A wave hits an object as shown.
Which kind of wave interaction is shown?
Answer:
Refraction
Explanation:
The wave interaction shown is called refraction.
Refraction occurs when a wave crosses the boundary between two mediumIn this process the ray becomes bent. The density difference between the two medium accounts for the bending of the rays. When a ray crosses the boundary from a less dense to a denser medium, it is deflected to the normal as the ray slows down.Answer:
refraction
Explanation:
If an ecosystem is no longer able to sustain its biodiversity, what potential impact could that fact have on the carrying capacity and growth rate of the human population over time?
It could potentially lead to a decrease in the carrying capacity of the ecosystem, which could in turn lead to a decrease in the growth rate of the human population over time.
What is carrying capacity?The carrying capacity of an ecosystem is the maximum number of individuals of a particular species that can be supported by the resources of that ecosystem. It is determined by the availability of food, water, and other resources, as well as by the presence of other species and environmental conditions. When the carrying capacity is reached, the population of that species will stabilize and may even begin to decline.
Carrying capacity is an important concept in ecology and population dynamics, as it determines the maximum size that a population can reach in a particular environment. It is important to note that carrying capacity is not fixed and can change over time due to a variety of factors, such as climate change, the introduction of new species, or the depletion of resources.

Which of the following is true about the Calvin cycle?
Rubisco fixes O2 to a carbohydrate molecule.
Both ATP and NADPH are needed to make sugars.
Light energy is converted to chemical energy.
Answer:
1. ATP - decrease
2.NADPH - decrease
3. sugars - decrease
And True- Both ATP and NADPH are needed to make sugars.
Explanation:
Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.
H+, and oxygen, are formed from a water molecule as it's broken apart. From photosystem II, electrons are transferred to photosystem I. ATP is synthesized from ADP along with inorganic phosphate. To form NADPHH, H+ is added to NADPIf PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.
In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

Figure 1 show the distributions of the two squirrel species in 1945 and 2010.
Answer:
The grey squirrel has increased their rate of emigration to the UK
The grey squirrel has increased their rate of emigration to the UK.
What is emigration?Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).
A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.
Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.
Therefore, The grey squirrel has increased their rate of emigration to the UK.

A ball bounces on the ground. How do the ball and the ground act on each other?
Explanation:
It will continue to fall under the influence of gravitational acceleration, but now, a normal force from the ground surface, opposing the force due to gravity, will act on the ball.This all means that the ball is pushing on the ground with a force greater than its own weight, so acceleration must point upward.

Explain the effect of ingesting an extremely large amount of water at the cellular, including the role of osmosis in this process
Hi, you've asked an incomplete question. Here's the full question:
In extreme cases, it is possible to die from drinking too much water. The consumption of several liters of water in a short amount of time can lead to brain edema (swelling) and death. Explain the effect of ingesting an extremely large amount of water at the level of the brain cells, including the role of osmosis in this process.
Explanation:
Note, the term Osmosis in biology refers to the movement of solvents such as water through a semipermeable membrane to a higher solute (what is dissolved in the solvent) concentrated region.
For example, when one ingests an extremely large amount of water, the osmosis process begins as the water (which is the solvent) would travel down into the cell membrane and then into the cell (which is the semipermeable membrane in this case), because of the imbalance in the concentration the cell/water level, the cell may dysfunction possibly leading to death.
The effect of ingesting an extremely large amount of water at the cellular, including the role of osmosis in this process - It creates a hypotonic environment for your body due to osmosis.
Osmosisa process in which solvent such as water moves from its higher concentration to its lower concentrationIt must be separated by a semipermeable membrane or differentially permeable membraneit does not require any extra energy, only depends on the concentration gradient.When someone ingests an extremely large amount of water at the cellular, water will diffuse into the cell and the cell will begin to swell which is known as a hypotonic environment.Learn more:

Judy used the following soil triangle to identify a sample of soil as silty clay.
Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.
Which description of soil likely allowed Judy to make this identification? (2 points)
a
Mostly large particles, with a gritty texture, 75% clay, 15% sand, and 10% silt
b
Mostly large particles, with a sticky texture, 65% clay, 10% sand, and 25% silt
c
Mostly small particles, with a sticky texture, 50% clay and 5% sand, and 45% silt
d
Mostly small particles, with a smooth texture, 30% clay, and 25% sand, 45% silt
Answer:
its C
Explanation: I worked it our w/ the triangle and this seemed the most logical answer. plus had the same question on a test ~5min before this post so I know for sure its right.
Soil texture or Soil profiling is referred to as the proportion of primarily three different types of particles, clay, sand, and silt.
The description that is similar to Judy's soil triangle is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.
The soil profiling can be explained as:
1. Clay is one of the smoothest and fine particles of the soil. It has a diameter of fewer than 0.2 millimeters. Clay soil is 40% or more is clay, less than 40% is silt, and 45% or less is sand.
2. Sand is a coarse particle and is the largest mineral in the soil. The particle is gritty and has a diameter of 0.05 to 0.02 mm.
3. Silt is found in a high percentage of the soil and gives a smooth texture to the soil.
Thus, the correct answer is Option C.
