Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit
Answers
Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.

A. Releases a hormone if blood calcium levels get too high
B. Releases hormones to regulate the endocrine system
C. Regulates the pituitary gland
D. Releases insulin if blood sugar levels get too high
Answers
A
The thyroid gland secretes the thyroid hormones that releases a hormone if blood calcium levels get too high and in this way regulats the calcium level in the blood that is present in option A.
The thyroid gland plays a crucial role in regulating metabolism, which is the process by which the body converts food into energy. Metabolism is a complex process that involves various chemical reactions that take place within the body's cells. The thyroid hormones T4 and T3 are responsible for regulating many aspects of metabolism such as thyroid hormones increase BMR, which means that the body burns more calories even when one is not doing any physical activity.

Which can more efficiently supply nutrients and
expel waste products?
A. larger cells
B. smaller cells
C. cells with lower surface area to volume ratio
D. cells shaped like a cube
Answers
Answer:
Smaller Cells
Explanation:
Basically, small cells have larger surface area but smaller volume, its vice versa for larger cells.
Not to forget that the functions of a cell are related to the diffusion, osmosis and active transport movement.
Factors to consider for a faster diffusion/ osmotic movement includes:
Surface Area
Size of molecule
Difference in concentration gradient
Temperature
Distance
So as per the factors, when there is a larger surface area, the rate diffusion/ osmosis increases hence increasing its efficiency.

What causes the formation of a cervical plug a testorone b progesterone c luteal d estroge e follicle
Answers
Answer:
b progesterone
Explanation:
The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.
The progesterone, encourages the production of thick fluid/ mucus which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.
Answer: The correct option is B (progesterone).
Explanation:
The cervix is the ring of muscles also called the neck of the uterus in female reproductive system. This protrudes through the anterior wall of the vagina, opening into it at the external os.
After the fertilization of the ovum by the spermatozoa, the uterus prepares for the implantation which results from the secretion of hormones. Under the influence of oetrogen, secreted by the developing follicle, the cells of the endometrium divide rapidly causing the endometrium to build up and thicken.
While the viscosity of cervical mucus changes in response to hormone levels and during pregnancy, progesterone fosters the production of highly viscous mucus resulting in the formation of a plug that forms a physical barrier to bacteria and prevents their ascension into the uterine cavity. This plug is called CERVICAL PLUG.

Microbeads are tiny, smooth, plastic spheres found in common household products such as facial soap. These beads, measuring from 0.0004 to 1.24 mm, roughly the size of some fish eggs, are too small to be removed by water treatment systems. Thus, they end up in rivers, lakes, and other bodies of water. The accumulation of these microbeads is an environmental concern for aquatic biologists because microbeads
(1) make the lakes and rivers cloudy and dirty, affecting their appearance
(2) may stick to some household water pipes, preventing drainage problems
(3) could be mistaken for food by some species, working their way up the food chain
(4) could clog fishing nets, affecting the ability of fishermen to catch fish
Answers
Answer:
(3) could be mistaken for food by some species, working their way up the food chain
Explanation:
Microbeads, such as other microplastics, can affect wildlife in many ways, but mostly by
IngestionIntroduction and transference in the trophic webInteraction with other contaminantsMicroinvertebrates, bacteria, and viruses colonize these microplastics and can be transported long distances.Organisms like mollusks, crustaceans, fishes, birds, turtles, among many others, might confuse these elements with food and eat them. Microbeads might float or accumulate in sediments and be ingested by different benthonic species. The ingestion of microbeads by inferior links in the trophic web means a direct entrance in the trophic web where many superior links are affected too while feeding with already contaminated prey.
The ingestion of microbeads can cause a significant impact on the growth, development, and reproduction of freshwater and seawater species.
Microbeads, like other microplastics, characterize for their durability in time and resistance, which means that the ones that are already in the oceans and rivers will last there for centuries.
