The synthesis of complex molecules _______ energy, whereas their degradation _______ energy. this synthesis occurs with _______ in entropy.

Answers

Answer 1
Answer: The correct terms to fill in the blanks would be requires, releases and decrease, respectively. The synthesis of complex molecules requires energy, whereas their degradation releases energy. This synthesis occurs with a decrease in entropy. The synthesis of the complex molecules is an endothermic process where it requires supply of energy for the process to occur while the degradation is exothermic where it releases excess energy as the process proceeds. Synthesis of these molecules is accompanied by a decrease in entropy since the disorder in the system is lowered due to the bonding of two smaller molecules into one larger molecule.

What are the underlying principles of conservation biology? I) Biodiversity is necessary for all life on earth, II) Humans should not disrupt vital ecological processes, III) The best way to preserve earth's biodiversity is to protect intact ecosystems I only II only III only II and III only "I, II, and III"

Answers

Answer: II) Humans should not disrupt vital ecological processes, III) The best way to preserve earth's biodiversity is to protect intact.

Explanation:

Principles of conservation biology deals with the management of the earth's biodiversity. Their aim is to protect the species from extinction. Saving the habitat and ecosystem of the species. Also aims at protecting and managing the natural resources. These principles aims at protecting the biodiversity at species, genetic and ecosystem levels. These principles emphasize over protecting the natural biodiversity against human interventions and interruptions.

What is the difference between a gene and an allele? 1. A gene is a segment of DNA that codes for a protein or RNA; alleles are alternate forms of a gene.
2. A gene is a segment of DNA that codes for a protein or RNA; the term allele refers to all of the DNA in a cell or organism.
3. An allele is a segment of DNA that codes for a gene; genes are alternate forms of an allele.
4. An allele is a segment of DNA that codes for a protein or RNA; genes are alternate forms of an allele.

Answers

Answer:

1. A gene is a segment of DNA that codes for a protein or RNA; alleles are alternate forms of a gene.

Explanation:

DNA is the genetic material and stores genetic information. A stretch of DNA that codes for a specific protein is called a gene. Transcription of a gene forms mRNA which in turn is translated into a protein. Alleles are the alternative forms of a gene. A gene may have two or more alleles. However, diploid organisms can have two alleles for a gene which in turn are present on a particular locus on homologous chromosomes. For instance, I^A, i and I^B are the alleles for the ABO blood type in humans.

Two organs difficult to repair using stem cells

Answers

Answer: Apical meristem and the lateral. The heart, brain, bone marrow and the Lungs in adults are difficult to repair using stem cells.


Explanation:

There are two kinds of stem cells: embryonic stem cells and adult stem cells. Adults also have stem cells in the heart, brain, bone marrow, lungs, and other organs. They are our built-in replacement tools, restoring cells infected by infection, trauma and everyday erosion, and cut. Adult stem cells are extremely difficult for specialists to operate because they are extra challenging to derive and culture than their immature complements.

The lateral and apical meristem.

Reptiles, such as snakes, become extremely inactive during the winter months. They become active again, hunting for food, when the weather becomes warmer. Which of these would BEST explain why this is true? A) Reptiles are warm-blooded. B) Reptiles are cold-blooded. C) Reptiles have learned to hunt in warm temperatures. D) Reptiles make the choice to become inactive in cold temperatures.

Answers

its b  reptiles are cold blooded  


The answer is B, even though it is not technically correct.  The term "cold-blooded" is a misnomer as it applies to reptiles.  Reptiles are poikilothermic, which means they have to absorb heat from the environment in order to maintain metabolic functions.  Without enough heat, they become lethargic, and are unable to digest their food.
