Explanation:
Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.

If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?A. Laboratory experiment.
B. Field experiment.
C. Natural experiment.
D. Reference experiment.
Answer:
A
Explanation:
The correct answer would laboratory experiment.
In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.
Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.
The correct option is, therefore, A.

When is genetic drift a major factor in evolution?
O A. When there is low gene flow
O B. When there is high selective pressure
O C. When there is sexual selection
O D. When there is female choice
Answer:look at pic
Explanation:
When there is high selective pressure is the major factor in evolution.
What is Genetic drift?Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Therefore, When there is high selective pressure is the major factor in evolution.

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.

Even though the idea of recycling materials and using them in other ways seems like a good idea, why is the idea of using recycled tires at playgrounds a concern for some scientists?
edge2021
Answer:
The idea of using recycle tires at playgrounds is a concern for some scientists because they contain carcinogenic substances.
Explanation:
Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.

The artery that will eventually subdivide to form the posterior cerebral arteries is the _____ artery.a) basilarb) external carotidc) maxillaryd) superficial temporale) nternal carotid
Answer:
a) basilar
Explanation:
The basilar artery is an artery whose function is to supply of blood to the brain and central nervous system, thereby transporting oxygenated blood to the brainstem, cerebellum, and occipital lobes for maintaining normal brain function. This artery is 3 to 4 mm in diameter. The basilar artery is formed from the confluence of two vertebral arteries inside the cranium at the level of the medulla. The posterior cerebral arteries are formed by the bifurcation of the basilar artery, and they supply oxygenated blood to the occipital lobes and posteromedial temporal lobes.
