Somatic stem cells are extracted from _____
A. An Egg
B. An Embryo
C. Developed Organs
D. A blastocyst
Answer:
A. an egg
Explanation:
The process of somatic cell nuclear transplant involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT (Somatic Cell Nuclear Transfer) experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation.
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.
Explanation:
This may help you out! :)

How are xylem fibers different from xylem parenchymav
Answer: Xylem fibers and xylem parenchyma are the elements of the xylem which is a vascular tissue in plants.
Explanation:
Xylem fibers are dead cells whereas the xylem parenchyma are living cells.
Xylem fibers are responsible for providing structural support to the entire structure of xylem whereas the xylem parenchyma is involved in conducting of water and minerals.
In xylem fibers the lignin is present whereas it is absent in xylem parenchyma.

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.

Bacteria and fungal spores can only contribute to indoor air pollution.
a/True
b/False
Answer:
The correct answer is - b. false.
Explanation:
Air pollution refers to small harmful substances or particles that get into the air and cause harmful effects such as breathing difficulty and disease associated with breathing. These particles can be chemicals, gases, dust, or biological pathogens and allergens such as bacteria and fungal spores.
Air pollution can be indoor air pollution or outdoor pollution, biological pathogen and allergen present more in indoor setting or system but they do not contribute only to indoor air pollution but all.

1. What is the role of sanitation and snails in maintaining
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.
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

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.

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.
