Which of the following offspring genotypes could result from the fertilization of an egg that had undergone nondisjunction in me

Lorico [155]

Answer:

See explanation below

Explanation:

<em>Non-disjunction occur as a result of lack of separation of homologous chromosomes during meiosis. </em>

As a result, the gametes (the daughter cells formed) produced end up having extra or lesser chromosomes as compared to a normal gamete.

When a gamete with extra chromosome fertilizes a normal gamete, the resulting offspring will have an extra chromosome (trisomy condition).

On the other hand, when a gamete with one less chromosome than normal fertilizes a normal gamete, the resulting offspring will have one less chromosome than normal offspring (monosomy condition).

Assuming a chromosome with Aa gene undergoes non disjunction during meiosis, the resulting gametes either contain both A and a chromosome or contain no chromosome at all.

If Aa gamete is fertilized by a normal haploid sperm (a), the resulting zygote will have the genotype Aaa.

If a gamete with no chromosome at all fertilizes a normal haploid sperm, the resulting offspring will have the genotype a.

In most cells, there are electrochemical gradients of many ions across the plasma membrane even though there are usually only on

devlian [24]

Answer:

The correct answer is option A, that is, cotransport proteins.

Explanation:

The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.

The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.

guajiro [1.7K]

Answer:

Fungi, Animalia, Plantae, and Protista

Explanation:

Fungi: A cluster of organisms that produce spores and feed on organic matter, examples are Mushrooms, mold and yeast.

Animals: a classification of living organisms that almost always have organs, and feed on other organic matter, they also usually have a nervous system. Examples are, Pigeons, Lions, Whales, etc.

Plants: organisms such as grass, trees, moss, flowers, and grow in the same spot. They absorb water, and inorganic matter through their roots, and usually have green coloring to do photosynthesis.

Protists: These organisms are usually microscopic and unicellular. They contain a nucleus and other specialized organelles, and some can move around. They vary widely of what they do, with some like Amoebas moving and eating other cells, while algae stay put and perform photosynthesis.

How do you think humans might affect the environment? Check all that apply. by adding greenhouse gases to the atmosphere by usin

OLEGan [10]

The correct answers are <span>by adding greenhouse gases to the atmosphere by using natural resources, by polluting the land, water, and air, by creating landfills and by introducing invasive species to the environment.

Adding greenhouse gases to the atmosphere contributes to the rise of the global temperature and climate change which leads to the rise in sea level, and extreme weather conditions.

By polluting the land water and air and creating landfills humans are destroying not only the habitat of many plants, animals, and other organisms but also for themselves.

Overexploitation of the natural resources also leads to the destruction of habitat and collapse of ecosystems.

The introduction of invasive species often leads to disruption of the food chain of an ecosystem since the invasive species might be more efficient in this habitat and suppress the native organisms.
