S. Give three reasons to explain why transpiration occurs mainly through leaves
6. Explain how sunken stomata lower the rate of transpiration
11
with
ftri
Answer:
Due to stomata.
Explanation:
Transpiration occurs mainly through leaves because of the presence of stomata n the lower side of the leaves. Transpiration refers to the loss of water from the body of plants so leaves has small pores which is used by the plant to regulate internal temperature. Sunken stomata lower the rate of transpiration because it is not directly exposed to the surface which protects the escaping water vapor due to air.

In rabbits, black fur (B) is dominant to white fur (b) A purebred black furred male is bred with a female that had the recessive white fur
Answer:
BB x bb
Bb
Bb
Explanation: When a purebred dominant trait is bred with a purebred recessive trait then the offspring will always have the dominant and recessive trait.
1) All of the following are examples of an asexual reproduction except
a) Cloning technique b) Forming zygots
c) Runners technique I
d) Tuber technique in the potato
Answer:
b) Forming zygots
Explanation:
A zygote can be defined as a eukaryotic cell formed by the fusion of gametes during sexual reproduction. In general, a zygote is a diploid (2n) cell produced by the fusion of two haploid (n) gametic cells (eg., in mammals, sperm and egg cells). In multicellular organisms, the zygote is the first stage of development, which will give rise to an adult organism as it divides and grows. A zygote cell can be considered as a pluripotent stem cell because it differentiates into all cell types.
Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

the dna structures
Answer:
Each DNA strand is composed of nucleotides—units made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base. Each strand of DNA is a polynucleotide composed of units called nucleotides. A nucleotide has three components: a sugar molecule, a phosphate group, and a nitrogenous base. Explanation:

What regulates breathing rate and how does the body sense when to breath?
Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
What percent of energy is transferred from the sun to the level indicated? (3 points)
50 percent
100 percent
90 percent
10 percent
Answer:
It can
be explained with the help of ten percent law which
states that only 10 percent of the total energy available
at any trophic level is passed on the higher trophic level .
Most of the energy is lost as heat or is used in the
process of cellular respiration.

How is dopamine involved in drug addiction?
1) drugs change dopamine into another neurotransmitter.
2) drugs cause the reabsorption of dopamine.
3) drugs decrease dopamine levels in the brain.
4) drugs increase the level of dopamine in the brain
Answer and I will give you brainiliest
Answer:
The correct answer is - option D.
Explanation:
When an individual takes drugs such as heroin, nicotine, cocaine and methamphetamine increases or promotes the neurochemical reaction that increases the amount of dopamine which is a primary factor in addiction that is secreted by neurons in the brain's reward center.
Higher dopamine levels lead to pleasure in the mind of an addict and it makes people forget the pain or stress and gives immense pleasure.
Thus, the correct answer is - option D.

In normal cells the amino acid phenylalanine attaches to tRNAs with the anticodon AAA. The enzyme aminoacyl-tRNA synthetase catalyzes the reaction that attaches the amino acid to the correct tRNA. Assume that a mutation occurs in the aminoacyl-tRNA synthetase enzyme and causes it to attach lysine instead of phenylalanine to tRNAs with the anticodon AAA. What will be the consequence of this mutation for the translation process
Answer:
Aminoacyl-tRNA bond is hydrolyzed.
Explanation:
The consequence of this mutation for the translation process is the hydrolysis of aminoacyl tRNA bond occur. If the incorrect amino acid is attached to other molecule as a result of this reaction, the aminoacyl-tRNA bond is hydrolyzed. This incorrect binding of amino acid occur because of mutation in the aminoacyl-tRNA synthetase enzyme that leads to its hydrolysis.

Some people's earlobes dangle or flap unattached, while others don't. This trait is genetically determined. Use the genetics simulation to explore the genes that determine whether earlobes are attached or unattached. One trait is dominant and the other is recessive. See what happens when you cross parents with different genetic combinations. Follow the specific instructions for each trial.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..
