Answer:
The ecological effects of acid rain are in aquatic environments, such as streams, lakes, and marshes prove destructive to fish and other wildlife. Acid rain seeps into the soil, and harbors aluminum from soil clay particles that flow directly into streams or lakes. Acid rain affects aquatic environments in this way, because it can kill fish, which reduces fish populations, ultimately eliminating fish species in a waterbody and decreasing the available biodiversity. Competition for food increases and disrupts the equilibrium of the aquatic environment.
a rocket is fired straight upward from ground level with an initial velocity of 480Km)hr. After t second , its distance above the ground level is given by 480t-16t^2. For what time interval is the rocket more than 3200Km above ground level?
Answer:
answer
Explanation:
The rocket is 19.5 m above the ground when h=19h=19:

The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25
0.75≤t≤3.25
The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.
What is quadratic equation?To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.
We can start by setting the equation for the rocket's distance above the ground level equal to 3200:
We can then solve this equation for t using the quadratic formula
[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]
Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

Explanation:
The first species to arrive are fast-growing “weedy species,” such as lichens or small annual plants, which create the first layers of soil as they decompose.
Answer:
B. Pioneer
Explanation:
The pioneer group is the first species to arrive in ecological succession. Hence, option (B) is the correct answer.

Sami had low birth welght as a lamb but quickly grew into a large sheep.
Answer:
D. Sami had low birth weight as a lamb but quickly grew into a large sheep.
Explanation:
The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.

Explanation:
Has the change in the environment (in this case the food preference of predators) caused natural selection to start occurring in this fish population?
Answer:
Yes.
Explanation:
Yes, change in the environment conditions leads to the initiation of natural selection in this fish population if the food preference of the predators changes because changes in the food preference of predator causes lowering of population which can't be eaten by the predator earlier. Changing rainfall and drought patterns reshaping the population and existence of fish by availability of type of food to predators which ultimately leads to natural selection among population of fish.

Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

Colorblindness is an X-linked recessive disorder. If Abby has normal vision (but her father was colorblind) and Ryan is not colorblind. What are the chances that their daughter is colorblind? SHOW ALL WORK FOR CREDIT. (To insert a table in your answer if necessary click on the three dots, click on the icon that looks like a table and you can customize the number and type of boxes you need)
Answer:
Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.
Since Abby's father was colour blind, Abby must be a carrier for the same.
Which means Abby's genotype would be ‘XXᶜ’.
Now, Ryan is not colourblind which means his genotype would be ‘XY’.
Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.
Which means she wouldn't be colourblind but she might be a carrier of the disorder.
XXᶜ × XY
⬇️ ⬇️
X, Xᶜ X
↘️ ↙️
XX , XXᶜ
Their daughter will have either XX genotype or XXᶜ genotype.
And her chances of being colourblind thus, becomes zero.
what is a difference between a lens and a mirror
Answer:
hi
Explanation:
The lens is a material made of glass or plastic bounded by two surfaces. ... A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.
have a nice day
Answer:
The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.
