It's a way of protecting the trees, and making sure they survive the winter and beyond. Leaves die during the winter months. If those dead leaves stayed on the trees, and new ones wouldn't grow in their place, the tree would have no way of making food for themselves.
Hope it helps. ☺
Manufactured compounds called <span>chlorofluorocarbons (CFCs)</span>, that were being released into the atmosphere from products that contained them ,were largely responsible for the hole that developed in the earth’s ozone layer. This is why a lot of products containing CFCs such as styrofoam and aerosoles were banned in various countries.
Answer:
Look for cell walls under a microscope. Fungal cells have cell walls, and animal cells do not.
if there are fungal cells in it, its fungus.
Answer:
1/64
Explanation:
The following genotypes were crossed: AaBbCc X+Xr and AaBBcc X+Y
If we asume that the autosomal genes are in different chromosomes, then they will assort independently during meiosis and gametogenesis. In that case, we can use the Multiplication Rule of Probability to obtain the probability of having a specific genotype in the progeny.<u> This rule states that when two or more events are independent, the probability of all them happening at the same time will be the result of the multiplication of the individual probabilities of each event.</u>
<u />
We can separate each gene in the cross to determine the genotypic ratios in the offspring, and then multiply the probabilities of the aaBbCc X+X+ genotypes to obtain the overall probability of having progeny with that genotype.
<h3><u>Aa x Aa
</u></h3>
1/4 AA
2/4 Aa
1/4 aa
<h3><u>Bb x BB
</u></h3>
1/2 BB
1/2 Bb
<h3><u>Cc x cc
</u></h3>
1/2 Cc
1/2 cc
<h3><u>
X+Xr x X+Y</u></h3>
1/4 X+X+
1/4 X+Y
1/4 X+Xr
1/4 XrY
The probability of having offspring with the aaBbCc X+X+ genotype will be: 1/4 × 1/2 × 1/2 × 1/4 = 1/64
Answer:
Biogeochemical cycle is a type of cycle in which water moves through the biosphere or living part of the earth surface.
Explanation:
In this cycle, water moves from the living bodies from a number of processes such as transpiration, breathing and evaporation. Water is very important for all living organisms because about 70 % of the body of living organism is made up of water. Water is a universal solvent so that's why plants takes nutrients from the soil with water. Without water plants are unable to take nutrients from the soil so water plays a key role in the survival of living organisms.
