i think ur QUESTION is incorrect

MAGNESIUM oxide is it

Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that OCCURS naturally as periclase and is a source of magnesium (see also oxide). It has an empirical FORMULA of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic BONDING.

Production of RBCs occurs in BONE marrow. Bone marrow is a soft spongy area in our BODY.

It makes blood cells. In a adult body the bone marrow PRODUCES the most blood cells are found in hip bones, SHOULDER bones, ribs, breast bone, skull.

The bone marrow contains two types of tissues.

In first tissue the stem cells are developed into red blood cells, WHITE blood cells. Another one stores the fatty tissues.

RBCs of the BLOOD contain hemoglobin an iron compound.

Hemoglobin helps to transport oxygen to the tissue. Each hemoglobin contains subunits HEMES, which are what GIVE blood its red color.

It develops in BONE marrow that becomes red blood cells. When the red cells die then the hemoglobin is broken up into MANY parts.

Then the interior iron will transported to the bone marrow by proteins.

Answer:

Below are some of the STRUCTURES and functions of blood.

Explanation:

Blood contains red blood cells which TRANSPORT OXYGEN to the cells by use of haemoglobin.

Plasma present in blood controls coagulation factors, it controls the blood clotting process.

White blood cells contained in blood in the blood are transported to the area of infection. They help in the prevention of diseases in the body system.

Blood ALSO supports GROWTH of an organism by transporting nutrients and waste in and out of the cell.

Blood DONATION is definitely a noble ACT. Many clinics and hospitals constantly require blood for SEVERAL purposes. This makes the IDEA of blood donation a noble gesture as it provides life-saving help to people and patients. ... Many people believe that blood donation is harmful for their body, HOWEVER, this is untrue.

evolution is the CHANGES in inherited TRAITS of a population from generation to generation. mutation in these GENES can produce new and altered traits ,RESULTING in hereditary changes in organisms. HEREDITY is the process of passing of traits from one generation to the next generation.

According to the recent study, published in Psychological Science Feb. 1, ANDERSON found that we interpret a person’s emotions by analyzing the expression in their eyes – a process that began as a universal reaction to environmental stimuli and evolved to communicate our deepest emotions.

For example, people in the study consistently associated narrowed eyes – which enhance our visual discrimination by blocking light and sharpening focus – with emotions related to discrimination, such as disgust and suspicion. In contrast, people linked open eyes – which expand our field of vision – with emotions related to sensitivity, like fear and awe.

“When looking at the face, the eyes dominate emotional communication,” Anderson said. “The eyes are windows to the soul likely because they are first conduits for sight. Emotional expressive changes around the eye influence how we see, and in turn, this communicates to others how we think and feel.”

This work builds on Anderson’s research from 2013, which demonstrated that human facial expressions, such as raising one’s eyebrows, arose from universal, adaptive reactions to one’s environment and did not originally signal social communication.

Both studies support Charles Darwin’s 19th-century theories on the evolution of emotion, which hypothesized that our expressions originated for sensory function rather than social communication.

“What our work is beginning to UNRAVEL,” said Anderson, “are the details of what Darwin theorized: why certain expressions look the way they do, how that helps the person perceive the world, and how others use those expressions to read our innermost emotions and intentions.”

Anderson and his co-author, Daniel H. Lee, professor of psychology and neuroscience at the UNIVERSITY of Colorado, Boulder, created models of six expressions – sadness, disgust, anger, joy, fear and surprise – using photos of faces in widely used databases. Study participants were shown a pair of eyes demonstrating one of the six expressions and one of 50 words describing a specific mental state, such as discriminating, curious, BORED, etc. Participants then rated the extent to which the word described the eye expression. Each participant completed 600 trials.

Participants consistently matched the eye expressions with the corresponding basic emotion, accurately discerning all six basic emotions from the eyes alone.

Anderson then analyzed how these perceptions of mental states related to specific eye features. Those features included the openness of the eye, the distance from the eyebrow to the eye, the slope and curve of the eyebrow, and wrinkles around the nose, the temple and below the eye.

The study found that the openness of the eye was most closely related to our ability to read others’ mental states based on their eye expressions. Narrow-eyed expressions reflected mental states related to enhanced visual discrimination, such as suspicion and disapproval, while open-eyed expressions related to visual sensitivity, such as curiosity. Other features around the eye also communicated whether a mental state is positive or negative.

Further, he ran more studies comparing how well study participants could read emotions from the eye region to how well they could read emotions in other areas of the face, such as the nose or mouth. Those studies found the eyes offered more robust INDICATIONS of emotions.

This study, said Anderson, was the next step in Darwin’s theory, asking how expressions for sensory function ended up being used for communication function of complex mental states.

What are U SAYING ...........

Yes LACTIC ACID is present in a milk
it is made up of lactose protein ENZYME

The precautions are :-
1)We should not take DOSE of antibiotics.
2)Antibiotics should not be taken EMPTY stomach.
3)We should complete the dose of antibiotic as ADVISED by the doctor.
4)We should take antibiotic only after consulting a doctor.

According to the MOLECULAR theory blood are MADE with RED blood CELLS.

These blood cells are made up with a type of protein name hemoglobin.

Each hemoglobin contains subunits Hemes, which are what give blood its red color.

More specifically, INTERACTION between iron and oxygen made the blood cells red.

The inner membrane of mitochondria FOLDS as many times and CREATES LAYERED structures called cristae. The fluid contained in the mitochondria is called the MATRIX. The folding of the inner membrane increases the surface area inside the organelle.

When we have any injuries the blood COMES out and the bleeding stops when a CLOT forms.

The multistep process of clot formation is called coagulation.

Coagulation is a process in which blood changes from a LIQUID state to gel and block and then HEAL a wound/cut and STOP the bleeding.

We KNOW that the particles of matter have spaces between them... And in case of liquids, there is small interparticle FORCES between the particles of LIQUID... And so the diver can easily cut the WATER and swim

Because it CAUSE many INJURIOUS to our HEALTH if it can cutt off that's why veins does nt have thick WALLED

Osmosis is the MOVEMENT of water MOLECULES from an area of high water concentration to an area of LOW water concentration through a partially/selectively PERMEABLE membrane.

When our digestive system brook down food using mechanical and chemical processes, our body is left with the key nutrients it needs to survive.

Osmosis ALLOWS our body to absorb these nutrients into the intestines and individual cells.

Inertia is the resistance of any physical object to any change in its position and state of motion. This includes changes to the object's speed, direction, or state of REST. Inertia is also DEFINED as the tendency of objects to KEEP moving in a straight line at a CONSTANT velocity

Development of embryo-

1)The zygote divides REPEATEDLY to make a ball of hundreds of CELLS.This is CALLED an embryo.The embryo moves down the oviduct into the uterus.The embryo gets embedded in the soft and thick lining of the uterus.This is called implantation.

2)When the embryo settles down in the uterus, the woman is said to have become pregnant.The embryo starts growing into a baby.The embryo gets food and oxygen from the blood vessels in the lining of the uterus.

3)The cells of embryo begin to form specialised groups that develop into different tissues and organ of the baby.n unborn baby at an early stage of development in uterus is called an embryo.Te unborn baby REMAINS an embryo in the first eight weeks of pregnancy.

4)The embryo continues to grow and develop in the uterus to form a baby.The embryo gradually develops body part such as hands, legs, head, eyes and ears.

5)An unborn baby in the uterus at the stage when all the body parts can be identified is called foetus.

6)A HUMAN embryo becomes a foetus after about eight weeks of pregnancy.

7)It takes 38 weeks from the fertilisation of eggs to the formation of fully developed baby.When the development of foetus into a baby is complete, the mother gives birth to the baby.The fully formed baby comes out of mother’s body through vagina.
