What provides information about the body position with respect to gravity?​

Biology

Answer:

Centre of Gravity

The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.

Centre of Gravity in the Human Body

In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.

user100 [1]

Answer:

A fast increase in blood sugar causes a rapid increase in insulin, which is the hormone responsible for allowing glucose to enter cells. High insulin levels cause glucose levels to quickly fall, which can then cause you to feel hungry again, prompting you to take in more calories.

Explain how phospholipids form cell membranes.
dem82 [27]

Answer:

Phospholipids are able to form cell membranes because the phosphate group head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating). They automatically arrange themselves in a certain pattern in water because of these properties, and form cell membranes.

worty [1.4K]

Answer:

(D) all of the above

Explanation:

The rough endoplasmic reticulum is part of the endoplasmic reticulum, the other one is known as the smoother endoplasmic reticulum.

1. This rough endoplasmic reticulum is considered rough because it has ribosomes bound to it.

2. Also, it is part of the membrane system found throughout the cell's cytoplasm, even though its density is considered to be higher in some places, such as near the nucleus.

3. It is also is connected to the nuclear envelope or membrane

Some of its functions include

1. It produces antibody in certain leukocytes

2. It produces insulin in pancreatic cells

Hence, in this case, the correct answer is Option D "all of the above."

Sauron [17]

Answer:

The correct answer is

1. A rabbit living in  a desert has long ears  to disperse heat- abiotic factor.

2. A moth immediately  dives to the ground  when it hears a bat- biotic factor.

3. A lizard stays warm  by sunning itself  on a rock- abiotic factor.

4. A cactus has spines  instead of leaves  to help conserve water- abiotic factors.

5. A petunia is  bright red to  attract hummingbirds- biotic factor.

6. A stick-bug blends in  with trees to hide  from predators- biotic factor.

Explanation:-

The environment includes both abiotic and biotic factors which can affect the ecosystem. Living elements like plants and animals which affect ecosystem are known as biotic factors while the non-living elements which include air, water, temperature are called abiotic factors.

In the given question the options affected by the biotic factors due to bat, due to hummingbirds and due to predators.

Options affected by the abiotic factors due to heat and due to water.
