1. They don't create too much pollution, which makes them "clean."
It allows us to have a clean air because there's no need of burning them just like the fossil fuels (non-renewable).2. They don't cost too much to run.
The supply of these resources doesn't cost anything at all. For example, solar energy relies on the heat of the sun. The sun's heat is definitely free and can be found in most sunny places.Negative
1. Setting up is expensive.
An example of this is the "wind turbine" that costs millions of dollars in order to set up.2. The output is affected by many factors.
Depending on the kind of renewable resource, most of these are affected by many factors. For example, wind turbines rely on wind's blowing while the hydroelectric powers can be affected by drought.es and Moion Assessment (Luncn)

Which statement did Virchow's work add to the cell theory?
A. Cells contain genetic material that consists of DNA.
O B. The cell is the basic structural and functional unit of life.
O C. All living things are made of one or more cells.
O D. All cells come from other living cells.
Answer:
D
Explanation:
The German doctor Rudolf Virchow proposed that all cells result from the division of previously existing cells, and this idea became a key piece of modern cell theory.
This results from cytokinesis when he observes cells splitting into two.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

Which of the following does not describe hormones in the body? I’ll mark the correct answer a brainliest
A. they are mediator molecules released in one part of the body but regulating the activity of cells in other parts of the body
B. most hormones enter interstitial fluid and then the bloodstream
C. hormones acts on muscles and glands only
D. hormones exert their effects by binding to receptors on or in the "target" cells
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
A particular triplet of bases in the coding strand of DNA is 5'-CGT-3! Which of
the following is the anticodon component of the tRNA that binds the mRNA
codon transcribed from this DNA?
AdGu 5
B. 3! - UGC-5
3 KGO15
0.3 AG 5
Answer:
The options to this question are incorrect.
The answer is 5'- CGU- 3'
Explanation:
DNA is the genetic material of living organisms that contains information on how to produce proteins needed for the normal functioning of the cell. This information is encoded in the nucleotide bases contained in the DNA molecule. The information is expressed via the process of transcription and translation.
Transcription is the process whereby DNA is used to synthesize a mRNA molecule. In this case, a particular triplet of bases in the coding strand of DNA is 5'-CGT-3. This undergoes transcription to give 3'- GCA- 5'.
This further undergoes translation with the aid of a tRNA, which carries the following anticodon component which is complementary to the mRNA codon: 5'- CGU- 3'.

Answer: The FDA and USDA cerate food safety programs, safeguards to protect Americans, to protect people from unsafe food. The FDA has monitoring programs for pathogens, naturaltoxins, pesticides, etc.; their methods are science-based.
The safeguards that are placed to protect Americans from unsafe food are FDA and USDA. FDA means food and drug administrator and USDA means U.S. department of agriculture.
What are FDA and USDA?FDA stands for food and drug administrator. It is a health and food department to ensure public health and to check the food items that the citizens are consuming.
USDA stands for The United States Department of Agriculture. The department is responsible for making the laws regarding food quality, and they also develop new qualities of fruits and vegetables.
These departments are based on scientific research and methods. Many scientists work under this to save people from having bad food.
Thus, The FDA and USDA are the safeguards set up to protect Americans from tainted food.

2. The researchers in the film spent a month collecting and identifying various species of animals and plants. These species were then added to a database of all species in Gorongosa. Provide two (2) reasons why building a species database will be useful for the restoration project.
Answer:
Importance of building specie database, for restoration projects.
Explanation:
Restoration implies human intervention, for renewing - degraded ecosystems & habitats.
Building species data base is important for this, as - wildlife is an integral part of habitat. Understanding their favourable living ambience in ecosystem - like temperature, humidity, sunlight & water access and migration patterns is important - in effort to restore environment in real sense.
Determine which of the following choices is the best match for the questions that follow: A. Whole-organism Vaccine B. Subunit Vaccine C. Toxoid Vaccine D. Experimental Vaccine
Answer:
Experimental Vaccine Herpes Vaccine = D
Attenuated = B
Purified macromolecule Vaccine = B
Recombinant-Vector Vaccine = A
Inactivated or Killed = C
Diphtheria Vaccine = A
Explanation:
A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.
Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).
The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Can you please help me I am super stuck
Answer:
a.) 12 Newtons
b.) Same Direction
c.) Unbalanced
Explanation:
The system shows 2 individual forces:
A force of 5 N pulling the box LEFT
A force of 7N pushing the box LEFT
Both forces are LEFT, so they have the same direction.
Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:
Resultant force's magnitude is then: 5N + 7N = 12N
Resultant force's direction: unchanged = LEFT
Since the resultant force's magnitude is not 0, the system is unbalanced.

Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determine the phenotypes of the F1 generation resulting from a cross between a heterozygous long legged, weak muscled horse and a heterozygous long legged, strong horse
Answer:
See the answer below
Explanation:
Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).
Heterozygous long leg, weak muscle = Llgg
Heterozygous long leg, strong muscle = LlGg
Llgg x LlGg
Offspring:
2 LLGg - Long leg, strong muscle
4 LlGg - Long leg, strong muscle
2 LLgg - Long leg, weak muscle
4 Llgg - long leg, weak muscle
2 llGg - short leg, strong muscle
2 llgg - short leg, weak muscle
Ratio of offspring with long leg and strong muscle = 6/16 or 3/8
Ratio of offspring with long leg and weak muscle = 6/16 or 3/8
Ratio of offspring with short leg and strong muscle = 2/16 or 1/8
Ratio of offspring with short leg and weak muscle = 2/16 or 1/8
