Answer:
homologous
Explanation:
Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.
The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
The data type that contains recorded measurements is called
Answer:
The data type that contains recorded measurements is called [X] data. Quantitative.
Explanation:
Answer:
Quantitative Data
Explanation:
Qualitative measurement focuses on collecting information that is not numerical. You can remember this by thinking of the word 'quality. ' Quality is not something that you measure with numbers. You don't say that dinner was 3 qualities, or that park bench is only 1 quality.
Quantitative data is data expressing a certain quantity, amount or range. Usually, there are measurement units associated with the data, e.g. metres, in the case of the height of a person. It makes sense to set boundary limits to such data, and it is also meaningful to apply arithmetic operations to the data.

Event 1
Event 2
Which event is most likely an example of a chemical reaction?
Event 1 because there is a color change.
Event 1 because there is a release of heat and light.
Event 2 because the temperature is dropping in the liquid.
Event 2 because the blue color mixes throughout the liquid.
Answer:
Event 1
Explanation:
Event in which there is color change is most likely to be an example of chemical reaction as there is chemical change taking place in it.
What are chemical changes?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

8 What does the sample space represent?
Answer:
In probability theory, the sample space (also called sample description space[1] or possibility space[2]) of an experiment or random trial is the set of all possible outcomes or results of that experiment.[3] A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S, Ω, or U (for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.[4]
For example, if the experiment is tossing a coin, the sample space is typically the set {head, tail}, commonly written {H, T}.[5] For tossing two coins, the corresponding sample space would be {(head,head), (head,tail), (tail,head), (tail,tail)}, commonly written {HH, HT, TH, TT}.[6] If the sample space is unordered, it becomes {{head,head}, {head,tail}, {tail,tail}}.
For tossing a single six-sided die, the typical sample space is {1, 2, 3, 4, 5, 6} (in which the result of interest is the number of pips facing up).[7]
A subset of the sample space is an event, denoted by E. Referring to the experiment of tossing the coin, the possible events include E={H} and E={T}.[6]
A well-defined sample space is one of three basic elements in a probabilistic model (a probability space); the other two are a well-defined set of possible events (a sigma-algebra) and a probability assigned to each event (a probability measure function).
Another way to look as a sample space is visually. The sample space is typically represented by a rectangle, and the outcomes of the sample space denoted by points within the rectangle. The events are represented by ovals, and the points enclosed within the oval make up the event.[8]
how does the size of a hydrocarbon molecule affect the volatility of crude oil?
Answer:
Longer hydrocarbon molecules have a stronger intermolecular force. More energy is needed to move them apart so they have higher boiling points . This makes them less volatile and therefore less flammable .

Consider this animal cell. The organelles in an animal cell are labeled. Part D are stacked tubular structures. Which organelles are labeled D, and what is one feature that distinguishes them from the other labeled organelles? chloroplasts; the only organelles that produce sugars from sunlight ribosomes; only found in animal and bacterial cells centrioles; found in animal cells but not plant cells mitochondria; the only energy-generating structures found in cells
Answer:
The image of the animal cell was not included in the question, the image has been added as an attachment.
The answer is centrioles; found in animal cells but not plant cells
Explanation:
According to the question, the image in the attachment section is an animal cell with labelled organnelles. An animal cell does not possess a Chloroplast, which is unique to only plant cells. Hence, organnelles D cannot be Chloroplast.
Ribosomes are organnelles made up of a complex of RNA and proteins. They are the site of protein synthesis, which occurs in all living cells. Hence, all cells including plant and animal cells contain Ribosome organnelles. Therefore, it is a wrong choice.
Centrioles are cylindrical tube-like structures made up of microtubules arranged in a specific pattern. Centrioles are present only in animal cells and play a major part in cell division, where they organize microtubules that separate chromosomes. As seen in the image, the two centrioles are perpendicular to one another, forming a CENTROSOME. A plant cell does not possess centrioles instead they contain microtubules organizing centres (MTOC).
Mitochondrion are present in both animal and plant cells as energy-generating organnelles but they are not stacked tubular structures as described in the question.

Which of the following situations would be followed by primary succession? (Choose all that apply) severe landslides overgrazing lava flows earthquake
Answer: lava flows, earthquakes
Explanation:
The primary succession begins in an area, where no life sustains initially. Such regions have no soil thus incapable of sustaining life. The land is considered primitive or underdeveloped.
The lava flow, retreating glaciers, sand dunes, earthquakes are the factors which are responsible for primary succession.
The lava will flow over a surface and will solidify into rocks. The rocks undergo withering. The earthquakes are responsible for disturbing the land.
earthquake, lava flows, severe landslides
Primary succession begins on a bare area, such as rock, without vegetation or soil.

When a single cell of E. coli reproduces, it first duplicates its DNA. Next, the cell elongates as each copy of DNA is pulled toward opposite ends of the cell. The membrane then pinches inward, dividing the cytoplasm into two halves and producing two daughter cells. What is true about these daughter cells?
The options are:
A. They are genetically different from the parent because they are produced by sexual reproduction.
B. They are genetically identical to the parent because they are produced by sexual reproduction.
C. They are genetically identical to the parent because they are produced by asexual reproduction.
D. They are genetically different from the parent because they are produced by asexual reproduction.
Answer:
The correct answer is- C. They are genetically identical to the parent because they are produced by asexual reproduction.
Explanation:
E. coli reproduces through binary fission in which the genetic material of cell of E. coli first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.
After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other E.coli therefore the resultant daughter cells are identical to the parent cell.
Therefore the correct answer is option c.
Answer:
They are genetically identical to the parent because they are produced by asexual reproduction.

Which organelle makes proteins that are needed by the cell
Answer:
ribosomes
Explanation:
Ribosomes can be described as large biomolecular complexes that are composed of RNA (particularly ribosomal RNA) and proteins.
They act as site for the synthesis of protien in both prokaryotes as well as eukaryotes.
mRNA (messenger RNA) arrives at ribosome after it gets transcribed from DNA.
mRNA gets converted to particular protein (through assembly of amino acids that are carried by specific tRNA molecules according to codons in the mRNA) that is needed by the cell.
This process is known as translation and it takes place at the site called ribosome.

If 15% of a DNA double helix is the base adenine what are the percentages for the following bases?
Thymine _____
Guanine _____
Cytosine _____
Answer:
Thymine 15%
Guanine 30%
Cytosine 30%
Explanation:
Remember Chargaff's rules: C=G, T=A.
A = T
.15 = T
Now we've got .30 A and T, so we know 1 - .3 = .7 of the DNA should be guanine and cytosine.
.7 / 2 = .35
.35 = G
.35 = C

What the walls of small intestine produces?
Answer:Mucous
Explanation:
Read the following claim.
The energy animals need to survive was once energy from the sun.
What evidence from the article supports this claim? Think about energy pyramids, then explain how the evidence from the article supports this claim.
Answer: The energy from the sun is the only source of energy which has the ability to sustain life on earth.
The energy pyramid states that the transfer of energy is unidirectional and it flows from the producers to the consumers.
There are different trophic levels at which the organism are found say herbivores, carnivores and top predators.
All of the organism are dependent on the producers for their source of energy.
hence, the sunlight helps autotrophs to make food and herbivores feed on them and then the carnivores animals feed on herbivores and then the top predators feed on the carnivores animals.
So, ultimate source of energy on earth is sun, which directly or indirectly provides energy to the producers and other animals.
