Answer: Acid rain is a product of the <u>chemical reaction of sulfur dioxide and nitrogen oxide that is released with water, oxygen, and other chemicals into the atmosphere.</u> <u>Sulfur dioxide and nitrogen oxide dissolve in water and can be carried several miles by the wind</u>. After traveling for a long distance,<u> the two compounds become part of rain, sleet, snow or fog.</u> <u>Power plants emit sulfur dioxide and nitrogen oxide when fossil fuels such as coal are burned to produce electricity.</u> Aswell as <u>the exhaust from cars, trucks, and buses releases sulfur dioxide and nitrogen oxide into the air.</u>
Answer:
A scale and a tape measure.
Explanation:
Use the tape measure to get the volume and the scale to get the mass.
Answer:
It is a seeded vascular plant.
It does not depend on insect pollination.
Explanation:
The complete question is: <em>A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.
</em>

<em>The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.</em>
Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.
Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
