which two adaptations of herbivorous enables them to digest cellulose​

Answers

Answer:

Cellulose Digestion in Herbivores

By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.

Explanation:

Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.

How does herbivorous digest cellulose​?

Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.

Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.

Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.

Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose​.

what process is responsible for the absence of glucose and amino acids in urine

Answers

Answer:

The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron

Selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.

What is selective reabsorption?

The selective reabsorption mechanism allows the absorption of different substances including glucose and amino acids in the urine.

This reabsorption occurs after filtration in the capillaries of the urinary system.

The filtration and excretion of waste substances are associated with the formation of urea.

In conclusion, selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.

Zebras (grass-eaters) are ________.

Answers

Herbivores

(Why? Grass-eaters are herbivores.)

Zebras (grass-eaters) are herbivores. Herbivores are animals that eat predominantly plant stuff as their primary food source, as the name suggests.

Animals known as herbivores, as the name implies, mostly eat plant matter as their main dietary source. They belong to a number of taxonomic groupings, including those for insects, mammals, and even certain bird species. Among the various species that make up this diverse category are well-known creatures like cows, rabbits, deer, and elephants. Herbivores' specialised adaptations to consume plant matter are among the most remarkable characteristics of this group of animals. Their digestive processes, teeth, and jaws have developed to effectively break down the fibre cellulose present in plants. For instance, the many stomach chambers found in certain herbivores like cows and sheep help with the appropriate breakdown of plant material.

Moving to the part of the animation that takes place in the nucleus, which molecule is shown as pale blue/green?

Answers

Complete question:

Visit http://www.genomicseducation.ca/animations/gene_expression.asp and  play the animation.

Moving to the part of the animation that takes place in the nucleus, which molecule is shown as pale blue/green?

Answer:

snRNA molecules

Explanation:

snRNA means small nuclear RNA. These are small RNA molecules found in the nucleus and are involved in the RNA maturation process. In association with proteins, they compose the spliceosomes. They are involved in the processing phase of preRNA, which must maturate before its exportation from the nucleus as mRNA.

preRNA molecules are the first RNA transcribed and possess long intermediate sequences called introns that do not codify proteins. On the contrary, the encoding sequences are called exons.

Introns and exons alternate in the molecule, and the limit between them is called the splice site. Depending on the extreme we are looking at, they are 5´splice site or 3´splice site. Essentially, snRNA places in these sites and connects all the exons extremes of the preRNA, splicing out the introns. They remove the sequences that are not useful during the protein synthesis. This removal occurs before the RNA leaves the nucleus. Once the introns are excised the exons join to form the unique mature mRNA. This process is known as the splicing mechanism and turns preRNA into mRNA.

From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere. Oxygen was a toxic compound to most life forms from that time period. Today, oxygen is required by all but some of the most primitive life forms. Which statement best explains how early life forms that were harmed by oxygen evolved into today's life forms that require it?


Warming temperatures allowed the colonization of land environments, where oxygen was more plentiful.


Carbon dioxide-using species all became extinct, which allowed oxygen-using life forms to flourish in shallow oceans.


Over time, many species gradually adapted to a more oxygen-rich environment, allowing them to survive in shallow water and on land.


The growth of seas allowed early species to survive by using dissolved carbon dioxide in seawater rather than using it directly from the air.

Answer:

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

Explanation

Energy can be calculated by the equation

Q = m x Cp x delta T

where

m = mass = 0.5 kg

Cp = specific heat of water = 4184 J

Delta T = 12 degrees

Multiplying all

Q = 0.5 x 4184 x 12 = 25104 Joules

Converting it to Calories

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

What is chromosome ?

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount.

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.

As the carbon moves around from sink to sink, what are some effects that could result?

Answers

Sinks of carbon dioxide can be farms grasslands or forest

The effects of carbon moving from sink to sink is that there is decrease of carbon in the atmosphere.

Carbon sinks and it's effects to the atmosphere

Carbon is one of the atmospheric elements that is being recycled in nature through a process called carbon cycle.

Carbon sink is defined as the an environment or an entity that has the ability to absorbs carbon than it can return to the atmosphere. A typical example is the green plants.

These sinks are very important in keeping the levels of carbon dioxide in the atmosphere at manageable level.

Human activity in managing farmland affects the amount of carbon dioxide removed from the atmosphere by plants.

These sinks of carbon dioxide affect the carbon cycle by decreasing the amount of carbon dioxide in the air.

Therefore, the effects of carbon moving from sink to sink is that there is decrease of carbon in the atmosphere.
