Since they have a greater metabolism, smaller creatures breathe more quickly.

What is Oxygen consumption of an Experiment?

1. In general, the rate of oxygen consumption increases with the increase of temperature. So, here at 30 degree the rate of consumption will be the highest, then at 15 degree, at zero degree it will be ice droplets.

2. The aerobic bacteria present in the water respire in the presence of oxygen. at 0,15 and 30 degree. Here anerobic bacteria can be taken as a control.

So, a culture with medium of aerobic bacteria/yeast can be taken.

It is kept in shaking condition 150-200 rpm and then the temperature is kept at 37 degree.

Bacteria has a doubling time of twenty mins, and yeast has a doubling time of 90mins. So, it is kept at overnight incubation for proper growth of the bacteria. Water droplets are visible at the cap.

At 30 degree the consumption is maximum, then the 15 degree is relatively lower and higher is no consumption at 0 degree where it is frozen.

The oxygen consumption is related to the respiration rate of aerobic bacteria , yeast.

In human beings, curly hair is incompletely dominant over straight hair, such that heterozygous individuals have wavy hair. In the following crosses, in which the phenotypes of the parents are given, what are the gametes produced by each parent, and what will be the hair textures of the potential offspring? Use Punnett squares as part of your answers.

Answers

Answer:

A genetic cross involves two parents for a specific trait, such as the hair trait. The gene has variations called alleles. In one gene, one allele is dominant over the other. The complete dominant allele can be found in both purebred and heterozygous forms and suppresses the recessive character. Here, the curly hair is incomplete dominant over the straight. Wavy hair is produced in heterozygous states; this is an example of incomplete dominance.

When both HH' parents are crossed, then each parent will form the H and H' gametes. Out of the three offspring, one curly, two wavy, and one straight will be formed. The punnet square is explained below in the image.

Hence, when two people with wavy hair are crossed, three types of offspring are formed, such as those with curly, wavy, and straight hair. The genotype and phenotype ratio is 1:2:1.

Answers

Because water (Hydrous minerals & water ice) and other organic molecules/substances had been found on mars and some other moons. These are the building environments for life. For example on earth, unicellular organisms and other like archaea can survive in very extreme conditions. In some places, life can survive in near-boiling heat or near-freezing cold, high pressure or high salt, as well as environments steeped in acids, alkalis, metals or radioactivity. If life can survive those extreme conditions, it is reasonable to think that life exists on mars & other moons.

What is direct harvesting?

Direct harvesting can be referred to take a species out of it's natural environment. We need to directly harvest various organisms for resources that support our population growth and maintenance. However, direct harvesting such as overfishing and the use of drift nets has threatened the aquatic biodiversity on a large scale. Likewise, we have also hunted and poached endangered animals to the point of near extinction.

Direct harvesting can be stopped by controlling fishing by making strict laws and apply them. We can also restrict the entry of people in the areas where large population of animals are present as reserve areas.

Answers

All of the following are types of climate occurring along a coastline and are characterized by of precipitation, except Continental Climate

What precipitation means?

Any form of liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. One of the three key phases of the global water cycle is it.

Continental climates are characterized by unpredictable weather patterns and wide temperature variations. The concept of continentality refers to how closely a region's climate resembles that of the interior of a large landmass. This type of climate develops in the mid-latitudes, where no body of water, such as the sea or ocean, regulates temperatures and the dominant wind blows overhead.

Due to the lack of a water body to maintain a milder winter and cooler summer, these areas have colder winters and hotter summers. This is true because rocks and dirt rapidly lose heat and have a smaller heat capacity than water. As a result, the continental climate is generally dry since air masses from distant oceans are lost before they can reach the area.

The Northern Hemisphere, which has the necessary huge landmass for the climate to develop, is where continental climate is most prevalent.

Answers

Cell function is often compared to the operation of a factory or city as Nucleus. It should be compared to a neighborhood. Thus, option C is correct.

What are centrioles?

Centrioles are small, cylindrical cell organelles, present near the nuclei of animal cells. They are involved in formation of spindle fibers at the time of cell division that help in proper separation of chromosomes during cell division. Plant cells do not have centrioles.

Nucleus and ribosomes are present in both animal and plant cells, while cell wall is found only in plant cell. Thus, the organelle in diagram that should be listed under 'animal only' will be 'centriole.'

Therefore, Cell function is often compared to the operation of a factory or city as Nucleus. It should be compared to a neighborhood. Thus, option C is correct.

The four levels of protein structure are primary, secondary, tertiary, and quaternary structure. Review the levels of protein structure by clicking the image below.
Drag each label into the appropriate bin depending on whether it applies to primary, secondary, tertiary, or quaternary structure.

Answers

Proteins are composed of a sequence of amino acids linearly arranged. To accomplish their functions thet must adopt different structures. Primary structure: Amino acid sequence. Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide. Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide. Quaternary structure: The aggregation of multiple polypeptide subunits.

What is the protein structure?

Proteins are molecules composed of several amino acids.

Amino acids are monomers composed of

a central carbon, a hydrogen atom, a carboxyl group (COOH), an amine group (NH₂), and an R group.

The R group is what differentiates one amino acid from another one.

Several amino acids linearly arranged and connected by peptidic bonds compose the polypeptide.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid stabilizes the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the amino acid sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

The primary structure is basically, the sequence of amino acids in the chain. It refers to the amino acid arrangement.

The secondary structure is achieved through hydrogen bonds (between -CO- and -NH- groups), when the polypeptidic chain folds and different regions of the molecule get in touch. The molecule can adopt conformations like the alpha-helix and beta-sheet.

The three-dimensional structure involves a higher folding degree, in a tridimensional space. This level makes the protein even more stable in the environment and capable of accomplishing its functions.

The quaternary structure can be seen when proteins are composed of more than one subunit. The way in which these subunits arrange is the fourth structure.

The hydrophilic R-groups stay permanently in the molecule interior, avoiding interaction with water.

In the image,

Primary structure: Amino acid sequence

Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide.

Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide.
