Why does diuron cause coral to bleach

Answers

Answer 1

Simple answer:

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.

More in depth explanation:

Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

Hope this helped :)

Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination for a population of plants.

Answers

Answer:

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species  is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water  to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed  from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain  a particular plant would always breed true.

Additionally it prevent  the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get  weak and prone to diseases and infection. Because of poor resistant from lack of variation.

How many grams are in 12 teaspoon of salt if 5.00 grams of salt are in 1.00
teaspoon?

Answers

Answer:

There are 60 grams of the salt in 12 teaspoon of it

Explanation:

We can rephrase the question by saying, if 1 teaspoon has 5.00 grams of salt, how many grams does 12 teaspoon have? We can then equate the answer by doing the following

1 teaspoon = 5 grams

12 teaspoon = ?

Cross-multiply

? = 12 × 5/1

? = 60 grams

There are 60 grams of the salt in 12 teaspoon of it

Decomposition is the process by which:
Carbon atoms are released into the soil
Carbon is converted to CO2
Organisms obtain energy by breaking down glucose

Answers

Answer:

Decomposition is the process by which carbon atoms are released into the soil.

Explanation:

Organic decomposition involves the process of degradation of a living organism by releasing its elemental components.

In the process of decomposition, chemical elements such as carbon are released mainly in the soil, contributing to its enrichment and use by other living beings.

The release of carbon —product of decomposition— to the soil, for recycling, is part of the carbon cycle.

The other options are not correct because:

The conversion of carbon into CO₂ is combustion. Organisms obtain energy by breaking down glucose is part of cellular respiration.

Compare the carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea.


(Note: Needs to be detailed) [this is more of a Geology question]

Answers

Answer:

The carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea is explained below in details.

Explanation:

A mountain stream is a river or stream, normally with a sheer slope, running down a mountainside. Stream velocity is most noted in midstream near the exterior and is crawling along the stream bottom and shores due to friction.

The river stalls down at the entrance, so it doesn't have the energy to carry all the sand, dirt, and clay anymore. These deposits create the flat, regularly triangle-shaped tract of a delta.

What is the probability of producing a roan (red and white) cow when a white cow is crossed with a red cow?

Cross: RR x WW

Answers

Answer:

A cross between a roan bull (Ww) and a white cow (ww) produces roan and white phenotypes in a 1:1 ratio.

Explanation:

Two alleles are influencing the color of the hair of the cow-W red and w white.

These alleles show that a hybrid Ww has red hair. The genotype of the bull is Ww, WW is red and ww is white. So, mixing the red and white cows is 1:1.

Explain digestion Process.​

Answers

Answer:

Each bite passes through several "cells" within the digestive system, and each of them has a specific function in terms of processing uneaten food.

Explanation:

The food begins to be processed in the mouth and prepared for the upcoming digestion process.

Saliva is important for food processing, among other things because it contains the enzyme ptyalin (alpha-amylase), which is responsible for the breakdown of starch and glycogen and continues its activities in the stomach.

Well-chewed food passes through the pharynx to the esophagus. During the swallowing of food, the opening of the trachea is closed, although it is possible that some crumb of food strays and causes a strong cough, which expels the excess from the trachea.

From the esophagus, food comes into the stomach, which is surrounded by ribs. Stomach acid is extremely strong and enables the conversion of food into liquid, which facilitates the further process of digestion.

Food from the stomach continues its way through the digestive tract to the duodenum, from the duodenum it reaches the small intestine.

Food processing in the large intestine is the last phase of digestion of food in the digestive tract. When the waste materials reach it, they need up to 24 hours to pass through the large intestine and reach the other end.
