guajiro [1.7K]

This is called an epidural. A procedure that delivers continuous pain relief to the lower part of your body while allowing women to remain fully awake. It decreases sensation of pain. The medication is inserted into the epidural space just outside the spinal cord and spinal fluid. This is the most common method used in the United States.

Helo! i was wondering if anyone could help me of these two questions for biology?

Rom4ik [11]

1) A 2) B

Explanation:

Enzymes are catalyst, meaning that they could be use in several reaction and they speed up any chemical reaction rate. So knowing this, when the animal have more enzymes it will react more quickly with the food, making it digest the food more quickly.

Hope the help, cheers

Which of the following would be a good adaptation for an organism that lives in the intertidal zone?

barxatty [35]

The right answer is A.

The foreshore, also called intertidal zone, is the tidal zone of the tides on the coast. The alternation of the tides which discover more or less the substrate according to the phases of the Moon determines the conditions of humidity, salinity and temperature of the foreshore.

These variations lead to a vertical ecological structuring of the foreshore in so-called supralittoral, mediolittoral and infralittoral stages. The floristic and faunistic stands of these stages are distinct, according to the requirements of organisms in water, salinity and temperature. Therefore it would be beneficial for organisms living in this period that it can live without depending on the water present in their environment since the presence of the latter is inconstant.

The foreshore is divided into several floors that correspond to different ecological conditions. These coastal stages are defined by the duration of their emergence and therefore by the level of the different tides.

Predict phenotypes associated with nondisjunction of sex chromosomes.

Mnenie [13.5K]

Answer: The new daughter cells will have an abnormal amount of genetic material. That is called aneuploidy and it is the presence of an abnormal number of chromosomes. Different clinical conditions are the result of this nondisjunction.

Explanation:

Normal cells are diploids, that means they have two copies of each gene, one of each chromosome. So normal cells have two homologous chromosomes, one from each parent.

During anaphase of cell division, each pair of chromosomes is separated by the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell, and eventually will end up in the new daughter cells.

Nondisjunction is the failure of homologous chromosomes to separate properly during cell division, so it is the miss segregation of them. The new daughter cells will have an abnormal amount of genetic material. Different clinical conditions are the result of this nondisjunction.

Sex chromosomes participates in sex determination of an individual. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY) So nondisjunction of sex chromosomes could be:

XX: one cell with no chromosome and the other cell with two X chromosomes.
XY: one cell with no chromosomes and the other cell with XY chromosomes.

According to which gametes are fused during fertilization, different phenotypes can be given. For example, if a gamete with one chromosome fuses with another gamete with two chromosomes, the result will be an individual with three chromosomes (it could be XXY, or XXX) called trisomy.

Triple X syndrome is characterized by an extra X chromosome in females. Those affected are often taller than average, but most females have a normal sexual development. Klinefelter syndrome is known XXY individuals, and it causes infertility in males, breast growth, less body hair and weaker muscles.

And if a gamete with no chromosome fuses also with another gamete with no chromosome, the result is a nullisomy. But due to the lack of genetic material, the nullisomic gametes are rendered unviable for fertilization.

And if a gamete with no chromosome fuses with another gamete with one chromosome (normal) the result is a monosomy, the presence of only one chromosome from a pair. The result can be an individual who is X or Y. People with Turner syndrome have one X chromosome and it is the only monosomy that is seen in humans because other cases monosomy are lethal.

Any of those examples is called aneuploidy and it is the presence of an abnormal number of chromosomes.

5. What is harmful at ground level but absorbs ultraviolet radiation from the sun in its natural

Morgarella [4.7K]

Answer:

Ozone.

Ozone occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays.
