Creating a Bottleneck Effect in an Ostrilope Population in the Sim
Goal: In fewer than 30 generations, change the starting ostrilope population into a population of at least 70 individuals with low variation in color traits (4 traits or fewer). Do this without adding a predator.
Do:
Decide on a strategy to reduce the variation of the ostrilope population.
Open the Natural Selection Simulation and open the mode: Color Change Mission.
Try out your strategy by making any changes in either Build or Run.
Use the histograms in Analyze or the Traits Histogram Window in Run to see if your strategy was successful.
Tips:
You can modify abiotic factors in Run at any time by pressing the Abiotic Factors icon in the lower-right corner of the screen.
Do not make any changes to the starting ostrilope population settings.
Return to Build and press REBUILD to reset the Sim to the default settings.

Here is what you and the women see when you look through the electron microscope. What is your conclusion about whether polio is a virus, and why? What would you recommend for polio prevention?
Answers
Explanation:
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. I believe this is a virus because virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
my recommendation for polio prevention is Poliomyelitis vaccine should be given at 2, 4, and 12 to 18 months and 4 to 6 years of age, for a total of four doses at or before school entry. For children who receive OPV only, the third dose may be given as early as 6 months of age in accordance with prior recommendations.

Answer: 1st part Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire
2nd part plant tropisms are mechanisms by which plants adapt to environmental changes. Thigmotropism describes plant growth in response to touch or contact with a solid object. Positive thigmostropism is demonstrated by climbing plants or vines, which have specialized structures called tendrils. Gravitropism or geotropism is growth in response to gravity.
Answer:
2)During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.
Phototropism is the orientation of a plant or other organism in response to light, either toward the source of light.
Thigmotropism is the turning or bending of a plant or other organism in response to a touch stimulus.
Gravitropism is a coordinated process of differential growth by a plant in response to gravity pulling on it.

Bees help pollinate flowers and in return, the bees get nectar to eat. If the bee population declines, then the population of flowers will also decline. Which of the following statements best describes the impact of a decline in the bee population?
A. It represents a biotic factor affecting the flower population in a negative way.
B. It represents an abiotic factor affecting the flower population in a negative way.
C. It represents a biotic factor affecting the flower population in a positive way.
D. It represents an abiotic factor affecting the flower population in a positive way.
Answers
Answer:
A
Explanation:
Explanation because biotic means living things and flowers are living things. Also if the bees decline then the flowers decline in a negative way because they have nothing to eat.

What are Rock Layers?
Strata, the plural of the Latin term stratum, is another name for rock layers, and stratigraphy is the study of strata. Stratigraphy is the study of the features of stratified rocks, including their relationship to time.
The majority of the rocks that are visible at the Earth's surface are sedimentary, meaning they were created from fragments of older rocks that were blown apart by wind or water.
In rivers, lakes, and seas, the gravel, sand, and muck sink to the bottom. Sand turns into sandstone, muck turns into mudstone or shale, gravel turns into conglomerate, and plant and animal fragments can turn into fossils.
Therefore, Cuba would make no sence due to the problem.

- T-Rex were extinct 65 million years ago during the K-T mass which was caused by asteroid colliding with Earth.
- No, because I don’t think it’s possible to prevent an asteroid hitting Earth. The immediate blast would have killed them no matter where the impact had occurred.
- T-Rex lived in humid tropical environment, with open forest and near rivers.
- T-Rex have big heads with forwarded eyes, strong jaws with teeth, tail which helped them with balance, and they also have powerful back legs for speed.

2 circles with an overlap. The left circled is labeled Longitudinal Wave with further labels parallel motion, like moving a spring up and down. The right circle is labeled Transverse Wave with further labels perpendicular motion, like moving a spring back and forth. In the overlap are labels particles only move a small amount, particles do not move with the wave.
Venn diagrams are used for comparing and contrasting topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. This Venn diagram is comparing longitudinal waves and transverse waves.
Where is the error in this Venn diagram?
“Parallel” and “Perpendicular” are switched.
The spring descriptions of motion are switched.
Particles travel along the wave in longitudinal waves.
Particles move long distances in transverse waves.
Answers
Answer:
B.The slinky descriptions of motion are switched.
Explanation:
First of all, let's define the two types of wave:
- Transverse wave: in a transverse wave, the oscillation of the wave occurs in a direction perpendicular to the direction of propagation of the wave. An example of transverse wave are electromagnetic waves.
- Longitudinal wave: in a longitudinal wave, the oscillation of the wave occurs in a direction parallel to the direction of propagation of the wave. An example of longitudinal wave are sound waves.
According to these definitions, we notice that the following descriptions of motion must be switched:
- "Like moving a spring up and down" --> this better describes a transverse wave, because the motion up/down is perpendicular to the direction of the spring
- "Like moving a spring back and forth" --> this better describes a longitudinal wave, because the back/forth motion is parallel to the direction of the spring
Explanation:
Have a great day
The spring descriptions of motion are switched. Therefore, option B is correct.
What are waves and their types?A disturbance that moves or propagates away from its source is referred to as a wave. While waves can move energy from one location to another, they do not always move mass. Common examples of waves include ocean waves, light waves, and sound waves.
Mechanical waves can move in either longitudinal waves or transverse waves, which are the two most common wave motions. The two forms of waves are shown in the videos below, which also show how the movement of the wave differs from that of the particles in the medium it travels through.
Thus, the error in this Venn diagram is that the spring descriptions of motion are switched. Therefore, option B is correct.

Which inherited characteristic will a toucan pass on to its offspring?
A: A colorful beak
B: Black fur
C: The ability to sing
D: The skills to build a nest
Answers
A colourful beak is an inherited characteristic a toucan will pass on to its offspring. Therefore, option (A) is correct.
What are inherited characteristics?
Inherited characteristics are traits or features that are passed down from parents to offspring through genes. Genes are segments of DNA that code for specific traits, such as eye color, height, and hair texture. Inherited characteristics can be physical, such as eye color, or behavioral, such as the ability to fly or swim.
They are determined by the combination of genes inherited from both parents, and may be dominant or recessive. Dominant traits are expressed when a person has one or two copies of the gene, while recessive traits are only expressed when a person has two copies of the gene. Inherited characteristics play a key role in the process of evolution by natural selection, as they determine which traits are more likely to be passed on to future generations.
