Describe the reproductive cycle of most scyphozoans
Answers
The reproductive cycle of most scyphozoans is early in the spring, ephyrae transform into young medusae. These develop over the summer, achieve sexual maturity, reproduce sexually, and then perish.
What is a reproductive cycle?The reproductive cycle is the one that shows the reproduction of an organism. Scyphozoa reproduce both sexually (medusa) and asexually (polyp).
While both types exist, the medusa (sexual) form is more common. Sexual reproduction is not an inside process. Males release sperm into the sea, while females release eggs.
Most scyphozoan jellyfishes, including most large jellyfishes, have a two-part life cycle: free-swimming medusa and bottom-dwelling polyp (though there are significant exceptions).
Therefore, most scyphozoans reproduce in the spring, when ephyrae convert into young medusae. These grow over the summer, reach sexual maturity, reproduce sexually, and then die.

TUESDAY, JANUARY 19, 2021 What are the 8 taxons (levels) in order? What are the 6 kingdoms Taxons Kingdoms
Answers
Answer:
-8 taxonomic levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
- 6 kingdoms: Eubacteria, Archaebacteria, Protist, Fungi, Plantae, Animalia.
Explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
The categories where organisms are classified into are:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.- The archaea domain is composed of prokaryotic unicellular microorganisms that lack a nucleus, nuclear membrane, and organelles, but they have a cell wall that protects the cell. These organisms are capable of inhabiting in places with extreme temperature, salinity, acidity, or pH, among others. They reproduce asexually.
- The bacteria domain is composed of a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also present a capsule. They reproduce asexually.
- The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually.
Kingdom: Includes different phyla closely relates. The bacteria domain includes the Eubacteria kingdom. The archaea domain includes the archaebacteria kingdom. Finally, the eukarya domain is divided into four kingdoms: Protist, Fungi, Plantae, and Animalia. Phylum: Includes different classes closely related.Class: Includes different orders closely relates.Order: Includes different families closely relatedFamily: Includes different genera closely relatesGenus: Includes many species.

The number of daylight hours will remain constant at : ( B ) The equator
As the earth continues to revolve around the sun, It brings about the changes in seasons ( winter summer, spring and autumn ). During each season the daylight hours varies slightly across each place. While
The equator receives sufficient sunlight which makes its daylight hours fairly constant as the earth revolves around the sun. also the temperature at the equator is warm all round the seasons.
Hence we can conclude that the number of daylight hours will remain constant at the Equator.

Please and don’t waste my time bu saying that you don’t know the answer. thank you :) I hope you have a nice day
Answers
Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.

(This is 7th grade science)
Answers
Answer:
No
Explanation:
Atoms and molecules are not alive as they do not exhibit all, or any, of the eight characteristics of life. Cell theory also states that a cell is the smallest unit of life, and atoms and molecules are much, much smaller than a cell — in fact, they make up cells.
Therefore, they are not considered living things.

Although molecules and atoms are both apart of something that is living, this doesn't mean a single atom or molecule can live on their own.

During the cell cycle, the cell duplicates its genetic material. Moreover, also during this cycle, the cell synthesizes all materials required for its division.
The cell cycle can be divided into an interphase and a mitotic (M) phase.
The interphase is in turn divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material by a process called DNA replication.
During G1 phase and G2 phase, the cell grows and synthesizes all materials (i.e., proteins) required to enter into the M phase.
