Answers

Answer 1

Answer:

1. An evolutionary trait that is homologous within groups of organisms (see homology) that are all descended from a common ancestor

2. Derived traits are those that just appeared (by mutation) in the most recent ancestor -- the one that gave rise to a newly formed branch.

3. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor.

4. It helps us to form a cognitive framework of understanding complexity.

5 Because it is a learned trait. For some domains, like Bacteria and Archeabacteria, DNA is transferrable

6. A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.

7 Polyhedral, Helical, Complex, Spherical

8. Sometimes referred to as temperate or non-virulent infection, does not kill the host cell, instead using it as a refuge.

Woodpeckers and squirrels fight for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna fight for the same antelope and gazelle prey. Which of the following statements about these relationships is accurate?

A. These are examples of competition because the organisms are fighting for resources.

B. These are examples of predation because the organisms are trying to take each other’s food and homes.

C. These are examples of predation because lions and cheetahs eat woodpeckers and squirrels.

D.These are examples of competition because no organisms are helped or harmed.

Answers

Answer:

a

Explanation:

both of the cases the organisms are fighting for a resource

A. These are examples of competition because the organisms are fighting for resources.

How Competition and predation are two different types of relationships ?

Competition and predation are two different types of relationships that can exist between different organisms in an ecosystem. Competition occurs when two or more organisms are fighting for the same resources, such as food, water, or shelter.

This can occur within or between different species. In the example given in the question, woodpeckers and squirrels compete for nesting rights in the same holes and spaces in trees, while lions and cheetahs compete for the same antelope and gazelle prey.

On the other hand, predation occurs when one organism (the predator) hunts, kills, and consumes another organism (the prey). This type of relationship is often seen between carnivores and herbivores, or between animals and insects. In the example given in the question, lions and cheetahs are predators that hunt and consume antelope and gazelle prey.

It is important to note that in both competition and predation, one organism may benefit while the other is harmed.

For example, in predation, the predator benefits by getting food while the prey is harmed by losing its life. In competition, one organism may gain access to the resources while the other loses out, which can affect their ability to survive and reproduce.

Answer: 1. Its Structure. The ATP molecule is composed of three components. ... These phosphates are the key to the activity of ATP. ATP consists of a base, in this case adenine (red), a ribose (magenta) and a phosphate chain (blue). 2. Adenosine 5'-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. 3. All living things use ATP. In addition to being used as an energy source, it is also used in signal transduction pathways for cell communication and is incorporated into deoxyribonucleic acid (DNA) during DNA synthesis.  4. All living things use ATP. In addition to being used as an energy source, it is also used in signal transduction pathways for cell communication and is incorporated into deoxyribonucleic acid (DNA) during DNA synthesis. 5. Adenosine Triphosphate is a nucleotide molecule with three phosphate groups joined in a row. ... When the third phosphate group is broken away from the ATP molecule, the stored energy is released. This, smaller amount of energy can then be safely used in other cellular reactions of life processes. ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). The negative charges on the phosphate group naturally repel each other, requiring energy to bond them together and releasing energy when these bonds are broken. 5. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds. When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). 6. When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). ...

Which of these islands would likely have the most species diversity.
A small island in the middle of the ocean
O A large island near the mainland

Answers

Answer:

A large island near the mainland

Explanation:

A large island has a greater number of species, a greater interaction between them and a greater number of natural elements. All of this is capable of promoting biological specialization on a large scale, allowing new species to emerge more quickly than on a small island. Although a small island may also have great biodiversity, that island has fewer factors that promote the creation of new species, in addition to having fewer species interacting and creating new species.

Question:
Using a specific example, discuss the importance of electrons in the transfer of energy in living systems.​

Answers

Answer: The transfer of energy in the form of electrons allows the cell to transfer and use energy in an incremental fashion. The principle electron carriers are NAD+ and NADH because they can be easily oxidized and reduced, respectively.

Explanation:

Electrons are very significant in the steps of energy transfer in the living body cells.

When the electrons are displaced from the molecule it gets oxidized which results in a reduction in the potential energy.

Electrons transfer is very important because most of the power is stored in the atoms in the form of electrons that are required for cell functioning.

The chief electron transporters are NADH and NAD⁺ they reduce and oxidizes the compounds.

NADis oxidized and NADH is the reduced form of the molecules.

The living structures cannot save a large amount of energy and hence they collect them in the form of ATP and electrons.

It is believed that understanding heat stress in birds by paying detail attention to the sources of heat generation in a poultry house can help manage the heat stress situation in this region. This text reviews the internal climatic conditions of the poultry houses, how the birds respond to them, and their implications for heat management in poultry production. Thus, it provides pertinent information for guidance on parameters for open poultry houses architectural design that ensures optimum climatic conditions that will alleviate heat stress problem in poultry production in hot and humid climate.
