Answer:
The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.
Explanation:
During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

Why do prokaryotes not undergo mitosis?
The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

4.Explain how smoking and drinking alcohol by males can affect the development of an embryo.
Answer:
Prenatal exposure to smoking and alcohol increases the risk for Sudden Infant Death Syndrome Physiological changes associated with these exposures are not well studied. Full-term infants were tested within the first 3 days of life.
Explanation:
Answer:
Smoking may also increase a baby's risk of various birth defects, including cleft lip, cleft palate, and clubfoot. Even more frightening is research suggesting that babies whose mothers smoked during pregnancy are more likely to die of sudden infant death syndrome

What are the two types of anaerobic respiration? Describe the two in one paragraph.
Answer:
The two main types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.These strategies of respiration occur while the amount of oxygen available is simply too low to guide cardio respiratory.Alcoholic fermentation converts glucose into ethanol. In alcoholic fermentation, glucose is broken down via glycolysis, and two ATP molecules are released in the method. The pyruvic acid molecules produced for the duration of glycolysis destroy down into ethanol and carbon dioxide. In animals, the technique of lactic acid fermentation, further, happens after the glycolysis process. Pyruvic acid is changed into lactic acid, and muscles is damaged down through lactic acid.
Explanation:
The two types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.
Explain anaerobic respiration
Some microbes, including yeast, can ferment alcohol. This procedure transforms glucose into ethanol and carbon dioxide. Through a sequence of biochemical processes, glucose is turned into pyruvate, which is then transformed into ethanol.
On the other hand, lactic acid fermentation takes place in different types of bacteria and human muscle cells. Lactic acid is produced during lactic acid fermentation from glucose. When there is a shortage of oxygen, such during vigorous exercise when muscle cells are unable to receive enough oxygen for aerobic respiration, this process takes place. Although lactic acid fermentation results in an accumulation of lactic acid, which can contribute to muscle discomfort and tiredness, it also helps renew the NAD+ molecules required for glycolysis to proceed.

According to this food web, which of the following organisms do hawks eat?
Snakes and squirrels
Wolves and mushrooms
Grasshoppers and wolves
Squirrels and mushrooms
Answer:
snakes and squirrels
Explanation:
According to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.
What is the Food web?The food web may be defined as the interconnection of a large number of the food chain with one another and forming a web-like pattern.
In a food web, one organism can hold more than one position. In other words, it is a series of branching lines rather than a straight line. The flow of energy is very difficult to calculate in the food web.
Hawks are the tertiary consumers that eat toads, snakes, squirrels, etc. So, hawks are carnivore organisms. Because of being the tertiary consumers, they significantly depend on secondary consumers.
Mushrooms are decomposers. So, options B and D are eliminated. Option C contains grasshoppers that feed on the grass directly. So, they are primary consumers in the food web.
Therefore, according to this food web, hawks eat the organisms like Snakes and squirrels. Thus, the correct option is A.

Describe the location and names of the parts of the pistil.
Describe the location and names of the parts of the stamen.
What were the differences between the Flower A and Flower B?
How were both flowers similar?
Answer: The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg called ovules. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.

Similarly the development of microscopes drove, somewhat later in the same century, the discovery of cells; Hooke and van Leuwenhoek, like Galileo, were hands-on developers of their instruments.The discovery of the green fluorescent protein (GFP), increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technical advances that have spurred on many areas of cell biology
