The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.

They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again. They find that the colder temperature showed a high pressure in the tires and that the pressure decreased after the tires were able to warm up.
C.
The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.
D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.

20. Frigatebirds have webbed feet and spend much
of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?
Answer:
Evolution changes the abilities of the Frigate birds.
Explanation:
The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.

How does a new mammoth egg cell get chromosomes from each of the parents?
Answer:
An egg or sperm only has half of the parent's sex chromosome pair. An egg will always have an X chromosome, since the woman's sex chromosome pair only has Xs. Sperm can have either an X chromosome or a Y chromosome. If a sperm with an X chromosome fertilizes the egg, the new cell will have two X chromosomes. One came from the father's sperm and one came from the mother's egg. Since the sex chromosome that is made is XX, the cell will grow into a girl baby.
Explanation:
Hope this helped Mark BRAINLIEST!!
mixing occur before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.
What is chromosome ?A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

Briefly explain how an animal's role in the agricultural industry determines its most desirable traits as livestock
Answer:
The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

8. Two heterozygous purple flowered plants are crossed.
What percentage of the offspring are purple?
white?
Answer:
75% chance of purple, 25% of white
Explanation:
Heterozygous means having two different alleles of a gene
This must mean they are Purple dominant and white recessive
This will be represented as Pw
[tex]\left[\begin{array}{ccc} &P&w\\P&PP&Pw\\w&Pw&ww\end{array}\right][/tex]
This, called a punnet square, calculates the probability of the gene outcome. The top Pw represents one parent and the Pw on the left side represent the other.
In the diagram, each combo of letters ( PP, Pw, Pw, ww ) represents a 25% of what gene the offspring will have. PP means it'll be purple, and so does both Pw's. ww means white flowers though because there is no dominant trait and only recessive. This is the only way for a recessive trait to appear in a child.
Therefore there is a 75% chance of the offspring having purple flowers and a 25% chance of the offspring have white flowers.
