Answer:
Sperm have a well-protected head and a motor to help them travel.
Explanation:
Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.
- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.

Platyhelminthes, Nematoda, and Annelida
Explanation:
Cnidarians are like jellyfish and sea urchins, Porifera are sponges and Placozoa are barely even animals. They look more amoeba than anything. While those three groups are wormlike in appearance or true worms.

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

What happens to genetic material during cell division?
Answer:
The genetic material in cells is called DNA (deoxyribonucleic acid). Before cell divion, DNA is duplicated, or copied. ... Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).

Why do you think the strand of DNA
coming in from the left side of the screen
is becoming two thinner strands?
Answer:
they might be spliting(reproduction) to make offspring
Explanation:
DNA replication
What does it mean when DNA splits?
Two strands of DNA come together to form a twisted, ladder-like structure. Hydrogen bonds between the bases of each strand create the double-stranded structure. The cell must split the two strands to allow the replication machinery to access each strand and copy it.
What causes the DNA to split apart during replication?
In order to unwind DNA, these interactions between base pairs must be broken. This is performed by an enzyme known as DNA helicase. DNA helicase disrupts the hydrogen bonding between base pairs to separate the strands into a Y shape known as the replication fork.

Some plants have the ability to make the stamens mature first before the pistils to prevent itself from self-pollinating. ... If a situation as such would happen, there will be no pollen left in that flower to land on the stigma to start the fertilization of the plant.

Which of the following correctly shows how energy flows in an ecosystem? *
producer - sun - decomposer – consumer
sun - producer - consumer – decomposer
decomposer - producer - consumer – sun
consumer- decomposer - sun – producer
Answer:
The correct answer is - sun - producer - the consumer – decomposer.
Explanation:
Sun is the ultimate source of the energy on the earth and is responsible for all the energy that is present or moves between various organisms in an ecosystem.
Sun provides energy in the form of light energy which is converted by the producers by photosynthesis into food and when consumers eat producers for food and energy 10 percent of energy passes from the producers to the consumers and the rest 90% lost during life processes. At the end of the chain, decomposers get energy from the dead matter of the consumers.

Bacteriophages that induce bacterial cell lysis are called
Answer:
Bacteriophages that induce bacterial cell lysis are called virulent phages.
Explanation:
Bacteriophages correspond to viruses with an affinity for prokaryotic cells to be used as hosts for replication. They act both by invading the bacterial cell and by introducing their genetic material into it.
Some bacteriophages are capable of lysing or destroying the host bacterial cell after replication of their genetic material, receiving the name of virulent phages.
Bacteriophages that induce bacterial cell lysis are known as VIRULENT phages.
A bacteriophage is any virus capable of infecting and replicating within a prokaryotic cell (i.e., bacteria and archaea).Bacteriophages can be classified as lytic bacteriophages, which replicate through the lytic life cycle, and temperate bacteriophages, which replicate using both lysogenic and lytic cycles.For example, the phage lambda of Escherichia coli is an example of a temperate bacteriophage.In conclusion, bacteriophages that induce bacterial cell lysis are known as VIRULENT phages.
