Answer:

Homozygous Dom and Homozygous recessive traits are both shown.

Look below for answer V

Explanation:

Considering that both are homozygous, that means that both traits are of the same kind.

Unattched earlobes is dominant, which means its sign would be (EE)

Attatched is the recessive, which means its sign would be (ee)

On a table, the genes would look this way-

         EE             EE

ee     Ee              Ee

ee     Ee              Ee

Since there is a dominant trait in all of the genes, the children would 100% have unattached earlobes.

(As a counter situation, if the unattatched was heterozygous, the chance of attatched to unattatched would be 50/50 as theres no dominant trait lurking)

I may be incorrect but i hope this helps!

The actual alleles that an organism possesses make up its genotype. The appearance or characteristic of an organism is known as its phenotype. A person would have detached earlobes if their genotype was Ee.

The person who has free earlobes and is heterozygous has the genotype Ee and is capable of producing both the E and e alleles.

Punnett's squares are a good illustration of this. The person who has linked earlobes has the genotype ee and is only capable of producing e alleles.

All the genes have a dominant characteristic, therefore all the offspring would have detached earlobes.

Since there is no hidden dominant characteristic, (as a counter example, if the unattached was heterozygous, the risk of attached to unattached would be 50/50)

Before filling in a Punnett square, the first thing you must determine is the gametes contributed by each parent.

A Punnett square is a visual tool used in genetics to predict the possible outcomes of a genetic cross between two individuals. It helps determine the potential genotypes and phenotypes of offspring based on the alleles contributed by each parent.

To construct a Punnett square, you need to know the possible gametes that each parent can contribute. Gametes are the reproductive cells (sperm and eggs) that contain half the genetic material of an individual. Each parent carries two alleles for a particular gene, and these alleles segregate during gamete formation.

By determining the gametes contributed by each parent, you can identify the possible combinations of alleles in the offspring. This information is crucial for filling in the Punnett square and predicting the genotypic and phenotypic ratios of the offspring.

Once the gametes are determined, they are placed in the appropriate cells of the Punnett square to represent all possible combinations. By analyzing the square, you can determine the genotypic and phenotypic ratios, which provide insights into the inheritance patterns and traits expressed in the offspring.

In summary, before filling in any Punnett square, it is essential to determine the gametes contributed by each parent, as this information forms the basis for predicting the genotypic and phenotypic ratios of the offspring.

The 3-cell model, ENSO, and the MJO are interconnected phenomena that impact each other and play crucial roles in shaping regional and global climate patterns. Topography and ocean currents are two local influences on climate that can be more influential than a location's position in the 3-cell model. ENSO and the MJO do impact hurricane activity, with El Niño and the active phase of the MJO suppressing hurricane activity, while La Niña and the inactive phase of the MJO can enhance it.

The 3-cell model, El Niño Southern Oscillation (ENSO), and the Madden-Julian Oscillation (MJO) are all related to each other and impact each other in different ways.

1. The 3-cell model refers to the global atmospheric circulation pattern that divides the Earth into three cells: the Hadley cell, the Ferrel cell, and the Polar cell. These cells are responsible for the movement of air and transfer of heat from the equator to the poles. They play a significant role in determining regional climate patterns and wind systems.

2. El Niño Southern Oscillation (ENSO) is a climate pattern that occurs in the tropical Pacific Ocean. It involves the interaction between the ocean and the atmosphere, resulting in a warming or cooling of sea surface temperatures in the eastern tropical Pacific. This phenomenon has a major impact on weather patterns worldwide, affecting rainfall distribution and temperatures.

3. The Madden-Julian Oscillation (MJO) is an eastward moving disturbance that travels around the equator. It is characterized by a large-scale, eastward-moving area of enhanced and suppressed rainfall. The MJO has a significant influence on tropical weather and can affect precipitation and atmospheric circulation patterns in various regions.

These three phenomena are related in that they all involve large-scale atmospheric and oceanic processes. For example, during an El Niño event, the warming of sea surface temperatures in the eastern tropical Pacific can disrupt the normal trade winds and atmospheric circulation patterns associated with the 3-cell model. This disruption can, in turn, affect the behavior and strength of the MJO.

b) Two local influences on climate that can be more influential than a location's position in the 3-cell model are topography and ocean currents.

Topography refers to the physical features of the land, such as mountains, valleys, and coastlines. These features can greatly influence climate by affecting the distribution of precipitation, temperature, and wind patterns. For example, mountain ranges can block the flow of air masses, leading to differences in rainfall on the windward and leeward sides.

Ocean currents play a crucial role in climate regulation. They transport heat from the tropics to higher latitudes and influence regional temperature and precipitation patterns. For instance, the Gulf Stream, a warm ocean current, influences the climate of the eastern coast of the United States, making it warmer than other regions at similar latitudes.

c) Yes, ENSO and the MJO can impact hurricane activity.

During an El Niño event, the warming of sea surface temperatures in the eastern tropical Pacific can alter atmospheric conditions, leading to the suppression of hurricane activity in the Atlantic Basin. El Niño creates stronger wind shear, which makes it difficult for hurricanes to form and intensify. On the other hand, La Niña, the cold phase of ENSO, can enhance hurricane activity in the Atlantic.

The MJO can also influence hurricane activity. When the MJO is in its active phase, it can create more favorable conditions for tropical storm development, such as increased moisture and decreased wind shear. Conversely, during the inactive phase of the MJO, hurricane activity tends to be suppressed.

The correct answer is c. Mobility. The function of flagella is to provide mobility or movement to certain cells or organisms.

Flagella are long, whip-like appendages that extend from the surface of a cell. They are primarily found in prokaryotic and eukaryotic cells that require the ability to move through fluid environments.

Flagella work by propelling the cell or organism through a whip-like motion. The movement of flagella allows cells to swim or navigate through liquids such as water or mucus. This mobility is important for various biological processes, including locating nutrients, escaping harmful substances, and finding suitable environments for growth and reproduction.

It's worth noting that flagella have different structures and mechanisms of movement in different organisms. Bacterial flagella, for example, are composed of protein filaments that rotate like a propeller to generate movement. Eukaryotic flagella, found in organisms such as sperm cells and certain single-celled organisms, exhibit a bending motion caused by the coordinated movement of microtubules.

In summary, the primary function of flagella is to provide mobility to cells or organisms, enabling them to move in fluid environments.
