Answer:

(Choice B) 555 homologous pairs of chromosomes comprising a total of 202020 chromatids

Explanation:

Homologous chromosome are those two chromosomes which have same gene but different in shape and appearance. Chromatids are the identical copies of chromosome. Single chromosome splits into double number of chromatids. In 555 pairs, 101010 chromosomes are present so 101010 chromosomes splits into 202020 chromatids.

Answer:

Multicellular

Explanation:

Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.

As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.

Does this make sense? Feel free to comment any other questions!! If this explanation helped you, please consider leaving me a good review and/or brainliest!! <3

What is the function of RBC
avanturin [10]

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

The lifetime of an intracellular signaling molecule must be short for the cell to be able to cause a change in the concentration
ivann1987 [24]

Answer:

Statement B is false.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of  polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.
