Explanation:
Passive smoking may be banned in cars. Explain
how this may affect the number of cases of
lung cancer. [2]
Answer:
It would decrease the number of lung cancer cases
Explanation:
Many patients with lung cancer don't have to be actively smoking so they can actually get lung cancer by secondhand smoking(passive) especially in cars as the air is polluted and the car is like a small compartment with polluted air( lung cancer occurs over long periods of prolonged exposure especially in children)
Which of the following is the main purpose of using an anchored network of booms which funnel debris to a collection area?

What are the two forces that must balance out to maintain a state of isostasy?
Answer:
Isostasy is the rising or settling of a portion of the Earth's lithosphere that occurs when weight is removed or added in order to maintain equilibrium between buoyancy forces that push the lithosphere upward, and gravity forces that pull the lithosphere downward.

find the equation of the line joine points (2,2) and (-2,5).
Answer:
5x+4y-18=0.
Explanation:
1. the common view of the formula is:
[tex]\frac{x-x_1}{x_2-x_1} =\frac{y-y_1}{y_2-y_1};[/tex]
2. according to the formula above the required equation is:
[tex]\frac{x-2}{-2-2} =\frac{y-2}{5-2}; \ <=> \ 5x+4y-18=0.[/tex]
Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacterium-mediated plant transformation?
a. The Ti-plasmid used for this experiment must contain tumor-inducing genes.
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
c. The herbicide-resistance gene is cloned into a region outside of the T-DNA in the Ti-plasmid.
d. A guide RNA is used to transfer T-DNA from Agrobacterium to the plant cell.
e. The whole Ti-plasmid containing the herbicide-resistance gene is inserted into the maize genome after infection with Agrobacterium
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
Describe the process of aerobic respiration.
Answer:
Explanation:
Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. ...

Which of the following are differences between DNA and RNA? Mark all that apply.
a- DNA nucleotides include: Adenine, Cytosine, Guanine and Thymine
b- RNA nucleotides include: Adenine, Cytosine, Guanine and Uracil
c- DNA normally exists as double stranded
d- RNA normally exists as single stranded
e- RNA normally exists as double stranded
f- DNA normally exists as single stranded
g- The sugar in DNA is a ribose
h- The sugar in RNA is a deoxyribose
Answer:
The correct answer is - a, b, c, d, g and h.
Explanation:
DNA and RNA both are nucleic acids and have considered genetic materials. There are certain difference in these molecules such as-
Different sugars present in the nucleotide, Deoxyribose sugar in DNA and ribose sugar in RNA.
There are different nitrogenous bases also present as RNA has uracil instead of thymine.
DNA normally found in double-stranded while RNA exists in single-stranded.

What would you say is the most significant result of the technology revolution in archaeology ?
Answer:
Improvement of preservation techniques.
Explanation:
The most significant result of the technology revolution in archaeology is the improvement of preservation techniques used for archaeological sites. Modern technology also allows researchers to go to a site in order to find out the answers of additional questions. Modern archaeologists are fighting climate change, discovering how cultures evolved with the passage of time, and using technology to better understand human evolution.
3. Which of the following represents correctly paired nitrogen bases? (a) Adenine- Cytosine; (b) Cytosine-Thymine; (c) Guanine-Thymine; (d) Guanine-Cytosine.
Answer: The option that correctly represents paired nitrogen bases is D ( Guanine-Cytosine)
Explanation:
Deoxyribonucleic acid( DNA) is found in chromosomes which are located in the nucleus of cells. One of its main functions is to store the organism's hereditary traits and direct the day to day metabolic activities of each cell in the organism.
The DNA molecule consists of two strands that curve spirally to form a double helix structure which consists of:
--> phosphate,
--> A sugar called deoxyribose, and
--> Four nitrogenous bases—adenine, guanine, cytosine, and thymine
The four different NITROGEN BASES pair together in a way known as complementary pairing. ADENINE always pairs with THYMINE, and CYTOSINE always pairs with GUANINE.This is because of their molecular structures. Each base contains one or two nitrogen rings, which makes it long or short. It also has a sticky end of binding sites that connects with exactly one other base.
--> Adenine is long and has two binding sites.
--> Thymine is short and has two binding sites.
--> Guanine is long and has three binding sites.
--> Cytosine is short and has three binding sites.
From the above analysis, GUANINE can only bind to CYTOSINE.

What process allows a single cell to grow into a multi-cellular organism?
Answer:
Mitosis
Explanation:
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). As a cell constantly splits and the daughter cells constantly splits, it eventually creates a multi-cellular organism!
