define dorsiventral leaf
A dorsiventral leaf, also known as a bifacial leaf, is a type of leaf structure characterized by having distinct upper and lower surfaces with different functions and structures.
The upper surface of a dorsiventral leaf is called the adaxial surface, while the lower surface is called the abaxial surface. The adaxial surface is usually dark green and is exposed to more sunlight, while the abaxial surface is typically lighter in color.
This structural asymmetry allows for efficient photosynthesis on the upper surface while minimizing water loss through stomata on the lower surface.
Dorsiventral leaves are commonly found in dicotyledonous plants and contribute to their overall shape and function in terms of light absorption, gas exchange, and transpiration.

Two genes control color in corn snakes as follows: O- B- snakes are brown, O- bb are orange, oo B- are black, and oo bb are albino. An orange snake was mated to a black snake, and a large number of F1progeny were obtained, all of which were brown. When the F1 snakes were mated to one another, they produced 100 brown offspring, 25 orange, 22 black, and 13 albino.a. What are the genotypes of the F1 snakes
Answer:
The correct answer is - OoBb
Explanation:
As it is given that:
O- B- snakes = brown
O- bb = orange
oo B = black
oo bb = albino
And here, the cross between an orange snake and black snake which means:
P0 : ooBB × OObb
offspring of f1 would be =
F1 : OoBb
self cross of f1 offsprings
F2 : OoBb × OoBb
Gametes OB Ob oB ob
OB OOBB OOBb OoBB OoBb
Ob OOBb OObb OoBb Oobb
oB OoBB OoBb ooBB ooBb
ob OoBb Oobb ooBb oobb

why is the moon invisible from earth during a new moon science
Answer:
Explanation:
During the New Moon the far side of the Moon is illuminated by the Sun, while the side that faces the Earth lies in darkness so the Moon is invisible. As the Moon follows its path from the New Moon position more and more of the Earth-facing side becomes illuminated resulting in the “waxing” phases.
A chest radiograph of an asymptomatic 37-year-old man showed a 3-cm nodule in the middle lobe of the right lung. The nodule was excised with a pulmonary wedge resection, and sectioning showed the nodule to be sharply circumscribed with a soft, white center. Culture of tissue from the nodule grew Mycobacterium tuberculosis. Which of the following pathologic processes has most likely occurred in this nodule? a. lipid acummulation b. liqufactive necrosis c. caseous necrosis d. coagulative necrosis e. gangreous necrosis f. apoptosis g. apoptosis h. fat necrosis
Answer:
caseous necrosis
Explanation:
The pathologic process that most likely occurred to this nodule would be caseous necrosis. This occurs at the time of death of a some cells but it is a very unique scenario in which the cell maintains a soft and white proteinaceous dead cell mass, just like in this scenario. This type of cell death usually occurs in lymph nodes but can occur in any cell in the body including in the lung.
How is energy stored when ADP is converted to ATP?
Answer:

Genomic imprinting may involve a single gene, a part of a chromosome, or a whole chromosome. Indicate if the following statements are true or false regarding this phenomenon
1. Genomic imprinting is permanent in the somatic cells of a given individual. _____________
2. Genomic imprinting is permanent and affects future generations. ____________
3. Methylation is the chemical change underlying genomic imprinting. _____________
4. If a gene is imprinted, the offspring can express both the maternal and paternal allele. _________
Answer:
1. True.
2. False.
3. True.
4. False.
Explanation:
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
1. True: Genomic imprinting is permanent in the somatic cells of a given individual.
2. False: Genomic imprinting is permanent and affects future generations. It does not affect future generations because generally it is expressed in a parent of origin specific form.
3. True: Methylation is the chemical change underlying genomic imprinting.
4. False: If a gene is imprinted, the offspring can express both the maternal and paternal allele. It is independent of Mendelian inheritance.

Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1
What is pollinization?
Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.
What are the Feminine reproductive structures?The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.What are the Masculine reproductive structures?The pollen grains, or male séx cells, are produced in the stamens.The stamen has an anther where the pollen is produced, and a filament that provides support.What is fertilization?Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.
During fertilization
1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.
2) Once in the stigma, the pollen grain germinates.
3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.
4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.
5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.
6) The zygote develops in the ovary.

Assuming a brain cell in which glucose is the sole energy source, indicate for each of the following substances whether you would expect a net flux across the membrane and if so, how many molecules will move in which direction per molecule of glucose catabolized.
- electrons
-pyruvate
-oxygen
-ATP
-ADP
-Acetyl CoA
-Glyceral-3-phosphate
-NADH
-FADH2
-Oxaloacetate
-Water
-Protons
Answer:
electrons inflow
pyurvate inflow
oxygen inflow
ATP Outflow
ADP Inflow
Acetyl CoA no net change
Gluceral-3-phosphate no net flow
NADF inflow
FADH2 outflow
Oxaloacetate no net flow
water outflow
proton outflow
Explanation:
Aerobic respiration is the process in which cell get oxygen from within. There is no inflow of oxygen and the movement is minimum. The membrane covering the cell releases the excess oxygen if the initial storage is more than the requirement. This is in the form of outflow in ATP.
