Answer:

Our Sun is categorized as a G-type yellow-dwarf main sequence star.

Answer:

B. All parts of the Earth's surface get the sunlight atbthe assume angle and of the same intensity

C. The regions near the poles get the most-intense and most-direct sunlight

Note: Then model and options are found innthe attachment below.

Explanation:

Latitude is the distance north or south of the Equator. It’s measured in degrees, from 0° to 90°. The amount of sunlight received and hence, the temperature of a place varies with latitude. The higher the latitude of a place or region, the lower the temperature of that region or place will be.

The elliptical shape of the earth contributes to how the heat from the Sun is received by a place. At the Equator, the Sun’s rays are most direct and intense, hence, the temperature of regions around the equator is highest.

At higher latitudes which have more curved surfaces, the Sun’s rays are less direct. Thus, the temperature of a place decreases with increase in latitude due to the less-direct heating by the Sun.

At the poles, the Sun’s rays are least-direct and least-intense. Temperature is lowest at the poles. That is why polar regions are covered with ice.

From the model and the options given, options A and D are correct while options B and C are false.

Question

The question is incomplete. The complete question is as follows:

Review the Data Tables in Exercises 1 and 2. Compare the results of the Unknown for all  tests to the results for the various known samples to determine the identity of the  Unknown. Explain the identity of the Unknown using your experiment results in the  exercises to help explain and support your answer.

Answer:

According to the results, the unknown is a protein.

Explanation:

According to the results, the unknown is a protein, not a carbohydrate or lipid. When Biuret's reagent test is performed, it tested positive while the tests for sugar, starch, and lipid were negative proving that the unknown substance is the protien.

Answer:

energy passing through the water, causing it to move in a circular motion. When a wave encounters a surface object, the object appears to lurch forward and upward with the wave, but then falls down and back in an orbital rotation as the wave continues by, ending up in the same position as before the wave came by.

Explanation:

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. The gravitational pull of the sun and moon on the earth also causes waves.

Answer:

As an ecological community develops, it goes through a series of stages called ecological succession. The enduring community, in which specific and environmental changes are minimized, is called the climax community.

Explanation:

Succession is a process that generally begins after a significant alteration or extinction of an existing community. During succession, a community begins from a point where pioneer species colonize a new area. Pioneer species actively work to provide nutrients to soils and thus allow life to begin to form in them.During this time, there is widespread growth of these fast-growing species. If this new development is in an area that has never been settled before, this is called primary succession. If colonization occurs where an area has been so severely disturbed that the original community no longer exists, this is called secondary succession. Primary succession begins with the establishment of pioneer species such as lichens and mosses. These change the physico-chemical characteristics of the substrate. Later, small plants such as grasses, shrubs and then trees arrive, until culminating in a climax community dominated by certain species. The equilibrium that characterizes the climax community can be altered by climatic, ecological and evolutionary factors.

Answer:

B

Explanation:

All living beings are in fact descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth, according to modern evolutionary biology. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population.

Explanation:

The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system that involves the hypothalamus in the brain and the pituitary and thyroid glands. ... This system allows the body to maintain a constant level of thyroid hormones in the body.

option 1- type 1 are considered insulin dependent

Explanation:

the other options all describe type 2

Answer:

1. Type 1 diabetics are considered insulin-dependent diabetics.

Explanation:

Type 2 diabetes acquires later in life not Type 1.

Type 1 diabetes is thought to be caused by an autoimmune reaction (the body attacks itself by mistake) that destroys the cells in the pancreas that make insulin, called beta cells. This process can go on for months or years before any symptoms appear

Type 2 control with diet and exersize while as Type 1 is controlled by insulin.

He could use this knowledge to help breed his horses to the best that they can be.

The degree to which genetic variations among persons may adequately explain the variations in their attributes is known as heritability. Characteristics like height, eye color, and IQ are examples of traits, as are illnesses like schizophrenia and autism spectrum disorder.

Heritability, which is denoted by the statistic h2 in science, describes the proportion of a trait's variation that can be attributable to genetic variation.

An estimation of a trait's heritability is particular to one population in a particular setting, and it might alter over time as conditions change.

Estimates of heritability range from 0 to 1. A heritability close to zero means that environmental factors, with very little influence from genetics, account for almost all of the variation in a trait among individuals.

Therefore, He could use this knowledge to help breed his horses to the best that they can be.
