Not chemistry but I need help. Someone plz answer these

Answer 1

Answer: 9.Each lichen is made up of a fungus (usually an ascomycete) and an alga (green or blue-green). 14.It is a member of the group of diseases known as tinea. 7.Most fungi prefer moist locations, but again there are exceptions, such as the fungi that grow on dried grains. 10.A sac, typically cylindrical in shape, in which the spores of ascomycete fungi develop. 11.A microscopic, club-shaped spore-bearing structure produced by certain fungi. 12.(in ferns and lower plants) a receptacle in which asexual spores are formed. 13.Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol are released into the bread dough, making it rise. 8.Never pick and eat wild mushrooms unless they've been identified by an expert! ... Cooking doesn't make a poisonous mushroom safe. In fact, you can be poisoned by breathing in the cooking fumes from some poisonous mushrooms. Even non-poisonous mushrooms can cause unpleasant reactions in people who are sensitive to them. 6.Saprophytes play an important role in soil biology. They break down dead and decaying organic matter into simple substances that can be taken up and recycled by plants. ... Saprophytic fungi use enzymes to decompose biologic material. Parasitic fungi destroy bacteria and other pathogens.

Why is mitosis a form of asexual reproduction?

Answers

Asexual reproduction involves mitosis. It could be by a number of different ways, but all of them involve making new cells from the ones that are already there.

Note that mitosis is also valuable for repairing damaged tissue, replacing worn out cells, growing, and developing, not just asexual reproduction.

Asexual reproduction does not occur by meiosis.

Final answer:

Mitosis is a form of asexual reproduction because it allows a single cell to divide and produce two genetically identical daughter cells. There is no exchange of genetic material, making the offspring an exact copy of the parent.

Explanation:

Mitosis is considered a form of asexual reproduction because it enables a single cell to divide and produce two daughter cells that are genetically identical to the parent cell. In asexual reproduction, there is no exchange of genetic material, thus ensuring that the offspring is an exact copy of the parent. This is the main reason why mitosis, with its mechanism of copying and separating chromosomes, is classified as asexual reproduction.

For instance, a bacterium reproduces by mitosis; first, it duplicates its DNA and then divides into two cells. Each of these two cells has exactly the same DNA as the parent bacterium.

A 440.0 g piece of copper is dropped into 400.0 mL of water at 20.00 °C. The final temperature of the water was measured at 35.80 °C. Calculate the initial temperature of the metal. (SCu = 0.3850 J/gC)

Answers

Answer:

207.50°C

Explanation:

Mass of metal (M1) = 440g

Volume of water = 400mL

Initial temperature of water (T2) = 20°C

Final temperature of the mixture (T3) = 35.80°C

Specific heat capacity of the metal (C1) = 0.3850J/g°C

Specific heat capacity of water = 4.184J/g°C

Density of water = 1g/mL

Temperature of metal (T1) = ?

Heat lost by the metal = Heat gained by the water

Q = MC∇T

Q = heat energy

M = Mass

C = specific heat capacity

∇T = change in temperature

M1C1(T1 - T3) = M2C2(T3 - T2)

M2 = ?

Density = mass / volume

Mass = density * volume

Mass = 1g/mL * 400mL

Mass = 400g

M1C1(T1 - T3) = M2C2(T3 - T2)

400 * 0.3850 (T1 - 35.80) = 400 * 4.184 * (35.80 - 20)

154(T1 - 35.80) = 1673.6 * (15.8)

154T1 - 5513.2 = 26442.88

154T1 = 26442.88 + 5513.2

154T1 = 31956.08

T1 = 31956.08 / 154

T1 = 207.50

The initial temperature of the metal was 207.50°C

Who used experiments and scientific tools to study matter?

Answers

John Dalton used experiments and scientific tools to study matter

Final answer:

Chemists and Physicists use controlled experiments and scientific tools like microscopes and spectrometers to study the chemical and physical properties of matter.

Explanation:

Scientists, particularly Chemists and Physicists, are the ones who use experiments and scientific tools to study matter. They conduct controlled experiments to investigate the physical and chemical properties of different types of matter. For instance, they utilize scientific tools such as microscopes, spectrometers, and calorimeters to measure, observe, and analyze matter at various levels. By using these tools, scientists are able to gather precise and reliable data to better understand the composition, structure, and reactions of matter.

In a model of Earth's layers that is determined by physical properties, how might the atmosphere be classified? Would it be part of the lithosphere or a seperate layer?

Answers

Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps.
