ways to raise money to support their efforts
D.
the predator populations that eat cane toads
Answer:
B
Explanation:
It isn't D because Cane toads have no natural predators, and it isn't C because there isn't a solution, but B offers a solution that would work since they share some of the same environments.

Find out about the destruction of therain forests in South and Central America. At what rate isthis precious habitat being destroyed? How many species ofplants and animals live in this region, and how many wouldbe threatened? Obtain up-to-date figures from an unbiasedsource, and use the species-area relationship to make moreprojections on how many species will become extinct in therain forests if current rates of habitat destruction continuefor the next 50 years. Create a line graph to show the rate ofextinction for these groups: insects; mammals; birds; trees;flowering plants; nonflowering plants; reptiles; amphibians.

what is the possible Genotypes and the Possible Phenotypes
Answer:
possible genotypes are - Rr Rr Rr Rr
Possible phenotypes - remember that R is dominant therefore all of the seeds with be round
Explanation:
If round pea shape is dominant to wrinkled pea shape, which of the following genotypes
would produce the wrinkled phenotype?
A.RR
B.Rr
C.rr
Answer:
C. rr
Explanation:
The dominant genotype will always be denoted by the capital version, or in this case R.
The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.
The last box, rr, would be the one that gives the wrinkled phenotype.
In this case, by ratio, wrinkled phenotype show up 25%
by ratio, round phenotype show up 75%.

The major disadvantage of this non renewable resource is the disposal of radioactive waste. Group of answer choices Coal Petroleum Natural Gas Nuclear Energy
Answer:
nuclear energy
Explanation:
Nuclear energy is a type of non renewable energy source. It's greatest disadvantage is radioactive wastes disposal.
Radioactive wastes are wastes that contains materials that are radioactive. These wastes are due to different activities in nuclear science. Like nuclear medicine, weapons, nuclear power etc. The wastes can be classified into high level wastes and low level wastes.
True or False. The source of all clouds and precipitation is water vapor.
The technology in the picture produces which energy conversion?
What are the products of cellular respiration? Next to each material identify whether it is organic or inorganic.
Answer:
Organic molecules have more chemical potential energy than inorganic molecules
Explanation:
Chemical molecules can either be organic or inorganic depending on whether they contain certain elements. Organic molecules are molecules that contain in their structure a carbon-hydrogen bond (C-H) e.g C2H4, C6H12O6 etc. while inorganic compounds do not contain the carbon and hydrogen elements bonded together e.g CO2, H2S
Considering the substances/compounds involved in photosynthesis and respiration, glucose (C6H12O6) is the only organic compound while every other compound is inorganic. However, organic compounds store more potential energy called chemical energy in its C-C or C-H bonds than inorganic molecules do.
Answer:
Oxygen and Glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP, waste products include carbon dioxide and water.
Explanation:
Why is the mass of herbivores smaller than the mass of plants?
Answer: The total mass of plants combined is way more then the mass of animals. Animals cannot make their own food so they must eat plants and/or other animals.
How is photosynthesis and cellular similar, and how are they different?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Question 1: How does the body structure of each of these organisms contribute to a particular function?
Question 2: How do structures in living organisms SIMILAR to structures of nonliving things such as a construction cranes, buildings, ships, airplanes, or bridges?
Question 3: How do structures in living organisms DIFFERENT from structures of nonliving things such as a construction cranes, buildings, ships, airplanes, or bridges?

He walked 5 units south and met his friend Joshua. After that, he walked 2 units east and there he bumped into his friend Ethan.
At what location on the coordinate grid did Sam meet Ethan?
OA. point (-3,5)
B. point (-1,-3)
Oc.
point (-3,-5)
O
D. point (-3,-1)
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

After you finish at the store you drive back south on ashland toward your house for 1 mile you stop for gas after about 0.1 hours before you get home
Answer:
hello your question is incomplete below is the missing part
What is your velocity in miles per hour on your way to the gas
station? Hint: Remember that your starting point is 2 miles from your house to the North
answer : 10 miles/hour
Explanation:
Velocity = displacement / time
displacement = 2miles - 1 mile
time = 0.1 hour
velocity on way to gas = ( 2 - 1 ) / 0.1
= 1 / 0.1 = 10 miles/hour

What kind of molecules were formed by abiotic synthesis? How did they form?
Answer: Abiotic processes synthesized small organic molecules, such as amino acids and nucleotides. These monomers were joined into polymers, including proteins and nucleic acids. Polymers were packaged into “protobionts,” droplets with membranes that maintained an internal chemistry distinct from their surroundings.
