Answer:
Yes
Explanation:
DNA, which is the genetic material, is a double-stranded molecule i.e. possess two strands. Each strand is made up of a sequence of nucleotide base, which are complementary to one another. The complementary base pairing rule as proposed by Chargaff states that Adenine (A) base will always hydrogen pair with Thymine (T) base while Guanine base (G) will always pair with Cytosine (C) i.e. A-T, G-C.
For example, If the sequence of nucleotides of one strand was CTAGCGGATC, the sequence of nucleotide of the other strand will be GATCGCCTAG. Hence, based on this question, the information of the sequence of base on one strand can be used to determine the sequence of the second strand.
If the lionfish population keeps rising, what would be the possible effect on the trophic levels of
the ecosystem?
Answer:
As lionfish populations grow, they put additional stress on coral reefs. For example, lionfish eat herbivores, and herbivores eat algae from coral reefs. Without herbivores, algal growth goes unchecked, which can be detrimental to the health of coral reefs.
Explanation:
The lionfish are eating other consumers, so the native consumer populations are dwindling. This decrease can have a ripple effect. Larger predatory animals may not have enough food to eat because the native species are decreasing.

Some transcription signals are located thousands of base pairs upstream of the gene they regulate. How does the distant signal initiate transcription
Answer:
enhancer sequences bind to transcription factors to increase the likelihood of transcription
Explanation:
Enhancers are short DNA regions (50–1000 bp) that may be localized upstream and downstream from the transcription start sites of the gene. It has been shown that enhancers can be localized several kilobases (30-100 kb) either 5' or 3' of the gene. These sequences bind to proteins (generally transcription factors) in order to alter the 3D structure of the DNA, thereby increasing the likelihood of transcription.
HELP ASAP PLS!!!! Which option identifies the most likely the cause of injury in the following scenario?
Sarah, who just turned 70, broke her elbow playing ice hockey with the neighborhood woman's league.
O Since menopause, Sarah's levels of the hormone testosterone have increased
O Since menopause, Sarah's levels of the hormone estrogen have increased.
O Since menopause, Sarah's levels of the hormone testosterone have dropped.
O Since menopause, Sarah's levels of the hormone estrogen have dropped.
Answer: Since menopause, Sarah's levels of the hormone estrogen have dropped.
Explanation:
The most likely cause of injury in the following scenario is that because of the menopause, Sarah's levels of the hormone estrogen, which is also known as a female hormone, have dropped and because of that she is playing ice hockey with others and since she did not play it before, she broke her elbow.
She broke it because she was inexperienced with it and if she has played it before menopause she could not break it.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part c
Answer:
What the scientist is doing incorrectly is placing test tubes in a cabinet in disorderly form, without protective or biosafety equipment, having other tubes loose on the shelf, which can fall, break and spill their contents.
Explanation:
The image scientist is doing an incorrect procedure because
He is handling laboratory material without protection. He has messy tubes on the shelf of the cabinet, which can be chewed and broken, spilling their contents. He is not using a ladder to reach the highest spaces in the cabinet and place the tubes.What could they do to make their work in the lab safer?Use biosafety equipment to handle containers with chemical or biological substances.Keep the tubes in racks or tube holders to prevent them from falling accidentally.Place the tubes in an orderly manner, using a ladder to place the tubes at the top of the cabinet.Why is it important to follow these procedures?It is important to follow these procedures to protect his body from accidental spills, as well as to avoid breaking containers and contaminating the work space.

the number of two digit is equal to four times the sum of digits. if the product of digits is 8 .find the number.
Answer:
I think you are only intended to find
24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24
That works as well

Answer:
Schistosomiasis is a disease caused by infection with blood flukes of the geneticist Schistosomiasis. Transmission of, and exposure to, the parasite result from fecal or urinary contamination of freshwater containing intermediate host, snails, and dermal contact with the same water.
Explanation:
Snails can carry diseases such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis, and schistosomiasis. Be cautious when stepping into freshwater, because there may be snails in it. I recommend not picking up or touching snails.

This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

What type of cells reproduce by mitosis
In mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells, same number chromosomes.
What is chromosome ?
A chromosome is defined as a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

The tongue is an example of an organ that assists in the process of digestion. which of the following best describes the level of structural organization for organs like the tongue?
A. It is less complex than a tissue
B. It is more complex than an organ system
C. It is less complex than a cell
D. It is more complex than a tissue
Answer:
C
Explanation:
The level of structural organization for the tongue is that it is more complex than a tissue. So the correct option is D.
What is a tongue?
In most vertebrates, the tongue is a muscular organ on the floor of the mouth that may move in a variety of ways. It is extended and specialised in grabbing insect prey in some animals (like frogs).
While cats and certain other animals use their tongues as tools for grooming and cleaning, some reptiles' tongues serve largely as sensory organs.
The tongue is an essential auxiliary organ in chewing and swallowing, helps mammals create negative pressure in the oral canal to permit sucking, is a key carrier of taste receptors, and helps humans speak.
The mammalian tongue is formed of a complex of striated, intertwined muscles, fat, and glands, all coated in mucosal surfaces. Humans often have their front tongue ends and margins in contact with their teeth, which facilitates communication and swallowing.
Therefore the correct option is D.
