just the number, round to the nearest 2 decimal places) *
Your answer
In a stable population of rabbits and wolves a government agency enacts a 1 point
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

Explanation:
If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand read
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

how does a tree develop its thick bark
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
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.

Explain the unique bonding properties of carbon.
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.

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.
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.

Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain
THXSSS PLEASE HELP AND HURRY
Answer:
Explanation:
Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.
When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.
Answer:
Sea breeze.
This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface
Explanation:
Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.
Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.
During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze

Answer:
FOG stands for 'fats, oils and grease'. It is present infood products such as lard, butter, animal fats, vegetable oils, and dairy products.
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.
