Answer:
e. is mostly asexual, with sexual as a second option.
Explanation:
Protist are unicelluar eukaryotic microorganims. Example include:
<u><em>Amoeba</em></u> <u><em>proteus</em></u>
<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>
Dinoflagellates, etc.
Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.
Protist reproduce asexual by binary fission or by budding.
Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.
Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.
They also reproduce sexually by conjugation.
Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.
The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.
<u>Asexual Reproduction:</u>
This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.
- The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
- Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
- Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.
<u>Sexual Reproduction:</u>
- A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
- That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
- These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.
Answer: False
Explanation:
The urethra is a tube which runs from the bladder to the end of the penis. It functions by carrying the urine and semen outside the male body.
Urethra is made of two components. Prostatic urethera is the part that runs from the bladder through the prostrate.
The penis is only organ which carries both the fluids out of the body.
Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is <em>Maximal Velocity</em> (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.
<span>The common difference between the three organisms
is the area in which they specifically live or stay in the ocean. Planktons can’t
be seen by the naked eye and they require microscopes to be detected. Planktons
usually float in the water and they cannot move on their own that’s why they
are dependent in the movement of the water.
Nektons are organisms that swim through the water and they live in different
depths in the ocean ecosystem. Nektons are composed of fish and other mammals
that propel themselves through the water.
Benthos are organisms that live in the ocean floor and many of these organisms
stay in one place by attaching themselves to rocks. This adaptation protects
them from crashing waves and drastic water movements. Other benthos are known
to burrow in the ocean floor either for food or protection.</span>
