Which of the following will occasionally produced a duplicate gene

Answer:

The correct answer is spilling breaker.

Explanation:

The spilling breaker is also known as surf wave is an over-steepened wave in which the unsteady top of the wave tumbles down the front of the waveform as it progresses towards the shallower water. This results in a gradual reduction of the height of the wave unless it moves up the beach as swash.  The kind of wave, which arises from a moderately sloping coastal region will be a spilling breaker, as it is a common wave related to moderate beach gradient.

Answer:

Plunging Breaker

Explanation:

There are three types of "normal waves". The Surging breaker is when the beach has a steep slope, the spilling breaker is when the beach is almost perfectly flat. That leaves the plunging breaker, which is a wave that occurs when the beach is moderately flat. Hope this helps!

Nutrients from fertilizers, such as nitrogen and phosphorus, can be harmful to aquatic ecosystems primarily because they promote excessive growth of algae and aquatic plants. Hence option b "The increase in algae population reduces oxygen in the water" is correct.

This excessive growth is known as eutrophication. The process unfolds as follows:

Nutrient Input: Fertilizers with nitrogen and phosphorus are often utilized in residential and agricultural settings. These nutrients may be introduced into surrounding water bodies by runoff from these locations.

Algal Blooms: Nutrients function as fertilisers for algae and aquatic plants, causing algal blooms. Algal blooms are therefore created as a result of the fast growth in the population of algae. These blooms can completely cover the water's surface, turning it green or murky.

Oxygen Depletion: The process of decomposition consumes oxygen when the algae and aquatic plants die and degrade. An higher need for oxygen results from the large amount of organic material from the deceased organisms. As a result, the amount of dissolved oxygen in the water may decrease.

1. cilia-----------paramecium

Paramecium is one of the least complex unicellular creatures, which is found in all water body related ecological conditions.  

The cilia assume a key job in paramecium development.  

Paramecia are single-celled microorganisms that live in freshwater and marine conditions. They have a place with the phylum Ciliophora, the ciliated protozoa. A cilium is a short, hair-like structure that projects from a life form's cell layer. A paramecium has a large number of cilia that musically beat, giving an approach to it to move around and to clear sustenance into its oral score.

2. flagellum---------euglena

Euglena are unicellular living beings grouped into the Kingdom Protista, and the Phylum Euglenophyta. All euglena have chloroplasts and can make their very own sustenance by photosynthesis. They are not totally autotrophic however, euglena can likewise retain sustenance from their condition; euglena normally live in calm lakes or puddles.  

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that demonstrations like somewhat engine. The flagellum is situated on the foremost (front) end, and whirls so as to pull the cell through the water. It is appended at an internal pocket called the store.

3. pseudopodia--------amoeba

Amoebae utilize pseudopodia (signifying "false feet") to move. This is essentially a similar way phagocytes (a sort of white platelet) immerse an attacking microorganism when we battle a disease. On account of a single adaptable cell moving, it's cytoplasm streams forward to frame a pseudopodium, at that point it levels pull out. With the end goal to eat, it will shape two pseudopodia and wrap those around to meet one another, encasing its sustenance, at that point the cytoplasm levels out once more.

Answer: False

Explanation:

There are two types of reproduction asexual reproduction and sexual reproduction. Bacteria performs binary fission which is a asexual mode of reproduction.

In this process a single bacterial cells divides into two and it is exactly the same as like of their parent cell. Genetically and phenotipically, the daughter cell is same as like that of the parent cell.
