Clams that are native to China are living in the San Francisco bay. How can these clams damage the bay ecosystem?​

Answers

Answer 1

Answer:

Marine Invasive Species are animals or algae that have been translocated from their native region to California marine and estuarine waters. Invasive species are also called introduced, exotic, alien, nonindigenous or non-native.The introduction of NIS can cause harm to the ecosystem by displacing native species, becoming a human health dangerby introducing new diseases, or cause economic havoc on commercial, agricultural, or recreational activities by clogging waterways, and impacting navigation and recreation.

A prime example of the harm an invasive species can cause is Caulerpa taxifolia, also known as Killer Algae, a strain of green seaweed believed to be released from an aquarium directly into a water body or through a storm drain. The Killer Algae forms a dense carpet on any surface including rock, sand, and mud displacing native plants and animals, disrupts the natural food chain, and seriously impacting recreational and commercial fisheries.

Although Caulerpa was successfully eradicated from California marine waters, few eradications have been attempted due to perceived challenges and high cost (over $7M was expended in the case of Caulerpa).

Number of Invasive Species Statewide

The map below shows that all major harbor areas and Bays in California have received significant NIS introductions. San Francisco Bay has the highest number of non-native species, followed by the Ports of Los Angeles/Long Beach. San Francisco Bay is a hotspot for invasions because it has high recreational boating and commercial shipping traffic, a history of oyster culture, and is adjacent to a highly urbanized area. Our research found that San Francisco Bay is a hub for the spread of NIS to the rest of the West Coast.

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?

Answers

Answer:

186

Explanation:

The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130  bp + (14 bp x 4) = 130 + 56 = 186.

The DNA sequence CAT would be transcribed into which mRNA codon?

Answers

it would transcribe into GUA

Answer:

GUA

Explanation:

Hello There!

These are the base pairs for transcription

IMPORTANT

when transcribing; Adenine transcribes to Uracil not Thymine

so it would be

Adenine to Uracil

Thymine to Adenine

Cytosine to Guanine

Guanine to cytosine

so we want to find the mRNA codon of the dna sequence CAT

Cytosine to Guanine (G)

Adenine to Uracil (U)

Thymine to Adenine (A)

your answer is GUA

Compare and contrast suspension feeding and deposit feeding-

Answers

Answer:

Suspension feeding involves collecting food particles like small organisms, organic matter, detritus which are suspended in water, often using some form of filtration.

Suspension feeders catch food or organic material from the water using tentacles or spiny arms

where as

Deposit feeding involves feasting on detritus and organic matter that have settled on the ocean floor.

Deposit feeders pass sand, mud, water or sediment into their mouths using mucous-covered tentacles or arms etc.

Explanation:

Suspension feeding ingests the food particles which are suspended in water, while deposit feeding ingests sediments and aquire foods.

What do you mean by Deposit feeders?

Deposit feeders may be defined as those aquatic organisms that forage on organic matter that settled down on the bottom.

Suspension feeding maintains the water quality in the aquatic environment, while deposit feeding enhances oxygen level and nutrient cycling.

Suspension feeding occurs similarly to filter-feeding that only ingests suspended particles. While deposit-feeding ingests the deposited particles like detritus, organic matter, etc.

Therefore, it is well described above.

The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.

What is horizon?

The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.

What is event?

An event would be the collection of results from an experiment.

B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.

C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.

D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.

The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.

Explanation to the difference in the cellular vacuole size:

When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.

hence, the correct option is d.

1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?

Answers

Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.
