3) aa- affected
4) aa- affected
5) Aa - unaffected carrier
6) Aa- unaffected carrier
7) aa- affected
8) aa- affected
9) Aa- unaffected carrier
10) aa- affected
11) Aa- unaffected carrier.
This trait is recessive.
The F1 generation has a 50/50 chance of having unaffected offspring.
Explanation:
1) Given
2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier
3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)
4) They are also shaded in, so they have to have the trait
5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier
6) Same reasoning as #5
7) This is shaded in, the box has to have the trait
8) Shaded in = has the trait/affected
9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier
10) Shaded in = has the trait/affected
11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier
Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.
If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.

How do muscles help the body move?
Answers
Answer:
Muscles pull on joints, which allows us to move. They also assist the body in performing tasks such as chewing and transporting food through the digestive system. Even when we sit absolutely motionless, our muscles are continually moving throughout our bodies.
Explanation:
Answer:
Muscles are attached to bones by tendons and help them to move. When a muscle contracts (bunches up), it gets shorter and so pulls on the bone it is attached to. When a muscle relaxes, it goes back to its normal size. So it helps the body to move by letting us be firm and have the ability to balance and do many things we couldn't without bones.

In what ways are sexual and asexual production in plants similar, and in what ways do they differ?
Answers
Answer: Plants reproduce in two ways: sexually and asexually. . By fusing gametes, sexual reproduction generates children. As a result, the offspring are genetically distinct. Asexual reproduction results in the formation of new people without the fusing of gametes.
Sexual and Asexual Reproduction :
Although there are many distinct methods used by living creatures to reproduce, the majority of these methods may be classified as either sexual or asexual reproduction.
Offspring produced by asexual reproduction are genetically identical to either of their parents. Two parents contribute genetic material during sexual reproduction to create distinct children.
There are benefits and drawbacks to both sexual and asexual reproduction, which is why some creatures use both.

Explain how traits are governed by the genetic material found in the genes within chromosomes in the cell nucleus.
Answers
Answer:
Genes determine which phenotypes you get
Explanation:
When you have a gene, it determines what proteins get bonded together. Such as eye color, hair color, hair type, etc.
When an organism reproduces, its genetic material is passed on to its offspring through the chromosomes in the cell nucleus. Chromosomes are structures that contain the genetic material that makes up an organism's genes. Each organism has a specific number of chromosomes, and each chromosome contains many genes.
During reproduction, the chromosomes from the mother's egg and the father's sperm combine to create a new organism. The resulting offspring inherits half of its genetic material from each parent, and this genetic material determines the traits that the offspring will have. For example, if an organism has a gene for blue eyes, it will pass on this gene to its offspring, and the offspring will have a trait for blue eyes.
Overall, traits are governed by the genetic material found in the genes within chromosomes in the cell nucleus. This genetic material is passed on from parent to offspring, and it determines the traits that an organism will have

Answers
Answer:
Explanation:In the Atlantic and Northeast Pacific, we use the term "hurricane" to describe severe storms with high-velocity winds that rotate around a central, low-pressure core. The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean.
In order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the ocean’s surface that is at least 80° Fahrenheit (27° Celsius). Because it is the interaction of warm air and warm seawater that spawns these storms, they form over tropical oceans between about 5 and 20 degrees of latitude. At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin.
Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well. As the air far above the sea rushes upward, even more warm moist air spirals in from along the surface to replace it.
As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.
Eventually, hurricanes turn away from the tropics and into mid-latitudes. Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.
Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms.
Answer:
The surface process that powers the formation of hurricanes is winds, caused by fast rotation of the Earth.The formation of hurricanes requires a combination of different factors, including warm ocean waters, moisture, and atmospheric instability. However, the primary driver of hurricane formation is the Coriolis effect caused by the fast rotation of the Earth.As the Earth spins, it causes the air and water to appear to curve as they move across the surface, which generates areas of high and low pressure. These pressure differences then create winds that move in circular patterns, which are the basis of hurricanes.So, winds, caused by fast rotation of the Earth powers the formation of hurricanes.
Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the method of reproduction in humans result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process
Answers
For the gene that causes sickle cell disease, there are two possible versions, or alleles: a normal allele and a sickle cell allele. A person who has one copy of the normal allele and one copy of the sickle cell allele is said to be a carrier of sickle cell disease. They have few defective cells and no symptoms because the normal allele is dominant, meaning that its effects are seen even when only one copy is present.
When two carriers of sickle cell disease have children, each parent gives one copy of their sickle cell allele or their normal allele to their offspring. There are four possible combinations of alleles that their children can inherit: normal/normal, normal/sickle cell, sickle cell/normal, and sickle cell/sickle cell. The first combination results in a child who does not carry the sickle cell allele and does not have the disease. The second and third combinations result in children who are carriers like their parents, with one copy of the sickle cell allele and one copy of the normal allele. The fourth combination results in a child who has two copies of the sickle cell allele and will develop sickle cell disease.
Answer: This process of genetic inheritance through sexual reproduction ensures that individuals can inherit a mix of genes from their parents, including the possibility of receiving one copy of a sickle cell gene and one copy of a normal gene, resulting in the carrier state with few defective cells and no symptoms.
Explanation: Sickle cell gene refers to a genetic variant that causes abnormal hemoglobin and leads to sickle cell disease when inherited from both parents. Normal gene refers to the typical gene variant that does not cause any genetic disorders or abnormalities.
The method of reproduction in humans, known as sexual reproduction, involves the fusion of two gametes (sperm and egg) during fertilization. Each parent contributes one set of chromosomes, including the genes, to their offspring.
When it comes to the sickle cell gene, it is inherited in an autosomal recessive manner. This means that the sickle cell trait (having one sickle cell gene and one normal gene) occurs when an individual receives one sickle cell gene from one parent and one normal gene from the other parent.
To illustrate the process:
Each parent has two copies of the gene for hemoglobin, the protein responsible for carrying oxygen in red blood cells.One of the parent's copies has the sickle cell gene (HbS) and the other copy has the normal gene (HbA).The same is true for the other parent, with one sickle cell gene (HbS) and one normal gene (HbA).During reproduction, the parent's sex cells (sperm and egg) are produced through meiosis, a specialized type of cell division.In meiosis, the parent's pairs of chromosomes separate, and the resulting sex cells contain only one copy of each chromosome.Each parent's sex cells randomly combine during fertilization to form a new individual with two sets of chromosomes, one from each parent.As a result, there is a 25% chance that the offspring will receive two sickle cell genes (HbS/HbS) and have sickle cell disease, a 50% chance of receiving one sickle cell gene (HbS/HbA) and being a carrier of the trait, and a 25% chance of receiving two normal genes (HbA/HbA) and not having the trait or disease.
