Answer: D) harmless plant proteins  

Pollen is a male gamete, which is produced by the flowers in order to conduct fertilization of female gamete or ovule. The pollen contains proteins which acts as an antigen. When these proteins or antigens are inhaled by the living organisms like humans it creates an allergic response in them. This occurs due to the fact that, when body receives a foreign antigen, the body immune system gets activated and it produces antibodies against it, to expel it out of the body by sneezing.  

According to the above information, the culprit is affected by harmless plant proteins, which will originate an allergic response, causing Juan to sneeze when he sniffs the morning glory flower.

Answer:

the flavor will neutralize

Explanation:

if you're plugging your nose, it blocks most of the taste out of a food item. so while biting into an onion while plugging your nose, it will neutralize the strong flavor and make it taste more like an apple or potato since they have very similar textures. hope this helps!

Legend has it that there was a less famous geneticist in the 1800s
NNADVOKAT [17]

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

  • The researcher has total control over the crosses.
  • Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
  • Pea plants may be examined for a greater series of generations than cats or other animals.
  • Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

  • The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
  • Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
  • Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

Describe how a eukaryotic cell can be viewed as four interacting systems: the nucleus, cytosol, endomembrane system, and semiaut
mars1129 [50]

Answer and explanation;

Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.

Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.

Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.

Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.
