Which process(es) explain(s) how cells with the same genetic information can produce cells with unique structures and therefore functions? Select all that apply.
Answer:
cell mutations
Explanation:
The process(es) that explain how cells with identical genetic information can produce cells with distinct structures and functions are cell differentiation and gene expression, which influence the cell to produce different structures.
What is the significance of gene expression?Gene expression is the process by which the cells can express certain types of genes, and this is possible due to the presence of a certain promoter and enzymes that can access the gene. This makes multicellular animals have different cell types and different cell structures, such as the proteins that are formed in the nervous cell, which are different from the proteins of the skin cell.
Hence, the process(es) that explain how cells with identical genetic information can produce cells with distinct structures and functions are cell differentiation and gene expression, which influence the cell to produce different structures.

two models of sells are shown below. Why would model b be better for moving nutrients in and out of the cell?
Answer:
The correct answer is - C. It has a larger ratio of surface area to volume.
Explanation:
In cell B, the ratio of surface area to volume is larger in comparison to cell A. The surface area to volume ratio can be understood as it is the size of surface area that the volume of a particular substance can move in or out of the cell, in a unit of time.
Thus the larger the ratio of surface area to volume faster the diffusion rate of nutrients will be as the surface area is a square measurement and volume is cubed so the surface area increases faster than volume.

If having long fur helps a guinea pig survive, what
would you expect to see change in the population
as it evolves?
DONE
In a population with long fur, there will be more guinea pigs than short fur in the given scenario.
What is trait?A trait, as it relates to genetics, is a unique feature of an individual.
If having long fur helps a guinea pig survive, we can expect the long-furred trait to become more common in the population as it evolves.
This is because guinea pigs with long fur would have an advantage in colder environments, allowing them to retain body heat more effectively and survive longer.
As a result, longer-furred guinea pigs are more likely to survive and reproduce, passing on their long-furred trait to their offspring.
As this process continues over many generations, the proportion of guinea pigs with long fur in the population will increase, while the proportion with short fur will decrease.
Thus, this can be expected to see change in the population as it evolves.

Answer:
100% of the offspring would be black fur, black eyes (16/16)
Explanation:
(Because the info. wasn't included here, I'm assuming black fur and black eyes are dominant, BBEE, to the recessive white fur and red eyes, bbee)
For BBEE x bbee, you'd create a typical dihybrid true-breeding punnett square , where the first top row would be BE , BE, BE , BE , and the vertical/side row would be be, be, be, be.
Cross these alleles as you would typically for any punnett square, and you'd see that all the offpsring would result in BbEe genotypes, which is true of any true-breeding dominant x recessive cross, which always results in the dominant phenotype being 100%.
So...
Black Fur and Black Eyes : 16/16 (100%)
Black Fur and Red Eyes: 0/16
White Fur and Black Eyes: 0/16
White Fur and Red Eyes: 0/16

how does the force exerted on the same mass differ between short and long bones
Answer:
Muscles, bones, and joints are some of the most interesting applications of statics. There are some surprises. Muscles, for example, exert far greater forces than we might think. Figure 1 shows a forearm holding a book and a schematic diagram of an analogous lever system. The schematic is a good approximation for the forearm, which looks more complicated than it is, and we can get some insight into the way typical muscle systems function by analyzing it.
True or False: Purine is connected to pyrimidine using oxygen bonds.
Answer:
False
Explanation:
In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).
Which if the following is a biotic factor in a deciduous forest biome?
A Temperature
B Precipitation (rain)
C Soil
D Trees
Answer:
[tex]\boxed {\boxed {\sf D. \ Trees}}[/tex]
Explanation:
A biotic factor is a living part of an ecosystem. Animals, plants, fungi, and bacteria are all examples.
Let's examine the list we are given. We have temperature, precipitation (rain), soil, and trees.
Temperature, precipitation, and soil are not living. These are all abiotic factors. They are still part of the ecosystem, but they are not alive. So, that leaves trees, which are plants, as the biotic factor in a deciduous forest biome.

how changes in the atmosphere effect to the plants growth?
Answer:
Mark brainliest please!
Explanation:
Climate change affects the growth of plants in many ways but as we know its 3. The first, as CO2 levels increase, plants don't need a lot of water to do photosynthesis. Scientist have now discovered a third effect: As CO2 levels go up higher, it amps up photosynthesis. Plants in more of this heat, CO2-rich environment grow bigger and better, with more plant like leaves and such.

When a homozygous (purebred) black-furred (BB) male is crossed with a female that has the recessive white fur (bb). The resultant offspring will have Black-fur (Bb) in the F1 generation.
What is a Punnett square?Punnett square may be defined as a table in which all of the probable consequences for a genetic cross between two individuals with comprehended genotypes are presented.
The selfing of the F1 generation, i.e. Bb × Bb resulted in the genotypes of BB, Bb, Bb, and bb. The Phenotypes are Black-fur: white fur in the ratio of 3:1.
The Punnett square of the above cross is represented below:
The percentage of probable phenotype:
Black fur = 100%

Benjamin invests $400 in a savings account that earns 5% interest each year.
Which expression gives the balance in the account after 3 years?
Answer: $460
Explanation:
To solve the question, we need to calculate the interest generated firstly and this will be:
= Principal × Rate × Time
= $400 × 5% × 3
= $400 × 0.05 × 3
= $60
The balance in the account after 3 years will be:
= Principal + Interest
= $400 + $60

There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce allele b. What is the gene frequency of allele b in the population if the population of Pakicetus reaches 100,000
Answer: Hello your question is incomplete below is the complete question
Let’s look at a different gene locus, we’ll call it B. The normal, wild type, the population was 100% BB. There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce allele b. What is the gene frequency of allele b in the population if the population of Pakicetus reaches 100,000
answer : ≈ 1
Explanation:
Determine the Gene frequency of allele b
Population = 100,000
There are 150 Pakicetus in population i.e. 300 alleles at locus B
hence the frequency of b = 1/300 = 0.33%
Increase in population does not affect frequency of b ( HW equilibrium )
therefore the Gene frequency of allele b
= 0.33% * 0.33% * 100000 = 1.08
≈ 1
