How does a tree move substances like water and glucose around?
Answer:
Most plants have green leaves, where the photosynthesis happens. When those sugars are made, they need to be given to every cell in the plant for energy. Enter phloem. The phloem cells are laid out end-to-end throughout the entire plant, transporting the sugars and other molecules created by the plant.

why don't people get the smallpox vaccine anymore?
Answer:
After world health authorities declared smallpox had been eradicated from nature in 1980, Wyeth stopped making the vaccine. The U.S. Centers for Disease Control and Prevention (CDC) kept a stockpile for use in case of emergency. In 2003 this supply helped contain an outbreak of monkeypox in the United States.

What happens if there is a mutation in the DNA? What are the effects of a mutation?
Answer:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

There are two continents with an ocean between them. Today, the continents have very diferent plants and animals on
them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago when
this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue
that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take
for this to happen?
Answer:
It took hundreds and thousands of year and earth quakes and sea level rise have drowned some island parts and split the land and took it somewhere else
Explanation:
When the land got split apart some fossils were in the splitting of the land and got separated apart from each other this also helps with the history of our planet and what happened

If a species has 35 % adenine in it’s DNA what is the percent of the other three bases
Answer:
35% thyamine, 15% guanine and 15% cytosine
Answer:
35% thymine, 15% guanine and 15% cytosine
Explanation:
35% thymine, 15% guanine, and, 15% cytosine because the exact same amount of thymine would pair up with adenine, thus thymine has to be 35%. Thymine and adenine take up 70% of the DNA the rest has to equal 30%. Guanine and cytosine make up the rest, which is 30%, thus we have to split it evenly because they pair up with each other. Therefore, guanine and cytosine equal 15%.

Answer:
3. Spiral galaxies revolve around a single point and gas spinning arms of stars extending from the center
4. Star 4 will stay on the main sequence for the longest time.
Explanation:
A galaxy is a system of gases, dust, and billions of stars and their solar systems, and dark matter which are bound together by gravity. Types of galaxies based on structure are elliptical, spiral, irregular and barred spiral.
Spiral galaxies have a spiral shape consisting of a central bulge, a halo, a disk, and spiral arms. At the center of revolution of the galaxy is the bulge which contains older stars. The disk contains gas, dust and younger stars which extend as spiral arms. The halo is found around the bulge and contains old cluster of stars. Ab example of a spiral galaxy is our Milky Way galaxy.
4. The mass of a star is related to its luminosity as well as its position on the main sequence. High solar mass stars have high luminosity and therefore spend the least time on the main sequence whereas low solar mass stars have low luminosity and spend the most time on the main sequence.
Therefore, Star 4 having the lowest solar mass will spend the most time on the main sequence.

Describe the impact of human activity on natural resources - (discuss resources such as energy, minerals, forest and marine include overpopulation and over fishing)
Answer:
As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas
Explanation: Hope this helps! ^^
Answer:
Overpopulation can result in a/an
scarcity

how can we determine the probability that an organisms expressed version of a trait will be passed on to it's offspring?
Answer:
Punnet square
Explanation:
I am pretty sure this is it
By using Punnett square we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.
What is Punnett square?Reginald. C Punnett invented the Punnett square, a square shape diagram used to forecast the genotype and phenotype of offspring from a breeding experiment by crossing the genes of the parents.
The diagram's number of Punnett squares is determined by the number of attributes employed. After creating the boxes, one parent's gene is placed on top and the other parent's gene is placed on the left side.
In the event of a monohybrid cross, just one letter with a single characteristic crosses one box, whereas two letters with two separate traits cross one box.
The number of alternative genotypes of offspring is obtained by crossing the characteristic.
Thus, the Punnett square helps in determining the probability that a trait will be passed on to its offspring.

what stages of the cell cycle are included in interphase
Answer:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
