What’s the difference between field farm and factory farm

1 answer:

6 0

Answer: Industrialized agriculture is highly concentrated and mechanized, relying on chemical inputs like fertilizers, pesticides and non-therapeutic antibiotics. However, sustainable agriculture, which uses methods that protect the environment, public health, human communities and animal welfare, is gaining traction.

Discuss ecology for a discovery and hypothesis driven aspect.

cestrela7 [59]

Answer:

Ecology refers to the scientific study of the associations between the organisms and the surroundings in which they thrive. Humans have always been witnessing and learning about the organisms and their surroundings around them. They have acquired many insights and deduced hypothesis on the basis of their observations.

This is the aspect of discovery in the branch of ecology. Identically, there is an experimental scenario associated with the ecology that has been developed recently. This comprises formulating a hypothesis first and then examining it in the field or in the lab. Therefore, ecology utilizes the fundamental scientific procedure of hypothesis formulation and then examining and validating by the observations and experiments.

Which statement accurately describes tectonic plate movement? Tectonic plate movement can be prevented with planning. Tectonic p

ira [324]

Answer:

The correct answer is Tectonic plate movement is a long-term environmental change.

Explanation:

When tectonic plates in the earth started to move, this process helped the planet to evolve and to shape the continents as exist today.

Different investigation teams have discovered that plates move approximately 2.5 centimeters per year. This movement is the key to the evolution of life and the development of the planet. This slow process involves mountain formation, rocks exposure, and chemical reactions that could stabilize the temperature on the earth´s surface for millions of years. And this stable weather is essential for the evolution of life. Plates movement carries carbon inside and outside of the planet, regulating the amount of carbon dioxide in the atmosphere (greenhouse effect). In this way, it can regulate the temperature. This regulation influence in precipitations, chemical reactions that involve carbon release and minerals such as calcium, the water flow, volcanic eruptions, among other events. Plates tectonic is also responsible for life, as weathering and mineralization of the rocks release elements and nutrients that are necessary for the life of different organisms.

So, up to this point, we can say that tectonic plates movement can not be prevented with planning, it does cause environmental change by regulating temperature, and hence it affects organisms.

There are short term effects and long term effects provoked by tectonic plates movement. Earthquakes are examples of short term effects, while mountain formation, ocean formation and, clime regulation are examples of long term changes.

Plates tectonic movement is a very slow process, that might last many years. The Andes formation, for example, started approximately 200 years ago, and these mountains are still rising. The subduction process has not finished as the plates are still moving.

astra-53 [7]

Answer:

The values that most closely represent the expected number of Janice blonde-haired offspring is 252 individuals, option C.

Explanation:

Available data:

Two diallelic genes acting in a recessive epistatic manner to express hair color
Allele A is dominant over the allele a
Allele B is dominant over the allele b
A_B_ Cookie monster blue
aaB_ Elmo red
__bb Janice blonde

When talking about epistasis, we are referring to an interruption. These are interactions between genes located in different loci in the same chromosome. An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene. When the epistatic gene is recessive, the interaction is known as recessive epistasis.

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.

9/16 individuals are expected to be Cookie-monster blue-haired, A-B-

3/16 individuals are expected to be Elmo Red, aaB-

4/16 individuals are expected to be Janice blond, A-bb + aabb

16 ------------------------------------------- 1000 individuals

4 Janice blond individuals ---------- X = 250 individuals

So, 250 individuals are expected to be Janice blonde. The observed number might vary a little bit from this value. The values that most closely represent the expected number of Janice blonde-haired offspring is c = 252 individuals
