Answer:
a. Decrease water reabsorption : decrease blood pressure.
b. Decrease peripheral resistance : decrease blood pressure
c. Vasodilation : decrease blood pressure
d. Decrease salt intake : decrease blood pressure
e. Decrease blood volume : decrease blood pressure
f. Vasoconstriction : increase blood pressure
g. Increase peripheral resistance: increase blood pressure
h. Increase salt intake: increase blood pressure
i. Increase blood volume : increase blood pressure
j. Increase water reabsorption: increase blood pressure
Explanation:
Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow. This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance. Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows. This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others. Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure. The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs. Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.What is the function of the synapse? It allows information to go from one neuron to another through neurotransmitters. It allows the nerve impulse to travel within the neuron due to neurotransmitters. It allows the cell body to regulate the activities of the neuron. It allows faster transmission of information through the neuron.
Answer: It allows information to go from one neuron to another through neurotransmitters. :)

together
Explanation:
Mutualism is defined as a relationship that benefits two organisms, or it is defined as a doctrine in sociology where mutual aid is beneficial to society and the individual. An example of mutualism is pollination which is when bees take nectar from flowers and then deposit the nectar on another flower.
If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?
only males
neither males nor females
only females
O both males and females
Answer:
only females
Explanation:
In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.
Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).
N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.

Why it is important to emasculate and bag wheat, oats and groundnut flowers before a cross is made by using another desirable plant.
Answer:
There are no options in this question but it can be answered using general knowledge. The answer is:
In order to prevent self-pollination or natural cross-pollination of the wheat, oats or groundnut flowers.
Explanation:
The flowers of wheat, oat and groundnut plants have something in common, which is the fact that they are all bisexual flowers i.e. flowers that have both male and female reproductive parts. Hence, they tend to undergo self-pollination i.e. transfer of pollen to female reproductive part on the same flower.
To prevent this from occuring when a desirable trait is wanted during crop breeding procedures, a process called EMASCULATION is carried out. Emasculation is the process whereby the stamen (male flower) or pollen of a plant is removed without destroying the female part of the flower. This is done in order to discourage self-pollination in plants with a bisexual flower.
Also, after emasculation, the flowers are bagged in order to prevent natural cross-pollination i.e. to prevent pollens from other plant from being transferred to the stigma of the desired plants in random manner.
Hence, emasculation and bagging is important to make sure the desired plants are still viable for the crop breeding procedure.
Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation? A. GGACTCGATCTTC B. CCACCGTCGATCTTC C. GGACCGTCGATCTTC D. GGACCGTCGATCCTT
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.
Answer: GGACCGTCGATCCTT
Explanation: mutation means change and there is change in the gene sequence

Explanation:
The antidiuretic hormone is one of the hormones released by the hypothalamus (regulator center in the brain) and collected by the posterior hypophysis from where they are then released again to the system. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood pressure. The osmotic receptors are located in the hypothalamus, while the pressure receptors are located in the heart, the aorta, and carotids. The amount of hormone secreted depends on these two aspects. Its function is to keep homeostasis and make kidneys conserve or excrete water to regulate its volume. The antidiuretic hormone stimulates water reabsorption when factors such as dehydration or hemorrhages are causing an increase in blood solutes. It might also stimulate water excretion when solutes in the blood are very low or blood pressure is too high.
Aldosterone is another hormone that acts stimulating the sodium ions reabsorption. This hormone production is controlled by a circuit named the renin-angiotensin-aldosterone system. This system is activated by the decrease of blood supply to the kidney, and hence, the decrease in blood pressure and sodium concentration. These factors cause the release of the renin, a proteolytic enzyme that acts on angiotensinogen producing angiotensin I which is converted into angiotensin II. Angiotensin II is a peripheric vasoconstrictor peptide, that can increase the blood pressure when it is circulating in the plasma. It also stimulates the secretion of aldosterone.
Human actions often break large areas if forest or grassland into small remnant parcels that support fewer individuals and ae far apart from one another. Predict how gene flow, genetic drift, and extinction risk would differ between the original and the remnant populations.
Answer:
Gene flow will be restricted
Gene drift will be higher than in larger populations
Extinction rate will be increased due to the reduction in genetic diversity
Explanation:
Gene flow is defined as the transference of genetic material among populations. In isolated populations, the gene low is null and thereby they have different allelic frequencies, while populations that share genetic material tend to have the same allelic frequencies.
Genetic drift is the change in the allelic frequencies in a population as a result of random sampling. In small populations such as those living in parcels, the genetic drift is higher than in larger populations.
Extinction is the continuous declination in the number of organisms of a particular group (for example, a population or a species), that inevitably leads to the disappearance of this group. In small populations, the likelihood of extinction will be higher than in larger populations, due to the lesser genetic variation and higher genetic drift.

When an enzymatic reaction is in progress, do you expect to see an increase, decrease or no change in each of following: (i) substrate (ii) product (iii) enzyme
Answer:
During Enzymatic reaction, enzymes binds to a substrate to form a which then forms the product.
Substrate: A reactant in an enzymatic or chemical reaction is called substrate. Product: The final outcome or substance after completion of reaction is called product.Enzyme: Enzyme helps to increase the rate of reaction and act as a catalyst.Change in shape of substrate, product and enzymes depends on the temperature outside the optimal range which affect bonding between enzyme and substrate. Enzymes definitely changes their size when bind to substrat and the process is called induced fit which increases the rate of reaction.
During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.
What is enzymatic reaction?A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.
The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.
In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.
Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.

DNA is transcribed to messenger RNA (mRNA), and the mRNA is translated to proteins on the ribosomes. A sequence of three nucleotides on an mRNA molecule is called a codon. As you can see in the table, most codons specify a particular amino acid to be added to the growing protein chain. In addition, one codon (shown in blue) codes for the amino acid methionine and functions as a "start" signal. Three codons (shown in red) do not code for amino acids, but instead function as "stop" signals.
Sort the following ten codons into one of the three bins, according to whether they code for a start codon, an in-sequence amino acid, or a stop codon
AUG, UAG, UAA, UGA, AAA, UGC, AUC, CAC, GCA, ACU
Answer:
start codon - AUG
in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU
stop codon - UAA, UAG, UGA
Explanation:
From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.
Hence, using the attached amino acid chart:
start codon - AUG
in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU
stop codon - UAA, UAG, UGA
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures spiked, we observe temperate forests ____________________, insect herbivory of temperature.
Answer:
The overview of the problem concerned is listed below.
Explanation:
Mostly during Paleocene Eocene Temperature Optimum, we consider temperate vegetation momentarily relocated towards the poles whenever global average surface temperature jumped, bug harvesting temporarily escalated, as well as coral reef crashed.The level of variations in climate or temperature was as sluggish as it is today, which suggests that such past occurrences are likely to overestimate the effects of rising temperatures nowadays.Increase occur in the insect's population due to increase occur in global surface temperature.
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures increase, we observe temperate forests having more population of insects due to favourable temperature for the growth of insects.
The productivity and distribution of forests could be affected due to change occur in the temperature, precipitation and the amount of carbon dioxide in the air. As the temperature increases the population of insects also increases which leads to increase in biodiversity of forest so we can conclude that increase occur in the insect's population due to increase occur in global surface temperature.
