Biology
1 answer:
Marizza181 [45]2 years ago
6 0

Answer:

* Glucose may cause an increase in bacterial growth - HYPOTHESIS

* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION

* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION

* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS

Explanation:

In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.

According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:

- Glucose may cause an increase in bacterial growth is a HYPOTHESIS

- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION

- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION

- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS

Which of the following statements about cardiac muscle is true? a. Cardiac muscle is like smooth muscle, because smooth muscle h
Aleonysh [2.5K]

Answer:

c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.

Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.

Which of the following is an important exception to the central dogma of molecular biology? a) Proteins are responsible for most
iogann1982 [59]

Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

  • Replication
  • Transcription
  • Translation

<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

<em>The correct option is b.</em>

Summarize the four steps to natural selection
Anna11 [10]

Overproduction - An organism gives birth to too many children

Genetic Variation - The offspring each have genetic differences in appearance, behavior, etc

Struggle to Survive - Offspring must fight in order to gain essential resources (food, water, mates, etc)

Successful Reproduction - Organism produces offspring with beneficial adaptations that aid in survival
