In gymnosperms, pollination can occur by _____.
gladu [14]
The wind makes pollination possible for gymnosperms. In gymnosperms ovaries are absent and the gametophytes of these plants are present on cones rather than flowers. Unlike angiosperms that get pollinated with animal interference, wind plays a crucial role in gymnosperm pollination.

USPshnik [31]

Answer:

See the answer below

Explanation:

First, let us look at the complete equation of respiration:

C_6H_1_2O_6 + 6O_2 -->6CO_2 + 6H_2O

The respective number of each atom in the reactants and the products can be filled in the table thus:

Types of atom   Number of atom in reactants   Number of atom in products

Carbon                                6                                                    6

Hydrogen                            12                                                   12

Oxygen                               18                                                    18

<em>The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction. </em>

the risks of indoor cooking with biofuels and poor ventilation can be reduced through: group of answer choices cooking with more
Vikki [24]

The risks of indoor cooking with biofuels and poor ventilation can be reduced through: better ventilation.

<h3>What is chemical pollution?</h3>

Chemical pollution can be defined as the contamination of an environment or waterway, especially through an emission of poisonous, hazardous, and toxic chemical compounds (substances) by humans and various industries.

According to the Environmental Protection Agency (EPA), chemical pollution is a change to waterways and the atmosphere which are mainly caused as a result of human activity.

In this scenario, we can reasonably infer and logically deduce that the risks of indoor cooking with biofuels and poor ventilation can be reduced through better ventilation in the cooking area, so as to efficiently and effectively diffuse the gases.
