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.

The image shows a group of fish.
Which type of social behavior is shown in the image?
Oherding
O dividing labor
O schooling
O flocking
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.
In this picture we can see that a group of fish is swimming from one place to other therefore it is called as schooling social behavior of the fish. Hence option C is correct.

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:
SIRT3 is a tumor suppressor gene that controls essential cellular processes including apoptosis, cell proliferation, survival and anoikis resistance
Explanation:
The Sirtuin-3 (SIRT3) gene encodes for a histone deacetylase enzyme involved in the epigenetic regulation of many essential genes, thereby controlling their expression levels. SIRT3 has a proapoptotic function that initiates apoptotic events in cancer cells. Moreover, SIRT3 also modulates cell proliferation and survival in both normal and tumorigenic cells by controlling the expression of genes that maintain Reactive oxygen species (ROS) at non-toxic levels. Finally, SIRT3 also mediates anoikis resistance (i.e., the resistance to detachment-induced cell death), thereby inhibiting tumorigenesis in cancer cells. It is for all these reasons that it has been proposed that SIRT3 represents a potential drug target for cancer therapy.

Identify the following particles as being charged or uncharged/neutral. If charged, indicate whether they are charged positively or negatively. (n = neutron, p = proton, e = electron)
*particle C
proton +20
electron -18
urgent ^^
Answer:
Particle A is negatively charged.
Particle B is neutral.
Particle C is positively charged.
Explanation:
Particle A is negatively charged because the number of electrons is more than number of protons so the particle gain negative charge. Particle A is neutral due to same number of proton and electron which cancels the effect of one another and become neutral whereas the Particle B is positively charged due presence of more number of protons as compared to number of electrons so the particle gain positive charge.

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.

Answer:
1. c . The life cycles of insects and animals all start from a fertilized egg.
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..
