Answer:

Option D

Explanation:

(the gene for the disease has incomplete penetrance. the gene for the disease has limited expressivity. the disease is polygenic) - all these are examples of non-mendelian inheritance which include incomplete penetrance, polygenic inheritance etc. These do not follow the mendelian pattern of inheritance.

(the gene for the disease is recessive.)- this shows the mendelian pattern of inheritance... Dominant and recessive characteristics are examples that show Mendelian inheritance.

What is the third type of variation in Mendel's theory?
Nikitich [7]
The three most important Mendel law is the law of dominance, law of segregation, and law of independent assortment. The law of dominance is when a trait is more recived or more dominate than other trait. For example a flower, if a flower is red most of the flowers will be red, but one will be white. The white flower has a recessive trait. The law of segregation is when a offspring randomly receive one allele of every trait from each parent. The law of independent assortment states that just because you received one allele doesn't mean another dominate allele will be passed also.

What is the symbol for lipids, DNA and proteins
son4ous [18]
<span>Symbols for lipids is C and H.
It also contains Nitrogen and phosphorous. DNA or RNA their symbol is C, H, O, N, P. Protein contains both sulfur and selenium which are C, H, O, N, P. Proteins are subunits of amino-acids.
Proteins can be carriers, signaling structural and also immune responses. They are made of the nucleus.
 Lipids are hydrophobic and are naturally found in the body to mean that they don't mix with water reason being they are non-polar. Lipids make up phospholipids bilayer.
DNA is supercoiled, and their backbone which is made up of phosphate and sugars groups.</span>

Without bacteria in the environment
timurjin [86]

Answer:

e. All of the choices are correct.

Explanation:

Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.

Many nitrogen-fixing bacteria like Rhizobium,  Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.  

So bacteria like <em>Pseudomonas putida</em> decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.
