Answer:
The correct answer is - 20.
Explanation:
Respiratory rate is the number of total breaths that occur in a minute. The breathing includes respiratory movements of expansion and contraction of the thoracic cavity or chest cavity.
The calculation of the respiratory at rest can be performed by counting the total number of rising or falling of the chest in a minute. The normal range of respiratory of a healthy adult is between 16 to 20 per minute however it depends on factors like age, medical conditions. Above 25 breaths per minute is considered as elevated respiratory.

supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?
Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.
in gene cloning, what is the next step after the vector and chromosomal dna are cut with a restriction enzyme?
The egg develops into an embryo that contains the same genes as the cell donor. The embryo is then implanted in the uterus of an adult woman to grow.
To make a clone, scientists transfer DNA from an animals somatic cell into an egg from which the nucleus and DNA have been removed. Isolating the gene of interest is the first step in isolating the gene of interest for cloning. This can be done by isolating the DNA from the cell that contains it and cutting it out with specific restriction enzymes. Restriction enzymes are bacterial enzymes that cut DNA at specific sequences. Molecular cloning refers to the isolation of a DNA sequence from any species, often a gene, and its insertion into a vector for propagation, without alteration of the original DNA sequence. The purified DNA and the vector of interest are cut with the same restriction enzyme. This gives us the excised piece of DNA and the excised vector, which is now open.

3. Explain how energy flows through this food chain.
Answer:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Answer:
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. The organisms that consume the producers are herbivores: the primary consumers.

Why do some scientists believe that dinosaurs were warm blooded?
Answer:
Some paleontologists think that all dinosaurs were 'warm-blooded' in the same sense that modern birds and mammals are: that is, they had rapid metabolic rates. ... Some scientists think that very big dinosaurs could have had warm bodies because of their large body size, just as some sea turtles do today.
Explanation:
Hope this will help you
Some scientists believe that dinosaurs were warm-blooded because of evidence from their fossilized bones, growth rates, and the presence of features similar to modern warm-blooded animals.
The belief that dinosaurs were warm-blooded is based on several lines of evidence. First, studies of fossilized dinosaur bones have revealed features such as Haversian canals, which are characteristic of fast-growing, metabolically active animals. This suggests that dinosaurs had high metabolic rates similar to warm-blooded animals.
Second, researchers have analyzed the growth patterns in dinosaur bones and found that they exhibit characteristics of rapid growth, which is consistent with the growth rates observed in warm-blooded animals. Slow-growing reptiles, on the other hand, show different growth patterns.
Furthermore, some dinosaurs show evidence of insulation in the form of feathers or other types of integumentary structures. These structures would have provided insulation and helped regulate body temperature, similar to how feathers function in modern warm-blooded birds.
Additionally, the presence of large predators among the dinosaur species suggests an active and energetic lifestyle that is more characteristic of warm-blooded animals than cold-blooded reptiles.
While these pieces of evidence suggest that dinosaurs were warm-blooded, it is important to note that the debate among scientists is ongoing, and there is still no consensus. The study of dinosaur physiology is challenging due to the limited information available from fossil remains. Nonetheless, these lines of evidence contribute to the hypothesis that some dinosaurs may have exhibited warm-blooded characteristics.

What function would immediately cease if the ribosomes of a cell were destroyed?
A. exocytosis
B. active transport
C. ciliary beating
D. protein synthesis
E. osmosis
Option D. protein synthesis function would immediately cease if the ribosomes of a cell were destroyed.
Ribosomes are important organelles that are responsible for protein synthesis within cells.
These organelles are made up of ribosomal RNA (rRNA) and protein and can be found in both prokaryotic and eukaryotic cells.
Ribosomes play a critical role in the synthesis of proteins by translating the genetic information encoded in mRNA (messenger RNA) into a sequence of amino acids.
Ribosomes are responsible for reading the information encoded in mRNA to assemble the corresponding protein.
Ribosomes read the mRNA in groups of three nucleotides called codons and match each codon with the appropriate amino acid.
The ribosome then links each amino acid together in the proper sequence to form the protein.
This process is known as translation and it cannot occur without functional ribosomes.
So, if the ribosomes of a cell were destroyed, the process of protein synthesis would be immediately halted.
As a result, the cell would not be able to synthesize any new proteins, which are essential for numerous cellular functions.
This would have a cascading effect on the cell, causing a wide range of physiological processes to cease functioning properly.
Therefore, option D) Protein synthesis is the correct answer.

1-What are some ways in which metamorphosis helps the animals that undergo it?
Answer:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. In biology, metamorphosis is the process by which an animal develops continually, after birth or hatching. This involves the change in body structure; both internal and external features, regulated by hormones. Metamorphosis is occasionally accompanied by changes in the animal’s behaviour, physiology and biochemistry.
Explanation:
During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. They change color during metamorphosis as well. The salmon must return to fresh water in order to spawn (breed). Fish that live in the ocean as adults but spawn in fresh water are anadromous. Lampreys go through a period of metamorphosis

It helps the eye to focus by bending the incoming light onto the lens, which in turn focuses it onto the retina at the back of the eye. While the cornea undergoes age-related changes like a loss of nerve cells, it does not lose its elasticity as we age. Instead, the lens located behind the pupil undergoes a loss of flexibility which makes it difficult to change shape, resulting in the condition known as presbyopia.

The size P of a certain insect population at time t (in days) obeys the function P(t) = 500 e 0.04t (a) Determine the number of insects at t=0 days. (b) What is the growth rate of the insect populatio
Answer:
(a) When t=0, we have p(0) = 500 e^(0.04*0) = 500 e^0 = 500(1) = 500. Therefore, there are 500 insects at t=0 days.
(b) The growth rate of the insect population is given by the derivative of the function p(t): p'(t) = 500(0.04)e^(0.04t) = 20e^(0.04t). This means that the growth rate is not constant, but rather it increases as time t increases. For example, at t=1 day, the growth rate is p'(1) = 20e^(0.04*1) = 20e^0.04 ≈ 21.64. This means that the insect population is growing at a rate of approximately 21.64 insects per day at t=1 day.
