How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answers
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.

Amagnetwith alength of 10cmwasgiven to Meera and shewas told to break themagnetinto3 pieces.Before breaking the magnet had 1 north and 1 south pole. How many north and south poles will the magnets now havetotally in all the 3 broken pieces?
Answers
Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.

One side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA. What would be the complementary side’s bases? How many amino acids would that sequence code for?
Answers
Answer: The arrangement of these nitrogen bases contains the code for
genetic traits. These bases are arranged in a particular
sequence, such as TGCATTCA. The sequences of DNA can vary
from several hundred bases to a million or more bases.
Explanation: put this and my teacher said amazing
The complementary side’s bases if one side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA are: CCTGAAATGCGT.
What is the complementary sequence?Thus, the complementary nitrogen base sequence of GGTACTTACGCA is CCTGAAATGCGT. It is because the complementary nitrogen bases pair up: A always pairs with T, and C always pairs with G.
The sequence codes for 4 amino acids. Every three nitrogen bases code for one amino acid. So, since there are 12 nitrogen bases, the sequence codes for 12/3 = 4 amino acids.
To determine the number of amino acids coded by this sequence, first note that a codon consists of three nucleotide bases, and each codon corresponds to one amino acid. The sequence has 12 bases, so there are 4 codons: GGT, ACT, TAC, and GCA. Since each codon codes for one amino acid, this sequence would code for 4 amino acids.

Explain why parallax was a problem in proving the heliocentric model of the solar system.
Answers
Copernicus himself asserted that the absence of parallax meant that the stars were far beyond the planets. The failure of heliocentrists to detect it proved nothing, whereas a successful detection would be strong evidence for heliocentrism.
What is heliocentric model?The astronomical model in which the Earth as well as planets revolve around the Sun at the center of the universe is known as heliocentrism. Historically, heliocentrism was opposition to geocentrism, which centered on the Earth.
Galileo wanted to believe that his new invention, the astronomical telescope, could assist him in proving that the Sun was the center of our solar system and that Earth was only one of many planets orbiting our star.
Copernicus himself claimed that the lack of parallax indicated that the stars were far beyond the planets.
Failure to detect it by heliocentrists proved nothing, whereas successful detection would be strong evidence for heliocentrism.

One parent has the blood type A and the other blood type B. What are the genotypes of the parents if they produce children with only blood type AB?
Answers
Human blood type is determined by co-dominant alleles. An allele is one of several different forms of genetic information that is present in our DNA at a specific location on a specific chromosome. There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i).
Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
How are blood types related to the six genotypes?
A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.
A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
How are ABO alleles inherited by our children?
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 differnt combinations to consider when predicting the blood type of children. In the tables below, all 16 possible combinations are shown. If you know the blood type of the mother and father, the possible blood types for their children can be found.
What about the Rh factor? Can a father of blood type A+ have a child who is blood type A-?
The Rh factor genetic information is also inherited from our parents, but it is inherited independently of the ABO blood type alleles. There are 2 different alleles for the Rh factor known as Rh+ and Rh-. Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-.
Just like the ABO alleles, each biological parent donates one of their two Rh alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).

Describe the northern and southern hemisphere in terms of the distribution of the cryosphere
Answers
Answer:
The cryosphere is the portion of the Earth's surface where water is in solid form. It thus includes sea ice, lake ice and river-ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground. The snow cover has the largest extent, with a maximum area of more than 45 106 km2 (Table 1.1). Because of the present distribution of continents, land surfaces at high latitudes are much larger in the Northern Hemisphere than in the Southern Hemisphere. As a consequence, the large majority of the snow cover is located in the Northern Hemisphere (Figs. 1.15 and 1.16). The same is true for the freshwater ice that forms on rivers and lakes in winter. Both the snow cover and freshwater ice have a very strong seasonal cycle, as they nearly disappear in summer in both hemispheres (Table 1.1).

10. If one strand of DNA is
TCAAAGCTGC, what is the
complementary strand of DNA on the
other side?
Answers
Answer:
Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:
Brought to you by Sciencing
A deoxyribose sugar.
A phosphate group.
A nitrogenous base.
DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.
The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.
Complementary Definition (Biology)
In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
