John Needham made a mistake of re-contaminating his solutions made from cooked broth.
Needham firmly believed in the spontaneous production of microbes, as did many other scientists of the age. In 1750, he reported the findings of an experiment he had carried out in the hopes of proving the theory of spontaneous generation. His research showed that there was spontaneous generation.By executing an experiment in which he put a broth or gravy inside a container, heated the bottle to kill anything within, and then sealed it, John Needham in England refuted Redi's findings. A few days later, he revealed that there was life in the soup and declared that life had been fashioned out of nothing.However, he did a mistake where he accidentally re-contaminated his solution.

The median for the number of snails of the 30 segments of this Alabama creek is equal to C. 21.
What is a median?In Mathematics, a median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
How to calculate the median number of snails?First of all, we would sort the number of snails from the least to greatest as follows:
1, 4, 6, 8, 9, 10, 11, 12, 15, 15, 16, 17, 18, 20, 21, 21, 23, 23, 24, 24, 24, 25, 29, 29, 32, 32, 33, 36, 40, 40.
The median for the number of snails of the 30 segments is the average of the 15th and 16th number:
Median = (21 + 21)/2

Another method for lowering the risk of breast cancer in mutation carriers is chemotherapy.
The greatest potential benefit has been linked to risk-reducing surgery for women who have a gene mutation that increases their risk of breast cancer.
What is Breast and ovarian cancer ?An inherited cancer-predisposition condition is the hereditary breast and ovarian cancer (HBOC) syndrome. Affected people are far more likely to acquire specific types of cancer, especially ovarian cancer in women and breast cancer in both men and women.
BRCA1 and BRCA2 are the two main genes associated with the majority of families with HBOC. Breast cancer is referred to as BRCA.

If the pride is taken over by new individuals, what happens to the females? males? cubs?.
The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.
Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.Learn more about pride here:

patterns and location of velopharyngeal valving problems: atypical findings on video nasopharyngoscopy
In 246 consecutive nasopharyngoscopy examinations, patterns of velopharyngeal (VP) valving and the location of velopharyngeal gaps were examined.
Velopharyngeal: What is it?Normal speech production depends heavily on the velopharyngeal valve. The structures that make up this valve are as follows:
Velum (also called soft palate) The side walls of the throat are called lateral pharyngeal walls. The back wall of the throat is known as the posterior pharyngeal wall.The coronal pattern of closure predominated (68%) and was followed by circular (23%), circular with a Passavant's ridge (5%) patterns, as well as sagittal (4%) patterns. In 181 patients, gaps were discovered, in 121, they were deemed typical (centrally located), in 28, they were in one of the lateral aspects of the valve, and in 32, they were attributed to abnormalities in the anatomy or function of the posterior border of the soft palate or to the shape of the adenoid tissue. Patients with a coronal valving pattern tended to have abnormal results. These findings highlight additional concerns regarding the care of patients with unusual valving issues.

When an archaeologist finds an ancient artifact on a dig, how should they determine its relative age?.
There are several ways for an archaeologist to determine the relative age of an ancient artifact on a dig.
The first one is relative dating. In this process, the archaeologist has to assume that the sites lower layers are assumed to be older than those that lie above them because of stratification. Assumptions can be wrong that is why it is not widely accepted.
The second one is carbon dating. It is one the most accurate and widely use dating techniques. The archaeologists use the amount radioactive carbon decay to determine the artifact's date.
There are other techniques as well like Thermoluminescence dating, and Dendochronology.

in the phase of wound healing, collagen closes the gap between tissues and scar tissue forms
In the phase of wound healing, collagen closes the gap between tissues, and scar tissue forms. This phase is called the Remodelling phase because collagen continues to increase, and the tissue begins to contract with the help of fibroblasts, which adds strength to the new tissue.
However, gradually excessive collagen in the fibrin framework can cause scar tissue formation.
Therefore, at the injury site, the fibrin in blood stops the blood flow and provides mechanical support to the collagens, a protein that helps close the gap between injured tissues and gives strength to the newly formed tissue. This phase continues for six or more months. Thus, it is called as remodel or remodelling phase.

what adaptations have allowed tetrapods to survive on land
Answer:
It is extremely useful for terrestrial organisms because it allows them to use their hindlimbs efficiently for locomotion on land. Since the aquatic ancestors of fishes and tetrapods had no such connection, one might guess that this feature first evolved serving the function of enabling terrestrial locomotion.
Answer: When the land animals began to use the fins for standing and walking, the girdle bones had to become stronger to support the body on the legs. These bones eventually became the femur (upper leg bone) and humerus (upper arm bone) of the tetrapods

Explain over production and reproduction
Explanation:
Overproduction in Natural SelectionNatural selection occurs in specific populations of organisms because of several factors. It begins with overproduction. Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment. Because of this, competition takes place for limited resources. Individuals have traits that are passed down to offspring. Some of these traits give individuals an advantage when it comes to surviving to reproduce. The organisms with these traits are more likely to live and have offspring who will inherit the helpful traits.
