CHEMICAL co-ordination in humans is DUE to the SECRETION of hormones from various glands in the body. The co-ordination is SPECIALLY due to endocrine glands SYSTEM in our body. Example:- Thyroid gland produces thyroxine hormone

What is force?

In physics, a force is any INTERACTION that, when unopposed, will CHANGE the motion of an OBJECT. A force can CAUSE an object with mass to change its velocity, i.e., to accelerate. Force can also be DESCRIBED intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Answer:

An female's internal reproductive organs are the vagina, uterus, fallopian tubes, cervix, and ovary. External structures include the mons pubis, PUDENDAL CLEFT, labia majora and minora, vulva, BARTHOLIN's gland, and the clitoris.

The female reproductive organs can be SUBDIVIDED into the internal and external genitalia (see the images below). The internal genitalia are those organs that are within the TRUE pelvis. These include the vagina, uterus, cervix, uterine tubes (oviducts or fallopian tubes), and ovaries.

Answer:

Explanation:

∆ Pollen interaction is the GERMINATION of the pollen grains on the stigma of the flower. There are several pollens but only one germinate and fuses with the FEMALE gamete while others degenerate. This process is called as pollen-pistil interaction as pistil (the female part of the flower containing stigma, style, and ovary) will select the compatible for itself.

Post-fertilization changes are the changes in the structure of a flower after the process of fertilization. These changes are as follows:

After fertilization the floral parts like SEPALS, petals fall off.

Pollination occurs inside the flowers.

The fusion of one MALE nuclei with egg results in the formation of an embryo.

The fusion of one male gamete with two POLAR nuclei forms the endosperm.

ANSWER:

METHANE is the answer...

1. Air

→ Oxygen is first most important thing for EVERY living thing on this planet. Without oxygen no one could survive for a minute. But human NEED clear air to survive, if the oxygen will be POLLUTED then it's going to be dangerous.

2. Water

→ Water is the second most important thing for a human, without water a human could survive for 3-4 days. Water keeps our body hydrated which, and if our body will be hydrated then our body will function well. If our body will not receive water it will gradually will start to dehydrate.

3. Food

→ Without food a human could survive for 1-3 week, food GIVES us energy to do work and give us nutrition for our survival. Food helps in developing our body. You can say it's the fuel of our body and if we will not receive food then our body will STOP developing and will stop functioning.

Explanation:

In vitro fertilization (IVF) is a complex series of procedures USED to help with fertility or prevent genetic problems and assist with the CONCEPTION of a child.

During IVF, mature eggs are collected (retrieved) from ovaries and fertilized by SPERM in a lab. Then the fertilized egg (EMBRYO) or eggs (embryos) are transferred to a uterus. One full cycle of IVF takes about three weeks. Sometimes these steps are SPLIT into different parts and the process can take longer.

Answer:

Explanation:

1) The stomach acts like a washing machine, churning the food around to break it into even smaller pieces.

2) MECHANICAL mixing of food in stomach occurs by peristalsis, which is WAVES of muscular contractions that move along the stomach wall.

3) This allows the MASS of food to further mix with the digestive enzymes.

4) Due to churning of food in stomach, a mixture that resembles thick cream called chyme is formed.

5) Hence we can call stomach as a churning machine.

Carnivores play an important role in keeping balanced ecosystem.Carnivores are curical in regulating and maintaining ecosystems.Through hunting ,carnivores maintains herbivores and thereby protecting vegetation from being too heavily gazed or browsed.

Get to know more about carnivores:⇟

Carnivores are crucial in regulating and maintaining ecosystems. Larger carnivores in particular are often keystone species, meaning that they play a disproportionately greater role in the health of their ecosystem than you would expect based on their numbers. Through hunting, carnivores maintain herbivore populations at a HEALTHY level, PREVENTING an OVERABUNDANCE of herbivores and thereby PROTECTING vegetation from being too heavily grazed or BROWSED. That in turn protects other plant and animal species that depend on a healthy vegetation assemblage for food or shelter.

Answer:

The shift in blood volume decreases thoracic venous blood volume (CV Vol) and therefore central venous pressure (CVP) decreases. This decreases right ventricular filling pressure (preload), leading to a decline in stroke volume by the Frank-Starling mechanism. On the transition from sitting in a chair to standing, blood is pooled in the lower extremities as a result of gravitational forces. Venous return is reduced, which leads to a decrease in cardiac stroke volume, a decline in arterial blood pressure, and an immediate decrease in blood flow to the brain.In space, where the familiar pull of gravity is missing, the head-to-toe gradient vanishes. Blood pressure equalizes and becomes about 100 mmHg throughout the body. ... Within two to three days of weightlessness, astronauts can lose as much as 22 percent of their blood volume as a result of that errant message.Many parts of the cardiovascular system (including the heart) are influenced by gravity. On Earth, for example, the veins in our legs work against gravity to get blood back to the heart. Without gravity, however, the heart and blood vessels change – and the longer the flight, the more severe the changes.When you stand up, gravity causes blood to pool in your legs and ABDOMEN. This decreases blood pressure because there's less blood circulating back to your heart. NORMALLY, special cells (baroreceptors) near your heart and neck arteries sense this lower blood pressure.Gravitational forces significantly affect venous return, cardiac output, and arterial and venous pressures. To illustrate this, consider a person who is lying down and then suddenly stands up. When the person is lying down (supine position), gravitational forces are similar on the thorax, abdomen and legs because these compartments lie in the same horizontal plane. In this position, venous blood volumes and pressures are distributed evenly throughout the body. When the person suddenly stands upright, gravity acts on the vascular volume causing blood to accumulate in the lower extremities. (Compare the size of veins in the top of your feet while lying down and standing.) Because venous compliance is high and the veins readily expand with blood, most of the blood volume shift occurs in the veins. Therefore, venous volume (Vol) and pressure (VP) become very high in the feet and lower limbs when standingLeft ventricular stroke volume also FALLS because of reduced pulmonary venous return (decreased left ventricular preload). This causes cardiac output (CO) and mean arterial pressure (MAP) to fall. If arterial pressure falls appreciably upon standing, this is termed orthostatic or postural hypotension. This fall in arterial pressure can reduce cerebral blood flow to the point where a person might experience syncope (fainting).

When a person stands up, baroreceptor reflexes are rapidly activated to restore arterial pressure so that mean arterial pressure normally is not reduced by more than a few mmHg when a person is standing compared to lying down. However, in order to maintain this normal mean arterial pressure, the person who is standing upright has increased systemic vascular resistance (sympathetic mediated), decreased venous compliance (due to sympathetic activation of veins), decreased stroke volume (due to decreased preload), and increased heart rate (baroreceptor-mediated tachycardia). PATIENTS with autonomic nerve dysfunction or hypovolemia will not be able effectively utilize these compensatory mechanisms and therefore will display orthostatic hypotension. Without the operation of important compensatory mechanisms, standing upright would lead to significant edema in the feet and lower legs in addition to orthostatic hypotension. Venous pooling and reduced venous return are rapidly compensated in a normal individual by neurogenic vasoconstriction of veins, the functioning of venous valves, by muscle pump activity, and by the abdominothoracic pump.  When these mechanisms are operating, capillary and venous pressures in the feet will only be elevated by 10-20 mmHg, mean aortic pressure will be maintained, and central venous pressure will be only slightly reduced.

When a standing person suddenly changes to the supine position, gravity no longer causes a shift in blood volume from the thoracic compartment to the legs and feet. Therefore, the blood volume in the thoracic (central venous) compartment as blood volume shift away from the legs. This increases preload on the heart, thereby increasing stroke volume, although the resulting increase in cardiac output will be tempered by a reduction in heart rate through vagal activation and sympathetic withdrawal. Sympathetic activation of the systemic vasculature is also reduced, which causes systemic vascular resistance to fall as the resistance vessels dilate. Blood feels gravity, too. On Earth, blood pools in the feet. When people stand, the blood pressure in their feet can be high -- about 200 mmHg (millimeters of mercury). In the brain, though, it's only 60 to 80 mmHg.

Answer

Sex is the hereditary difference between two individuals of same species. Sex is determined at the time of fertilization, when the male and female gametes fuse.

The process by which the sex of a PERSON is determined is called sex DETERMINATION.

Sex chromosomes are found in sex cells and are responsible for the determination of sex. These are X and Y chromosomes.

X and Y chromosomes are structurally different. In human BEINGS, the female has two X chromosome (XX) in the cells, males have one X chromosome and one Y chromosome (XY).

In female all ova produced possess X chromosome while in male, the sperm produced are of 2 types half X and half Y chromosomes.

Thus, the sex of the baby depends upon the male sperm X bearing sperm PRODUCES girl bady and Y bearing sperm produces bay baby.
