The planets orbit the Sun in the same plane and the Big Bang Theory states an explosion of space, marked the beginning of our cosmos.

The galactic plane and the planetary orbital plane form a roughly 60° angle as the Solar System travels through the galaxy.

As it circles around the Milky Way, the Sun appears to move up and down and in and out of the galaxy.

The Big Bang, an explosion of space, marked the beginning of our cosmos. Space expanded, the cosmos cooled, and the basic elements emerged from a very high density and temperature starting point.

The first stars and galaxies were created as a result of the slow gathering of stuff by gravity.

There are 6.25% homozygous dominant people (AA), 37.5% heterozygous people (Aa), and 56.25% homozygous recessive people (aa).

In a population with two alleles, p and q, the frequency of p and q must add up to 1, or 100%. In this case, p = 0.25 and q = 0.75.

Using the Hardy-Weinberg equation, we can calculate the expected frequencies of the three possible genotypes: AA, Aa, and aa. The equation is:

p² + 2pq + q² = 1

where p² represents the frequency of the AA genotype, 2pq represents the frequency of the Aa genotype, and q² represents the frequency of the aa genotype.

Substituting the given values of p and q:

(0.25)² + 2(0.25)(0.75) + (0.75)² = 1

0.0625 + 0.375 + 0.5625 = 1

Therefore, the expected frequencies of the three genotypes are:

AA = p² = (0.25)² = 0.0625

Aa = 2pq = 2(0.25)(0.75) = 0.375

aa = q² = (0.75)² = 0.5625

So in this population, we would expect to see 6.25% homozygous dominant individuals (AA), 37.5% heterozygous individuals (Aa), and 56.25% homozygous recessive individuals (aa).

Answer:

B. The prostate gland presses on the urethra

Explanation:

Benign prostatic hyperplasia (BPH) is caused by the proliferation of prostatic cells, which leads to the inflammation of this gland, squeezing the urethra (i.e., the tube where urine passes) and ultimately reducing the flow of urine. BPH is a chronic condition progressive with age, thereby it is associated with old men. Although in principle BPH isn't dangerous, high pressure on the urethra may lead to incomplete emptying bladder and infections in the urinary tract.

Option(B) Ureter is the correct option.

The ureter is a vital part of the urinary system in humans. It is a muscular tube that connects the kidneys to the urinary bladder. Each human has two ureters, one attached to each kidney, and they play a crucial role in the transportation of urine from the kidneys to the bladder.

The primary function of the ureter is to carry urine that is produced in the kidneys to the urinary bladder for storage before it is eliminated from the body through urination. The ureters accomplish this by using peristalsis, a wave-like muscular contraction, to propel urine along their length.

The ureters have a complex anatomical course. They originate from the renal pelvis, which is the funnel-shaped structure that collects urine from the kidneys. From there, they extend downward, crossing over the brim of the pelvis and passing behind the peritoneum, the membrane lining the abdominal cavity.

The efficient functioning of the ureters is essential for the proper elimination of waste products and maintenance of fluid balance in the body. Any obstruction or abnormality in the ureters can lead to conditions like kidney stones, urinary tract infections, or urinary reflux.

In summary, the ureters are muscular tubes that transport urine from the kidneys to the urinary bladder. They rely on peristaltic contractions to propel urine, and their structure and positioning help ensure unidirectional flow.

Explanation:

The answer is option A, Technology.

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.

Answer: a scar and wolf's social status

Explanation:

The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.

The trait that should be put in section II (Both) is "a scar", as scars can be acquired due to injury or trauma, but some people may also have a genetic predisposition to scarring.

Inherited traits are characteristics that are determined by an individual's genetic makeup and are passed down from parents to their offspring through the process of reproduction. Examples of inherited traits include eye color, hair color, blood type, and facial features.

Acquired traits are characteristics that are developed during an individual's lifetime as a result of their interactions with the environment. Examples of acquired traits include scars, calluses, tanned skin, learned behaviors, and language proficiency.

While some traits may be either entirely inherited or acquired, many traits are influenced by both genetic and environmental factors. The complex interplay between nature and nurture contributes to the vast diversity of traits and characteristics found within the human population.

The chemical messengers are called as neurotransmitters as these are the sites on the dendrites. These are responsible for the transmission of signal in the nervous system.

Neurotransmission is a process by which signaling molecules called neurotransmitters are released from neurons. These are responsible for the transmission of nerve impulse across synapse.

Neurotransmitters are present in the axons of pre-synaptic neurons and are released into the dendrites of post-synaptic neurons. When a particular number of chemical messengers are released and attached to the post-synaptic neurons then the neuron reaches the point of firing called Threshold potential.

Neurons either fire together or they don't. This is called as All-or-none impulse. The firing is called a nerve impulse, which is also called as Action Potential.

The impulse travels down the length of pre-synaptic neuron axon to the distant ends of the terminal branches of axons and through this impulse is transported to dendrites of post-synaptic neurons.

The transportation of neurotransmitters from pre-synaptic neurons to the post-synaptic neurons is called as Synapse. This whole transport of synapse is called Neurotransmission.

(b) Describe the role of phospholipid molecules in the cell surface membrane.

Phospholipids are the major component of the cell surface membrane and are responsible for its physical structure and integrity. They form a bilayer, with the two layers of phospholipids arranged in a ‘mosaic’ pattern. The hydrophobic tails of the phospholipids are embedded in the centre of the membrane and their hydrophilic heads form the inner and outer surfaces of the membrane, facing the cytoplasm and the external environment respectively. This structure enables the membrane to act as a selective barrier, allowing certain molecules and ions to cross it, while preventing others from entering or leaving the cell.

Mitochondrial diseases are caused by mutations in the mitochondrial DNA, which is located in the mitochondria. These mutations are usually inherited from the mother, as the mitochondrial DNA is passed down from the mother to her children.

Mitochondria are organelles found in the cells of all eukaryotic organisms, which are responsible for generating most of the cell’s supply of chemical energy. They are often referred to as the “powerhouses” of the cell. Mitochondria are essential for life and are involved in a variety of cellular processes, such as metabolism, cell growth, and cell death. They contain their own DNA and can replicate independently from the cell. Mitochondria are also involved in several metabolic pathways, such as the tricarboxylic acid cycle, the beta-oxidation of fatty acids, and the synthesis of amino acids. Mitochondria are essential for life and have been linked to a variety of degenerative diseases, such as Parkinson's disease, Alzheimer's disease, and diabetes.

It is very rare for a mitochondrial disease to be inherited from the father or contracted from a viral, bacterial, or parasitic infection.
