why do dna strands copy different

Answers

Answer 1

Answer:

Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.

Explain how Enzyme A acts as a catalyst in the reaction. Be sure to include energy and time in your answer.

Answers

Answer:

Enzyme A acts as a catalyst by lowering the activation energy the reaction needs in order to take place this would in turn lower the reaction time of the reaction lading to a faster reaction. when conditions around the enzyme change this may lead to the breaking of hydrogen bonds causing the active site to change in shape, this change would would lead to the substrate no longer being able to fit which would lower the rate of reaction.

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?​

Answers

Atleast 3 Heads in 10 Coin Tosses
0.95 is the probability of getting 3 Heads in 10 tosses.
Answer:   1/2

In decimal form this is 0.5 and it converts to 50%

===================================================

Explanation:

Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%

This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.

Were you able to identify a cell undergoing cytokinesis in an onion cell? Explain.

Answers

Answer:

Mitosis and meiosis are different types of cell division, and although they are first ... One could be forgiven for the assumption that the classic 'onion root tip squash' ... magnification using the eyepiece and objective lens, you will need to be able to ... about how the cells were being used, and had been given no explanation, ...

Explanation:

The cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

Mitosis is a type of somatic cell division that has four main steps (prophase, metaphase, telophase and anaphase) followed by cytokinesis.

Moreover, cytokinesis is the division of the cytoplasm to form two daughter cells.

The cell plate is a transient compartment that grows between daughter cells. Once cytokinesis is completed, the cell plate gives rise to the cell wall.

In conclusion, the cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

What is the name of a specific type of model that shows how animals diverge during evolution?(1 point)

taxonomy

diagram

cladogram

Answers

Answer:

Cladogram.

Explanation:

A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.

I also chose taxonomy on the test and it was wrong. The right answer said cladogram.

A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.

What do you mean by Evolution?

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.

A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.

Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

The growth of plants stop if its apical part is cut,why?​

Answers

Answer:

On some kinds of plants, the meristem is arranged so that when the tip of a branch or stem - which contains the apical meristem, from which new growth is initiated - is cut off, new stems or branches are signaled to start growing from the side, an area called the cambium or lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new branches.

Explanation:

good luck

Answer:

The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down the stem towards the axillary bud... When the apical is removed bud I'd removed, the lowered IAA concentration allow the lateral buds to grow and produce new shoots, which compete to become the lead growth

A student crested a model to show the flow of energy in a terrestrial ecosystem.

Which of the following correctly describes the way energy enters and leaves the ecosystem?

A Energy enters the ecosystem as sunlight, which is used by plants to produce sugars Energy leaves the ecosystem as heat from plants, herbivores, carnivores, and decomposers
B Energy enters the ecosystem from decomposers and is used by plants to produce sugars Energy leaves the ecosystem during cellular respiration
C Energy enters the ecosystem when it is transferred from the herbivores to the plants. Energy leaves the ecosystem as heat from plants, herbivores, carnivores and decomposers
D Energy enters the ecosystem as sunlight, which is used by plants to produce sugars. Energy leaves the ecosystem as mineral nutrients​

Answers

The flow of energy in the terrestrial ecosystem is initiated by the sun and its flows to plants and then animal life and finally reaches the decomposers. Thus the option A is correct.

What is an ecosystem?

An ecosystem is an ecological unit and its function is to balance the flow of energy in the environment. The flow of energy is unidirectional and as energy flow in one direction, it cannot be destroyed completely as it changes its form.

The energy that is received from the sun is transferred to the green plants, they include this energy to animals that are producers to consumers that include primary consumers and secondary consumers to decomposers, and then this energy leaves the system.
