Answer:

A

Explanation:

Answer:

1.  Igneous. 2. Unstable. 3. Constant. 4. Stable.

Explanation:

Geologists determine absolute age by comparing the amounts of radioactive and nonradioactive elements in igneous rock. The radioactive, or unstable elements decay into nonradioactive elements. Because this rate of decay is constant for each element, geologists can compare the amounts of stable and unstable elements to determine how much of the stable elements have formed over time.

Explanation:

The method used by geologists in calculating the precise or absolute age of a fossil is called radiometric dating. This calculation is done by measuring the amount of energy emitted by some radioactive elements present in the igneous rocks.

Each element with radioactive properties has a constant decay rate of its radiation, which is the amount of radioactivity that it loses over time. After the necessary time, radioactive or unstable elements become stable particles.

Since each element has a constant decay rate, the time that has elapsed since its formation can be estimated.

Although fossils are normally found in sedimentary rock strata -which do not contain radioactive elements- their precise age is calculated using radiometric dating of adjacent igneous rock strata.

Answer:

peripatric speciation

Explanation:

When small groups of individuals break off from the larger group and form a new species, this is called peripatric speciation

Answer:

The reason why it occurs is when the organism doesn't have the desirable traits it needs to survive.

Answer:

The answer is option B "Late summer and early fall storms"

Explanation:

less tropical storms form into Hurricanes. A few great ecological conditions should be available to allow Hurricane. To start with, warm sea waters of in any event 80 degrees Fahrenheit should stretch out to a profundity of 150 feet or more. Warm surface temperatures along are insufficient for typhoon development; there must be a plentiful profundity of warm water to give energy to the tempest. Second, the environment should cool quick enough from the surface upward to permit soggy air to keep on being precarious and convect. Layers of warm air over top stop or "cap" tropical improvement. At long last, there should be minimal vertical breeze shear, that is, change in wind speed, between the surface and the highest point of the lower atmosphere. Solid breezes over top forestall tropical Hurricane development.

The food of come from autotrophic plant to animal through food chain. The energy cycles between the air and soil and plants, animals, and microbes occur by food web.

A food web is defined as the cyclical event of energy transfer among different trophic level of organism.

The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers

Primary producers are the green autotrophic plants and capture some of the solar energy  and convert it into chemical energy by photosynthesis.

The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.

Primary consumers or herbivores feed on producers constitute  the second trophic level of the food web.

in third tropic level, Secondary consumers eat primary consumers where as  tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.

Answer:

B.) A process of Energy conversion that captures light energy and transforms it into chemical Energy.

Explanation:

Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.

Answer:

Whether or not a given isotope is radioactive is a characteristic of that particular isotope. Some isotopes are stable indefinitely, while others are radioactive and decay through a characteristic form of emission. As time passes, less and less of the radioactive isotope will be present, and the level of radioactivity decreases. An interesting and useful aspect of radioactive decay is half-life, which is the amount of time it takes for one-half of a radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by coTnditions and is independent of the initial amount of that isotope.

Consider the following example. Suppose we have 100.0 g of tritium (a radioactive isotope of hydrogen). It has a half-life of 12.3 y. After 12.3 y, half of the sample will have decayed from hydrogen-3 to helium-3 by emitting a beta particle, so that only 50.0 g of the original tritium remains. After another 12.3 y—making a total of 24.6 y—another half of the remaining tritium will have decayed, leaving 25.0 g of tritium. After another 12.3 y—now a total of 36.9 y—another half of the remaining tritium will have decayed, leaving 12.5 g. This sequence of events is illustrated in Figure 15.1 “Radioactive Decay”.

Answer:

Calculating the age of a skeleton can be done by looking at the number of fused bones (option 3).

Explanation:

The calculation of skeleton bone age takes into account the complete ossification of bones, which occurs at various stages of human development.

In childhood, the epiphyses or ends of long bones are not completely ossified but are formed by cartilage, due to the process of growth. When development is achieved, the growth nuclei and cartilage disappear.

Bone age is a reliable parameter for calculating chronological age, as they are quite approximate.

The other options are not correct because:

   1. The length of the femur is useful for calculating height.

   2. The shape of the pelvis helps to differentiate the sex.

   4. The color of the bones is not a useful parameter to calculate the age of the skeleton.

Answer:

They divide rapidly

Explanation:

Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.
