What is the result of a mutation during meiosis?

Biology
1 answer:
galina1969 [7]3 years ago
4 0

Answer:

A mutation is a change in the nucleotide sequence of the DNA in a cell. ... Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to the genetic variability of the population.

True [87]

The organism which is multicellular and that it first digests, then absorbs nutrients from the environment around it, best fits into the classification of fungi.

Multicellular organisms are those that are comprised of more than one cell in their body. They can either have a loose composition of various cells or have a complete organ-system kind of body. The example include all animals and plants.

Fungi is the kingdom consisting of multicellular eukaryotic organisms. The mode of nutrition in fungi is heterotrophic. It can be of various types like holozoic, saprophytic and parasitic. However the saprophytic mode is more predominant.

Warm surface waters get depleted of nutrients and carbon dioxide, but they enrich again as they travel through ________ waters i
Nonamiya [84]

Answer: Option B. "Deep"

Explanation:

Thermohaline circulation helps to drive the global conveyor belt, which is a global-scale system of currents. Due to the movement of ocean currents through different polar regions, it allows depletion of nutrients and carbon dioxide at surface waters and get enrich again as move through deep waters in the conveyor belt.

Winds in the ocean helps to  drive ocean currents in the upper ocean’s surface and these ocean currents moves below the ocean surface as well. the process that controls the movement of ocean current deep in the ocean is called Thermohaline circulation that  is based on differences in the water’s density,  and controlled by temperature (thermo) and salinity (haline).

Thermohaline circulation forms in the polar regions of Earth. Ocean water in the polar region gets colds that allows the formation of sea ice, which in turn make the surrounding seawater saltier and increases the ice density and sinks. This allows the deep-ocean currents to drive the Global conveyer belt.

The conveyor belt starts from the surface of North Atlantic pole, where seawater become saltier and ice starts sinking.  This deep water heads south along the western Atlantic basin. The conveyor belt get recharged as it travels along the coast of Antarctica and carries more cold, salty, dense water. The current get divided into two different sections, one traveling to the Indian Ocean and the other moves into the Pacific Ocean. The two sections of the current get warm and rises, as they travel northward, then turn back around  westward and southward.

The warmed surface waters continue to circulate around the globe and follows depletion of nutrients and carbon dioxide. But they get enrich again when they travel through deep waters all around the the  Global conveyer belt.

Hence, the correct answer is option is B "Deep".

Galina-37 [17]

Answer;

"couples" energetically unfavorable reactions to ATP condensation in order to drive the reaction toward the required product.

Explanation;

-Metabolic pathways are designed to synthesize necessary cellular reagents as required for cellular and tissue function. To accomplish this, the reaction sequence includes both reactions that are essentially irreversible and reactions that are freely reversible (near equilibrium).

-In most cases, cells use a strategy called reaction coupling, in which an energetically favorable reaction (like ATP hydrolysis) is directly linked with an energetically unfavorable (endergonic) reaction.

Incomplete sentences, describe two differences between amphibians and fish. what are two examples of amphibians
ollegr [7]
1. Amphibians has moist slimy skin meanwhile fish has scales.
2. Fish uses gills for breathing, but amphibians are different. Young ones uses gills, but adult amphibians uses lungs and even skin for breathing.
Examples of amphibians include frogs and toads.
Both fish and amphibians are one of the 5 types of vertebrates under animals. Besides fish and amphibians, other vertebrates includes mammals, reptiles and birds.
