Answer:
Explanation:
At least 136 wolves were killed in the park between 1914 and 1926. By the 1940’s wolf packs were
seldom reported in the park. In fact, by the mid-1900’s wolves had been nearly eliminated not just from
Yellowstone but from the lower 48 states entirely.
Reintroduction was not without controversy as there were, and still are, many stakeholders involved in the
Yellowstone area, each with unique concerns. However, in the twenty years since the reintroduction of the
wolves, scientists have noticed many positive changes to the park ecosystem. This set of activities seeks to
introduce students to the trophic cascade that has occurred in the park and the positive changes in the
ecosystem since the reintroduction of a top predator – the wolf.

1.Consider the four demographic characteristics relating to biotic potential
listed in the text: (1) usual number of offspring per reproduction, (2) chances
of survival until age of reproduction, (3) how often each individual
reproduces, and (4) age at which reproduction begins. Relate each factor to
the human population, rating each one as contributing to a high or low biotic
potential, justifying each rating. Then decide overall if humans have a high or low biotic potential
low biotic potential.
Answers
Based on the four demographic characteristics relating to biotic potential, humans generally have a low biotic potential.
What is biotic potential?Biotic potential refers to the maximum reproductive capacity or potential of an organism under optimum environmental conditions.
The demographic characteristics relating to biotic potential are:
usual number of offspring per reproduction- it contributes to low biotic potential because humans usually produce one offspring per reproduction chancesof survival until age of reproduction - contributes to high biotic potential since humans have high chances of survivalhow often each individual reproduces - contributes to low biotic potential since humans have usually reproduce at least once every nine months age at which reproduction begins - contributes to a low biotic potential since humans begin to reproduce at a later age of at least 12.Therefore, humans generally have a low biotic potential.

What is the crop plant that is suitable for this biofertilizer? Please elaborate.
Answers
Answer:
In nature, there are a number of useful soil micro organisms which can help plants to absorb nutrients. Their utility can be enhanced with human intervention by selecting efficient organisms, culturing them and adding them to soils directly or through seeds. The cultured micro organisms packed in some carrier material for easy application in the field are called bio-fertilisers. Thus, the critical input in Biofertilisers is the micro organisms.

Sound waves are produced when something is caused to reflect. vibrate. slow down. get warmer.
Answers
Answer:
B) Vibrate
Sound is created through vibration.
Sound waves are produced when something is caused to vibrate. When an object vibrates, it creates a disturbance in the surrounding air molecules, causing them to bump into each other and create a wave of pressure fluctuations. Hence option B is correct.
What are sound waves?Sound waves are a type of mechanical wave that transfers energy through oscillations of particles in a medium such as air, water, or solid material.
When an object vibrates or moves, it sets off a series of pressure waves in the medium around it, creating a disturbance that travels through the medium as sound.
The sound wave consists of compressions and rarefactions of the medium, where compressions are areas of high pressure and rarefactions are areas of low pressure.
The frequency of the vibration determines the pitch of the sound wave. For example, a higher frequency of vibration produces a higher-pitched sound, while a lower frequency produces a lower-pitched sound. The intensity of the vibration determines the volume or loudness of the sound wave.
Hence option B, vibrate is correct.

Identify how the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes.
Answers
The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
What is the relationship between histones and DNA?Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.
How does DNA compact with histones?Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.
Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
