Answer:
Primary Succession
Explanation:
Because no organisms previously lived on it. Parking lots can be considered
like rocks, which also undergo primary succession. Overtime soil will be blown onto the parking lot and if not maintained plants
will begin to grow thus starting new life.
Primary succession will occur if parking lot is abandoned for 1000 years.
What is primary succession?The process of establishing plant and animal communities in a place that was previously devoid of life, like barren rock or a recently formed island, is known as primary succession.
Lichens and mosses would first colonize the bare pavement in the abandoned parking lot as the first stage of primary succession, which would then be followed by the emergence of grasses, shrubs, and eventually trees.
A more diverse and complex ecosystem would eventually develop as a result of the plant community's ability to sustain and attract a wide range of species over time, including insects, birds, and mammals.
Depending on a variety of environmental circumstances, the total process of primary succession may take hundreds or even thousands of years.
Thus, the answer is primary succession.

What does earths rotation on it’s axis cause
Final answer:
Earth's rotation on its axis causes day and night cycles, affects weather through the Coriolis effect, and leads to seasonal changes due to Earth's axial tilt. The rotation also contributes to the precession of Earth's axis over a period of about 26,000 years.
Explanation:
The Earth's rotation on its axis causes several significant phenomena. One key aspect is the alternation between day and night. As the Earth spins, different parts of its surface move into and out of the Sun's light, resulting in the cycle of day and night. Additionally, the Earth's rotation on its axis is responsible for the Coriolis effect, which affects weather patterns and ocean currents.
Seasonal changes are another major effect of Earth's axial rotation, further influenced by its axial tilt of approximately 23.5°. This tilt causes different parts of Earth to receive varying amounts of sunlight through the year as it orbits around the Sun, leading to the seasons. For instance, when the Northern Hemisphere is tilted towards the Sun, it experiences summer, while the Southern Hemisphere, tilted away, experiences winter, and vice versa.
The rotational motion also contributes to precession, a slow gyroscope-like turn of the entire Earth over a cycle of about 26,000 years, mainly due to the gravitational pull exerted by the Sun and Moon on the Earth's equatorial bulge.

Which of the following are allies to the immune system
Mucous Membranes
Digestive system
Skeletal System
Skin
Final answer:
The allies to the immune system include mucous membranes and skin, which are physical barriers against pathogens. The mucous membranes contain MALT which protects mucosal surfaces. The digestive and skeletal systems support the body's overall health and indirectly benefit the immune system, but they are not direct allies in the same manner as the mucous membranes and skin.
Explanation:
The body has multiple defenses against potential infections, each contributing in different ways to the immune system. Among these defenses are the mucous membranes and the skin, which act as physical barriers to pathogens. The mucous membranes are part of both the innate and mucosal immune systems, containing mucosa-associated lymphoid tissue (MALT) that protects the mucosal surfaces, such as the nasal passages and the gastrointestinal tract, against microbial invasion. Skin is a part of the integumentary system and also serves as a first line of defense by providing a barrier to outside pathogens and contributing to the innate immune system.
While the digestive system and skeletal system are not typically considered allies of the immune system in the same way, they do play supportive roles. The digestive system benefits from the actions of the immune system, particularly MALT, which defends against pathogens entering through the gastrointestinal tract. The skeletal system contributes to overall health by protecting organs, producing blood cells, and supporting the body, indirectly aiding the immune system by maintaining the body's structural integrity, but it is not directly involved in immune defense like the skin and mucous membranes.

A plant has two alleles for color the red allele is recessive and is represented by q the purple allele is dominant and is represented by p if 76 of 100 organisms are red what is q
Answer:
0.87Explanation:
As given
q=red (recessive)
p=purple (dominant);
According to Hardy-Weinberg law;
(p+q)= 1 = p²+ 2pq+ q²
As the information provided, the red allele is recessive and it is represented by q
so q²= 76/100 = 0.76
Now we can find the recessive allele frequency using it as q is the frequency of recessive allele.
Thus, q= √0.76
q= 0.8717797887
Thus, the value of q is 0.871

The blind mole rat is a close relative of other rats. However, mole rats live underground for their entire lives. As a result, their eyes have evolved into useless structures. Presumably, mole rats will not have eyes at all in the distant future. What type of structures are the mole rat's eyes?
Answer:
rudimentary eyes
Explanation:
Rudimentary eyes are eyes covered by skin that do not respond to visual stimulation.
The eyes of a blind mole rat represent vestigial structures. These are body parts that lose their original function through evolution. The mole rat's eye evolution hints at ancestral adaptations where eyesight was beneficial.
Explanation:The eyes of the blind mole rat are considered vestigial structures. These are body parts that have lost their original function through evolution. In the case of the blind mole rat, living in darkness underground, there is no need for vision. Thus, their eyes have evolved into structures that do not serve to perceive visual input.
Studying such structures provides valuable insight into an organism's evolutionary history. For example, we can surmise that the blind mole rat's ancestors had functioning eyes, implying they lived under conditions where eyesight was beneficial.

Answer:
He concluded that all cells come from preexisting cells.
Explanation:
Rudolf Virchow while building on the work of Theodore Schwann formulated a part of the cell theory which opined that cells arose from pre-exsiting cells which disproved the theory of spontaneous generation
Although this assertion has earlier been made by another scientist, Robert Remak in 1852, Schwann did not accept until later until after series of investigations. Schwann was later accused of publishing the work of Robert Remak as his in 1855.

Explanation: Rudolph Virchow state that 'Omnis cellula e cellula' which means that every cells arise from preexisting cells. Until Virchow came out with this theory, it was believed that new cells were created from a fluid called blastema ( it was believed that the imbalance caused disease).
Rudolf Virchow's lay the ground work on cellular pathology ( that is the study of disease at the cellular level). His work made it more clear that diseases occur at the cellular level and not blastema as believed. Diseases were diagnosed more accurately by scientist due to Rudolf Virchow's work.

How does the excretory system work with the digestive system to maintain homeostasis?
Answer:
After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body. The excretory system also maintains fluid homeostasis.
Explanation:
Final answer:
The excretory system works with the digestive system to maintain homeostasis by removing digestive wastes and maintaining water and salt balance, with the kidneys and liver playing central roles in this process.
Explanation:
The excretory system maintains homeostasis by removing wastes, excess water, and other substances that are not needed by the body. The kidneys are the primary organs in this system, containing numerous nephrons that filter blood, absorb, secrete substances, and form urine. Meanwhile, the digestive system breaks down food into its component nutrients which can be absorbed into the bloodstream. Once absorbed, the circulatory system transports these nutrients throughout the body.
However, the process of digestion also produces waste products, which are excreted. The liver plays a crucial role in both systems by metabolizing toxins and waste products from digestion before they reach the kidneys. The liver's ability to convert ammonia into urea, which is then excreted by the kidneys, is one way the two systems interact to maintain homeostasis. Moreover, water and salt balance, which are significant for homeostasis, are managed through the digestive intake and renal excretion. Thus, the excretory system, including the kidneys and the digestive system, works collectively to maintain the internal balance required for optimal body function.
