evidence to show that acid precipitation can have detrimental effects on bird reproduction in impacted locations, albeit the magnitude of the impact varies depending on the specific bird species, ecological circumstances, and the severity of the acid rain.

B) The product contains more juice than water.
C) The product contains more sugar than juice.
D) The product contains more sugar than any other ingredient.

Answers

Answer:

Explanation:

C is the only one that is true. Because sugar comes before juice in the ingredients listed, there is more of it.

true or false: ionic bonding involves the shareing of electrons, oxide ions have a 2+ charge , electrons have a negative charge , a hydrogen molecule is held together by a strong covalent bond between two hydrogen atoms, a covalent bond is a shared pair of electrons.

Answers

Ionic bonding does not involve the sharing of electrons, that one is false. In ionic bonding, the metal's electrons are given to the non-metal, so that they're both like the nearest noble gas (full electron shells.) They are then drawn together because one has a negative charge (the non-metal) and one has a positive charge (the metal.)

Oxide ions have a 2+ charge: This is false, oxide ions have a 2- charge.

Electrons do have a negative charge, this is true.

Hydrogen molecule: pretty sure this is true. We know this because both atoms are non-metals.

The last one is true: a covalent bond is a shared pair of electrons between two atoms, however be aware that there can be more than one covalent bond between two molecules.

Answer:

False , shared electrons cause covalent bonds
False , they have 2- charge
True
True
