B. Neurotransmitters send signals from neuron to neuron.

Explanation:

Lack of neurotransmitters may cause problems because neurotransmitters send signals from neuron to neuron.

The lack of neurotransmitters cause problems because neurotransmitters send signals from neuron to neuron. Therefore, option (B) is correct.

A neurotransmitter is a molecule that a neuron secretes to influence another cell at a synapse. Another neuron, a gland or muscle cell, or the target cell, could be the cell that receives the signal.

Your body cannot function without chemical messengers called neurotransmitters. Chemical signals, or "messages," are carried from one neuron (a nerve cell) to the next target cell by them. The following objective cell can be another nerve cell, a muscle cell or an organ.

Answer:

Option -2 Palm oil produces more quantity of oil for a similar amount of land than any other plant is the correct answer.

Explanation:

firstly,

Edible vegetable oil that is gathered from the mesocarp i.e., the reddish pulp of the fruit of the oil palms is known as palm oil. The oil is used in food manufacturing, making beauty products, and as biofuel.

Palm oil has many advantages that are listed below-

Besides all these positive ways one of the important uses of palm oil farms is that it helps in conserving natural resources.

Oil palms are significantly more efficient than any other oil-producing crops. A single hectare of land can produce about 4.17 metric tons of sunflower oil, 0.16 tons of ground oil, and 0.39 tons of soybean oil. this means that significantly less land has to clear to meet demands for vegetable oil while other crops require at least five times more land to produce the same volume of oil as oil palms.

Conclusion-Palm oil produces more oil per land area than any other equivalent vegetable oil crops.

hence, the second option that says a similar amount of land produces more oil in the case of palm oil is the correct answer.

Answer:

The correct answer is -

A. genotype ration = 1/1 or 100% of Aa.

B. phenotype = all smooth-seeded.

Explanation:

According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA

gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.

Punnett square:

       A          A

a      Aa       Aa

a      Aa       Aa

In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.

And phenotypically 100% chances of the smooth seed plants.

Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+.  A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.  The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.  The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.

Answer:

punctuated equilibrium

Explanation:

The punctuated equilibrium theory is a model of evolution by bursts of speciation, which was proposed by the paleontologists Niles Eldredge and Stephen J. Gould (1972). The theory of punctuated equilibrium states that evolution is characterized by rapid changes followed by longer periods of stasis where little observable evolution seems to occur judging from the fossil record. The punctuated equilibrium theory does not propose that Darwin's evolutionary gradualism is wrong, but this theory suggests that important evolutionary changes occur in short periods of time that are linked to speciation events. In consequence, fossils record does not represent transitional forms because of their small population size compared to the observed in stasis periods.

Physical activity will increase cardiac output. Therefore, the correct option is "B".

Cardiac output is related to the heart's health. It tells the amount of blood pumping in and out of the chambers of the heart. This mechanism helps in circulation of the blood throughout the body. The blood can be oxygenated and deoxygenated. The circulation of blood to the vital organs and the main organ brain is circulated through this process.

The calculation of the cardiac output is oxygen consumption in ml per minute is divided by the oxygen concentration in arterial blood and minus oxygen concentration in venous blood in the body.

Therefore, the calculation of the cardiac output helps in the identification of the heart's health.

Answer:  The scientist was repeating the experiment to improve the validity of her data.

Explanation:

The scientific method involves the observation of natural phenomena and then the postulation of hypotheses and their testing by experimentation. The knowledge we have represents scientific hypotheses and theories supported by observations and experiments (empirical method).

Experiments are performed to support/validate or refute one or many hypothesis. Several experiments provide insight into cause-and-effect by demonstrating what result occurs when a particular factor is manipulated.

A scientific hypothesis is an acceptable proposition that has been formulated through the collection of information and data, although unconfirmed, serves to provide an alternative answer to a scientifically based problem. Also when a research work is carried out, a conclusion should be drawn, which in these cases is an argument or statement that synthesizes the work done. The main ideas are taken and the research is summarized, explaining in the author's own words the reason for the results obtained. In the case of a discussion, the personal point of view of each of the members that participated in the experiment are exposed.

Since the scientist repeated the previous experiment to improve the validity of her data, that justifies the fact that she skipped the hypothesis and experiment. With the first results of the experiment, I formulate a conclusion. Then, with other results of the same experiment, he formulated another conclusion. So there is no need to repeat the experiment, because it is the same.

The directions for making a protein are carried by DNA. Option B.

Genes are usually expressed in form of proteins and proteins are sequences of different amino acids. The amino acids are synthesized from genetic codes present in mRNA. mRNA is synthesized during transcription from DNA templates.

In other words, the sequence of amino acids in proteins is dictated by the sequence of nucleotides on mRNA. Whereas, the sequence of nucleotides on mRNA is dictated by the sequence of nucleotides on the coding strand of DNA that serves as the templates for the synthesis of the mRNA.

In summary, DNA is indirectly responsible for the sequence of amino acids present in proteins.
