Activities like walking, jogging, running are promotes cardiovascular fitness. Sports such as soccer, basketball, squash and tennis may also improve your cardiovascular fitness.
What is cardiovascular fitness?
A lot can be learned about your health and the likelihood of certain health outcomes from your cardiorespiratory fitness, or CRF. Simply put, CRF measures how effectively your body transfers oxygen to your muscles and organs during prolonged exercise.
According to the given question:
You can exercise without becoming overly exhausted because your heart, lungs, and blood vessels are in good shape. Walking, jogging, biking, dancing, running, and riding a bike are all examples of exercises. Swimming over long distances is a great way to work your heart.

if there is 8 g of a substance before a physical change, how much will there be afferwards
Answer:
The correct answer is 8 g.
Explanation:
During a physical change, the identity of the substance does not change, because no chemical reaction occurs. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.

Answer:
humidity and evaporation
Explanation:
Provide an example of how your body could maintain homeostasis in response to detecting that the body temperature was falling below 98.5 degrees.
Answer:
Our body produces heat energy.
Explanation:
When our body temperature decreases than normal range, our body produces heat to maintain internal heat in the normal range. Our internal body temperature is regulated by hypothalamus which is a part of our brain. The hypothalamus regulate the temperature and take actions to maintain it in the normal range of temperature which is about 37°C. If our body temperature is too low, the hypothalamus order to the body to generates heat energy and maintains heat in the normal range. The sweat glands remain inactive in order to prevent heat losses.
which of the following organisms has the simplest cellular structure? a. bacterium b. earthworm c. mushroom d. sunflower
Bacteria will have the simplest cellular structure. So the correct option is A.
What are prokaryotic cells?A cell type without a genuine nucleus or membrane-bound organelles is referred to as prokaryotic. All the other types of life are eukaryotic, whereas organisms in the categories of Bacteria and Archaea are centered on the prokaryotic cell.
Prokaryotic species, on the other hand, are exceedingly prevalent and account for a large portion of the biomass on Earth.
Unicellular organisms are those that have prokaryotic cells. We refer to them as "prokaryotes." A prokaryotic cell may operate as a live creature thanks to a number of factors. Prokaryotes have a cell membrane covering them at first.
With the help of this membrane, they may engineer a particular environment for metabolic processes within the cytosol. Second, these cells contain both ribosomes and free DNA.
Even though ribosomes are organelles, a plasma membrane does not enclose them.
Therefore the correct option is A.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.
2. What is the growth rate (r) of the alligator population during 2007?
Answer:
1. 260
2.
3. drought
4. babies born
6. carrying capacity
7. population density
8. logistic growth

How is food digested inside me ?
Answer:
After you swallow, peristalsis pushes the food down your esophagus into your stomach. Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.

During translation, tRNA adds the correct amino acid to the growing protein, following the mRNA codon sequence. Tryptophan, Lysine, Leucine, Tyrosine.
What is translation?Translation is the stage in protein synthesis that follows transcription, and occurs in the cytoplasm.
When mRNA leaves the nucleus and moves to the cytoplasm, it meets a free ribosome that is the primary structure for protein synthesis. Ribosomes are composed of two subunits of rRNA associated with different tRNA that carries amino acids.
The ribosome reads mRNA in the 5' to 3' direction, and, according to the codons that are being readen in mRNA, tRNA transfers the correct amino acids to build the polypeptide chain.
Let us remember that the codon is the sequence of three nucleotides present in mRNA. The molecule carriesa a start codon and stop codons.
Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.
The protein is synthesized from the amino terminus to the carboxy terminus.
In the example,
DNA mRNA tRNA Amino Acid
ACC UGG ACC Tryptophan
TTC AAG UUC Lysine
GAT CUA GAU Leucine
ATA UAU AUA Tyrosine

WHAT IS The 2nd phase of mitosis
Answer:
When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.
