Answer:

Womersley numbers :  22.25 , 5.96 , 3.72

Explanation:

Calculate the Womersley number if the heart rate = 70 bpm

For the Human Aorta

∝ = r [tex]\sqrt{\frac{wp}{u} }[/tex]  ------ ( 1 )

r = radius  = 15 mm = 0.015 m

w = 2πf = 2 * π * 70 = 439.82

p = density of blood = 1060 kg/m^3

u = 0.035 P = 3.5 cp = 3.5 * 10^-3 Ns/m^2

Back to equation ( 1 )

∝ = 0.015 * [tex]\sqrt{\frac{439.82*1060}{60*3.5*10^{-3} } }[/tex] = ( 0.015 * √466209.2 / 0.21 )  = 22.35

 For Carotid artery

r = 0.8 cm / 2 = 0.4 cm = 0.004 m

w = 2πf  = 439.82

Womersley number =  ( 0.004 * √466209.2 / 0.21  )

                                = 0.004 * 1489.981 = 5.96

For Femoral artery

r = 0.5 cm / 2 = 0.25 cm = 0.0025 m

Womersley number = 0.0025 * √466209.2 / 0.21  )

                                = 0.0025 * 1489.981 = 3.72

The flow is unsteady because of the varying Womersley numbers

Answer and Explanation:

Many elements can limit population growth. The main elements that can cause this are the lack of resources necessary for the life and development of living beings and the lack of space to be taken by them. In relation to weeds, these resources can be the availability of sun, amount of soil, soil fertility, availability of water and space. However, these plants are very resistant to the lack of these resources, and what most limits their growth is human interference.

Weeds are unfavorable to agriculture and other human activities. This makes humans fight the population growth of these plants using chemical products and even physical strategies. This interference prevents weeds from taking over the world.

T Cells is another answer for this question!

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.

Answer:

Hand = 75%

No hand = 25%

Explanation:

It's the same thing as last time. Since 3 of them are heterozygous and have 1 dominant allele, they have the dominant trait. And since one of them only has recessive alleles then it should have the recessive traits.

So the hand should have 75% and no hand has 25%.

Answer:

A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.

EDGE 2021

Answer:

-70 mV

Explanation:

Given that Neuron A and Neuron B interact with Neuron C

Neuron A produces ; - 2mV of IPSP  and fires 6 times

Neuron B produces ; 3mV of EPSP and fires 4 times

Resting potential = - 70mV

threshold = - 50mV

The resulting membrane potential in neuron C

= -70 + 6(-2) + 4(3)

= -70 - 12 + 12  = -70 mV

Answer:

4th Option, share a common ancestor.

Explanation:

If two organisms have similar traits of DNA they probably share a common ancestor is the most suitable option to fill the blank.

When the two organisms have similar traits of DNA they probably share a common ancestor.

When the genes are shared so it preserved the ancestor record where they share with each other and excludes the bacteria.

And, if the DNA is the same for two organism so they would share the a common ancestor.

hence, the last option is correct.

Answer:

density-dependent, top-down factor

Explanation:

In biology, limiting factors are resources and other conditions in the environment whose presence/availability limit the population growth rate. Density-dependent factors refer to the conditions whose effects on the size/growth of the population vary depending on the population density. Some examples of density-dependent factors include diseases, competition, and predation, etc. These factors can exhibit a positive or negative correlation with the population size. Moreover, bottom-up population control (species limitation by resources) refers to limitations placed by resources allowing growth (e.g.,  food source or habitat), while top-down population control (limitation by enemies), refers to limitations placed by factors that control the death rate in the population (e.g., predation or diseases).

Answer:

- Ecological levels to consider in this study: organism, population and community

- Approach: I would use an observational approach to study this bird species

Explanation:

The levels of the ecological organization include the organism, population, community, ecosystem, and biosphere (from simplest to most complex). In this exploratory study, it is imperative to consider: 1-morphological, physiological and behavioral adaptations of the bird species (i.e., organismal-level), 2- size/density/structure of the bird population (i.e., population-level), and 3-interactions between bird population and other populations (i.e., community-level). The higher ecological levels, i.e., ecosystem-level (relationships between the community and abiotic factors ) and biosphere-level (biosphere =  planet Earth), can be in this case disregarded because this study is centered on a focus bird species. Moreover, it is expected to apply an observational strategy because nothing is currently known about the focus bird species. The experimental and modeling approaches seem more suitable to test a particular hypothesis being discussed (it is not the case for this study).

Answer:

Scalar quantities are quantities that are described only by a magnitude.

Of the babies that survive, however, few will have birth defects related to the exposure, regardless of how much radiation they were exposed to. Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain.

Answer:

The correct answer is C. In North and South America, a majority of the population is located on the coasts.

Explanation:

Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.
