Answer:
under
Explanation:
To accurately test for a slow heart rate, a person must measure their resting heart rate. To achieve this, they must avoid checking the pulse shortly after exercising or waking up.
To check the pulseTrusted Source, a person should sit in a comfortable and relaxed position and feel for the pulse at the wrist. If unable to locate the pulse at the wrist, they should try feeling for the pulse on the side of their neck.
To work out their heart rate, the person counts heartbeats for 10 seconds, then multiplies the number by six. For a more accurate pulse, the person can count the number of beats for a full minute. This figure is the resting pulse.
If the number is lower than 60, a person has bradycardia.

they needed less skin surface area touching the cold and more wider body shape so that it can keep warm its body, like how fat people are basically insulated and have a coat around their organs
Answer:
2. because they migrated to Europe with a colder climate
Explanation:
erectus populations lived in southeastern Europe by 1.8 million years ago. Neanderthal populations date back at least as far as 400,000 years ago in the Atapuerca Mountains, Spain.
As the carbon moves around from sink to sink, what are some effects that could result?
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 atmosphereCarbon 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.

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.
Note: In the attached files, you will find some fragments of the animation with the respective labels.

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.

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

Emphysema is a disease that damages alveoli describe how this disease would affect a persons ability to breathe then explain how emphysema would affect the concentration of oxygen and carbon dioxide in the bloodstream
Answer:
Emphysema is one of the lung disorders caused by damage to the air sacs in the lungs, which reduces the body's ability to take advantage of oxygen from the air. This results in inefficient breathing, because it takes extra effort to empty the air from the lungs. This disease progressively destroys the fibers that allow the airways to remain open. This problem causes the collapse of these pathways when a person exhales air. That is, the air that the lungs expel that contains carbon dioxide cannot get out, and consequently, the fresh, oxygen-filled air does not enter the lungs.
Explanation:
When we breathe, the air comes through the bronchial tree to a kind of small sacs called alveoli, which are located at the end of the bronchi and fill the lungs. From the lungs, oxygen is transported, through the arteries, to the different tissues and organs of the body. But, generally due to smoking, people with emphysema have damaged alveoli: the inner walls of these sacs weaken and break, which creates larger air spaces and therefore reduces the air exchange surface of the cells lungs. Consequently, the amount of oxygen that reaches the blood decreases and this can produce in the patient a sensation of shortness of breath, which is the frequent characteristic manifestation of this respiratory pathology. In the pulmonary alveoli, the oxygen in the air is exchanged for carbon dioxide in the blood. The walls of the air sacs are thin and fragile, so the injuries that occur in these air sacs are irreversible. Emphysema causes the alveoli - the small air sacs in the lungs that provide oxygen to the bloodstream - to weaken and they become less elastic. That means the body has difficulty getting enough oxygen or has excess carbon dioxide in the body.

My answer is down below. Don't directly copy because you will get plagiarism, and that's not what I want to happen to you. The only reason why I posted my answer is if you are in need of some help to think of things to write. Hope you enjoy it!
Explanation:
One of the sad things about this disease is that we currently do not have a cure for it. Which is very unfortunate for the people that end up getting it. There is some hope of relieving some pain, but there isn't a 100% cure. What emphysema does is it destroys the walls between your alveoli. What happens to your lungs? Well, it makes the lungs less able to absorb oxygen into our bloodstream and also remove carbon dioxide from our blood. The good news/bad news is that if you are diagnosed with emphysema you are likely to still live anywhere from 1-5 more years, which is pretty amazing that our body can last that long with damaged lungs.

Zebras (grass-eaters) are ________.
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.

which two adaptations of herbivorous enables them to digest cellulose
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.
