which of these describes what happens when the temperature of an object increases
Answer:
kinetic energy
Explanation: When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

An analysis of rock types in the area of the Acadia National Park shows a variety of geology in the region. Which evidence would support the theory that rocks in the area of the national park were formed from previous volcanic activity? Select ALL that apply.
A) the presence of igneous rocks
B) the presence of sedimentary rock
C) the presence of metamorphic rock
D) the presence of carbonate rock types
E) the presence of granite rock features
The presence of igneous rocks and granite rock features would support the theory of previous volcanic activity.
If an analysis of rock types in the area of the Acadia National Park shows the presence of igneous rocks and granite rock features, it would support the theory that the rocks in the area were formed from previous volcanic activity.
Igneous rocks are formed from the solidification of magma or lava, which are products of volcanic activity.
Granite is a type of igneous rock that forms from the slow cooling and solidification of magma beneath the Earth's surface.
The presence of sedimentary, metamorphic, or carbonate rock types would not support the theory of previous volcanic activity because these types of rocks are formed through different processes, such as sedimentation, heat and pressure, and chemical reactions.

Answer:
Macro-capsule: thickness of 0.2µm or more, visible under light microscope
Microcapsule: thickness less than 0.2µm, visible under Electron microscope
Explanation:
It has several functions: promote bacterial adhesion to surface or interaction with other organisms; act as a permeability barrier, as a defense mechanism against Phagocytosis and/or as a nutrient reserve. Among pathogens, capsule formation often correlates with pathogenicity
correct me if I'm wrong
Answer:
Capsule (also known as K antigen) is a major virulence factor of bacteria, e.g. all of the principal pathogens which cause pneumonia and meningitis, including Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Klebsiella pneumoniae, Escherichia coli, and group B streptococci have polysaccharide capsules on their surface. Nonencapsulated mutants of these organisms are avirulent.

Several species of finch live on the Galapagos Islands. They are very similar in appearance, but have adapted beaks of different sizes and shapes based on their major food source. Finches with large beaks eat mainly large seeds and cacti. Finches with small beaks eat mainly small seeds and insects. Which of the following best explains the variety of beaks found in finches on the Galapagos Islands? A. Evolution through natural selection always causes a decrease in the species diversity of an ecosystem. B. Biological evolution does not have any effect on the species diversity of an ecosystem. C. Biological evolution only affects the species diversity of plants in an ecosystem. D. Evolution through natural selection can increase the species diversity of an ecosystem
Answer:
D is the correct answer
Explanation:
Evolution by natural selection can only act on traits initially present. In the common ancestor, there would have been one beak, but in the offspring, there would have been variation in beak size and shape. As natural selection acts on that variation, different species end up with traits adapted to different conditions, thus increasing the species diversity.

what process will you see to recover salt, which has dissolved in water?
Answer:
What process will you use to recover salt which has dissolved in water?
Explanation:
You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

How many millimetres (equivalent depth) of water are
contained in a soil profile 1 metre deep if the mass water
content of the upper 400 mm depth is 15% and that of the
lower 600 mm is 20%. The bulk density in the upper layer is
1300 kg m- and in the lower layer is 1500 kg m-?. Assume Pw
= 1000 kg m’How much water does the soil contain (in
cubic
metres) per 1.5 hectares of land?
ri
The equivalent depth of water in the soil is 270 mm and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.
How can equivalent depth of water in a soil be calculate?The equivalent depth of water in a soil is calculated using the formula below:
equivalent depth of water = water content × depth of soilThe depth of soil profile 1 = 1 m = 1000 mm
The depth of soil profile 2 = 600 mm
Equivalent depth of water in the soil = 15% × 1000 mm + 20% × 600 mm
Equivalent depth of water in the soil = 150 mm + 120 mm
Equivalent depth of water in the soil = 270 mm of water
The volumetric water content of the soil is calculated using the formula below:
Volumetric water content = water content × bulk density of soil/density of water × height of soilHeight of soil profile 1 = 1 m
Height of soil profile 2 = 0.6 m
Volumetric water content of soil profile 1 = 15% × 1300/1000 × 1 m = 0.195 cubic meter/square metre of soil
Volumetric water content of soil profile 1 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil
Total Volumetric water content of soil = 0.18 + 0.195 = 0.375 cubic meter/square metre of soil
Converting to cubic meter/hectare of soil:
0.375 cubic meter/square metre of soil
1.5 hectares = 15000 square metre
Volumetric water content of soil = 0.375 × 15000 cubic meter/ 1.5 hectare of soil
Volumetric water content of soil = 5625 cubic meter/ 1.5 hectare of soil
Therefore, the equivalent depth of water in the soil is 270 mm of water and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.

Vascular tissue allows a plant to transport water
against the pull of gravity. Which statement best

kingdom?
A. All plants use vascular tissue to transport water.
B. Most plants, but not mosses and other bryo-
phytes, use vascular tissue to transport water.
C. Only woody plants, such as trees and shrubs,
