Explanation:
Selective cutting leaves forests that are just like old growth forests.
true
or
false
The statement that selective cutting leaves forests that are just like old-growth forests is false.
When selective cutting is implemented, it involves removing moderate to fully mature trees individually or in small groups. Although this technique is less damaging compared to other harvesting methods such as clear-cutting or strip-cutting, it still alters the forest's structure and can cause considerable ecological impact, especially in tropical forests. Old-growth forests have developed over centuries into complex ecosystems with a high degree of biodiversity and a unique genetic pool, which cannot be replicated simply through selective cutting and replanting.
Old-growth forests are known for their intricate web of life, serving as crucial habitats for many species. Once these ancient trees are cut down, they are lost forever; replanting trees does not restore the original old-growth forest due to the loss of biodiversity and the unique genetic composition that took hundreds of years to establish. Selective cutting, while a more sustainable approach compared to clear-cutting, does not leave forests resembling their original old-growth state.

Which pathogen depends on living cells to reproduce
Answer:
The correct answer is viruses.
Explanation:
A virus is the pathogenic non-living organisms which infect the host.
They are considered non-living as they do not have their own replication machinery and so depend on the host for their replication machinery, therefore, they are non-living without host organisms and need a host to survive.
Virus inject their genetic material in the host where it is integrated into the DNA of the host and the segment of the DNA of the virus gets replicated along with the DNA of the host which is then coated with the capsid of the virus,
Thus, the virus is the correct answer.

what is antibody and antigen?
Antigens are molecules proficient in motivating an immune response. Each antigen has different surface features, or epitopes, causing in specific responses. Antibodies (immunoglobins) are Y-shaped proteins produced by B cells of the immune system in reply to contact with antigens.
In fruit flies, the traits for a yellow body and white eyes are always inherited together. Which conclusion can be drawn from this phenomenon?
A. The genes for the traits are adjacent in the genome.
B. Both traits are dominant.
C. The species has only one allele for each trait.
D. The traits are controlled by one gene.
Answer: Option C. The species has only one allele for each trait is correct.
Any trait in an organism can be determined by a single gene containing two alleles one from each parent and one allele dominant over the other. A single trait is affected by a single locus. Only one single trait can be expressed by a single gene and a gene can never encode for more than one trait. The traits that are expressed are independent of the locus of the gene or position of the gene. Without knowing the genotype it cannot be predicted that both traits are dominant or not and it may be possible that either of the trait is recessive. Therefore it can be concluded that the species has only one allele for each trait which is expressed.
a single lunar cycle lasts a

4.year
The answer is; 3
A lunar cycle is the phases of the moon as it orbits, once, around the earth (which takes approximately 29.5 days). These phases can be viewed from the earth - new moon to full moon. The light from the sun that hits the moon reflects to the earth. Depending on the position of the moon, in its orbit, and with respect to a person at a particular position of the earth, the moon will be in a particular phase.

What is the literal meaning of the term "Binomial Nomenclature?" Give an example of when it is beneficial to use the scientific name of an organism.
Binomial nomenclature ("two-term naming system"), also called binominal nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, binominal name or a scientific name; more informally it is also called a Latin name.
The literal meaning of the term "Binomial Nomenclature" is the naming system that uses two words to identify a species.
What is the Binomial Nomenclature?Binomial Nomenclature is made up of two words. The first word represents the genus, and the second word represents the specific epithet. For example, Homo sapiens is the scientific name for humans, with "Homo" being the genus and "sapiens" being the specific epithet.
It is beneficial to use the scientific name of an organism when there is a need for precision and clarity in communication. Common names can vary depending on location, language, and culture, which can lead to confusion.
However, scientific names are universally recognized and accepted. Scientists, researchers, and academics use scientific names to avoid ambiguity when discussing a particular species. This allows for easier and more accurate communication of information, particularly in fields such as biology, zoology, and botany.

Viruses are accelular entities and do not possess cellular membranes in their structure. Thus, option A is correct.
What is virus?Virus are considered as a potent pathogenic organism for carrying infection in the body of the host. Viruses have the unique properties which demarks them from living and non-living creatures.
Virus can be considered non-living in the outer environment however they possess the property of life once they enter into the body of the host. Viruses have the ability to multiply in the body of the host by utilizing host DNA and proteins as machinery for replication.
Virus can have RNA or DNA as their genetic material and they can efficiently pass through the bacterial filters because of their small size.
Virus can cause severe infections in man, plants as well as in cattle. Common cold, HIV AIDS, hepatitis are some examples of virus in human.
Thus, virus can be considered as an infectious agents.

Landforms tend to weather and wear down over time. The Grand Tetons are an area of steep, rugged mountains that are thought to be about 9 million years old. What change would an observer most likely see if he could look at the mountains again after another 9 million years?
Answer:
Explanation:
Over time, steep hills are weathered. Weathering and erosion break down and remove rocks and soil such that the mountains tops become more rounded and the rocks and soil deposit on the hillsides, making them less steep.
After another 9 million year of erosion and deposition, an observer could expect the mountains to be less steep and more rounded.

C. Within the mitochondria’s inner membrane.
D. Within the mitochondria’s matrix.
Make sure your answer is correct! Plz
Within the mitochondrion’s inner membrane
The right answer is C. Within the mitochondria’s inner membrane.
The mitochondrion is limited by two membranes of very different properties:
* the outer membrane contains a transmembrane protein, porin, which allows the passage of ions and water-soluble metabolites of molar mass <10.000 Da.
* The inner membrane is very rich in proteins and almost impermeable to ions and water-soluble metabolites.
The respiratory chain or electron transport chain is located in the inner membrane of mitochondria. Each mitochondrion contains thousands of copies of the electron transport chain.
