Answer:

The dominant gene determines phenotype

Explanation:

This is because some parents have dominant and recessive alleles. when they pass them on to their offspring,the more dominant genes they have,the higher the chance that trait will show in their offspring.

When a parent passes a dominant gene to their child, the dominant gene determines the phenotype.

Dominant genes are those that determine a hereditary trait even when in single dose in the genotype. That is, they determine its character even in the absence of its dominant allele.

With this information, we can conclude that when a parent passes a dominant gene to their child, the dominant gene determines the phenotype.

Answer:

If you looked at a karyotype of a germ cell - egg or sperm cell - you would see only 1 of each chromosome in a karyotype, not two!!! Germ cells have only half the number of chromosomes as a diploid cell one of each pair. The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis.

Explanation:

Karyotypes are like representations to indicate the number of chromosomes of a particular organism.

The karyotype shown after meiosis will be left with just 23 single chromosomes (not in pairs). They are haploid cells.

The organism got this karyotype from the contribution of the both parents nuclei (haploid egg cell and haploid sperm cell) fusing to give rise to a cell with diploid chromosomes.

The statement "men need to inherit only one copy of the recessive allele for the condition to be fully expressed" is partially true because  It depends on the specific condition and whether it is sex-linked or autosomal.

In autosomal recessive conditions, both males and females need to inherit two copies of the recessive allele in order for the condition to be fully expressed. This means that if a male inherits only one copy of the recessive allele, he will be a carrier of the condition but will not show any symptoms.

However, if he has children with a carrier female, there is a 25% chance that their offspring will inherit both copies of the recessive allele and thus show symptoms of the condition.

In contrast, some conditions are sex-linked and are carried on the X chromosome. Males have only one X chromosome, so if they inherit a recessive allele for a sex-linked condition from their mother, they will show symptoms of the condition.

This is because they do not have another X chromosome to offset the effects of the recessive allele. Females, on the other hand, have two X chromosomes and would need to inherit two copies of the recessive allele to show symptoms of a sex-linked condition.

In summary, the statement is true for some sex-linked conditions but false for autosomal recessive conditions. It is important to understand the inheritance pattern of specific genetic conditions to accurately interpret their expression in males and females.

Explanation:

Answer:

Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.There are basically 2 types of changes that occur to the earth's surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process.

Explanation:

Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. When it comes to changes on the Earth's surface, the main processes to take into account are plate tectonics and the rock cycle as well as the sea-floor spreading. ... These collisions causes mountains and volcanoes to form on the plate boundaries and thus changes the shape and form of the landmass

If the apple snail population were to decrease, the limpkin, a secondary consumer that eats mainly apple snails, would have to find an alternative food source in order to adapt to its environment. This could involve finding other types of snails or mollusks to eat, or potentially switching to a diet that includes other types of prey. The limpkin may also need to range over a larger area in order to locate sufficient food, or it may need to change its foraging behavior in order to more effectively locate and capture its preferred prey. Ultimately, the limpkin's ability to adapt to a decline in the apple snail population will depend on the availability of other suitable food sources and the flexibility of its foraging behavior.

Taking into account the constitution of an atom and the definition of atomic number, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.

Every atom consists of a nucleus in which neutrons and protons meet and energy levels where electrons are located.

In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.

Atoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom.

This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. Then it is possible to say that the atomic number Z determines its identity.

Finally, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.

Explanation:

The brain activity technique that would likely be used to assess a patient with difficulty getting glucose to the occipital lobe of the brain is a positron emission tomography (PET) scan.

PET scans use a radioactive tracer to track the flow of glucose and other substances in the brain. The tracer is injected into the bloodstream and binds to glucose, which is then metabolized by the brain's cells. As glucose is metabolized, it releases positrons, which can be detected by the PET scanner.

By tracking the flow of glucose in the brain, PET scans can provide information about brain activity and metabolism. In a patient with difficulty getting glucose to the occipital lobe of the brain, a PET scan could help to identify areas of reduced activity or metabolism in this region.

EEG and functional MRI (fMRI) are other brain activity techniques, but they would not be the most appropriate for assessing a patient with difficulty getting glucose to the occipital lobe. EEG measures the electrical activity of the brain and is commonly used to diagnose seizures and other neurological conditions. fMRI measures changes in blood flow in the brain and is often used to study brain function during specific tasks. Neither of these techniques would provide direct information about glucose metabolism in the brain.

The self-limiting and nonfatal nature of gastrointestinal diseases, with fluid replacement, explains their global prevalence. These disease characteristics contribute to the presence of diverse pathogens causing gastrointestinal illnesses.

Gastrointestinal tract diseases being self-limiting and nonfatal, as long as fluids are replaced, means that most individuals can recover from these diseases without medical intervention. This observation helps explain why such diseases are commonly found in humans worldwide.

As long as proper hydration is maintained by replacing fluids lost due to vomiting or diarrhea, the body can overcome these diseases on its own. This self-limiting nature allows the diseases to run their course and resolve without necessarily causing severe consequences, leading to a high prevalence across different populations.

The self-limiting and nonfatal characteristics of gastrointestinal tract diseases make it possible for a wide range of pathogens to cause these diseases. Since most individuals can recover without medical intervention, the body's immune system can effectively combat and eliminate various pathogens.

This means that different pathogens, such as bacteria, viruses, or parasites, can cause gastrointestinal diseases without necessarily causing severe harm or fatalities. This flexibility allows for a diverse range of pathogens to thrive and cause gastrointestinal diseases in humans, leading to the observed variety of causative agents.

Explanation:

The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:

1) The Physical principle: conservation of momentum.

If there is no net external force operating on a system, so the system's total momentum is conserved

The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:

P = mv.

2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.

Based on this, the calculation is as follows

Momentum before the collision:

       \(P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity\)

       \(P_1 = (60kg + m) \times v_1\)

= 340 kg m/s

Now Momentum after the collision:

      \(P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike\)

\(P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2\)

\(P_1 = P_2\)

\(= (60kg + m) \times v_1\)

\(= 60kg \times v_2\)

\(= 340 kg .\ m/s\)

\(= 60kg \times v_2\)

\(v_2 = \frac{340\ kg .\ m/s }{60\ kg}\)

= 5.7 m/s     

The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The given parameters;

The velocity of Sheila immediately after she is thrown from the bike is calculated as follows;

P = mv

where;

v is the velocity Sheila

\(v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s\)

Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The hydrologic cycle is a process by which water circulates through the Earth's atmosphere, oceans, and land, linking them in a continuous cycle.

During this cycle, water moves between the oceans, land, and atmosphere through evaporation, precipitation, transpiration, runoff, infiltration, and storage. The hydrologic cycle is an essential process for the Earth's ecosystems, as it distributes freshwater and supports life on the planet.

Q3: Do you think the reservoir gains or loses water?

A reservoir can gain or lose water depending on the balance between the amount of water entering and leaving the reservoir. If the inflow is greater than the outflow, the reservoir will gain water, and if the outflow is greater than the inflow, the reservoir will lose water.

Q4: How much?

The amount of water gained or lost by a reservoir will depend on various factors such as the size of the reservoir, the amount of precipitation, evaporation, and human use. Therefore, it is not possible to provide a specific value for the amount of water gained or lost by a reservoir without considering these factors.

The stage of development synonymous with a cocoon, where the caterpillar morphs into a beautiful butterfly, is called the "pupa" stage. This stage is the third of the four stages in the butterfly's life cycle. The life cycle begins with the egg, followed by the larva or caterpillar stage, then the pupa stage, and finally the adult butterfly stage.

During the pupa stage, the caterpillar forms a protective outer shell, known as a chrysalis or cocoon, around itself. Inside the cocoon, the caterpillar undergoes a remarkable transformation called metamorphosis. This process involves the breakdown of the caterpillar's body tissues, which are then reorganized into the body structure of the adult butterfly. The metamorphosis process can take anywhere from a few days to several weeks, depending on the species.

Once the transformation is complete, the adult butterfly emerges from the cocoon, having changed significantly in both appearance and behavior. The newly emerged butterfly will need some time to dry its wings and strengthen its body before it can take flight. From this point on, the butterfly will focus on finding a mate and reproducing, thus continuing the life cycle.
