Answer:

c

Explanation:

Answer:

True!

Explanation:

Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.

Clinical manifestation that is indicative of fluid and electrolyte imbalance associated with parathyroidectomy is : hypocalcemia.

Parathyroid glands are responsible for regulating the body's calcium and phosphate levels. In parathyroidectomy, one or more of these glands may be removed, leading to decrease in the production of parathyroid hormone (PTH) and disruption of body's calcium and phosphate balance.

Hypocalcemia, or low levels of calcium in the blood, is a common complication of parathyroidectomy. This can lead to symptoms like muscle cramps, spasms, and weakness and tingling or numbness in the fingers, toes, and lips. Other symptoms  are fatigue, irritability, and depression.

The correct answer is b. tRNA (transfer RNA) carries amino acids to ribosomes.

tRNA molecules play a crucial role in protein synthesis by carrying amino acids to the ribosomes, where protein synthesis occurs. Each tRNA molecule is specific to a particular amino acid. On one end, tRNA has an anticodon sequence that is complementary to the codon sequence on mRNA (messenger RNA). On the other end, tRNA carries and binds to the specific amino acid corresponding to its anticodon.

During translation, the process of protein synthesis, the mRNA sequence is read by the ribosomes, and tRNA molecules bring the appropriate amino acids to the ribosomes based on the codon-anticodon pairing. The ribosome catalyzes the formation of peptide bonds between the amino acids, resulting in the synthesis of a polypeptide chain.

mRNA (a) carries the genetic information from DNA to the ribosomes, providing the template for protein synthesis. rRNA (c) is a component of the ribosomes themselves and plays a structural role in facilitating protein synthesis. Proteins (d) are the final product of protein synthesis, and they do not directly carry amino acids to the ribosomes.

The observed phenotypic ratios (220:210:231:239) closely match the expected 1:1:1:1 ratio, suggesting that the two genes for stem color and petal length are likely unlinked.

The observed number of offspring (220, 210, 231, 239) closely aligns with the expected ratio of 1:1:1:1, indicating that the two genes are likely unlinked. This suggests that the genes for stem color (A/a) and flower petal length (B/b) assort independently during gamete formation.

If the genes were linked and located close together on the same chromosome, the expected ratio of offspring phenotypes would not be equal. The fact that the observed ratios match the expected ratios supports the hypothesis of independent assortment and suggests that the genes for stem color and flower petal length are located on different chromosomes or are far apart on the same chromosome, allowing for recombination events to occur between them.

The allele for brown eyes (B) is dominant in terms of eye color, while the allele for blue eyes (b) is recessive. Brown eyes are the result of having dominant alleles (BB) from both parents. The answer is only b.

Simple dominance is an inheritance pattern in which heterozygotes exhibit the dominant phenotype and one allele covers up another for a single gene. Since the phenotype can only be expressed by one allele, it is very likely that the offspring will also have a dominant trait if both parents have it.

From a wide perspective, the expression "genotype" alludes to the hereditary cosmetics of a living being; To put it another way, it describes every gene in an organism. In a more narrow sense, the term can be used to describe an organism's alleles or variant forms of a gene.

A capital letter (A opposed to A) indicates a dominant allele. Because each parent gives off one allele, the following combinations are possible: A, A, and aa The dominant trait will be exhibited phenotypically in offspring with genotypes of AA or Aa, whereas individuals with genotypes of aa will exhibit the recessive trait.

Land plants no longer required water as a medium for reproduction with the evolution of seeds and pollen. Seeds and pollen are specialized structures that allow plants to reproduce without the need for water.

This development has allowed plants to colonize a variety of habitats on land, including arid environments, where water is scarce. Land plants evolved from aquatic ancestors, and the earliest land plants likely required water for reproduction. However, as plants adapted to life on land, they developed structures that allowed them to reproduce without water. Fruits and roots are important structures for land plants, but they are not directly involved in reproduction.

Flowers and leaves are also important for land plants, but they evolved after seeds and pollen and are not required for reproduction in all plant species. Cell walls and rhizoids are important adaptations for land plants, but they are not directly related to reproduction. Lignified stems are important for structural support in land plants, but they are not directly involved in reproduction.

Therefore, the correct answer is 5 seeds and pollen.

Based on the given information and assuming the expected survival rates remain the same, it is expected that approximately 77 plants will be in age class 2 in 12 months.

To determine the number of plants in age class 2 in 12 months, we need to calculate the number of plants surviving from age class 1 to age class 2 and subtract any plants that would have died.

From the given information, there are 347 plants in age class 1, and the expected survival rate from age class 1 to age class 2 is S1 = 0.6. Therefore, the number of plants expected to survive from age class 1 to age class 2 is 347 * 0.6 = 208.2.

However, we also need to consider the expected mortality rate from age class 2. The survival rate from age class 2 to age class 3 is not given, but we can assume it to be S2 = 0.8, which means that 20% of plants in age class 2 will not survive to age class 3.

Thus, the number of plants expected to be in age class 2 in 12 months is 208.2 * (1 - 0.2) = 166.56, which can be approximated to 166 or 167 plants.

Therefore, approximately 77 plants will be in age class 2 in 12 months, assuming the expected survival rates remain the same.

The Gram stain is a common laboratory technique used to differentiate bacteria into two groups based on their cell wall properties. The procedure involves applying a series of reagents to bacterial cells that have been fixed onto a slide.

The reagents include crystal violet, iodine, alcohol, and safranin. In this problem, we are asked to determine the proper sequence of reagents used in the Gram stain procedure.

The proper sequence of reagents in the Gram stain procedure is as follows:

Crystal violet - this is the primary stain that is used to stain all the cells on the slide. It is a purple dye that binds to the peptidoglycan layer of the bacterial cell wall.

Iodine - this is a mordant that is used to enhance the binding of the crystal violet to the cell wall.

Alcohol - this is a decolorizing agent that removes the crystal violet stain from some types of bacteria that have a thin peptidoglycan layer in their cell wall. These bacteria are called Gram-negative bacteria.

Safranin - this is a counterstain that is used to stain the Gram-negative bacteria that were decolorized by the alcohol. It is a pink dye that stains the cytoplasm of the bacterial cells.
