It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.
The "master controller" gland is the _____. thyroid adrenal pituitary thalamus
Answer:
Hypothalamus is the correct answer to the given question.
Explanation:
Hypothalamus in the brain is the tiny portion of the mind also the Hypothalamus is situated at the foot of the nervous system .The Hypothalamus is just next to the pituitary gland. Hypothalamus is produced by a variety of nucleus as well as the nervous fibers. It's own neuronal links
The main objective of Hypothalamus is to hormonal fluctuation as well as controlling the temperature of the body.All the other option is not the master controller gland that's why these are incorrect option .Answer:
The pituitary gland is the master controller gland.
Explanation:
I just did this: The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands.

Which example is most likely made from both metals and gemstones?
Necklace
Soda can
Widow frame
Kitchen utensils
Answer:
A. necklace
Explanation:
Necklace is most likely made from both metals and gemstones.
What is necklace?A necklace might be a straightforward chain made of gold or silver, a string of beads or diamonds, or a pendant suspended from a rope. It qualifies as a necklace as long as it is worn around the neck.
Unless you are a professional or amateur geologist—or perhaps you earned a merit badge studying them as a scout—you probably won't be able to explain the differences between these four hard natural materials: minerals, rocks, gemstones, and crystals.
The different types of necklace are chocker, Matinee and opera. Long and functional, opera length necklaces. The necklace should hang below the bust when worn as a single strand.
Therefore, Necklace is most likely made from both metals and gemstones.

what kinds of bacteria are spherical, endospores,cocci, bacilli, spirilla
The cocci kind of bacteria are spherical in shape. Rod-shaped bacteria are bacilli, and spiral-shaped bacteria are called spirilla. Thus, the correct option is C.
What are the cocci bacteria?A coccus or cocci bacteria is any bacterium or archaeon which has a spherical, ovoid, or generally a round shape. Bacteria are categorized into different classes on the basis of their shapes into three classes which are cocci (spherical-shaped bacteria), bacillus (rod-shaped bacteria) and spiral (two types: spirillum and spirochete bacteria).
Different classes and examples of bacteria are Streptococci, in which cocci are arranged in chains. Example: Streptococcus mutans. Diplococci, in this cocci are arranged in pairs. Example: Neisseria gonorrhoeae. Monococci are single cocci. Staphylococci are the clusters of cocci. Example: Staphylococcus aureus.
Therefore, the correct option is C.

Hope its helpful ❤❤❤❤❤A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.
What are some of the consequences of acid rain? Thanku
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released, die of biodiversity in environment and other organism that supports decomposition of material
