How do the location and the relative size of the bulbourethral glands of the fetal pig?

Biology

Ber [7]3 years ago
5 0
The location of the bulbourethral glands in the fetal pig is the same as in humans. However, this gland in humans is much larger. 
The main function of the bulbourethral or the cowper's gland is to produce and release the fluid that get rid of any acidicurine in the urethra. The clear fluid neutralizes urine in the urethra so that when a man ejaculates, the sperm in the semen are no destroyed by acidic urine left in the urethra.

Interbreeding two different species of lovebirds produces offspring that are unable to build a nest after they mature because th
Ad libitum [116K]

The question is incomplete and the whole question is-

Interbreeding two different species of lovebirds produces offspring unable to build a nest after  they mature because they lack the innate knowledge needed to carry the nesting materials. The hybrid offspring do not reproduce, and this limits genetic mixing of the two species. This is an example of:

Answer:

The correct answer is- Hybrid infertility

Explanation:

When members of two different species reproduce and produce offspring, then these offsprings are called hybrid. If the hybrid offsprings are not able to produce viable gamete and do not able to reproduce then this is called hybrid infertility. One of the famous examples is mule produce by breeding between donkey and horse.

So here interbreeding of two species of lovebirds produces offspring that do not reproduce and lack innate knowledge needed to build the nest which limits the genetic mixing between the species due to hybrid infertility.

One reason that multiple approaches are often taken to answer a testable question is that scientists
Tju [1.3M]
<span>look at each perspective on how the phenomenon might have took place in a different kind of perspective. Multiple approaches are explored to see which condition fits and answers the query the most -accurate and reliably.

developing a technique for observing an object that has yet to be observed


</span>Thus, to achieve the creative approach above the researchers must utilize and apply the scientific method in gathering, interpreting and analyzing empirical evidence. 

<span>Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process.

"Discuss three factors that affect your daily food choices. For each factor with a negative outcome, suggest at least one change
professor190 [17]

Answer:

Three factors that affect my daily food choices include:

1. Taste

2. Length of time for preparation

3. Method of preparation.

Explanation:

When making choices for food, I tend to take several factors into consideration. Some of these factors include;

1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.

2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.

  • To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.

3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.

  • To turn this around, I hope to employ the help of a family member to make the process easier.
  • I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.

Explain how the fit of the continents can be used as evidence or continental drift
olasank [31]

So, all the continents can combine into a supercontinent we call Pangea. We believe Pangea was formed a long time ago. Because of different world events (earthquakes, fissures,ice melting, the meteor that hit the dinosaurs, etc)this supercontinent split and the continents drifted away eventually forming the modern day topography we know today. We have evidence that Pangea was formed a long time ago because of similar species on different continents that would be too far away to share a common ancestor otherwise. (think about birds being on every continent, they can't have flown all the way across the Atlantic/Pacific)
