5. How do viruses cause diseases ?
Answer:
They infect a host, reproduce themselves or replicate if it is a virus, spread from their host and infect other organisms . They also all have structural adaptations that make them successful at completing their life cycles, which enable them to cause further disease.
Explanation:
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 explains biodiversity?
Answer:
The right option is; B) the total variety of organisms on Earth
Explanation:
The absolute assortment of living beings on Earth clarifies biodiversity
Biodiversity is the assortment and inconstancy all things considered (various plants, river creatures, and microorganisms) from all sources (marine, earthbound, and other sea-going biological systems) on earth or inside a specific area. Biodiversity includes hereditary assorted variety, species decent variety, and biological system decent variety which all capacities together to frame the unpredictability of life on earth.
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.

Option C. Crust is destroyed. at a convergent boundary.
A convergent boundary (additionally known as an unfavorable boundary) is an area on the earth in which two or greater lithospheric plates collide. One plate finally slides underneath the alternative, a procedure referred to as subduction. The subduction quarter can be described by using an aircraft where many earthquakes occur, known as the Wadati–Benioff region.
Convergent boundaries are the collision of the Indian Plate with the Eurasian Plate, creating the Himalayas Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of tiers extending from the Alps in Europe to the Zagros Mountains in Iran.

Having free earlobes (F) is a dominant trait in humans, and having attached earlobes (f) is Recessive. A Father has the genotype ff, and the mother has the genotype Ff. What is the fathers phenotype?
Answer:Attached earlobes
Explanation: As the phenotype is a visible trait, and the father has ff (a recessive trait) he has the attached earlobes.
Father has an attached earlobe because the father has both the allele in recessive condition.
What is phenotype?Earlobe attachment is a recessive feature, parents will be heterozygous for the character since the offspring has connected earlobes whereas both parents have free earlobes.
In humans, hypertrichosis of the ear is a holandric (Y-linked) trait, and connected earlobes predominate over free earlobes. A man who had long hair on his pinna and connected earlobes married a lady who had free earlobes.
With genotype ff, the person with attached earlobes can only generate e alleles. The person who has free earlobes and is heterozygous has the genotype Ff and is capable of producing both the Fand f alleles.
Therefore due to the recessive condition father shows an attached lobe phenotype.

Male tungara frogs make a loud distinctive call at night to attract mates. The nocturnal fringe-lipped bat, which preys on this species of frog, detects these calls. Which of the following statements most accurately describes how this
situation is an example of an adaptation that improves reproductive success for a species?
A. The frog has an adaptation to evade capture by one of its
predators, which helps ensure survival through its reproductive stage.
B. The bat has an adaptation that allows it to more easily locate prey, which helps ensure that it has energy needed for reproduction.
C. The frog has an adaptation that increases its ability to survive until it can mate and produce offspring.
D. The bat has an adaptation that allows it to cooperate with the frog so that the bat is better able to survive as a nocturnal species.
Answer:
B
Explanation:
Because the frog's call can attract the bat, they don't often live long enough to find a mate with said call. However, making a meal of the frog provides the bat with energy to help it with it's reproduction.

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.

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.
