Explain how Rutherford's students knew that
Thomson's model of the atom needed to
change.
Answer:
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

overheating an enzyme results in the enzymes loss of
Answer:
shape or denaturation
Explanation:
An enzyme loses its capacity to catalyze a process when it becomes too hot, hence option B is correct.
An enzyme loses its capacity to catalyze a process when it becomes too hot. This is due to the fact that heat provides the enzyme molecules' atoms with sufficient kinetic energy to dissipate the intermolecular interactions keeping them in place.
The rate of an enzyme-catalyzed reaction increases as the temperature rises, as it does with many other chemical processes. High temperatures, however, cause the enzyme to become denatured and cease functioning, which causes the rate to decline once more.

What other traits are highly variable like human skin color ? List at least three
Answer:
Our lack of body hair and our variable skin color are some of the traits that set us apart from our closest primate relatives. Wavelengths of light are reflected or absorbed by pigment in the skin called melanin. Melanin is synthesized in structures called melanosomes that are produced by cells called melanocytes.
Explanation:
Skin colour varies considerably from person to person and is generally of their characteristics:
By the presence of melanocytes, carotene, Oxygenated haemoglobin, and Blood flow.What type of variable is skin colour?"Skin colour is a classic variable characteristic in humans, and it's thought to be adaptive," Tishkoff said. "Analysis of the genetic root of variation in skin colour sheds light on how adaptive traits evolve, including those that play a role in disease risk."
Thus, the presence of melanocytes, carotene, oxygenated haemoglobin, and blood flow.

Answer:
Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them
Explanation:
Answer:
The mass of the objects and the distance between them.
Explanation:
The more mass two objects have, the greater
the force of gravity the masses exert on each other. If one of the masses
is doubled, the force of gravity between the objects is doubled.

How does the stratigraphic principle help us determine the age of layers of rocks?
Answer:
The principles of stratigraphy help us understand the relative age of rock layers. Layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontal). Younger layers are deposited on top of older layers (principle of superposition). Layers that cut across other layers are younger than the layers they cut through (principle of cross-cutting relationships). The principle of superposition builds on the principle of original horizontal. The principle of superposition states that in an unreformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it. Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.

What is a transgenic organism?
A an organism that is an exact clone
B an organism that has no dna
C and organism that has a mixture of dna
D an organism with dna from another organism
Answer:
Transgenic organisms is an organism with dna from another organism.
A transgenic organism is an organism that contains DNA from another organism. Option D is correct.
Transgenic alludes to a life form or cell whose genome has been changed by the presentation of at least one unfamiliar DNA successions from one more animal groups by counterfeit means. For research purposes, transgenic organisms are created in the laboratory.
A transgenic organism, also known as a genetically modified organism, is one that has been altered by recombinant DNA technology. Recombinant DNA technology involves either combining DNA from various genomes or inserting foreign DNA into a genome.

1. Osmosis and diffusion (simple diffusion) are examples of passive or active transport? How do
you know?
Answer: While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules.
Explanation:
Answer:
Passive transport.
Explanation:
Osmosis and diffusion because a single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

Use chromosomes 11 and 17 to answer the following questions. Chromosome Map Chromosome 17 is made of over million base pairs. Approximately how many genes are found on chromosome 17? List the genetic disorders found on chromosome 17. What do you know about any of those disorders?
Answer:
Hello!
Chromosome 17 is made of over 80 million base pairs.
Approximately how many genes are found on chromosome 17? 1600
Explanation:
Chromosome 17 is made up of more than 80 million base pairs. Approximately, 1600 genes are found on chromosome 17. The genetic disorders found on chromosome 17 are as follows:
Breast cancer.Neurofibromatosis.DNA damage response in individuals.Scoliosis.Congenital heart anomalies. What are Chromosomes?Chromosomes may be defined as thin, thread-like structures that may appear in the nucleus of the cell during the process of cell division. These structures may contain DNA, RNA, histones, and non-histone proteins. Chromosomes may be discovered by E. Strasburger in 1875.
Human chromosome 17 is implicated in a wide range of human genetic diseases. It is home to genes involved in many genetic disorders that may affect the physiology of an individual. They are very severe to organisms.
Mosaic trisomy 17 is a rare chromosomal anomaly syndrome, with a highly variable clinical presentation, mostly characterized by growth delay, intellectual disability, body asymmetry with leg length differentiation, scoliosis, and congenital heart anomalies.
