In a human diploid cell there are _______ pairs of homologous chromosomes.
Answer:
23 pairs
Explanation:
there are 46 chromosomes, but 23 PAIRSBats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others, they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey. Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting behavior of bats be affected by such an environment? A. Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase. B. Bats would be better able to use echolocation, which would improve their ability to find prey. C. Bats would be unable to use echolocation, which would prevent them from finding any prey. D. Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
Answer: C) Bats would be unable to use echolocation which would prevent them from finding any prey.
Explanation: I believe it’s B because if there is a long of noise pollution it would interfere with there echolocation causing them to not be able to find prey.
Answer:
C. Bats would be unable to use echolocation which would prevent them from finding any prey.

Which of the following best describes the effects of water pollution on aquatic ecosystems? a. it can result in fish kills and restrictions on human consumption. b. it can change the physiology of fish. c. it can cause long-term alterations of aquatic ecosystems. d. all of the above please select the best answer from the choices provided a b c d
The correct answer is d. all of the above, as all options justify the effects of water pollution on aquatic ecosystems.
When there's a build-up of contaminants withinside the water, both as poisonous chemical compounds or organic waste, it impacts the quantity of oxygen withinside the water, which makes it tough for the population to breathe. It also can bring about immune suppression and reproductive problems, which could spell doom for aquatic life.
What are water pollutants?Water pollutants are prompted while water our bodies together with rivers, lakes, oceans, groundwater, and aquifers get infected with business and agricultural effluents. When water receives pollution, it adversely impacts all lifeforms that without delay or in a roundabout way rely on this source.
Thus it is clear that all points are valid for water pollution.

Humans and Chimps have over 92% of the same DNA which means we are closely related and have common ancestry. What type of evidence is this?
a. genetic
b. observable
c. fossil record
d. structural
Answer:
a. genetic
Explanation:
DNA holds genetic information in the body
The type of evidence for common ancestry is genetics. The correct option is A.
What is genetics?The research of genes and inheritance. Genetic characteristics and qualities (such eye color and a higher likelihood of contracting a certain disease) are passed from parents to children through heredity.
Learning more about promoting health and preventing disease requires an understanding of genetic variables and genetic abnormalities.
The likelihood of having a kid with a birth defect, a developmental disability, or a condition like cancer or heart disease has been linked to several genetic abnormalities.
Since humans and chimpanzees share more than 92% of their DNA, this indicates that we are closely related and have a common ancestor. Genetics is the type of proof supporting this shared ancestry.
Thus, the correct option is A.

The mouth parts of a mosquito are in the shape of a needle, which allows it to pierce tissue and suck out fluids. What is the purpose of the structural adaptation?
A.to blend in with surroundings
B. To defend agianst predators
C. To move in the environment
D. To to botanical food resources
Answer:
D
Explanation:
The mosquito's mouth, also called a proboscis, isn't just one tiny spear. It's a sophisticated system of six thin, needlelike mouthparts that scientists call stylets, each of which pierces the skin, finds blood vessels and makes it easy for mosquitoes to suck blood. And these bugs know just where to bite.
When do the electron and molecular geometry of a molecule match?.
Electron and molecular geometry of a molecule matches when : The central atom has no lone pairs of electrons
Electron geometry vs molecular geometry
The electron geometry of an atom is the various arrangement of the electrons in an atom while the molecular geometry of an atom is the 3D structure of atoms in a given molecule.
For the electron and molecular geometry to be the same the central atom has to possess no lone pairs of electrons.
Hence we can conclude that Electron and molecular geometry of a molecule matches when : The central atom has no lone pairs of electrons.

1. What is some information about Cellular Respiration?
2. What is some information about Photosynthesis?
3. What are the connections between Photosynthesis and Cellular Respiration?
Answer:
1.cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
2.
Explanation:
Green leaves synthesize food woth the help of air, sunlight and water by a process called photosynthesis
3.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.
THIS FOLLOWING ANSWER IS ONLY FOR QUESTION ONE:
Cellular respiration is what cells do to break up sugars to get vitality they can utilize. Cellular respiration takes in food and employments it to create ATP, a chemical which the cell employments for energy. More often than not, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the vitality that cells have to be compelled to do work. When they do not get sufficient oxygen, the cells use anaerobic respiration, doesn’t require oxygen. In any case, this process produces lactic acid, and isn't as productive as when oxygen is utilized.
Aerobic breath, the method that does utilize oxygen, produces much more energy and doesn’t create lactic acid. It too produces carbon dioxide as a squander item, which at that point enters the circulatory system. The carbon dioxide is taken to the lungs, where it is traded for oxygen. The rearranged equation for aerobic cellular respiration is:
[tex]C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy (as ATP)[/tex]

The major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.
What is climate change?Climate change is caused by the increase of greenhouse gases in the atmosphere, primarily carbon dioxide from burning fossil fuels. This increase in greenhouse gases leads to global warming, which in turn causes changes in temperature and weather patterns around the world. These changes have significant impacts on ecosystems and can lead to the extinction of many species. Climate change can cause more frequent and severe extreme weather events such as droughts, floods, and hurricanes.
Hence, the major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.
