A structure that looks the same and does the same job but was not present in a common ancestor is termed:______.

Answers

Answer 1

Answer:

The correct answer is - analogous.

Explanation:

Analogous structures or organs are the structures with the same look which is developed to perform the same job and not present because inherited by a common ancestor.

These structures are present in unrelated organisms and look the same from outside and perform the same action for example wings of bat and birds look and perform the same action but not inherited from a common ancestor.

Answers

Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).

Explanation:

A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.

According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.

The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

High tide is occurring on the sides of the Earth that are_______.

A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.

Answers

I think it’s C I’m not really sure

High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.

What is high tide?

When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.

The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.

On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.

The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.

High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.

Thus, the correct option is D.

what is accuracy, precision, and reproducibility ? and why are they so necessary in conducting/designing experiments

Answers

Answer:

- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.

- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.

- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.

Explanation:

In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

Primary succession occurs in an area that is disrupted by a

fire or other natural disaster but secondary succession does

not.

Primary succession occurs after secondary succession.

Primary succession involves only plants but secondary

succession involves animals too.

Primary succession occurs in an area with no life and no soil

but secondary succession happens in an area where an

existing community was disrupted.

Answers

Answer:

Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.

Explanation:

Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.

- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.

- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.

What were the ancestors of mitochondria according to the endosymbiotic theory?

B. Aerobic bacteria

C. Anaerobic bacteria

D. Chloroplasts

Answers

Answer:

d is your answer

Explanation:

Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.

What is endosymbiotic theory ?

According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.

Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.

Therefore, aerobic bacteria are the ancestors of mitochondria.

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.


What is the independent variable in this experiment?

Answers

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

Answers

Answer:

Please find the flowchart attached as an image

Explanation:

DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.

PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.
