The correct answer is C.

The egg sinks in freshwater because it is more dense than the water. So, to make the egg float, you would have to increase the density of the water. Since salt water has a greater density than freshwater, you would add salt to the freshwater, thus causing the egg to float rather than sink.

Where do DAG and IP3 originate?
cupoosta [38]

Answer:

Option (4).

Explanation:

Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.

The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.

Thus, the correct answer is option (4).

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death ________ whereas
Aliun [14]

Answer:

time; point

Explanation:

The complete question is as follows:

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.

time; point

window; point

point; time

time; temperature

  • When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
  • The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
  • The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
  • Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.

A woman with brown eyes, which has two brothers, marries a man with brown eyes, which has a brother and two sisters, and produce
cupoosta [38]

Answer:

A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.

Complex sugars are called _____. A) monosaccharides B) disaccharides C) polysaccharides
Brums [2.3K]
Complex sugars are called polysaccharides. The correct answer is C. The Latin prefix poly- means many, so the entire name of this saccharide means that there are many atoms of sugar in it, which makes it a complex sugar. Di- in disaccharide means 2, and mono- in monosaccharide means 1, neither of which is complex.
