Occurs to maintain homeostasis may use transport proteins to move molecules

1 answer:

8 0

Transport proteins aid the movement of these substances into and out of the cell. One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances.

What chemical reactions do monomers of lipids go through to form lipids?

Dmitrij [34]

Cellulose is one of the most abundant natural biopolymers. The cell walls of plants are mostly made of cellulose, which provides structural support to the cell. Wood and paper are mostly cellulosic in nature. Cellulose is made up of glucose monomers that are linked by bonds between particular carbon atoms in the glucose molecule.
Every other glucose monomer in cellulose is flipped over and packed tightly as extended long chains. This gives cellulose its rigidity and high tensile strength—which is so important to plant cells. Cellulose passing through our digestive system is called dietary fiber. While the glucose-glucose bonds in cellulose cannot be broken down by human digestive enzymes, herbivores such as cows, buffalos, and horses are able to digest grass that is rich in cellulose and use it as a food source. In these animals, certain species of bacteria reside in the rumen (part of the digestive system of herbivores) and secrete the enzyme cellulase. The appendix also contains bacteria that break down cellulose, giving it an important role in the digestive systems of ruminants. Cellulases can break down cellulose into glucose monomers that can be used as an energy source by the animal.

Answer: First, the bacteria will adjust and then it will divide.

Explanation:

Once the bacterial species is put into the cultural medium, there the bacteria present in the medium needs to acclimatize in the medium and then start growing.

There is a lag phase before the log phase because first the bacteria will adjust into the medium and then start dividing.

As we know that the growing medium contains amino acids, growth factors, enzymes and many more things which first needs to be utilized by the bacteria and then it will start dividing.

Which role do ultrafine particles play in dirty air?

topjm [15]

Answer:

They can worsen symptoms for people with breathing difficulties.

Explanation:

Ultrafine particles are small particles found in dirty air. They aren’t filtered due to their very small size. They enter the lungs and cause certain conditions such as oxidative stress, inflammatory mediator release, and could induce heart disease, lung disease and other systemic effects.

People who have breathing difficulties have their case worsened due to these particles.

Finger [1]

Answer: Human classification levels for order, suborder, family, tribe, genus and species are;

Primates, Primates, Haplorhini, Hominidae, Hominini, Homo, and sapiens , Hominidae, Hominini, Homo, and sapiens

Explanation:

Human taxonomy is the systematic classification of humans.

The order is primates include placenta animals including humans, that have good eyesight, flexible hands and feet, well developed brain and they include man, lemurs, apes e.t.c.

Suborder Haplorhini have a plate which cause a separation between the temporal fossa and eye socket.

Family Hominidae include group of animals that have well developed forearms and flattened digits nails.

Humans are called homo sapiens which means wise man. It is a Latin word...

Homo means man and sapiens means wise.
