Which of the following is FALSE regarding hypotheses? a. They can only be tested with laboratory experiments
b They should make predictions
c. They are testable
d. They are accepted or rejected after data is collected and analyzed

Answers

The hypotheses serve as a first step in the investigation, which will seek to prove or refute their validity depends on submitting to several tests, based on the elaborated theories, therefore they can only be tested with laboratory experiments is FALSE.

What are hypotheses?

It is a provisional formulation, since when tested it becomes a verified or demonstrated statement.

The search for possible answers to the hypothesis, provided that they are based on procedures and theories that can be tested in the field, so that they can be reproduced as many times as necessary if the same conditions are met.

Therefore, we can conclude that the hypotheses are totally provisional approaches, which will be proven or discarded through research, therefore they can not only be tested with laboratory experiments.

Jerome also had blood work done to confirm the MI. The presence of troponin, or cardiac enzymes such as CK-MB, are a positive indicator of an MI. Why is their presence at higher levels in the blood indicative of an MI? a. They are by-products of aerobic metabolism and if they are present in higher amounts in the blood it shows that the myocardium is working harder.
b. They are substrates for aerobic metabolism and if increased in the blood show that the cardiac muscle is not functioning normally.
c. These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
d. They are by-products of anaerobic metabolism (glycolysis) and if increased indicate that the heart is not receiving oxygen.

Answers

Answer:

c.These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.

Explanation:

  • When there is a decreased blood flow to the heart or if a particular part of the heart stops working then this is known as myocardial infarction (MI) and due to this the heart muscle gets damaged.
  • There are several biomarkers that are used to evaluate the functioning of the heart and these are known as cardiac markers, an example of this is Ck-MB which is an isoform of creatine kinase.
  • The CK-MB isoform is found in the cytosol of the heart muscle cells and it plays a role in causing the movement of high energy phosphates in and out of the mitochondria.
  • If there is a damage to the heart muscle cells which usually occurs following a myocardial infarction CK-MB levels elevates in the blood for a short period of time and this indicates MI.

Answers

Answer:

Abiotic factors can be described as the non-living components of an ecosystem. Biotic factors can be described as the living components of an ecosystem.

Abiotic factors include all the non- living components such as the weather, climate, temperature, soil, water of an area.

Biotic components include all the living organisms like the plants, animals, microorganisms of an ecosystem.

Hence, abiotic factors best describe the temperature and weather conditions of an organism's environment.

How are the reactants represented in the chemical equation for photosynthesis? © 6CO2 + O2
6CO2 + 6H20
o CoH12O6 + 602
O C6H12O6 + 6H20

Answers

Answer: The reactants are represented in photosynthesis equation as follows:

6CO2 + 6H20 --> C6H12O6 + 6O2

Explanation:

During photosynthesis, six molecules of Carbondioxide (6CO2) reacts without six molecules of water (6H2O) to form six molecules of oxygen (6O2) and a molecule of glucose (C6H12O6).

Answers

The right option is; C limestone

Limestone is the nonmetallic mineral that is used as a building material and also in the manufacture of steel.

Limestone is an abundant naturally occurring rock of marine and fresh water sediments that is primarily composed of high levels of the mineral calcite (CaCO3) with small quantity of other minerals such as quartz (silica), pyrite (iron sulphide) etc. Limestone is used for a wide range of industrial and manufacturing uses. It is used as a building material and it is also an important raw material used in manufacturing iron and steel.

The answer is C Limestone.

How do proteins play an important role in the mating of japanese beetles? a. by storing lipids for future use by the reproductive cells
b. by sending and detecting chemical messages
c.by making hormones tha increase the drive to mate
d. by breaking down proteins for energy used in reproduction

Answers


The answer is B.

The female beetle releases proteins as pheromones and these are detected  by protein receptors on the male beetles. The proteins play the role of guiding the male to the female for mating purposes.

Pheromones are a type of hormone, but unlike most other hormones, they are ectohormones, that is they act outside the body of the organism that is secreting them and impact the behavior of another individual. Hormones usually only affect the organism or individual that is secreting them.

B. the female beetle sends out proteins as hormones, which are then picked up by receptors on the male beetles.
