What is the difference between Hinduism and Nirvana

Answers

Answer:

The most ancient texts of Hinduism such as the Vedas and early Upanishads don't mention the soteriological term Nirvana. This term is found in texts such as the Bhagavad Gita and the Nirvana Upanishad, likely composed in the post-Buddha era. The concept of Nirvana is described differently in Buddhist and Hindu literature. Hinduism has the concept of Atman – the soul, self asserted to exist in every living being, while Buddhism asserts through its anatman doctrine that there is no Atman in any being. Nirvana in Buddhism is "stilling mind, cessation of desires, and action" unto emptiness, states Jeaneane Fowler, while nirvana in post-Buddhist Hindu texts is also "stilling mind but not inaction" and "not emptiness", rather it is the knowledge of true Self (Atman) and the acceptance of its universality and unity with metaphysical Brahman.

Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.

A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.

B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.

C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.

D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.

E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

Explanation:

can u plz explain the role of the digestive, endocrine, and excretory systems in maintaining homeostasis.

Answers

Answer:

Following are the roles of the digestive, excretory and endocrine systems in terms of homeostasis:

The endocrine system regulates the secretion of various hormones and homeostatic mechanisms in response to signals of the hypothalamus and pituitary glands.The excretory system maintains homeostasis by purifying the blood and getting rid of toxic waste from the  blood.The digestive system is mainly involved in the transfer and regulation of nutrients from food.

Explanation:

Role of Endocrine System:

The endocrine system mediates all the chemical signaling in the body.

Hormones are chemical messengers that the endocrine system uses to maintain chemical homeostasis.

Endocrine system manages glucoregulation by controlling the secretion of the hormones glucagon and insulin by the pancreas. Low and high blood sugar levels are sensed by the brain which then signals the endocrine system to release glucagon and insulin respectively.

The endocrine system is also indirectly involved in thermoregulation. A low core temperature signal received by the hypothalamus initiates the release of TSH by the pituitary gland and then that of T3, T4 thyroid hormones that stimulate shivering thermogenesis in the skeletal muscles.

Role of Digestive System:

The digestive system regulates the amount of nutrients absorbed in the body.

Although the absorption of nutrients in food is not exactly according to bodily needs, the absorption of dietary iron and calcium is strictly regulated by the digestive system.

Role of Excretory System:

The excretory system carries out osmoregulation which is the maintenance and regulation of water and salt levels in the blood.

The excretory system regulates the excretion of toxic waste from the blood.

Excess water, salts, urea and bilirubin (produced as a result of RBC break down) are some of the excretions.

C. They give off radioactive isotopes when an electrical charge is applied.
D. They have been exposed to large amounts of radioactivity in the atmosphere.

Answer: I think the correct answer is A or B.

Explanation: But i highly suggest B

Radiocarbon  dating is a feasibe method because the isotopes involved  decay at a constant rate.

What is radiocarbon dating?

The term radiocarbon dating refers to the use of carbon in the establishment of the age of a sample. This is usually done by the use of carbon -14 isotope.

The reason why radiocarbon dating can be used to determine the accurate age of these items is that they contain radioactive isotopes that decay at a constant rate.

Tell me something interesting about protozoa (at least 5 facts)

Answers

Answer:

an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

Hello there!!

I love protozoa so this should be fun.

1. Protozoans are unicellular beings that live in wet environments.

2. Protozoans have 2 prevalent ways of feeding:

a) the most common is utilized by heterotrophs like amoeba. An amoeba extends its elastic body until it completely surrounds the victim. Then the amoeba simply has to digest its food.

b) The second most common is through cilia. Paramecia use this method. The hair-like cilia in its mouth catch hold of food and push the meal into the paramecium's digestive tract.

3) The only protozoan to have its own family is Euglena.

4) Euglena has its own family because it has chloroplasts (meaning it can undergo photosynthesis) but it can also feed like a heterotroph. Because Euglena exhibits both plant and protozoan qualities, it has its own category.

5) Rotifers move by two spinning wheels of cilia. This type of propulsion makes the rotifer a speedy little protozoan.
