Describe how enzymes affect chemical reactions and explain why this makes enzymes important to living thing.

Answers

Enzymes boost the speed of chemical reactions.

They are very important because in absence of that, process of digestion would take place in several months.....

Enzymes speed up reactions such as digestion. Without them, we'd take weeks to digest our food, which means we wouldn't be able to survive.

Which sequence represents a cross section of the bilayer

Answers

hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head

Answer:

The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.

A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.

The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.  

Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

Which organisms are prokaryotes?

Answers

Prokaryotes are single cell organisms. They do not have a membrane-bound nucleus or any mitochondria. Archaea and bacteria are the two domains of prokaryotes. For example, cholera and anthrax are two pathogenic bacteria.

Final answer:

Prokaryotes are single-celled organisms lacking a nucleus and membrane-bound organelles. Bacteria and Archaea are the two domains of prokaryotes. They are abundant, versatile, and found in a wide range of environments. Prokaryotes serve various functions and impact the health of ecosystems.

Explanation:

Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. The two prokaryotic organisms are Bacteria and Archaea. They are abundant and found in diverse environments, from extreme conditions like boiling springs and frozen environments in Antarctica, to more moderate conditions like the human digestive system. Prokaryotes play important roles in various ecosystems and are responsible for certain illnesses.

Explanation:

Bees use nectar from the flowers of plants as food. As they collect nectar, dustlike pollen grains stick to their body. When they move from flower to flower, pollen is transferred to other flowers. The pollen from other flowers helps the plant make seeds. Which challenge of life does the bee help the plant meet?a. acquiring energy
b. reproduction
c. maintaining its structure
d. homeostasis

Answers

Reproduction is the challenge of life that the bees help the plant to meet. The correct option in regards to the given question is option "b". This process is also known as mutualism. In this case both the flowers and the bees are mutually helping each other. The bees get the food from the nectar produced by the flowers and in turn the bees help the species of plants to reproduce. This is a natural way of being beneficial to one another.
b. reproduction, by collecting the pollen the bees r also spreading the pollen

Which of the following would not be a contributing factor to the life span of goldfish in a backyard pond?a. the pH level of the pond water.
b. the size of the goldfish
c. the food source availability in the pond
d. the temperature of the pond water

Answers

The option that would not be a contributing factor to the life span of goldfish in a backyard pond is B. the size of the goldfish. I don't see how their size would affect the life span of a fish, whereas the pH levels, the food availability, as well as the water temperature can either increase or decrease how much these fish can live.
b. the size of the gold fish
