Give An Example Of How Cells Structure Relates To Its Functions In The Body

Answers

Answer 1
Structure dictates function. ... Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (rRNA). Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins
Answer 2

Answer:

The structure of the cellular components in a cell determines the function of component.

Take the case of an organelle which produces energy in a eukaryotic cell called mitochondria. Mitochondria are structured in a way that it can synthesize a large amount of ATP in a small enclosed area.  

The structure of mitochondria contains outer membrane, inner membrane and the matrix. The membranes are structured that they can hold and accumulate the protons and allow the flow of proton. Similarly, the inner membrane gets folded to increases the output of ATP synthesis by forming infoldings called cristae which embodies ATP synthase.

This shows how the structure and functions are related in a cell.

Differentiate between the lithosphere and Asthenosphere.

Answers


Difference between Lithosphere and Asthenosphere
• The difference between lithosphere and Asthenosphere pertain to their compositions.
• While lithosphere is hard and rigid, Asthenosphere is a layer made up of molten rocks.
• Lithosphere stretches from the top of the earth’s crust down to first 100 kilometers while Asthenosphere lies beneath lithosphere
• Rocks are under severe pressure in Asthenosphere, whereas they face much less pressure in lithosphere.
• The mineral composition of lithosphere is varied as it contains more than 80 minerals whereas Asthenosphere is mainly comprised of silicates of iron and magnesium.
• The depth of the lithosphere is about 100 kilometers, whereas the depth of Asthenosphere is 400-700 kilometers.

Final answer:

The Lithosphere consists of the Earth's crust and the uppermost part of the mantle. It contains the tectonic plates. The Asthenosphere sits beneath the lithosphere and is a semi-fluid layer where heat convection occurs, driving tectonic movement.

Explanation:

The Lithosphere and the Asthenosphere are two different layers of the Earth. The Lithosphere consists of the Earth's crust and the uppermost part of the mantle. It is broken up into tectonic plates; these plates are moving apart in some areas, like the Atlantic Ocean, and being forced together in others, such as off the western coast of South America. The Asthenosphere, on the other hand, is located directly below the lithosphere and is part of the upper mantle. It is regarded as the 'hot, weak layer' because of its physical state, which is plastic or semi-fluid. It is here that convection occurs, taking heat from the interior and transporting it to the upper mantle. This convection is the power source for the movement of the tectonic plates.

The nurse is asked to obtain a urine sample from a school-age child for a urine culture to detect bacteriuria. which intervention does the nurse implement?

Answers

Bacteriuria or Asymptomatic Bacteriuria (ABU) is not a common condition or children. If the nurse is asked to obtain a urine sample from a school-age child for a urine culture to detect bateriuria, the nurse should implement the following interventions:
1. The nurse should obtain an early morning sample of urine as it gives the accurate results.
The child should not be allowed to drink water before giving the sample as water dilutes the bacterial count of the urine and might give false report.
3. There are chances of contamination of the sample and the urine might change its characteristics in a given period of time. Thus, the urine sample should be brought immediately to the laboratory for urine culture.

Compounds that contain a fused ring system are called

Answers

The answer is Steroids
Final answer:

Polycyclic aromatic hydrocarbons (PAHs) are compounds with fused ring systems, while heterocyclic compounds have rings with non-carbon atoms like nitrogen.

Explanation:

Compounds that contain a fused ring system are known as polycyclic aromatic hydrocarbons (PAHs). These structures consist of multiple aromatic rings, such as benzene rings, that are joined together and share one or more sides or edges. For instance, the basic structure of steroid hormones includes a system of three six-membered rings and one five-membered ring that are connected in this way. These rings have bridgehead carbons that link them together. Furthermore, some cyclic compounds contain atoms other than carbon, called heterocyclic compounds. Notable examples are purine and pyrimidine, which are key components in nucleic acids and contain nitrogen atoms within their fused ring structures.

igneous rock can be changed into which type of rock through the application of heat and pressure?
A. Foliated igneous rock
B. Non-foliated igneous rocks
C. Clastic sedimentary rock
D. Metamorphic rock

Answers

Answer:

D. Metamorphic rock

Explanation:

i did test and got it 5/5

Igneous rock can be changed into metamorphic rocks by the application of heat and pressure. This changes the shape and size of rocks. Thus, the correct option is D.

What is Metamorphic rock?

Metamorphic rocks formation occurs when igneous rocks are subjected to very high temperature, pressure, and hot mineral-rich fluids. This leads to change in the shape and size of the rocks.

Metamorphism is a process which changes the pre-existing rocks into new forms because of the increase in temperature, pressure, and chemically active fluids. Metamorphism may affect different types of rocks like igneous, sedimentary, or other metamorphic rocks.

During this process, new minerals form, with different sizes, shapes, and orientations than those of the original ones. The chemical composition of the original rocks may also change, as elements are carried away and some are added by the fluids flowing to the rocks.

Therefore, the correct option is D.

During dna replication in a bacterium a g is mistakenly inserted into the newly-synthesized dna strand opposite a t in the template dna strand. if this mistake is not repaired before the next round of dna replication, what mutation will eventually result?

Answers

The type of mutation that will eventually occur is A TO G BASE SUBSTITUTION. 
In this type of mutation,  what will happen is that, in all the points where adenine base is suppose to be inserted, it is the guanine base that will be inserted there. This is an example of base substitution error in DNA replication.
Answer:

The mutation will be one base substitution mutation.

Explanation:In the newly forming strand only one G is inserted mistakenly.As we know DNA replication is a semi conservative model.In which two strands of double stranded DNA will be two separate templates for the two newly strands of DNA.As one of the strand has one wrong nucleotide in its sequence. As if it is not repaired the substitution will become the part of newly formed strand formed from this mutated strand.And this mutation will pass onto next generation with half correct DNA and half wrong DNA.

A trait is likely to be heritable if _____ are more similar in that trait than _____.
a. dizygotic twins; monozygotic twins
b. monozygotic twins; dizygotic twins
c. ordinary siblings; dizygotic twins
d. dizygotic twins; ordinary siblings

Answers

a. Dizygotic twins originate from two different eggs, whereas monozygotic twins come the same egg. Monozygotic twins are"identical" because they come from the same egg, and so similar traits between them do not indicate any hereditary tendencies. Dizygotic twins come from two different eggs. Because of this, similarity between them is more likely to be due to a hereditary tendency, because both eggs had to individually inherit the trait.

Crossing over occurs when

A- sister chromatids are pulled apart at the centromere during anaphase II

B- homologous chromosomes join together to form tetrads during prophase I

C- chromosomes are grouped together into new nuclei during telophase II

D- tetrads of homologous chromosomes randomly line up in metaphase I

Answers

Correct answer:
"B- homologous chromosomes join together to form tetrads during prophase I"

It is during prophase I that homologous chromosomes join together (synapsis) and form tetrads - four chromatids are together in the new structure of two chromosomes - and this is the reason why crossing-over occurs in this phase. It is in this tetrad that both arms of both chromosomes may crossover and matching regions exchange places. This process results in homologous chromosomes recombination leading to genetic variability. 

The correct answer is B: homologous chromosomes join together to form tetrads during prophase I

what type of consumer is a flagfish?

Answers

Answer:

algae

Explanation:

Final answer:

Flagfish, or dinoflagellates, are generally considered to be primary producers due to their ability to photosynthesize. However, some also consume other organisms, which could classify dinoflagellates as primary or secondary consumers. Some dinoflagellates are filter feeders, a type of consumer that strains food particles from the water.

Explanation:

A flagfish, also known as dinoflagellates, fall within the group of organisms called the Chromalveolata. The dinoflagellates are mostly marine organisms and are an important component of plankton. They possess various nutritional types which include being phototrophic, heterotrophic, or mixotrophic. Dinoflagellates use chlorophyll a, chlorophyll c₂, and other photosynthetic pigments which helps them to photosynthesize. Additionally, these organisms have two flagella, that help them move.

In the context of the food chain, dinoflagellates are primary producers. However, some can also consume other organisms, acting as primary or secondary consumers depending on their diet. Certain dinoflagellates are known to produce neurotoxins that can cause paralysis in other organisms, posing a threat when ingested.

An interesting example from the Opisthokonts, are the choanoflagellates. The single, apical flagellum in these protists is surrounded by a contractile collar composed of microvilli, which is used to filter and collect bacteria for ingestion by the protist. This classifies them as filter feeders, a type of consumer that strains food particles from the water.

Why are lichens a good pioneer species after a volcanic eruption?

Answers

The question is asking to choose among the following choices that states the reason why are lichens a good pioneer species after a volcanic eruption, and base on my research, They are able to grow on bare rock. I hope this would help.

Answer:

The pioneer species are defined as those species that are very strong and hardy and also they have the capability of enriching the soil particles that favor their growth and development.

The lichens are considered to be a good pioneer species because they have the ability to settle on the surface of the bare rocks, where they can produce acid that allows the rock to disintegrate and results in the generation of soil particles.

Thus, the lichens are a pioneer species that can evolve rapidly after an eruption of a volcano.
