Answer:

Cnidaria

Organisms have specialized stinging cells

→ Two type of body plans exist - polyp and medusa

Porifera

→ Organisms lack symmetry

→ Adult forms are sessile

→ Organisms obtain food by filtering water

→ Phenomenon of alternation of generation is observed.

Explanation:

Cnidaria, also known as the coelenterata, is a phylum of mostly marine animals having about 9,000 living species. Some of them include the corals, hydras, jellyfish, sea anemones, sea whips, etc. They possess specialized cells known as cnidocytes ( also known as “stinging cells”).  These cells can seen around the mouth and tentacles cnidarian. They immobilize their prey with toxins. These Cnidaria have two body plans and which are polyp and medusa.

The phylum Porifera are known as the pore bearers. It has about 5000 species. Their adult forms are sessile. They live permanently attached to rocks. They can under alternation of generation. They possess no organs in their bodies. Also, they lack symmetry. They can be referred t as filter feeders because they obtain food by filtering water.

if the codon for phe is 5'- u u c 3' what is the anticodon that would be found on the trna that carries phe?

Answers

if the codon for phe is 5'- u u c 3' , AAG is the anticodon that would be found on the trna that carries phe. Their function is to base pair with the codon on a strand of mRNA during translation.

An amino acid's specific genetic information is encoded by a codon, which is a DNA or RNA sequence made up of three nucleotides (also known as a trinucleotide). A trinucleotide sequence called an anticodon is found at one end of a transfer RNA (tRNA) molecule and is complementary to a corresponding codon in an mRNA sequence. During protein synthesis, each time an amino acid is added to a developing polypeptide, a tRNA anticodon couples with the corresponding codon on the mRNA molecule to ensure that the correct amino acid is incorporated into the polypeptide.

Which organism would probably survive in a hot tub?
a. E coli
b. Vibrio cholera
c. Entamoeba histolytica
d. Pseudomonas aeruginosa

Answers

Pseudomonas aeruginosa organism would probably survive in a hot tub. So the correct option is D.

The organism most likely to survive in a hot tub is Pseudomonas aeruginosa. This is because Pseudomonas aeruginosa is a common waterborne bacterium that can survive in a wide range of environments, including warm water. It is also resistant to many disinfectants, making it difficult to eliminate from water sources.

On the other hand, E. coli is a bacterium that is commonly found in the intestines of warm-blooded animals and humans and may indicate fecal contamination in water. Vibrio cholera and Entamoeba histolytica are both waterborne pathogens that can cause severe gastrointestinal illness in humans and are unlikely to survive in hot tub temperatures.

if you had a 10% salt solution on one side of a beaker and a 5% solution on the other side and they were sperated by a semipermeable membrane which way would the water move? why?

Answers

If you had a 10% salt solution on one side of a beaker and a 5% solution on the other side separated by a semipermeable membrane, the water would move from the 5% solution side to the 10% solution side.

This is because water will always move from an area of low concentration (5%) to an area of high concentration (10%) in an attempt to equalize the concentration levels on both sides of the membrane.

Since the membrane is semipermeable, it allows the passage of water molecules but not salt ions, so the water will move to dilute the higher concentration of salt on the 10% solution side.

voltage-gated channels are characteristically found in the plasma membrane of which of the following group of answer choices
A. motor-endplate of the myofibers
B. dendrite
C. neuronal cell body
D. transverse tubule

Answers

Voltage-gated channels are characteristically found in the plasma membrane of the transverse tubule. The answer is D.

Transverse tubules are invaginations of the plasma membrane that run perpendicular to the myofibrils. They are important for the propagation of action potentials from the surface of the muscle fiber to the interior of the cell.

Voltage-gated channels are proteins that open and close in response to changes in the membrane potential. When they are open, they allow ions to flow through the membrane, which can change the membrane potential.

This change in membrane potential can then trigger the opening of other voltage-gated channels, and so on. This process is called action potential propagation.

Action potential propagation is essential for muscle contraction. When an action potential reaches the transverse tubule, it triggers the release of calcium ions from the sarcoplasmic reticulum.

Calcium ions bind to troponin, which causes tropomyosin to move out of the way, exposing the myosin-binding sites on actin. Myosin heads can then bind to actin and use ATP to power the sliding of the filaments past each other, which causes muscle contraction.

Therefore, voltage-gated channels are essential for muscle contraction. They are found in the plasma membrane of the transverse tubule, and they are responsible for the propagation of action potentials from the surface of the muscle fiber to the interior of the cell.

Therefore, the correct option is D, transverse tubule.

What is Biome?

Biomes are major ecological areas that are based on the general temperature and climate of the area, including the physical aspects such as the topography of the landscape, the water and soil present, and the type of vegetation. Biomes range from tropical rainforests to arctic tundra, and each biome has a unique set of environmental factors that contribute to the flora and fauna found within that region.

Why Tundra is least altered by human activity world-wide?

Tundra is the one that has been least altered by human activity worldwide because of the following reasons:

Tundra is an ecosystem that is characterized by extremely low temperatures, low precipitation, and short growing seasons. The soil is typically frozen year-round, which makes it difficult for plants to take root, and the harsh climate limits the number of animals that can survive in this environment. Human activity in tundra biome is limited, due to the above-mentioned factors and these regions are typically isolated from human settlements or infrastructure.

Quartz particles of varying sizes are dropped at the same time into deep, calm water. which crow section best represents the settling pattern of these particles?

Answers

The settling pattern of quartz particles of varying sizes that are dropped at the same time into deep, calm water can be represented by the d. crow section. This section of the sedimentary column represents sorted sediments that are deposited based on their grain size.

When quartz particles of varying sizes are dropped into water, they will settle at different rates due to their differences in size. The larger particles will settle faster and the smaller particles will settle slower. Over time, the larger particles will form a layer at the bottom of the water, followed by a layer of slightly smaller particles, and so on. This is known as sorting.The crow section represents the result of this sorting process. It shows the different layers of sediment that have been deposited based on their grain size, with the largest grains at the bottom and the smallest grains at the top. The crow section is commonly used in sedimentary geology to help interpret the depositional environment of a rock sequence.

In summary, the settling pattern of quartz particles of varying sizes that are dropped at the same time into deep, calm water can be represented by the d. crow section, which shows sorted sediments deposited based on their grain size.

consider the blood typing results illustrated here. the solid coloring indicates that no agglutination occurred during the test. the blotchy coloring indicates agglutination occurred. what is the blood type of this individual?

Answers

Based on the blood typing results illustrated, we can determine the blood type of this individual by observing the presence or absence of agglutination. Agglutination refers to the clumping together of red blood cells in response to specific antibodies. To determine the blood type, we need to consider two main factors the presence or absence of A and B antigens on the red blood cells, and the presence or absence of anti-A and anti-B antibodies in the plasma. In the given results, the solid coloring indicates no agglutination, which means there was no reaction between the red blood cells and the corresponding antibodies.

The blotchy coloring, on the other hand, indicates agglutination, suggesting a reaction occurred. Let's analyze the given results to determine the blood type:

- If the red blood cells show agglutination with the anti-A antibody and no agglutination with the anti-B antibody, the blood type is A. - If the red blood cells show agglutination with the anti-B antibody and no agglutination with the anti-A antibody, the blood type is B.

- If the red blood cells show agglutination with both anti-A and anti-B antibodies, the blood type is AB. - If there is no agglutination with both anti-A and anti-B antibodies, the blood type is O. Based on the given results, we can see that there is agglutination with the anti-A antibody and no agglutination with the anti-B antibody. Therefore, the blood type of this individual is A.

About Blood typing

Blood typing is the science of classifying blood from a group based on the presence or absence of inherited antigenic substances on the surface of the red blood cell membrane. This is due to differences in the types of carbohydrates and proteins on the surface of the red blood cell membrane. Some say that blood type O is the universal donor blood group and AB is the universal recipient blood type. That is, blood type O is considered to be donated to all types of blood groups in the ABO classification system (A, B, O, and AB). A, B, AB, and O are the most commonly known blood groups. Among the four blood types, those with blood type O are said to be the least likely to get sick. Although they rarely get sick, people with blood type O can get sick quickly.

gregor mendel’s experiments overturned the idea of blending inheritance.

Answers

Gregor Mendel’s experiments overturned the idea of blending inheritance. This statement is true.

Mendel conducted his experiments on pea plants, where he observed the transmission of different traits from one generation to the next. He chose pea plants because they had easily visible traits and were able to self-fertilize. Mendel discovered that each individual pea plant has two copies of each gene - one from each parent.

These two copies are called alleles, and they can be either dominant or recessive. When the dominant allele is present, it will determine the physical characteristics of the plant. However, when the recessive allele is present, it will not be expressed in the physical appearance of the plant. Mendel was able to cross-breed pea plants with different characteristics to produce a new generation of plants with specific traits.

He discovered that the traits were inherited independently of each other. This means that each trait is inherited independently and is not blended with other traits from the parents. This was a significant finding because it challenged the prevailing theory of blending inheritance.
