Answer:

The correct answer will be option-leaves

Explanation:

Cactus is a xerophytic plant which is adapted to grow in the dry conditions or low amount of water.

They show adaptation to growing in the extreme conditions by modifying their leaves into the spines to prevent the loss of water and stems to become photosynthetic and storing the water. Their leaves become microscopic and the spines are arranged in clusters.

Thus, leaves are the correct answer.

Answer:

The correct answer is leaves, spines are modified leaves.

Why does the Department of Homeland Security target foot-and-mouth disease?
Zinaida [17]

The bottom- and- mouth complaint contagion has been honored since at least the 16th century.

  • It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.

  • Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.

  • The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.

  • FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint. With one in nine Americans employed in the husbandry or confederated diligence, the goods of an FMD outbreak in the U.S. would be ruinous ­ – estimated at nearly$ 200 billion in lost profit over 10 times across affected diligence.

Therefore the Department of Homeland Security target foot-and-mouth disease.

Which of the following is a characteristic of vitamin D nutrition?​a.​Pigments in dark skins increase vitamin D synthesis. b.​On
Anvisha [2.4K]

Answer:

b.​ Only about one-half of the world's population relies on sunlight to maintain adequate vitamin D nutrition  

Explanation:

Dark skin pigments slow down the synthesis of vitamin D, so black people need to spend more time in the sun to absorb enough vitamin D, so the letter A is incorrect.

Prolonged exposure to sunlight degrades the precursor of vitamin D, whereas prolonged exposure to sunlight produces vitamin D3, which acts to regulate heart function and blood pressure.  With this we can conclude that the letter C is also incorrect.

Vitamin D deficiency is not caused by calcium deficiency, on the contrary, vitamin D deficiency is a cause of calcium deficiency. In addition, summer vitamin D synthesis stocks are usually not sufficient to meet summer vitamin D requirements. That is why the letter D is also incorrect.

We can conclude, then, that the correct answer is the letter B. The main source of vitamin production is through sun exposure, because type B ultraviolet rays (UVB) are able to activate the synthesis of this substance. Some foods, especially fatty fish, are sources of vitamin D, but the sun is responsible for 80 to 90% of the vitamin the body receives. It can also be produced in the laboratory and given as a supplement when there is a deficiency and for the prevention and treatment of a variety of diseases.
