How many cells does one gram of yeast contain?
Answer:
20 billion cells
Explanation:
It is based on the assumption that there are 20 billion viable yeast cells per gram of dried yeast. While there are 20 billion cells, you'll find that many manufacturers will state other numbers on their products.
The number of cells that one gram of yeast contain is 12 billion cells.
What are yeast cells?Yeasts are found in soils and on plant surfaces all over the world, and they are particularly prevalent in sugary environments like flower nectar and fruits.
It is predicated on the idea that each gram of dry yeast contains 12 billion live yeast cells. Despite the fact that there are 12 billion cells, several manufacturers will list different quantities on their products.
As opposed to mushrooms, yeast is a fungus that develops as a single cell, according to Laura Rusche, an associate professor of biological sciences. Although there is just one cell in every yeast organism, these cells form multicellular colonies.
Therefore, Yeast has 12 billion cells per gram.

Which statement best describes why the population growth rate slows as population size approaches carrying capacity?
O reproduction increases
O predation rates decrease
evolution of traits decreases
competition for resources increases
Answer:
competition for resources increases
Explanation:
When an ecosystem reaches its carrying capacity, competition for scarce resources become more intense.
The result of this is that species will either begin to die, or migrate away from the ecosystem leading to a decrease in population growth

Based on the description of DNA, given in the Do Now, what could be the nucleotide composition of a DNA double helix? 90 points 20% adenine, 20% guanine, 30% thymine, 30% cytosine 60% adenine, 20% thymine, 10% guanine, 10% cytosine 20% adenine, 20% thymine, 30% guanine, 30% cytosine 60% adenine, 20% guanine, 10% thymine, 10% cytosine
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

1. Scientific question: Can detergent affect flower growth?
2. IV: The soap used in the study
3. DV: Flower growth
Explanation:
A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.

The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.
PLS HELP FAST!!!! You have a natural-gas (methane, CH4) stove. When you ignite a natural-gas stove, the methane reacts with oxygen (O2) to produce carbon dioxide and water vapor. Write a balanced equation for this reaction, and be sure to show your work. (6 points)
Answer:
Methane (CH4) ( C H 4 ) burns in oxygen to produce carbon dioxide and water vapor. The balanced equation is: CH4+2O2→CO2+2H2O C H 4 + 2 O 2 → C O 2 + 2 H 2 O .
Explanation:
The balanced equation for the reaction of methane with oxygen is CH₄ + 2O₂→CO₂ + 2H₂O.
What is methane?Methane is a gas and a chemical compound with formula CH₄. It is a colorless and odorless gas and very flammable. It is made up of carbon and hydrogen. Methane comes under greenhouse gas.
As it is highly reactive, it reacts with the gases present in the environment. Here, methane is reacting with oxygen. When one molecule of methane reacts with two molecules of oxygen, it produces carbon dioxide and two molecules of water.
The reaction happens in the presence of heat and high temperature. The balanced reaction is written when the same number of moles are present on both sides of the reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O.
Thus, the balanced equation for the reaction CH₄ + 2O₂→CO₂ + 2H₂O CH₄ + 2O₂ → CO₂ + 2H₂O.

B.Amount of carbon dioxide used by the corn plants
C.Volume of oxygen produced by the corn plants
D.Number of corn plants used
Answer: A) the air temp at which the corn plants are grown
Explanation:
The independent variable is the one that changes based on what problem/ question the experimenter is trying to solve. The student is trying to see if the air temp has an affect on the rate of photosynthesis so they whorls use various temps and measure the rate
The constant in this experiment is the number of corn plants used.
WHAT IS A CONSTANT VARIABLE:
In an experiment, a constant or control variable is a variable that is kept the same for all groups of the experiment. The independent variable is tested to bring about a change in a dependent variable in an experiment. However, every other variable of the experiment must be kept constant. These variables are called CONSTANT.In this question, the independent variable is the air temperature while the dependent variable is the rate of photosynthesis.A constant in this experiment is the number of corn plants used.

Refer to the family pedigree shown here. In generation I, one parent is affected by the gene mutation and one parent isn't. In generation II, all three children are affected by the gene mutation. What can you conclude about this gene mutation?
Answer:
What can be concluded about this genetic mutation is that it is inherited as a dominant trait.
Explanation:
In the case that one of the parents has a mutation whose inheritance pattern is dominant —which is rare— all the descendants will have the same mutation, since this gene will necessarily be expressed.
A dominant allele is one whose presence produces the phenotypic expression of the characteristic it determines. When the mutation is dominant, it will always be expressed in the descendants.
Hungtinton's disease and achondroplasia are examples of mutations with an autosomal dominant inheritance pattern.

Answer:
Carbon sinks can be natural or man-made. They absorb more carbon than they release, whereas carbon source is anything that releases more carbon than they absorb. ... Together Earth's land and Ocean sinks absorb half of the carbon dioxide emissions.
Explanation:
Humans can be considered carbon sinks - yes, for a lifetime.
living organisms are better long-term sinks than humans - plants or trees.
Carbon sinkanything that absorbs more carbon from the atmosphere than it releasesit is the opposite of a carbon source as a carbon source is anything that releases more carbon than it absorbsHumans release carbon mainly by respiration, however, absorbs very less amount as foodPlants grab carbon dioxide from the atmosphere to use in photosynthesis and only some of this carbon is released to the soil when plants die and decomposeLearn more:

With statement best describes the anther in a flowering plant? A. It is the colored part of the flower that attracts pollinaters. B. It is the part of the stem that supports the weight of the plant. C. It is the part of the stamen that contains the pollen. C. It is the part of the flower that contains the eggs.
Answer: C. It is the part of the stamen that contains the pollen
Explanation:
Anthers are the pollen containing units in a flower that can be found in the stamens of such flowers. It should be noted that typically, anthers consist of two parts which are referred to as the thecae and each one of the theca is made up of two microsporangia.
Therefore, from the explanation above, we can infer that the another is the part of the stamen that contains the pollen.
