what are basics of fungi​

Answers

Answer:

Explanation:

Fungi are heterotrophs and, like animals, obtain their carbon and energy from other organisms.

Answer:

Fungi are a kingdom of mostly microscopic organisms that are closely related to animals. They include spore-producing organisms such as mushrooms, yeast, and molds. Fungi are almost always invisible to the naked eye. Fungi are made up of masses of tubular filaments called hyphae that penetrate and absorb nutrients from the substrates on which fungi grow. Some fungi have extensive networks of hyphae that enable the fruiting body of the fungi to grow very large, such as many species of the shelf, or bracket, fungi

Which of the following effects is least likely to be as a result of deforestation?

A: A greater risk of flooding.

B: An increase in biodiversity.

C: An increase in soil erosion.

D: An increase in the level of carbon dioxide in the atmosphere.

Answers

It would be B, because without the forest there would be no animals which means there wouldn’t be anywhere for an increase in biodiversity

The effect that is least likely to be a result of deforestation is an increase in biodiversity. That is option B.

Deforestation is a practice that encourages the clearing of forests for other purposes such as agricultural croplands, urbanization, or mining activities.

This practice needs to be avoided because:

posses a greater risk of flooding as deforestation erodes the soil.they provide a protective cover for the soil against the action of wind and rain thereby preventing soil erosion.the level of carbon dioxide in the atmosphere decreases as it is cleared by trees during photosynthesis.

But deforestation leads to a decrease in biodiversity instead of an increase.

Deforestation can lead to biodiversity loss. This occurs when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct.

200g of water at 90degree Celsius is mixed with 100g of water at 30 degree Celsius. What is the final temperature (C of water =4.2jkg-1 k-1​

Answers

Answer:

70 °C

Explanation:

Since heat lost by 200 g of water = heat gained by 100 g of water

-mc(T - T') = m'c(T - T")

where m = 200 g,T' = 90°C, m' = 100 g,T" = 30°C and T = final temperature of mixture, c = specific heat capacity of water = 4.2jkg-1 k-1​.

Substituting the values of the variables into the equation, we have

-mc(T - T') = m'c(T - T")

-200 g(T - 90 °C) = 100 g(T - 30 °C)

(T - 90 °C) = 100 g(T - 30 °C)/-200 g

(T - 90 °C) = -0.5(T - 30 °C)

T - 90 °C = -0.5T + 15 °C

collecting like terms, we have

T + 0.5T = 90 °C + 15 °C

1.5T = 105 °C

T = 105 °C/1,5

T = 70 °C
