Answer:
Protozoa is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Anton van Leeuwenhoek was the first person to see protozoa, using microscopes he constructed with simple lenses. Between 1674 and 1716, he described, in addition to free-living protozoa, several parasitic species from animals, and Giardia lamblia from his own stools.

Random mutations can occur in an organism's DNA, causing traits that are different from other organisms in that species. Sometimes these mutations can cause problems for the organism, but other times they are beneficial. What is a possible benefit to a random mutation in an organism?
Answer: It can increase an organism’s chances of surviving
Explanation:
compounds formed from the attraction of oppisitely charged ions are called ________.
A. covalent compounds
B. ionic compounds
C. mineral compounds
D. molecular compounds
Answer:
B. ionic compounds
Explanation:
how do mutations affect our communications?
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.
You have been looking at meiosis beginning with a diploid cell that has the genotype AaSs. The alleles in the haploid gametes produced by meiosis are
Answer:
AS, As, aS, as
Explanation:
Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).
According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
AS, As, aS, and as
List the following structures from largest to smallest: proton pump, nuclear pore, cyt c ribosome,
nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

The majority of pesticides do not have a residual effect (i.e., not persistent; lose chemical activity) in the soil.
a) True
b) False
Answer:
B- False
Explanation:
Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Soil can be degraded and the community of organisms living in the soil can be damaged by the misuse or over use of pesticides. Some pesticides are more toxic to soil organisms than others.

Describe how a rainforest can reach a point when it cannot be restored by secondary ecological succession
Answer:Although the secondary forest will be low in diversity and poorly developed, the forest cover will be adequate for some species to return (assuming they still exist). The solution must be based on what is feasible, not overly idealistic, and depends on developing a new conservation policy built on the principle of sustainable use and development of rainforests. Beyond the responsible development of rainforests, efforts to rehabilitate and restore degraded forest lands along with the establishment of protected areas are key to securing rainforests for the long-term benefits they can provide mankind.
Explanation:
i lloke dit up online because i have not did this yet
A very high damaged leads to no restoration of rainforest by secondary ecological succession.
A rainforest can reach a point when it cannot be restored by secondary ecological succession when the large portion of the rainforest is destroyed and most of diversity is vanished. At this time, restoration is impossible due to very high damages.
Ecological resilience is the ability of an ecosystem to be restored through secondary ecological succession after a severe disturbance. Rainforest have a high biodiversity that helps it to resist damage but at a certain limit so we can conclude that very high damaged leads to no restoration of rainforest by secondary ecological succession.

Answer:a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
Explanation:
The American Beaver (Castor canadensis) is one example of a keystone species in North America. In any arrangement or community, the “keystone” is considered one of the most vital parts. In a marine ecosystem, or any type of ecosystem, a keystone species is an organism that helps hold the system together.

They increase the number of available reactant particles
They absorb energy from the products
They provide energy to the reactants
Answer:
They lower the activation energy of the reaction
Explanation:
Enzymes are proteinous biochemical molecules that serve as catalyst in living systems. They speed up the rate of biochemical reactions by lowering the activation energy of the reaction they are involved in.
As this question describes, enzymes possess an active site, which the substrate binds to yield products. The enzymes make the reaction faster by reducing the activation energy of the reaction, which is the energy needed to start a reaction.
When a patient comes to a hospital with severe dehydration, doctors will give
them an IV filled with a salt-water solution called saline, which is isotonic with
the body's blood cells.
Why is the patient not given pure water?
Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.
