The purpose of the respiratory system in the body is filters air and brings oxygen into the body.

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism.

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system.

Answer:

What is the order that waste travels through the urinary system?

kidneys: two bean-shaped organs that filter waste from the blood and produce urine. ureters: two thin tubes that take pee from the kidney to the bladder. bladder: a sac that holds pee until it's time to go to the bathroom. urethra: the tube that carries urine from the bladder out of the body when you pee.

Answer:

red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies

Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.

All cells in the body essentially have the same genome except some red blood cells and some immune cells.

Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.

Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

option B

Explanation:

Answer:

Explanation:

Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.

Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.

It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?

Living beings are organisms that can respire, respond, grow, reproduce, and are made of cells. All living things have a genetic code. Thus, option B is correct.

A genetic code is a sequence of proteins and nucleic acids that act as a hereditary molecule that transfers the traits and characteristics to the progeny.

The code can be in the form of DNA or RNA and provides information about the genotype of the organisms that were passed from their ancestors.

The genetic code is in the form of triplets and is a universal system that codes for the same proteins in all organisms. It consists of the nitrogenous bases that through translation make the amino acids.

Therefore, option B. all living organisms have a genetic code.

CAN I GET BRAINLIEST

Answer:

No, because Pneumonia can be transferred from one person to another.

Explanation:

Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.

Answer:

Sunlight and water.

Explanation:

The sun is the plant's most important nutrient. Plants convert sunlight into sugars in order to grow. Water is needed in two ways, it serves as both a solvent for mineral salts that are carried inside plant cells, and it is an essential component of photosynthesis. The questioner might have asked "name one" so they don't have enough information to answer with any greater certainty - but the answer remains the same regardless of how many nutrients they ask about.

Minerals are also required by plants in order to function properly including calcium, potassium, iron, magnesium just to name a few minerals which are found in healthy nutritious produce!

Answer:

Animals such as rhinos, dolphins, and more.

Explanation:

Answer:

animals, plants, humans and much more.

Explanation:

Answer:

In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.

The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.

Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.

This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.

Eukaryotes that are not fungi, animals, or plants are called protists

Protists can be described as eukaryotes that are not grouped as fungi, animals or plants. These groups of organisms are so wide that there are lots of organisms that fall under this category.

Protists are tiny group of organisms that can only be seen/viewed with the aid of a strong microscope. Protists only have one type of cell and lots of these organisms are found in an aquatic environment.
