An abnormal drought combined with an extended period of hot weather can cause a wildfires in some of Earth's biomes. Which biome would be least likely to experience a wildfire caused by these factors?
A
tundra
B
savanna
C
grassland
D
temperate forest
Answer:
The answer is A tundra
Explanation:
hope this helps :)
The tundra, which is frequently damp and covered in ice, can catch fire. Wild land fires do happen and are a normal part of the ecosystem despite the long, harsh winters and brief summers. Thus, option A is correct.
What is tundra biome?Due to a lack of nutrients and the ground being frozen beneath the top layer of soil, very few plants can thrive on the tundra.
The winters are frequently bitterly cold, although the summers can be mild. With mean annual temperatures below 0 °C during six to ten months of the year, tundra winters are protracted, dark, and cold.
Therefore, tundra biome would be least likely to experience a wildfire caused by these factors.

1. Compare neutron stars and black holes.
2. explain the role of white dwarfs in recycling matter
3. Distinguish between an astronomical unit and a light year
4. How does a convection zone transfer energy?
Thanks!
Answer:
1. Both neutron stars and black holes are the corpses of stars that died in explosions known as supernovas. Black holes form when the most massive stars die and neutron stars form when stars not as large die. They both have a very strong gravitational pull, but a black hole's pull is stronger than a neutron star. Neutron stars will turn into black holes if the force of gravity breaks the resistance of electrons.
2. White dwarfs are degenerate, which means they can compress matter. The material in a white dwarf no longer undergoes fusion reactions, so it is supported only by electron degeneracy pressure. This causes it to be extremely dense, saving space and energy.
3. A light year is the distance light travels in a year while an astronomical unit is the average distance between the earth and the sun.
4. A convection zone transfers energy by radiation and conduction.
Waves run through substances, but they do not move the substances in the direction of the waves.
True
False
Answer:
False
Explanation:
Im not 100% sure tho
Waves run through substances, but they do not move the substances in the direction of the waves, and this is true for the first option as the wave transfers energy through the medium, causing the particles to vibrate.
What is the significance of the waves?Waves play a significant role in many areas of science and technology, such as in physics, where they are used to explain the behavior of light; in technology, where they are used for communication, as in radio; and in other fields, such as ultrasound and X-rays, where waves are used for the purpose of imaging.
Hence, waves run through substances, but they do not move the substances in the direction of the waves, and this is true for the first option as the wave transfers energy through the medium, causing the particles to vibrate.

Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

A type of mountain formed when magma collects beneath an overlying rock layer, forcing the layer upward into a blister-like structure is known as a domed mountain.
What is magma?Magma has been defined as the molten or the semi-molten material which is natural and from magma all igneous rocks are formed. Beneath the surface of the earth magma has been found and there are very proofs of magmatism and it has been observed on the other terrestrial planets as well as some of the natural satellites.
Sedimentary rocks are generally made up from directly heat and these are formed when deposition or accumulation of particles that are organic or minerals at the surface of Earth, later followed by the process of cementation. The main feature of sedimentary rock is that they are formed in multiple layers.The rocks are made up of more than one mineral and the size of some rocks are small or big it depends upon their constituents.

Identify three features of the newly formed skin that are different from a healthy patch of skin. Suggest a reason for each of these differences.
Answer:
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The skin has three main functions: Protection; Thermoregulation; Sensation.
The skin acts as a protective barrier from:
Mechanical, thermal and other physical injury;
Harmful agents;
Excessive loss of moisture and protein;
Harmful effects of UV radiation.

Plant hormones are chemical regulators that stimulate or inhibit growth depending on their concentration and type of tissue in which they
are found

STIMULATION
ROOTS
LOW
HIGH
HORMONE CONCENTRATION
Based on the information in the graph, which is a correct conclusion about plant hormones?
F. They stimulate maximum root growth and stem growth at the same concentration.
OG. They stimulate maximum stem growth at low concentrations,
OH. They stimulate maximum root growth at high concentrations.
OJ. They stimulate maximum root and stem growth at different concentrations.
Answer:
OJ. They stimulate maximum root and stem growth at different concentrations.
Explanation:
Looking at the graph found in the attachment below, conclusions can be drawn about the effect ofnthe difference in concentration of plant hormones in the two different parts of the plants under consideration, the roots and the stem.p
Considering the roots;
maximum growth of the roots of plants as seen by the upward curve ofbthe arrow, is obtained when plant hormones are at low concentrations. However, with increase in the concentration of plant hormones, the growth of root diminishes as seen bynthe downward slope of the curve.
Considering the stems:
At low concentration of hoeprmones, the growth of stem is very minimal. However, with increase in concentration of plants hormones, a rapid upward shoot is seen in curve indicating a rapid increase in growth. Maximum growth occurs at high concentration of plant hormones.
Therefore, the proper conclusion is that, plant hormones stimulate maximum root and stem growth at different concentrations.

What is Friction?
It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.
To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.
Therefore, friction can cause a moving object to stop.

An experiment is a type of research method used for scientific investigation to check how a natural phenomenon works and how a particular variable affected by causing or manipulating one variable.
The affected variable called the dependent variable and the variable that is changed is called the independent variable. Other than independent variables other variables should be controlled so there would be no influence on the result other than independent varibles.

Answer:
Differences in air temperature cause movement in the air, which creates pressure.
The radiant energy from the Sun is transferred to the atmosphere, causing air movement. The air becomes less dense, so it rises.
As the air falls, it becomes more dense and cools to Earth’s surface.
The higher the latitude, the colder the climate; the lower the latitude, the hotter the climate.
