When a glacier melts, the ocean level rises therefore causing flooding and creating alien environments for those species that either live near the glaciers or on them.

Melting glaciers may affect ocean currents. It was found that freshwater entering the ocean from melting ice sheets can weaken the climate controlling part of the large scale ocean circulation with frantic climate change as a consequence

Which of the following statements about meiosis is correct? Which of the following statements about meiosis is correct? Meiosis
Lapatulllka [165]

Answer:

The correct answer is "Meiosis produces cells that differ genetically from the parent cell".

Explanation:

In contrast with mitosis, which is the cellular differentiation that produces somatic cells; meiosis produces cells that differ genetically from the parent cell. Meiosis is a special type of cellular differentiation that reduces the genetic material by half, and results in the creation of four haploid cells that are genetically distinct from the parent cell. Meiosis allows for the maturation of sexually reproducing cells, and the genetic variations of these cells is one factor that allows for genetic variations among sexually reproducing species, such as humans.

Match the prokaryotic cell structures to the characteristic of life.
djverab [1.8K]

Answer:

1. Nucleoid: Prokaryotes do not have well defined nucleus. Instead, naked DNA or genetic material is found in the these cells which keeps floating freely in the region of cytoplasm called as mucleoid (nucleus-like). DNA carries the genetic information required for growth, development, metabolic activities and reproduction.

Hence, it must match with b. reproduction: DNA ensures that future generations will be similar to parents

2. Cell wall: Cell wall is the outermost layer surrounding the plasma membrane. It is composed of polysaccharides and is found in bacteria, fungi, and plant cells. In bacteria, it is generally composed of peptidoglycans. Antibiotic such as penicillin acts on the cell wall and creates pores in it which kills the bacteria.

Hence, it can be correctly matched with d. homeostasis: taking an antibiotic, such as penicillin, creates holes in the cell wall of some bacteria, so they lose water and die

3. Flagellum: It is a thread or hair like structure which serves the purpose of locomotion in the cells specially in bacteria, protozoa, spermatozoa etc. In bacteria, it helps in moving in the direction of food and moving away from inhospitable environment.

Hence, it can be correctly matched with e. responding to stimuli: move away from a less hospitable environment or towards a more hospitable environment.

4. Pilus: It is a hair like but rigid structure that protrude from the cell surface of the bacteria. It helps in the process of conjugation by forming a conncetion between cell surface of two bacteria.

Hence, it can be correctly matched with a. reproduction: exchanging genetic material in process of conjugation

5. Ribosomes: Ribosomes serve as the site of protein synthesis in the cell. Bacterial ribosomes are composed of two sub-units with sedimentary constant of 50S and 30S.

Hence, it can be correctly matched with c. maintaining homeostasis: protein is needed for enzymes and repairing structures

6. Cytoplasm: It is gel like material found within the cell (excluding nucleus in case of eukaryotes). All the metabolic activities of the cell generally take place in the cytoplasm of the cell.

Hence, it can be correctly matched with f. homeostasis: using energy, all chemical reactions are performed in the cytoplasm

1) How is DNA compacted to form a chromosome?
denis-greek [22]

Answer: Answer is below in the explanation.

Explanation:

As shown in the animation from my school, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes.
