Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

How does the DNA sequence in a normal hemoglobin gene compare to a sickle cell hemoglobin gene?
ASAP
Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.
Explanation:
The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.
What is Sickle cell anemia?Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.
Symptoms of sickle cell anemia include infections, pain and fatigue.
Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

Light Reactions : ATP :: Calvin Cycle :
a. G3P
b. H2O
c. O2
d. H+
Answer:
a. G3P
Explanation:
Photosynthesis is the process by which plants synthesize their food from inorganic sources in the presence of light. The photosynthetic process occurs in two stages namely: light dependent stage (light reaction) and light independent stage (Calvin cycle).
The light stage primarily functions to synthesize ATP and NADPH products needed in the Calvin cycle to synthesize sugar (glucose). However, the CALVIN CYCLE produces a three-carbon compound called GLYCERALDEHYDE-3-PHOSPHATE (G-3-P) as one of the precursors of glucose.

Ethanol
Energy
Carbon dioxide
Carbon dioxide because During fermentation, carbon dioxide is produced and trapped as tiny pockets of air within the dough. This causes it to rise. During baking the carbon dioxide expands and causes the bread to rise further. The alcohol produced during fermentation evaporates during the bread baking process.

#SPJ5
The correct pairing of DNA bases is C with G, and A with T. Therefore option D is correct.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
In DNA, the bases always pair up in a specific way known as complementary base pairing. The bases adenine (A) and thymine (T) form a pair, and cytosine (C) and guanine (G) form a pair.
This pairing is based on the specific hydrogen bonding interactions between the bases:
Adenine (A) always pairs with thymine (T) through two hydrogen bonds.
Cytosine (C) always pairs with guanine (G) through three hydrogen bonds.
This specific pairing of bases is crucial for DNA replication and the accurate transmission of genetic information during cell division and protein synthesis.
The pairing of DNA bases: (D) C with G, and A with T. This pairing reflects the complementary base pairing rules observed in DNA.

In a cross Bb x Bb (B = Blue petals and b = pink petals), how many offspring will have the genotype Bb?
Answer:
2 offspring will have the genotype Bb.
Explanation:
Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb. In the top right box, the B on the top and the B on the side make the BB genotype. In the top left box, B and b make the first Bb genotype. The lower right box crosses B and b to make the second Bb genotype. The last box in the bottom right crosses b and b, resulting in the genotype bb. So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype. (I got this by combining the letters outside the punnet square in the box where the row and column meet) .
