The earliest hominins probably lived in which kind of environment?

Suppose a species of bird called the red-crested warbler has a plumage length that is controlled by a single gene. The Plm allel

We are going to have different allele frequencies for the two populations

North American:

72 birds total => 144 alleles

72 - 55 birds = 17 short plume birds.

q^2 = (2*17) / 114 = 0.236

Freq(short plume allele) = q = 0.486

Freq(long plume allele) = p = 1 - q = 0.514

From this North American population we get

0.486 * 114 = 55 long plume alleles

0.514 * 114 = 59 short plume alleles

South American:

252 birds total => 504 alleles

252 - 75 birds = 177 short plume birds.

q^2 = (2*177) / 504 = 0.702

Freq(short plume allele) = q = 0.838

Freq(long plume allele) = p = 1 - q = 0.162

From this South American population we get

0.162 * 504 = 82 long plume alleles

0.838 * 504 = 422 short plume alleles

Blended population has

55 + 82 = 137 long plume alleles

59 + 422 = 481 short plume alleles

137 + 481 = 618 total alleles

p = 137/618 = 0.222

q = 481/618 = 0.778

The new population has the p and q from the blended population. The new population has 1000 individuals. The portion of long plumed will be homozygote long plumage + heterozygote, which is p^2 + 2pq, and you multiply that by the population size 1000 to get the final answer.

population size * (p^2 + 2pq) = 1000 * (0.222^2 + 2*0.222*0.778) = 395 birds (answer)

a sponge 1cm in diameter and 10 cm tall can move 22.5 L of water through its body each day. what volume of water will it pump th

Marat540 [252]

The part of the question about the size of the sponge is just there to trick you; you don't need it. All you need is the 22.5 L per day.

To find the amount of water it can pump in 1 hour, you divide the 22.5 by 24 because there are 24 hours in a day:

$(\frac{22.5L}{day})(\frac{day}{24hours})=0.9375\ liters\ per\ hour$

Now that we have hours, we can divide that by 60 to get the amount pumped per minute (because there are 60 minutes in an hour):

$(\frac{0.9375L}{hour})(\frac{hour}{60minutes})=0.015625\ liters\ per\ minute$

Check all the characteristics below that describe<br> Compounds

MrRa [10]

Answer:

Two or more elements,

Two or more elements,Chemically combined elements,

Two or more elements,Chemically combined elements,More and definite proportions.

Explanation:

A compoundcan be definedas a substance which is composed of two or more elements, that are combined together chemically.

These constituents elements are present in definite proportion and quantities. The composing elements of a compound can be separated only by the means of chemical procedures. A compound is composed of more than one type of atom.

Hence answer could be:

Two or more elements,

Two or more elements,Chemically combined elements,

Two or more elements,Chemically combined elements,More and definite proportions.

You believe that the cytosolic protein p007 is involved in mediating growth hormone-stimulated proliferation in cells. You wish

Zinaida [17]

Answer:

Following are the answer to this question:

Explanation:

In option a:

There are many ways, which can be defined as follows:

It keeping cells "qualified," use heat shock and handle ions like Ca and ice incubating.
It uses Micro-injection with DNA.
It uses the biolistics or even the process of gene-gun.

The stable cell charts indicate simple and definitive outcomes when their relationship to specific results. Moreover, relative to temporary cell lines, findings are more reliable and error-free. These lines also easily break and much less.

In option b:

Radio tests including linking tests could be used

The Ligand Binding Assays is an analysis, that is based on the binding of ligands to antibodies, or other macromolecules. Its existence and distance of formed ligand-receptor complexes are defined using a system of measurement that is usually electrical or fluorescent.

In option c:

The method for measuring the levels of cell growth is accessible and the Another way is to measure the metabolism within the same cell. So many color pigments were also accessible that can permeate an organism as well as react with some proteins as well as other factors, and that can effectively identify a color final product.

Throughout relation to the amount of metabolism exercise, cell proliferation could be evaluated by researching one or even more cell markings. The BrdU limited liability assessment is a very well-published illustration.

Its specific antibody can detect BrdU and high BrdUincorporations levels are linked to high levels of cell proliferation. Command cell without DNA receptor growth hormone.

In option d:

The cell growth will stop after each use of RNA interference ( RNAi). The p007 formation as well as the effect on growth caused by the intrusion will be a goal. If development is delayed effectively, the theory will be tested successfully to a cell without any of the required DNA. The RNAi is the free cell

pantera1 [17]

The usage of EHR can enable the training to adjust all the more effectively to the new framework, which will provide profit for patients, doctors and staff.

Explanation:

In the initiation process EHR includes a multidisciplinary way to deal with set up the new framework, guarantee protection and security consistence, plan rehearse work process and also they deal with appropriation procedure.

There are nine steps for successful implementation of EHR they are Create an implementation team, Configure the software, Transfer data, Providing the physician liaison ROI, Driving referrals through physician preference.

The skills are needed in health information technology with the expanding usage of electronic well being records and the utilization of illness .

In the event the training is recorded as paper based and the longitudinal record is an essential idea for the training member.

The advantages and disadvantages of using this software analyzing chart is the utilization of subjective information examination programming incorporate being liberated from manual and administrative errands, sparing time and having the capacity to manage a lot of subjective information.

Thus the analysts have methodological ways to deal with utilizing subjective information investigation programming as they could fit between research strategies and structure.
