A fungus kills 75% of the plant life in tropical areas such as Florida, Mexico, Central America, and the Bahamas. These areas include plants that do not go into a dormancy, like in New England, and a significant percentage of global rain forests. Would might be the global result as it relates to: photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.
Answer:
Yes, it affects photosynthesis rate, amount of atmospheric carbon dioxide, and ecosystem balance.
Explanation:
Plants have the ability to clean the environment by absorbing carbondioxide gas during the process of photosynthesis. These plants are the important part of ecosystem and their removal causes imbalance of ecosystem. These plants provide habitat and food etc. If plants were killed because of fungal attack so decrease occurs in rate of photosynthesis, concentration of carbondioxide gas in the atmosphere and disturbed the balance of ecosystem.

Is it the male or female that determines the sex of a zygote? Based on chromosomes, how do we know this to be true
Answer:
The male
Explanation:
A female always gives one X chromosome, a male can give either an X or a Y. If a zygote receives an X from its father and another X from its mother, it will be female. If a zygote receives a Y from its father and an X from its mother it will be male. Because the mother only has one option of chromosome to give, her chromosomes will not effect the gender of the zygote.

The equation of line e is y = 3/5x + 1. The equation of line f is y = -8/3x + 9/8. Are line e and
line f parallel or perpendicular?
Answer:
I think they're neither perpendicular nor parallel
Explanation:
Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)
Not perpendicular since the product of their slopes isn't equal to - 1.
=> (3/5)(-8/3)= - 8/5 and not - 1
(plz make sure you typed the equations correctly.)

Why do researchers think that seals use visual cues to
navigate?
Answer:
Their vision underwater is better than a humans, but inferior on land. Lenses are enlarged and almost round, adapted for focusing on light that is refracted upon entering water. They use the light to continue swimming which is why researchers think they use visual cues because of how quickly they react to the amount of light in the water

In a certain population of rabbits, the allele for brown fur is dominant over the
allele for white fur. If 20 out of 100 rabbits have white fur, what is the allele

The Hardy-Weinberg equation is:

A. 0.45
B. 0.80
C. 0.89
D. 0.65
In a certain population of rabbits, the allele for brown fur is dominant over the allele for white fur. If 20 out of 100 rabbits have white fur, the frequency of the recessive allele (b) is 0.45. Therefore, the correct statement is option A.
What is Hardy-Weinberg law?Hardy-Weinberg law represents the relationship between the allele frequency and genotypes present in the population.
If the allele controlling brown fur is dominant over the allele controlling white fur, the Hardy-Weinberg equation can be used to calculate the frequency of the recessive allele.
Let the frequency of the dominant allele (B) is denoted by p and the frequency of the recessive allele (b) be denoted by q. If 20 out of 100 rabbits have white fur, which means that the frequency of the bb genotype is 20/100 or 0.2.
Using the equation, we know that: p^2 + 2pq + q^2 = 1
where p^2 represents the frequency of the BB genotype, 2pq represents the frequency of the Bb genotype, and q^2 represents the frequency of the bb genotype.
By substituting the knowing values, the value of q can be calculated:
0.2 = q^2
q = sqrt (0.2) = 0.45
Therefore, the frequency of the b recessive allele is 0.45.

Using the images below, draw how plants and animals depend on each other.
Answer:
Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal.
Explanation:
Answer: Plants and animals rely on each other for many things. One idea is that plants are a food sources for animals that are herbivores such as a rabbit. The animals that eat those herbivores, like a fox, are carnivores. Plants perform photosynthesis which is crucial to the survival of every organism on the planet including us humans. Through photosynthesis plants provide a source of energy and a release of oxygen. Plants can also be a habitat for other species. The CO2

or carbon dioxide that animals exhale is a key ingredient for photosynthesis. Another way animals benefit plants is that when they die they decompose and put organic matter and nutrients back into the soil for plants to use. Animals can also help a plant disperse it's seeds or act as pollinators.

Which would be the best way to measure the amount of loose rabbits on a farm?
A) count them all
B) Trap-mark-release
C) Sample count
D) Estimated guess
Answer:
Estimated Guess so D because if there are more then 10 rabbits you do not want to count every single one. So you would look at how many five are and see how many groups look like about 5 and then guess from there. So an estimated guess would quickly and easily get you a decent amount close to counting them.
Hows that for an answer.
