If a population grows larger than the carrying capacity of the environment, the most likely to happen is:
A. The death rate may rise.
When a population grows larger than the carrying capacity of the environment, the resources available to the population will be depleted. This can lead to a decrease in the availability of food, water, and shelter. As a result, the death rate may rise.
The birthratemay also rise, but this is less likely. If the resources are already depleted, there may not be enough food and water to support a larger population. In addition, the stress of living in a crowded and resource-depleted environment may lead to an increase in stress-related deaths.
The other options, B. The birthrate may rise, C. The death rate must fall, and D. The birthrate must fall, are incorrect. The birthrate may rise, but it is not guaranteed. The death rate may fall, but it is not necessary. The most likely outcome is that the death rate will rise.
This is a concept known as carrying capacity, which is the maximum population size that an environment can sustain indefinitely. When a population exceeds the carrying capacity, the population will eventually crash. This can happen through a number of mechanisms, including starvation, disease, and conflict.

B. the epidermis consists of mostly adipose cells.
C. the epidermis is thicker.
D. the dermis is made of mostly dead cells
The list which includes elements with the most similar chemical properties is; Choice 3: O, S, Se
First, we must know:
Elements are arranged in 7 Periods and 18 groups in the periodic table.
Additionally, Elements in the same group of the periodic table often have similar chemical characteristics as a result of equal number of Valence electrons.
By considering Choices individually;
For Choice 1: (Br, Ga and Hg)
For Choice 2: (Cr, Pb and Xe)
For Choice 3: (O, S and Se)
For choice 4: (N, O and F)
Ultimately, the correct answer is Choice 3.

Answer: The correct answer is Option 3.
Explanation:
Elements are distributed in 7 Periods and 18 groups in a periodic table.
Elements which belong to same group show similar chemical properties because of the same number of valence electrons.
For the given options:
Option 1: Br, Ga and Hg
Bromine is present in Group 17, Gallium is present in 13 and Mercury is present in Group 12.
As, all the three elements belong to different groups. So, they do not show similar chemical properties.
Chromium is present in Group 6, Lead is present in Group 14 and Xenon is present in Group 18.
As, all the three elements belong to different groups. So, they do not show similar chemical properties.
Oxygen, Sulfur and Selenium are present in Group 16.
As, all the three elements belong to same group. So, they will show similar chemical properties.
Nitrogen is present in Group 15, Oxygen is present in Group 16 and Fluorine is preset in Group 17.
As, all the three elements belong to different groups. So, they do not show similar chemical properties.
Hence, the correct answer is Option 3.
(2) The gas particles are in constant, nonlinear motion.
(3) The gas particles have attractive forces between them.
(4) The gas particles have collisions without transferring energy.
Answer : The limiting reagent is .
Solution : Given,
Mass of = 4.0 g
Mass of = 8.0 g
Molar mass of = 17 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 mole of react with 4 mole of
So, 0.25 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Hence, the limiting reagent is .
