How do convection currents cause the motion of tectonic plates??

Answers

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Answer:

These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

Black fur is dominant and white hair is recessive in rabbits. A white female has 2 white bunnies and 2 black bunnies. What was the genotype and phenotype of the father? You are not making baby bunnies so you need reasoning skills not a Punnett square.

Answers

The father would be dominant recessive. The mother is white so therefore her genotype would be recessive, bb . And the offspring are 50%, 50%. So therefore there has to be a Dominant gene present to form black offspring. But he can not be completely dominant or all the offspring would be black. So the fathers genotype would be Bb B=black b=white and his phenotype would be black.

How do you know if something is alive? Describe some of the characteristics of living things.

Answers

Answer:

We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:

Reproduction - to make more of the same organism

Sensitivity - the ability to detect and react to stimuli

Nutrition - eat and digest food.

Movement - the ability to change its position or location

Respire - to breathe / gas exchange

Excretion - get rid of toxic / materials in excess

All living things show the characteristics above.  

For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.

Answer:

To be alive organisms have to include all of the following:

- Made up of a cell or cells

- Has DNA

- Can reproduce

- Responds to the environment

- Grows and develops

- Exchanges energy

- Evolves

Explanation:

Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.

The majority of pesticides do not have a residual effect (i.e., not persistent; lose chemical activity) in the soil.

a) True

b) False

Answers

Answer:

B- False

Explanation:

Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Soil can be degraded and the community of organisms living in the soil can be damaged by the misuse or over use of pesticides. Some pesticides are more toxic to soil organisms than others.

Why must a forensic anthropologist be able to distinguish between antemortem and perimortem pathology

Answers

Answer: Antemortem describes injuries or pathologies inflicted on the victim before the death. Perimortem refers to any injury associated with the manner of death.

Explanation:

A foresen anthropologist is a person who is dedicated to identifying and studying skeletonized human remains and trying to determine markings on the bones that can elucidate the causes of death. In this way, the anthropologist seeks to learn about the events that occurred by studying the injuries and analyzing evidence left at the scene.

The term antemortem is used to describe injuries or pathologies on the victim before his or her death, which, however, have not caused the person's death. On the other hand, the term perimortem refers to injuries or pathologies associated with the manner of death. That is, it is necessary to distinguish between the two to determine the cause of death of the person. Not only has an antemortem injury or pathology not led to death, but it has no relationship to the event. And a perimortem injury or pathology is fatal, it must be focused on in order to clarify the facts and know how the person died.

Confusing an antemortem pathology with a perimortem one or vice versa, can lead to an erroneous diagnosis of the cause of death.

Oak tree and maple tree are  most likely to occupy similar niches in different ecosystem.

What is an ecosystem?

An ecosystem is defined as a system which comprises of all living organisms and  physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other for requirement of energy.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
