called CF is a condition that causes excess mucus production in the lungs and if untreated causes early death. CF is caused by a deletion of 3 letters in the gene sequence. How might this deletion cause excessive mucus production?

Answers

Answer:

The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.

Answers

For the first half of your question, plants do need to eat. In fact, they are autotrophs, which means they are self feeders.

Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

What are Autotrophs?

Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.

The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.

Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.

Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.

Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

Eukaryotic organisms are fungi, plants, and animals. Thus, the correct options are B, C, and E.

What are Eukaryotic organisms?

Eukaryotic organisms may be defined as those organisms whose cells have a well-defined nucleus and the existence of membrane-bound cell organelles. They are single-celled or multicellular in nature. They belong to the group of organisms Eukaryota or Eukarya.

There is a large range of eukaryotic organisms in nature. Examples of eukaryotic organisms are all animals, plants, fungi, protists, and most algae. While bacteria are classified into the category of prokaryotic organisms.

Viruses are neither eukaryotic nor prokaryotic in nature. This is because they are non-cellular and can not able to multiply or reproduce outside the living host.

Therefore, eukaryotic organisms are fungi, plants, and animals. Thus, the correct options are B, C, and E.

Which of the following is not an example of mutualism?


Plsss help

Answers

Answer:

D. Conifers and Grasses spreading their pollen with the wind.

Explanation:

Let's start with what mutualism is. Mutualism is when both parties of a relationship benefits. So, when you go to the doctor, this would be mutualism. The doctor is getting paid, and you are getting healthy. Both sides benefit!

Now let's go thrugh out examples.

Moths drinking nectar and pollinating night blossoming flowers: The moths get fed (nectar), and the plants get pollinated (their whole purpose). Both sides benefit.

Bees drinking nectar and pollinating many angiosperms of food supply: This option might seem confusing because of the term angiosperm. I promise it isn't! Ignore angiosperm. Bees are drinking nectar -> they benefit. The other thing is getting pollinated. All plants like getting pollinated, no matter their fancy name. So both sides benefit!

Beekeepers maintaining colonies of bees and moving them to different farms and orchards: This one might also have been hard, because it requires sme critical thinking. Let's look at the beekeepers first. Beekeepers make money off of honey when they have bees, so they benefit. But do bees benefit in this relationship? Yes! Bees like having lots of plants to pick from to get their pollen. By being moved to an area with lots of plants, they get more pollen, so they benefit!

Now, we know the last one HAS to be right. But let's go through it anyways.

Conifers and Grasses spreading their pollen with the wind: Right away we know the conifers and grasses are benefitting. They want to spread their pollen- why else would they do it? But, to be mutualism, another party has to be benefitting. In this equation, there is no other party. Maybe you thought the win, or maybe you thought of the fields. What are they getting out of this relationship? Nothing. This is not mutualism.

Hope this helps and feel free to ask for any more clarification!

because males are XY and females are XX, if two people have a son, he will receive a Y chromosome from his father and an X chromosome from his mother, if one of her alleles is recessive color blindness, there is a chance he could be color blind.
