Answer 1

Answer:

It does not contain chlorophyll which is needed to absorb light or energy.

Answer 2

Answer:

The parts without chlorophyll do not photosynthesise, and so they do not make starch and the iodine does not change colour.

The green parts contain chlorophyll and photosynthesise to make starch.

The white part of the leaf does not contain chlorophyll, so does not photosynthesise.

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

An important example of a "positive feedback loop" in the polar climate system is:

a.Scientists in remote places check on each others instruments.

b.Warming ocean water opens new areas for marine species.

c.Warmer winters cause more plant growth, providing more food.

d.Sea ice melt opens more ocean to sunlight, causing more melt.

Answers

Answer:  D

Explanation:

A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.

In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.

The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.

The following information related to the positive feedback loop is:

If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.

Therefore we can conclude that option d is correct.

All other options seem incorrect.

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.

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.

Option A is the right answer

a population of white moths lives in a forest near a factory. this factory burns coal and pollutes the air with black dust. over time, this dust has settled on the trees in the area, making them darker in color. this could result in
1. an increase in the white moth population.
2. a decrease in the white moth population
3. an increase in the number of trees in the area
4. a decrease in the air pollution affecting the area

Answers

The answer to your question is option b

This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease

Answers

Answer:

Explanation:

Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.
