6. Many plants of the tropical rain forest are successful houseplants. What characteristics make
these plants successful indoors?
PLEASE HELP
Answers
Tropical rainforest plants are popular houseplants because they possess several characteristics that make them successful indoors. First, they are usually low-maintenance, requiring minimal pruning and watering.
They also typically do not require direct sunlight, so they can thrive in indirect light, common in most indoor environments. Furthermore, they are typically slow growing plants, so they do not need to be repotted often and will not quickly outgrow their pot.
Finally, many tropical rainforest plants have attractive foliage and colorful flowers, making them aesthetically pleasing additions to the home. All of these characteristics make tropical rainforest plants ideal for indoor use.

Explanation:
Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.

Answers
The amino acids would be most similar to the ingredients used in the recipe.
When the mRNA moves out of the nucleus, it then gives the instructions (the genetic sequence) to someone else, which is tRNA. During translation, the tRNA and mRNA complex reads the genetic sequence and then binds required amino acids, sequentially. Thus, the combined amino acid chain forms the desired protein.

if a pair of homologous chromosomes fails to separate during meiosis i, select the choice that shows the chromosome number of the four resulting gametes with respect to the normal haploid number (n)?
Answers
Option (A) n + 1; n + 1; n - 1; n - 1 will be the chromosome number of the four resulting gametes with respect to the normal haploid number (n).
During meiotic anaphase-I, homologous chromosomes are separated. The descendant cells' chromosomal count is decreased from 2n to "n" as a result of this event. One daughter cell of meiosis-I (n+1) would have both homologous chromosomes of a pair if they do not separate during anaphase-I, while the other daughter cell would be devoid of that chromosome (n-1).
This chromosome count would remain the same after meiosis II. As a result, two gametes will each have one extra chromosome (n+1), as opposed to two gametes having one chromosome missing (n-1).

What would be the consequence of a chromosome losing its centromere?
The chromosome would not be drawn into a newly formed nucleus and would be lost.
Answers
Losing a centromere on a chromosome can have significant consequences for the cell and organism.
The centromere is a critical region on a chromosome that acts as the primary attachment point for microtubules from the spindle apparatus during cell division. Microtubules from opposite poles of the cell attach to the centromere, and the pulling tension generated by these microtubules helps to separate the chromosomes into the two newly formed nuclei.
If a chromosome loses its centromere, it would no longer have a site for the spindle microtubules to attach to, and as a result, it would not be drawn into one of the newly formed nuclei. Instead, it would likely be lost or degraded.
This can result in a loss of genetic information, leading to abnormal development and potential diseases such as cancer. Additionally, if the lost chromosome carries critical genes involved in regulation or cell division, this could lead to cell death or abnormal growth.

alveoli walls are compsed of two types of cells the cells that form the respiratry membrane are ___ cells
Answers
Answer:
The cells that form the respiratory membrane in the walls of alveoli are called "pneumocytes" or "alveolar epithelial cells".
The cells that form the respiratory membrane in the alveoli walls are called Type I alveolar cells, or simply Type I cells.
These cells are extremely thin and flat, allowing for efficient gas exchange between the lungs and the bloodstream. Type I cells make up the majority of the alveolar surface area and are responsible for the bulk of gas exchange in the lungs.
They are in direct contact with the capillaries, which allows oxygen to diffuse across the respiratory membrane and into the bloodstream while carbon dioxide diffuses in the opposite direction.
Type II alveolar cells, on the other hand, secrete surfactant, a substance that helps to reduce the surface tension of the alveolar fluid and prevent the collapse of the alveoli during exhalation.
While Type II cells do not directly participate in gas exchange, their function is crucial to maintaining the structural integrity of the alveoli and preventing respiratory distress syndrome in premature infants.

Most eukaryotic mRNAs are shorter than the genes that encode them. The reason for this is __________.
Answers
"most eukaryotic mRNAs are shorter than the genes that encode them" because the non-coding regions of the gene are removed before the mRNA leaves the nucleus. These non-coding regions of the gene are called introns while the coding regions are called exons. Hence, the process of removing introns and joining exons together is called splicing.
Pre-mRNA is the primary transcript synthesized in eukaryotic cells, which is initially processed in the nucleus to mature mRNA before it is transported out to the cytoplasm for translation. The pre-mRNA usually contains both introns and exons. Introns are non-coding regions, while exons are coding regions that will ultimately form the amino acid sequence of the protein that the gene encodes.
Introns are generally longer than exons. Therefore, if they are retained in the mRNA, it will increase the size of the mature mRNA, which will be impractical for the cell to transport to the cytoplasm. Hence, the non-coding regions of the gene are removed before the mRNA leaves the nucleus. This process is called splicing, which removes the introns and joins the exons together. After splicing, the mature mRNA is produced, which is shorter than the gene that encodes it.

Animal body systems often coordinate their actions to carry out specific functions for the whole animal. Which of these correctly describes the interaction of two biological systems for a specific purpose in the human body?
Answers
Answer: I believe c is what you're looking for, D is also a viable option, but C is more likely.
Explanation:
The integumentary and immune system correctly describes the interaction
of two biological systems for a specific purpose in the human body.
The integumentary system which comprises of the skin, hair and nails help in
the protection and prevention of foreign substances from entering into the
body.
In situations where there is a cut or pathogenic microorganisms being
present in the body then the immune system acts by production of
antibodies which fight them.
The two systems work hand in hand to protect the body from foreign
compounds or organisms which may cause illness and death.

the lipopolysaccharide molecule is an important component of the cell membranes of which organisms?
Answers
The lipopolysaccharide (LPS) molecule is an important component of the cell membranes of gram-negative bacteria.
Gram-negative bacteria are a diverse group of bacteria that are characterized by their cell walls, which consist of a thin layer of peptidoglycan surrounded by a thicker outer membrane. The outer membrane contains a variety of lipids and proteins, including the LPS molecule.
LPS is a large, complex molecule that is composed of three parts: a lipid, a polysaccharide, and a protein. The lipid component, known as lipid A, is responsible for the toxic effects of LPS, while the polysaccharide and protein components are involved in the recognition and specificity of LPS by the host.
The presence of LPS in the cell membrane of gram-negative bacteria makes them highly resistant to certain types of antibiotics and other antimicrobial agents. LPS also plays a role in the pathogenesis of many gram-negative bacterial infections, as it triggers an immune response that contributes to the symptoms of the infection. For these reasons, LPS is an important target for the development of new antibiotics and other treatments for gram-negative bacterial infections.
