Can Hippodamia convergens and Hippodamia variegata can mate and produce fertile offspring? Explain your answer.

1 answer:

8 0

Hippodamia convergens and Hippodamia variegata can mate but cannot produce fertile offspring because the number of chromosomes can make the development of the embryo unfeasible.

<h3>What are fertile hybrids?</h3>

The crossing between plants or animals of similar species can generate beings that, despite being hybrids, are fertile, even though in the initial phase of cell multiplication some chromosomes do not find the respective pair.

<h3>Why don't hybrids reproduce?</h3>

These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male is necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies.

With this information, we can conclude that Hybrid animals are beings from genetic crosses between different species, but of the same genus, that is, when two different animals cross and a new animal appears, usually sterile, due to their incompatible genes: the hybrid animal.

Describe ways that a human society's culture, agricultural practices, and health practices would be shaped by living in an area

Pachacha [2.7K]

Active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

<h3>What are active volcanoes?</h3>

Active volcanoes are geological formations that have regular cycles of eruptions, releasing liquid magma to the Earth's surface.

These eruptions are composed of rocks (or ash weathers) that generate fertile soils, but also may affect the respiratory airways.

Volcanic eruptions have devastating consequences for human populations and lead to destruction as well as societal collapse.

In conclusion, active volcanoes can affect the properties of the soil (e.g., pH) and therefore may alter agriculture and health.

If you are really stressed out about an upcoming math test on Tuesday what type of stress is this? A: avoidance B:acute C:chroni

Kobotan [32]

Some students feel distressed only in test situations. They might be said to suffer from Acute Stress.

Answer: Option B

<u>Explanation:</u>

Stress is your body's reaction to specific circumstances. It's abstract, so something that is distressing for you may not be unpleasant for another person. There is a wide range of sorts of stress and not every one of them is terrible. Stress can enable you to act rapidly in a crisis or help you comply with a time constraint.

Acute stress is the most widely recognized sort of pressure. It's your body's prompt response to another test, occasion, or request, and it triggers your battle or flight reaction.
