When purchasing spread you should avoid margarine which is made from partially hydrogenated vegetable oils, which help to avoid trans fatty acids.
What are trans fatty acids?Consuming trans-fatty acids increase blood LDL cholesterol and lower HDL cholesterol, which is bad for the heart and arteries. It could also make tissue inflammation worse.
Trans-fatty acids are synthetic fats produced during the hydrogenation process, which are used to stabilize polyunsaturated oils and keep them solid at room temperature by preventing rancidity.
They might be particularly harmful to heart health and could increase the chance of developing some malignancies.
Therefore for avoiding trans fatty acids do not purchase margarine made up of hydrogenated vegetable oils.

Which statement describes the importance of the nitrogen cycle to living things check all that apply
Answers are: b) It help cells make protein ; c) It provides a form of usable nitrogen.
Nitrogen cycle is important for all living things as nitrogen is an important constituents of amino acids which makes protein, nucleic acids such as DNA and RNA, ATP and other compounds which are essential for life. During Nitrogen cycle, nitrogen is fixed into ammonia by bacteria. Ammonia is converted into nitrite and then to nitrate. Nitrate is the most usable form of nitrogen by plants. Animals feed on plants to get nitrogen. After death of plants and animals, they decomposed by bacteria and nitrogen is cycled back to atmosphere.

A ___ emits light and a ___ reflects light.
a. planet, star
b. star, sun
c. moon, planet
d. star, planet
Final answer:
The correct answer is d. star, planet. A star emits light through nuclear fusion, while a planet reflects light from a star. When light from a star passes through interstellar gas or is reflected by dust, its spectrum shows absorption lines and intensity reductions.
Explanation:
A star emits light from its core due to nuclear fusion, while a planet reflects light from a star such as the Sun. Therefore, the correct answer to the fill-in-the-blank question 'A ___ emits light and a ___ reflects light' is d. star, planet.
When observing a star, if the light emission is unobstructed, an observer would see light directly from the star. However, if the light emission is obstructed by a cloud of hydrogen gas, the observations would differ in that some frequencies will be absorbed from the spectrum (option c), causing the observed light to have dark lines or bands where the gas has absorbed specific frequencies.
Discussing the spectrum of starlight reflected by dust compared to a star observed behind invisible interstellar gas, the spectra would show intensity reductions in light and possibly absorption lines due to the materials between the star and the observer.
The lensing effect of gravity on light, as observed by the Hubble Space Telescope, reveals that stars glow by nuclear fusion while planets, which do not have fusion, are typically seen by the light they reflect.

What is the importance DNA in the human body
Apply: suppose you wanted a protein that consists of the amino acid sequence methionine, asparagine, valine, and histidine. give an mrna sequence that would code for this protein.
A possible messenger RNA (mRNA) sequence capable of encoding this protein sequence would be AUGAAUGUUCAU.
During gene transcription, a gen nucleotide DNA sequence is used as a template to create a complementary mRNA nucleotide sequence, which is subsequently used to create a protein sequence by a process called translation.
During translation, triplets of nucleotides or codons in the mRNA sequence determine specific amino acids.
The genetic code is said to be 'redundant' because different codons can encode the same amino acid residue.
For example, Valine is an amino acid that can be encoded by four different codons (GUU, GUC, GUA and GUG).
In the example above:
The codon AUG (first codon) encodes methionine amino acids. The codon AAU (second codon) encodes asparagine amino acids. The codon GUU (third codon) encodes valine amino acids.The codon CAU (fourth codon) encodes histidine amino acids.Learn more in:

Explain two ways that the heart can overcome excessive vagal stimulation
The heart can overcome excessive vagal stimulation primarily through sympathetic stimulation and response to stimuli such as blood loss. The sympathetic stimulation, driven by the cardioaccelerator regions, stimulates the release of certain compounds that increase the metabolic rate and contraction force of the heart. In response to stimuli like blood loss, the heart rate increases and blood pressure rises, offsetting the excessive vagal stimulation.
Explanation:The heart, when facing excessive vagal stimulation, can counterbalance it primarily in two ways, which are centralized in the cardiovascular centers of the medulla oblongata.
First, sympathetic stimulation can overcome excessive vagal stimulation. The cardioaccelerator regions within the cardiovascular centers drive this sympathetic stimulation via the cardioaccelerator nerves. This stimulation has a stimulatory effect on the heart: it triggers the release of norepinephrine (NE) at the neuromuscular junction from the cardiac nerves and also encourages the adrenal cortex to secrete epinephrine and NE. These compounds bind to alpha and beta receptors on the cardiac muscle cell membrane, increasing the metabolic rate and the force of contraction, thereby escalating the stroke volume (SV) and heart rate (HR).
Secondly, in response to stimuli such as blood loss, baroreceptors trigger the cardiovascular centers to stimulate sympathetic responses to increase cardiac output and vasoconstriction. This mechanism prompts the heart rate to increase and consequently increases blood pressure, managing to override the excessive vagal (parasympathetic) stimulation.

The earth is estimated to be about 4.5 billion years old. Rocks and rock formations found throughout earth’s crust give scientists clues to the past. They assume that the processes that acted on the crust millions of years ago are the same processes that act on and within earth today. This is called the principle of uniformity or uniformitarianism.
The law of superposition helps us infer the age of rock layers, or strata. This law states that, if layers of rock are left undisturbed, the layers at the bottom are the oldest. The lower layers must be in place before younger layers can be deposited on top of them. Scientists infer the relative age of the layers as well as any fossils found within them. The law of superposition does have exceptions. Some processes within the earth cause younger layers to be moved below older. Folding, faulting, and intrusion can cause these exceptions. Regardless of position, any rock is always older than the process that changed it.
Geologist infer that the fossils number 3 and 5 are approximately the same age. This assumption of relative age is based on what information from the passage?
Answer:
It is based on the law of superposition to infer the age of rock layers and there by determining the age of fossils present in it.
Explanation:
From the passage, the law of superposition states that lower is the layer of rock, older is its age. We can determine the relative age of rock layers with the help of this law, if the the rock layers are not disturbed during the course of time.
Since fossils can be observed in these rock layers we can use the technique of relative dating to determine the relative age of fossils. In this method, we can reasonably say that the fossils found closer to the surface of earth are the more recent ones than the fossils found in the deeper layers of rock.
Fossils found in the same layer of rock can be supposed to be of same age. This relative dating method is useful to compare the ages of fossils but we cannot precisely find it.
