Answer:
In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms
Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.
Explanation:
Water is said to be a molecule made of oxygen and hydrogen atoms. There is a partial negative and positive charge at the poles of water due to hydrogen bonds, and electronegativity.
What are hydrogen bonds?Hydrogen bonds are defined as weak chemical bonds and interactions that result from the electrostatic attraction between the electronegative atom and the proton. These bonds are formed by dipole-dipole interactions.
Oxygen atoms in the water molecule are highly electronegative whereas the hydrogen atom of the water molecules is proton donors. This results in the formation of hydrogen bonds between the oxygen atom of one molecule and the hydrogen atom of the other molecules.
The electron sharing between the hydrogen and the oxygen atom tends to be unequal resulting in bonds being slightly towards the oxygen atom due to its electronegative nature. This results in the formation of partial positive and negative charges.
Therefore, hydrogen bonding results in slight positive and negative charges.

Read the following claim. Life on Earth could not exist without decomposers. What evidence from the article supports this claim? Explain why the evidence supports this claim.
Answer:
Explanation:
It's hard to distinguish facts/ evidence from the article with only the statement ' Life on earth could not exist without decomposers', but taking that into consideration, it's best if you breakdown the information so you properly understand what it means.
Life on earth - refers to evolution of life on earth such as single celled organisms, eukaryotes, prokaryotes, bacteria and so on
could not exist - refers to the inability of it being there, it's presence is basically there/ not there
decomposers - is an organism that breaks down organic materials from dead organisms to obtain energy such as fungi, bacteria, worms and so forth.
You basically need to relate all the information you find in the 'article' to the statement they have made and which i have broken down for you above.

A water strider sits on the surface of a pond. This occurs because
Answer:
their legs contain specialized hairs that are able to repel the water and to capture the air
Explanation:
The water strider is one of the most common aquatic insects. Water striders can sit on the water surface due to they have specialized hydrophobic water-repelling hairs in their legs that allow them to use the surface tension of water in order to distribute the weight. Thus, the hairs in the legs of these insects enable them to float and move on the water surface.

Where are there typically more ecological hotspots?
Answer:
There are currently 36 recognized biodiversity hotspots. These are Earth's most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as "endemic" species). The Andes Mountains Tropical Hotspot is the world's most diverse hotspot. About one-sixth of all plant species in the world live in this region. The New Zealand archipelago is another hotspot.

Why don't we have a genome sequenced from Homo erectus?
(a) There isn't enough research funding to pay for it.
(b) DNA degrades over time and the fossils are too old.
(c) H. erectus DNA is too similar to ours to prevent contamination.
(d) No H. erectus fossils have been found in Germany, which is where the lab is located.
(e) None of the above; we do have a sequenced genome of H. erectus.
Answer: Homo erectus DNA is too similar to ours to prevent contamination.
Explanation:
Homo erectus fossils are known as the oldest form of early humans that had human like body structure with shorter arms and elongated legs and shorter arms. These features gave them the ability to walk and also run long distances.
The reason that we do not have a genome sequenced from Homo erectus is that their DNA is too similar to ours to prevent contamination. There are enough fund which could have been used to carry out the research but their similarities to human beings has been the source of concern.

Driving from Maine to Florida, you observe that squirrels living in the southeastern United States are much thinner than squirrels living in the northeastern part of the country. You tell your friend that you have a theory that squirrels living in the northeast have greater fat reserves for the winter months when food is scarce. Which of the statements are true? Select all that apply.
Answer:
See the options and the answer below
Explanation:
The available options to the question are:
Your statement is a valid scientific theory. Your statement uses the word "theory" in a non-scientific, colloquial way. Your statement is a hypothesis rather than a scientific theory. Your statement is not a theory but a fact.The correct answer would be that:
the statement uses the word 'theory' in a non-scientific, colloquial way. the statement is a hypothesis rather than a scientific theory.A hypothesis is a generalized statement with little or no experimental test. When a hypothesis is tested using a suitable experiment (s), it can either become valid or invalid. In order words, hypotheses are falsifiable. A theory on the other hand is a hypothesis that has been tested several times by independent researchers and found to be true.
In the illustration, the statement made concerning the squirrels is based purely on guess and not on fact. The use of the word 'theory' in the statement is totally unscientific. Only suitable experiments can prove or disprove the statement.
The correct options are 2 and 3.

Compare pure water and coffee. Their pH differs by approximately
Answer:
They differ by two positions in the pH scale.
Explanation:
Hello,
In this case, since coffee has an pH of about 5 which is slightly acidic and water has a pH of 7, their pH differs by 2 approximately:
[tex]\Delta pH=pH_{water}-pH_{coffee}=7-5=2[/tex]
Such acidity in the coffee is caused by the presence of the well-known chlorogenic acid which is besides helpful for us towards reducing the degree of tiredness we eventually acquire along the day.

Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Hello. This question is incomplete. The full question is:
A tRNA anticodon is 5' GAA 3'.
Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Answer:
a) 5' UUC 3'
Explanation:
Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.
As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.
These bass are organized into codons, which are a set formed by 3 of these bases.
The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.
In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.
