Answer:

The research is unethical(fetal stem cells) since the blastocyst, an unimplanted human embryo at the sixth to eighth day of development, is destroyed during the stem cell extraction process.

Answer:

Embryonic Stem Cell Disadvantages

1. Difficult to differentiate uniformly and homogeneously into a target tissue. 2. Immunogenic—ES cells from a random embryo donor are likely to be rejected. after transplantation.

Explanation:

The main disadvantage with embryonic stem cells is the way that they are acquired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.

The process of elimination of nitrogenous waste from the body

scZoUnD [109]

Answer:

Excretion

Explanation:

The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. When cells break down proteins, they produce nitrogenous wastes, like urea. The excretory system serves to remove these nitrogenous waste products, as well as excess salts and water, from the body.

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then dr

inn [45]

The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.

Answer: YES, SUPPORTED

Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.

These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.

In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).

________ is the proportion of dissolved salts to pure water.

Dafna11 [192]

<span>The proportion of dissolved salts to pure water in the ocean is known as salinity. This is commonly measured in parts per thousand. For example, if the salinity of an ocean is 35 parts per thousand, or ppt, this means that in every kilogram, or 1000 grams, of ocean water, there are 35 grams of salt present. The higher the quantity of parts per thousand, the saltier the water, which also means the higher the salinity.</span>
