Scientists break down evolution into which two categories?
microevolution and macroevolution
macroevolution and genetic drift
microevolution and mass extinction
natural selection and macroevolution
Answer:
Option A, microevolution and macroevolution
Explanation:
Scientist have categorized evolution base on the time scale into following two categories
a) Macroevolution – These are the processes which take a long time to occur such as formation of a new species, extinction of any rare species etc, Also it affects a large mass of population or the entire population
b) Microevolution – In this, the processes of change take a short time and usually they impact only a certain set of species for a shorter time period.
Thus, option A is correct.
Answer:
A. Microevolution and Macroevolution
Explanation:
Scientists break evolution down into 2 parts: Micro and Macro evolution.
- Microevolution is evolution in a community, and it is very slow and gradual. For example, wolves overtime evolved into dogs, and over time, mosquitos became resistant to chemicals set out to kill them.
- Macroevolution is the type of evolution that refers to long, large changes in evolution over long periods of time and can lead to the creating of new species. For example, a dinosaur species evolves over time into a bird species.

Choose two genetic disorders and tell how they are inherited
1. Two examples of genetic disorders are CYSTIC FIBROSIS AND SICKLE CELL ANEMIA.
CYSTIC FIBROSIS
Cystic fibrosis is typically inherited when a defect occur in the CFTR gene of an individual. The CFTR gene is responsible for production of a protein that regulates the movement of water and salts out of the body cells. This gene does not perform optimally in people who have cystic fibrosis and this leads to the production of thick, sticky mucus and extremely salty sweat. Individuals who have this disease usually inherit two copies of the defective gene, one from the father and the other one from the mother.
2. SICKLE CELL ANEMIA
Sickle cell anemia is a genetic disorder of the blood, which is cause by inheritance of two copies of abnormal hemoglobin from parents. The hemoglobin is responsible for movement of oxygen all through the human circulatory system. The abnormal hemoglobin causes defective red blood cells, which can not move oxygen around efficiently. Thus, individuals with this disease do not usually get enough oxygen in their blood, this leads to fatigue and chronic pains plus several other negative medical conditions.
in which process do plants release oxygen?
A. Photosynthesis
B. Percolation
C. Transpiration
D. Evaporation

Which important biochemical process receives a supply of NAD+ ions from the fermentation process during anaerobic respiration
Answer:
Glycolysis is the process that receives a supply of NAD+ ions from the fermentation.
Explanation:
When cells need energy but there is no oxygen for aerobic respiration than anaerobic respiration takes place.
Glycolysis is a universal process that provides energy in the form of ATP molecules. Glycolysis requires two molecules of NAD+, which are reduced to NADH during glycolysis. Thus, the regeneration of NAD+ is necessary as if NAD+ is absent, glycolysis cannot be able to continue.
During anaerobic respiration (respiration in the absence of oxygen), fermentation takes place to regenerate NAD+ used in the process of glycolysis.

Which photosynthesis process can occur at night
The Calvin cycle
chemical reactions that take place in chloroplasts during photosynthesis
Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process. This is due to having the ability to open the stomata at this time, and conserve water due to cooler temperatures at night in order to tolerate the heat in the day.
Some antibiotics used to treat infections in humans are also used to treat chickens, but some groups oppose this practice. The overuse of the antibiotics will most likely influence the natural selection of which type of organisms?
Answer:
Bacteria resistant to the antibiotics
Explanation:
Overuse of antibiotics has been proven to increase the mutation rates of bacteria population. The increased mutation increase the chances of developing a strain of bacteria that is resistant to the antibiotic. This eventually renders the antibiotic ineffective hence opening up risk for a health epidemic catastrophe.
The overuse of antibiotics will most likely influence the natural selection of antibiotic-resistant bacteria. These bacteria evolve mechanisms that protect them from the effects of antibiotics, making standard treatments for bacterial infections less effective.
Antibiotics are used to treat bacterial infections by targeting specific parts of bacterial cells, which can lead to the death or inhibition of these cells without harming human cells. However, when antibiotics are overused – in humans or in livestock such as chickens – it can lead to the natural selection of bacteria that have acquired or mutated genes granting them resistance to these drugs. This process is similar to the evolution of pesticide resistance; only the individuals with genes conferring resistance survive and reproduce. Over time, a higher proportion of bacteria in the population can withstand the antibiotics originally designed to kill them. This is a major concern in public health and animal husbandry because it can lead to the spread of antibiotic-resistant infections, which are harder to treat and manage.
many species of moths will fly toward bright light which of the following describes this behavior?
A. The moths have become habituated to bright light
B. The moths are displaying classical conditioning\
C. The moths have used insight learning to respond to the light
D. The moths display an innate response to an external stimulus
I think that it is D, not 100% tho
Answer:
D. The moths display an innate response to an external stimulus
Explanation:
A stimulus is any change in internal or external conditions of organisms to which they respond. Here, bright light serves as external stimulus to which the moth species respond by flying towards it. This behaviour of moth species to fly towards bright light is present in them since birth, that is, it is an innate response.
What are two features that form through wind deposition?
sand dunes and loess deposits
Two features that form through wind deposition are sand dunes and loess deposits.
What are sand dunes?
Sand dunes are mounds or hills of sand that form as a result of wind action.When wind encounters an obstacle or a change in wind speed, it slows down, depositing sand grains that it carries. Over time, these deposited sand grains accumulate and form dunes. Sand dunes can have various shapes, such as crescent-shaped, linear, or complex and multi-lobed. They are commonly found in deserts and coastal areas.What are Loess deposits?
Loess is a type of fine-grained sediment composed mainly of silt-sized particles that are transported and deposited by the wind. It is typically formed from the accumulation of wind-blown dust and sediments derived from sources such as dried lake beds, river floodplains, or glacial deposits. Loess deposits can be extensive and cover large areas. They are usually unstratified and characterized by their fertile nature, making them valuable for agriculture. Loess landscapes often exhibit gentle slopes and distinct, easily eroded features.Therefore, both sand dunes and loess deposits are examples of landforms shaped by wind deposition processes.

Why is it important polar bears stay around
In the Arctic marine ecosystem, polar bears play a vital role. With polar bears gone, the ecosystem will be affected negatively and have a bad influence on other organisms.
Polar bears are vital components of the Arctic ecosystem, but they face a severe threat due to global warming.
The melting of sea ice reduces their ability to hunt seals, which are their primary source of food. The white fur of a polar bear is an adaptation that helps them blend in with their snowy environment, allowing them to approach prey undetected, a trait crucial for their survival in the Arctic biome.
Climate impacts like warming oceans are causing the sea ice to break up earlier, which endangers polar bear populations by decreasing their access to food and increasing the likelihood of cubs not reaching adulthood. The loss of polar bears would not only be a tragedy in itself but would also be indicative of the broader ecological imbalances affecting the Arctic region, which could have cascading effects on global biodiversity.
As the ice continues to melt, polar bears are forced to travel longer distances, sometimes resulting in drowning or inland migration in search of sustenance. Their overall population has declined by twenty percent in the past ten years, highlighting the urgency with which we need to address climate change to protect them and their habitat.

when an animal has a simple structure of only one cell, they get their nutrients from their environment. when animals have a more complex structure, you and infer that they are multicellular and they have a specialized way of breaking down their food. thus, meaning they can be herbivores, omnivores, or carnivores.
You can look at their anatomical structures to see what structures they use to digest said food. For instance, if you were to look at a skeleton and saw that the animal had strong, flat-topped teeth, one would assume they are plants because those strong molars are needed to chew the tissue of plants.

in all organisms some of the energy that is taken is
a. lost to environment I form of heat
b. lost to environment in chemical
c. lost to environment in solar
d. all is lost to environment
Answer:
the answer is a
Explanation:
Though heat benefits the organism in the form of warmth, it does not benefit the environment in any way
a light for example provides light so you can see, but the heat produced as a result has no beneficial purpose
In life processes within all organisms, energy is obtained and utilized, but some is invariably lost to the environment, predominantly as heat energy. This is explained by the second law of thermodynamics, which asserts that all energy transfers or transformations are never fully efficient.
Explanation:All organisms utilize energy for their metabolic activities, and during this process, some energy is inevitably lost into the environment. The second law of thermodynamics justifies why this energy dissipation happens. This principle underscores that not all energy transfers and transformations are completely efficient; some amount of energy is lost in a form that is typically unusable, mostly as heat energy.
To illustrate, during cellular metabolic reactions, some energy is lost as heat energy because of the conversion and usage of chemical energy in food. This phenomenon is essential for warm-blooded creatures, as the heat energy assists in maintaining our body temperature.
The release of energy into the environment can occur in several ways, such as through work done or as a chemical, but a significant portion is usually lost in the form of heat due to biochemical reactions. Accordingly, with respect to your question, the option 'a. lost to environment I (in) form of heat' would be the most accurate.
