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.

what is angiosperm in plant
Answer: a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.
Explanation:
In the world of purple people eaters, one eye (E) and one horn (H) are dominant traits. Purple people eaters
can also have two eyes (e) and two horns (h), which are recessive traits.
Perform a dihybrid cross among a male who is heterozygous for both traits and a female
who is heterozygous for both traits. Use the results for your prediction below.

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%.

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.

What is Climate Change?
Explain your answer.
What is Climate Change?
Climate change is a change in the usual weather found in a place.
How it helps us:
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
How it works:
As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.
How it affects us:
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

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).
1) Define biodiversity in your own words:
2) Why is biodiversity important?
Answer:
Explanation:
1.) Biodiversity is variety in an ecosystem and the living things inside of it. It means all the different species and creatures that live on the planet.
2.) Biodiversity is important because it provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, erosion control, and crop and tree pollination. Each species ina n ecosystem has a role to play.

True or False: Purine is connected to pyrimidine using oxygen bonds.
Answer:
False
Explanation:
In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).
An electrocardiogram (ECG) provides information about: Group of answer choices the pressure of blood in the heart chambers the rhythm of heart contractions the speed of blood flow through the blood vessels the amount of oxygen in the blood as it leaves the heart
Answer:
the rhythm of heart contractions.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
An electrocardiogram (ECG) provides information about the rhythm of heart contractions.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
