g The first phase of the Calvin cycle is the (a)_____ phase. During this phase, a single CO2 molecule located in the (b)______ of the chloroplast gets fixed with (bonds with) a CO2-acceptor molecule called (c)_____ . This is a (d)_____ (number)-carbon molecule, which becomes an unstable 6-carbon molecule once it is carboxylated by CO2. This unstable molecule immediately splits into (e)______ (number) 3-carbon molecules called (f)_____ , which are the products of this phase of the Calvin cycle.
Answer:
a) Carbon fixation phase
b) stroma
c) Ribulose bisphosphate (RuBP)
d) 5-carbon molecule
e) two carbon molecules
f) glycerate-3-phosphate (GP)
Explanation:
In the Calvin cycle (also named C3 cycle or Calvin-Benson cycle), the CO2 is reduced in a cyclic process, where the first stable reaction product is 3-phosphoglyceric acid (3-PGA), a 3-C molecule, and the CO2 acceptor molecule is Ribulose bisphosphate (i.e., Ribulose 1, 5-diphosphate). The CO2 enters the chloroplast by passing through the stomata and diffusing into the stroma of the chloroplast, which is the site where sugar is synthesized. The Rubisco enzyme or RuBP carboxylase catalyzes the first step of the cycle (i.e., the attachment of CO2 to RuBP). The result of this reaction is an unstable 6C molecule, which breaks down into two 3C molecules named glycerate-3-phosphate (GP).
Which of the following best describes the formation of the bond shown in Figure 1 ?
А
An ionic bond is formed between a carbon atom of one amino acid and the nitrogen atom of the other amino acid,
B
An ionic bond is formed when the negative charge of an OH group is balanced by the positive charge of a hydrogen ion.
с
A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O
D
A covalent bond is formed that replaces the hydrogen bond between the OH group and the H atom,
A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O.
HOW PEPTIDE BOND FORMS:
Peptide bond is a bond that forms when two amino acids comes together. It involves the fusion of the amino group of one amino acid (NH2) and carboxyl group of another (COOH) with the release of water (H2O). Peptide bond is a type of covalent bond because it involves sharing of electrons between a carbon atom (C) and a nitrogen atom (N).Therefore, in the reaction shown in the image attached, a covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O.

Answer:
To withdraw ATP from food
Explanation:
Imagine two closely related, but separate, species of fish reproduce and the hybrids offspring have higher fitness than either of the parent species. Given enough time, the most likely outcome will be: Group of answer choices The two original species will eventually fuse into a third new species, and disappear. The two original species will remain, and a third new species will appear. Nothing: the two original species will remain, and the hybrids will eventually disappear.
Answer:
The two original species will eventually fuse into a third new species, and disappear.
Explanation:
According to Darwin's theory of evolution, species that are better adapted to their environment have greater chances of surviving long enough to reproduce and pass on these favourable characteristics to their offspring. This is known as 'survival of the fittest'.
The original species lack the resilience of the new hybrid species hence the two original species will eventually disappear and fuse into the third specie.

C. Ecological niche ` D. Fundamental niche
E. Realized niche F. Resource partitioning
1. When two species compete for exactly the same resources (oroccupy the same niche), one is likely to be moresuccessful.One species outcompetes the other and eventually the secondspecies is eliminated
2. Some species coexist in spite of apparent competition for the sameresources. Closer study reveals that they occupy slightly different niches; dividing up the resources by pursuing slightly different resources or securing resources in slightly different ways.
3. Five species of warblers coexist in spruce trees by feeding on insects in different regions of the tree and by using differing feeding behaviors to obtain the insects
4. Niche shift
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. Selection of these characteristics (or characters) reduces competition with individual in other partitions and leads to a divergence of features.6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
7. The resources a population uses in the absence of competitors or under ideal circumstances
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
9. The resources a population actually uses
Answer and Explanation:
A. Character displacement: This refers to the change of a trait or characteristic. Two species that share the same space must develop different characteristics in order to reduce competition and make better use of resources.
5. As a result of resource partitioning, certain characteristics may enable individuals to obtain resources in their partitions more successfully. The Selection of these characteristics (or characters) reduces competition with individuals in other partitions and leads to a divergence of features.
6. Two species of finches that live on two different islands have similar beaks, both suited for using the same food supply (seeds). On a third island, they coexist, but due to evolution, the beak of each bird species is different. This minimizes competition by enabling each finch to feed on seeds of a different size.
B. Competitive exclusion principle: The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.
1. When two species compete for exactly the same resources (or occupy the same niche), one is likely to be moresuccessful.One species outcompetes the other and eventually, the second species is eliminated
C. Ecological niche: The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species.
8. The sum total of the organismâs use of the biotic and abiotic resources in its environment
D. Fundamental niche: The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species.
7. The resources a population uses in the absence of competitors or under ideal circumstances
E. Realized niche: The realized niche refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species.
9. The resources a population actually uses
F. Resource partitioning: Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrates or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physic location allows both species to coexist more effectively.

1. Why are viruses considered nonliving but bacteria are considered living? Give two reasons. (1 point)
Answer:
-Viruses cannot replicate.
-Viruses do not need to consume energy to survive or regulate its own temperature.
Explanation:
<3
Viruses are not able to replicate or carry out any of the functions of living cells on their own. They rely on the machinery of the host cell in order to replicate and produce new viruses, and they are not able to carry out functions such as metabolism, growth, or reproduction on their own.
Why viruses are considered non-living?Viruses are much simpler in structure than bacteria and other living cells. They do not have a true cell structure or any of the characteristic cell organelles found in living cells, such as a nucleus, mitochondria, or endoplasmic reticulum. Instead, they are composed of a small piece of genetic material (either DNA or RNA) surrounded by a protein coat.Learn more about viruses, here:

Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.

The diagram shows water molecules as solid ice at 0°C and as a liquid at 25°C. Explain why the arrangement of water molecules is different in ice and water.
Answer:
In low temperatures, hydrogen bonds between water molecules become stable as a result of the movement of these molecules are slow in low temperature which leads to the crystalline form of water due to hydrogen bond. This crystalline form is ice.
on the other hand at a higher temperature water molecules found in liquid form due to the faster and rapid movement of water molecules as hydrogen bonds keep breaking and forming in this setting.

4. Mutualism
5. Parasitism
6. Mutualism.
7.Commensalism
Explanation:
Hermit crabs protect themselves from predators by living in shells discarded by snails and Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves relationship is commensalism because commensalism is a symbiotic relationship that take place between two organisms in which one benefits and the other is neither harmed or does not benefit. Hermit crabs benefit by receiving protection from snail shells and snail does not benefit and not harmed. Cattles eagret feed on insects on cattle hoolves, cattle is not harmed or does not benefit
Parasitism
2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees and The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host are parasitism relationship because parasitism is a relationship that exists between two organisms in which the other called the predator infect , harm or cause damage to the host organism. The above are parasitism relationship because they cause damage to their host.
Mutualism
The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia and On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites exhibit mutualism relationship because mutualism is a symbiotic relationship that exists between two organisms in which both benefits from the relationship. The Acasia and the ants receive protection from the relationship. The finches and tortoise benefited from their relationship.
