Warm-up: 5 mins of jogging Cool-down: 5 mins of jogging :Type of Activity: Cardiovascular Description of Activity and Time: 10 reps of 1 min wind sprints: Intensity Level: Vigorous :Total Time: 10 mins

Cardiovascular activity is any physical activity that increases the heart rate and causes the heart to pump more oxygen and nutrients to the body. It promotes the circulation of those essential elements throughout the entire body. Examples of cardiovascular activities include running, swimming, cycling, and dancing.

The human body requires six core essential elements in order to maintain optimal functioning: nitrogen, hydrogen, oxygen, phosphorus, sulfur, and carbon.

1. Nitrogen – nitrogen is an essential element of proteins and other molecules, including enzymes, hormones, and DNA. Without nitrogen, the body would not be able to make the proteins it needs to survive.

2. Hydrogen – this element is needed to synthesize fatty acids, which are necessary for proper cell functioning. Hydrogen is also a component of water and helps stabilize other molecules in the body.

3. Oxygen – oxygen is required for energy production in the body and helps maintain the balance of water and other elements in the body.

4. Phosphorus – phosphorus is essential for energy production and is a component of DNA and cell membranes.

5. Sulfur – sulfur is a necessary component of several amino acids, which are used to build proteins in the body.

6. Carbon – carbon is the basic building block for all organic compounds in the body, including organic molecules such as carbohydrates, lipids, and proteins. Carbon is also critical for the metabolism of energy-producing molecules.

Ee x ee would be the parental cross between a heterozygous (Ee) dog and an ee dog, resulting in 50% of the progeny having pointed ears (Ee) and 50% having floppy ears (ee).

A heterozygous dog (Ee) and a dog with floppy ears (ee) would be a parent cross of Ee x ee. This is due to the fact that the floppy-eared dog has two recessive (e) alleles as opposed to the heterozygous dog's single dominant (E) and one recessive (e) gene for ear shape. The Punnett square predicts that when these two dogs are crossed, 50% of the progeny will have pointed ears (Ee) and 50% will have floppy ears (ee).

Explanation:

ATP (Adenosine tri-phosphate) is an important molecule found in all living things. Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just like a rechargeable battery. When it’s fully charged, it’s ATP. When it’s run down, it’s ADP. However, the battery doesn’t get thrown away when it’s run down–it just gets charged up again.

A field that was formerly planted with crops will eventually be stripped of its native flora and planted more with crops. Shifting cultivation systems are well-established and stable cycle between periods of cropping.

Ecological succession is the process in which a town's species or habitat mix changes over time. Unless a "climax community," such as a big forest, is reached or a major disruption, like a fire, occurs, these communities start replacing one another.

Two different succession patterns exist. Primary succession is first. Primary succession takes place at a place where there has never been a community before. Freshly exposed rock areas, dunes, and lava flows are examples of places wherein primary succession takes place.

The mutation is in the third position of the first codon, where "C" replaced "A", resulting in the codon "UAC" instead of "AUC".

A mutation is a change that occurs in the DNA sequence of an organism. It can be caused by errors during DNA replication, exposure to mutagens such as radiation or chemicals, or spontaneous changes that occur over time.

Considering the given mutated DNA sequence:

mRNA sequence: AUG UGG ACC UGA CUA

Amino acid sequence: Met Trp Thr Stop Leu

The effect on the protein depends on the specific amino acid that is affected by the mutation. Referring to the chart, the codon "AUC" codes for the amino acid Isoleucine (Ile), and the mutated codon "UAC" codes for Tyrosine (Tyr). Therefore, the mutation results in a substitution of Isoleucine with Tyrosine at the first position of the polypeptide chain.

This is a substitution mutation, also known as a point mutation. It occurred at a single nucleotide position and changed the corresponding codon from one amino acid to another.

One reason the membrane proteins may not go where the Davidson-Danielli model predicted is due to the fluidity and dynamic nature of the lipid membrane.

This model assumed that the lipid membrane was static and that proteins were fixed in their positions. However, it is now understood that the lipid membrane is constantly in motion, with lipids and proteins able to move laterally and even flip-flop between the two leaflets of the membrane.

As a result, membrane proteins may not be fixed in the locations predicted by the Davidson-Danielli model and may instead be more distributed or even inserted into the lipid bilayer.

Additionally, the Davidson-Danielli model did not account for the diversity of membrane proteins and their different structural and functional properties, which can also influence their localization within the membrane.
