why does oxygen and carbon dioxide travel within the seed and the egg.
Answer:
To break energy or food found inside the egg or seed
Explanation:
The oxygen enters the seed coat as the seed coat softens and it combines with the stored energy of the seed. During early stage, the oxygen is required but the carbon dioxide increases later as
Oxygen and carbon dioxide travels within the seed and egg to :
Break the energy or food inside the egg / seedHow the Oxygen travelsAs the oxygen enters the seed it is absorbed by the seed coating. the seed coating becomes wet and softens due to the oxygen absorption.
The soft seed coating then combines with the energy present in the seed, during this combination/early stage between the seed coating and the energy stored in the seed the Oxygen is most effective.

What are some featured species in the deep sea?
What is so fascinating about our deep blue sea is the fact that there could be so many more species than the ones we know about. Our oceans are so vast and deep anything could really be down there. I don't exactly know what you mean by this question but I can give you some deep-sea creatures that have been discovered, although some sound equivalent to science fiction, they are in fact real.
- Giant Isopod: they are a species of aquatic crustacean. Their appearance is that of a much larger bug, similar to those "rolly polly" bugs. They reside in the deep sea scuttling along the seabed and ultimately harmless to humans.
- Vampire Squid: This creature looks similar to many other squids such as their squid-like bodies and tentacles, however, what makes this squid unique is its black webbed skin (resembling a vampire cape) and its red eyes. The vampire squid's body is covered in photophores that produce light to attract prey.
- Frilled Shark: This is an odd-looking shark that lurks in the deep sea. It looks almost pre-historic and can grow up to a length of 7ft with a typical shark fin further down its back as well as the well-known rows of sharp teeth. Its gills appear to be frilled hence its name.
- Anglerfish: These deep-sea creatures are pretty commonly known. They are frightening-looking fish with long thin teeth lining their mouth and the notable luminescent fin ray that it uses to lure other fish to eat.
So these were just some notable deep-sea creatures that I have heard of and I wrote some information about them. Hope this helped :)

Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Osmosis is one of the most important ways that plants and animals achieve homeostasis.
The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. Therefore, the water flows into the roots. The guard cells of the plants are also affected by osmosis.

Which of the following adjustments might the bacterium make to maintain the same level of membrane fluidity?
An adjustment that bacteria might make to maintain the same level of membrane fluidity is to produce lipids with shorter lengths and more double bonds.
The fluidity of the cell membrane is the property of the cell membrane to adapt to shape and movement under different conditions. The fluidity of a membrane is usually affected by the amount of saturated fatty acids that make the membrane less fluid and unsaturated fatty acids that make it more fluid. In addition, fluidity also depends on temperature, where high temperatures make it more liquid and low temperatures make it denser.
To maintain the fluidity membrane, bacteria will adjust the lipid composition of the membrane by changing the fatty acid phospholipid bilayer. Bacteria will produce lipids with shorter hydrocarbon tails and have more double bonds. By doing so, it maintains the fluidity and permeability of the membrane.

is asthma is cased by virus
Answer:
Explanation:
Asthma is characterized by spasmotic contraction of the smooth muscle of the airways, by increased production of an abnormally viscous mucus by bronchial mucous glands, and, in severe attacks, by airway obstruction from mucus that has accumulated in the bronchial tree. This results in a greater or lesser degree of difficulty in breathing. One approach to classifying asthma differentiates cases that occur with an identifiable antigen, in which antigens affect tissue cells sensitized by a specific antibody, and cases that occur without an identifiable antigen or specific antibody. The former condition is known as extrinsic asthma and the latter as intrinsic asthma. Extrinsic asthma commonly manifests first in childhood because the subject inherits an atopic characteristic: the serum contains specific antigens to pollens, mold spores, animal proteins of different kinds, and substances from a variety of insects, particularly cockroaches and mites that occur in house dust. Exacerbation of extrinsic asthma is precipitated by contact with any of the substances to which sensitization has occurred; airway obstruction is often worse in the early hours of the morning. The other form of asthma, intrinsic, may develop at any age, and there may be no evidence of specific antigens. Persons with intrinsic asthma experience attacks of airway obstruction unrelated to seasonal changes, although it seems likely that the airway obstruction may be triggered by infections, which are assumed to be viral in many cases. Asthma attacks may be precipitated by food. For example, in small children, sensitivity to milk may stimulate an attack, and, in some adults, sensitivity to sulfite compounds found in some foods and wine may stimulate an attack. A subgroup of asthmatics are so sensitive to aspirin (acetylsalicylic acid) that ingestion of this chemical may lead to a life-threatening attack.
Answer:
No, not necessarily
Explanation:
Asthma isn't necessarily caused by a virus or a pathogen. It can be genetic or environmental, meaning that it can be passed down through family members, or it can result from an environmental factor, such as allergies or poor air quality.

The organism described that can cause illness and death in humans, reproduces asexually, and is among the simplest of living things, is a bacterium.
Bacteria are single-celled microorganisms that can be found in various environments, including soil. They are characterized by their simplicity of structure and lack of a nucleus or membrane-bound organelles.
Certain species of bacteria are pathogenic and have the ability to cause diseases in humans. Examples include bacteria like Escherichia coli (E. coli), Salmonella, and Staphylococcus aureus.
These bacteria can enter the human body through various means, such as contaminated food or water, and can cause a range of illnesses, from mild to severe, and even life-threatening conditions.
Bacteria have the ability to reproduce asexually through a process called binary fission. In this process, a single bacterium divides into two identical daughter cells, allowing for rapid multiplication of the population.
It is important to note that while bacteria can be harmful, many bacteria are beneficial or have neutral effects on humans and play crucial roles in various ecological processes and human health.

describe how the structure of an antibody is related to its function in your answer you must clearly link structure and function
Answer:
an antibody is a y-shaped structure which consists of four polypeptides, two heavy chains, and two light chains. this structure allows antibody molecules to carry out their dual functions: antigen binding and biological activity mediation
The function of antibodies, also known as immunoglobulins, is intricately linked to their unique structure.
These Y-shaped proteins consist of two heavy chains and two light chains. At the tips of the Y-shape, variable regions contain antigen-binding sites that enable antibodies to recognize and attach to specific antigens.
This structural specificity empowers antibodies to neutralize foreign substances, like pathogens or toxins, either by marking them for destruction or blocking their interactions with host cells.
Moreover, the flexible axis region of antibodies allows for optimal binding and adaptability.
The tight relationship between structure and function is essential for antibodies' role in defending against infections and contributing to immune responses.

in order for a mutation to be passed down, which cells in the parent would have to be mutated? why?
For a mutation to be heritable, it must arise in the germ line cells of the parent.
In order for a mutation to be passed down from parent to offspring, the mutation must occur in the parent's germ cells, specifically in the cells that give rise to sperm or eggs. These cells are known as the germ line cells.
The reason is that only mutations that occur in the germ line cells can be inherited by future generations. When an individual with a mutation in their germ line cells produces gametes (sperm or eggs), the genetic information contained within those gametes carries the mutation. If the mutated gamete successfully combines with another gamete during fertilization, the resulting offspring will inherit the mutation.
On the other hand, mutations that occur in somatic cells, which make up the body of an individual, cannot be passed down to offspring. Somatic mutations affect only the individual in which they occur and are not transmitted to future generations during reproduction.

HOMOLOGOUS CHROMOSOMES SEPERATE FROM EACH OTHER WHAT STAGE
Answer:
Homologous chromosomes separate from each other during anaphase I of meiosis.
Explanation:
Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.
During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.
In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.
