how can fear be a barrier to help seeking
Explanation:
Fear is a barrier as people fear being judged for things as there might be a stigma attached to it. When people are judged their problem isn't solved and instead worsened and they will feel compelled to keep their problems to themselves.
To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column
Answer:
IgG molecule, p53 molecule, actin molecule, histone molecule
Explanation:
In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.
In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

A. Excretory
B. Muscular
C. Endocrine
D. Skeletal
Answer:
Skeletal
Explanation:
Think about the bone marrow.
Answer:
D. Skeletal
Explanation:
blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

The Sun has a diameter of approximately 1,391,400 kilometers. How big would the Sun be in your scaled-down model of the solar system? Explain how you scaled the Sun’s diameter to fit into your model, and describe how its size compares to the planets.
Answer:
About 100 times more than other planets.
Explanation:
The Sun would be about 100 times bigger than the earth planet in the scaled-down model of the solar system because in the reality the size of sun is 109 times more than the earth so making a model more perfect and nearer to reality we have to maintain the diameter of the sun more than 100 times than the earth and other planets.

Explanation:
Human red blood cells can live from two to four months without a nucleus, and yet they continue to synthesize hemoglobin. This Group of answer choices is a chemical process that does not require continued living pathways; the red blood cells are essentially dead after they lose their nuclei. suggests that there is a low level of RNA polymeraseto degrade the mRNA. means that the necessary ribonucleases are continually translating DNA. means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present.
Answer:
means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present
Explanation:
Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.
Joel notices that there is not much difference between low and high tide. what is happening?
Please be nice
Answer:
This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise. So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around full and new moon.

A man and a woman have recently married , unfortunately they didn't have any children yet. What do you think are the reasons for delayed pregnancy ?
Answer and I will give you brainiliest
Answer:
Late ovulation
explanation
it can delay pregnancy, but that doesn’t mean it won’t happen. It’s entirely possible to conceive when you ovulate later in the cycle; the trick is to be as in tune with your body as possible. By knowing exactly what to look out for, you'll soon be able to tell when you are eventually ovulating.
"Several common reasons for a late period include stress, low body weight, obesity, different hormonal syndromes, birth control, and chronic diseases,"
Which answer helps to explain why carbon atoms tend to make 4 covalent bonds
Answer:
Carbon atoms tend to make 4 covalent bonds because the valence shell needs 8 electrons.
Explanation:
For atoms to be stable, they must have filled outermost energy shells called valence shells. This is called the octet rule.

What are the possible results of speciation?
Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Explanation:
In cats produce many different coat colors. Tabby fur color can be produced by AA or Aa, black is aa. Another gene pair is epistatic to the gene for fur color. When present in its dominant form (WW or Ww), this gene blocks the formation of fur color resulting in offspring with white fur (ww offspring have normal fur). Determine the proportions of offspring from the following cross:______.

Hello. It is not possible to make a report of your class in the laboratory, without having attended that class. For this reason, I will show you how this report can be written. I hope it helps you.
You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.
In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.
Finally, you should end the report with a conclusion, showing what you have learned from this experience.

A population of 6000 ants lives inside a dead log that measures 3 square meters. What is the population density of the ants?
Answer:
2000 ants per square meters.
Explanation:
The population density, D, of a population can be calculated by dividing the total number of individuals by the area covered by that population. That is;
D = N/A
Where;
D = population density
N = population of individual organism
A = area covered (m²)
According to this question, a population of 6000 ants lives inside a dead log that measures 3 square meters. Hence, N = 6000 ants, and A = 3m²
Therefore, the population density (D) = 6000/3
= 2000
The population density is 2000 ants/square meter.
