If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?
Answer:
yy
Explanation:
it can only be yy because you need 2 recessive genes to show a recessive trait.
A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.
The possible genotype of the green offspring is yy, i.e., recessive one and will express only in absence of dominant allele.
What is genotype?In a broad sense, the word "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes.
In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
A genotype is a classification of the type of variant found at a specific location (i.e., a locus) in the genome.
Symbols can be used to represent it. For example, the letters BB, Bb, bb could be used to represent a specific variant in a gene.
In the given scenario, Y is dominant allele which will express in combination with y means the recessive one.
Thus, for expressing the green allele, it should be yy.

On February 21, a student observes that the Moon cannot be seen in the clear night sky. The date when the student is not able to see the Moon again is on March 21. The correct option is D.
What is the moon?The moon is the only natural satellite of the earth. It is white and gray and visible from the earth on nights only. It is the fifth-largest satellite in the solar system.
The moon has different phases seen from the earth because the moon revolves around the sun. The four phases have been named full moon, no moon, C moon, and half moon.
In 28 days, the moon is not visible for one day, then the other day it is visible and C-shaped. The student was seen on February 21.
21 + 27 day means 21 march.

Which of the following is true regarding glycolysis ?
Choose 1 answer.
A.) It requires glucose as a reactant.
B.) It produces 36 ATP.
C.) It occurs in the mitochondria.
D.) It is an aerobic process.
Answer:
I would have to say A
Explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. So we already know that it uses glucose because thats what its breaking down. Glycosis produces 2 ATP so B is wrong. Glycolysis happens in the cytoplasm so C is wrong. Finnaly aerobic is using free oxygen in the process of the reaction. However glycolysis uses no oxygen and is anaerobic.
Glycolysis requires glucose as a reactant.
• Glycolysis refers to a cytoplasmic pathway that dissociates glucose into the three-carbon compound and produces energy in the form of ATP.
• The process of glycolysis takes place in the cytoplasm.
• In the process, the net production of 2 ATPs takes place.
• It can be both anaerobic and aerobic process.
• The process of glycolysis completes in 10 steps, five of which are in the preparatory phase and the rest 5 are in the pay-off phase.
• The process of glycolysis is used by all the cells of the body to produce energy, and the final product of glycolysis is pyruvate.
Thus, correct answer is option A, that is, it requires glucose as a reactant.

Explanation:
A farmer is spraying his crops with a specific pesticide. He notices a drastic decrease in the insect population, so he uses the same pesticide the next year. This time, more insects survive. The next year, almost no insects are killed by the pesticide. Why is this happening?
Answer:
Probably insects developed resistance to the pesticide.
Explanation:
The term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to reach a certain effect on the insect population.
Insecticides might produce a genetic modification in the insects, leading them to survive under the effects of the chemical. Insects evolve with the capability of tolerating the poison dose that normally is used to destroy a normal population of plagues.
In the exposed example, the first time that the farmer sprayed the pesticide, the insect population decrease sharply. This means that the chemical affected them severely. The surviving individuals probably suffered a genetic modification and survived. They probably passed this modification to the following generations, which expressed it, and developed resistance to the pesticide.

These structures suggest that Dogs and humans are more closely related than snakes and humans.
Does snake have backbone?
Yes, snakes have a backbone. The backbone is made up of a series of bones called vertebrae, which are connected by ligaments and muscles. The vertebrae of a snake are unique because they are loosely connected, allowing the snake to move and bend in a wide variety of directions.
Dogs and humans are more closely related than snakes and humans because they both have vertebral columns, tails, and limbs while snakes only have a vertebral column and a tail. This suggests that a common ancestor shared these features with both dogs and humans, while the common ancestor of snakes did not possess these features.
Therefore, Dogs and humans are more closely related than snakes and humans is the correct answer.

Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates,
So the correct answer is D. Dogs, snakes, and humans share a common ancestor.
What is a common ancestor?
A common ancestor is a hypothetical organism that is ancestral to two or more different groups of organisms. In other words, a common ancestor is an organism that gave rise to two or more distinct lineages through evolutionary divergence. All organisms that share a common ancestor are said to be related, and their evolutionary relationships can be represented as a branching tree-like diagram called a phylogenetic tree. The concept of a common ancestor is fundamental to evolutionary biology, as it allows scientists to infer the evolutionary history and relationships between different groups of organisms.
Dogs, snakes, and humans share a common ancestor. The presence of a vertebral column in all three organisms suggests that they belong to the same group of vertebrates, but differences in tails and limbs suggest that their ancestors underwent evolutionary changes that led to these differences.
Therefore, options A and C are partially correct but do not capture the full picture, while option B is incorrect. The correct answer is D.

The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
