what is the water intake of chlorophytes​

Answers

Answer:

Huge amount.

Explanation:

There is higher water intake of chlorophytes​ because the chlorophytes prepare their own food by using water and carbondioxide just like plants in the process of photosynthesis. These chlorophytes have chlorophyll which able these algae to make their food from sunlight and they can't live without water of dry places. Chlorophyte is also known as Prasinophyte which is a green algae. So due to photosynthesis, the chlorophytes needs high amount of water for making food.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?

Answers

Answer:

It transport oxygen from lungs to the cells.

Explanation:

The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

From a study of soapberry bugs, evolution can be observed. Soapberry bugs feed on fruits by using their 'beak' to penetrate the fruit and gain nourishment from the seeds within the fruit. Soapberry bugs can feed on the fruit of the balloon vine or the fruit of the Goldenrain tree. In central Florida, the native balloon vine has become rare and the Goldenrain tree is now the main food source for soapberry bugs.
When the beak length of the soapberry bug populations feeding on different fruits was measured after many generations, a difference was noted.
Which of these statements predicts the outcome of evolution based on the food sources for the soapberry bugs? Select ALL that apply.

bugs with longer beak, bugs with shorter beaks, access to the seeds

Buds with larger beaks, shorter beaks, and access to seeds predict the outcome of evolution based on the soapberry bugs' food sources. So, the correct options are A, C and D.

What are Soapberry bugs?

Soapberry bugs are true bugs who survive on the seeds that grow in the Sapindaceae family. They are distributed throughout the Americas, starting with the southern United States to Argentina.

The body structure and colors of soapberry bugs make them easily identifiable. They are distinguished by their flat bodies and a large, pointed beak or rostrum for piercing the fruit and extracting the seeds. Although their colouring varies, several species have a vivid orange-red or black and white colour pattern.

Because they have been the focus of substantial investigation into rapid evolutionary change, soapberry bugs are essential in the investigation of evolution and natural selection.

Therefore, the correct options are A, C and D.
