A current that travels along the West Coast keeps temperatures along the coastline cooler than temperatures inland all year long.
England experiences warmer temperatures than other countries at the same latitude because of the warming effect of a surface current.

In watermelons, the gene for green fruit (G) is dominant to the gene for striped fruit, and the gene for round shape (R) is dominant to the gene for oval shape. Suppose a plant with genotype GGrr, is crossed with a plant with genotype ggRr. What would be the expected phenotypes among the offspring?
F. 100% green and oval.
G. 50% striped and round; 50% striped and oval.
H. 100 % green and round.
J. 50% green and oval; 50% green and round.
Answer:
It's J

It's a 50/50 chance as the both alleles are dominant
Plants have low energy needs as compared to animals. Explain.
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

A. Gregory Mendel
B. G. H. Hardy
C. William Bateson
D. Reginald Punnett
Answer:
a. Gregory Mendel
Explanation:
Gregory Mendel is the father of genetics
Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.
Therefore, Option A is correct

An unlabeled hierarchical diagram of various astronomical bodies is shown. The labels A, B, C and D can be used to represent the galaxy, Mars, universe, moon, and solar system.
Part 1: Which four astronomical bodies would you choose to represent the four labels in the diagram?
Part 2: Explain why the hierarchical level D is different from the rest.
Answer:
Part 1:
The four astronomical bodies one could choose to represent the 4 labels in the diagram are
A - universe
B - galaxy
C - solar system
D - Mars
The universe contains galaxies and galaxies holds solar systems which have planets like Mars
Part 2: D or a planet like Mars is unlike all their other astronomical bodies it does not have other astronomical bodies within it thus, its different from rest.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
