Morphine combined with alcohol can produce _____ effects
soldier1979 [14.2K]
The answer that best completes the statement above is DEADLY. Mixing morphine and alcohol can have deadly effects. We know that morphine is a type of pain killer. How this works is by influencing how the brain perceives pain. On the other hand, alcohol is a depressant. Mixing both can result in lack of coordination, impaired judgment and motor skills. Since the body is too depressed, this may result in coma or death.

What is the purpose of the uninoculated control tubes used in the oxidation fermentation test? why is it necessary to use two co
Vitek1552 [10]

<u>Answer</u>:

1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.

2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.

3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.

Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen.  This tube will show that the medium is unaffected by the lack of oxygen.

The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.

Finch species living on the Galapagos Islands exhibit a variety of beak types that favor different foods. Finches that eat seeds
Setler [38]

Explanation:

<u>B) There is an abundance of seeds and nuts.</u>

The finches have developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.  Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.

Which best describes oogenesis and spermatogenesis?
pochemuha
The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>
