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.

Answers

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.

Answers

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%

Use the drop-down menus to determine which percentage is equal to each fraction.

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

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)

Answers

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.

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?

Answers

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.

How many cells does one gram of yeast contain?​

Answers

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.
