Carbon dioxide A) made when it reacts to oxygen
Nitrogen oxides B) released when burning coal or gas
Volatile organic compounds C) emissions from oil refineries
Sulfur oxides D) cleaning, disinfecting, and degreasing products
The pollutants and their respective sources include the following
Carbon dioxide - This is released when burning coal or gas. The burning of
fossil fuels such as coal or gas releases the greenhouse called
carbondioxide and is responsible for increase in infrared absorption to the
earth.
Nitrogen oxide: This is made when nitrogen reacts with oxygen under the
appropriate conditions.
Sulfur oxides : This is contained in emissions from oil refineries. This is
because crude oil which is the major raw material in refineries have large
amounts of sulphur in them which reacts with oxygen to form sulfur oxides.
Volatile organic compounds: These are contained in cleaning, disinfecting,
and degreasing products.

How do animals cause erosion.
Answer:
Some animals weather rocks by scraping them as they feed. Other animals change Earth's surface by burrowing into it and moving material. Too many animals in one place can destroy most of the plants, leading to faster erosion.
If too many animals graze the same land area, the animals’ hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.

Mendel knew that the variations in the offspring generations resulted from his experiments because he
Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.
Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.
Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

Why do the alveoli fill with fluid.
Answer:
Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.
Explanation:
Answer:
The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

IQ is determined by ; ( D ) multiple genes and environmental factors
IQ ( intelligence quotient ) is influenced by more than a single gene ( i.e. multiple genes ) and this makes IQ a polygenic trait found in organisms such as humans.
IQ is not only determined by multiple traits but is strongly influenced by environmental factors just like the multiple genes. IQ measures the intellectual ability of humans ( i.e ability to read and think critically outside the box and also think logically . )
Hence we can conclude that IQ is determined by multiple genes and environmental factors

A female mouse is trying to decide if she will leave her natal nest to reproduce alone. If she leaves, she will be able to produce 45 offspring whereas she would only have 7 reproductive units if she stayed. But if she stays, she will help her mother produce 175 offspring vs the 85 she could produce without her. Should she stay
Answer:
142 is the answer whe you add 45 7 and 85
A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.
What is reproduction?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.
In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.
Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.
Therefore, A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

What is the role of chromosomes in the cell nucleus?
Explain in 5 - 10 sentences
Answer:
Chromosomes are tightly packed DNA and proteins. The DNA and proteins take on a tightly coiled structure within the chromosome. The chromosomes are then kept inside the nucleus. Their role is to carry basic genetic material. This provides the cell with genetic information that's used to carry out different cellular functions. These functions include survival, growth, and the ability to reproduce.
