Explanation:

health class and quick double check to a reliable source

The correct option is, (g) All of the above.

What are the 4 main functions of the respiratory system?Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.

What describes the function of the respiratory system?We can breathe thanks to our respiratory system and lungs. They expel carbon dioxide and inspire oxygen into our bodies, a process known as inspiration or inhalation (called expiration, or exhalation). The process of breathing involves the exchange of oxygen and carbon dioxide.

Which of the following performs the function of respiration?The network of organs in the human respiratory system is in charge of absorbing oxygen and exhaling carbon dioxide. The lungs, which perform this gas exchange as we breathe, are its main organs. All of the body's cells are supplied with oxygen-rich blood by the circulatory system and the lungs.

The answer is 3 3 3 3

The physical properties of graphite which makes it good for pencils is ;  

( 3 ) hardness and streak

Graphite is made up of carbon atoms which are held together by van der waals forces ( weak force ). They are soft and slippery which is why graphite is used in the manufacture of  lubricants. while graphites are used for the manufacture of writing materials such as pencils because of its hardness and streak

Hence we can conclude that the physical properties of graphite which makes graphite good for the production of pencils are hardness and streak

Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.

Answers

Solution :

The flow of oxygen in the blood is been transported by two ways :

1. in plasma 1.5%

2. bound to hemoglobin 98.5%

As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.

The decreased pH weakens the hemoglobin oxygen binding in the tissues.

Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.

Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.

The enzyme lactate dehydrogenase is responsible for fermentation of pyruvate to form lactate. This process occurs in red blood cells and in muscle cells during intense exercise. Why is fermentation a necessary process for these cells to meet their energy needs

Answers

Answer:

Fermentation is a process that happens in the absence of oxygen and it involves the conversion of Pyruvate to lactate.

Cells in the body need constant energy supply to cater for the various demands of our everyday activities and to ensure that they function optimally.

Oxygen supply is an important factor in ATP generation and in cases where there is a lack of it the body system adjusts itself to produce the energy anaerobically. This usually involves the conversion of pyruvate to lactate which aids the breakdown of glucose thereby supplying it to cells of the body.

Answers

Answer:

Mitosis:

A single division occurs, separating sister chromatids

End result is two diploid cells that are genetically identical to each other and the parent cell

Meiosis:

The first division separates homologous pairs; the second division separates sister chromatids

Homologous chromosomes pair up and form chiasmata

Homologous pairs of chromosomes line up on the metaphase plate

Daughter cells contain recombinant chromosomes

End result is four haploid cells that are genetically different from each other and the parent cell  

Mitosis and Meiosis:

Chromosomes duplicate during interphase

Process starts with a diploid cell

Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell

Explanation:

Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.

A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.  

Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis.  During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.

Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.

Answers

Answer:

ventilation

Explanation:

Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.

What is the heterozygous ?

The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism   will be i gene.

Answers

Answer:

The correct answer is ''sporophyte and a gametophyte''

Explanation:

Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

Mass of the moon is 7.4x10^22 kg and its radius is 1740km, Calculate the value of acceleration due to gravity on the surface of the moon. *​

Answers

Answer:

The gravitational acceleration in the surface of the moon is 1.63 m/s^2

Explanation:

The gravitational acceleration at a distance R of an object of mass M, is given by:

g = G*M/R^2

Where:

G is the gravitational constant.

G = 6.67*10^(-11) m^3/(kg*s^2)

We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:

R = 1740km

But we want to work with meters, so remember that:

1km = 1000m

then:

1740km = (1740)*1000m = 1740000m

R =  1740000m

And the mass is just:

M = 7.4x10^22 kg

If we input all that in the gravitational acceleration equation, we get:

g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2

g = 1.63 m/s^2

The gravitational acceleration in the surface of the moon is 1.63 m/s^2
