Describe the two general body forms of cnidarians, which include jellyfish and corals
Answers
A Cnidarian can have one of two basic body types, polypoid or medusoid. The polypoid is the configuration of corals and anemones, with the tentacles and mouth generally facing up, and the other side affixed to a substrate or connected to a colony of other creatures of the same species.
hope this helps
Cnidarians, such as jellyfish and corals, have two body forms: polyp and medusa. Polyps are typically immobile with an upward-facing mouth and tentacles, while medusa are able to move with a bell-like body and downward-facing mouth and tentacles. Some cnidarians can display both body forms in their life cycle.
Explanation:Cnidarians, including jellyfish and corals, exhibit two general body forms known as polyp and medusa. The polyp form, akin to a stalk, is sessile (immobile) with tentacles and a single opening facing upwards. Examples include freshwater species of the genus Hydra and sea anemones. The medusa form is motile (able to move) and bell-shaped, with the mouth and tentacles hanging down from the body. Jellyfish are perhaps the most known representatives of the medusa form.
Additionally, some cnidarians are dimorphic, exhibiting both body forms during their life cycle. In these species, the polyp often serves as the asexual phase, with the medusa functioning as the sexual stage that produces gametes. However, species belonging to the class Anthozoa, which include sea anemones, sea pens, and corals, only exhibit the sessile polyp body form throughout their life cycle.

When does the cell pinch off and divide into two daughter cells in mitosis?
A. Telophase
B. Interphase
C. Cytokinesis
D. Anaphase
Answers
Answer:
C. Cytokinesis
Explanation:
During the cell cycle, the division of cytoplasm (cytokinesis) is followed by the division of the nucleus (karyokinesis). Cytokinesis is occurred differently in plant cells and in animal cells during cell division. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells are formed whereas, in plant cells, cytokinesis takes place by a cell plate formation
In mitosis during cytokinesis phase the cell pinches off and divide into two daughter cells .The correct option is C.
In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division.
In general, mitosis is preceded by S phase of interphase and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle. In cytokinesis,the cell pinches off and divide into two daughter cells in mitosis.
Thus, the cell pinch off and divide into two daughter cells in mitosis during cytokinesis. The correct option is C.

A student used a microscope to get a very detailed look at pollen grains from an apple tree. In order to do this, the student first had to prepare the pollen grains to withstand the vacuum conditions and high energy beam of the microscope. The image below shows the student's view of the pollen grains through the microscope.
Answers
An electron microscope was used to visualize apple tree pollen grains, produced detailed micrographs. The pollen grains have two cells and two coverings, and their motion in water demonstrates the existence of atoms. Microscopes are an essential tool for studying such minute particles.
Explanation:To understand the detailed view of pollen grains from an apple tree as seen under a microscope, it's key to know that microscopes, such as the electron microscope used here, enable scientists to scrutinize small objects at a high scale and resolution. Images captured with a microscope are often referred to as micrographs.
In the micrograph of the pollen grains, the grains are about 50μm long and appear bean-shaped. 'Electron wavelengths' or the wavelengths emitted from the microscope are 100,000 times shorter than visible-light photons, allowing for a much higher resolving power to see finer details, such as the ones shown in the SEM micrograph of the pollen.
The mature pollen grain, developed from microspore mother cells, comprises two cells, the pollen tube cell, and the generative cell which resides inside the tube cell. It also has two layers, the inner layer (intine) and the outer layer (exine). The behavior of a pollen grain in water under a microscope yields a phenomenon known as Brownian motion, which illustrates the atom's existence due to the fluctuations in the number of atoms and molecules colliding with a mass that results in its complex paths of movement.

The term 'parents' refers to individuals who are responsible for the care and upbringing of their children. This term can also extend to grandparents or extended family members in cases where they take up the role of the primary caregiver. In genetics, 'parents' also refer to organisms contributing genetic material to offspring.
Explanation:The term 'parents' is commonly used in a social or familial context to refer to individuals who have offspring either biologically, through adoption, or through other familial relationships. They are responsible for the upbringing and care of their children.
'Parents' in a wider context can also include 'parents of parents', often referred to as grandparents who, in many cultures, play a crucial role in a child's upbringing. In certain circumstances, these grandparents may take on the role of primary caregivers, effectively becoming parents themselves.
Beyond direct parenting, there are several forms of family structures, including single-parent families, blended families (where there are step-parents and/or step-siblings), and extended families, where others like aunts, uncles, cousins also play significant roles in a child's upbringing.
Additionally, in genetic terms, the term 'parents' is used to describe individual organisms that contribute genetic material to create offspring. This biological concept of parents exists parallel to, and distinct from, social and legal aspects of parenthood.

the distance of the star from Earth using parallax method
Answers
the answer for this question is the distance of the star from sun using parallax method
Answer:
The correct answer will be option the distance of the star from Sun using parallax method.
Explanation:
Parallax method or trigonometric parallax is a method of measuring the distance of nearby stars in space on the basis of displacement of stars against the background.
Since a student observes the position of the star in summer and then after 6 months in winter, star changes its position or displaces which can be measured by the student along with measuring parallax angle and drawing a baseline from the Sun as Earth revolves in orbit around the Sun. So by using the parallax method and the formula he can easily determine the distance from the Sun.
Thus, the distance of the star from Sun using the parallax method is the correct answer.

here is the youngest crust on Earth most likely located?
A. At divergent boundaries in the middle of the ocean
B. At transform boundaries where two plates slide past each other
C. At convergent boundaries where two continents meet
D. At convergent boundaries where oceans and continents meet
Answers
Answer:
Option (A)
Explanation:
In a divergent plate motion, two plates move in the opposite direction. Due to this plate motion, the magma rises up and comes out to the ocean floor, forming a long ridge which is commonly known as the mid-oceanic ridge. As soon as this magma comes out to the surface, it solidifies and forms igneous (basaltic) rocks.
These rocks are of geologically the youngest because they are directly forming from the cooling and solidification of magma. The rocks that are present at or near the mid-oceanic ridge are younger than the rocks that are away from the mid-oceanic ridge.
Thus, the youngest rocks are formed along the mid-oceanic ridge at a divergent plate boundary which is at the middle of the ocean.
Thus, the correct answer is option (A).
The youngest crust on Earth probably lies at divergent boundaries in the middle of the ocean. Therefore, the correct option is A.
The youngest crust on Earth is most likely to be found at isolated boundaries in the center of the ocean. Divergent boundaries are places where tectonic plates move apart and leave a gap. Magma in the mantle rises to fill the void, solidifies and forms fresh oceanic crust. The youngest crust on Earth is continually being built up by a process known as sea floor spreading. The ongoing regeneration and spreading of Earth's sea floor is facilitated by the continuous build-up of fresh oceanic crust at distinct boundaries.
Therefore, the correct option is A.

Algae can reproduce by _____. fission sexual reproduction fragmentation all of the above
Answers
Answer:
fragmentation
Explanation:
Algae can reproduce by fragmentation. Most algae that are small reproduce asexually using fragmentation or by cell division. Larger algae on the other hand reproduce by use of spores. Fragmentation is a mode of asexual reproduction in which the parent divides into two or more fragments which later develops into a new organism.A good example of an algae that uses fragmentation is green algae also called Spirogyra. The parent divides into distinct pieces which can then produce an offspring.The correct answer is All of the above
Explanation:
Algae include multiple organisms that are mainly classified as eukaryotic and rely on photosynthesis like plants, although they are quite different from plants. In terms of reproduction, algae can reproduce in many ways depending on the sécies, this includes asexual reproduction that occurs through fission in which cells divide into two or more cells to reproduce; fragmentation in which the algae breaks into different fragments and each of these is able to form a new complete individual and also, algae can reproduce through sexual reproduction which means there are female and male gametes involved. According to this, it can be concluded algae can reproduce by all of the above (fission, sexual reproduction, and fragmentation).

What type of bond holds two different strands of DNA together?
Answers
Answer:The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
Explanation:
Final answer:
Hydrogen bonds hold the two strands of DNA together by connecting the nitrogenous bases. This bond is weaker than the covalent bonds in the DNA's structure, enabling DNA replication.
Explanation:
The type of bond that holds two different strands of DNA together is the hydrogen bond. These bonds occur between the nitrogenous bases in a way that adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G), forming base pairs. The DNA molecule appears like a ladder twisted into a double helix, with the base pairs acting like the rungs and the sugar-phosphate backbone forming the sides of the ladder. The hydrogen bonds are weaker than the covalent bonds in the sugar-phosphate backbone, which allows the DNA to unzip easily for replication while ensuring stability of the helical structure.

If the DNA sequence reads TAT, what is the mRNA codon?
Answers
Answer:
AUA
Explanation:
Thiamine pairs with Adenine. However, in mRNA, the Thiamine base does not exist. It is replaced by Uracil. Therefore, instead of the A in the DNA strand pairing with a T, it pairs with a U on the mRNA.
The DNA sequence that reads TAT gives rise to an mRNA codon that corresponds to the amino acid tyrosine
Explanation:
According to the central dogma of life the DNA gets transcribed to RNA which gets translated to the protein, the protein is the ultimate macromolecules that helps in the metabolic activities of the human, an important aspect of this process is that not all DNA is converted into RNA similarly not all RNA is converted to protein, only the mRNA is converted to the protein based on a degenerative codon mechanism.

Before starting kindergarten, Tina had to receive shots to protect her from an infectious disease called measles. Does Tina now have active or passive immunity against measles?
Answers
Answer:
i think it's passive
Explanation:
Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
Final answer:
Tina has active immunity against measles, which she acquired through vaccination. This has prepared her immune system to fight off future exposure to the measles virus, ensuring she is protected against the disease.
Explanation:
Tina has received active immunity against measles. Active immunity occurs when the immune system is exposed to a pathogen or parts of a pathogen and develops its own antibodies in response. Vaccinations, like the MMR vaccine which stands for measles, mumps, and rubella, introduce a weakened or dead form of the pathogen into the body without causing illness.
This stimulates the body's adaptive immune response to produce antibodies, providing long-lasting protection against these diseases. Tina's body will now have the memory to recognize and effectively fight off the measles virus should she be exposed to it in the future, thanks to the process initiated by the vaccine.
