Answer:
Crossing the hygienic queen with hygienic drones.
Explanation:
For producing hygienic workers (females) in the F2 generation, the hygienic queen must be cross with hygienic drones. Due to this crossing most of the offspring produced will be hygienic due to presence of dominant allele of hygienic. Both the male and the female bees have dominant allele of hygienic so the maximum number of offspring produced will be of hygienic and very low number of offspring is produced having unhygienic allele.

What are air masses, and how do they work? Don't copy and paste.
What are Air Masses: They large volumes of air that have generally the same temperature and pressure.
How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.
Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.
Fact: Unstable air masses have different temperatures and pressures.
How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.
*** The Earth's major air masses originate in polar or subtropical latitudes.

Why do organisms compete for food and water?
Answer:
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).

1. Isoamyl acetate, sometimes
popularly called "banana oil" is
one of the compounds responsible
for banana flavor. If an enzyme
called "bananase" makes Isoamy!
acetate from isoamyl alcohol,
could you make a strawberry taste
like a banana by putting the DNA
segment for the enzyme
"bananase" into a strawberry?
Answer:
The correct answer is - no, you can not make a strawberry taste like a banana by putting the DNA segment for the enzyme "bananase" into a strawberry.
Explanation:
Enzymes are highly specific and they catalyze a particular reaction by making enzyme-substrate complex. In this case, Bananase also forms an enzyme-substrate complex with isoamyl alcohol substrate to convert into isoamyl acetate.
in strawberry the particular substrate isoamyl alcohol is not present and the other substrate that are present such as citric acid or malic acid can not bind to enzyme to convert into isoamyl acetate

Cuál es el órgano más grande del cuerpo humano
Answer:
Explanation:
La piel
Answer:
The skin is often known as the largest organ of the human body. This applies to the exterior surface, as it covers the body, appearing to have the largest surface area of all the organs. Moreover, it applies to weight, as it weighs more than any single internal organ, accounting for about 15 percent of body weight.
Explanation:
A group of biologists working in Africa observed that some of the Acacia trees growing in their study plots had clearings around them, so that no other vegetation grew within a few meters around each tree. These trees were also covered with ants. The researchers hypothesized that the ants must have cleared the vegetation around each tree. To test this, the researchers decided to remove the ants from some of the trees by spraying with an insecticide and see if vegetation grow in the clearings with the ants gone. They located 100 Acacia trees with clearings and ants present, and sprayed half of them with insecticide. The trees tended to exist in two general habitats: the first habitat was much higher in elevation and was moisture, cooler, and had more wind exposure than the second habitat. Because the insecticide spray would have drifted in the windy conditions of the higher elevation habitat, the researchers only sprayed trees in the low elevation habitat. They visited their research location once a month for two years to record whether vegetation re-grew in the clearings. Which element of experimental design is missing or flawed in this experiment
Answer:
The project showed no control over the confounding variable.
Explanation:
The confounding variable are variables that can influence the dependent variables and that were not established by the researchers. These variables exist naturally in the experiment and are able to alter the result of the experiment in a very intense way.
The dependent variable, in the case presented in the question above, is the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment. As we can see these two variables are being controlled by the researchers, however, the confounding variables such as soil fertility, water availability, sunlight intensity, wind intensity, are not being controlled and this can severely damage the experiment.
The element of experimental design that is missing or flawed is that the experiment did not control any confounding variable.
CONFOUNDING VARIABLE:A confounding variable in an experiment is a variable that can influence the outcome of the dependent and independent variables.
In this experiment, the dependent variable is case the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment.

The fossil record indicates that the earliest prehistoric birds emerged during the Jurassic period. All modern birds have evolved from these early, reptile-like birds.
Based on their common ancestry, which of the following is most likely true about modern birds?
A.
Modern bird species cannot undergo evolutionary changes.
B.
Modern bird species share many genetic similarities.
C.
Modern bird species are all genetically identical.
D.
Modern bird species do not share any genetic similarities.
Answer: B. Modern bird species share many genetic similarities.
Explanation:
When organisms are said to have a common ancestor, it means that they share many genetic similarities but are not identical due to evolution and cross-breeding. For instance, siblings may have the same parents but they will not be genetically identical even though they have a lot of similar traits owning to their parents have different traits.
The same is true for birds. They share the genetic characteristics of their common ancestor but as time went on and evolution took place, they changed in some ways and so are no longer genetically identical.
Which of the following terms best describes a lifestyle that promotes
gradual usage and replenishment of resources?
A Unsustainability
B Footprints
C Ecology
D Sustainability
D: Sustainability hope it helps
The best term that describes a lifestyle that promotes gradual usage and replenishment of resources is D : Sustainability
Sustainability in the general term is simply the ability to achieve a level of stability of resources over a very long period of time without depletion of natural resources. and to achieve this one has to ensure a consistent/gradual replenishment of used resources. while Unsustainability is the opposite of sustainability.
Other options do not comprehensively promote the gradual usage and replenishment of resources
Hence the term that best describes a lifestyle that promotes gradual usage and replenishment is Sustainability.

In which step of protein synthesis does the rRNA make protein?
Answer:
Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.
Explanation:
Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Answer D. Scratching it with other materials
Explanation:
Let's start eliminating some answers
Answer A; If you hit an object with a hammer, you will just figure out if that object can be broken with a certain amount of force. In most cases, this will not be helpful.
Answer B; When putting a material in an acid, many things could happen. This things that happen are called chemical reactions. Not every material will have a chemical reaction so this step could be useless.
Answer C; Chipping a piece off of a material will not grant you much information. Yes if may be easier to experiment will a smaller piece but the action by it's self is not useful.
Answer D; Scratching a material will another material can be very helpful. If you have two materials, labeled A and B, you can find out the Mohs hardness scale. If A is damaged by B, the hardness of A is less than B and vise versa. This can be very helpful when identifying materials.
So answer D makes the most sense
