Answer:
three systems affected are:
1. respiratory system
2. skeletal system
3. nervous system
Explanation:
From the text, three systems are affected, and they are:
1. respiratory system
2. skeletal system
3. nervous system
1. Respiratory system. The statement "the oxygen level in his blood was very low" highlights that the body cells were not getting enough oxygen during respiration. This could either be during the gaseous exchange in the lungs or during cellular respiration.
2. Skeletal system: When Barry fell, he broke his hip. The hip bone is the bone that forms part of the pelvic girdle in the skeletal system.
3. Nervous system: It was also suggested that the fainting episode was because the brain was not getting enough oxygen for respiration and metabolism, hence the brain (central nervous system) was affected

During science class, Mauricio made sketches of the major organelles of the cell. Which of the following is his sketch of a mitochondrion?
Answer: B
Explanation: I did The test
During science class, Mauricio made sketches of the major organelles of the cell. The second sketch describes a mitochondrion. The correct option is B.
What are mitochondria?The “powerhouses” of the cell, mitochondria, break down fuel molecules and harvest energy during cellular respiration. Chloroplasts and mitochondria probably started as microorganisms that were swallowed by larger cells (the endosymbiont theory).
A mitochondrion is a membrane-containing cell organelle. It is the site of energy-producing metabolic processes and cellular respiration. The process happens inside mitochondria.
Thus, the link between cellular respiration and photosynthesis is that the reactant in photosynthesis is a byproduct of cellular respiration.
Therefore, the correct option is diagram B.

How does meiosis play a role in the evolution of a species
A. It increases the reproduction rate of the species
B.it increases the amount of genetic variation in the species
C. It reduces the amount of competition between members of the species
D. It increases the ability of individuals in the species to obtain resources
Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.

Examples of obligate intracellular parasites that can only replicate inside a host cell are:
viruses and prions
rickettsia and viruses
viruses and bacteria
rickettsia and prions
Answer:
rickettsia and viruses
Explanation:
This is because obligate intracellular parasite are parasite that affect humans and they grow, reproduce and survive inside the host cell. These parasite cannot live or survive outside host cell but they live inside host cell, replicate and they depend on the host cell resources i.e the use host cell resources thereby causing harm on the host cell. rickettsia and viruses are parasite that can only survive inside a living organism.
Answer:
rickettsia and viruses

Photosynthetic organisms produce oxygen based on whether light is available for photosynthesis. These organisms also consume oxygen for cellular respiration in both light and dark environments. In three to five sentences, explain how these conditions relate to gross and net
productivity. (4 points)
Answer:
Gross productivity refers to the amount of carbon fixed.
Explanation:
Gross productivity refers to the amount of carbon fixed during the process of photosynthesis by all producers such as plants and algae etc in the ecosystem. A large part of the energy that is produced in the process of photosynthesis is used by the plants in the metabolic processes of the producers such as respiration. The net productivity indicates that carbon dioxide plants that is used during the photosynthesis process substracted from carbon dioxide the plants releases during the process of respiration.

Help a mate out in biology
Answer:
A. Spores
B. Meiosis
C. Spores grow by mitosis into gametophyte
D. Haploid (n)
E. Gametes (sperm and egg)
F. Mitosis
Explanation:
Alternation of generations is a system of life cycle exhibited by certain organisms such as algae, plants etc where they alternate between a haploid phase/generation and diploid phase/generation. In this life cycle, the SPOROPHYTE is the diploid (2n) multicellular body that forms haploid SPORES via meiotic division. These spores, however, grow into another multicellular body via mitosis called GAMETOPHYTE.
The GAMETOPHYTE refers to the haploid (n) body that produces the haploid gametes (sperm and egg) by undergoing mitosis. The haploid gametes produced unites in a process called FERTILIZATION to yield a diploid ZYGOTE that eventually mitotically grows into the SPOROPHYTE. Note that, the cycle repeats.

What is the grizzly bear?
The grizzly bear is a North American subspecies of the brown bear. Grizzlies are typically brown, though their fur can appear to be white-tipped, or grizzled, lending them their name. Grizzly bears are protected by law in the continental United States—not in Alaska—though there have been some controversial attempts to remove those protections in recent years.
Conclude: An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food.
Do your results suggest bears are decomposers? Explain your reasoning.
Answer:
No, because bears kill to get their food. They eat fish and they kill the fish to get them. If they left the fish carcass, decomposers would eat it. The bear makes the food for the decomposers, but it is not a decomposer itself... Does that make sense?
According to the kinetic theory of matter, how many particles that make up a substance are constantly in motion?
Answer:
D
Explanation:
According to the kinetic theory of matter, option D. all the particles that make up a substance are constantly in motion.
The Kinetic Theory of Matter states that all matter is made of particles that are atoms and molecules that are constantly in motion in the substance, therefore, particles of all matter have kinetic energy.
Some particles have more kinetic energy than other particles due to fact that all particles of matter do not move at the same speed even though particles of matter are constantly moving.The temperature of matter or object is the average kinetic energy of the particles in an object.Thus, the correct answer is - option D. all the particles.

Explanation:
Oil is a resource which has a great impact on our society because it is widely used in our daily life in the engine of vehicles. It is very necessary in the transportation sector but also adversely affected the ecosystem and the animals and plants living in that ecosystem due to production of harmful gases such as carbondioxide and carbonmonoxide gases that polluted the environment and affect the health of people.
Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are NOT the same width Now that you’ve created a model, explain why this makes sense (hint: it has to do with the number of rings for each nitrogen base)
I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.
A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).
In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across corresponding nucleobases on the other chain, which enables hydrogen bonding between the bases.
There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.
What does this have to do with the width of the DNA molecule?
The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.
So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.
Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.
DNA (Deoxyribonucleic acid) is composed of four nucleotides, namely, adenine, guanine, cytosine, and thymine.
Adenine and guanine are purines while Cytosine and thymine are pyrimidines.Purines are composed of two rings while pyrimidines are composed of only one ring.Purine forms bond with pyrimidine, i.e Adenine binds with thymine and guanine binds with cytosine.Adenine and thymine form two hydrogen bonds while guanine and cytosine form three hydrogen bonds.Thus, the relative pairing of the purine and pyrimidine with each other keeps the width of the DNA constant.
