is an example of a(n)
O A. keystone species
O B. extinct species
O c. invasive species
O D. introduced species
Answers
Answer:
C
Explanation:
Invasive species are usually species that enter an environment and cause destruction to the food chain, biodiversity, and the overall way of life. The toad outcompeteing the frogs that are supposed to be in the environment suggest it's an invasive species.
An introduced species would be if the toad was purposely introduced to the environment, which it was not.

FOG is prepared during the process of cooking and the washing up processes. When FOG is allowed n sewer pipes it can accumulates inside sewer pipes, so proper disposal method of FOG is required.
Some of the source of FOG and disposal methods are as following:
Cooking oil - Allow the oil to be cooled and place it in a non-recyclable container such as plastic-lined paper containers.
Food Scraps: compost bin can be used to dispose FOG by putting all food scrap into it.
Salad dressing - If little maount of salad dressing is left, use a paper towel to clean it and it will absorb the left residue which can be easily dipose in garbage.
Dairy products such as milk - it can be disposed on-farm or to a proper disposal site otherwise it will affect groundsurface as it contain fat.
Hence, using above methods for disposing FOG will help to save envrionment.

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits. A flow chart is shown. A and B both go to C. C goes to both D and E.
Answers
Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “Green pods” appear?
1.A and D 2.B and E 3.A,C and D 4.A,B,C,D and E
Answer:
3.A,C and D
Explanation:
As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.
As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand read
Answers
Answer:
TAGCCAGTTCGATCC
Explanation:
In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).
If we have the strand:
ATCGGTCAAGCTAGG
We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:
TAGCCAGTTCGATCC

A medical test indicates that a patient has a defective protein. This
condition is most likely due to a change in the directions coded in the:
number of phosphate molecules
sequence of subunits in DNA
number of nitrogen bases
sequence of sugar molecules
Answers
Answer:
number of nitrogen bases
Explanation:
The correct answer would be the number of nitrogen bases.
A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.
Mutation can occur in a variety of ways including:
1. Deletion of nucleotide base sequence in the DNA
2. Addition (insertion) of nucleotide base sequence in the DNA
3. Duplication of nucleotide sequence in the DNA
A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.
Hence, the correct option is number of nitrogen bases.

Your answer
In a stable population of rabbits and wolves a government agency enacts a 1 point
Answers
Answer:
1.33 dandelions per square meters
Explanation:
The correct answer would be 1.33 dandelions per square meter of land.
Size of quadrat = 1.5 square meters
Average number of dandelions per quadrat = 2
Total study area = 4500 square meter
Population density = number of organisms per unit area
There were 2 dandelions per 1.5 square meters
How many would be per square meter?
= 2 x 1/1.5 = 1.3333 dandelion per square meters
To 2 decimal places = 1.33 per square meters

Why does light from the sun melt the plastic when light from the desk lamp does not
Answers
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Lamps are electrical devices that use electrical energy in the form of electrical current.

Explain the unique bonding properties of carbon.
Answers
Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.
What do you mean by valence electrons?A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.
