Which of the following is a biotic factor in a biome?
a
kinds of birds
b
amount of rainfall
c
types of rocks

Answers

Answer:

The answer to this is A

Explanation:

A biotic factor is an organism that is living, and rainfall and rocks would be abiotic factors, therefore A is the correct answer.

Hope this helps :D

A living thing that alters its surroundings is referred to as a biotic factor. Examples of kinds of birds, and habitats include algae, fish, amphibians, and aquatic plants, hence option A is correct.

What is a biotic factor?

The ecosystem's biotic components are alive or extinct creatures. These can reproduce and they are taken from the ecosystem. Animals, birds, plants, fungi, and other similar species are examples of biotic factors.

Biomes, scientists may identify a biome by defining the temperature range, soil type, and amounts of light and water that are peculiar to that location and create niches for various species.

Therefore, the kind of birds is a biotic factor in a biome, and the amount of rainfall and types of rocks are not biotic factors, hence option A is correct.

When lung cells get damaged, this can lead to a disease, such as chronic lower respiratory disease. In your own words, explain how damaged cells can lead to a disease. EXPLAIN!!


(This is 7th grade science.)

Answers

Answer:

Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease:

Airway diseases -- These diseases affect the tubes (airways) that carry oxygen and other gases into and out of the lungs. They usually cause a narrowing or blockage of the airways. Airway diseases include asthma, COPD and bronchiectasis. People with airway diseases often say they feel as if they're "trying to breathe out through a straw."

Lung tissue diseases -- These diseases affect the structure of the lung tissue. Scarring or inflammation of the tissue makes the lungs unable to expand fully (restrictive lung disease). This makes it hard for the lungs to take in oxygen and release carbon dioxide. People with this type of lung disorder often say they feel as if they are "wearing a too-tight sweater or vest." As a result, they can't breathe deeply. Pulmonary fibrosis and sarcoidosis are examples of lung tissue disease.

Lung circulation diseases -- These diseases affect the blood vessels in the lungs. They are caused by clotting, scarring, or inflammation of the blood vessels. They affect the ability of the lungs to take up oxygen and release carbon dioxide. These diseases may also affect heart function. An example of a lung circulation disease is pulmonary hypertension. People with these conditions often feel very short of breath when they exert themselves.

Petroleum now let's see...Petroleum also used for cars and other vehicles is distributed around the world for different uses. Today, fossils fuels are necessary for human survival and everyday life and are the primary source for the world’s energy. They are used for heating, transportation, generating electricity, and creating common products like computers, cosmetics, paint, and household appliances.

“Years ago, when prehistoric animals and plants died, layers of rock and dirt gradually buried them. Over millions of years, heat and pressure from Earth's crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal.”

n a particular board game, there is exactly one row and it comprises N spaces, numbered 0 through N - 1 from left to right. There are also N marbles, numbered 0 through N - 1, initially placed in some arbitrary order. After that, there are two moves available that only can be done one at a time: Switch: Switch the marbles in positions 0 and 1. Rotate: Move the marble in position 0 to position N - 1, and move all other marbles one space to the left (one index lower). The objective is to arrange the marbles in order, with each marble i in position i. 1. Write a class, MarblesBoard, to represent the game above. The class should be initialized with a particular sequence of Marbles. Write an __init__ function that takes a starting sequence of marbles (the number of each marble listed in the positions from 0 to N - 1). (Notice in the sequence all the marbles are different numbers and are sequential numbered but not in order!) Next, write switch() and rotate() methods to simulate the player's moves as described above. Write a method, is_solved(), that returns True if the marbles are in the correct order, False otherwise. Additionally, write __str__ and __repr__ methods to display the current state of the board.
