Explanation:
There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:
Burning of fossil fuels increases the level of carbon dioxide.
Cleaning agricultural land increases the level of carbon dioxide.
The availability of nutrients in plants affects the synthesis of oxygen.
The intensity of the sunlight can increase or decrease the synthesis of oxygen.
Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.
The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.
An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.
A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

Answer:
1.In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
2.Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the mechanism of natural selection by explaining how the best-adapted individuals are better suited to their environment.

In a forest ecosystem, spotted owls make their homes in the cavities of dead trees. Thissame habitat is home to the rodents that the owls feed on. Human activities, such as logging,have caused the population of the spotted owl to decline. From this information, what statement BEST explains the relationship between humans and the spotted owl
Options are given in the comment section:
Answer:
The correct answer is - Humans have taken away resources needed by the owls, so there are fewer owls.
Explanation:
In this question, it is established that the trees are the habitat for the owls, and also these trees help in their food resources as these trees are habitat of rodents also.
By logging, humans destroy the habitat of both owls and rodents they feed on and important for their growth and survivability. Humans have caused the removal of required resources for the owls therefore, there are fewer owls.
which type of plant was important in establishing the transition from water to land and the dominance of gametophyte
Answer: Nonvascular plants
Explanation:
Non-vascular plants are the plants that do not have a vascular system that has a xylem and phloem but rather, they have simpler tissues which have specialized functions that are used in the internal transport of water.
The type of plant that was important in establishing the transition from water to land and the dominance of gametophyte is the non vascular plant.
An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where 1=smooth-yellow, 2=smooth-green, 3=wrinkled-yellow, and 4=wrinkled-green. Do the results make sense?
Answer:
No
Explanation:
The results of the phenotype do not make any sense in relation to the main aim of the experiment.
Smooth, wrinkled, yellow, green describe attributes relating to seed texture and flower colours in a result that simulates that of a plant breeding experiment, rather than a plant physiology experiment.
The determination of the effects of carbon dioxide deficiency in the soil on the phenotypes of peas is a physiological experiment. Hence, a result in the form of a plant breeding experiment would make not be relevant.
New fossil primates are recovered in a stratigraphic layer of volcanic ash that includes fossil molars of a pig species known to have become extinct about 30 million years ago. Identify the fossil dating methods that are appropriate to use in determining the age of the fossil primates. Correct Dating Methods inquizitive
Answer:
The correct dating methods will be:
radiopotassium datingbiostratigraphic datingExplanation:
The primate fossils presented in the question above must be submitted to the dating processes known as radiopotassium and biostratigraphic so that the age of these fossils can be determined as accurately as possible.
Radiopotassium dating is based on the half-life of potassium, which is equal to 40 years. The term half-life refers to the number of years it takes for half the number of atoms of the radioactive isotope to be destroyed. Thus, radiopotassium dating measures the amount of potassium present in a fossil and relates this amount to the half-life of potassium, thus being able to calculate the age of the fossil.
Biostratigraphic dating, on the other hand, allows the age of a fossil to be determined by being compared with the age of another fossil and the physical and structural composition that these fossils have.
Therefore, to determine the age of primate fossils, radiopotassium dating would first be used in some fossils. These would be used as a model during biostratigraphic dating, allowing confirmation of the age of other fossils.

THE BIG IDEA ALL LIVING THINGS SHARE COMMON TRAITS Activity 1: Lesson introduction
CONSIDER AND CONNECT
DIRECTIONS: After reading the lesson introduction below, complete the activity by answering the questions that follow.
Think about the last time you ate a bowl of cereal. Maybe it was this morning, or months but if you concentrate you will remember the experience. Close your eyes and get a mental picture of yourself eating and tasting the cereal. Describe in as much detail as possible what you remember about the last time you ate cereal. Include what type of cereal you ate as well as the dishes you used or the room in which you enjoyed your meal.
Most likely your response involved eating cereal in a bowl, and with a spoon.
1. How would your experience of eating cereal.
have been different if you would have used a plate instead of a bowl and a fork instead of a spoon?
2. Why do you think that we have different dishes and utensils to eat different foods?
In the same way that your kitchen uses different items, like pots, plates, or utensils, your body has different parts to perform different functions. The way a part looks often relates to what it does. For example I cannot bake a cake by putting it in the refrigerator because the refrigerator has parts that make it cold not hot! This idea that structure, or how something is made and looks, relates directly to its function, or the job that it does, is just one of the unifying themes of biology that you will learn about in this lesson. By understanding the basic principles of life and what it means to be "living" you will be able to relate complex concepts throughout all areas of biology. The unifying themes can help simplify these concepts keeping you focused and connected.
Answer:
1) We would not enjoy our breakfast. It just wouldn't be the same. The way a part looks often relates to what it does. For example soup is a liquid yet we do not drink soup from a water bottle.
2)The idea is that structure, or how something is made and looks, relates directly to its function. When we look at the various eateries in our kitchen we immediately know how it is served and the way it tastes.
When we look at the different utensils in our kitchen, we immediately understand their function.

Species that compete for the same resources often switch to either use different resources or find ways to reduce competition. Why is this often true
Answer:
The correct answer is - to increase their survivability and reproductivity in the species.
Explanation:
Competition is the result of an interaction between two or more species or populations where both need or depends on the same limited resources that is utilized and protected by both and due to this one individual reduces the survival or reproduction of another individual.
In order to survive and reproduce their numbers species have to find other resources to feed or utilize or have to find new ways as if they did not adapt as per the changes they will be left very few or extinct.

A cloned mammal is made by removing the DNA from the unfertilized egg of an egg donor, replacing it with DNA from a cell of a mature animal, and then implanting that cell into the uterus of a surrogate mother. The cell then divides and behaves as if it were a regular embryo. Answer the following question(s) regarding a clone.Of whom is the baby a clone?
Answer:
The mature animal
Explanation:
The baby would be a clone of the mature animal whose DNA was placed in the unfertilized egg before being implanted into the uterus of a surrogate mother.
The DNA of the egg donor has been removed and replaced with the DNA of the mature animal. The surrogate mother is just a mere carrier and has no biological relationship with the clone. The only organism with biological relationship with the clone would be the one that donates its DNA, which in this case is the mature animal.

When calcium levels in the blood are too low, the body releases a hormone that removes calcium from the bones. A person who suffers from a certain type of thyroid disease will often have low blood calcium and brittle bones because the body is taking the calcium from the bones. The afflicted person will typically see an endocrinologist, who studies hormones, and an orthopedist, who studies bones. What do these two doctors have in common
Answer:
They both would need to check the calcium levels
Explanation:
The two doctors would both need to check the calcium levels of the patient.
While the endocrinologist would need to check the calcium level in the blood, the orthopedist would have to check the calcium level in the bones of the patient.
Most endocrine disorders are caused by abnormal calcium levels in the blood while the bones are largely made of calcium. Hence, both doctors would usually need to work with the calcium levels in the blood and bones respectively.
