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.
10. How are these two processes (photosynthesis and respiration) related?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Why can light microscopes produce images in their natural color, while scanning electron and transmission electron microscopes only produce grayscale images?
Answer:
there's no color info recored
Explanation:
Answer:
The reason is pretty basic: color is a property of light (i.e., photons), and since electron microscopes use an electron beam to image a specimen, there's no color information recorded.

This is when organisms coexist by sharing different resources within their habitat.
Answer:
resource partitioning
Explanation:
Resource partitioning is the division of the limited resources to avoid the competition in ecology chain. The organisms are competing to have limited resources, so they need to find a way of coexisting together and not to endanger each other.
This partitioning is good because it shows how species who have the same needs can live together in the same ecological community.

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.

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.

CELLULAR RESPIRATION
What happens to the energy after cellular respiration? What happens to the carbon dioxide and water?
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.

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.

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.
