2) Micah and Taylor investigate the effect of tap water and spring water on the growth of plants.

They grew two plants of the same type and size in separate containers. Every three days, they

added the same amount of tap water to one plant and the same amount of spring water to the

other. Describe an action that would best improve the reliability of their results?

Answers

Answer 1

Answer:

To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.

Second, the experiment should be carried out under greenhouse conditions.

The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.

By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

Cheers!

A. Mitosis

B. Meiosis

C. Apoptosis

D. Phagocytosis

Answer:

A

Explanation:

Mitosis is a type of cell division which takes place in living  organism during growth and development.Therefore it is ensures  the regenerations of cells and tissues during healing.

Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.

In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.

Keloids  is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating  patch skin

Blonde hair (represented as b) is a recessive trait. If Julie has blonde hair, which of the following could have been her parents' genotypes?
A. Bb, bb
B. BB, bb
C. BB,BB
D. Bb,BB

Answers

I think its Bb, bb because if julie has blonde hair then it's most likely to be Bb, bb

If Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

What do you mean by Genotypes?

Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for specific studies in order to express some genetic characteristics.

According to the context of this question, if the trait of Blonde hair is recessive in nature. This means that both the alleles of this gene are recessive, i.e. bb.

Now, if Julie has blonde hair, which means both alleles are recessive. So, the genotypes of parents of Julie are either homozygous recessive or heterozygous in nature. This characteristic is well determined by option 1.

Therefore, if Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

Natural selection states that complex organisms evolved through random mutations alone. True or False?

Answers

Answer:

False.

Explanation:

This statement is false because organisms don't evolve - populations do. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population. However, because mutation rates are low relative to population growth in most species, mutation alone doesn't have much of an effect on evolution.

what is cardiovascular arrest...?
explain...?

Answers

Answer:

Cardiac arrest is the abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease. It can come on suddenly, or in the wake of other symptoms. Cardiac arrest is often fatal, if appropriate steps aren’t taken immediately.

Each year in the United States, more than 350,000 cardiac arrests occur outside of a hospital setting.

These two distinct heart conditions are linked. Sudden cardiac arrest can occur after a heart attack, or during recovery.  Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks do not lead to sudden cardiac arrest. But when sudden cardiac arrest occurs, heart attack is a common cause. Other heart conditions may also disrupt the heart’s rhythm and lead to sudden cardiac arrest. These include a thickened heart muscle (cardiomyopathy), heart failure, arrhythmias, particularly ventricular fibrillation, and long Q-T syndrome.

Cardiac arrest is reversible in most victims if it's treated within a few minutes. First, call 911 for emergency medical services. Then get an automated external defibrillator if one is available and use it as soon as it arrives. Begin CPR immediately and continue until professional emergency medical services arrive. If two people are available to help, one should begin CPR immediately while the other calls 911 and finds an AED.

Sudden cardiac arrest is a leading cause of death – over 320,000 out-of-hospital cardiac arrests occur annually in the United States. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.

1.What is meant by Plasma therapy ? Is it a remedial treatment for Coronavirus? Express your answer with valid points

Answers

Answer:

It is a therapy that involves the use of plasma from recovered patients (which is composed of antibodies against the virus)

Explanation:

The immune system of patients already recovered from viral diseases naturally generates defensive molecules that circulate in the blood. These molecules are known as 'antibodies', and they are localized in the plasma of the blood, which is composed of coagulation factors, albumin, fibrinogen and, of course, antibodies. These antibodies bind to specific viral antigens in order to promote their neutralization and destruction. In consequence, the plasma from recovered patients contains particular antibodies that may be used to treat specific diseases.

pros and cons of genetically modifying the animals people eat? ​

Answers

Answer:

Explanation:

   GMOs are food items that have been made using genetic engineering techniques. ...

   GMO foods are easier and less costly for farmers to grow, which makes them cheaper for the consumer. ...

   The main concerns around GMOs involve allergies, cancer, and environmental issues — all of which may affect the consumer.

The advantages include improved human health, increased food production, reduced environmental impact, and so on. There is a risk that new diseases originating in genetically engineered animals will be transmitted to non-genetically engineered animals, including humans.

What is genetic engineering?

Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

This could be as simple as changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a new segment of DNA.

Gene therapy aims to modify genes in order to correct genetic flaws and thus prevent or cure genetic diseases. The goal of genetic engineering is to modify the genes in order to improve the organism's capabilities beyond what is normal.

The benefits include improved human health, increased food production, and reduced environmental impact, among other things. There's a chance that new diseases originating in genetically engineered animals will spread to non-genetically engineered animals, including humans.

Thus, these are some pros and cons of the genetically modified animals.

Answers

Answer:

The correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia

Explanation:

Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.

A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.

Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.

Explanation:

The question asks to pick the question that is least likely to lead to a scientific investigation based on these findings.
