You have a 2 gram/mL stock solution of protein. To make 10 mL of 1 mg/mL solution, add 0.05 mL of stock and 24.95 mL of water for a final volume of 25 mL.
What are measurements?In this case, the new solution is expressed in milligrams per mL (mg/mL) while the stock solution is expressed in grams per mL. Let's only utilize mg/mL for the computations.
By assuming that the amount of protein in the new solution is equal to the amount we would remove from the stock solution, we can obtain an equation.
Therefore, you have a 2 gram/mL stock solution of protein. To make 10 mL of 1 mg/mL solution, add 0.05 mL of stock and 24.95 mL of water for a final volume of 25 mL.

A. The calcaneus is __ to the toes
B. The scapula is __ to the sternum
The words that best complete the sentences are:
A. The calcaneus is proximal to the toes.B. The scapula is distal to the sternum.What is the Proximal?A. Proximal refers to a body part being closer to the center of the body, or closer to the point of attachment to the trunk of the body. The calcaneus, or heel bone, is proximal to the toes because it is located closer to the body and nearer to the point of attachment to the lower leg bones.
B. Distal refers to a body part being farther away from the center of the body, or farther away from the point of attachment to the trunk of the body. The scapula, or shoulder blade, is distal to the sternum, or breastbone, because it is located farther away from the center of the body and farther away from the point of attachment to the clavicle (collarbone).

Explanation:
You are standing in a location that is clear in the morning, but in the afternoon there are thunderstorms. There is no wind during the day, so the thunderstorms build directly above you. Describe how this happens.
The formation of the thunderstorms occurs as follows:
layers of warm, moist air travel quickly to cooler areas of the atmosphere in a massive updraft, which is how thunderstorms form. Tall cumulonimbus clouds and subsequently precipitation are created there as a result of the moisture in the updraft condensing.What are thunderstorms?A thunderstorm, also known as an electrical storm or a lightning storm, is a type of storm in which lightning is present and produces the audible sound of thunder in the atmosphere of the Earth.
Because the land warms up during the day and rises in the afternoon, hot, moist air rises until it reaches a certain height before condensing, which is when ordinary cell thunderstorms most usually form.

How is dsRNA different in function from other types of RNA?
Responses
It contains thymine instead of uracil.
It's used in transcription instead of translation.
It's single-stranded instead of double-stranded.
It destroys mRNA instead of making proteins.
The viral RNA, dsRNA, blocks the expression of certain genes by degrading mRNA molecules. Option D. It destroys mRNA instead of making proteins.
What is dsRNA?
dsRNA is a viral bi-catenary RNA. It is a double-stranded molecule (double-strand, ds).
dsRNA is capable of silencing specific sequences of certain genes. The dicer enzyme cuts dsRNA molecules and produces siRNA small interfering RNA).
siRNAs suppress the expression of target genes when cutting messenger RNA into two halves.
The two mRNA halves are later degraded by the cellular machinery, leading to the suppression of gene expression.

if an organism has a high biological fitness in one habitat does it mean it will also have a high biological fitness in a different habitat?
Answer:
No
Explanation:
Biological fitness does not necessarily means the most built organism rocking the 6 pack abs :) it usually means someone who is able to survive and give rise to lots of offspring in a given environment.
A shark has high biological fitness in the ocean but it won't do it any good if we put the shark in land. Thus, fitness comes from adaptation of organism to the environment and will change if we change the environment.
Shark's traits are useless in land thus it wont be "fit" for the new environment. Thus, high fitness in one place does not necessarily guarantee fitness in all different environments.

Click on three details that best explain why some people support GMOs
GMOS are organisms that have been artificially modified to produce new or altered characteristic. These organisms are modified by
scientists in a laboratory. The method involves altering the genetic code of plants and animals to produce desired traits. Most of the crops
in the United States, including wheat and corn, have been genetically modified.
Supporters of GMOs include large corporations and the Food and Drug Administration (FDA), a government agency responsible for
monitoring food safety. Crops made from GMOs produce large quantities of food. Supporters of GMOs cite that there needs to be more
food to keep up with the growing population. However, corporations also want to sell their products and increase profits. They support
GMOs because there is a lot of money to be made from selling engineered food.
GMO supporters state that genetically modified foods are safe and do not pose health risks. However, there have not been enough
studies to prove these claims. The fact is that most crops are sprayed with toxic chemicals to protect them from bugs and pests.
Genetically modified organisms are designed to resist pesticides, so the chemicals do not affect the plant. However, the concern is that
these chemicals are causing health problems in humans. For this reason, many countries have banned the use of GMOS.

A table compares the products and reactants of processes. For which process would water be listed as a product?
A. chloroplasts
B. photosynthesis
C. ATP
D. cellular respiration
Through cellular respiration, the cell can use organic compunds and turn them into CO2 and water, releasing several ATP molecules. Option D. Cellular respiration.
What is cellular respiration?
Cellular respiration is the process through which cells produce energy as ATP for the organism to accomplish its functions.
Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic respiration occurs in the presence of free oxygen. It needs the organic compounds to obtain chemical energy, and involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.
Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.
Aerobic Respiration's final products are CO₂, ATP, and water.
According to this framework, the correct option is D. Cellular respiration.

To measure primary production of algae in a lake, you place two sealed chambers in the lake, each
enclosing the sediments as well as the water above them. One chamber is covered with black tape
(blocking all light) while the other is transparent to light.
You measure dissolved oxygen (DO) before and after a 24-hour incubation. DO in the light chamber
increased by 2.25 g/m² while DO in the dark chamber decreased by 1.5 g/m².
Remember, GPP = NEP + Re.
You are given two of these values above!
What is the estimated gross primary production (GPP) for the lake? Remember, GPP = NEP+ Re.
Gross primary production (GPP) measures how much chemical energy is produced from light energy in a specific amount of time.
What is primary production in a lake?LAKES AND RESERVOIRS ARE USED FOR PRIMARY PRODUCTION. Planktonic algae (phytoplankton), periphytic algae (periphyton), and macrophytes are the three main types of primary producers found in both natural and artificial lakes (larger rooted aquatic plants).The units are mass, area, and time, with the mass of carbon per square metre per year (g C m2 yr1) being the most prevalent.Radioactive bicarbonate is used as a tracer of carbon (C) uptake by autotrophs in the most popular technique to evaluate primary production in lakes (Nielsen 1952).Gross primary production (GPP) measures how much energy the sun can provide to plants (GPP). The mass of carbon that a plant absorbs during photosynthesis can be measured as an indirect method of determining this.To learn more about Gross primary refer to:
