Which of the following statements accurately describes the process of dating Earth's history? a. Scientists use radiometric dating to determine the relative age of a new fossil.
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.

Answers

Radiometric dating and radioactive dating are two different names for the same method.

This method serves  to determine the absolute age of a fossil: the correct answer is C.

Relative dating and index fossil both serve to determine the relative age of the fossils.

Why is agriscience so concerned with the environment?

Answers

Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.

What is the role of agriscience in environment?

Agriculture can have major negative environmental effects, such as soil, water, and air pollution.

However, it can also have advantageous impacts, such as minimizing flood risks by utilizing particular farming methods or collecting greenhouse gases in crops and soils.

Because it deals with the growth of crops and the raising of animals for human and industrial use, agricultural science is extremely concerned with the environment.

Agriculture analyzes the environment to learn about its traits, attributes, and variations. Without it, agricultural experts wouldn't know where to raise animals or put their crops.

Answer:

Agric science is very concerned with the environment because it deals with the cultivation of crops and rearing of animals for man and industrial use.

Agric science studies the environment to know its characteristics, properties and its variations. Without this agricultural scientists would not know the best place to plant their crops or rear animals.

What is the importance of the mitochondria structure in cellular respiration

Answers

Mitochondria plays an important role in cellular respiration through the production of ATP, using chemical energy which is found in glucose and other nutrients.

What is Mitochondria?

Mitochondria are membrane-bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reactions. This chemical energy is stored in a small molecule produced by the mitochondria called adenosine triphosphate (ATP).

Mitochondria have many functions such as

1. Oxidative Phosphorylation

This process is used to produce cellular ATP

2. Important Roles in Ion Homeostasis

3. Supports Multiple Metabolic Pathways

4. Help with apoptosis and programmed cell death and ROS production and consumption.

The main role of mitochondria in cells is to perform cellular respiration which takes in nutrients and breaks them down and then turns it into energy. Cellular respiration occurs in both the matrix and the inner membrane of the mitochondria.

Thus, Mitochondria plays an important role in cellular respiration through the production of ATP, using chemical energy which is found in glucose and other nutrients.

The ocean contains many plants and protists that can make their own food. What do these organisms get by living near the surface that they cannot get in deep water? A. sunlight B. shelter C. food D. oxygen

Answers

Answer:

The correct answer is A. Sunlight.

Explanation:

The ocean contains many plants and protists that can make their food, such as phytoplankton. These organisms are photoautotrophs, which means that they need light to photosynthesize, otherwise they would not be able to produce primary production.  

Photosynthetic activity of marine organisms depends on luminous intensity, but solar light can only reach up to a certain depth in water, which is not much deeper than the surface. So every photoautotrophic organism must inhabit near the surface to get the necessary energy amount.

Each organism and species can live at different depth levels according to their needs, but all of them are restricted to the surface or near the surface because they need solar light.

The answer that i'd go with is A.Sunlight
Hope i helped

What major benefits do plants and mycorrhizal fungi receive from their symbiotic relationship? a. plants receive sugars, and fungi receive nitrogen.
b. plants receive micronutrients, and fungi receive sugars.
c. plants receive macronutrients, and fungi receive micronutrients.
d. plants receive nitrogen and phosphorus, and fungi receive sugars?

Answers

The correct answer could be both b: 'plants receive micronutrients, and fungi receive sugars' and d: 'plants receive nitrogen and phosphorus, and fungi receive sugars'. In this mutualistic association, plants provide a relatively constant supply of carbohydrates derived through photosynthesis. The fungi are able to mobilise soil minerals that are unavailable to the roots of the plants such as phosphate, nitrate and and micronutrients such as iron.
