Huntington’s disease: Huntington’s disease is a disease in which certain parts of the brain waste away; symptoms usually begin l
neonofarm [45]

Answer:

Regarding Huntington's disease, it can be said that it is an inherited disease with an autosomal dominant character, so it is enough that one of the children inherits one of these characters to manifest this neurodegenerative disease, it is considered that the pattern is usually 50% of the total of children of sick parents can suffer it, however if both parents are carriers the number rises leading to 100% of the children affected, on the contrary if no parent has the dominant gene and are homozygous recessive, neither your children will suffer the disease

The possibilities are the following:

Parent 1, inheritance pattern: Hh * hh, the possible gametes for this cross-linking are H, H, h, h, offspring; Hh, Hh, hh, hh 50% of the children could be sick

Parents 2, inheritance pattern: hh * hh, the possible gametes for this cross-linking are h, h, h, h. the offspring will be; hh, hh. no sick child

Parent 3, inheritance pattern: HH * HH, the possible gametes for this cross-linking are H, H, H, H, the offspring will be HH, HH, all children may be sick, 100%

parents 4, inheritance pattern: Hh * Hh, the possible gametes for this cross-linking are h, H, h, H. the descendants will be HH, Hh, Hh, hh 50% of sick children

Parents 5, inheritance pattern: Hh * hh, the possible gametes for this interbreeding are H, h ,, offspring will be Hh all sick children

Parent 6, inheritance pattern: Hh * Hh the possible gametes for this cross-linking are H, h, the descendants will be Hh, the heterozygous descendants will have the disease.

A student drew the diagram below to model the process of binary fission, which is a type of asexual reproduction.
Leno4ka [110]
The answer would be: <span>Binary fission involves a single parent cell, so there is only one set of genetic information that can be duplicated and passed on to the daughter cells.

If you see the picture, it is clear that there is only 1 parent involved in binary fission. This will exclude the first and third option. 
The genetic duplicated before splitting, so the cells should have an equal number of parent genetic material, not halves. This will exclude the second option.

Which scenario describes a way that an abiotic factor can impact a marine system? Liquid water turning into solid ice encourages
Sloan [31]

Answer:

Rapid increases in water temperature cause extensive fish kills

Explanation:

Biotic factors are all living organisms that contribute to an ecosystem. On the other hand, abiotic factors are non-living factors, such as climatic factors (temperature, rainfall, wind), edaphic factors (soil type, soil texture, soil aeration etc). Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.

Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.

Which enzymes are found in detergents that remove mucus and oil stains from cloth soaked in water ?​
Annette [7]

Answer:

Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
