If two organisms have similar traits of DNA they probably
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.
Two organism have the same traits: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.

How did the development of the sexual reproduction affect evolutionary change?
the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes in each offspring's chloroplasts wioll have been inherited from plant R
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%.
Why can't weeds take over the world? In other words, what limits the growth of populations?
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.

Rinderpest (a virus) has high mortality in wildebeest (a kind of herbivore), especially in young animals. From the early 1960s, after the elimination of a virus called rinderpest, the wildebeest population has increased dramatically from 1958 to 1978. The elimination of rinderpest impacted the wildebeest population. What type of factor is rinderpest
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).
For a typical human aorta, the diameter of the lumen is 30 mm and the thickness of the wall is 4 mm. Assuming a blood density of 1.06 gm/cc and a viscosity of 0.035 Poise, calculate the Womersley number if the heart rate is 70 bpm. Diameters for the carotid and femoral arteries of a typical human are about 0.8 cm and 0.5 cm, respectively. Compute the Womersley numbers for each of the arterial segments for the same heart rate and explain if the flows can be assumed steady or not.
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
Which of the following is true about the coasts of North and South America? O A. Little industry is located along the coasts, B. There are few cities and the population is sparse. O c. A majority of the population is located there. D. People go to the coasts only when on vacation,
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.

You are a researcher interested in a rare, highly endangered bird species that lives in a very remote area of the Amazonian rainforest. Almost nothing is currently known about this species’ diet, behavior, life-span, breeding system, or its interactions with other species. Use your knowledge of the definition of ecology, the scales at which ecological research is conducted, and experimental design.
1. Which ecological level (or levels) would you focus on in your research? Justify why you would choose this level (or levels), and explain why you would not choose the others.
2. Would you use an observational, experimental, or modeling approach to study this rare bird species? Why would the approach you chose be a better choice than the others for your study?
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:
Normal Eyes = 75%
Heart eyes = 25%
Explanation:
3 of the offspring in that punnet square have at least 1 dominant allele. And if an offspring has at least 1 dominant allele then it should have the dominant trait( which is normal eyes ). But if it only contains recessive alleles then it would have the recessive trait (which in this case would be heart eyes).
