Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems?
The expected outcome of crossing two tomato plants that are heterozygous for hairy stems is observing a phenotypic proportion of 3:1 plants (3 hair stem plants: 1 hairless stem plant).
What is dominance?Dominance in genetics is a phenomenon where the dominant alleles mask the recessive allele in heterozygous individuals.
Heterozygous individuals carry two different alleles for a given gene locus.Homo-zygous individuals carry the same allele or gene variant for a given gene locus.In conclusion, the expected outcome of crossing two tomato plants that are heterozygous for hairy stems is observing a phenotypic proportion of 3:1 plants (3 hair stem plants: 1 hairless stem plants).

What are CAM and C4 plants trying to eliminate from the Calvin cycle?
carbon dioxide
water
oxygen
Final answer:
CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.
Explanation:
CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.
CAM plants, such as cacti and succulents, close their stomata during the day to conserve water. At night, they take up CO2 and store it as organic acids, which are broken down during the day, releasing CO2 to enter the Calvin cycle.
C4 plants, like corn, have a unique leaf structure that allows them to keep their stomata open for CO2 capture while minimizing water loss. They use a specialized pathway to concentrate CO2 in bundle sheath cells, separating oxygen from the Calvin cycle and preventing photorespiration.
CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.
Explanation:CAM and C4 plants are both trying to eliminate oxygen from the Calvin cycle.
In CAM plants, stomata are closed during the day to minimize water loss, but they open at night to take up CO2. The CO2 is fixed by combining it with PEP to produce malic acid, which is stored in vacuoles. During the day, the malic acid is converted back into pyruvate and CO2, which enters the chloroplasts and joins the Calvin cycle.
In C4 plants, CO2 is rapidly transferred from mesophyll to bundle sheath cells. In the bundle sheath cell chloroplasts, malic acid is oxidized to pyruvate, releasing CO2. This CO2 then enters the Calvin cycle for rapid fixation.

tRNA molecules are ejected from their amino acid in which step of translation?
Answer:
The correct answer will be at elongation step of translation.
Explanation:
Translation is a process during which synthesis of proteins takes place inside a special organelle called ribosomes in cytoplasm or ER of the cell. It proceeds in three stages: Initiation, elongation and termination.
tRNA molecules are involved during elongation phase of the translation where they add amino acids to nascent protein chain.
tRNA gets charged with amino acids at its 3' end and becomes charged aminoacyl tRNAs which binds to A (aminoacyl) site of the ribosomes where it forms peptide bonds growing polypeptide chain. Then it binds to P (peptidyl) site of ribosomes where an initiation complex with free A site accepts tRNA after start codon chain elongation takes place. In last, they binds to E (exit) site of ribosomes where they gets dissociated from the ribosomes so that they can be recharged again with free amino acids.
Thus, during elongation phase they gets dissociated from the ribosomes.
identify a use for glucose in a plant that does not occur in animals
Glucose is used by plants to synthesize cellulose, the structural material in plant cell walls, which does not occur in animals as they cannot produce cellulose.
Explanation:One use for glucose in plants that does not occur in animals is in the synthesis of cellulose, which is the structural material of a plant's cell walls. Animals, including humans, are unable to synthesize cellulose because they lack the necessary enzymes to form the beta-glycosidic linkages that characterize this polysaccharide. Cellulose gives plants their rigid structure, allowing them to stand upright and form the necessary frameworks for leaves, stems, and roots. In contrast, animals must obtain cellulose indirectly by eating plants or plant products, and most cannot digest it, using it mainly for fiber.

How many cells are made in mitosis?
Mitosis produces two genetically identical daughter cells from one parent cell. This cell division process involves multiple stages to ensure accurate genetic replication and distribution. The resulting two cells are vital for growth and repair in organisms.
Mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell. During this process, the nucleus divides, ensuring that each daughter cell inherits an exact copy of the parent cell's chromosomes. Hence, in mitosis, you start with one cell and end up with two cells, each with a complete set of genetic material.
Stages of Mitosis
The process is divided into several stages: prophase, metaphase, anaphase, and telophase, followed by cytokinesis. By the end of telophase and cytokinesis, the original cell has divided into two identical cells.
These two newly formed cells are crucial for growth, healing, and various other functions in multicellular organisms. Each of these cells maintains the same number of chromosomes as the parent cell, ensuring genetic consistency.
In which specimen were cells first identified?
microorganism
cork bark
DNA
mitochondrion
The correct answer is:
cork bark
Explanation:
The cell was first discovered and described by Robert Hooke in 1665. He mentioned that it looked especially like cells or little rooms which friars occupied, in this way limiting the name. Nevertheless what Hooke really recognized as the dead cell dividers of plant cells (cork) as it bestowed up under the magnifying lens.

Since the expansion of international trade, Dutch elm disease and chestnut blight have nearly killed off the Dutch elm and chestnut trees in America. One might infer that these diseases were the result of _____.
introduced species
competition for space
poor tree husbandry
lack of pollinators
Answer:
The most appropriate answer would be introduced species.
Introduced or invasive species refers to the organism which is not native to that ecosystem or place and can cause harm to the environment, the economy as well as human health.
So, the expansion of international trade might result in the introduction of Dutch elm disease-causing Ascomycota fungi in America.
Another example may include the introduction of water hyacinth in India.
The concentration of a sugar is high inside a cell and slightly lower outside the cell. What is most likely to occur if the sugar molecules can cross the membrane?
a. sugar molecules move inside the cell membrane.
b. sugar molecules move toward the nucleus.
c. sugar molecules maintain their concentration gradient.
d. sugar molecules move outside of the membrane.
The right answer is d. sugar molecules move outside of the membrane.
The simple diffusion is the diffusion through the plasma membrane (in the direction of the strong concentrations towards the weak concentrations, until equilibrium concentrations on both sides of the membrane). In the case that we have, the most concentrated compartment in glucose (that is inside the cell) will let it escape and go to the extracellular compartments until reaching equal concentrations between the two compartments.
