During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.
What are chromosomes?Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.
Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.
During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.
The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

Matthias Schleiden used a microscope to observe that the
parts of plants consist of cells. Theodor Schwann used a
microscope to observe that the parts of animals consist of
cells.
Which two statements did the work of Schleiden and Schwann add to the cell
theory?
A. All living things are made of one or more cells.
B. All cells come from other living cells.
C. Cells contain genetic material that consists of DNA.
D. The cell is the basic structural and functional unit of life.
Answer:
The work of Schleiden and Schwann provided to the Cell Theory the conclusions relating to that all living things are made of one or more cells and the cell is the basic structural and functional unit of life.
Explanation:
Matthias Schleiden was a German botanist who in 1937, while studying plant tissue under the microscope, observed that all plants are made up of cells.
In 1938, physiologist Theodor Schwann performed an experiment similar to Schleiden's, but using animal tissue, concluding that animals are made up of cells.
By bringing together the findings of both scientists, two important conclusions for Cell Theory were reached:
The cell is the structural and functional unit of all living beings. All living organisms are made up of one or more cells.Both conclusions are part of the cellular theory, as it is known today.
Regarding other options:
B. All cells come from other living cells was a conclusion provided by Rudolf Virchow.
C. Cells contain genetic material that consists of DNA is an argument that is not part of the cellular theory. In fact, the DNA would not be discovered until 1953.

Once amylase has broken down starch, can it break down another starch molecule?
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

A plant cell b/c it has chloroplast
Explanation:
Chloroplast absorbs sunlight also known as light energy used for the process of photosynthesis.
The observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.
PLANT CELL:
A plant is an organism whose cells contain organelles called chloroplast, which harbors chlorophyll pigment. This feature enables them perform photosynthesis; a process that plants use to synthesize their food.Plant cells are eukaryotic in nature i.e. they contain a membrane-bound nucleus in their cells. In addition to these organelles, plant cells also possess a cellulose-embedded cell wall that strengthens the cell.

7. What happens during mitosis?
(a) The nucleus of the cell divides.
(b) The cytoplasm of the cell divides.
(c) The cell divides.
(d) The DNA replicates.
Answer:
(c) The cell divides.
Mitosis is the process in which a cell divides.
Mitosis is one of the two types of cell division. The other type of cell division is Meiosis.
Meiosis takes place in reproductive cells and the cell is divided into two which is further divided into four by Meiosis-II
While in Mitosis the process is somewhat similar, the parent cell divides into two new cells and there is no further division and also the parent cell and the two daughter cell will be the exact same

When a trait is shown and at least one letter is upper case.
A) dominant
B) recessive
C) trait
D) allele
Answer:
maybe trait?
Explanation:
dunno lol
Answer:
When a trait is shown and at least one letter is upper case, it is a dominant allele (option A).
Explanation:
In genetics the presence of a dominant allele - represented by a capital letter - is sufficient to suppress a recessive allele, expressing the dominant trait in the phenotype.
Dominance is based on allelic combinations of the genotype, which are expressed in the phenotype for a given characteristic:
Two dominant alleles (AA) express the only possible trait, dominant.One dominant allele and one recessive allele (Aa) show a dominant phenotype, as the former suppresses the latter. It is a hybrid or heterozygous.Two recessive alleles (aa) show a phenotype with the recessive trait.The other options are not correct, because:
B) Recessive is the allele that is only expressed in the phenotype when there is a pair in the gene.
C) Trait is equivalent to a characteristic.
D) Allele represents the different ways in which a gene is expressed.
Orchids are flowering plants that dependent visa punishment a pol a population of orchids in a rain forest has reached its carrying capacity rainforest be population is a limiting factor in the orca population what will happen to the orchids caring capacity of the rainforest
Answer:
Explanation:
The question is incomplete below is the correct version of the question.
Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases? A. The carrying capacity will not change because it is a constant property of a species. B. The carrying capacity will not change because it is a constant property of an ecosystem. C. The carrying capacity will decrease because the level of the limiting factor decreases. D. The carrying capacity will increase because the level of the limiting factor decreases.
Answer :C. The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
The carrying capacity of a system is how much population an habitat can sustain depending on the available resources without leading to competition. This resources include food, water, space.
Since Rain forest bee is a limiting factor for orchid therefore Orchid population is dependent on the Rainforest bee's population so a decrease in the bee's population will lead to a decrease in the orchid population.
This will then lead us to a decrease in the carrying capacity of the system due reduction in the population of the limiting factor the bee because carrying capacity is population dependent.
