If a sea urchin eats two sea weed and one sea grass, how many uts Hg does the sea urchin have?

Seeds offer the embryo protection, nourishment, and a mechanism to maintain dormancy for tens or even thousands of years, ensuring that germination can occur when growth conditions are optimal. Seeds therefore allow plants to disperse the next generation through both space and time.

Answer:

C. Seeds protect the plant embryo and its food source

Explanation:

took the test

Answer:

Complementary to each other

Answer:

Complementary nitrogenous bases

Explanation:

The codons and anticodons have complementary nitrogenous bases, allowing them to base pair. Because the kind of amino acid attached to a tRNA depends on the tRNA's anticodon, the base pairing between the anticodons and codons brings a specific sequence of amino acids to the ribosomes. For example, the codon labeled F is complementary to the anticodon UAC and codes for the amino acid methionine.

The the levels of protein structure in the molecule would be tertiary and quaternary structures.

The levels of protein structure are as follows:

The primary structure is the peptide bonds of the amino acids.

The secondary structure is the alpha and beta helices.

Tertiary structure are folds in the protein structure.

Quaternary structure is the association of protein chains.

Therefore, the levels of protein structure in the molecule would be tertiary and quaternary structures.

Answer:

Cookies are ok not the best but ok

Explanation:

1. The milk will be turned into curd in bowl A due to the lactobacillus bacteria and not in other bowls B, C.

Lactobacillus is the bacteria required for the formation of curd and it requires an appropriate temperature for its growth. Lukewarm milk not being very much cool and hot provides that appropriate temperature and hence lukewarm milk get converted into milk.

2. Bowl B and C contains hot and cold milk that do not provide required temperature for the growth of bacteria due to which bacteria does not grow in them and they are not converted into curd.

3. Bowl D placed in refrigerator, so the the bacteria unable to divide because they does not get the required temperature and doesn't changed into curd.

Answer:

Mushrooms are the advanced members of a fungi group belonging to the class Basidiomycetes. They grow on dead and decaying matters like dung, and old rotten logs which are rich in organic matter. Therefore, they are saprophytic fungi.

Bottlenose dolphins use the specialized roles of diver and barrier while participating in cooperative hunting.

This is a hunting technique used by dolphins in which five of its members form a barrier while one dives to catch the prey.

This is a form of cooperative hunting which therefore makes option C the most appropriate choice.

Answer:

As organisms adapt to changing conditions, they evolve in a way to fit their surrounding environment. According to Darwin's survival of the fittest concept, organisms that can adapt to fluctuating conditions are more fitter and hence selected by nature.

Here fitter means reproductive superiority.

Answer:

i am a ice and the next morning the sun was warming and i changed my form as a water and the sun was too hot that i changed my form to gas and went into the sky.

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Answer: i would say for number 2 its A and number 3 D

Explanation:

for number 2 its A and number 3 D.

The work done on q by the electrostatic or Coulomb force is independent of the direction taken because it is a conservative force. The gravitational force in the absence of dissipative forces like friction is exactly identical to this.

When a force is conservative, it is possible to define a potential energy that goes along with the force. Because the potential energy varies solely on position, managing it is typically simpler than calculating the work directly.

Electric potential energy and gravitational potential energy are quite similar. Without having to interact directly with the force, potential energy accounts for the work carried out by a conservative force and provides additional insight into energy and energy change.

Therefore, for number 2 its A and number 3 D.

Oils are lipids which are soluble in organic solvents and insoluble in polar solvents such as water. For saving on heating oil prices is to knock the lowering down temperature a few degrees. The Department of Energy research reports that for every degree cooler we can save between 1-3%.

Polar solvents have large dipole moments because they contain bonds between atoms with different electronegativity, such as hydrogen and oxygen.

Non polar solvents forms bonds between atoms with similar electronegativity, such as hydrogen and carbon.

It is possible to still keep oil heat bill down by looking into weatherproofing home, smartly using an efficient thermostat.

Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. The statement they will both be recorded in joules is  best describes Gabriel’s measurements. Correct Option is 2.

Energy and work are both physical quantities measured in joules (J) in the International System of Units (SI). In this experiment, Gabriel is measuring the energy and work associated with the ball rolling down a hill, and both measurements will be expressed in joules. Energy represents the capacity to do work, and work is the transfer of energy that occurs when a force is applied to move an object over a distance. Both energy and work are directly related and are measured in the same unit, joules, which is a measure of energy or work.
