A. The atmospheric conditions that cause eclipses are only found at certain
locations and times of year.
B. The Moon's orbit is tilted relative to the plane of the Earth's orbit. About every
six months, the Sun, Moon and Earth are aligned enough for a solar and a lunar
eclipse to occur.
C. The Earth and Moon orbit the Sun in opposite directions. When the Moon's
orbit crosses the Earth's orbit, a lunar or solar eclipse will occur.
D. A lunar or a solar eclipse occurs every time the Moon orbits the Earth. The Moon
orbits the Earth four times a year.

Why are bryophytes classified into three divisions
Explanation:
Bryophytes are an informal group consisting of three divisions of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species.

What is the most important part in the respiratory system?
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.

Where in the plant are the hormones auxins produced? (Select all that apply.)
A. stems
B. roots
C. chloroplasts
D. seeds
E. leaves
F. fruits
Answer:
Stems and root
Explanation:
Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.
In stems, roots, leaves and fruits, hormones auxins are produced. Therefore, the correct options are A,B,E and F.
Plants' apical meristems are where auxins are predominantly made, and they are then carried by the plant's vascular system. Although there are synthetic auxins available for agricultural use, indole-3-acetic acid (IAA) is the predominant naturally occurring auxin in plants. Auxins are crucial hormones for plant growth and development, to sum up. They control a variety of tropic responses as well as cell elongation, apical dominance, root growth, phototropism, fruit development, and leaf abscission. Gaining knowledge of auxin regulation and function can help us better understand plant biology.
Therefore, the correct options are A,B,E and F.

PLS HELP The diagram below shows the relationship between respiration and photosynthesis.
How is combustion similar to cellular respiration?
Answer/Explanation:
In Cellular respiration, organisms use oxygen to break down down to food molecules in order to produce energy that is needed for body function.
Combustion, which is also known as burning, also involves the use of oxygen in the break down of chemical bonds to produce energy.
Both processes give off carbon dioxide in the process along with the energy they release.
Therefore, both processes seem very much alike.
Why does DMD affect mostly boys? Describe the type of inheritance pattern that DMD follows
Answer:
Inheritance in DMD
DMD is inherited in an X-linked pattern because the gene that can carry a DMD-causing mutation is on the X chromosome. Every boy inherits an X chromosome from his mother and a Y chromosome from his father, which is what makes him male. Girls get two X chromosomes, one from each parent.

In what way are thermal pollution and eutrophication similar in their impacts on aquatic ecosystems?
A) Both processes are caused by sewage effluent.
B) Both processes occur often in the spring and rarely in the winter.
C) Both processes increase the nutrients that are available in the freshwater ecosystem.
D) Both processes can lead to lowered dissolved oxygen and reduced biodiversity in lakes and rivers.
Answer:
“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.

Describe the ways that membrane proteins associate with the lipid bilayer, and discuss the functions of membrane proteins.
Answer:
Lipids are arranged in the form of a bilayer, while proteins are arranged in an irregular and asymmetric way between them. These components confer a certain degree of mobility to the membrane, giving rise to the pattern known as fluid mosaic. Membrane proteins, as will be seen later, can be peripheral or partially or totally integrated into the membrane, being generally globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients and the study of its structure is a priority.
Explanation:
The lipid bilayer is a fluid and dynamic structure. This dynamism of the bilayer is known as the fluid mosaic model, in which all the molecules that are part of the bilayer are actively involved, whether they are phospholipids, glycolipids, sterols and proteins, among others. Membrane proteins are located according to the structure of their amino acids, specifically their hydrophilic or hydrophobic properties. They are the main communication tools between the inside and outside of the cell, thanks to them the exchange of molecules such as nutrients or waste products, as well as receiving external signals. Peripheral proteins are attached to the membrane by van der Waals forces, hydrogen or ionic bonds. Generally, they have a net positive charge, the presence of negatively charged lipids in the membrane being necessary to give rise to an electrostatic-type anchoring. Integral (intrinsic) proteins are bound to the lipid bilayer in a very tight way, through covalent bonds and are subdivided into three categories: One- or multi-step transmembrane protein (in alpha helix). They are glycosylated at the extracellular end. They are generally receivers. Protein bound to one or more fatty acids (in the inner sheet). An example of this category is protein G. Protein bound to a lipid of the bilayer (phosphatidyl-inositol) by means of an oligosaccharide (in the outer sheet). As an example we have the neuronal adhesion molecules.

You should be familiar with the drugstore antibiotic ointment Neosporin (Triple antibiotic ointment), which is often thought of as innocuous. Based on your knowledge of antibiotics from Chapter 12 describe the mode of actions of the three antibiotics found in Neosporin (neomycin, polymyxin, and bacitracin), research their side effects, and postulate on why these three antibiotics were chosen.
Answer: Antibiotics are chemicals which, in low concentrations, can selectively kill or inhibit the growth of most pathogenic bacteria and are not harmful to humans.
Explanation:
Neosporin is a type of antibiotics which is used for the treatment or prevention of mild superficial infections. It consists of three active component, hence the name Triple antibiotic ointment. These active components, their mode of action and side effects include:
--> NEOMYCIN : This is one of the active components of Neosporin which inhibits the protein synthesis of an invading pathogenic bacteria through irreversible binding to the 30 S ribosomal subunit of susceptible bacteria. Their MODE OF ACTION is bactericidal meaning that the effect it has on the protein synthesis inhibits it's growth leading to the death of the bacteria.
SIDE EFFECTS: it can cause irritation, burning, itching, rash redness when applied topically.
--> POLYMYXIN: This is one of the active components of neosporin which attacks the invading pathogenic gram negative bacteria. In its mode of action, is the ability to combine with and disorganise structures of the bacterial cell which are responsible for the maintenance of the osmotic equilibrium of the cell thereby exposing the underlying peptidoglycan layer to lysozyme.
SIDE EFFECTS: Burning, redness, or irritation of the skin may occur.
--> BACITRACIN: This is also one of the active components of Neosporin. In its mode of action, it inhibits bacterial cell wall synthesis. This is achieved by preventing the final dephosphorylation step in the phospholipid carrier cycle, which interferes with the mucopeptide transfer to the growing cell wall.
SIDE EFFECTS: it may cause rash, itching/swelling (especially of the face/tongue/throat).
These three active components of Neosporin are combined to broaden the antibacterial spectrum. This means that at least one of the active components will effectively kill an invading pathogenic bacteria through its unique mode of action.
