During what part of the life cycle can an amphibian have both gills and lungs?

Answers

Answer 1
Answer: Hi there!

In the Juvenile (tadpole) stage, amphibians look somewhat similar to a fish. They however cannot have gills and lungs at the same time. 

Hope this helps!

Once M’Kenna’s small intestine healed, she started eating foods with dairy again and these foods no longer made her sick. Lactase is an enzyme that helps break down foods with dairy.

Which of the following is a disadvantage of using biopower?A. It requires mass production of crops.
B. It is readily available in most places.
C. It produces net-zero emissions.
D. It is biodegradable

Answers

Answer:

A. It requires mass production of crops.

Explanation:

Of all the options the only one that represents a disadvantage is that biopower requires mass production of crops because it could cause loss of biodiversity, degradation of soil quality, soil erosion, food toxicity (due to pesticide residues) and pollution ( use of fossil fuels for agrichemical manufacture, farm machinery and long-distance distribution).

The fact that it is readily available in most places, produces  net-zero emissions and  is biodegradable are all advantages.

I hope you find this information useful and interesting! Good luck!

Answer:

What are some questions that biologists might ask about the living things they study?

Explanation:

Five fundamental questions in biology ...

1) The origin of life.

2) The mechanisms of evolution.

3) The control of the size, both of the organs and of the living beings.

4) The functioning of the brain.

5) Aging.

Biologists might ask some questions about the living organisms they study. These questions include, but not limited to:

  • What group of living organism do they belong to? Is it a plant, animal, protozoan, fungi or moneran?
  • How complex is the organisms' body? is it multicellular or unicellular?
  • How do the organisms feed? is autotrophic or heterotrophic?
  • How do the organisms reproduce? sexual, asexual, or both?
  • How do the organisms get energy? aerobic or anaerobic?
  • How do the organisms move?
  • How do the organisms grow?
  • How do the organisms get rid of waste products from their systems?
  • How long do the organisms live? What is their life cycle like?
  • How do they interact with the biotic and abiotic components of their environments?
  • What kind of habitats do they live?
  • What role do they perform in their habitats?

All these questions and more might be asked by Biologists about the living organisms they study.

Which two parts of sedimentary rock formation include the breakdown and carrying away of existing rock?cementation and erosion
compaction and cementation
deposition and compaction
erosion and weathering

Answers

The two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock are erosion and weathering. Thus, the correct option for this question is D.

What do you mean by Weathering?

Weathering may be defined as a type of process through which a large rock is gradually broken down into smaller fragments by the action of water, wind, roots of plants, etc. Weathering is of two types:

  • Physical weathering/Mechanical weathering:
  • Chemical weathering.

When the process of weathering may be terminated, the activity of erosion may have occurred. This activity is also carried out by factors like water air, overgrazing of cattle, human activities like deforestation, etc. The main effect of soil erosion is to remove the topsoil which is extremely fertile in nature.

Therefore, erosion and weathering are the two parts of sedimentary rock formation that include the breakdown and carrying away of existing rock. Thus, the correct option for this question is D.

How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan ​

Answers

Answer:

18 molecules of CO_(2)

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

The information in neural transmission which always travels in one direction in the neuron first goes through the ____________.

Answers

Answer: Sensory neuron

The information in neural transmission which always travels in one direction in the neuron first goes through the sensory neuron

Explanation:

The sensory neuron transmits impulses from the sensory cell or receptor towards the central nervous system (spinal cord and brain). From there they are relayed to the intermediate neuron, before being transferred to the motor neuron that brings about a response.

See the chart below

Sensory neuron ----> Intermediate neuron ----> Motor neuron

Final answer:

In neural transmission, information first goes through the dendrite of a neuron, converting chemical signals into electrical impulses. These impulses then travel to the axon and finally, the axon terminals. The unidirectional flow of these signals ensure clear and constant transmission of messages.

Explanation:

The information in neural transmission that always travels in one direction in the neuron first goes through the dendrite. The dendrites are specialized to receive chemical signals from the synaptic cleft which are then converted into electrical signals.

From there, the electrical impulses (or action potentials) flow through the neuron, to the axon and finally to the axon terminals, where the signal is ready to be transmitted to the next neuron via neurotransmitters.

This unidirectional flow of information ensures that messages are transmitted in a clear and consistent manner throughout the neural network.

What is meant by the cell cycle or cell division cycle?

Answers

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication).The cell cycle consists of four distinct phases: G1 phase, S phase (synthesis), G2 phase (collectively known as interphase) and M phase (mitosis). 

G1 = growth and preparation of the chromosomes for replication; 
S = synthesis of DNA and duplication of the centrosome; 
G2 = preparation for mitosis or M phase 
M = mitosis and cytokinesis. 

Final answer:

The cell cycle is an ordered series of events involving cell growth and division that produces two daughter cells. It consists of interphase and the mitotic phase, where DNA replication and division occur. The cell cycle is crucial for cell growth, development, and reproduction.

Explanation:

The cell cycle is an ordered series of events involving cell growth and cell division that produces two new daughter cells. It has two major phases: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. The cell cycle is a crucial process for the growth, development, and reproduction of cells.
