Explanation:
The fertilization of ovules from Plant Q by pollen from Plant R results in the production of seeds. What percent of the genes in each offspring's chloroplasts will have been inherited from plant R?
A: 0%
B: 25%
C: 50%
D: 100%
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%

what is psychological aspect of ageing
Answer:
Explanation: Psychological aging focuses on sensory processes, perception, coordination, mental capacity, human development, personality, and coping ability as they are affected by aging. In most societies, older people are generally viewed as a group of with common characteristics and needs. Older age is usually viewed as a state, a stage or an event.
Ageing - Physical and Psychological Changes. Pathological Ageing
The process of aging has been around as long as life itself. All living organisms pass through three broad stages from conception to death, which are maturation, maturity and aging. Aging affects everyone because nearly everyone has the potential to grow old and all the societies in which we live have older members (Macdonald, 1997). Gerontology is the use of reason to understand aging. The term was used to refer to the scientific study of aging, but nowadays it includes the study of aging using views from other disciplines such as humanities, social policy and human services. To correctly understand aging, knowledge from a variety of sources is needed, therefore gerontology includes the results of research on aging from all academic disciplines and fields of professional practice. There are four interrelated aspects to the study of aging, which are, physical, psychological, social psychological and social. The study of physical aging examines the causes and consequences of the body’s declining capacity to renew itself and the means for preventing, treating, or compensating for illness or disability caused or related by physical aging (Atchley, 1997). Psychological aging focuses on sensory processes, perception, coordination, mental capacity, human development, personality, and coping ability as they are affected by aging.
In most societies, older people are generally viewed as a group of with common characteristics and needs. Older age is usually viewed as a state, a stage or an event. In reality, older people are not a homogenous group, but rather highly diverse individuals. The factor that is common to all older people is the accumulation of more numerous life experiences over a greater period of time than those of younger people (Bowling & Dieppe, 2005). Aging is defined as the process of becoming older, a process that is genetically determined and environmentally modulated. Aging is something that everyone will have to experience. Everyone will have to grow old. Normal ageing brings about changes in the body and mind, therefore both physical and psychological. These symptoms are all part of ageing, but also some might not be due to normal aging but rather due to diseases, which can be treated or remedied. Therefore, it is important to learn about normal ageing in order to be able to distinguish between disease and normal ageing so to be in a position to seek proper and early treatment for the disease.
Changes related to normal Ageing
Vision
Vision is usually impaired due to ageing. These can be due to presbyopia. There can also be overflow of tears due to blockage of drainage ducts and well as old people may have dry eyes (Chopdar et al., 2003). In order to minimise such problems it is important to check for presbyopia and wear suitable lens. Also it is important to seek a doctor’s advice on the need of any eye drops, only against doctor’s prescription.
Hearing
Due to ageing hearing may be impaired. Hearing loss is common due to old age (Bates, 1993). In order to be able to adjust due to this condition lifestyle modifications may help to overcome this situation. This may include the consideration of hearing aids. Also the installation of loudspeakers to devices such as door bells and telephone units.
Sensation
Sensation also if affected due to normal ageing. Old people have a blunted touch sensation, especially near the tips of the fingers and toes. Also there is a blunted sensation of temperature (Macdonald, 1997). Therefore, in order to counter act these changes, it is important for old people to wear well fitted shoes and take good care of their feet. If any wounds are present these should be inspected regularly. Also it is important to wear suitable clothes according to the day’s weather conditions.

Answer:
Quantity, information content, packing and replication of chromosome.
Explanation:
Quantity, information content, packing and replication of chromosome are the major differences that is present between the organization of DNA in viruses and bacteria as compared to eukaryotes. The quantity of DNA in bacteria and virus is less than eukaryotes. In virus and bacteria, DNA is arranged into a single circular chromosome while on the other hand, in eukaryotes, DNA is arranged into several linear chromosomes.

Explanation:
Accelerate 2022
The mantle is so hot that it allows the rocky material to flow gradually. The correct option is D.
What are the layers of Earth?The crust, mantle, outer core, and inner core are the four principal parts that make up the earth's structure.
Each layer has a distinct chemical make-up, physical state, and potential to affect life on the surface of the Earth.
The crust, mantle, and core are the three layers that make up the earth. This stratum of the earth lies on the surface and is composed primarily of granite and basalt solid rock.
Oceanic and continental crust are the two different types. The majority of the oceanic crust is made of basalt and is denser and thinner.
The Earth's mantle is regarded as being semi-solid. Because the mantle is so heated, the rocky material can flow gently.
Thus, the correct option is D.

Explain how the discoveries by Rosalind Franklin
helped Watson and Crick build an accurate
model of DNA.
Answer:
In 1951 Franklin joined the Biophysical Laboratory at King’s College, London, as a research fellow. There she applied X-ray diffraction methods to the study of DNA. When she began her research at King’s College, very little was known about the chemical makeup or structure of DNA. However, she soon discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick to suggest in 1953 that the structure of DNA is a double-helix polymer, a spiral consisting of two DNA strands wound around each other.

2. d . A bee goes through a pupa stage, while the grasshopper goes through a nymph stage.
3. b . I and II
Explanation:
The egg fertilization is very important for the emergence of almost all organisms. If the egg is fertilized then it will change into an organism otherwise no organism is produced from that unfertilized egg. The bees has four distinct life stages i.e. the egg, larva, pupa and adult whereas grasshopper has three stages i.e. egg, nymph, and adult. A moth and an eagle both start their life cycle as a fertilized egg and moth and an eagle both hatch from an egg which is laid by the mother outside of their body..

1. If an animal cell is placed into a solution whose concentration of dissolved substances is
higher than that inside the cell(osmosis). What will happen?
Answer:
Water will move out of the cell causing it to eventually shrink.
Explanation:
The tonicity of solutions determine the direction of water movement. Hypertonic solution is a solution whose concentration is higher than that of its external solution while hypotonic solution is a solution whose concentration is lower than that of its external solution. In this case, an animal cell is placed into a solution whose concentration of dissolved substances is higher than that inside the cell.
This means that the extracellular solution is HYPERTONIC to the cell's solution. Based on OSMOSIS, which is the movement of water from a region of lower solute concentration (high water conc.) to a region of higher solute concentration (low water conc.) via a semipermeable membrane, water will move out of the animal cell into the extracellular solution via the cell membrane (semipermeable membrane).
This movement of water out of the cell will eventually cause it to shrink and die.

The image shows a group of fish in which Schooling type of social behavior is shown in the image. Hence option C is correct.
What is Schooling?In biology, a group of fish that stay together for social reasons are shoaling, and if the group is going from one place to other in the same direction in a coordinated manner then it is called as schooling.
Flocking is a behavior in which objects move or work together as a group. this is seen in the birds, when a group of birds goes for a work we call it as flock of birds.
when a subgroups of animal is performing different tasks in a big group is called as dividing labor behavior.
