What is the typical configuration of chromosomes in eukaryotic cells?​

Answers

Eukaryotes typically possess multiple pairs of linear chromosomes, all of which are contained in the cellular nucleus, and these chromosomes have characteristic and changeable forms.

Which two structures engage to create a muscle contraction?.

Answers

Muscle contraction occurs when actin connects with myosin.

Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.

For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.

This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.

Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.

what is the importance of predation in an ecosystem​

Answers

Answer:

Without predatation, things wouldn't eat each other.

Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...

If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)

It's a food chain. A CHAIN. Each varible depends on each other.

And a food chain has a direct impact on the ecosystem.

For example:

No rabbits mean there is so many grass and carrots left behind

No wolves means there are too many rabbits

So that means

No wolves

Whatever eats the wolves wont be alive

Whatever eats THAT wouldn't be alive

evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.

Answers

Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.

Bacterial cells are vastly different from human or animal cells. Some of these differences include:

Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagella

and many others.

Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.

Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

Answer:

Brown eyes are a dominant trait.

Explanation:

Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.

Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.

what parts of a cell are most likely involved with inherited traits?

Answers

Chromosomes are most likely involved with inherited traits.

What are Chromosomes?

A chromosome is defined as the long DNA molecule which contains part or all of an organism's genetic material. Most chromosomes consist of very long thin DNA fibers coated with packaging proteins where the most important of these proteins in eukaryotic cells are histones.

These structures are found in the nucleus of cells which contain long pieces of DNA. DNA is the material that holds genes and is the building block of the human body.

Chromosomes also contain proteins which help the DNA stay in the proper shape.

Thus, Chromosomes are most likely involved with inherited traits.

Methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.

What is the importance of methylation in the cell?

Methylation has many functions, such as in gene expression, where it can turn genes on or off by altering the way that DNA is packaged, such as by tightening or loosening the gene so that enzymes can access it; in DNA stability, methylation can help protect the genome from damage by stabilizing the DNA structure; and in epigenetic regulation, where it plays an important role.

Hence, methylation is an example of epigenetics that is present in the third option, and this methylation helps in the expression of the gene or the repression of the gene product in the cell.

Some municipalities say the looming salary bump will stress their finances and they want Ottawa to step up.This summer, the federal government and the union representing RCMP members ratified an agreement to deliver a sizeable pay increase to nearly 20,000 members.Constables who account for more than half of all RCMP officers will see their maximum salary jump from $86,110 as of April 2016 to $106,576 next year.The deal also lays out retroactive pay increases going back to 2017. The RCMP last updated its wage scale in 2016 and for years Mounties' pay lagged behind that of other police services. According to the agreement, the rates of pay will change within 90 days of Aug. 6, when the collective agreement was signed. It's then up to the RCMP to make its "best effort" to implement the retroactive payable amounts within 270 days of signing.The Federation of Canadian Municipalities (FCM) says communities that pay the RCMP for policing services are growing alarmed over the agreement's cost."It's widespread coast to coast to coast and our municipalities are actually very concerned, very, very concerned," said FCM president Joanne Vanderheyden, also the mayor of the municipality of Strathroy-Caradoc in Ontario."This issue is absolutely urgent given the potential impacts on municipal finances."Municipalities with populations of less than 15,000 pay 70 per cent of the costs, while the federal government pays 30 per cent. Municipalities with more than 15,000 residents pay 90 per cent.Vanderheyden said that while negotiations on the collective agreement were happening behind closed doors, municipalities were advised by the federal government to set money aside to cover the anticipated pay hike."Well, the percentage was way too low," she said, adding the retroactive pay also came as a surprise to most mayors."We are absolutely not against collective bargaining. That's not it. It's when you're not at the table and the direct impact comes to you."Ottawa is asked to swallow retroactive costs The FCM has written a letter to the federal government asking it to absorb all retroactive costs associated with the collective agreement. Without federal help, Vanderheyden said, "municipalities will be forced to make incredibly difficult decisions because they're either going have to make cuts to their essential services or pass it along to the property tax, local residents. Because they can't go into arrears, they can't go to deficits."Peter Brown, mayor of Airdrie in Alberta, said that while he firmly supports paying RCMP officers more, he was surprised by the final price tag. He said his city, just north of Calgary, has budgeted and held money back over the past few years but still has only about half of what it needs to cover the added policing costs."The message from me is, recognize that we've all been hit. We're all suffering," he said, referring to the pandemic.Brown said the collective agreement's impact on Airdrie's budget is "probably in a $3.5 million to $4 million range. That's the equivalent [of] a five per cent tax increase."Codiac RCMP spending rises to $39M in proposed 2022 budgetMalcolm Brodie, mayor of Richmond, B.C., said his municipality estimates the retroactive pay lump sum will cost it something between $9 million and $11 million, plus the annual pay increase itself."What that means for us is to cover that the amount going forward on our budget, that's about a one-time 2.5 to 3.5 per cent tax increase," he said."We certainly have stayed with the RCMP for a good reason. We think that they've done a good job for our community. Having said that, you know, it's getting a whole lot more expensive."A spokesperson for the federal Department of Public Safety said the department has kept in touch with regions with RCMP contracts on a regular basis since 2018."Contracting jurisdictions were aware that the salary of RCMP officers had been frozen since 2016 and that the collective bargaining process began in 2020. With the new collective agreement for RCMP regular members and reservists, salaries are in line with other police services across Canada," said Tim Warmington."It is fair for regular members and reservists as well as reasonable for Canadian taxpayers."answer please!!
