The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

Amylase, albumin, hemoglobin, keratin, and collagen are all option(c) i.e, proteins.

An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds. All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.

The three basic classes of proteins—globular, fibrous, and membrane—that correspond to typical tertiary structures can be arbitrarily grouped into three groups. Plant-based foods (fruits, vegetables, grains, nuts, and seeds) frequently lack one or more essential amino acids, but animal-based foods (meat, chicken, fish, eggs, and dairy products) are frequently good sources of complete protein.

The body uses protein for a variety of purposes. It promotes metabolic reactions, supports tissue growth and repair, and synchronizes biological processes. Proteins give your body a structural foundation while also ensuring optimal pH and fluid balance.

Explanation:

Answer:

You can use the quantitative Reverse Transcription Polymerase Chain Reaction PCR (RT-qPCR) method in order to analyze the Oct4 mRNA level.  

Explanation:  

RT-PCR is the gold standard technique to analyze the expression levels of one particular messenger RNA (mRNA) molecule. In this technique, the total RNA is firstly extracted and transcribed into complementary DNA (cDNA). Subsequently, the gene sequence of interest is then amplified in a standard PCR technique that uses as control one or more genes in order to measure the relative expression levels of the target mRNA, in this case, for example, the Oct4 mRNA.

Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.

Explanation:

Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:

       1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.

       2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).

       3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.

Answer:

A hypothesis is a kind of guess or proposition regarding a situation. It can be called a kind of intelligent guess or prediction, and it needs to be proved using different methods. Formulating a hypothesis is an important step in experimental design, for it helps to predict things that might take place in the course of research. -or- What this statement means is that a hypothesis is a guess that a researcher in academia or other fields make and then follows an extensive research to either prove or disqualify the developed hypothesis as true or false. In contrary, a prediction is just but a guess that an individual makes without backing it with the necessary research in hope that it will happen.

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.  

2. Some species coexist in spite of apparent competition for the same resources. A 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

Option A. Their numbers and diversity will be drastically reduced

If carbon dioxide levels continue to rise and coral reefs disintegrate by the end of the century, the most likely effect on marine organisms that rely on these reefs for food and shelter would be a drastic reduction in their numbers and diversity (option a). Coral reefs serve as crucial habitats and nurseries for a wide range of marine organisms, including fish, invertebrates, and other species.

The disintegration of coral reefs would result in the loss of their structural complexity, which provides shelter, protection, and food sources for many organisms. Without the reefs, marine organisms would lose their primary habitats and face significant challenges in finding suitable alternatives. They may be forced to disperse over greater distances in search of food and shelter, which could result in increased predation risk, competition for limited resources, and reduced reproductive success.

Additionally, the decline of coral reefs would lead to a decline in available food sources, as the reefs support a diverse ecosystem with complex food webs. Organisms that rely directly or indirectly on the reefs for sustenance would face food scarcity and potential population declines.

Overall, the loss of coral reefs due to rising carbon dioxide levels would have a profound and negative impact on marine organisms, leading to reduced numbers and diversity, increased competition for resources, and potential disruptions to reproductive patterns. Therefore the correct option is A

The secretory pathway shows the flow of vesicles from the Endoplasmic reticulum to the Golgi and from the Golgi to the ER. This bidirectional transport is necessary as the proteins which are functional to sent to their destination whereas the proteins which are not functional are sent back to the ER for repair.

The secretory pathway includes the transportation of the completely formed functional proteins from the ER to the golgi and from golgi to their destination i.e., cell membrane. This transportation of proteins takes place in the form of vesicles which carry cargo and, are sent to destinations within or outside the cell.

Vesicular transport is a major cellular activity which is responsible for the molecular traffic between a variety of membrane-enclosed compartments i.e., golgi apparatus and the ER. The selectivity of such transport and the bi-directional transport of vesicles is a key to maintaining the functional organization of the cell.

Answer:

The benefits of genetic diversity include:

Explanation:

Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.

Several alleles within a population's gene pools leads to higher diversity. These may become beneficial,  as the environment of the organism changes.  

Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.
