Q: What is the structure in a diploid sporophyte that undergoes meiosis to form haploid spores? Read this paragraph and choose the correct option from the provided answers: A general plant life cycle is represented by the diagram in Figure below . From the figure, you can see that the diploid sporophyte has a structure called a sporangium (plural, sporangia) that undergoes meiosis to form haploid spores. A spore develops into a haploid gametophyte. The gametophyte has male or female reproductive organs that undergo mitosis to form haploid gametes (sperm or eggs). Fertilization of gametes produces a diploid zygote. The zygote grows and develops into a mature sporophyte, and the cycle repeats. Choices: - hymenium - dikaryotic - hyphae - sporangium A:
(Answer)
sporangium

Ques: Q: In science, coefficients are used to balance what kind of equations? Read this paragraph and choose the correct option from the provided answers: Equations in chemistry must balance. There must be the same number of each type of atom in the products as there is in the reactants. Coefficients are used to balance chemical equations. They show how many atoms or molecules of a substance are involved in a reaction. Choices: - liquid - isolated - mineral - chemical A:
Ans: chemical

Q: Blood helps maintain homeostasis by stabilizing ph, temperature, osmotic pressure, and by eliminating this? Read this paragraph and choose the correct option from the provided answers: The Role of Blood in the Body Blood, like the human blood illustrated in Figure 40.5 is important for regulation of the body's systems and homeostasis. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss and transporting the disease-fighting agents or white blood cells to sites of infection. Choices: - toxins - acid - water - excess heat A:
(A).
excess heat

Ques:Q: What is the main difference between prokaryotic or eukaryotic cells ? Read this paragraph and choose the correct option from the provided answers: The answer depends on if the cell is prokaryotic or eukaryotic. The main difference between the two types of cells is the presence of a nucleus. And in eukaryotic cells, DNA lives in the nucleus. Choices: - the type of metabolic waste - the presence of cell walls - the presence of a Golgi Apparatus - the presence of a nucleus A:

Ans:the presence of a nucleus

Ques:Q: Changes in the number of what can lead to disorders like down syndrome? Read this paragraph and choose the correct option from the provided answers: Changes in chromosome number can lead to disorders like Down syndrome. Choices: - prokaryotes - dna - genes - chromosomes A:

Ans:
chromosomes
