What structures have parasite worms lost? What structures/organs are expanded?
Explanation:
Something that is lacking, is a circulatory system. Instead of a typical circulatory system flatworms exchange oxygen with the air outside through diffusion. This is the process by which gases will pass through a membrane from an area of high concentration to an area of low concentration.
The process of meiosis is essential in the sexual reproduction and life cycle of many organisms. The outcome of meiosis is haploid gametes. Which statements correctly describe the importance of meiosis to the life cycle or these organisms?
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
B) Taking a diploid cell to its haploid state occurs during the first cell division of meiosis.
C) Checkpoints during meiosis ensures that chromosome separation occurs accurately, avoiding non-disjunction.
D) DNA synthesis occurs before each cell division in meiosis ensures that the integrity of the chromosomes is maintained.
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.
Answer:
E) Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization.
A) Increasing genetic diversity ensures that no two haploid gametes are exactly the same.
Explanation:
Meiosis is a kind of cell division that strictly occurs in sexually-reproducing organisms. It is the process whereby four daughter cells that are genetically different from their parents are produced. In meiosis, the chromosome number of each daughter cell (gamete) is reduced by half. As highlighted in this question, the meiotic process is essential in the sexual reproduction and life cycle of many organisms.
This importance is attributed to the fact that:
- Reducing the number of chromosomes by half during meiosis ensures the chromosome number is maintained during fertilization. That is, a diploid organism (2n) produces a haploid gamete (n), which becomes diploid again when fertilized by another gamete.
- Increasing genetic diversity ensures that no two haploid gametes are exactly the same. This occurs because of a process called CROSSING OVER, which enables that the alleles of each gamete is recombined to be different from one another in order to promote genetic diversity.

C. Whether the virus has a protein capsid
D. Whether the virus is helical, icosahedral, enveloped, or complex
Answer:
A is the answer i had same answer
The information is necessary to understand how a virus produces the proteins it requires is " whether the virus is in the lytic or lysogenic cycle".
What is virus ?A virus would be an infectious submicroscopic creature that only reproduces inside of live cells. All living things, including plants, animals, even microbes like bacteria or archaea, are susceptible to virus infection.
What is lysogenic cycle?The bacteriophage nucleic acid is integrated into the genome of the bacterial host during lysogeny or a spherical replicon forms in the bacterial cytoplasm.
Therefore, the information is necessary to understand how a virus produces the proteins it requires is " Whether the virus is in the lytic or lysogenic cycle".

Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..

An inflated basketball hold 6 liters of air at 3 ATM. How much air at 1 ATM went into the ball
Answer:
18 litres
Explanation:
Using Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (litres)
V2 = final volume (litres)
According to the information in this question, An inflated basketball hold 6 liters (V1) of air at 3 atm (P1). The volume of air (V2) at 1 atm (P2) that went into the ball can be calculated thus:
Using P1V1 = P2V2
3 × 6 = 1 × V2
18 = V2
V2 = 18 litres.

S. Give three reasons to explain why transpiration occurs mainly through leaves
6. Explain how sunken stomata lower the rate of transpiration
11
with
ftri
Answer:
Due to stomata.
Explanation:
Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature. Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.
Which adaptation allows reptiles to live entirely on land check all that apply
Reptiles' capacity to deposit amniotic eggs is the main trait that enables them to live exclusively on land. Amniotic eggs have a protective shell around them and include specific membranes that give the growing embryo a self-contained aquatic environment. Amniotic reproduction is the name given to this adaptation.
The amniotic egg has a number of crucial characteristics that let it thrive on land. These qualities consist of:
Shell: By minimizing water loss, the embryo's shell protects it physically and keeps it from desiccating (drying out).
Amnion: The amnion is a membrane that covers the embryo and holds amniotic fluid, which acts as a cushion and source of buoyancy.
The chorion is an additional membrane that encircles the amnion. By facilitating gas exchange, it allows carbon dioxide to leave and oxygen to enter the egg.
The allantois is a sac-like organ that aids in breathing and stores metabolic waste products from the developing embryo.
Egg yolk sac: The yolk sac is a source of proteins, lipids, and minerals that feed the growing embryo.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

A. Provide the cell with shape and rigidity
B. Prevent the cell from lysing
C. Protect the cell
D. Provide the cell with locomotion
Answer:
D
Explanation:
I believe locomotion would be the job of the flagellum
The correct option that is not a function of the bacterial cell wall is : ( D ) Provide the cell with locomotion
The Bacterial cell wall acts mainly as a protective cover to the cell of the bacterium, protecting the cell from lysing ( preventing the breakdown of the cell via osmotic pressure ). The cell wall also provides the cell with shape a and rigidity.
While The locomotion of the cell is not the responsibility of the cell wall but it is made possible by the flagellum.
Hence the non - function of a bacterial cell wall is providing the cell with locomotion.
