Answer:
First, there is only one type of DNA! ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made. There is a complication that some amino acids have more than one code which specifies it - there are plenty of examples where a change of codes (eg a mutation) can result in NO CHANGE in the amino acid which is specified. Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit.

Which statement is not an example of how the use of resources has changed?
A. More products are made from recycled materials.
B. Cars still largely rely on oil.
C. Car companies have developed hybrid cars.
D. More wind farms are present in the United States.
Answer:
B. Cars still largely rely on oil.
Explanation:
Nowadays, most countries still use transportation systems that burn fossil fuels. An example of this may be private cars that consume gasoline, which derives from fossil fuels (oil). The use of fossil fuel transportation systems increases the emission of carbon dioxide (CO2), a major greenhouse gas involved in global warming. In the near future, it is expected that fossil fuel-based vehicles can be replaced by electric cars that use energy obtained from renewable sources (e.g., solar energy, wind energy, etc).
Answer:
B is not correct. I know cause I took the test here are the correct answers!
Car companies have developed hybrid cars.
More wind farms are present in the United States.

Some fire extinguishers contain liquid carbon dioxide.
Suggest how carbon dioxide gas can be changed to liquid carbon dioxide without
reducing its temperature.
Answer:
:)
Explanation:
The CO2 Extinguisher Cannisters contain carbon dioxide in liquid form, and when the extinguisher is let off the liquid is released into the air neutralising the oxygen that the fire is feeding on, disabling the fires ability to spread.
i think its what you want :)
neutralising-make (something) ineffective by applying an opposite force or effect.
What phase of mitosis is shown in the picture above?
A. Metaphase
B. Anaphase
C. Telephase
D. Prophase
The phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.
What is Mitosis?Mitosis may be defined as the type of cell division in which two daughter cells are formed from a parental cell with the exact number of chromosomes.
In metaphase, the chromosome usually lines up in one plane and forms an equatorial plate in which they are attached to the spindle fiber through their centromere.
Therefore, the phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.

Explanation:
Plant cells contain a cell wall while animal cells do not have a cell wall. By looking for the presence of a cell wall, students would be able to positively identify a cell as either plant or animal.
Maya Is a carrier for albinism, a recessive tralt that results in the absence of the skin plgment melanin In halr and
eyes. She marries Jack, and they have four children: Zach, Olivia, Sophla, and Veronica. Veronica expresses the
tralt for albinism, but her three siblings are unaffected by the recessive tralt.
Draw a pedigree that Illustrates the famlly's tralts, and upload your pedigree.
Answer:
The correct answer is as follows:
Explanation:
In this given question, Maya is a carrier for albinism which express in presence of two copies of a recessive gene and after marriage with Jack she has 4 children among three are normal and one has albinism which suggests that the ratio of the albinism in this family is 3:1 phenotypically.
Maya - Aa (heterozygous carrier)
Jack - AA or Aa
cross between two
A a
A AA Aa
a Aa aa
this cross showing that the jack is heterozygous for the condition as the result are the same as given in question 3:1
what is the difference between DNA of a stomach cell and the DNA of a brain cell?
Answer:
they have different functions
Explanation:
the stomach cells breakdown food and make up a certain tissue and take nutrients from the food you eat while the brain cell makes up your neurons and receptors
Since they both have the same genetic information stored in the same sequence of nucleotides, the DNA of a stomach cell and the DNA of a brain cell is practically identical. However, there may be functional distinctions between both kinds of cells depending on how some genes are expressed.
What happens during development?Cells specialize during development and differentiate into various cell types with distinct functions. According to the requirements of the cell, specific genes are turned on or off as part of the differentiation process.
For instance, a brain cell may express genes that enable it to relay messages and make connections with other cells in the nervous system, whereas a stomach cell may express genes that allow it to produce digestive enzymes and absorb nutrients.
Therefore, the DNA of a stomach cell and the DNA of a brain cell is nearly identical since they both have the same genetic information stored in the same sequence of nucleotides.

How can you explain the difference in number of mitochondria in these types of cells?
Answer:
Organs which need alot of energy to function properly have a greater number of mitochondria
Explanation:
Mitochondria are sites for respiratory enzymes which yield energy for the cells thus skeletal muscles which need alot of energy have more mitochondria than liver and liver due to doing more activities than skin has more mitochondria than the skin.
Answer:
Skeletal muscle cells have a very high amount of mitochondria as well as liver cells because they need high amounts of energy to carry out their functions, whereas skin cells don't need high amounts of energy to function.

how do mutations lead to genetic diversity?
The mutation Mutations are changes to an organism's DNA and are an important driver of diversity in populations. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

How are mutations and meiosis similar?
Answer:
Mutations can occur before,during and after mitosis and meiosis if a mutation occurs in cells that will make gametes by meiosis or during meiosis itself it can be passed on to off spring and contribute to genetic variability of the population.
may be this was ur answer of ur question.
Mutations and meiosis are in that they both produce genetic variation
in organisms.
Meiosis is a type of cell division that involves the production of sex cells or in sexual reproduction. They produce unique daughter cells and in situations where there is a mutation in this process, it is usually passed to the offspring which leads to genetic variation.
Mutations are also usually passed to the daughter cells as it occurs in their
cells during reproduction which makes it similar with meiosis in the area of
genetic variation.

What would happen if the rate of evaporation reduces
Answer:
