Which organelle is most likely to be found in both Archaea and Bacteria and why? (2 points)
Both require chloroplasts for photosynthesis.
Both have mitochondria to provide energy for the cell.
Both need a nucleus in which to store their DNA.
Both use ribosomes to synthesize proteins.
Answer:
The organelles that are most likely to be found in Archaea and Bacteria are ribosomes, which they use to synthesize proteins.
Explanation:
Both Archaea and bacteria are unicellular prokaryotic organisms, which have in common lack of nucleus and most of the organelles, however they have ribosomes that allow them to perform protein synthesis.
The differences between Archaea and bacteria have allowed taxonomic classification in different domains.
The other options are not correct because:
Although some bacteria and archaea can photosynthesize, it is not common to find chloroplasts in these organisms. Archaea and bacteria lack mitochondria. Prokaryotic organisms such as Archaea and bacteria do not have a nucleus, and their genetic material is dispersed in the cytoplasm.Answer:
Both use ribosomes to synthesize protien.

What causes uncontrolled cell division at the genetic level?
Answer:
mutations affecting proteins that normally regulate the cell cycle.
Explanation:
The function of the cell cycle is the duplication of DNA molecules in chromosomes and precisely separated by copying into two genetically identical daughter cells.
A tumor is an abnormal mass of tissue that results from the uncontrolled growth of cells.
Animals that live on intertidal rocks often exhibit compressed or dorsally flattened bodies. this is an adadptation that protects against:______
a. sunlight
b. high temperatures
c. desiccation
d. wave shock
e. predation
Answer:
d. wave shock
Explanation:
An adaptation can be defined as a phenotypic trait that makes an organism and/or species better suited to its environment, thereby this organism/species will have more chances to survive and reproduce in such conditions. Rock-dwelling aquatic animals have different ecological, morphological and behavioral adaptations to survive in this type of environment. In this regard, it is well-known that these organisms show dorsally flattened bodies, since it is one fundamental morphological adaptation which helps them to dissipate the force of the waves.

C. Electrons flow from an outlet into a toaster, causing it to heat a

D. A person rubs a shoe on a rug, causing extra electrons to be
transferred to the shoe.
Answer:
The correct example of current electricity is C. Electrons flow from an outlet into a toaster, causing it to heat a slice of bread.
Explanation:
Current electricity refers to the flux of charged particles through a conductor material per unit of time. In general, when we refer to electric current we are talking about the electron flux. Electric energy originates from the difference of electrical potential between two points when they get in contact through a conductor. This contact provokes an electrical current that consists of the transmission of negative charges called electrons through conductor materials such as metals from the source of generation to the point of consumption.
In the exposed example, the source of electrons is the outlet, while the point of electron consumption is the toaster. In this last artifact, electrical energy is transformed into heat to toast the bread.

How dose the process of photosynthesis create food
Answer:
Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.
Explanation:
The investigations conducted by Edwin Chargaff support the idea that DNA is the source of heritable information, and they also show a relationship between the ratios of the different nitrogenous bases in DNA. Based on the results of Chargaff's research, which is the best estimate of an organism's DNA base composition that contains 28.0% thymine
all the thymine pairs with adenine, therefore there is the same number of adenine and thymine bases and the same percentage
so we have 28%thymine and 28% adenine
100-28-28=44% left
this 44% is guanine and cytosine. All of the guanine pairs with cytosine and all of the cytosine pairs with guanine so we have 44/2=22% cytosine and guanine
composition:
28%adenine
28%thymine
22%guanine
22%cytosine

4. Discuss the sense organs of cnidarians
Answer:
To tell the truth I don't know what none of this stuff so I searched it up.
Explanation:
Cnidarian sense organs are thought to be exclusive to the medusa, a point we dispute subsequently. Nevertheless, the sense organs of the medusa are highly developed and distributed across Scyphozoa, Hydrozoa, and Cubazoa. In those hydrozoans with a medusa stage, many have eyes associated with the tentacle base.
Hope that is what you are looking for.
Answer:
he rhopalium, the sense organ bearing structure of Scyphozoa, as well as the Cubozoa (a modified group within the scyphozoans), contains the statocyst and eyes. It is borne on the margin of the bell in the medusa. The rhopalia of cubozoan medusae contain eyes with lenses, the most dramatic of cnidarian sense organs.

E. coli strain B is doubly infected with two rII mutants of phage T4. 0.2 ml of a 108 dilution of the progeny is plated on E. coli B and 0.1 ml of a 104 dilution of the progeny is plated on E. coli K. 16 plaques appeared on strain B, 400 on strain K. Calculate the recombination frequency between these two mutations.
To Find :
The recombination frequency between these two mutations.
Solution :
Formula of calculating recombination frequency is :
[tex]R.F = \text{Number of mutations}\times \dfrac{\text{number of k plaques} \times D.F }{\text{Volume used}}\times \dfrac{Volume'}{\text{Number of B plaques} \times D.F' }}[/tex]
Putting all given values in above equation, we get :
[tex]R.F = \dfrac{2\times 400\times 0.2 \times 10^4}{16\times 0.1\times 10^8}\\\\R.F = 0.01[/tex]
Therefore, the recombination frequency between these two mutations is 0.01 or 1 %.
Given:
No. of mutation = 2Volume, [tex]V = 0.1[/tex][tex]V'= 0.2[/tex]
k plaques = 400The formula:
→ [tex]R.F = No. \ of \ mutations\times \frac{No. \ of \ k \ plaques\times D.F }{Volume}\times \frac{Volume'}{No. \ of \ B \ plaques\times D.F'}[/tex]
By putting the values in the above formula, we get
→ [tex]= \frac{2\times 400\times 0.2\times 10^4}{16\times 0.1\times 10^8}[/tex]
→ [tex]= \frac{160\times 10^4}{1.6\times 10^8}[/tex]
→ [tex]= 0.01[/tex]

In humans, freckles (F), widow’s peak (W) and attached earlobes (E) are all unlinked dominant traits. A man with freckles, widow's peak and attached earlobes marries a woman with freckles, straight hairline, and attached earlobes. Their first child has no-freckles, straight hairline, and detached earlobes. What is the probability that their second child has no-freckles, straight hairline, and attached earlobes? Select one:
Answer:
The correct answer is - 3/32.
Explanation:
We know that freckles F is dominant over no freckles f, similarly, Widow's peak W is dominant over straight hairline w and attached earlobes are dominant over free earlobes.
So, the combination of alleles for each phenotype would be:
No freckles = ff , Freckles = FF, Ff
Free earlobes = ee , Attached earlobes = EE, Ee
Straight hairline = ww , Widow's peak = WW, Ww
In the question, it is given that the first child has no-freckles, straight hairline, and detached earlobes that would be - ffwwee genotype and as it is given that all alleles are in recessive which means both parents must have recessive alleles.
So, the correct genotype of the man will be FfWwEe and the woman will be FfwwEe.
(man = freckles, widow's peak, and attached earlobes (F_W_E_) and woman = freckles, straight hairline, and attached earlobes (F_w_E_))
then cross between: FfWwEe × FfwwEe
The probability of the freckles and no freckles would be-
Ff × Ff = 3/4 freckles, 1/4 no freckles
The probability of the widows and straight hairline would be-
Ww × ww = 1/2 widows peak, 1/2 straight hairline
The probability of the free earlobes and attached earlobes would be-
Ee × Ee = 3/4 attached, 1/4 free earlobes
Combined possibility of all three phenotypes: no freckles, straight, attached would be = 1/4 × 1/2 × 3/4 = 3/32
Thus, the correct answer is - 3/32.
explain two characteristics of arthropods that makes them most successful of vertebrates
Answer:
1. Exoskeleton
2. Jointed appendages
Please find the explanation of the mentioned characteristics below
Explanation:
Arthropods are a group of animals that lack backbones i.e invertebrates but possess jointed legs. Arthropods as their name implies all belong to a large phylum called ARTHROPODA. They include insects, crustaceans etc. Due to their large number among other animal species, their outstanding variety etc, they are considered the MOST SUCCESSFUL animals.
This success of arthropods can be attributed to the characteristics they possess. Two of them are:
- EXOSKELETON: The outside skeleton possessed by members of these phylum supports their body, movement and general protection.
- JOINTED LEGS/APPENDAGES: Arthropods are virtually the only set of organisms that have jointed appendages giving them the adaptational ability to live and thrive in almost every habitat, if not all.

The chromosome number produced in daughter cells as a result of mitosis is the 2n that is in option B, as in this process, the parent cell and the daughter cell contain the same genetic content.
What is the significance of a set of chromosomes?There are different sets of chromosomes in different species such as wheat's genetic contents differ from those of humans because humans have two sets (2n) of chromosomes, whereas some plants have tetraploid sets of chromosomes. The number of chromosomes remains constant after cell division in mitosis, and the cell gets the exact same copy in mitosis, which is 2n in the case of the human, as humans have a 2n set.
Hence, the chromosome number produced in daughter cells as a result of mitosis is the 2n that is in option B, as in this process, the parent cell and the daughter cell contain the same genetic content.
