Answer:
The surface area/volume ratio will decrease
Explanation:
How does this impose a limit on cell size?
Because the ability of a cell to exchange substances with its environment is proportional to its surface area.
Hence, if surface area/volume decrease and get too small, surface area is not sufficient to take up substances needed to support metabolism or get rid of wastes.

_________ is required for energy given to proteins in the phospholipid layer.
a.Anaerobic
b.Aerobic
c.Active transport
d.Turgor
e. Passive transport
Answer:
A
Explanation:
Active transport is required for energy given to proteins in the phospholipid layer (Option c).
Active transport is a type of transport across a cell membrane that requires energy, usually in the form of ATP, to move substances (either molecules or ions) against a gradient of concentration.
Conversely, passive transport refers to the movement of substances across a membrane in favor of a concentration gradient, which does not require energy.
Active transport is mediated by transporter proteins known as carriers and/or pumps.
In conclusion, active transport is required for energy given to proteins in the phospholipid layer (Option c).

- Which pair of features is correct for both a human liver cell and an Escherichia coli bacteria cell?
Answer:
contains DNA associated with protein, contains naked DNA
Explanation:
E coli are prokaryotes with naked DNA found in the cytoplasm. In contrast, human liver cells contain DNA present in a nucleus, a membrane-enclosed organelle. The DNA is associated with proteins (forming a structure called chromatin).
Human liver cells contain mitochondria, but E Coli do not contain membrane-bound organelles.
Eukaryotic ribosomes are larger than prokaryotic ribosomes. Eukaryotic ribosomes are 80S in size, prokaryotic are 70S in size.

Your answer:
Answer:
Captive breeding program
Explanation:
A captive breeding program can be defined as the process of collecting wild specimen and allowing them to reproduce in an environment away from predation. This is an important part of saving endangered species. Specimens of such species are bred in zoos and similar facilities in order to build a healthy population. Sometimes, these species are successfully reintroduced back into the wild. Examples of animals that were successfully saved like this are the California condor, black-footed ferret, golden lion tamarin, and red wolf.
2. How are the atmosphere, hydrosphere, and lithosphere related in the biosphere?
Answer:
These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.

Indicate whether a solution will have more OH– or H+ if the pH value of the solution
is 10.
The solution with a pH value of 10 will have more OH- ions.
In chemistry, pH is described as a scale that is specifically utilized to specify the basicity or acidity of an aqueous solution. The pH of different solutions are described as follows:
Acidic solution: If a solution has pH<7, then the solution is acidic and tend to have more H+ ions than OH- ions Neutral solution: The solution is neutral when pH=7 and the concentration of H+ and OH- ions are the same Basic solution: If a solution has pH>7, then the solution is Basic and tend to have more OH- ions than H+ ionsThus, in this case, pH>7 and thus we can conclude that the solution will have more OH- ions than H+ ions.

Why is meiosis important in maintaining genetic diversity?
Question 6 options:
A Meiosis creates diversity by cutting each chromosome exactly in half.
B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.
D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.
Answer:
We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Explanation:
Brainliest please?
Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.
Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
Other options-
A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.
C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.
D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

What is the answer to this please help
Answer:
C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.
Explanation:
Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription. Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme. Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.
If 35% of the bases in a region of the mouse genome are cytosine, what percentage in that region are adenine?
A. 15%
B. 20%
C. 30%
D. 35%
E. 40%
Answer:
A. 15%
Explanation:
DNA is composed of four nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Chargaff's rule of base pairing states that A always pairs with T, while G always pairs with C. The total distributed percentage of the four 4 nitrogen bases must be equal to 100%. In this case, the C content is 35%, thereby G=35% (i.e., equal to C content), while the remaining 30% must be equally divided between T=15% and A=15%.

How can competition contribute to evolution through natural selection?
Answer: During competition, organisms that have favorable traits for this task will survive and are said to be selected. These organisms will reproduce and pass on those traits to their offspring. Thus, the frequency of organisms with those traits will increase
Explanation: In Darwin's theory on the mechanism of evolution, competition among living things is viewed as a major part of the “struggle for existence” and therefore as a basis for natural selection (Darwin 1872).

Is the following sentence true or false? The apparent change in the
frequency and wavelength of a wave as it moves toward or away from an
observed is know as the Doppler effect.
True or False
Answer:
True
Explanation:
Doppler's effect is the apparent change in the wavelength and frequency of a wave as it moves towards or away from an observer.
The relative motion between the observer and the source causes changes to the wavelength and frequency. This effect is the doppler's effect. When a source moves closer, the frequency of the wave increases. For example, we see that effect of water ripples when a stone is dropped in still water.3.The two phases of photosynthesis are _____ reactions and _____ reactions._____. DOC 1

which sensory receptors are involved in hearing
Answer:
The cochlea is filled with two fluids (endolymph and perilymph), and inside the cochlea is the sensory receptor, the Organ of Corti, which contains hair cells, or the nerve receptors for hearing.
Have a good day
Mechanoreceptors are involved in hearing, which transmits the signals from external stimuli through mechanical ion-gated channels.
What is the structure of the ear?The organ of the Corti on the basilar membrane has hair cells that are involved in the sensory mechanism for hearing.
In the inner ear, there are six receptors (cochlea, two otolith organs, and three semicircular canals) which make a transduction unit consisting of hair cells.
In these receptors, external stimuli transmit the signal through the mechanically gated channel, external stimuli are touch, pressure, and hearing.
This processed signal to the brain by the neurons to hear the sound, and all the signal accumulate through the primary sensory receptors which are hair cells in the ear.
Therefore, mechanoreceptors are involved in hearing.
