what is the organism that is harmed in the parasitism called ?
A: Competitor
B: Host
C: Parasite
D: Prey

The correct answer is nucleoplasm.

The nucleus of the majority of the cells comprises a substance, which suspends compositions inside the nuclear membrane. Similarly, to the cytoplasm, the nucleus comprises of nucleoplasm, also called karyoplasm.

The nucleoplasm is a kind of protoplasm, which comprises the majority of water, dissolved ions, and a mixture of different molecules. It is entirely enveloped inside the nuclear envelope or nuclear membrane. It is a sticky liquid, highly gelatinous, which supports the nucleoli and chromosomes.

The main activity of the nucleoplasm is to function as a suspension material for the organelles within the nucleus. It also assists in sustaining the composition and shape of the nucleus and plays an essential function in the transportation of substances, which are important to cell function and metabolism.

The given is an example of an experiment because it does not ask for a testable question. Thus, the correct option will be B.

An experiment can be defined as a procedure which is being carried out to support or to refute a hypothesis, or for determining the efficacy or likelihood of something which is previously untried. Experiments have been found to provide insight into the cause-and-effect type of relationship by demonstrating what actually the outcome occurs when a particular factor is manipulated in an experimental study.

d. An investigation because there is a control group

Answer:

No change in temperatures between seasons or B

Explanation:

A chromosome unfolding enhances transportation by making DNA segments accessible for transcription. Hence, the correct option is option 1.

When a chromosome unfolds itself, the process enhances transportation by allowing specific segments of DNA to become accessible for transcription. The nucleosomes, which are complex structures of DNA and protein, can slide down the DNA to open up chromosomal regions. This opening of the chromatin structure is vital for the transcriptional machinery, such as RNA polymerase, to initiate the transcription of DNA into RNA. Hence, accessibility is significantly increased as the unfolded DNA provides an opportunity for transcription factors and RNA polymerase to bind to the exposed DNA sequences and carry out the transcription process.

Accessible, transcriptionally active regions of DNA are known as euchromatin, while DNA packaged so that it is inaccessible to regulatory protein binding is known as heterochromatin. Essentially, chromatin dynamics—such as the opening and closing of nucleosomes—allow DNA to be transcribed, move histones to open or close a chromosomal region, and are temporary changes that contribute to gene regulation.

Yes, genetically modified organisms should and are available for human consumption, and they are fully tested before introducing to humans.

A genetically modified organism (GMO) is a living organism whose DNA has been altered using genetic engineering techniques. Humans have utilized breeding strategies to modify creatures for thousands of years. Over millennia, corn, livestock, and even dogs have been selectively selected to have particular desired features.

These organisms are safe to eat because they are fully tested before introducing to people.  These organisms contain more nutrients than normal animals and can prepare in vitro conditions.

Therefore, yes, genetically modified organisms should be available for human consumption.

The blue jay, robin, cardinal, and canary, being songbirds, are closely related and would be clustered together in a cladogram. The pelican, however, belongs to a different clade, Aequorlitornithes, and would be positioned separately from the others.

Ordering Birds in a Cladogram

To understand the order in which the birds blue jay, robin, cardinal, canary, and pelican should be placed in a cladogram, we need to consider their evolutionary relationships. The blue jay, robin, and cardinal are part of the Passeriformes order, which is part of the Inopinaves clade—a larger group that also includes hawks, owls, woodpeckers, and songbirds. The canary is also a songbird and therefore falls within the same clade. Pelicans are part of the Pelicaniformes order and belong to a different clade called Aequorlitornithes, which includes diving birds and wading birds.

In a cladogram, the birds that share the most recent common ancestor are grouped more closely. Since blue jays, robins, cardinals, and canaries are all considered songbirds, they are closely related and should be grouped together in the cladogram. The pelican, on the other hand, would branch off earlier as it is part of a different clade.

Without specific genetic information, placing these birds in an exact order is challenging, but in general, canaries, cardinals, robins, and blue jays would appear closer together while the pelican would be positioned apart from them in the cladogram.

In the period when the lush ancient forests exited on Earth, the ones that provided the material for the formation of the coal that we use nowadays, Australia did not provide the right conditions for the existence of these forests.

The problem was that Australia was located very close to the South Pole in that period. Because of its location, Australia was colder and drier than most of the landmass on the Earth. By having less precipitation, and colder climate, Australia was not suitable for the tropical rainforests of that period, thus it did not had the material from which the coal formed latter on in the geological time scale.
