There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.

The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.

The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).

We know that the frequency of heterozygotes is 0.21, or 21%.

Plugging in the known values:

2 * 0.7 * q = 0.21

Solving for q:

q = 0.15

So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.

The statement "our entire blood volume circulates through your kidneys" is absolutely false.

The function of the kidneys is to cleanse the blood of toxins and transform the waste into urine. The human body consists of two kidneys. Each kidney weighs about 160 grams and gets rid of between one and one-and-a-half liters of urine per day. The two kidneys together filter 200 liters of fluid every 24 hours.

About one-quarter of the total cardiac output (or total blood flow) circulates through the kidneys. This equates to just over 1 liter of blood every minute. So, it is incorrect to say that our entire blood volume circulates through our kidneys.

Therefore, the statement "our entire blood volume circulates through your kidneys" is absolutely false.

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.

Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.

Describe three different strategies used by three different animals to thermoregulate.

If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?

If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.

Answer:

1. central

2. action potential

3. nerve net

4. dorsal

5. hydrostatic

6. Exoskeletons

7. contraction/contracting

8. Fertilization

9. external fertilization

10. Eggs

11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.

12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

Match the size and shape of rocks on the north and south edges of Australia is the method that describes the study of plate movements known as paleomagnetism

What are plate movements ?

Plate movements refer to the large-scale motions of the rigid lithospheric plates that make up the Earth's outer shell. The lithosphere is broken up into a number of plates that move relative to each other due to the underlying convective movements of the Earth's mantle. This movement can occur in a variety of ways, including spreading apart at mid-ocean ridges, colliding and converging at subduction zones, and sliding past each other at transform faults.

Plate movements can have significant effects on the Earth's surface and can cause a wide range of geological phenomena, including earthquakes, volcanic eruptions, mountain building, and the formation of ocean basins. These movements are driven by the transfer of heat from the Earth's interior to its surface and are responsible for shaping the planet's geography over long periods of time.

The study of plate movements is an important field in geology and earth science, as it helps us to understand how the Earth's surface has changed over time and how it will continue to change in the future

Match the size and shape of rocks on the north and south edges of Australia is the method that describes the study of plate movements known as paleomagnetism

This technique involves examining the magnetic properties of rocks and matching them to the Earth's magnetic field at the time they were formed. By comparing the magnetic properties of rocks on different continents, scientists can determine the past positions and movements of the continents and the plates they sit on.

B, the cell membrane

Explanation:

The cell membrane dictates what enters and exits the cell. It keeps the important stuff (such as organelles) inside the cell, allows nutrients to enter the cell, and keeps unwanted ¨things¨ from entering. The tea bag does roughly the same thing.

It keeps the important contents inside (in this case the tea leaves), allows water to come inside, and keeps whatever is in the water outside of the teabag. Obviously the cell membrane is much more complicated than a tea bag, but the tea bag works as a nice analogy.

Angelman syndrome is characterized by intellectual disability, severe speech impairment, ataxia, seizures, and a happy demeanor. Prader-Willi syndrome involves hypotonia, hyperphagia, obesity, intellectual disability, behavioral problems, and short stature.

Angelman syndrome and Prader-Willi syndrome are two distinct genetic disorders that are often discussed in the context of epigenetic inheritance. Both conditions result from abnormalities in a specific region of chromosome 15, but they have opposite effects due to differential genetic imprinting.

Angelman syndrome is characterized by developmental delays, severe intellectual disabilities, speech impairments, and motor coordination problems.

Individuals with Angelman syndrome often exhibit a happy and excitable demeanor, with frequent episodes of laughter and a fascination with water. They may also experience sleep disturbances, seizures, and a lack of speech development.

On the other hand, Prader-Willi syndrome manifests with distinct symptoms such as hypotonia (poor muscle tone) during infancy, hyperphagia (insatiable appetite) leading to obesity, developmental delays, learning difficulties, and behavioral challenges.

Individuals with Prader-Willi syndrome often have a compulsive need for food and struggle with weight management. They may also experience hormonal imbalances, growth hormone deficiency, and behavioral issues such as temper tantrums and obsessive-compulsive behaviors.

Epigenetic inheritance refers to the transmission of information from one generation to another that affects gene expression without altering the underlying DNA sequence.

In the case of Angelman and Prader-Willi syndromes, these conditions result from epigenetic changes, specifically imprinting, in the chromosomal region involved. Imprinting refers to the process by which certain genes are marked or silenced based on their parental origin.

In Angelman syndrome, the paternal copy of the UBE3A gene is deleted or silenced, leading to a lack of functional UBE3A protein in the brain. In Prader-Willi syndrome, the maternal copy of the same gene is affected. These imprinted genes play critical roles in brain development and function, leading to the distinct symptoms observed in each disorder.

It is important to note that while both Angelman and Prader-Willi syndromes are considered examples of epigenetic inheritance, the underlying mechanisms and specific epigenetic changes involved are complex and continue to be studied.
