write meaning of demoghraphy
Answer:
Demography is the study of human populations – their size, composition and distribution across space – and the process through which populations change. Births, deaths and migration are the 'big three' of demography, jointly producing population stability or change.
Explanation:
Hope it helpful
Answer:
Explanation:
Demography means study of population.It is derived from greek work 'Demos' which means people and 'graphein' which means study.The woed was first coined by Achille Guillard in 1855.But John Graunt is known as the father of demogrphy because he described population in demographic way.

# difference between monocyclic & polycyclic disease.
Answer:
The monocyclic pathogen follows the black arrows to complete its cycle. Polycyclic pathogens follow the red arrows for the majority of the season and the black arrows at the end of the season. In order for a disease to develop, a pathogen must be present and successfully invade plant host tissues and cells.

Individual amoebae of the slime mold Dictyostelium discoideum aggregate to form a spore-producing fruiting body. Cheaters make spores, but do not contribute to the stalk. Since many more spores with cheating genotypes are dispersed, they have higher fitness. Why does directional selection not lead to fixation of the cheater genotype
Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.

nvision in a family the mother has breast cancer and retinoblastoma (both conferred by recessive alleles on chromosome 17, and the two loci are on the same arm of this chromosome and 3 centimorgans apart), while the father does not carry any of these recessive alleles. What is the probability of their daughter having both cancers
Answer:
0%
Explanation:
Two genes/loci are linked when they are located on the same chromosome. Recombination, also known as crossing over, refers to the exchange of genetic material between non-sister chromatids during meiosis. One centimorgan (1 cM) is a genetic measurement of the distance between two loci on the same chromosome in which 1% crossing over occurs. In this case, the mother is an unaffected carrier who has one copy of both linked mutations (i.e., of both breast cancer and retinoblastoma mutations), thereby the expected frequency of recombination in the female meiosis is 3% (3 cM). Moreover, and since the father is an unaffected individual (who does not carry any of these recessive alleles) and both breast cancer and retinoblastoma conditions are caused by recessive somatic mutations, the probability of their daughter having both cancers is 0%, (offspring always receive one copy of each autosomal/somatic chromosome from the mother and one copy from the father).
which organisms replicate cells by mitosis?
a. animals and bacteria
b. bacteria and plants
c. animal and plants
d. archaea and bacteria
e. archaea and plants
Answer:
d.??????????????????
Answer: C!
Explanation: eukaryotic cells may divide via either mitosis or meiosis. only sexually reproducing eukaryotes can engage in meiosis. all eukaryotes — regardless of size or number of cells — can engage in mitosis.
Having no cell nucleus, archaea do not reproduce via mitosis; rather, they procreate using a process called binary fission. So D AND E are eliminated. And so is B because that has bacteria.
SO FINAL ANSWER; mitosis happens in eukaryotes, plant and animal cells
How do heart rate and cellular respiration relate to each other?
Answer:
Several changes take place in the body to enable this: the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

Duckweed is a tiny floating aquatic plant that can reproduce so rapidly that it can completely cover the surface of small fish hatchery ponds. One proposal to limit the growth of this invasive plant is to use colored panels to shield the ponds, inhibit photosynthesis, and kill this pest. What color filters would you order for the panels in this project
Answer:
Green color filter
Explanation:
It is given that Duckweed grown on water and covers all part of the pond very rapidly. In order to limit their growth is proposed to use a color panel so as to shield the ponds and inhibit photosynthesis process and also kill the pests.
So a green colored panels can be used to shield the pond. This is because the photosynthetic pigments such as the chlorophylls absorbs all the green frequencies of the visible light except for the wavelength that corresponds to the green color. Therefore, by using a green filter, the wavelength corresponding to blue, yellow, red and purple colors are absorbed. Thus the plants would not be able to use the green light for the process of photosynthesis. This would help in limiting the growth of the duckweeds.
what is the relationship between bacteria and the bacteriophage??
Answer:
We have bacteria that live on us, and bacteria have bacterial viruses that live on them. These viruses are called bacteriophages . Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA (or RNA) packed within a protein coat. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces them cell to produce viral components.

resources are you using by operating it?
Answer:
copper
Explanation:

human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

Which of the following would eat a hamburger with lettuce on it?
A) carnivore
B) detritivore
C) herbivore
D) omnivore
An Omnivore would eat a hamburger (animal) with lettce (plant) on it. Therefore option (D) is correct.
What do you mean by Omnivore ?
An animal classified as an omnivore consumes both vegetation and other animals. Some omnivores, such as carnivores that consume herbivores and other omnivores, will hunt and consume their meal. Some individuals are scavengers and will consume dead things. Many people eat eggs that belong to other species.
Not all types of plants are consumed by omnivores. Omnivores, unlike herbivores, are unable to digest some components of grains or other non-fruit-producing plants. However, they are able to eat fruits and vegetables. In this simulation, some of the insect omnivores are pollinators, which are crucial to the life cycle of several plant species.
Therefore, omnivore is the correct option (D) among other options.

I need help
Answer:
Krebs cycle and electron transport chain
Explanation:
Energy in form of ATP, which is needed by all living cells, is produced from a cell process called CELLULAR RESPIRATION. Cellular respiration is composed of three other processes depending on the availability of oxygen: glycolysis, Krebs cycle and electron transport chain.
Overall, glycolysis which takes place in the cytoplasm produces 2 molecules of ATP while the Krebs cycle and electron transport chain (ETC) produces a collective accumulation of 34 ATP molecules.

‘Plant and animals are interdependent on each other’, Why do they depend on each other. Write three points to justify your answer.
Answer:
Animals are consumers and they all depend on plants for survival. Some eat plants directly, while others eat animals that eat the plants. In turn, some plants depend on animals to help spread their seed. Decomposing animal carcasses can also provide nutrients for plants to grow.
Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal

What makes human beings different from other animals?
Answer:
There are many characteristics in humans that can define us to be different than other animals. For example, our body. Humans are generally more flexible than animals. One can bend in different ways while other animals are minimalistic in comparison to our flexibility. Another example is our life span. Humans have more life span than most animals but not all. Many animals have lesser life span from days, months to few years with exception of tortoise, elephants which have more than ourselves. Like I said in the beginning, there are many more traits that differ us from other animals.
