Answer:

Tectonic plate movements

Answer:

Neutrons.

Explanation:

Two atoms which are isotopes of one another must have a different number of neutrons.

Isotopes are defined as atoms of the same element which have the same numbers of protons i.e. atomic number remains the same but has different numbers of neutrons. It is observed that they have the same chemical properties due to the same electronic configuration but physical properties differ.

Answer:

to study the movement of continental plates beneath Earth's surface

Explanation:

Earth scientists study infrared as the thermal emission (or heat) from our planet. ... Instruments onboard Earth-observing satellites can sense this emitted infrared radiation and use the resulting measurements to study changes in land and sea surface temperatures.

Scientists use satellites in space to monitor and record the infrared radiation given off by Earth to study the difference between the temperatures at Earth's poles. Hence, option B is correct.

A satellite is a body that orbits a planet, star, or moon. For instance, the fact that Earth orbits the sun makes it a satellite. The moon is a satellite as well because it revolves around Earth. The term "satellite" typically refers to a device that is launched into space and orbits the Earth or another celestial body.

There are a large number of satellites in use. They serve a variety of functions, including the Global Positioning System, amateur radio, television transmission, and weather forecasting. In order to conduct studies and acquire data, they also employ telescopes to view outward at the solar system.

Scientists use satellites in space to monitor and record the infrared radiation given off by Earth to find out the climate of the certain continent. Hence, option B is correct.

They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent.

Answer:  Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.

Answer:

C. Structure and Function

Explanation:

The reason as to why it is C is because, Structure means construct or arrange according to a plan; give a pattern or organization to, to put it more simple, the way something is built to help the way it functions. So for example, the structure of a hair brush is built to pull out the tangles, why would I use it on feet? It's not structured the way it will help function my feet. Function means, work or operate in a proper or particular way. Example: "bridges perform the function of providing access across water" Basketball shoes are "STRUCTURED" in a way it'll help the basketball player play better. You wouldn't wear boots to a basketball game because boots are structured in order to help the human feet get through the snow. Basketball shoes are structured in order to help it function so that the basketball player can move around freely on the court and play freely.

Answer:

contact with bacteria answer is C

A person can develop a mold allergy through inhaling, touching, or coming into contact with mold or mold spores, hence option B is correct.

Similar to other allergic reactions, symptoms of a mold allergy are brought on by an abnormally sensitive immune response. Your body creates allergy-inducing antibodies to attack microscopic, airborne mold spores because it perceives them as alien intruders.

Local symptoms (symptoms that only affect one part of your body), such as a rash or hives, itching, watery or red eyes, hay fever, and runny nose, are examples of mild responses.

Molds can make persons with established allergies experience asthma symptoms such as coughing, wheezing, or shortness of breath, hence option B is correct.

Answer:

Re-producing sexually will allow the sea anemones to give their offspring a more diverse gene pool and can mitigate the risks of a genetic disorder being spread to the offspring because the bad gene has a higher chance become recessive if the gene of the anemone it mates with is more dominant (meaning it wouldn't allow the "bad" gene to show in the offspring) whereas otherwise, the offspring would have the same issues the mother did (assuming it had a bad gene to begin with).

Answer:

1. Convections

Convections propelled transatlantic trade when sailing was the only option for sea travel. The correct option is 1.

Convection is a method of moving heat that is also known as a heat transfer mechanism.

When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.

Heat transfer between objects occurs through direct contact in conduction. Heat transfer occurs within the fluid during convection.

Heat transfer in radiation occurs via electromagnetic waves rather than particles. Heat transfer occurs as a result of temperature differences.

The trade winds, also known as easterlies, are the permanent east-to-west winds that blow in the Earth's equatorial region. When sailing was the only option for sea travel, convections propelled transatlantic trade.

Thus, the correct option is 1.

Answer:

Whats your question?

Explanation:

Answer:

1) aa- affected

2) Aa- unaffected carrier

3) aa- affected

4) aa- affected

5) Aa - unaffected carrier

6) Aa- unaffected carrier

7) aa- affected

8) aa- affected

9) Aa- unaffected carrier

10) aa- affected

11) Aa- unaffected carrier.

This trait is recessive.

The F1 generation has a 50/50 chance of having unaffected offspring.

Explanation:

1) Given

2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier

3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)

4) They are also shaded in, so they have to have the trait

5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

6) Same reasoning as #5

7) This is shaded in, the box has to have the trait

8) Shaded in = has the trait/affected

9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

10) Shaded in = has the trait/affected

11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.

If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.
