If the birth rate of a population of dolphins is 2.0, the death rate is 0.5, and the population size is 100, what is this dolphin's population growth?
Answers
Answer: The dolphin's population growth is 150% .
Explanation:
The birth rate of dolphins =
The death rate of the dolphins =
Dolphin's population growth = Birth rate - Death rate
=
The dolphin's population growth is 150%.

The flowering plants tend to reproduce more in the warmer summer months.
How does warm temperatures affect plants?
- Warm temperatures are unfavorable to plants.
- Photosynthesis occurs at a slower rate.
- The rate of transpiration rises.
What is the effect on the reproduction?
- The plants start flowering and is rate of flowering increases.
- However these plants show reduced seed setting or fruit development.
Why does it occur?
- It happens because these temperatures are unfavorable to the plant.
- To escape this unfavorable condition they complete their life cycle as soon as possible.

Answer:
The total of O2 + CO2 is not a mathematical expression that can be added together.
O2 and CO2 represent different chemical compounds: O2 refers to oxygen gas (two oxygen atoms bonded together), and CO2 refers to carbon dioxide (one carbon atom bonded to two oxygen atoms).
In chemistry, we do not add or combine the formulas of different compounds in the same way we add numbers. Instead, we use chemical reactions and equations to understand how elements and compounds interact and form new substances.
b. algae
c. trees
d. photosynthetic bacteria

Chemosyntheticbacteria do not require sunlight for their survival. So the correct option is A.
What is chemosynthesis?
Autotrophicorganisms like plants prepare their food by using sunlight as a source of energy which is converted to chemical energy. But some bacteria, that live deep below the surface of the ocean use chemicalenergy to prepare this food.
This process is known as chemosynthesis as it uses chemical energy instead of light energy. It uses carbon in the form of carbon dioxide or methane and some inorganic nutrients which are converted into organic matter.
In this process, the inorganicmatter is oxidized to produce energy. In a specific mind of chemosynthesis called hydrogen sulfide chemosynthesis, carbon dioxide and oxygen are used to produce CH₂O, a carbohydrate.
Following is the reaction
CO₂ + O₂ + 4H₋S → CH₂O + 4S + 3H₂O
The organisms that perform chemosynthesis are called chemoautotrophs.
Therefore the correct option is A.
