Answer:
If a food has less than 0.5 grams of saturated fat in the serving size on the label, the food maker can say it contains no saturated fat. Remember this if you eat more than 1 serving. You should also pay attention to trans fats on any food label. These fats raise "bad" cholesterol and lower your "good" cholesterol.

The complete chart indicating the number of chromosomes after meiosis, in body cells, in gametes and after mitosis are indicated in the given image.
Meiosis is the process of cell division in which the number of chromosomes are reduced to half. This is the reason why it is also called the reductional division. The process occurs in two phases: Meiosis I and Meiosis II. Meiosis I is the phase where actual reduction takes place.
Mitosis is the process of cell division where the daughter cells are identical to the parent cell. Here, the number of chromosomes remain the same and hence is called equational division.

sodium and potassium ions are transported against their concentration gradients.
the cell is not expending energy.
sodium ions are transported down their concentration gradient.
potassium ions are transported down their concentration gradient. the cell does not expend atp?
Option A. Both sodium and potassium ions are transported against their concentration gradient.
A concentration gradient happens when the attention of particles is better in a single area than in every other. In passive shipping, particles will diffuse down a concentration gradient, from areas of better awareness to areas of decreased concentration, until they are frivolously spaced.
A concentration gradient happens when the concentration of debris is higher in a single vicinity than in some other. In passive transport, debris will diffuse down a concentration gradient, from areas of higher awareness to areas of decreased awareness, till they're frivolously spaced.

According to the given statement The average atomic mass of rubidium is 85.468 .
What is atomic mass?The average mass of an element's atoms measured in atomic mass units is known as its atomic mass (amu, also known as daltons, D). The mass of each isotope is divided by its abundance to create the atomic mass, which is a weighted average of all the atoms of that material.
Briefing:Given that the abundance of the ⁸⁵Rb isotope is 72.17% and its atomic mass is 84.912amu
We get 84.912 x 0.7217 = 61.281
And the abundance of the isotope ⁸⁷Rb, having an atomic mass of 86.909, is 27.83%.
We get 86.909 x 0.2783 = 24.187
Thus we get 61.281 + 24.187 = 85.468 as the average atomic mass of Rubidium.

What does not occur as a result of loss of biodiversity? A) Increase in pest populations because of loss of predatorsB) increase in the hole in the ozoneC) impaired soil formationD) less efficient water purification
Let's define what biodiversity is:
Biodiversity if the variety of different species within an ecosystem.
Now let's apply this information to answer our question:
We are trying to find which answer choice would not result in a loss of biodiversity, aka which of the answer choices increases the biodiversity.
0. Increase in pest populations because of loss of predators - this answer choice is ,correct,. We are ,increasing, a population in the ecosystem.
,1. Increase in the hole in the ozone - this answer choice is ,incorrect,. An increase in the hole of the ozone is ,dangerous, - it kills off populations of species living within an ecosystem.
,2. Impaired soil formation - this answer choice is ,incorrect,. If soil formation is incorrect, primary producers wouldn't be able to grow, affecting populations by decreasing them within an ecosystem.
,3. Less efficient water purification - this answer choice is ,incorrect,. If there is not enough water present in an ecosystem, it will cause populations to go down, ,decreasing, the biodiversity.
Therefore, our answer choice is A.

Is the method "Reduce, Reuse, Recycle" useful in getting rid of plastic in our environment?
The method "Reduce, Reuse, Recycle"is really important for managing human impacts in our environment. The less plastic we consume (reducing), the better. As much as we can reuse the plastic, the better also. We wouldn't be creating that many trash and would be reducing pollution. Recycling is always the best way to deal with our trash, so it won't be harmful to the environment. However, to really get rid of plastic in our environment it is important to stop producing plastic as well, not only reducing the consume, reusing the plastic and recycling the trash

What material is left over in thelarge intestine?A. insoluble fibers, waste, and waterB. the liquefied food full of nutrients to be absorbed into the blood streamC. a ball of food waiting to be broken downD. small pieces of food mixed with enzymes and digestive substances
The goal of the large intestine is to absrob minerals, remaining nutrients, and specially water. So this kind of components must enter the large intestine. Therefore the correct option is A. "Insoluble fibers, waste and water. B./C are not correct, because the food full of nutrientes/ball of food enters the small intestine, before the large one. D. is not correct either, because the food along with enzymes are the products that exit from the stomach.
People pave over a large field to build a parking Which of the following describes how this action will likely affect the water cycle for this region ?
The rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas.
What is meant by the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
Concrete is less porous than soil, thus the water won't be able to seep back into the soil. The volume of water in subsurface aquifers would decrease as a result.
Additionally, the rain will be able to run off more quickly on concrete and in a vast field, which will probably cause flooding in both areas. Both of these would probably hasten the water cycle and have detrimental consequences for people.
Therefore, the correct answer is option c. Runoff into storm drains increases.

In animals, fertilization is to zygote, as meiosis is to (5) gamete.
Fertilization is the process of fusion of the male and the female gamete in order to form new organism which is diploid in nature. This process occurs only in the sexual mode of reproduction and unlike asexual reproduction, presence of two parents is essential in this.
Gamete is the germ cell that is involved in the process of sexual reproduction, in order to give rise to a new organism. Gamete is haploid in nature because it fuses with another gamete of the opposite sex in order to establish the diploid nature.

a technologist is performing a body fluid analysis on a csf specimen recently received in the laboratory. four csf tubes were sent to the body fluids bench. the tech notices that all four specimens seem moderately blood tinged equally. moderate xanthochromia was also noted. what is the most likely reason for these findings?
The most common cause of xanthochromia, which manifests as a yellow, orange, or pink staining of the CSF, is the breakdown of haemoglobin into oxyhemoglobin, methemoglobin, and bilirubin as a result of RBC lysis.
Xanthochromic CSF: Is it typical?The yellowish staining of a centrifuged CSF specimen's supernatant is known as xanthochromia. It is abnormal and arises from the breakdown pigments oxyhemoglobin, bilirubin, and methemoglobin being released from RBC lysis into the CSF during Xanthochromia therapy. Treatment for xanthochromia entails addressing the underlying cause. If xanthochromia in the CSF indicates that the patient has a subarachnoid haemorrhage, they may have magnetic resonance imaging (MRI), CT angiography, or be sent immediately to the hospital for treatment.
A issue with the central nervous system is suggested by an abnormal protein level in the CSF. A tumour, haemorrhage, nerve irritation, or damage may all be indicated by an elevated protein level.
