Answer: increases the speed of impulse transmission

Explanation: The advantage of having special sensory organs confined to the head region is that it can help us process the impulses into information faster. A lower risk of damage due to the short distance of the nerves is also an advantage of having sensor organs near the head region. However if one gets a head injury it can be dangerous since the injury may damage the sensory organs, and can take a long period of time to fully recover.

The answer to this question would be: rapid impulse transmission.

By having organ near the head, the brain can process the information faster because the length of the nerve that carries the impulse from organ would be much shorter. The nerve also at lower risk of damage since it was shorter.
But it makes the head very important and damage to the head can cause much more problem than any part of the body.

Science uses data to describe the findings of an experiment. Qualitative Data is:

kirill [66]

Scientific data refers to the information collected by using the scientific method. These data can be obtained from experimental and/or observational procedures.

There are two types of data: qualitative data and quantitative data.

Qualitative Data is a set of data describing the findings of an experiment (Option B).

On the other hand, quantitative data refers to the set of measurements/numbers collected in an experimental or observational procedure.

Suppose there are two homologous chromosomes. Each chromosome contains a single mutant allele in different parts of the chromoso

Harlamova29_29 [7]

Answer:

Cross overs can lead to formation of chromosome pairs that have no mutant allele.

Explanation:

Cross overs can lead to formation of chromosome pairs that have no mutant allele.

For example -

Suppose "X" is a mutant allele and "x" is a mutant free allele.

Now when two homologous chromosomes contains a single mutant allele in different parts of the chromosome are crossed the following offspring are produced

X x

X XX Xx

x Xx xx

"xx" is a mutant free genotype.

Thus, crossing over can create a single mutation-free chromosome

Place the following steps of endomembrane system function in the correct order.

maks197457 [2]

Answer:

Explanation:

The correct option here would be D.

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

Ribosomes on the RER synthesize proteins.
Proteins are packaged into transport vesicles.
Golgi apparatus receives transport vesicles from the RER.
Proteins are modified by the Golgi apparatus.
Modified proteins may be secreted from the cell by exocytosis.
