Can you help me i will give you a branlist
Answer:
It means Practice makes Perfect
Explanation:
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.

How will this mutation most likely affect the squirrel population?
If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. This is how a mutation will most likely affect the squirrel population.
Which of the following are the best sources of longer-term, stored energy for our bodies?
A. Monosaccharides
B. Disaccharides
C. Polysaccharides
The best source of longer-term energy storage for our bodies are Polysaccharides. Option C is correct.
Saccharides are sugar molecules. Among these molecules, some are shorter than others though all of them provide very similar functions to our bodies. Our bodies break down these sugars in order to obtain energy.
Due to the nature of everyday life, our bodies at times need a quick source of energy, as well as energy to be stored for later. This is where the difference in saccharides comes into play. Monosaccharides and Disaccharides are a source of quick energy, due to their being short molecules they can be broken with ease for quick use.
On the other hand, Polysaccharides are chains of sugar that can at times span into the thousands. These chains are later quickly broken up into monosaccharides at times of need. This characteristic makes them ideal for long-term storage of energy and is the reason that option C is correct.

Evan finds a rock. He scrapes it with his fingernail and leaves a scratch. His rock must be:
O a metamorphic rock
harder than feldspar
softer than diamond
made of more than one mineral
HELLP
The correct answer is C. Softer than diamond
Explanation:
Evan observation is related to the rock's hardness, which is usually measured on a scale from 1 to 10, in which 10 represents the hardest rock (diamond). In the case of the rock Evan found, the fact the rock can be scratched just using a fingernail shows the hardness of this rock is 2.5 or below because only minerals with this hardness can be scratched using the fingernail, while a higher hardness requires more complex tools.
Moreover, in this level of hardness, there are minerals such as gypsum or talc and these are softer than others such as feldspar with a hardness of 6 or diamond with a hardness of 10. In this context, it is safe to conclude this rock is softer than diamond. Also, hardness is not enough to determine if a rock contains two or more minerals or if it is metamorphic.

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.
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.

Autism is a neurological disorder thought to be caused by mutant alleles of one or more genes. Scientists had been wondering why the number of children diagnosed as autistic increased dramatically in a decade, from 1 in 500 in 2002 to 1 in 88 in 2012. Researchers now think that they might have found at least part of the answer: Men are fathering children at later and later ages. A paper published in the journal Nature in 2012 showed a correlation between paternal age and the incidence of autism; the age of the mother was not a factor. How does this observation provide a possible explanation for the apparent increase in the rate of autism?
Answer:
There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.
