6th grade student measured his heart rate at 94 beats per minute every minute every morning at the same time for two
Weeks. In his report he claimed he proved that 6th grader's hearts beat 94 times per minute. What is wrong with his
Report?

A. Human hearts do not beat that rapidly.

B He should have taken his heart rate many times over two weeks.

C. 6th graders hearts do not beat that slowly.

D.The student's sample size is too small to prove his claim.

Answers

Answer 1

Answer:

its A

Explanation:

Its impossible for a human to have a heart beat of 94 each minute

Answer 2

The statement that represents a wrong concept in his report is as follows:

Human hearts do not beat that rapidly.

Thus, the correct option for this question is A.

What is Heart rate?

Heart rate may be defined as a mechanism that significantly involves the number of times the heart beats within a certain time period generally in a minute. In a more simple sense, it may be characterized as the number of contractions of the heart per minute.

According to the context of this question, the normal rate of humans usually ranges from 60 to 100 beats per minute. But being a student of 6th standard, it is too higher because it is ranging from 60 to 80 per minute for that group of children specifically with respect to the capability of their cardiovascular stength.

Therefore, the correct option for this question is A.

From the illustration, it can be said that the age of the rock layer is the same in the four locations of index fossil 1.

Age of fossil

It is a measure of how long a material has been fossilized.

Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.

Only index fossil 1 is found in all the four locations as shown in the image. Hence, one can as well infer that the rock layers in all these four locations are of the same age.

What is the target heart rate zone?

The target heart rate is typically represented as a percentage of your maximum safe heart rate, typically between 50 and 85 percent.

The highest rate is determined by deducting your age from 220. Therefore, the maximum heart rate for a 50-year-old is 220 minus 50, or 170 beats per minute.

Anatomical adaptations involve every change in the organism's external structure. Option B. A feature of the organism's body that helps it survive and reproduce.

What is an anatomical adaptation?

Anatomical adaptations are changes in the external structure of the organisms that help them survive and reproduce in a certain environment.

These adaptations allow the organisms

to camouflage if necessary (to scape from a predator or to hunt their prey, for instance),

to protect themselves by imitating dangerous species' colors and shapes,

to develop special structures needed to feed and move in that specific environment.

There are other two types of adaptations apart from anatomical ones. These are physiological and behavioral adaptations.

Options

A. a system present within the organism that allows it to perform a biochemical reaction ⇒ This is a physiological adaptation

B. a feature of the organism's body that helps it survive and reproduce ⇒ This is an anatomical adaptation

C. a response from the organism that changes it's behavior to help it survive and reproduce ⇒ This is a behavioral adaptation

Muscles function by producing force and motion and are primarily responsible for:

1. Locomotion.

2. Maintaining and changing body posture.

3. Circulation of blood cells throughout the body.

4.Movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

Answers

An earthworm's body plan consists of all, EXCEPT  pores in the skin for food to move in and a stomach in each segment. Thus, option "B" is correct.

What is an earthworm's body plan?

The physique of the earthworm is segmented which appears like numerous tiny rings combined or merged collectively. The earthworm is made of around 100-150 segments. The segmented body portions deliver significant organizational purposes.

Segmentation can help the earthworm move. Each segment or piece has muscles and bristles named setae. The bristles or setae support the anchor and govern the worm when stirring over the soil. The bristles grasp a segment of the worm definitely into the ground while the other portion of the physique projects forward.

The earthworm uses parts to either contract or relaxes self-sufficiently to source the body to grow in one area or contract in other areas. The division supports the worm to be supple and sturdy in its drive. If each section stimulated collectively deprived of being self-governing, the earthworm would be stationary.

Thus, option "B" is correct.

When a protein denatures, which type of bonding is effected?

Answers

Answer:

When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).
