Summarize the water cycle
Answer:
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
Little brown bats are a species of bat in the genus Myotis. Little brown bats are extremely common in North America, where they roost in houses, buildings, or trees. In the winter, the bats hibernate in caves, unused mines, or other similar locations. Unfortunately, little brown bats are threatened due to white-nose syndrome. Given these terms related to bats, match the term to the level of biological organization.all little brown bats
Answer: population: The bat species of North America
community : a little brown bat
organism: bat
Explanation:
Here, the population of the bat resides in the North America in the houses, trees and buildings they hide in the caves in winters for hibernation. Inside the cave they form a bat community here the organism is bat. These bats are threatened in numbers due to white nose syndrome. The white nose syndrome is the fungal growth on the wings and muzzles of the bats. The fungus affects the bats during hibernation, when the bats trying to save their energy by reducing their metabolic rate. It is transferrable from one bat to another thus can infect the entire population of bat. It is a dangerous disease.

If 800 offspring were produced from the cross, in what numbers would you expect the following phenotypes?
__wild type : __ miniature wings : __ garnet eyes : __ miniature wings, garnet eyes
Enter your answer as the number of flies of each phenotype separated by a colon (example: 100:300:100:300).
Answer:
Part A:
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
Part B:
32:368:368:32
Explanation:
When calculating the recombination frequency, we need to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, only one results in a recombinant one.
So, en the exposed example:
PART A:
First, we need to Identify the gametes for the individual with the genotype m + g / mg + and label parental and recombinants
Gametes:
m+ g parental type m g+ parental type m+ g+ recombinant typem g recombinant typeKnowing that the only possible gamete type for the other parental is mg, then we can identify the phenotypic classes of the offspring that were generated as a result of a crossover event. These would be
2. wild type (m+g+/mg)
4. miniature wings, garnet eyes (mg/mg)
PART B:
We know that the total number of individuals equals 800.We also know that the distance between genes equals 8 MU.To calculate the number of the phenotypes among the offsprings,
8 map units = 8% of recombination in total
= 8/2% m+g+/mg + 8/2% mg/mg
= 4% + 4%
The recombination frequency of m+g+/mg equals 0.04
The recombination frequency of mg/mg equals 0.04.
100% - 8% = 92% of parental in total =
= 92/2% of m+ g/mg + 92/2% m g+/mg
= 46% + 46%
The recombination frequency of m+g/mg equals 0.46
The recombination frequency of mg+/mg equals 0.46.
The frequency for each ggenotype is:
F (m+g+/mg) = 0.04 F (mg/mg) = 0.04. F (m+g/mg) = 0.46 F (mg+/mg) = 0.46.The number of individuals with each genotype is:
m+g+/mg = 0.04 x 800 = 32mg/mg = 0.04 x 800 = 32m+g/mg = 0.46 x 800 = 368m g+/mg = 0.46 x 800 = 36832 wild type : 368 miniature wings : 368 garnet eyes : 32 miniature wings, garnet eyes

A plant with a hybrid genotype for red flowers is crossed with a plant that is purebred recessive for white flowers. What percentage of the offspring
should have white flowers?
. 100%
75%
50%
25%
Answer:
50%
Explanation:
If you use a punnet square with Rr x rr you will get 50% white
50% of the offspring should have white flowers when we cross a hybrid genotype for red flowers with pure recessive for white flowers shown in the Punnett square. So, the correct option is C.
What is Punnett square?Punnett square is defined as the diagram that represents the possible genotypes of the offspring developed after a reproductive event. It was first developed by geneticist Reginald Punnett where the possible genotypes of the offspring are represented in a tabular form with each box in the table representing an event of fertilization.
For above given example,
Rr genotype represents the red flowers.
rr genotype represents the white flowers.
The Punnett square will be:
R r
r Rr rr
r Rr rr
So, 50% have red flowers while 50% have white flowers.
Thus, the correct option is C.

What are two examples of adaptations used by animals that live in aquatic biomes?
Answer: Common oceanic animal adaptations include gills, special breathing organs used by some oceanic animals like fish and crabs; blowholes, an opening on the top of the head that's used for breathing; fins, flat, wing-like structures on a fish that help it move through the water; and streamlined bodies.
Explanation: Hope this helps :)
The two examples of adaptations used by animals that live in aquatic biomes are gills and webed feet. The correct option is D.
What is adaptation?A structural adaptation is one that is physically a part of the organism. Another type of adaptation is behavioural, which modifies how an organism reacts to its surroundings.
Aquatic animals have adapted by, among other things, having stream-lined bodies that make swimming easy for them.
Their respiratory system is made up of gills. Fish have many different types of fins, including pectoral, and caudal fins, which serve as their locomotory organs.
There are two different kinds of aquatic ecosystems: freshwater and marine. These aquatic adaptations include: inside human bodies, there are specific air spaces.
The fins are present. Oil droplets on microscopic plants keep them floating.
Thus, the correct option is D.

In one experiment, the heart rate of a mollusk at rest was measured at 0.3 cycles/s. How many times did the mollusk's heart beat in 1 min?
Answer:
18 times
Explanation:
Heart rate = 0.3 cycles/s
Heart rate = [tex]\frac{number of cycles}{time}[/tex]
number of cycles = heart rate x time
But, 1 min = 60 seconds
⇒ number of cycles = 0.3 x 60
= 18
Thus, the number of times that the Mollusk's heart beat in 1 min is 18.
Which one of these is not a human effect on the water cycle?
Developed areas prevent soil from absorbing rainwater
Precipitation is increasing in deserts due to an increase in water use
Air pollutants also wash back into the land and water bodies from precipitation
Storm water runoff carries pollution
Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:
Just see for yourself
The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.
