How does your body respond to a decrease in blood glucose
Svetradugi [14.3K]

Answer:

When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal.

Explanation:

Which is true regarding the process of meiosis I?
sashaice [31]

Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)

Explanation:

In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.

Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.

A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:

--> the chromosomes replicate once and

--> the nucleus and cell duplicate ( divide equally) twice.

As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

You have studied some microbes that cause disease. Understanding how microbes grow and multiply is important when identifying an
Mila [183]

Answer:

Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm

Function: metabolic functions are carried out in the bacterial cytoplasm

Replication: generally asexual (binary fission)

Explanation:

Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles . Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, <em>Salmonella</em> is a genus of infectious bacteria that may cause an outbreak. <em>Salmonella</em> infection may be prevented by eliminating conditions where they can multiply. Measures to prevent <em>Salmonella</em> outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.
