Animals can be engineered to require less food, grow quicker, and leave behind less evironmentally damaging waste.
-Animals can be engineered to be more resistant to harmful and painful diseases.
-Animals can be engineered to produce more omega-3 fatty acids, to provide leaner meat, and to make more milk.
-Animals can be engineered so their tissues, organs, and cells can be transplanted into humans.
-Animals can be engineered to produce certain substances that offer a new source of medicine.
-Animals can be engineered to reproduce much faster.

negative impacts.

It is unethical.
-Some food companies have refused to use meat or milk that is from genetically engineered animals.
-Some consumers are complaining that the animal drug rules do not regulate genetically modified animals properly.
-This process is potentially dangerous and can be very harmful.
-When engineering animals the natural ecosystem can be disturbed.
-Some animals die in experiments while other are born deformed or huge.
-Animals may live in odd comditions that are affect their natural way of life.
-Most injected eggs do not end up creating a living animal.

The _____ is the serous membrane that covers the abdominal organs.

lina2011 [118]

The abdominal cavity is lined by peritoneum. It is a membrane that covers the inner layer of the cavity and also the organs inside. The membrane on the inner wall is parietal Thperitonium and the membrane that lines the organ is called visceral peritoneum. This helps in fixation and support of abdominal organs.

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first

jek_recluse [69]

Answer:

D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.

Explanation:

Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.

However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.

Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
